Title: Improvements in and relating to electrical brush holders
Inventor: KING FREDERICK HERBERT GEORGE
IPC: H01R39/38
Filed: 1964-10-22
Abstract: 1,125,131. Brush holder for dynamo-electric machines. MORGAN COMPONENTS Ltd. 14 Oct., 1965 [22 Oct., 1964], No. 43139/64. Heading H2A. In a brush holder for a dynamo-electric machine having a lever arm 4 pivoted within an open-topped box or hull 1 and loaded by at least one compression spring 10 which is wholly accommodated within the open-topped box 1 so as to be shrouded against flash-over from adjacent live components of the machines, the arrangement of the, or each, spring is such that the movement arm of the force applied by the spring about the lever arm pivot 7 increases as the spring extends to give a constant loading to a brush mounted in guide 2, 3 of the holder. As shown, the brass brush holder 1 has a pressure finger 5 with an insulating tip 6 attached to a saddle lever arm 4 supported on nylon bushes 8 on spindle 7. The compression springs 10 (and 9, see Fig. 2, not shown), are arranged to bias the lever arm either side of a dead centre position, either against a back stop provided by the casing 1, for removal of the brushes or into engagement with the brushes as shown dotted. Within the saddle 4 is a similar lever arrangement 13 loaded by a compression spring (15, Fig. 2, not shown), which has the same loading effect as the combination of the springs 9 (and 10). Movement of the pressure fingers into the brush guides 2, 3 is limited by stops 16, 17. The springs slide on nylon cores (18, 19, Fig. 3, not shown) which provide a damping action. The brushes may be single or a pack of carbon blocks.

Title: Lapping device
IPC: B24B35/00
Filed: 1966-09-28
Abstract: 1,133,884. Grinding. KLÍCKNER-HUMBOLDT-DEUTZ. 28 Sept., 1966 [23 Oct., 1965], No. 43297/66. Heading B3D. A device for lapping the root profile 12 on turbine or compressor blade 4 in a rotor disc 1 with a vertical lapping movement comprises a part 3 for clamping to the root of the blade connected by a vertically swingable parallel linkage 5, 6 to a horizontally slidable rod 11 loaded by a tension spring 10, the axis of the rod, when viewed vertically extending centrally through the blade root, the axis X-X of the linkage on the clamping part being below the centre line of the blade root so that the tilting movement caused by the weight of the blade is eliminated by the movement caused by the tension of the rod acting on the said axis X-X of the linkage, and a pair of pins 17, 18 which rub on the end faces of the root of the blade to impart the lapping movement to the blade. The rotor disc has shaped sockets 2 for receiving the roots 12 of the blades, and the part 3 of the device is clamped to the root of the blade to be lapped. The links 4, 5 have an annular knife edge connection with a pivot in the part 3, and the other ends of the links have an annular knife edge connection with a pin 7. The rod 11 has an annular knife connection with a selected one of three grooves 14, 15, 16 in the pin 7 and is acted upon by a spring 10, the tension of which is adjustable by a cam 13. The axis of the pivot on the clamping part 3 is a distance a below the horizontal centre line of the blade to produce an upward movement acting on the blade in opposition to the downward movement produced by the weight of the blade. The lapping movement is imparted to the blade by a pair of thrust pins 17, 18 acting on the end faces of the root of the blade. When the annular knife-edge 8 of rod 11 engages the centre groove 16 on the pin 2, the blade has only radial play with respect to the rotor disc after lapping. If the edge is engaged first in groove 14 and then groove 15, the blade can move after lapping at right-angles to the direction of the lapping movement.

