Title: An improved detachable cover or reflector for a lighting fitting
IPC: F21V17/16
Filed: 1948-09-02
Abstract: 644,696. Tubular-lamp fittings. EDISON SWAN ELECTRIC CO., Ltd., and WILMAN, D. Sept. 2, 1948, No. 23160. [Classes 75(ii) and 75(iv)] In a lighting fitting of the type having a trough-like box 2 for ancillary electrical equipment, a framework supporting a reflector 1a or a cover for the fitting is detachably secured to the box 2 by means of catch mechanism 7 provided on one or both of the end members 3, 3a of the framework and adapted to engage complementary members on the box 3. A catch member 9 pivoted on a rod 11 traversing a recess in the end member 3 engages a hook-like member 13 on the end wall of the box 2 and a part 10 of the member 9 extends through an aperture in the end member 3 to serve as a finger-piece whereby on raising the framework 3, 3a bodily the catch member 9 can be rotated clockwise against the action of a torsion spring so that it clears the hook-like member 13 when the framework is lowered. An alternative catch mechanism comprises a stirrup-type catch 16 pivoted to the inside of the end member 3 and urged in an anticlockwise direction by a torsion spring 12, and a complementary hook-like member 13 supported below the end of the box 2. To disengage the parts 13, 16 the framework is raised and a button 18 accessible from the outside of the end member 3 is depressed to displace the stirrup out of alignment with the hook; the framework is then lowered. The hook-like member 13 is provided with a U-shaped knock-out 19<SP>1</SP> which registers with but is smaller than the U-shaped knock-out 19 provided for wiring on the box 2, the securing means for the member 13 comprising a screw 20 and a clamping plate 21. One end of the framework may be hinged to the box 2. The cover carried by the framework may consist of refractor or diffuser members and may include a louvre. Specifications 573,781 and 643,226 are referred to.

Title: Improvements in and connected with lubricant feeding devices and systems
IPC: F16N27/00
Filed: 1936-08-27
Abstract: 480,709. Force - feed lubricating ; syringes. TECALEMIT, Ltd., and LANGLEY, T. W. Aug. 27, 1936, No. 23574. [Class 12 (iii)] [Also in Group XXVIII] In a lubricant-supply system a pump 8 delivers fluid under pressure through a pipe 6 to the space below a piston 12 in a cylinder 2 to discharge lubricant on the other side of the piston through an outlet 13 to the parts to be lubricated. The system may include a number of cylinders 2 and the pump may be electrically driven and of the kind described in Specification 389,717, [Group XXVIII], each pumping unit of which is connected to one of the cylinders 2. When the piston 12 completes its stroke, fluid pressure builds up in the cylinder and a pressure gauge A indicates that it should be recharged with lubricant. Excess fluid pressure is relieved by a safety valve 16a. Each cylinder 2 is connected by a common pipe 10a to an airoperated grease pump 11, and has a screwdown valve 9. To recharge a cylinder, the valve 9 is opened, and the valve 16a is raised by a handle 23 to allow the pressure fluid below the piston 12 to flow back to the feed tank 27 of the pump 8. When the cylinder is recharged, the valves 9, 16a, are closed. The arrangement permits one cylinder 2 of a set to be recharged while the rest are working.

Abstract: 185,420. Ramsay & Moeglen. Sept. 2, 1921, [Convention date]. Milling-cutters.-In a hob for gear-cutting, the thread is divided by an odd number of longitudinal grooves a, and the faces o, p, q of every alternate recess are ground out before tempering to a greater depth than the faces r, s, t of the remaining recesses which alone form with the grooves a the effective cutting-edges. The recesses r, s, t may be finished after tempering by means of a grinding-wheel of large diameter as shown in Fig. 4 without the wheel contacting with adjacent faces o, p, q. Successive cutting teeth round the thread of the hob operate alternately on the right and left, thus facilitating the disengagement of the chip. The bottom .faces s of the teeth serve, in cutting, to true up the periphery of the wheel under operation.

Title: Process and apparatus for discharge of fission gases from nuclear reactor fuel elements
IPC: G21C3/16
Filed: 1965-06-03
Abstract: 1,103,217. Nuclear fuel elements. FUER KERNFORSCHUNG G.m.b.H. 3 June, 1965 [3 June, 1964; 31 Dec., 1964; 26 March, 1965], No. 23758/65. Heading G6C. Fission product gases are discharged from nuclear fuel elements through devices which delay the passage of the gas for at least 10 days in order to allow its radioactivity to decrease, intermixing of newly-formed fission gases with fission gases whose radioactivity has partially died down being prevented. The fuel may comprise UO 2  + PuO 2  and the gas may be discharged into the coolant, for example liquid metal, gas, or steam. An absorption filter arranged between the fuel and the delay device, or in the delay device, serves to absorb or react with volatile condensible fission products such as bromide, iodine, rubidium, and caesium. The fuel element may be filled with an inert gas to prevent entry of coolant. A series of delay chambers may be provided, connected by narrow passages formed electronically or by passages filled with compressed sintered powdered absorbent (Figs. 1-3, not shown). The passage may be in the form of a labyrinth (Fig. 4, not shown). One or more flattened tubular devices may act as excess pressure valves (Figs. 5-7, not shown) so as to prevent escape of fission gases until a predetermined pressure has been reached.
