Title: Horseshoes
IPC: B21K15/02
Filed: 1973-07-31
Abstract: 1442456 Making horseshoes; forging; rolling V S WOOD 19 June 1974 [31 July 1973] 36344/73 Headings B3A B3H and B3M A method of forming a clip on a metal horseshoe 4 comprises locating a horseshoe on a bed 1 having a support surface 6, clamping the horseshoe to the bed, punching the horseshoe to produce a gob of metal (5A), Fig. 3 (not shown), extending from the horseshoe and, rolling the gob against a tapering notch (7), Fig. 3, provided in the surface 6 to complete formation of the clip. When the horseshoe is in position on the bed 1, a framework 22 is pivoted downwardly and a punch 26 on a fixed roller 24 shapes the gob of metal (5A) while a spring 38 drives a clamping plate 12 on to the horseshoe. When the punch reaches the level of the bottom of the fullering groove of the shoe, a projection 36 engages a stop 37 whereupon a trip mechanism 28 releases a lever 27. When the lever is released the roller 24, to which it is secured, is free to rotate and shape the clip in the notch (7). The spring 38 then returns the frame 22 to its original position thereby releasing the clipped horseshoe. The apparatus may be provided with two punches and rollers to form two clips necessary for a rear horseshoe.

Title: Magnetic core data storage and transfer circuit
IPC: G11C19/06
Filed: 1962-09-25
Abstract: 940,830. Magnetic storage devices. AMP Inc. Sept. 25, 1962 [Oct. 11, 1961], No. 36359/62. Heading H3B. In a shifting register in which the inlet and outlet minor apertures 3, 4 and 7, 8 of magnetic storage cores 1, 2 are coupled by transfer windings 11, 12, 13, and in which advance windings 9, 10 are threaded through the major central apertures 5, 6 and a priming winding 14 passes through the outlet apertures, each transfer winding is associated with a respective auxiliary core 15, 16 which is also threaded by the priming winding and functions to suppress spurious outputs when a storage core in the clear or zero state is magnetized by advance pulses. In operation, the priming winding is energized by priming current in the reverse direction to, and before the application of, advance winding current and consequentially sets the auxiliary cores to one magnetic state. The advance winding current passes through the priming winding in addition to an advance winding 9 or 10 and resets the auxiliary cores to the other magnetic state. Each auxiliary core therefore induces a pulse in its associated transfer winding of such polarity as to suppress spurious outputs from the register cores. The auxiliary cores may be made of the same material as the cores 1, 2 and may have substantially the same dimensions as that of the legs of apertures 7 and 8. Specification 899,366 is referred to.

Abstract: 1484477 Tyre building machine GENERAL TIRE & RUBBER CO 19 Aug 1974 [17 Sept 1973] 36478/74 Heading B7C A tyre building machine comprising a radially expansible drum 10 and a transfer ring 53 for transporting a tread and belt assembly 52 is provided with two annular guide members 58, 59 for guiding a carcass 57, built up on the drum 10, during its expansion into engagement with the tread and belt assembly, each guide member comprising flexible helical springs 63 mounted on supports 64, with the helix axes of the springs extending circumferentially of the guide member so that the springs can rotate during carcass expansion. As illustrated, the annular guide members are each mounted on a bead ring carrier 21, 22 and the machine includes end drum assemblies 12, 13 incorporating carcass turn-up bags (not shown). In an alternative arrangement the members are carried by the transfer ring. A tyre is manufactured, using the illustrated machine, by applying parallel cord carcass plies (e.g. radial plies) to the drum 10, inflating bags 20 to expand the drum 10 to form shoulders, moving the carriers to apply bead rings to the shoulders, moving the carriers away from the drum 10, inflating the carcass turn-up bags, moving the carriers inwardly, and deflating the bags, to assist in the carcass turn-up, moving the carriers axially outwardly, stitching the turn-ups, applying other components, e.g. sidewall rubbers and chafer strips, pivoting the carrier 22 to a horizontal position by means of cylinder 38 to permit transfer ring 53 to be moved to the position of Fig. 2, restoring carriers 21, 22 to the position of Fig. 2, inflating the annular bag 19 to bring the beads 72, 73 axially inwardly of elements 77, inflating bags 20 and subsequently axially contracting the drum 10. Stitching of the tread and belt assembly is effected after axial removal of the transfer ring. The tyre is then removed after collapse of drum 10 and removal of carrier 22 to its horizontal position. The specification also discloses a method of manufacturing a tyre, using the same machine, in which the beads remain axially outwardly of the elements 77 (Figs. 6-8, not shown).

