Сторінка 57 - ... these coefficients are to be increased respectively as follows : Ten per cent, where the exposure is a northerly one, and winds are to be counted on as important factors. Ten per cent, when the building is heated during the daytime only, and the location of the building is not an exposed one. Thirty per cent, when the building is heated during the daytime only, and the location of the building is exposed. Fifty per cent, when the building is heated during the winter months intermittently, with...

Сторінка 337 - No alterations shall be made in the work shown or described by the drawings and specifications, except upon a written order of the Architect, and when so made, the value of the work added or omitted shall be computed by the Architect, and the amount so ascertained shall be added to or deducted from the contract price.
Сторінка 338 - All payments shall be made upon written certificates of the Architects to the effect that such payments have become due.
Сторінка 27 - ... gas. This element is practically inert in all processes of combustion or -respiration. It is not affected in composition, either by passing through a furnace during combustion or through the lungs in the process of respiration. Its action is to render the oxygen less active, and to absorb some part of the heat produced by the process of oxidation.
Сторінка 239 - The principal radiating surface is made of parallel lines of i^-inch, or larger, pipe, placed under the benches and supplied by the return current; this has in all cases a pitch toward the heater. An illustration of the method of piping as designed by AH Dudley of the Herendeen Mfg. Co. is shown in Figs. 193, 194, and 195 so clearly as to require no special explanation. Any system of piping which gives free circulation and which is adapted to the local conditions will give satisfactory results. The...
Сторінка 136 - Standard Library of Tales." There Is a great difference of opinion as to the relative merits of the two sisters as authors.
