ELECTRIC LIGHTING OF HOUSES.

At the second ordinary meeting of the Dundee Institute of Architecture, Science, and Art, Mr. F. Grant Ogilvie, principal of Heriot-Watt College, Edinburgh, delivered a lecture on "Electric Lighting of Houses." Mr. Charles Ower (president) occupied the chair. The chairman said the lecture was one of two which had been specially arranged for in connection with the fact that Dundee was setting about introducing the electric light.

Mr. OGILVIE began by referring to the nature of electric light, and detailed some of the principal facts in relation to electricity which would have to be dealt with in its distribution in houses. He explained how the wire, heated by the electric current, gave off light, but at the same time, when made of certain metals, would melt. The lecturer then demonstrated the manner in which an electric lamp gave out light. The filament in the lamp, being made of carbon, glowed when the current was passing through, and during the process particles of carbon were thrown off, and in time the filament became thinner and thinner until it broke. The average life of a lamp was about 1,000 hours burning. The lecturer then explained the uses of the electric battery, and the signification of the electrical terms ampere and volt, which signified the strength of the current and the difference of electric pressure. By means of diagrams shown on the blackboard with coloured chalks, Mr. Ogilvie represented how electricity could be distributed in houses. The two wires were brought into the house, the one being at an electrical pressure of 100 volts above the other. These two wires were connected by another passing through the lamp, which glowed when the electric current was passed. The fittings for the distribution of the electricity were, he said, of importance. The conductor of the electric current was of copper or an alloy of copper, and to prevent electricity escaping from one wire to another, or into the material of the wall, the copper wire was entirely surrounded by some substance which offered great resistance to the flow of electricity. The way in which wires could be carried over a house was then detailed, and the use of the switch for turning on and off the current minutely explained, a switch being handed round among the audience to clearly show how it acted. It was usual also to have a wire not copper which formed part of the circuit, and which was of a substance easily fused. The object of this was to prevent any accident occurring in the event of some unforeseen contact between the two wires. This fusible piece of wire prevented the possibility of such an accident, as should such a mishap come to pass the wire fused and the injured part of the circuit was I cut out." A number of electric lamps suitable for fixing in different positions were exhibited to the audience. These and an exhibit of lead casings and various fittings were lent by the Brush Company. Mr. Ogilvie remarked that it was the exception now to find an ugly electrical fitting. The practical methods of measuring the electric power supplied to a house were explained generally and illustrated by the Shallenberger meter, an example of which was exhibited to those present. The lecturer at the close referred to the cost of electric light, especially as compared with the cost of gas, and by means of calculations demonstrated how the different prices might be arrived at and compared. He showed that under ordinary domestic conditions 1,000 c.p. of gas gave about the same amount of light as 12 Board of Trade units of electricity, so that the pence price of a B.T. unit taken as shillings might be compared directly with the quoted price of gas. To the price of this quantity of electric energy there would have to be added about one-fifth of the price of a lamp, say 9d. This addition, however, might soon be expected to be reduced by one-half. Though gas was at present cheaper than electricity,

[graphic]

the waste of the latter was very much less, as more gas was used than was actually required. A switch provided in a convenient place at the door of each room would enable one to turn the electric light on or off as desired. The great qualification of electric light, however, as compared with gas, was that it did not in any way alter the chemical condition of the air. Electricity heated the air, but did not burn it or vitiate it in any way, and the vitiation of the air by gas was one of the main items to be put in the balance against the additional price of electric lighting.

A number of questions were then asked by various members, and answered by the lecturer.

On the motion of Mr. F. W. YOUNG, seconded by ex-Bailie M'CULLOCH, a hearty vote of thanks was awarded to Mr. Ogilvie, and a similar compliment having been paid to the chairman the proceedings terminated.

ELECTRIC VEHICLES.

