Title: High frequency electric welding
IPC: B23K13/04
Filed: 1959-04-23
Abstract: 891,628. Welding by pressure. ARMCO INTERNATIONAL CORPORATION. April 23, 1959, No. 13922/59. Class 83 (4). In making a welded seam free from flash on one side by electric resistance or induction welding using current of 10-1000 kc. per sec., the edges of metal sheet or strip to be welded are brought into contact only on the said one side to leave a V-shaped gap between the edges which are heated to welding temperature by high-frequency current and are angularly displaced to force them into contact. In an embodiment a flat strip 13, Fig. 1, is formed into an open tube and the edges 10, 11 are scarfed to form a V-gap 18, Fig. 2, where they contact, having an included angle of 5-45 degrees. The tube adjacent the edges is engaged by a pair of sliding contacts 15, 16, which may be brushes, shoes or rollers, which supply high-frequency current, e.g. 450 kc. per sec. to flow along the edges around the weld point 12. Rollers 14, 14 force the edges to close the V-gap to result in a substantially smooth inner surface and a shallow outer flash. In a modification, an induction heater 25, Fig. 4, heats the edges. Instead of scarfing the edges they may be perpendicular when the tube is formed as in Fig. 5, to form a V-gap but in this case the welded tube may not be circular. It may be sized subsequently. Flat sheets or helically-wound tubes may be welded and the material may be ferrous, non-ferrous or an alloy. A plug of high magnetic permeability may be used to localize the magnetic field.

IPC: A43D23/06
Filed: 1951-06-18
Abstract: 686,649. Trimming shoe upper linings on last. BRITISH UNITED SHOE MACHINERY CO., Ltd. June 18, 1951 [June 20, 1950], No. 14339/51. Class 17 (i). Surplus lining material at the toe end of a shoe upper on a last is trimmed away in a machine comprising a movable carriage 18, Figs. 1, 2, 3, 4, on which a circular knife 118 is mounted with its cutting edge arranged in shearing relation to the lower faces of wipers 44, 46 suitably shaped to accommodate the toe end of a shoe and having ears 50, 52 which engage the shoe bottom. Figs. 2, 3 show, respectively, the initial and a subsequent stage of the trimming operation. The wipers 45, 46 constitute a shear member and are movable widthwise of a U-shaped shearing bed member 16 towards one another in recesses in its lower face and against which the toe portion of the upper is spread, on movement of the knife towards the wipers. Adjustable cam followers 58, 60 in cam slots 54, 56 in the carriage 18 control the amount of widthwise closing movement of the wipers. The member 16 is bolted to the main frame 10 of the machine which is supported on a stand 12, and the carriage 18 is movable backward and forwards on rollers 20 on the frame from a shaft 148 driven from a motor 142 through a single revolution clutch controlled by a treadle 218, and guide rods 168, 170 through arms 152 and rods 156, 158. The knife 118 is rotated by a pinion 134 and rack 138, when the carriage 18 moves, to effect a draw cut on the work as well as a shearing action. A toe abutment 4 is adjustable relatively to the shearing plane of the shearing member 16, being supported on a block 26 in inclined bore of which the abutment is received. A heel rest 30 is provided and also a slightly resilient tongue-like toe support 42 hinged on a pin 40 to front of frame 10 and extending over carriage 18. As a fulcrum roll 140 pushes upwards on support 42 with the advancing movement of knife 118, the last is caused yieldingly to tension the clamped lining and upper downwardly over the toe contours. This tension is maintained by the operator during trimming by pressing against the back of the last. Lining spreading members 82, 84 are pivoted on the carriage 18 so as to be swung apart about their heelward ends and are moved apart at their toeward ends by rolls 102 in cam slots 104, 106 in levers 108, 110 pivoted on machine frame. Rolls 114 on the levers 108, 110 ride in V-shaped cam tracks 116 in part of the carriage 18 to spread the lining outwards against the member 16 in readiness for the knife to cut into it. A member 98 lies centrally between the spreading members 82, 84 to wipe outwardly the centre portion of the lining. The spreading members are urged by springs 94 toward the shoe bottom.

