Title: Improvements in and relating to fluid flow control valves
IPC: G05D7/06
Filed: 1953-05-27
Abstract: 776,266. Valves; regulating volume of flow of fluids. GENERAL ELECTRIC CO. May 27, 1953 [May 29, 1952], No. 14767/53. Class 135. A diaphragm valve 16 which has little or no inherent bias is separately biased to the closed position by a spring 31, and it is opened by a pressure differential produced across the diaphragm by an electro-magnetically operable pilot valve 25. When the valve is closed, inlet fluid can flow past a strainer 6 and through a port 29 in the diaphragm to build up pressure on the upper side of the diaphragm to keep the main valve closed. When the solenoid 30 is energized, its armature 25 is raised to uncover an axial port 27 in the diaphragm, and as the fluid pressure above the diaphragm can now flow to the outlet 7, the inlet pressure acting on the underface of the diaphragm valve will lift it to the open position. An apertured disc 12 in the outlet ensures a uniform flow irrespective of variations in pressure.

Title: Improvements in liquid level control apparatus, particularly for low boiling point liquids
IPC: G05D9/12
Filed: 1955-05-23
Abstract: 769,768. Regulating liquid levels. MACHLETT LABORATORIES, Inc. May 23, 1955 [June 1, 1954], No. 14799/55. Class 123 (1). The level of liquid air, or other low boiling point liquid, in a vacuum cup 12, Fig. 1, is maintained constant by the addition of further liquid 15 from a reservoir 14, if and when required, the flow of liquid 15 being effected by compressed air which is supplied to the reservoir through pipe lines 19, 17 under the control of a valve 18. The valve 18 is actuated by a solenoid 22 in an electric circuit which includes contact members 26, 27 comprising a switch 38 adapted to be closed and so open the valve 18, to permit compressed air to flow to the reservoir 15 and liquid air from the latter to the cup 12, when the liquid in the cup uncovers a cylindrical bulb member 36 depending thereinto. As shown the switch 38 is supported by a bracket 29 between the limbs of which is located a flexible metallic bellows 33, the latter having a free closed end 34 adapted to abut a spring-pressed plunger 31 upon which the contact member 26 is mounted, the other end being connected to a member 43 which is secured to a limb of the bracket 29 and effects communication between said bellows and a tube 35 leading to the bulb 36. The bellows and bulb are filled with, for example, atmospheric air, and the arrangement is such that, with the bulb immersed in the cup 12 and the air in the bulb and bellows supercooled, the switch will remain open; as the liquid level in the cup falls, however, the supercooling of the air is discontinued, with the result that the bellows expands to depress the spring plunger 31, close the switch 38, and shift the valve 18 to establish communication between the pipe lines 19, 17 ; in the normal position of the valve 18 the line 17 is open to atmosphere through a duct 20. The invention is described in connection with apparatus used in the manufacture of high vacuum electron tubes.
