Patent GB-684014-A (GB)
Title: Electric plug sockets
IPC: H01R13/447
Filed: 1951-03-09
Abstract: 684,014. Two-part couplings. OOSTERLING, J., and BOOTSMAN, G. March 9, 1951 [March 11, 1950], No. 5792/51. Class 38(i). A socket has a pair of non-contact containing recesses for receiving the plug pins, and inclined guide tracks for the pins extending upwardly from the base of these recesses to the mouths of the usual contact containing recesses, whereby the plug can be left inserted in the socket without being connected to the supply and moved along the guide tracks to the contact containing recesses to be connected. The socket comprises an insulating base 1 having a pair of blank recesses 14 and contact recesses 5 connected by curved helical grooves 15 having bottoms 16 which rise from the base of a respective recess 14 to the surface of the base 1 adjacent an associated recess 5, Fig. 4 (not shown). A hood 2 secured by screws 3 has slots 29 overlying the grooves 15 and recesses 5, 14, and pivotally supports a cover-plate 4 urged counterclockwise by a spring 35 so that a pair of holes 31 therein overlie the recesses 14. The cover 4 is limited in its rotation to 90 degrees by the ends of an arcuate groove 33 therein engaging a stop 34, and is locked in its spring-urged position by the catch ends 22 of spring members 17 engaging notches 37. Insertion of a plug 40 into the holes 31 and blank recesses 14 displaces the catches 22 to unlock the cover 4. The plug may thus be left disconnected in the socket or rotated clockwise to engage the contacts 8. During rotation the plug pins engage the inclined groove bottoms 16 and the plug is thereby pushed out, but on reaching the recesses 5 it is pushed into the contacts 8; the latter comprise a pair of plates connected by plate spring extensions 9 to a terminal member 10. The inclined grooves 15 make it difficult for a child to reach the contacts 8 by means of a flexible wire inserted in the recesses 14.

Abstract: 124,437. Aktiebolaget Exact. March 16, 1918, [Convention date]. Knobs, attaching; nightlatches.-In a night-latch, the operating spindle 5 rigidly attached to the knob 4 and having wings 8 to engage the bolt-actuating part, is passed through an aperture 2 in the door into the lock-casing, slots being provided in the casing for the passage of the wings 8, and is secured in position by a sleeve 6 mounted thereon and adapted to screw into the aperture 7 of the casing. A rose-plate 10 with teeth 11 adapted to be forced into the woodwork and having a notch engaging a rib 12 on the sleeve prevents the sleeve being unscrewed. According to the Specification as open to inspection under Sect. 91 (3) (a), the rose-plate may have a central recess to strengthen it and prevent it sliding off the sleeve before it is attached to the door. This subject-matter does not appear in the Specification as accepted.

Abstract: 636,712. Centrifugal pumps; gas turbines. NASH ENGINEERING CO. Feb. 27, 1948, No. 6062. Convention date, Sept. 19, 1945. [Classes 110(i) and 110(iii)] [Also in Group XXVII] A fuel supply system for a gas turbine or reciprocating engine comprises a booster pump feeding main and emergency pumps in parallel, the two latter pumps discharging to a fuel feed line. As shown diagrammatically in Fig. 5, a centrifugal booster pump 18 delivers fuel to a main pump 43, which discharges by way of a check valve 44 to a fuel line 45 leading to burner nozzles: The booster pump 18 is also connected to the fuel line 45 by way of an emergency pump 20 of the sliding-vane type and a check valve 56. A valve 55 in a by-pass pipe 54 is normally open, but may be adjusted either manually or automatically to bring the emergency pump 20 into action. A relief valve 100 is provided. As shown in Fig. 3, the booster pump 18 and a liquid-ring pump 19 are directly driven by a motor 17, the emergency pump 20 being driven through gearing 24, 25; the unit is submersed in a fuel tank 10. Any vapour in the fuel entering the impeller 33 of the booster pump 18 collects in annular grooves 60, 61, and passes by way of passages 64-67 to the liquid-ring pump 19. The mixture of air, vapour and fuel discharged at 68 by the pump 19 passes upwardly past gears 24, 25, lubricating them, and then flows through an annular chamber 75, cooling the motor 17 before being discharged at 81.

Abstract: 1365924 Carrier bag handle BRITISH VISQUEEN Ltd 16 Feb 1972 [5 March 1971] 6109/71 Heading G [Also in Divisions B5 and E2] A plastics film article, e.g. a carrier bag or tarpaulin, comprises a sheet 1 having a reinforcing strip 2 of plastics or woven or non- woven fabric adhered to the film with a longitudinal aperture or slit 3 through the strip and film whereby the article may be held by an applied force at the top end of the slit parallel to the slit axis, and a plurality of spaced transverse incisions 4 through the strip and film beyond the bottom end of the slit, increasing in length with distance from the slit and bisected by the slit axis. When e.g. a cord applies a load at the top end of the slit, the tendency to tear the film beyond the bottom 6 of the strip is reduced by the opening up of the incisions 4 and the redirecting of the tearing forces transversely. The aperture 3 may form a bag carrying hand-hole.

Abstract: 1,062,398. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 14, 1966 .[April 28, 1965], No. 6355/66. Heading H1K. A diffusion mask for a body of semi-conductor material comprises an epitaxial layer of a further semi-conductor material. As described, a film of silicon dioxide is deposited on a wafer . of gallium arsenide and is then, by photolithographic methods, removed from the whole surface with the exception of those areas into which diffusion is to take place. The exposed gallium arsenide surface is then covered by an epitaxially-grown layer, about 4 microns thick, of germanium, by means of a disproportionation process. The remaining silicon dioxide film is dissolved away in hydrogen fluoride and zinc is diffused into the gallium arsenide through the apertures in the germanium layer. Alternatively, the silicon dioxide film may be left in place so that the diffusion-occurs mainly at the interface between the silicon dioxide and the germanium. The germanium layer is finally removed by immersion in 30% hydrogen peroxide. A silicon masking layer may be used on a gallium phosphide substrate.

Abstract: 515,615. Discharge lamp. OERENSOFI, N. S. March 5, 1938, No. 6913. [Class 39 (i)] In order to give approximately white light a discharge lamp envelope is divided by a transverse partition into separate chambers filled with gases or vapours giving approximately complementary colours. In the arrangement shown a tube 1 is divided by a transverse partition 2 into a larger chamber 1a containing argon and mercury and a smaller chamber 1b containing neon. The partition 2 is a sheet of tungsten or " Kovar " with a thin edge sealed into a blown-out portion of the tube. The two chambers contain ordinary hot cathode electrodes 3, 4 and the chamber 1a also contains an electrode 5 arranged as described in Specifications 472,648 and 515,419 to emit electrons in the direction of the electrode 3 and canal rays in the direction of the partition 2, which is coated on the side facing the chamber 1b with a substance which becomes emissive when heated by the canal rays. The partition 2 is connected to the source 8 by a lead 2a and a resistance 9 is placed between the partition 2 and electrode 4 which is cut out automatically (by means not shown) when a discharge is set up in the chamber 1b.