The question of introducing a commercially successful electric vehicle for use on common roads has long engaged the attention of electrical engineers in different countries. Two Italians claim to have succeeded where others have failed-the one by the employment of accumulators, and the other by the use of primary batteries. The first is a three-wheeled vehicle, made in the Castelnuovo Works of Garfagnana, on the Boggio system. Its total weight, excluding passengers, is said to be only 2 cwt. It is 6ft. long, 3ft. 4in. wide, and 4ft. in height, and can carry two passengers. There are 10 accumulator cells which, it is claimed, have as high a capacity as 25 ampere-hours per kilogramme of plate. These cells are, according to the Italian journal L'Industria, encased in an ebonite box. When in operation, and with a discharge of 12 amperes, the charge will last 10 hours. The motor absorbs 942 watts, and is stated to run at 3,000 revolutions per minute!

The second type of carriage has been devised by Mr. Malignani, the director of the well-known Udine electric light station According to Mr. Ferrucci, Mr. Malignani has invented a "special" kind of primary battery having a maximum of simplicity, and practically solving the problem of electric locomotion on common roads. No particulars are, however, given concerning the construction of the battery, but its efficiency is said to be very high. The Malignani electric carriage is built to accommodate three persons, and is constructed so that the dead-weight has been reduced to a minimum.

PHYSICAL SOCIETY.-Dec. 4, 1891.

been frequently referred to in the scientific papers. Alternate currents could be obtained from an ordinary direct-current dynamo by making contact with two points in the armature, say, by connecting these points to insulated rings on the shaft, and using extra brushes. A direct-current motor similarly treated transforms direct currents into alternating currents, or into mechanical power. If two pairs of points in the armature be selected, situated at opposite ends of two perpendicular diameters, then two alternating currents differing in phase by 90deg. can be obtained, and by choosing suitable points in the armature two, three, or more currents differing in phase by any desired angles can be produced. In ordinary motors the connections for doing this would be troublesome, but the Ayrton and Perry form, which has a stationary armature, lends itself readily to this purpose, for contact can be made with any part of the armature with great facility. A motor of this kind was exhibited, in which contact was made with four equidistant points on the armature. On connecting opposite points through fine platinum wires, and running the motor slowly, the wires glowed alternately, one being bright whilst the other was dark, and vice versa, thus demonstrating the existence of two currents in quadrature. When the four points on the armature were joined to the four corners of a square of platinum wire the wires became incandescent in succession, the glow appearing to travel round the square, and suggesting the idea of rotatory currents. A Tesla alternating-current motor was also driven by two currents, differing in phase by 90deg., obtained from the armature of the Ayrton and Perry direct-current motor above mentioned. The ease with which currents differing in phase by any amount can be obtained from such a motor, led the author to investigate theoretically the case of two circuits connecting opposite ends of two diameters inclined at any angle, a. Calling the currents in these circuits at any instant A, and A, he had found that:

