Title: Fluid pressure regulating valve device
IPC: G05D16/06
Filed: 1957-12-16
Abstract: 837,052. Pressure-regulating valves. WESTINGHOUSE AIR BRAKE CO. Dec. 16, 1957 [Dec. 28, 1956], No. 39025/57. Class 135. In a self-lapping pressure-regulating valve the delivery pressure acting on the upper surface of a fixed-area diaphragm 9 is balanced by the supply pressure acting, through a passage 39, on the underside of a second diaphragm 12 of variable effective area, the variation in area being effected by downward movement of a plunger 5 to progressively disengage the upper surface of the diaphragm 12 from a conical seating 14 formed in the valve casing. Supply and pressure-release valves 2, 3 are connected by a stem 23 and engage seatings formed in an operating plunger 4 and plunger 5. Upon depressing plunger 4, valve 2 is unseated to allow pressure fluid to pass from inlet port 7 to delivery port 6 and, through a passage 40, to act upon diaphragm 9 and thus depress plunger 5 and unseat the central portion of diaphragm 12, the valves 2, 3 being reseated when equilibrium is established. Progressive operation of plunger 4 results in a larger area of diaphragm 12 being exposed to the supply pressure, thereby increasing the delivery pressure. Valve 3 governs venting through an atmospheric port 8, and downward movement of plunger 5 carries a flange 33 clear of an opening 34 in the diaphragm seating 14 to ensure that the upper surface of diaphragm 12 is subjected to atmospheric pressure through port 8.

Title: Improvements in or relating to apparatus for filling containers
Inventor: HARLEY GERALD BRUNSWICK
IPC: B67C3/16
Filed: 1969-08-06
Abstract: 1,255,523. Bottle filling apparatus; filling bottles with powders. G. B. HARLEY, G. HARLEY, and P. B. HARLEY. 13 July, 1970 [6 Aug., 1969], No. 39412/69. Headings B8C and B8T. Apparatus for filling containers with fluid (including particulate material) comprises a sealing pad 1 carrying a filling tube 2, a suction probe 3 and a pressure probe 4. Fluid material enters the container 5 until level 5A is reached. Excess fluid enters the suction probe 3, causing a pressure rise above the fluid, the rise being sensed by the pressure probe 4, thereby terminating the fluid flow. The filling cycle starts when a bleed valve 7 is closed by a mechanical actuator 9 operated when the container 5 reaches its filling position. Port 10 of a fluidic relay receives a signal, the output of which at port 12 passes to a booster valve 13, causing high pressure air from source B to operate the piston 14a, resulting in the pad 1 abutting the container and mechanically causing valve 15 to admit fluid to the filling tube 2. When the fluid reaches level 5A, the pressure increase is sensed by a diaphragm amplifier 17 which relays pressure from source A to a port 18 of a module 11, causing the output at port 12 to switch to port 19 through which passes the compressed air from A to port 20. Module 11 is, thus, held in this mode until valve 7 is again actuated, this time disconnecting port 10. The switching of output causes the booster valve 13 to disconnect cylinder 14 from source B allowing spring 21 to lift the pad 1 from the container, thereby closing the fluid supply valve 15. The fluid supply can be manually terminated by actuating a piston 22.
