Patent GB-862137-A (GB)
Title: Improvements relating to the control of liquid level
Inventor: REDDING ROBERT JAMES
IPC: G05D9/12
Filed: 1958-07-14
Abstract: 862,137. Automatic liquid level control systems. EVERSHED & VIGNOLES Ltd. June 30, 1959 [July 14, 1958], No. 22514/58. Class 38 (4). In an automatic liquid level control system the liquid, in rising to a predetermined level, completes a circuit between two electrodes extending to different levels and thereby produces a potential which initiates control through a cold cathode discharge tube operating a relay. As shown, when the level of liquid, e.g. oil, in a tank 1 rises sufficiently to complete a circuit between electrodes 2 and 3 an alternating voltage from a mains transformer 5 is applied to a transformer 9 the output of which is rectified to produce a direct voltage across a resistance 12. This voltage renders a cold cathode discharge tube 18 intermittently conductive since it is added to an alternating voltage grid bias, obtained from a secondary winding 19 of transformer 5, which normally maintains tube 18 near the point of conduction. Conduction of tube 18 energizes a relay 30 to stop or start pumps (not shown) which deliver or remove liquid to or from tank 1 so that further rise in liquid level is prevented. A resistor connected between electrodes 2 and 3 may serve as an alternative means of normally maintaining tube 18 near the point of conduction.

Title: Improvements in method and apparatus for revaporizing liquefied gas
IPC: F17C9/02
Filed: 1938-08-03
Abstract: 517,641. Revaporizing liquefied gases. LINDE AIR PRODUCTS. Aug. 3, 1938, No. 22904. Convention date, Aug. 7, 1937. [Class 8 (ii)] [Also in Group 11] A portion of the liquefied gas in a container 10, e.g., oxygen in an aircraft, is segregated by a sleeve 66 removable through the neck and open at the bottom. Development of pressure in the gas space 76 above the liquid forces liquid up through a tube 18 within the sleeve into a steam &c. heater 14 where it is vaporized; the gas produced passes back through the sleeve, within a tube 22 to a coil 72, heating the liquid and flowing out again to the heater by a tube 26. Gas from the space 76 passes through a sleeve aperture 33 to a tube 32 and through the heater. A tube 180 allows gas produced in the sleeve to flow into the gas space 76. The tubes 26, 32 lead into a regulator, Fig. 2, with an adjustable valve 84, with which the tube 26 connects directly through a restricted passage. 80, while the tube 32 passes'to the valve by lifting a diaphragm 90 when under sufficient pressure. The diaphragm is subjected to an adjustable pressure by a spring and allows a constant pressure difference to be maintained between the gas space 76 and the atmosphere. A gauge and a relief valve are provided for the passage 78 connecting the tube 32 with the diaphragm, which is larger than the restricted passage 80. The tubes 18, 22, 32 are of the lowest possible conductivity, made, e.g., of nickel silver, " Everdur " (3 per cent, silicon, 1 per cent. manganese, 96 per cent. copper) or stainless steel (18 per cent. chromium, 8 per cent. nickel, balance iron). The Specification as open to inspection under Sect. 91 describes apparatus in which the coil 72 lies below the sleeve 66, which is shortened, and also the use of a heating chest in the form of a collar surrounding the neck. This subject-matter does not appear in the Specification as accepted.