A paper on A Permanent Magnetic Field was read by Mr. W. Hibbert, A.I.E.E., F.I.C. The author had noticed the approximate constancy of an "aged "bar magnet, and he obtained still greater constancy by attaching pole-pieces to a bar magnet, of such a shape as to give a nearly closed circuit of small "magnetic resistance." The pattern now described consists of a steel rod lin. diameter and about 24in. long, with a cast iron disc 4in diameter and ĝin. thick fixed at one end, the other end is fitted in a hemispherical iron shell which surrounds the bar and comes flush with the upper surface of the disc. An annular air space, less than in. wide, is left between the cylindrical surface of the disc and the inside of the shell, and when the bar is magnetised a strong magnetic field exists in this space. To use this field for producing electromagnetic impulses, a coil of wire is wound in a shallow groove on a brass tube which can slide axially through the annular space, thus cutting all the lines. The tube is allowed to fall by its own weight, a neat trigger arrangement being provided for effecting its release. The instrument exhibited had 90 turns of wire in the coil, and the total magnetic flux across the air space was about 30,000 C.G.S. lines. A large electromagnetic impulse is therefore obtainable even through resistances as great as 10,000 ohms. Tests of three instruments show that there has been practically no magnetic decay in seven months. The author therefore considers them satisfactory and is prepared to supply them as magnetic standards. To facilitate calculation, the number of lines will be adjusted to a convenient number, say, 20,000 or 25,000. Several uses to which the instruments are well suited are mentioned in the paper, and a simple way of determining permeability by the magnetometer method is described. Mr. Blakesley thought the name given to the instrument was inappropriate, for it really gave a constant impulsive E.M.F. Dr. Sumpner said the constancy of the sensibility of d'Arsvonal galvanometers was a measure of the constancy of magnets having and nearly closed circuits. Such instruments in use at the Central Institution had remained unchanged for several years. Prof. S. P. Thompson admired Mr. Hibbert's instrument, and thought it would be very useful in laboratories. Standard cells, he said, were not always reliable, and condensers were the most unsatisfactory of electrical standards. On the subject of permanency of magnets, he said that Strouhal and Barus found that magnets with nearly closed circuits were most constant, and that, to give the best results, the hardness of the steel should be less the more closed the circuit. Mr. Hookham had also found that by using a nearly closed circuit, and reducing the strong magnetisation by about 10 per cent. great constancy could be obtained. Some years ago he (Prof. Thompson) had tried the effect of ill-treatment on magnets, and observed that touching or hitting a magnet with non-magnetic material had little effect, whilst similar treatment with iron or magnets affected them considerably. Suddenly removing the keeper of a magnet tended to increase the magnetism, whilst putting a keeper on suddenly had the reverse effect. Strouhal and Barus had also investigated the temperature coefficient of magnets, and found that this might be reduced by subjecting the magnet to rapid changes of temperature after the first magnetisation and then remagnetising. Mr. W. Watson enquired what was the percentage fall in strength of Mr. Hibbert's magnets. The bars used in magnetic surveys had been tested frequently, and they lost about 0.5 per cent. in six months. The President asked what was the temperature coefficients of the magnets described in the paper? Mr. Evershed, he said, thought it was between 0·01 and 0·05 per cent. for ordinary magnets. He thought the instrument shown by Mr. Hibbert would be of immense value if the magnet was really permanent. By it ballistic galvanometers could be readily calibrated, and when combined with a resistance-box, it could also be used as a standard for current; for since the constant of a ballistic galvanometer for quantity can be determined from its constant for current, if the periodic time be known, conversely that for current can be found from the constant for quantity. In some instances this would be of great use. Speaking of the temperature coefficient of condensers, he said that in some cases the specific inductive capacity of dielectrics diminished with rise of temperature, whilst in others it increased. Mr. Hibbert, in reply, said he found the temperature coefficient of his magnets to be, roughly, about 0-03 per cent., but he had not investigated the matter very carefully. In making his measurements no correction had been made for the variation of capacity of his condenser with temperature.

Mr. Walter Bailey, M.A., took the chair, and the President communicated a "Note on Rotatory Currents." The subject, he said, was probably familiar to most persons present, for it had

This case came before Mr. Justice Matthew, in the Chancery Division of the High Court of Justice recently. The plaintiffs, as owners of patents for an invention of improvements in electric lamps, also of the Cheesbrough patent for an improvement in the preparation of the filaments used in the lamps, brought this action to restrain by injunction during the continuance of the letters patent, the defendants, W. J. L Hamilton and J. C. Roxburgh, of 4B, Newland-terrace, Kensington, from manufacturing, selling, letting, on hire, supplying, or using any electric lamps manufactured according to or in the manner described in the specifications filed in pursuance of the plaintiffs' letters patent, and generally from infringing the plaintiffs' rights in respect of such letters patent.

Mr. Bremner, who appeared for the plaintiffs, said the defendant had put in a defence, but did not appear to defend the action. The plaintiffs' patents had been twice upheld by the Court of Appeal, and therefore the sole question was one of

infringement. He would call evidence to show that the incandescent electric lamps sold by the defendants consisted of a glass receiver, two platinum leading wires sealed through the glass, and attached to a carbon filament, which was a distinct infringement of the plaintiffs' patents. The carbon filament was prepared according to the Cheesbrough process, which also was an infringement of plaintiffs' patent rights.

Formal evidence was called which bore out the opening statement of counsel.

Mr. Bremner waived an enquiry as to damages. Mr. Justice Matthew granted an injunction as prayed, and delivery up of all infringing lamps, with costs.

COMPANIES' MEETINGS.

OXFORD ELECTRIC COMPANY, LIMITED.