Abstract: 436,797. Walls; floors; slabs. CARSON, N. B., and GILLIES, M. C., 214, West Regent Street, Glasgow. April 17, 1934, No. 11507. [Classes 20 (iv) and 87 (i)] The exterior surface of the hollow wall of a building is formed of pre-cast reinforced concrete blocks E which are of channel shape in horizontal cross-section and are arranged side by side and in vertical rows with the flanges of the successive blocks in such vertical rows in line so as to form interior vertical buttresses, and the blocks are bonded together at various levels, as shown in Fig. 4, by pre-cast reinforced concrete beams F of substantially channel cross-section, which are adapted to bridge at least two joints between adjacent blocks E and are arranged with the flanges extending horizontally inward from the vertically disposed web. All the elements are secured together by cement and without in-situ casting, although a reinforced concrete stud may be cast in situ at the corners of the building. The height of the blocks is such that a substantial number thereof must be superimposed to attain storey height. The blocks E may have interengaging projections and recesses 13a as shown in Fig. 1<a> and be built up in two opposed layers to form a double wall. Alternatively, the wall may consist of an outer surface of blocks E and an inner surface formed either of breeze blocks or of wallboards secured to timbering which is separated from the blocks E by felt pads. At corners, a reinforced concrete stud 36, Fig. 6, may be cast, or disposed in pre-cast form, between the adjacent flanges of the blocks E, or the corner stud may be of pre-cast L- section. The wall beams F are preferably arranged at floor and ceiling levels and may have, as shown in Fig. 2, an ornamental bead 21 and a ledge 22 to provide a recess for the reception of a window or door frame 26. The floor beams G, which are of reinforced concrete and of inverted T-section, are supported at ground level either on a double set of blocks E, as shown in horizontal cross-section in Fig. 7, or on a wall beam F of inverted channel section as shown in Fig. 9. The wooden floor joists 46, which are arranged at right angles to, and are carried by, the ground floor beams G, extend at their ends into spaces provided between the short blocks E of the inner surface of the side wall as shown in Fig. 9<c>. As shown in Fig. 9, the width of the hollow wall in successive storeys is decreased, the wall in the first two storeys being formed of two opposed layers of blocks E, and the uppermost storey being provided with an inner surface of breeze blocks or wallboards. The blocks E, and wall and floor beams F, G are formed of concrete reinforced by longitudinal rods connected by stirrups. The flanges of the channel blocks and wall beams may be apertured to facilitate air circulation. The Provisional Specification describes also the blocks as being of shallow open box form, and the association with the U -section bonding beam of an abutting beam of L-section.

Title: Refrigerator
IPC: F25D17/04
Filed: 1961-12-06
Abstract: 926,256. Valves. GENERAL MOTORS CORPORATION. Dec. 6, 1961 [Dec. 13, 1960], No. 43680/61. Class 135. [Also in Group XIII] In a refrigerator in which a compartment is cooled by air circulated past an evaporator and through the compartment, the rate of air flow is variable by a valve the position of which is controlled by an electric circuit which includes a thermo-responsive device located in the compartment. As shown, a duct 62 has a valve 64 to control the air flow therethrough, the valve being hinged by a bi-metallic strip 66, Fig. 2, controlled by a heater 78 so as to open the valve as the temperature of the heater rises. The valve is connected at one end to an adjustable arm assembly 68 which permits the initial opening of the valve to be set. Two thermistors 80, 82 are connected in parallel and situated as shown, are connected in series with the heater 78 so that as the temperature rises in the compartment their resistance decreases and results in an increase in the current flowing through the heater 78. An adjustable resistance may be placed in series with the heater to allow for further adjustments of the valve. In a modification the bi-metallic strip is selfheating and zig-zag in form. Further modifications involve the use of thermistors with positive temperature co-efficient of resistance, the use of more than two thermistors or the use of a tensioned wire through which the electric current passes in place of the bimetallic strip.

Abstract: 1,017,154. Laminates and laminating. UNIVERSAL LEATHER GOODS CO. Ltd. Oct. 29, 1963 [Nov. 22, 1962], No. 44111/62. Heading B5N. Laminates comprising two layers of plastics material, one of which is an expanded material are produced by heating a first layer to a welding temperature and uniting it with an expanded layer in the nip between a pair of rollers, said expanded layer being pre-heated on its contacting surface and being produced by continuous casting. In the embodiment of Fig. 2 (not shown), expanded plastics material, e.g. p.v.c., is produced by coating a paper carrier 28 with foamable resin at 32, passing it through a hotair oven 36, cooling it at 38, 39 and separating the expanded product from the carrier. Optionally, the carrier may first be coated at 29 with a layer of plastics material compatible with the other layer of the laminate.- The expanded material is mounted at 21 (Fig. 1), and passes via an infra-red heater 20 to the nip formed by rollers 22, 23, the former of which may be an embossing roller the latter being water-cooled and rubber-covered, where it contacts a layer 12, e.g. of transparent p.v.c., which has been printed by rollers 13, 14 and heated to welding temperature by infra-red heater 18. The heat of layer 12 causes fusion of that layer with the surface of the expanded layer and the product is cooled by rollers 25, 26 and wound up. Optionally, an interlayer of woven open-mesh fabric or non-woven nylon or polyethylene terephthalate fibres may be fed to the rollers 22, 23 or introduced between the expanded layer and its skin on the carrier. Further laminates may be produced by welding the finished product 40 to a similar material. The casting process may be continuous with the welding process.
