Title: Stop valve
IPC: F16K27/02
Filed: 1959-07-17
Abstract: 921,335. Valves. McEVOY CO. July 17, 1959 [Dec. 19, 1958], No. 24692/59. Class 135. In a valve comprising a valve closure element movable against an annular valve seat and away from the seat to close and open the valve, means subject to the pressure of the controlled fluid on the inlet side of the valve are provided to automatically inject a sealant fluid under pressure between the closure element and its seat every time the valve is closed to effectively seal the valve. As shown, a valve body 10, Fig. 1, having inlet and outlet ports 11, 12 and a removable seat ring 19 fitted with a seal ring 28 is closed by a cap member 37 screw-threadedly engageable with a tubular valve stem 48 having an enlarged diameter bottom end 65 engageable with the seat ring 19 to close the valve. The bottom end 65 also provides a reservoir 60 for a sealant material 62, e.g., polymerized castor oil containing finely-divided mica and/or asbestos in suspension, in the end 65. A counterbore 66 slidably and sealingly mounts a plug 70 urged downwardly by a spring 75 abutting via a metal ring 72 a shoulder on the valve stem 48. The plug 70 is formed with an annular recess 78 engageable with hollow pins 77 passing through the stem to limit the movement of the plug with respect to the stem. A passage 90 through the stem, fitted with a check-valve 95 and an inclined port 91 connects the reservoir 60 with an annular recess 101 between the stem end 65 and plug 70 when the valve is closed. In the closed position of the valve, fluid in the valve inlet 11 passes through the pins 77 and through the ports 79 to act on the bottom face 82 of a piston 81 which is a close fit in the reservoir 60. The piston 81 is hence urged upwardly and sealant is forced through the passage 90 into the annular recess 101 between the plug 70 and the bottom of the stem. On the valve being opened the stem first moves away from the seat ring 19 closing the port 91 so that sealant is not entrained with the controlled fluid when the pins 77 engage the upper end of the recess 78 to unseat the plug 70. The inlet port 11 is tangential to the main valve chamber 13, see Fig. 2, so that the incoming fluid washes any foreign particles out of the valve chamber. These particles are received in a hollow plug 103 which may be periodically removed for cleaning.
Patent GB-623358-A (GB)
Title: Improvements in or relating to steam heating systems
IPC: D06F39/00
Filed: 1944-12-12
Abstract: 623,358. Steam heating systems; feedwater supply systems for boilers. HARRISON, E. P. Dec. 12,1944, No. 24909. [Classes 64(ii) and 123(ii)] In a steam heating system operating at a pressure substantially above atmospheric and comprising a steam generator supplying one or more heat exchangers, e.g. laundry irons, presses &c. a continuously pulsating flow of steam through the said heat exchangers, to increase the efficiency of the latter, is secured by locating a thermostatically-controlled steam or condensate release valve in the outlet therefrom, the thermostat being disposed in the discharge from the valve in such manner that it is alternately heated by the released steam &c. to close the valve and then permitted to cool to re-open said valve. Fig. 6 shows an installation comprising a boiler 72 with feed pump 73, heat exchangers 76 having steam supply and exhaust pipes 75, 77, and a make-up water tank 70 provided with water supply and overflow pipes 71, 83 and a return pipe 78, the latter communicating with the exhaust pipes 77 preferably through a condensate-receiving tank 79. The pipes 77 are of relatively small diameter or are provided with throttling valves or orifice members. The level of liquid within the tank 70 is controlled by a float 81, Fig. 5, associated with a valve 82 located in the pipe 71 between a multiple condenser unit 85 and the outlet nozzles 89 thereof, and the pipe 78, which terminates in an injector nozzle 91 with valve 92 actuated by a thermostat 93 in the outlet end of the pipe 71, is led to a mixing passage 88 between said valve 82 and nozzles 89. The arrangement is such that a fall in the level of water in the tank 70, due to replacement of normal water losses in the system, will effect opening of the valve 82 and a flow of water through the pipe 71 with consequent cooling of the thermostat 93 and opening of the valve 92, the latter closing when the temperature in the mixing passage 88 rises above a predetermined maximum and opening again when the temperature falls. The condenser unit 85, mounted within a hood 86 and provided with a drip pan 90, serves to condense water vapour in the tank 70 and also pre-heat the make-up water. A complete installation for a laundry, in which soft water is required to be supplied to a washer and steam to a dry tumbler, ironer, press, &c. is also described.

Filed: 1958-08-05
Abstract: 844,553. Serial adders. HAZELTINE CORPORATION. Aug. 5,1958 [Aug. 22, 1957], No. 25046/58. Class 106 (1). An adding circuit for two series mode binary inputs from 14 and 15 comprises a bistable carry circuit 43 set to " carry " (giving a low output at 45) by simultaneous input 1's, and to " no carry " (a high output at 45) by simultaneous input 0's by " and," " or " and " inhibit " gates 17, 26 and 36 and clock pulse generator 10. Output pulses from 10 are passed by a diode 67 when output terminal 63 is at a high potential, i.e. when " no carry " is registered and there is no output pulse from gate 36 (which would pass a negative pulse to point 66) or from gate 17 (which would switch 43 to " carry " and hence pass a negative pulse through capacitor 64), or when " carry " is registered and there is an output pulse from gate 17 (passing a positive pulse to 66) or from gate 36 (switching 43 to " no carry "). It will thus be seen that the circuit provides at 63 the correct sum series output. 17, 26 and 36 are conventional diode gates, and 43 an Eccles-Jordan transistor flip-flop.
