Patent GB-1602875-A (GB)
Title: Flexible electric cables with corrugated insulation and process for their manufacture
IPC: H01B7/04
Filed: 1978-04-20
Abstract: This is a flexible cable, insulated by means of a material which would possess, under the conditions of use of the cable, an insufficient flexibility. This cable includes one or more profiles, wound over the core (1), on which profiles the insulation is deposited thus forming corrugations. Flexibility is achieved by the movement of the corrugations and by the compression (squashing) of the profile. Application to cables for low temperatures or to cables for which the insulation would be relatively rigid at the use temperature. <IMAGE>

Title: Apparatus for holding films during developing, washing, drying and like operations
IPC: G03D13/14
Filed: 1928-05-29
Abstract: 291,337. Bourdereau, A. May 28, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Winding webs.-A rotary film holding device is adapted to support the film in spiral fashion with adjacent turns of the film spaced apart. The holder comprises a hub 5 with openwork cheeks 7, 8 having spoke-like arms provided with holes which, taken collectively, lie in a spiral path of constant pitch centred at the hub 5. In these holes rest pins 10 having a limited sliding movement parallel to the hub 5, and adapted, when displaced inwards, to form supports for the edges of the film. For winding or unwinding the film, the holder is detachably mounted in a framework upon slidable spring-loaded axles 13, 131 having keys 14 engaging the hub 5. The spool of film to be treated is mounted between a rotary fixed axle 1 and a non-rotary, spring-loaded, slidable axle 2 carrying a friction disc 3 which brakes the rotation of the spool. Mounted in bearings 20, 21 surrounding the axles 13, 13<1> are screwthreaded rods 18 prevented from rotation by keys 19 and engaging the internally threaded bores of gear wheels 17 driven by gear wheels on the axles 13, 13<1>, so that when these axles are rotated by turning the wheel 15 the rods 18 are longitudinally displaced. On the end of each rod are mounted members 25, 26 carrying inclined planes 27, 28 which are adapted to displace the pins 10. When winding film from the spool on to the holder, the wheel is turned to cause the inclined planes 27 to move radially away from the hub, so that the pins 10 are pushed in seriatim to provide supports for successive turns of film as they are wound on. To wind a finished film back from the holder to its spool, a pulley 29 normally loose on the shaft 13, is coupled to this shaft 13, is coupled to this shaft by a spring pin 30, so that the shaft 13 is coupled to the shaft 1 by a belt engaging the pulleys 29, 33. Rotation of the shaft 1 by a handle 32 then winds the film from the holder to the spool, and simultaneously produces displacement of the rods 18 so that the inclined planes 28 move towards the hub 5 and push the pins 10 outwards seriatim, as these are relieved of film, leaving a free path for the film between the holder and the spool.

Title: Improvements relating to electrical capacitors and methods of manufacture thereof
IPC: H01G13/00
Filed: 1963-04-24
Abstract: 966,287. Laminates and laminating. SIEMENS & HALSKE A.G. April 24, 1963 [April 25, 1962], No. 16099/63. Heading B5N. [Also in Division H1] A composite dielectric and metallic strip for use in the manufacture of a capacitor is composed of a basic synthetic or paper dielectric strip 1 having a layer of varnish or lacquer 2 applied thereto and a metallic layer 3 applied to this layer by vapour deposition. In the course of manufacture of the strip the varnish or lacquer layer is shifted either lengthwise and/or transversely relatively to the basic strip after application of the metal layer. This ensures that pores which initially run through the whole thickness of the strip have their opposite ends displaced relatively to one another so that the breakdown resistance of the capacitor dielectric is increased. Several composite strips may be combined together to form a wound capacitor (Fig. 5). An arrangement for carrying out the displacement of the two dielectric strips may consist of an arrangement of rollers 10 (Fig. 8) which control the varnish or lacquer layer, while the basic layer hangs in a free loop, which is displaced sideways by either a pin 14 or a tilted roller 12, so that when the two layers are recombined they have been displaced both lengthwise and transversely to one another. An alternative arrangement for lengthwise displacement only uses a wedge-shaped blade to separate and provide different tracks for the two layers which are then recombined (Fig. 6, not shown). The re-combining of the layers may be effected by relying on electrostatic attraction or by using, additionally, a heated pressure roller. The varnish or lacquer layer may consist of Polystyrene, cellulose acetate, nitro-cellulose, polycarbonate or ethylcellulose.