Title: Method for preparing laminated article of metallic polymeric  and wax impregnated cellulosic layers
IPC: B32B15/10
Filed: 1971-08-03
Abstract: 1357972 Laminates SUN OIL CO 3 Aug 1971 [6 Aug 1970] 36495/71 Heading B5N A three-layer laminate having an outer waximpregnated cellulosic layer, a middle thermoplastic polymeric layer and an outer metallic layer is made by (a) forming a heterogeneous dispersion of a finely divided thermoplastic polymer and molten wax, which polymer has an adhesive capacity for both the metallic and cellulosic materials and a melting point above the melting point of the wax and is substantially insoluble in the molten wax at a temperature below the melting point of the polymer; (b) applying a coating of the heterogeneous dispersion to an inner surface of at least one of the outer layers at a temperature above the melting point of the wax but below the melting point of the polymer, the amount of the coating being such that substantially all of the wax therein is absorbable in the cellulosic layer; (c) placing the other outer layer adjacent to the coating; (d) heating the coating to a temperature above the melting point of the polymer and pressing the outer layers against the coating whereby the molten wax is absorbed into the porous cellulosic layer and a substantially continuous molten polymer layer is formed between the metallic layer and the impregnated cellulosic layer, and (e) thereafter cooling the molten polymer until it solidifies to give the three-layer laminate. The cellulosic layer may be of paper or cardboard and the metallic layer may be made from aluminium, steel, tin, lead, silver, gold or a tin-lead alloy. The heterogeneous dispersion suitably contains from 5 to 45 parts by weight of polymer and 95 to 55 parts by weight of wax: Suitable polymers are polyamides, polyvinyl chloride, cellulose acetate butyrate, polymethyl methacrylate, polyethylene with a molecular weight in excess of 1,000,000, a polycarbonate or polystyrene. The wax is preferably a petroleum wax. The dispersion may be applied to either the cellulosic layer or the metal layer or both layers may be coated before being brought into contact. In a preferred embodiment a heterogeneous dispersion 4 maintained at a temperature above the melting point of the wax is transferred to between a cellulosic layer 5 and a metallic layer 6. The layers then pass between rolls 7 and 8 heated to a temperature above the melting point of the wax. These rolls may be at the same or different temperatures. Afterwards the laminate is cooled by cold rolls 9 and 10 thereby causing the molten polymer to solidify. The laminate may be used as a packaging material.

Abstract: 1277115 Knitting COURTAULDS Ltd 21 July 1969 [22 July 1968] 36540/69 Headings D1C and D1K In knitting a sleeved garment, the body portion 1 is commenced at the lower end and its top portion 6 is joined to the shoulder portions 4, 5 during knitting. The body and sleeve portions are knit up to the armpit region on a flat machine having at least one pair of opposed beds. The sleeves may be knitted on pairs of beds movable relative to the body beds. Thereafter the upper body portion is knit followed by the shoulders or vice versa, the parts being joined by stitch transfer as knitting of the later part proceeds. The shoulders are knitted by reciprocation so that pieces on the two beds are joined at the outermost edge. One shoulder portion may be knitted before the other. Alternatively the top body and shoulder portions may be knitted contemporaneously. To prevent the sleeve beds clashing as they move inwards to transfer loops their end portions may be removed, or the stitches moved inwards so that the beds can be moved outwards.

