Title: Improvements in locks for doors, safes and the like
IPC: E05B35/08
Filed: 1938-09-26
Abstract: 505,958. Multiple-key locks. JACKSON, D. S. Sept. 26, 1938, No. 28014. Convention date, Oct. 5, 1937. [Class 44] In a change-key lock, one or more selectors 29 each have an individual locking-lever 33 coupled by turning the key, movement of the selector members in one direction effecting their adjustment and in another direction their coupling. The selectors are mounted on pins 17, 25 carried by the lock-bolt 12 and have teeth 32 for engagement with teeth 34 on the levers 33 which are pivoted on a fixed pin 14. The levers 33 can be moved only when the bolt 12 is shot, and the bolt cannot be retracted until the levers are correctly set, due to the setting of the selectors 29 by the key used to shoot the bolt. The tumbler 19 is mounted on pin 14 and has slots to pass the pins 17, 25 and a notch 27 for the bolt-tongue 28. The tumbler and selectors are engaged by individual spring-pressed fingers 21.

Title: Improvements in or relating to electric capacitors
IPC: H01G2/08
Filed: 1952-11-07
Abstract: 749,438. Capacitors. SIEMENS & HALSKE AKT.-GES. Nov. 7, 1952 [Nov. 14, 1951], No. 28146/52. Class 37. In a roll-type capacitor, each electrode is in contact with a metal layer extending at rightangles to the roll axis, and a cooling medium is circulated over an extended length through a device which is mechanically connected to the layer. The length is at least equal to the periphery of the layer. Figs. 1 and 2 show a rolled capacitor 1 comprising foils 13 and 14 which are in contact with metal layers 3 and 2 respectively. Metal tubes 4 and 12 in the form of cooling tubes are placed on or in the metal layers 3 and 2 and constitute the connecting leads to the capacitor, connections being made to metal bars 7, each of which is in contact with one of the tubes 4 or 12. A non-conducting cooling fluid is preferably used, and insulating portions 9 may be provided to isolate the connections from the rest of the fluid flow system. The tubes may be spiral in form, the cooling fluid entering at the centre of the spiral to increase the cooling at the central portion of the capacitor, which may comprise a ceramic core, which projects to form a centre for the tube spiral assembly. Cooling is facilitated by making the diameter of the roll large relative to its length. The tubes may be silver-plated, and may be soldered in place after formation of the metal layer; alternatively the layer may consist of tin which is melted when the tubes, previously heated, are applied to the layer. The dielectric material may consist of polystyrene.

The mixers a, c are connected by pipes d, f to a suction inlet g of a grinder b. A discharge pipe h from the grinder communicates with the mixers through pipes k, l. When material from the mixer a is to be discharged into the mixer c the valves o and n are opened and the valves m and p closed. The material then passes through pipes d, g, grinder band pipes h, l to the mixer c. When this action is complete the open valves are closed and the closed valves are opened to reverse the process.

Abstract: 1,066,179. Welding by pressure. AMERICAN MACHINE & FOUNDRY CO. July 10, 1964 [July 10, 1963], No. 28562/64. Heading B3R. In friction welding an aluminium or aluminium alloy workpiece and a copper workpiece the workpieces are relatively rotated and forced together so that at least 3000 foot pounds of energy are released in the weld area per square inch of weld area and so that the relative rotation is stopped in less than 10 seconds. A copper workpiece (10), Fig. 1 (not shown), is fixed in a stationary chuck (11) on a plate (12) movable by hydraulic cylinders (17) and an aluminium workpiece (13) is mounted in a chuck (14) fixed to a shaft (15) carrying a flywheel (19) rotatable by a motor (20) through a clutch (21). The energy input may be 3000 to 30,000 foot pounds per square inch of weld area for areas of 0À01-10 square inches and the energy should preferably be delivered in two or less seconds. For the workpieces (10, (13) the energy is 6500 foot pounds per square inch but for stud to plate welding two or three times this energy is required. The workpieces are pressed together with a pressure of 5,000 to 30,000 pounds per square inch of weld area. Tubing may be welded.

