Title: Apparatus for cutting and joining tapes
IPC: H01B13/26
Filed: 1957-05-21
Abstract: 812,849. Making electric conductors; shearing; welding. WESTERN ELECTRIC CO. Inc. May 21, 1957 [May 22, 1956], No. 16089/57. Classes 83 (2) and 83 (4). In a machine for cutting and joining a pair of tapes in overlapping spaced relationship, a movable cutter initially positioned between the tapes severs the lower tape immediately before the tapes are joined and is subsequently moved around an edge of the joined tapes to its initial position. The machine provides a continuous supply of aluminium strip to a forming machine which forms the strip, after corrugating if desired, to sheath an electric cable. The strip 12 being used is supplied from a coil 11 on an arbor 36 through adjustable guides 21, 27, 30, 31 over the work-table 17, a tensioning device 16 and a roller 67 in raised position to the forming rolls. Strip 32 from a second coil 33 on an arbor 37 is passed manually over a rest 42 and between the guides 21, 27, 30, 31 to a manually actuated set of rollers 60 which hold the end of the strip 32. As the coil 11 nears exhaustion, a pivoted arm 61 actuates a switch 62 whereupon a ram 65 lowers the roller 67, and further rams withdraw the rest 42 and lower clamps 47, 52 which clamp the superimposed strips 12, 32 on to the work-table 17. The roller 67 is gradually raised and allows for continuous operation of the forming machine. At the welding and cutting station the strips 12, 32, Fig. 4, are spaced by a fixed blade 80 and a moving blade 77. The welding and cutting head 76 is lowered by a lever 72 actuated by a fluid pressure cylinder. The head 76 carries a movable blade and welding die 81, which co-operates with the fixed blade 80 to shear the upper strip 32, and an abutment 86 which through the strip 32 engages a movable blade 87 co-operating with a fixed blade and welding die 82 to shear the lower strip 12. The welding dies have serrated tool faces which join the strips 12, 32 by cold pressure welding. The cutting and welding is along lines oblique to the axis of the strip. The moving blade 87 is vertically slidable on rods 92, 95 mounted on a carriage 100 traversable horizontally on fixed rods 102, 105. During the cutting action, a roller 140 on the blade 87 displaces a spring- loaded latch 130, and is engaged in a recess 132 in the latch 130 with the blade 87 positioned below the welded strip while the welding and cutting head 76 is raised. Subsequently a fluidpressure ram 121 reciprocates the carriage 100 and the roller 140 moves below a fixed rail 125 until the blade 87, having been retracted clear of the strip, is lifted by a spring 101 and the carriage 100 and blade 87 are returned to their normal position. The rest 42 is extended and the clamps 47, 52 raised. The arbor 36 is removed, the coil 33 is moved down into the lower position and a new coil inserted in its place. The operations are effected by swinging the locating arms 40, 41. below the supports 35.

Abstract: 400,330. Turning-gear. CARTER, J., Amara, Farnborough Road, Farnborough, Hampshire. June 10, 1932, No. 16361. [Class 7 (v).] In a hydraulic engine starter, a gear pump 8 draws fluid from a reservoir 29 formed in the starter casing and forces the fluid on to rotor vanes 13 and on to a ram 14 which effects the engagement of clutch dogs 15 with the engine shaft, so that the rotary motion of the vanes 13 is transmitted to the engine shaft. The casing 1 is divided by a partition 2 into an upper chamber for the rotor 13 and a lower or reservoir chamber 29, the partition being provided with inlet and exhaust ports 7, 7a for the driving fluid. Fluid from the pump 8 is forced through a pipe 31, three-way tap 26, and pipes 32, 33 leading respectively to the inlet port 7 and to the space behind a cup washer 17 on the end of the ram 14. The gear pump 8 is driven through spur gearing 22 from a handle 24 or an electric motor. The pump 8 may also be driven by an air-driven turbine 10 supplied with compressed air through a union 9, the compressed air also being used to effect the axial movement of the ram 14 and clutch 15. For this purpose, the air from the turbine 10 passes through a ball valve 25 and acts on the cup washer 17 ; and fluid from the pump 8 is byepassed by the three-way tap 26 instead of acting on the ram.

Abstract: A process of producing a smooth lustrous surface on articles, for example, electric torch cases, of aluminium or aluminium-rich alloys, consists in immersing the article at an elevated temperature in an electrolyte containing phosphoric acid, sulphuric acid, an organic substance within the group consisting of aliphatic-polyhydric alcohols and ether alcohols soluble in phosphoric acid, and water, for a short period without the application of a voltage, whereby etching is effected, and then subjecting the immersed article to direct current voltage, the article being made anode in the bath. The alcohol may be an alkylene glycol or ether thereof having a boiling point above 120 DEG  C.  After the polishing process the article may be immersed in a solution of caustic soda, in a mixture of chromic anc phosphoric acids or chromic and sulphuric acids, or in solutions of the salts of these acids, to remove surface film, the article thereafter being anodized in a bath containing chromic acid to obtain an opaque film or sulphuric acid to obtain a transparent film.
