Title: Method and Apparatus for Inducing Heat-changes.
Inventor: VUILLEUMIER RUDOLPH
IPC: F02G1/04
Filed: 1918-06-04
Abstract: 136,195. Vuilleumier, R. June 4, 1918. Heating water etc.; heating air &c.-A method of inducing useful temperature effects, say for heating feed water or for refrigeration, consists in producing primary heat changes in a portion of a fluid, thereby inducing, by the expansion and contraction of the fluid, secondary heat changes in another portion of the said fluid, then abstracting separately the heating and cooling effects induced by the secondary heat changes. The fluid is displaced through regenerators into and out of different temperature regions in heat-interchanging relations with the water &c. to be heated or cooled. Air in a cylinder 4, Fig. 2, having a heating- jacket 9, a cooling-jacket 15, and a refrigerating- jacket 12, is displaced by the alternate reciprocations of pistons 5, which are of a material of low conductivity and are centrally bored so as to leave a large number of heat absorbing radial walls forming regenerators. A regenerator may consist of thin perforated or slotted metal plates arranged so as to form a large number of air passages. The apparatus shown in Fig. 4 comprises a high-temperature inductor 22 and a low-temperature inductor 23, the former having heating and cooling jackets 26, 27 and the latter cooling and refrigerating jackets 31, 30. The heating-jacket may be heated by gas jets 28, vent-holes 28' being provided for the escape of the gases. To reciprocate the inductor pistons 24, they may be connected to pistons in cylinders 32, 33, to which pressure fluid is admitted alternately. The inductor pistons may be reciprocated by the fluctuations of air pressure in the inductors. In a modification, air is displaced from cylinders having low-conductive linings through exterior heating. cooling and refrigerating spaces by means of a reversible fan or propeller. In a further modification, high and low temperature inductors having reciprocating pistons as described above are mounted radially on a rotating shaft, the pistons moving by gravity as the shaft revolves.

Valves closing after predetermined flow.-In apparatus for proportioning the flow of two liquids, as in adding chemical reagents to water to be purified, a pipe 45 is pivoted at 47 in the reagent tank 46, and its open end is supported by a cord 44 wound on a drum 43 which is rotated slowly through gearing 41, Fig. 2, by a water-wheel 38 so as to lower the pipe and to run the reagent from the tank at a rate dependent upon the flow of water to be treated This water is supplied by a pipe 14 to a dividing-tank 13, and the main portion passes by orifices 16, 22 into the treating-tank 10. A part of the water passes by a pipe 24 from the tank 13 to another dividing-tank 25 wherein dividing-notches 31, 32, Fig. 2, are adjusted by a sliding valve 33. One part of the water passes directly to the treating-tank by pipes 34, 35, and the other part operates the water-wheel 38 to regulate the flow of reagent. In the Specification as open to inspection under Sect. 91 (3) (a) it is stated that the supply valve 15 in the water-supply pipe 14 is operated automatically by a lever 55 controlled by a counterweighted bucket 60 which is provided at the bottom with a float valve 64. The valve is opened by the action of the counterweight. When the tank is full the water overflows into and fills the bucket 60 which then drops and closes the valve. As the tank empties, the float valve 64 opens and empties the bucket, whereupon the counterbalance weight raises the bucket again and opens the valve. This subject-matter does not appear in the Specification as accepted.

Abstract: 513,209. Purifying acetylene. I. G. FARBENINDUSTRIE AKT.-GES., and JOHNSON, G. W. March 28, 1938, No. 9475. Addition to 386,052. [Class 1 (i)] [Also in Group IV] Gases containing acetylene prepared by thermal or electrical treatment of hydrocarbons are purified by washing with an organic liquid already saturated with gaseous impurities from the gases to be treated, in order to remove tarry polymers. When the absorbtive power of the liquid for the impurities subsides, the deposited substances may be removed by centrifuging. It is preferred continuously to branch off a part of the washing liquid, centrifuge off the deposited impurities and return the liquid to the washing container. The washing liquid is eventually distilled in order to remove also the impurities dissolved therein. Any naphthalene present in the gas is preferably removed as a separate step to prevent the saturation of the washing liquid by this substance. An example is given of the purification of acetylene by means of gas oil, 30 per cent. of the oil being continuously withdrawn per hour, centrifuged and returned to the washing container.