Abstract: 746,998. Abrasive tools. BOART PRODUCTS, SOUTH AFRICA, Ltd. May 17, 1954 [May 26, 1953], No. 14401/54. Class 60 [Also in Group XV] A single layer abrasive tool is formed by imprinting a pattern of adhesive elements on to a backing surface, causing abrasive particles to adhere to the adhesive elements and forming a metallic matrix on the backing surface to support and hold the abrasive particles. Adhesive elements 8, Figs. 1 and 3, of a desired pattern are printed on the surface of a backing plate 7 by hand, by a rubber stamp or by a knurled roll. A heat-curable adhesive is used. Abrasive particles 10, e.g. diamond boart, are then spread over the surface and those particles not adhering to the adhesive elements are brushed or blown off. The surface is then electroplated to form a layer 12 of copper, nickel or iron or a combination of these. The assembly is heated to cure the adhesive either before or after the electroplating. In a modification, Figs. 6 and 8, adhesive elements 8 are imprinted on a blank 3, which may be flat or contoured. Abrasive particles 10, which may be mixed with salt are scattered over the surface and the non-adhering particles removed e.g. by brushing. A metal layer 13, e.g. of copper, having a thickness equal to the desired protrusion of the particles 10 from the finished tool is electrolytically deposited, followed by deposition of a layer 14 of nickel or iron to cover the particles 10. The electrodeposited metal is all removed from the blank 3 and soldered or otherwise permanently fastened to a backing plate 2. The layer 13 is etched away to expose the particles 10. The blank 3 may have a film of oil, wax or graphite to facilitate separation. The backing plate 2 may be affixed to the layer 14 prior to removing the electrodeposited material from the blank 3.

Title: Improvements in and relating to the manufacture of articles consisting wholly or partly of perforated rubber sheet
Filed: 1939-05-15
Abstract: 528,781. Compound sheets of rubber and textile fabrics. INTERNATIONAL LATEX PROCESSES, Ltd. May 15, 1939, No. 14438. Convention date, May 21, 1938. [Class 140] [Also in Group V] In making perforated rubber sheets which may be backed with knitted or other textile fabric, a layer of an aqueous dispersion of rubber is perforated by spaced pins while in a plastic state and before it has become elastic. A latex mix from a tank 10 is discharged on to an endless travelling belt 11 which carries the layer beneath a doctor 16, a heater 19, a pin-carrying roll 21 moved at the same speed on the belt, and heaters 30, 31 and a drying fan 32 which renders the layer elastic. The layer is stripped from the belt and wound upon a roller 28 with a lining cloth 29 between the convolutions. A chemical coagulant may be applied to the layer after it leaves the roller 21. The pins may be pointed, blunt or tipped with soft resilient rubber. The deposition surface may be of hard rubber or glass or of yielding material such as textile fabric or of soft rubber, the surface of which may be halogenated to reduce adhesion of the layer to it. A textile fabric T from a roll 33 may be drawn round rollers 34, 35 and pressed on to the layer. The supply of latex mix from the tank 10 may be omitted and the fabric T be coated by latex mix from a tank 40, and the latex layer be perforated by the roller 21 which is moved on an arm 44. Alternatively, a layer of fabric T' from a roll 37 is fed on to the band 11 before it passes beneath the tank 10, the coated fabric being passed on to a roll 39. The belt 11 in this case may be omitted. The belt 11 may be made of stretchable material and be stretched between the rollers 12, 13. On contraction, the perforations are brought closer together and if a textile fabric is attached, it becomes condensed and depressed into the perforations. The fabric may be condensed as described in Specification 448,669 before applying it to the rubber layer. In place of the roller 21, an endless band of card clothing may be used and the rubber layer may be carried by the pins until it has become elastic. The rubber sheet is vulcanized before or after it leaves the travelling belts. Reference has been directed by the Comptroller to Specification 486,215.
