Patent GB-271506-A (GB)
Abstract: 271,506. Westinghouse Electric & Manufacturing Co., (Assignees of Mc- Culloch, L.). May 20, 1926, [Convention date]. Vacuum tubes.-Alkali metals for use, for example, as photo-electric and thermionic films are introduced into vacuum tubes by introducing trinitrides of the alkali metals with trinitrides of alkaline earth metals and decomposing by heat, the trinitrides of the alkaline earth metals lowering the temperature of decomposition of those of the alkali metals. Caesium trinitrides may be mixed with barium trinitride, caesium being formed by heating to below the softening point of soft glass. Danger of explosion is avoided by adding inert material such as zirconium silicate or silicon dioxide to the mixture, or by distributing the mixture in porous quartz or other coherent material. The walls of the tube may be coated or a photo-electric or thermionic deposit may be formed on an electrode or a deposit may be driven by heat from one electrode to another. After introducing the mixture, the tube is baked at a temperature too low to decompose the nitrides and is exhausted to a pressure of 10<-3> mm. The tube is then heated 'to decompose the nitrides and the nitrogen may be removed. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the introduction of metal such as sodium, potassium, rubidium and caesium by placing the trinitrides on an electrode, heating the tube below 200‹ C. during exhaustion and then decomposing the trinitrides at 200- 500‹ C.: also the use of the introduced metal as a getter absorbing gases directly or on flashing by heating. This subject-matter does not appear in the Specification as accepted.

Abstract: 825,861. Feeding sheets. ROFFEY, W. A., and MOLINS MACHINE CO. Ltd. Sept. 6, 1957 [Sept. 6, 1956], No. 27306/56. Class 100(1) [Also in Group XXIX] In an air pressure regulating device arranged between a source of suction and a suction nozzle or head there is a main chamber 1, an air inlet 4 from the suction nozzle, an air outlet 5 to the suction pump &c., a pressure gauge 25, and a flexible rubber diaphragm 15 covering an opening 14 in the chamber. A piston 6, for controlling the air flow through the outlet 5, is provided with air passage grooves 7, and has a top flange provided with a rubber ring which can engage a seating to cut off the air flow when the piston moves downwardly. The stem 11 of the piston 6 is pivoted to a lever 12 rockable about a pivot 13 and a rod 18 pivoted to the other end of the lever 12 passes through the rubber diaphragm 15 and is screw-threaded to receive a nut 19 which clamps the diaphragm against a shoulder 20 on the rod 18. The diaphragm is clamped to the chamber 1 by a ring 16 and screws 17. An adjusting nut 21 on the rod 18 presses a compression spring 22 against a bridge 23 supported on posts 24 secured to the chamber 1. The spring 22 tends to urge the rod 18 downwardly and thus urges the diaphragm 15 outwardly of the chamber 1. In operation, with the suction nozzle &c. engaging a sheet &c. the air pressure in the chamber 1 is below atmospheric pressure, and the diaphragm 15 will be pulled inwardly against the action of the spring 22. The nut 21 is adjusted so that the pressure in the chamber 1 is at the desired level as shown by the gauge 25. If the internal air pressure falls below the desired level, the diaphragm 15 is pressed inwardly, the rod 18 is moved upwardly, and the piston 6 is lowered to close the outlet 5 until the desired level of internal pressure is again established by air entering through the inlet 4. The inlet 4 can be connected to a sheet-feeding nozzle, and means can be provided for cutting off the air supply after each sheet has been fed. If the nozzle fails to grasp a sheet, there is a sudden substantial increase in the air pressure in the chamber 1, and a temporary sudden and appreciable outward movement of the diaphragm 15 and rod 18; this sudden movement of the rod 18 can be utilized to operate a signal, or actuate mechanism which modifies subsequent operations.