On Saturday, the 12th inst., the first ordinary meeting of this Company was held at the offices, 45, Broad-street, Oxford, Mr. J. Irving Courtenay, chairman of the Company, presiding. The notice convening the meeting having been read, The Chairman said: This is a formal meeting of the Company, called in compliance with the statute within four months from the incorporation of the Company, and is commonly known as the statutory meeting. There are no accounts to be presented, but the Directors gladly embrace the opportunity thus afforded of explaining the position of the Company, and inviting enquiry and co-operation from the shareholders and others attending the meeting, The Electric Installation and Maintenance Company obtained a provisional order, which was confirmed by Parliament on the 4th of August, 1890, under which that company has powers to supply electricity to the whole borough of Oxford. The Directors being desirous of establishing the business as a local enterprise, have made arrangements for transferring the parliamentary powers to the Oxford Electric Company, Limited, and the necessary formalities are being carried out for obtaining the consent of the Board of Trade and the Corporation of Oxford to the grant of a provisional order for the purpose. In the meantime, the Oxford Company, having been duly constituted, entered into a contract with the Electric Construction Corporation, of London and Wolverhampton, by which the Oxford Company purchases all the rights under the provisional order, and provides for the construction of a fully-equipped generating station for the supply of electricity, together with all necessary street works, mains, transformers, and storage batteries, for the supply of an important area which it is first proposed to deal with. This area comprises High-street, Cornmarket-street, Broad-street, Magdalen-street (from the corner of Beaumont-street to Cornmarket-street), and Catherine street. The area in question, bounded by the streets named, comprises 12 colleges, 39 public buildings and churches, nine hotels, and 337 shops, offices, and private houses. Provision is made in the contract for a supply of electricity sufficient for about 15,000 lamps actually connected with the Company's mains. The contract provides for the purchase of the lease of the land at Osney, formerly known as Cannon Wharf; the construction of the building, of which drawings may be seen on the walls; the generating and distributing plant; the cost of incorporating this Company and obtaining a transfer of the provisional order; a supply of lamps, wire, fittings, etc, to the value of £500; and a sum of £1,500 for the ordinary expenses of the Company. In the contract, the deposit of £1,500 as security paid to the Board of Trade is also provided for, but will be repaid to the contractors on satisfaction of the provisions of the order. Under this contract an agreement has been made for the erection of the generating station with Mr. Kingerlee, the well-known local builder and contractor, who is pushing on the work vigorously, and expects to have all completed by March. During the construction of the building the mains will be laid throughout the compulsory area, so that a supply of electricity will be furnished with all possible speed. The consideration for all these works and payments, including the provisional order, is a sum of £50,500, payable in fully paid-up shares of the Company. Assuming the capital expenditure to be £50,000, the commercial result of the enterprise may be estimated as follows: Revenue-258,750 units of electricity at 8d., and rent of meters..

Expenditure Running expenses, rent, salaries, insurance, etc........

Net income (or 7 per cent. on £50,000)

The extension of the Company's business to the residential district north of the city and the other important parts of the borough outside the area comprised in the above calculations, should materially add to the dividends of the Company, as the capital of £50,000 includes buildings, street works, etc., capable of providing for a larger business. The cost to the consumer at 8d. per Board of Trade unit is equal to about d. per lamp per hour, or, in other words, the current necessary to supply 30 10-c.p. lamps for one hour or their equivalent for a proportionate time. Owing to the facilities for economising the use of electricity, by the provision of a sufficient number of switches judiciously placed in the consumer's premises, it is found by experience that though the relative cost of electricity at 8d. per unit, as compared with gas at 3s. per 1,000 cubic feet, appears to be higher, yet in actual practice the amount paid by the householder in each case would not materially differ, but when the convenience and advantages of the electric light and its indirect economies, such as the saving in