Abstract: 1,202,231. Treating crimped yarns. LEESONA CORP. 9 Aug., 1967 [31 Aug., 1966], No. 36561/67. Headings D1F and D1W. A false-twist crimped yarn is overfed to a package such that its length on the package is at least 40% greater than its totally released length but not more than a third of its original length. Yarns may thus be wound on a false twist crimping machine having the take-up packages disposed above or below the falsetwist spindles through which the yarns pass vertically upwards, a shield being provided between the spindles and the yarn path down to the lower take-up packages. Alternatively, the yarns may be wound on a separate machine having a heater plate between the yarn feed rolls and the take-up packages. To avoid "high end" formation on the take-up package due to the low yarn tension the traversing guide is reciprocated through a device which scatters the mid-points of successive reciprocations. A static eliminator which produces a field of ionized air or which contacts the yarn may be provided adjacent the rolls which feed the yarn to the take-up package. The yarn may be composed of nylon, a polyester or a polyolefine.

Title: Improvements in and relating to a method of and apparatus for soldering printed circuits
Inventor: ROSE DENNIS
IPC: B23K3/06
Filed: 1955-12-21
Abstract: 798,454. Soldering. ULTRA ELECTRIC, Ltd. Dec. 21, 1956 [Dec. 21, 1955; March 9, 1956], Nos. 36679/55 and 7411/56. Class 83 (4). In soldering connections from components on one side of a board to printed circuits on the other side of the board, the board is moved across a jet of solder impinging on its undersurface through which the connections protrude, the jet being elongated in a direction at right angles to the direction of movement. In an embodiment, a vertical duct 2 is fixed inside a solder bath 1 so that the upper end of the duct is just above the solder surface and a centrifugal pump 3 connected to its lower end delivers solder up the duct forming an elongated jet 5. The circuit board is guided transversely to the duct so that the jet impinges on the printed circuits on the lower surface of the board. In a modification, the upper end of the duct is shaped to direct the solder jet 15 in a direction opposed to that of the circuit board movement. In this case the board may be inclined to the horizontal.

Title: Improvements in or relating to magnetic information storage devices
Inventor: BREWSTER ARTHUR EDWARD
IPC: H03M7/16
Filed: 1958-11-14
Abstract: 840,023. Circuits employing bi-stable magnetic elements. STANDARD TELEPHONES & CABLES Ltd. Nov. 14, 1958, No. 36705/58. Class 40 (9). [Also in Group XL (c)] Two similar magnetic cores 1, 2 having rectangular hysteresis characteristics have a triggering pulse from a further core 11 applied to their windings 3, 4, the pulse being of such amplitude and duration that only one of the cores is able to reverse its magnetization. Both cores are biased in opposite senses by windings 7 and 8, while core 1 has an input winding 5 which is wound in opposition to the trigger and bias windings on that core. An input pulse from a source 17 is applied to core 1 at the same time as the triggering pulse, and if this pulse exceeds a certain threshold value core 2 is reversed by the triggering pulse and a positive pulse is supplied by an output winding 10 to a gate 24. If the input pulse is below the threshold value or is absent, core 1 is reversed by the combined effect of the triggering pulse and the bias, and a negative pulse is supplied by an output winding 9. The core 11 is sequentially reversed by a sine wave current from source 16 in a winding 12, this source also controlling the gate 24 so that spurious outputs due to restoration of core 11 to its initial state are cut-off from output 23. Modifications are described in which the bias winding 8 is omitted or an additional input winding is provided on core 2. A number of the circuits described may be employed as sampling circuits 30-34, Fig. 3, in a five-digit-pulse decoder, the coded signals being received from a digit source 17 in serial form and read-out in parallel form on leads 40- 44. The presence or absence of each pulse in the serial code is then indicated by a positive or negative pulse, respectively, on the appropriate lead. The threshold property of the sampling circuits prevents response to spurious signals. As shown, the trigger pulse acting in a sampling circuit is applied over a delay circuit 35-39 from a common sine wave source 16, and the output is registered in a store 45-49. The five consecutive pulse positions of a coded digit occur during the positive half-cycle of the source 16, and the delay circuits are progressively graded so that each consecutive pulse position is coincident with the trigger pulse output from a corresponding delay circuit. In this arrangement the gates 24 are omitted from the sampling circuits and their positive or negative outputs, as the case may be, are registered in turn in the associated store. A readout device 50 is activated during negative halfcycle of source 16, and this causes all the stores to be read-out simultaneously whereby a pulse output is obtained in each lead 40-4. Specification 834,624 is referred to.
