Title: Production of pellets of thermoplastic material
Inventor: STANLEY THOMAS ALFRED
IPC: B26D1/38
Filed: 1955-06-17
Abstract: 802,160. Making pellets of thermoplastic materials. IMPERIAL CHEMICAL INDUSTRIES, Ltd. May 22, 1956 [June 17, 1955], No. 17513/55. Class 87(2). Thermoplastic rod is extruded, then stretched to such a degree that its cross-sectional area is reduced to one-fifth or less of its original crosssection, and then cut into short lengths to form pellets. A plurality of rods may be extruded, stretched and cut. The drawing shows rod 1 extruded from an orifice 2 and passing through a cooling bath 9 and pulling-rollers 7 to a cutter 8. The orifice 2 communicates with a mixer of the kind described in Specification 626,067 [Group II] which discharges a product having concertina-like variations in diameter.

Title: Improvements in or relating to electrically insulating bodies
IPC: H01B3/00
Filed: 1938-06-14
Abstract: 515,891. Electric insulating bushings. REYROLLE & CO., Ltd., A., KIRKWOOD, I. W. A., and RITCHIE, P. D. June 14, 1938, No. 17606. [Class 36] An electrically insulating bushing, incorporating at least one conducting stress-grading foil or layer, is formed by arranging the conducting layer or layers between wrapped, wound or packed layers of a non-hygroscopic organic substance free from cellulosic or other natural hygroscopic fibrous material and constituting a preliminary support, the interstices of the support being then filled with a polymerisable substance in liquid or semi-liquid form and the whole subjected to polymerisation treatment to form a homogeneous insulating mass. The filling may be the monomer of the substance of the support, or a partially polymerised liquid, or a solution of a polymer in its parent monomer. The support may be of polystyrene, polyvinyl acetate, or acetal, or polymethyl methacrylate, or of two or more materials such as co-polymerised styrene and vinyl acetate, or vinyl chloride and vinyl acetate, or it may be built from a number of polymers of different electric characteristics. A textile of polystyrene fibres' may be wound round a former or conductor, the conducting foil or foils inserted between successive turns, and the support so formed be impregnated with monomeric styrene, preferably in vacuo, and the whole subjected to polymerisation, under pressure if desired. A final treatment to pressure or heat or both may be applied to determine the shape of the bushing.

Title: Improvements in Machines for Manufacture of Single-wire Barbed Wire.
Inventor: HANSEN HANS CLAUSSON
IPC: B21F25/00
Filed: 1919-07-16
Abstract: 129,991. Hansen, H. C. July 15, 1918, [Convention date]. Making barbed wire; corrugating; twisting wires together.-In a machine for making single strand barbed wire the die which produces the bends, around which the barb wires are wound, also feeds the strand. The strand 11 passes from a drum 2 and straightening rolls 3 through slits in blocks 7, 22 having dies 14, 26 reciprocated by springs 13, 25 and cams 16, 28 acting through levers 15, 27. After the die 14 has formed a bend in the strand, the block 7 is moved to the right by a cam 17, thus feeding the strand. The die 26 is then moved down to engage a previously formed bend and hold the strand while the die 14 rises and the block 7 is returned by the spring 19. The transverse wires to form the barbs are cut off and twisted around the strand, while stationary, by known mechanism 29. By altering the cams 16, 17, 28 the spacing of the bends may be varied.

Title: Improvements in or relating to single-phase electric motors and control means therefor
IPC: H02P1/44
Filed: 1956-06-08
Abstract: 794,082. Control of A.C. motors. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. June 8, 1956 [June 14, 1955], No. 17767/56. Class 38 (3). A single-phase motor 15 is started by depressing a push-button 53 to energize the operating coil 28 of a contactor 23, whereby main and auxiliary motor-windings 16, 19, are connected in series across the supply lines, with a capacitor 42 in shunt with the auxiliary winding 19. Closure of the starting contactor 23 connects the coil of a relay 37 across the main winding 16, so that the relay is operated when the speed of the motor reaches a predetermined value. Such operation de-energizes the starting contactor and energizes a running contactor 24 so connecting the main winding 16 directly across the line, and connecting the winding 19 across the line in series with capacitor 43. The motor is protected against both running and starting overloads by means of thermal relays 45, 46, having contacts adapted to de-energize contactors 23, 24, and relay 37. The relay 46 is responsive to the current in starting capacitor 42 which is not in circuit during the running period. The relay 45 responds to the main winding current and is not effective during starting because it has a longer tripping-time than the relay 46. The capacitors 42, 43 are disconnected from the motor when their associated contactors are open, so preventing self-excitation of the motor and undesirable regenerative braking action. In another arrangement, the capacitor which is connected in series with the auxiliary winding during the running operation, is connected across both windings during starting.

Abstract: 1,023,326. Rotary drum filters for liquids. METALLDUK A.B. April 29, 1964 [May 6, 1963], No. 17791/64. Heading B1D. [Also in Division D2] A method of fixing a cloth 2 to the outer surface of a cylinder 1 of a filter comprises driving a nail, screw or like member 8 through the overlapped ends of the cloth into a plug member 4 which is preferably of nylon, mounted in a hole 3 in the casing 1 of the cylinder. The outer end of the plug is flanged, and the inner end is slit and adapted to expand when the nail 8 is inserted, thus gripping the walls of the hole 3. The cloth, which may be of stainless steel or phosphor bronze mesh or of synthetic fibre material is normally fixed to a series of such holes spaced in an axial direction on the surface of the cylinder. In an alternative arrangement both the plug and nail pass through the two layers of cloth. In the application of the invention to a wire wound cylinder the interspaces between the wires and bars of the surface of the cylinder are used for supporting the plug member, which is then of rectangular cross-section.

[Classes 18 and 125 (iii).] A measuring chamber 5 opening into the interior of the bottle or other receptacle 1 has a pivoted cover 10 connected with a valve 12 at the inner end of the chamber so that when the cover is fully open the valve is closed and a measured quantity is delivered, the parts being adapted to be held in an intermediate position to allow of a continuous flow. A cap 3 is threaded on the neck of the receptacle 1 and carries by lugs 6 a spindle 18 for the cover 10 which is extended to form a handle 7 and maintained closed by a spring 8. A rod 11 on the cover carries the valve 12 adapted to close the inner opening 4 of the measuring chamber 5 when the cover is fully opened. The spindle 18 passes through an elongated slot in the lever 7 so that the cover can be slid by pressure upon a projection 24 into the position shown in dotted lines to leave a slot 25 through which the powder &c. may be sprinkled. A stop 21 on the lever 7 co-operates with the end 20 of the spring to hold the cover in the position for sprinkling. An arm 23 projects from the valve 12 to prevent sticking of the powder in the receptacle. An auxiliary handle 9a is provided for use when the receptacle is fixed to a wall. The valve may be made elastic or sharp edged to avoid jamming. Fig. 4 shows a modification in which the rod 11 on the cover carries midway of its length an additional valve plate 14 adapted to coact with a seating 4 between two measuring chambers 5, 15, and the lever 7 is mounted in a member 22 of U-section. In the position of rest shown the powder fills both measuring chambers ; movement of the lever 9 to register with the end of the member 22 closes the valve 14 and delivers the contents of chamber 5, while further movement of the lever 9 into the member 22 by pressure at 17 closes the valve 12 on a seating 13 and delivers the contents of chamber 15.