renewals of decorations and cleaning of rooms, are taken into account, it is really in the long run cheaper than gas. For a city like Oxford the electric light is almost a necessity. The experience already obtained at the South Kensington Museum and the British Museum proves the value of electricity as a means of illumination for such institutions, while the absolute safety of the method of supply adopted by this Company makes it specially suitable for lighting the various colleges, museums, and public buildings in the city with their priceless contents. I think a few words of explanation are necessary as to the system of electrical supply. I do not propose, however, to go into details, which have been already published, and Mr. Thomas Parker, the chief engineer of the Electrical Construction Corporation, who has designed and is carrying out the installation, is here to-day, and will be ready to give any detailed explanation that may be required. The system proposed may be described as a moderate high-tension continuous-current of 1,000 volts, with continuous-current transformers to convert to 100 volts, and secondary batteries to supply current to the lamps during the hours of minimum supply, thus allowing the generating station to be shut down entirely. The high-tension continuous current will be conveyed by underground mains, which never come in contact with the houses of the consumers, the current delivered to the consumers being absolutely safe, steady, and its continuity secured by the use of the storage batteries. Reliable meters will be supplied to each customer, and charged for by quarterly rental, as in the existing system of gas supply. The cost of fitting premises for the electric light varies with the character of the buildings and the nature of the fittings, which may be of a simple and inexpensive character, or costly designs, according to the taste of the customers. The Company have already been estimating for a few buildings in this city, which may be taken as typical, and comprise : Clarendon Press.... Magdalen College. Christ Church... Metropolitan Bank

The wiring and fitting of ordinary premises, such as dwellinghouses, shops, and hotels, with simple fittings, can be very well done at the cost of 30s. per lamp; factories and similar buildings at somewhat less; colleges, museums, and similar institutions according to the condition and character of the buildings. All work of this kind is done under stringent rules framed by the fire insurance companies, and controlled also by the provisions for safety contained in the provisional order. No other method of artificial illumination can be compared with it for freedom from risk of fire, providing you have suitable fittings and a system of supply such as has been sketched out for the supply of the city of Oxford. As I have already stated, the Company has made its arrangements to carry out all the necessary works without any public issue of capital, but the intention is, when the preliminary work is completed, to give the public an opportunity of subscribing to the capital, and thus the inhabitants of Oxford will be able to acquire an interest in this important local enterprise.

Mr. T. Parker explained matters of detail connected with the proposed system of supply, and incidentally mentioned that Sir William Thomson and Prof. Silvanus Thompson had both recently inspected the electrical plant prepared for this installation and that at Sydenham, and highly approved of the working of the continuous-current transformers, Sir William Thomson having expressed the opinion that their success would lead to the alternating-current system being eventually superseded.

A strong feeling in favour of the introduction of the electric light into the colleges, museums, etc., was very generally expressed, and the prospects of the Company appear to be satisfactory. It was stated that the works were making rapid progress, and that the supply of electricity would be commenced early in the spring.

COMPANIES' REPORTS.

ELECTRIC CONSTRUCTION CORPORATION. Directors: Sir Henry C. Mance (chairman); Sir Daniel Cooper, Bart, G.C.M.G.; Messrs. John Irving Courtenay, George Dibley, Joseph Ebbsmith, Henry P. Holt, J. Spencer Balfour, M.P. (vicechairman); Joseph Moseley, James Pender, John B. Verity, H. Granville Wright. Manager and chief engineer, Thomas Parker, M.I.C. E. and M.I.E.E.

Report of the Directors to be submitted to the shareholders at the ordinary general meeting, to be held at Cannon-street Hotel on Tuesday, 22nd inst., at 3 p.m.

In submitting the accounts of the Corporation up to 30th September last, the Directors point out that the period embraced by the previous profit and loss account extended over nearly 16 months, whereas the present report only includes the working at Wolverhampton for one year, and at the Millwall works for eight months. The Directors are happy to state that the business of the year has been of a satisfactory and promising character, and it will be seen from the accompanying accounts that it has resulted in a profit balance of £46,166. 16s. 8d., from which the Directors have carried £10,000 to reserve for depreciation, leaving a net balance of profit and loss for the year of £36,166. 16s. 8d., which, with the £3,877. 11s. 1d. carried forward from last year, makes a total of £40,044. 7s. 9d. available for disposal. The development of the electro-chemical patents of the Corporation is advancing to the satisfaction of the Directors, and a substantial addition to

