Title: Improvements in or relating to laminated stators for electric motors
IPC: H02K1/16
Filed: 1956-09-06
Abstract: 811,183. Making stator cores; welding by pressure; coiling. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Sept. 6, 1956 [Sept. 12, 1955], No. 27321/56. Classes 83 (2) and 83 (4). [Also in Group XXXV] In a stator coil for an electric motor comprising toothed laminations held together in a compressed unit by a plurality of welds extending transversely across the peripheries of the laminations each lamination is formed with a tapered portion the thickness of which decreases from the roots of the teeth towards the outer periphery of the lamination and each weld is effected by pressure welding with a material which softens during the welding, operation and enters the spaces between the tapered portions of the laminations. A strip STR, Fig. 1, of oriented silicon steel is stamped with slots 21 and slits 22 to form two toothed strips ST. A strip ST is passed between adjustable tapered rolls to taper the metal from the roots of the teeth all or part of the way to the edge of the strip to cause the strip to form itself into an edge wound helix. As shown in Fig. 2 a narrow rib 37 may be formed on the edge of the strip. The helix is compressed by four spaced clamps 45, Fig. 8, while arranged on a mandrel having keys to enter the spaces between the teeth, the mandrel' being then removed. A steel rod 61 is held axially along the helix by an electrode E1, the other electrode E2 being in contact with the laminations and current is passed to fuse the rod into the periphery of the helix. When laminations as in Fig. 2 are used the rib 37 upsets to allow the penetration of the weld metal. Eight such welds may be made. In a modification a keyed mandrel is left within the helix while the helix is compressed by pneumatic or hydraulic means and each electrode welds a rod to the helix.

Title: Tubular thermoplastic biaxially oriented film manufacture
Inventor: RIGGS AUBREY FRANK
IPC: B29C55/28
Filed: 1961-07-28
Abstract: 965,003. Tubular films. IMPERIAL CHEMICAL INDUSTRIES Ltd. July 4, 1962 [July 28, 1961], No. 27439/61. Heading B5B. In a continuous vertical tubular biaxial orientation process of thermoplastic film manufacture in which the extruded tube is fed downwards, and heated by infra-red heaters to a temperature below the softening point suitable for inflation, the infra-red heaters are at least partially enclosed by a housing surrounding them and the tubular film, through which housing a controlled circumferential vertical upward air current is maintained. The housing may surround the heaters and the whole zone of stretching of the film or may extend only to the level of the lowest heater. The air current may be cold or heated and may be " force-fed " or induced by convection. In one embodiment, a tube of thermoplastic 1, e.g. polyethylene terephth late, polyethylene, polypropylene or poly-4-methyl-pentene-1 is passed downwardly between nip rolls 2 wherein is a probe for admission of inflating gas (see Specification 787,479), through infra-red heaters 4 and 5 at 800‹ C., and ceramic heater 16, stretched, passed through baffle 6, and then collapsed by guide rolls 7 and taken off by nip rolls 8. Housing 9, surrounding heaters and tube, is provided with circumferential openings 10 and 11 for passage of air therethrough. Air is admitted through baffle 6 which consists of two circumferentially movable rings 12 and 13 having apertures, the size of which may be varied by relative movement of the rings, thus controlling ingress of air. Alternatively, the air current may be controlled by adjustment of apertures 10 and 11 before start-up. Cylindrical guides 15 within the housing reduce turbulence. The housing may be sealed against the tube at the lower end by a ring 14 of polyethylene terephthalate staple fibre projecting inwardly against, and deflected downwardly by the stretched tube. Alternatively the seal may comprise a sheet having a hole for the tube, as disclosed in Specification 908,169. In another embodiment the part of housing 9 below heater 5 may be omitted, in which case the lower air inlet is the annular space between heater 5 and the tubular film. In a further embodiment in which the lower part of the housing, and rings 12 and 13 are omitted, the current of air may be varied locally around the circumference of the tube by providing a ring similar to ring 13, but having a substantially continuous annular opening therethrough, and a series of spaced members movable radially over the horizontal surface of the ring so that the effective width of the annular opening may be locally varied. The process of the invention reduces " wander " of the film during extrusion by reducing adventitious draughts. The apparatus may be used in conjunction with the process disclosed in Specification 954,254.
