Title: Improvements in or relating to devices for counting heat units
IPC: G01K17/18
Filed: 1969-01-23
Abstract: 1,210,193. Fluid. SOC. POUR LA MESURE DES CALORIES and J. TOPART. 23 Jan., 1969 [15 Feb., 1968], No. 3939/69. Heading H1N. [Also in Division G1] In a fluid flow meter 1 a spring-blade switch 19 is momentarily closed after a given rotary displacement of a shaft 34, so as to indicate passage of a predetermined volume of fluid through the meter. The shaft carries a pin 35 to engage a pivoted member 36 having a pin 40 which engages a pivoted inertia weight 39. Further rotation allows the pin 40 to clear the weight which rotates to bring a pin 41 into contact with a blade of the switch to close it. Subsequently the pin 35 clears the member to restore the assembly to its initial position. In an alternative embodiment, Figs. 4, 5, a spring 56, is mounted on the shaft 34 and rotates therewith so that for a given direction of rotation it engages a notch 52 in a cam 51. Rotation of the cam causes one of the radial pins 53 thereon to engage a pivoted inertial weight 54 which engages a contact of the switch 19 to close it. In either embodiment oppositely-directed rotation does not produce closure. It is stated that the inertia weight may be replaced by a spring.

Abstract: 1,006,459. Heat exchangers for cooling gases. COMMISSARIAT A L'ENERGIE ATOMIQUE. Feb. 4, 1963 [Feb. 13, 1962], No. 4449/63. Headings F4K and F4S. In a heat exchanger in which a gas is cooled by another fluid, a method of increasing the rate of heat transfer from the gas comprises introducing into the gas as it enters the heat exchanger an auxiliary liquid which does not vaporize under working conditions, and separating the gas from the liquid at the gas outlet end of the heat exchanger. In the heat exchanger shown for carrying out the method, the hot gas a flows through tubes 2 over which flows another fluid b receiving heat from the gas. The auxiliary liquid, e.g. a eutectic mixture of diphenyl and diphenyl oxide, enters the tubes 2 through holes or orifices 13. These may be arranged to form the liquid into droplets and to give the liquid a gyratory motion. After the gas-liquid mixture has passed through the tubes the liquid is separated in a member 14 and the gas is withdrawn through a duct 3. The separated liquid collects in a sump 8 from which it is recirculated to the orifices 13 by a variable delivery pump 9. Hairpin or coiled tubes may be used instead of the straight tubes shown.