future profits may he expected from this source. As the shareholders are already aware, Mr. Ebbsmith has resigned his appointment as managing director of this Corporation in order to take charge of the British Electro-Chemical Agency, Limited, to which these patents have been transferred, but in order that the Corporation might not be deprived of the benefit of his experience he has been elected to fill the vacancy on the Board caused by the lamented death of Sir Robert Fowler. The Directors have leased the Millwall works on favourable terms to the Electrical Power Storage Company, Limited, with an exclusive license to that company to use the storage battery patents belonging to the Corporation. This arrangement has already proved of great advantage to both parties, and it has the further merit of enabling the manager and chief engineer, Mr. Parker, to concentrate his energies on the important contracts and work which the Wolverhampton works have in hand. In continuance of their previous policy, as approved by the shareholders at the last general meeting, the Directors have written off capital expenditure the sum of £20,000 out of the sale of patents sold or transferred to other companies during the past year. The sale of these patents will not in any way prejudice the working of the Corporation; on the contrary, it is confidently expected that their development will bring a considerable amount of work to the factory at Wolverhampton. The Directors have pleasure in recommending a dividend of 6 per cent., payable on 22nd January next, leaving a balance of £10,721. 19s. 4d. to be carried forward to the present year's account. The prospects of business are very satisfactory. The Corporation is at present carrying out, in addition to ordinary work, large and important contracts for the Liverpool Overhead Railway, the electric lighting of the city of Oxford, and also for the electric plant for the Crystal Palace district. The balance of the authorised debenture issue is now required for the working of the Corporation, and the Directors will be glad to receive applications, as soon as possible, on the enclosed form, in order to avoid the expense of a public issue. In accordance with the articles of association, four of the Directors-viz., Sir Henry Mance, with Messrs. Ebbsmith, Holt, and Moseley-retire from the Board, all of whom are eligible and offer themselves for re-election. Messrs. Broads, Paterson, and Co., the present auditors of the Corporation, retire and offer themselves for re-eleetion. In conclusion, the Directors desire to express their continued and increased confidence in the future of the undertaking.

FOWLER-WARING CABLES COMPANY.

Directors: Messrs. Wm. Fowler (chairman), Walter Chamberlain, R. W. Eddison, George Fleming, the Hon. J. S. GathorneHardy, M.P., Colonel J. T. North, R. S. Waring.

Report to be presented to the shareholders at the third ordinary general meeting, to be held at Winchester House, Old Broadstreet, E.C., on Friday, the 18th inst.

In submitting their second annual report the Directors express their regret that they are unable to allow a profit on the work of the year. At the same time, they are glad to say that the business of the Company has made great progress. There has been a marked increase in the volume of business done as compared with last year, and the gross profit has been sufficient to cover all ordinary and some extraordinary expenses. The factory is well equipped and organised, and the work done there is unsurpassed. Since the close of the financial year numerous orders have been received, to say nothing of many important enquiries. The Directors, therefore, fully retain their previously expressed confidence in the future of the business, further details of which will be found in the annexed report of the general manager. There is, however, no manufacturing business in which the competition is keener than it is in ours, and a new undertaking must necessarily require time for development and to make its manufactures known. Meanwhile, as materials must be paid for almost on delivery, and as it is often necessary to give considerable credit to our customers, as well as to provide for special additions to plant to enable us to meet the new demands constantly being made by electrical engineers, the Directors believe that the employment of a larger working capital than the Company possesses would be justified by results, and would materially assist in bringing the concern to a dividend-paying position. The Directors have again not drawn their fees, but on this occasion they have debited the amount in suspense, as they anticipate a state of things when the payment of this amount will be fully justified by the condition of the business. The retiring directors, Mr. Walter Chamberlain and Mr. R. W. Eddison, being eligible, offer themselves for re-election. The auditors, Messrs. Cooper Bros. and Co., offer themselves for re-election.

GENERAL MANAGER'S REPORT.

During the past year the Company has made notable progress in each department of its work, and our manufactures have been 53,139 18 7 successfully applied and their efficiency proved in every important branch of electrical engineering. In electric lighting, among the larger orders we have delivered to the London Electric Supply Corporation 10 miles of large concentric conductors for the distribution of their high-tension currents through the streets of London. These cables are now laid and are working daily under conditions which demand the most perfect efficiency; the best testimony to 25,000 9 0 their success is the fact that the corporation have ordered an
