Abstract: 683,611. Discharge apparatus. STANDARD TELEPHONES & CABLES, Ltd. Nov. 19, 1948, No. 30087/48. Class 39(i) [Also in Group XL(c)] The trigger electrode of a cold cathode triggered anode gasfilled glow discharge tube surrounds the anode so as to screen the same from the electric field of the cathode in the absence of discharge between the trigger and anode electrode, thus enabling the tube to be connected in a circuit arrangement (see Group XL(c) ) wherein the supply voltage is greater than the anode-cathode breakdown potential. The tube shown comprises a glass envelope 1 having presses 2 and 3 at either end. The trigger electrode 8 is in the shape of a truncated cone surrounding the anode 7 and has a cylindrical portion 12 with projecting flanges 13 and 14 welded to support rods 9 and 10, located by a mica spacer 11. The cathode 4, which may have an activated coating, is mounted on leads 5 located by a mica spacer 6, and is concavely shaped to concentrate the discharge therefrom within the trigger cone. The tube is suitable for direct connection in the wiring of a circuit without using a valve socket. In a modified form, adapted for use with a conventional valve socket, the anode, cathode and trigger electrode are all mounted on one press, and the envelope is fitted with an ordinary valve base. Typical characteristics and dimensions are given.

Filed: 1939-11-23
Abstract: 589,124. Separating gases by liquefaction; mixing gases. SOC. L'AIR LIQUIDE, SOC. ANON. POUR L'ETUDE ET L'EXPLOITATION DES PROCEDES G. CLAUDE. Nov. 23, 1939, No. 30676. Convention date, July 19, 1939. [Class 8 (ii)] Hydrogen or other gas is separated by liquefaction from coke oven gas or other gaseous mixture and mixed with a second cooled gas, e.g., nitrogen, the less volatile gas being taken in the liquid state and in such quantity and at such low temperature that the mixture thus obtained is not wholly vaporized: the mixture cools the gases to be cooled, e.g., the coke oven gas. A cooling section of a rectifying column comprises vertical pipes S, surmounts a washing section P and leads to a second washing section A. Gas from this top section is mixed with liquid nitrogen and passed round the pipes S as washing liquid after having cooled another portion of liquid nitrogen in a heat exchanger M and having been subsequently led through an expansion valve R and a pipe K. The nitrogen is liquefied by cooling compressed nitrogen by separation products, e.g., the liquid mixture of carbon monoxide and nitrogen or the gaseous mixture of nitrogen and hydrogen, the latter mixture being first warmed. The process may be used to obtain a mixture of hydrogen and carbon monoxide. The Specification as open to inspection under Sect. 91 describes a construction in which gas rising from the top of a rectification column A, Fig. 1 (Cancelled) treating coke oven gas flows to a cooled nest of Field tubes C, condensate formed flowing back to the column while the gaseous nitrogen-hydrogen mixture is led to an expansion motor F and afterwards mixed with liquid nitrogen from an expansion valve T, the mixture flowing around the Field tubes to an outlet H. This subject-matter does not appear in the Specification as accepted.