Abstract: 1430171 Internal shoe drum brakes; slack-adjusters GIRLING Ltd 24 May 1974 [16 June 1973] 28723/73 Heading F2E An internal shoe drum brake of the kind in which arcuate shoes carrying friction linings are adapted to be separated at one pair of adjacent ends by an actuator which includes a pair of separable tappets acting on the ends of the shoes, and an adjuster, with which the opposite or non-actuated shoe ends engage, is adapted to adjust the spacing between the latter ends to compensate for lining wear, further incorporates transmission means for operating the adjuster, the transmission means being arranged to sense relative movement between the tappets in the application of the brake. As shown in Figs. 1 to 3, but without reference to components 44 to 46 (see later), brake actuation by a rotary cam 9 on the end of a shaft 10, Fig. 2, results in a cable 36, fastened to tappet 6, Fig. 1, being pulled further through a easing 37, fastened to tappet 7, this movement resulting in a drum 28, Figs. 1, 2, around which one turn of cable 36 is secured at one point 40, being rotated through a small angle. A clutch plate 29, Fig. 2, has one-way teeth in one face inter-engaging one-way teeth in an adjacent face of the drum, and is urged against the drum by a blade spring 31 backed by a cap 32 and compression spring 33. On brake release, the cable and drum are returned to their former positions by a spring 43, Fig. 1, and if lining wear was excessive drum 28 will have jumped over one tooth of clutch plate 29, during application, so the clutch plate will be rotated slightly on this release movement. The clutch plate is keyed to a worm 25 which meshes with teeth 26 on a sleeve 16, Fig. 3, the sleeve having threaded parts which cause outward movement of further, adjuster, tappets 22, 23 on such worm rotation. Where a second spring 44, Fig. 1, operative between the end of casing 37 and tappet 7 is provided, the teeth on drum 28 and plate 29 are reversed in sense, and wear adjustment takes place at the brake-application phase; with low loading in the screw threads. Blade spring 31 may be replaced by a compression spring. Several modes of connection of cable 36 and casing 37 (in the absence of spring 44, &c.) with tappets 6, 7, respectively, are described (Figs. 7 to 13, not shown). Adjustment may be effected by a screwdriver inserted in a slot 27, Fig. 2, provided in one end of the worm 25.

Patent GB-654672-A (GB)
Title: Method of refining steel
IPC: C21C7/064
Filed: 1947-10-28
Abstract: A method of dephosphorizing steel having an initial phosphorus content of about 0.06 per cent, as obtained in a basic Bessemer converter, and reducing impurities therein, in which the steel in molten state is treated with solid caustic soda while it is flowing from the converter, or from a ladle into which it is charged from the converter, into another vessel or into a refining furnace.  The caustic soda, which may be in flake form, may be blown into a jet of the molten steel and 1.5-3 per cent of the reagent may be used based on the weight of steel.  In applying the invention the converter may have mounted on it a conduit provided with two pressure air inlets and terminating under the throat of the converter in a flat spout or nozzle.  The conduit is provided with a charging hopper into which the caustic soda used in the refining operation is charged.  The Specification as open to inspection under Sect. 91 comprises also the refining of metals and alloys by use of an alkali or alkaline earth material or mixture of such, or material adapted to supply a strong alkali, the material being added alone or mixed with other materials. The removal of silicon, sulphur, manganese and carbon impurities is referred to.  Ferro-alloy, haematite cast iron and acid Bessemer steels may be so treated.  Apparatus for carrying out the process comprises a combination of a pipe and a charging hopper into which the alkali reagent is placed.  The pipe terminates in a frusto-conical spout or nozzle and is connected at its other end through a union member to a compressed air supply.  Compressed air passing through the pipe carries with it the reagent from the hopper and discharges it through the nozzle into the molten metal as it is being poured.  The apparatus may be mounted on a movable carriage, or in a modified form it is mounted on a converter with the pipe terminating in a flat spout under the throat of the converter.  This subject-matter does not appear in the Specification as accepted.
