Filed: 1937-01-20
Abstract: 484,425. Liquid - blast switches. GENERAL ELECTRIC CO., Ltd., and GARRARD. C. J. O. Jan. 20, 1937, No. 1701. [Class 38 (v)] A liquid-break circuit breaker comprises a moving contact arranged within and secured to an enclosure which is arranged to move with said contact, and a fixed complementary contact adapted to extend into the enclosure and provided with a part adapted to act as a piston within the enclosure. At break, the pressure set up by an arc between the contacts forces liquid through an aperture or apertures in the enclosure-wall adjacent the arc to extinguish the arc, and is adapted to assist in separating the contacts. The arrangement is readily applicable to breakers not already equipped with explosion pots. As applied to one break of a conventional double-break circuit-breaker with a lowerable tank 1, the end of the bridge-member 9 passes through an aperture 14 in an insulating enclosure or tube 13 of rectangular cross-section and terminates in main and arcing contacts 12, 11, which respectively co-operate with fixed main and arcing contacts 7, 8. The tube 13 has a metal or insulating bottom-closure 15 and an aperture 16, or apertures, adjacent where the arc forms, so that when the breaker is being opened, and the tube moves downwards with the bridge 9, the pressure in the tube ejects a stream of liquid through the aperture to put out the arc. The bushing 4 carries a piston-like, metal or insulating plate 17 loosely fitting the tube 13, so as not only to exert a downward force on closure 15 to assist in opening the circuit, but also to neutralize the closing force acting on the operating rod which passes through the cover. Only the contacts 8, 11 may be located in the tube 13.

Abstract: 228,166. Baule, M. E. A. Jan. 21, 1924, [Convention date]. Magnetic compasses. - Relates to compasses employed in an electric distant-control or signalling system of the type in which the needle carries a conducting part moving in an insulated circular channel containing a liquid of low conductivity such as water. In the application to a liquid-filled compass, Fig. 4, the compass card 13, mounted on a pivot 15 in a receptacle 14 filled with a liquid of low conductivity, carries a terminal 16 connected by a wire to the pivot 15 and balanced by a counterweight 17. The terminal 16, is curved about the pivot 15 as centre, and moves within an annular insulating. vessel 27. The under side of the glass top 30 of the receptacle 14 is made convex to enable the bubbles due to the electrolysis to accumulate at its edge and escape through a tube 31. The lost liquid is replaced from a reservoir 29. In a modification the circuit connection to the pivot 15 is made through a rod extending through the top of the receptacle 14 to provide a counter-pivot with a drop of mercury to ensure good contact at the pivot. Stationary conductors 21 in the controlling or signalling circuit, and unconnected conductors 41 disposed between these to direct the flow of current through the liquid, are similarly curved about the pivot 15 as centre, and may be adjustable for correcting compass variations due to the ship's head. In the application to a dry compass the liquid is contained in a deep annular trough disposed around the compass bowl. Course -recording apparatus, e.g. such as described in Specification 145,708, may be controlled by a more powerful motor 52, Fig. 8, brought into action in opposite directions by deviations of the repeating index 40, at the dis. tant station. For this purpose the index carries a brush 47 movable over two nearly semi-circular conducting segments 48, 48<1> in an insulated disc 49 adapted to be rotated by the electric motor 52, the circuit connections being such that the motor rotates in one direction or the other according as the brush is on one or the other segment.

Convention date, March 31, 1934. [Class 8 (ii)] Solid refrigerant, such as carbon dioxide snow, is formed by discharge of fluid in the space between the inner and outer walls 66, 67 of an open-ended container. The container is placed in inverted position within a casing with hinged cover 79, pins 107, 110 moving in guides to fix its angular position. Fluid is supplied through a hollow stem 20, the mouth of which registers with a hole in the inner end wall. The fluid supply to the stem is controlled by a piston valve 19 operated by a cam rotated by lost-motion connection with pins on a plate 40 actuated by a handle 55 against a spring 51. An arm controlled by a spring 210 latches the plate 40, preventing fluid supply, when the cover 79 is raised. Lowering of the cover causes a tapered rod 206 to uncouple the latching arm. Rotation of the plate 40 by the handle brings it into position where it is latched by a bell-crank 49. When the container is filled with snow, an annular plate at its open end is pushed down, engaging pins 61 on a plate 57 which is pressed down to release the bellcrank 49 allowing the spring to close the valve.

Abstract: 404,808. Cooling cylinders. FOUTZ, C. R., 1409, Rice Street, Baltimore, U.S.A. Jan. 21, 1933, No. 2022. [Class 7 (ii).] In a cooling system in which cooling water is circulated in a closed circuit through pipes 3, 4 and a tank 2 by a pump 7, steam formed in the tank 2 is condensed in a condenser 15 and returned to the water circuit by alternative connections regulated by valves 21, 22. Rapid heating of the cylinders at starting is produced by closing the valve 21 and thus aerating the water with the air in the condenser which is forced by an air pump 18 through a pipe 20 into the suction pipe 4 of the pump 7. When the engine cylinders are hot, de-aeration is produced by opening and closing respectively valves 21, 23, air being thus forced to leave the system through a valve 27 which opens periodically at a predetermined pressure. For normal working the valve 23 is now opened and the vapour allowed to pass to the condenser 15, the pump 18 then returning the condensate to the system. Relative adjustment of valves 21, 22 will affect the pressure in the tank 2 and hence the steady temperature of the cooling medium ; this is further ensured by an adjustable pressureactuated valve 24 which closes, or partially closes, the pipe to the condenser on fall of pressure in the tank 2. The pump 18 may be driven independently of the engine. Pressure gauges 37, 38, a thermometer 39, and connections 28, 30 to external radiators may be provided. Specifications 321,193 and 328,664, [both in Class 7 (ii), Internal-combustion engines, Arrangement &c. of], are referred to.
