Abstract

9144. Treves, M., and Raffegeau, D. V. M. April 22. Heating liquids.-Relates to apparatus for heating water, or any other liquid, and delivering it at any temperature desired between that of the atmosphere, or a cold supply, and that of the boiling point of the liquid. The liquid is stored in a tank 2 and passes by an outlet 8 to a vessel 10, in which a given level is maintained by a float and valve 12. From this vessel, the water passes by an outlet 14 to the heating-apparatus C, or by an outlet 14<a> to a refrigerating-coil d. The boiler, preferably heated by gas, consists of the space between two spherical calottes g communicating with a cylindrical chamber i, the discharge from which is regulated by a cock a<1>. The cold-water passes by a pipe f to a cock b<1>. The cocks a', b<1> are each connected to a lever pivoted at V, so that as one cock opens, the other closes, and vice versÔ. In the outlet from the mixing-chamber m, a thermometer 0 is placed. The two cocks a<1>, b<1> are insulated from one another. In order that water at any temperature between that of the cold supply and the boiling point of the liquid may be obtained, the operating-lever V is fitted with an extensible end V<111> adapted to work over a diagram D. An arc of a circle, corresponding to the effective range of the lever V, is divided, in the case of water, into 100‹ as shown. Along one radius, a number of divisions are set out equal to the possible range of the temperature of the cold supply, and then corresponding numbers are connected by diagonal lines, the remaining lines being drawn approximately parallel. To adjust for the supply at any given temperature, the lever is first lengthened to the radial graduation indicating the temperature of the cold supply, and it is then moved on to the lines passing through the desired temperature on the bottom line.
