Patent GB-1129995-A (GB)
Title: Improvements in and relating to electric insulating bushings
Inventor: COOK WILLIAM ARTHUR
IPC: H01B17/28
Filed: 1964-12-08
Abstract: 1,129,995. Insulators. MICANITE & INSULATORS CO. Ltd. 8 Dec., 1965 [8 Dec., 1964], No. 49909/64. Heading H2C. An electric insulating bushing is made by winding side-by-side on to a former or the like at least two sheets of flexible insulating material, e.g. paper, which initially overlap a distance W and are then cut by a reciprocating cutter in this overlapping region as they are fed forward together on to the former to produce complementary abutting serrated or tapered edges, as shown in the Figure. The pitch of the serrations is so related to the circumferential length of the layers that the abutting edges of adjacent layers are displaced laterally from one another, Fig. 4 (not shown). Layers of foil may be interleaved with the insulating sheeting to reduce electric stress. The insulation may be increased by impregnating the bushing material with, for example, an insulating oil or gas, or a plastics resin that may be cured during fabrication of the bushing by using heated rollers. Figs. 1 and 2 (not shown) illustrate the arrangement of the rollers and sheeting in the apparatus used in the method.

Abstract: 1325174 Selector switches BUNKER-RAMO CORP 2 Nov 1970 [31 Oct 1969] 52062/70 Heading H1N A selector switch comprises a base 14 carrying a plurality of fixed contacts 18 and a casing 16 slidable along the base and carrying a plurality of movable contacts 48 which can be lowered into engagement with a selected group of the fixed contacts, the casing 16 having teeth 60 which co-operate with recesses 42 so that the casing 16 can only be lowered when the contacts are aligned. The fixed contacts are in two rows and comprise strips of metal wrapped about projections 38 of the base. There are gaps (40) (Fig. 3, not shown) in the projections 38 between adjacent contacts 18 and aligned with these gaps are raised walls 42 in the space between the two rows. The movable contacts are mounted in a carrier 46 having downward projections 60 co-operating with the walls 42 to locate the casing 16 with respect to the base. To select new contacts a lever 52 is pivoted so that a cam 54 lifts the carrier 46, disengaging contacts and projections 60 from the base. The slide can then be moved along the base and finally the lever 52 pivoted so that the carrier 46 drops down on to the base under the action of springs (50) (Fig. 5, not shown) to re-engage new contacts. The fixed contacts are soldered at 72 directly to a printed circuit board which supports several such switches. The arrangement is employed (Fig. 1, not shown) in the programmed control of a knitting machine. A number of control signals recorded on a store member (8) are detected and fed to respective fixed contacts 18 of the switches while connections from the movable contacts 48 feed appropriate signals to the knitting machine.

In an automatic system for controlling the throughput of a continuous plastic extrusion process is determined by computation from the weight per unit area, speed and width of the product and the difference from a reference valve is used to control a plastic supplying device. As shown, plastic in a hopper 46 is fed by a screw 52 through a linear die 49 to produce a sheet 50 which is polished by rolls 54 and pulled from the die by rolls 56. The weight per unit area of the sheet is sensed by a radiation gauge 60 which, through a measuring and averaging circuit 62 and controller 66 controls motors 67, 68 driving rolls 54, 56 respectively. Signals representative of width, from a gauge 72, and sheet speed, from a tachogenerator 76, are processed in a throughput computer 70 together with the weight per unit area signal from circuit 62. The throughput signal controls an extruder screw motor 48 to maintain the feed from hopper 46 at the desired computed throughput valve.

Abstract: 1,192,711. Welding by pressure. FORD MOTOR CO. Ltd. 12 Nov., 1968 [29 Nov., 1967], No. 53458/68. Heading B3R. [Also in Division B8] In a device for positioning and holding an object e.g. the shell of a motor vehicle, in a predetermined position, horizontally pivotable clamping means are movable between a first position wherein the clamping means are in a clamping position and a plurality thereof define the perimeter of a holding zone, and a second position wherein the clamping means are outside the holding zone whereby the entry or exit of the object into or from the zone is permitted. A vehicle body shell comprised of panels 50, 51, 52 (Fig. 5) to be welded by a welding unit 115 which may be manual or automatic, is received at the welding station after assembly at a plurality of earlier stations each of which has skid-locators for accurately positioning the skids on which the panels are supported, and drive means for transferring the skids to a successive station. The arrival of the shell on a lift-drop table 105 of the welding station initiates the clamping procedure by causing the lift-drop table to move to a lower position. In so doing, a plurality of hydraulic or pneumatic cylinders 133-6 (Figs. 13, 14) are operated each to drive a cam follower 133-8 along a cam track (133-941) (Fig. 15, not shown) formed in part of a pivotable clamp support means 133-9, whereby the clamp support means, carrying the clamping means, pivot to a first position in which the clamping means are in the clamping position. The clamp support means, mounted on vertical supports 103, pivot in a horizontal plane. Four different clamping means (Figs. 17-19, not shown) are separately operable by piston-and-cylinder arrangements. Upon reverse pivotal movement of the clamp support means to the second position in which the clamping means lie outside the holding zone, the lift-drop table 105 is automatically raised and the shell, supported on the skids, is moved out of the station by driven rollers. A crosshead 133-7 at the end of the piston of the piston-and-cylinder arrangement 133-6, and mounting the cam follower 133-8, is guided between vertical guides 133-4, 133-5. The cam track is formed in a curved plate 133-94.
