Title: Improvements in or relating to thermoplastic films
Inventor: PARTON CHRISTOPHER GEORGE
IPC: B65D75/58
Filed: 1963-05-07
Abstract: 994,393. Films. IMPERIAL CHEMICAL INDUSTRIES Ltd. April 21, 1964 [May 7, 1963], No. 17988/63. Heading B5B. [Also in Division B8]  A thermoplastic film is weakened along one or more lines by heating the film along a line or lines to such a temperature that the film is partially softened or melted along the said line or lines without totally severing the film. Such heating may be effected by contacting the film for a short period with an element that is continuously heated, or by continuously contacting the film with an element that is heated for a short time, or by continuously passing the film over a continuously heated wire, or by contacting the film with the edge of a heated blade or roller knife. Preferably the heating element is a wire, spring loaded to accommodate any slack due to expansion and of 0.005-0.050 inch diameter, especially 0.010-0.030 inch. Weakening may be effected along one or more lines when the film is wrapped around an article, and a heated element with a continuous curved edge may be used to weaken the film around an area which may be later pressed out. Specified materials include polyolefins, e.g. polythene and polypropylene, vinyl polymers, e.g. polyvinyl chloride and polyvinyl acetate, polyvinylidene chloride, and vinylidene chloride/vinyl chloride copolymers and linear polyesters, especially polyethylene terephthalate. Preferred materials include biaxially oriented polypropylene and uniaxially oriented polypropylene. Film thicknesses of 25-500 gauge (100 gauges = 1 mil) are specified, especially polypropylene films of 50-100 gauge and polythene films of 110-220 gauge.

Patent GB-1442695-A (GB)
Title: Devices for laying layers of weft threads
IPC: D04B23/12
Filed: 1974-04-25
Abstract: 1442695 Cross-laying threads; knitting- machines WIRKMASCHINENBAU KARLMARX-STADT VEB 25 April 1974 [21 May 1973] 18126/74 Headings D1C and D1R An array of weft threads 5 is laid by laying means 2 between thread transport means 4, 4a which are aligned at an angle. The term threads includes slubbings, fleece webs and film webs. The laying means is characterised in that it allows the threads to be hooked simultaneously at each hooking of the weft array. The laid array is preferably transported to a stitch bonding or warp knitting means. In the embodiment of Fig. 1 laying means 2 comprises a beam pivoted at 3 and containing guide holes 13 for warp threads 5. The beam and the pivot are reciprocated by carriage 1. As the carriage moves from transport means 4 the tension in threads 5 holds the beam against stop 7 so that the beam is parallel to transport means 4a. The embodiment of Fig. 2 (not shown) is similar except that the thread laying beam, is normally held by springs (11) in an orientation bisecting the angle α between the thread transport means. As the carriage approaches a transport means 4, 4a a projection (12) of the laying beam strikes a stop (10, 10a), causing the laying beam to pivot against the action of the spring until it is aligned parallel with the transport means. In the embodiment of Fig. 3 the laying means comprises a plate 2 having thread guide slots 13'. Rails 14, 14a enclosing an angle α are mounted on the underside of the plate. Hence as the carriage travels towards the hooks of transport means 4a the tension in the threads 5 causes the point at which the orientation of each thread changes from vertical to horizontal to lie on a line 8 parallel to transport means 4a.

Title: Method and apparatus for effecting coil press-back in inductive devices
IPC: H02K15/06
Filed: 1967-04-21
Abstract: 1,137,698. Electromagnetic forming of coils. GENERAL ELECTRIC CO. 21 April, 1967 [28 July, 1966], No. 18414/67. Headings B3A and B3Q. A method of transferring an electrical winding carried by a core between initial and final positions, the winding comprising "n" coils. where " n " is even and not less than four, comprises the steps of rigidly supporting an electrically conductive means in electromagnetic coupling with one of the end turn portions of a first coil and the coil diametrically opposed thereto, shielding the conductive means from the remaining coils, electrically connecting at least the said opposed coils, establishing a transient magnetic field about the electrically conductive means thereby inducing current flow in the said opposed coils, thereby transferring one end turn portion of the said opposed coils to a desired position in the core by electromagnetic interaction between the conductive means and the end turn portions. Coils 20, 22, 24, 26 are loosely wound in the slots 12 of a laminated stator core 10 and are connected by interpole connections 258. A fixture 30 is placed in the bore 14 and series connected coils 34, 36 thereon are connected to the output terminals 44, 46 of an energy surge source 48. The coils 34, 36 are mounted in slots 70, 72 at right-angles to each other so that the end turns of the coil 34 are aligned with the end turns of the coils 22, 26 and the end turns of the coil 36 are aligned with those of the coils 20, 24. The side walls of the slots 58, 60, 62, 64 shield the remaining portions of the coils from the end turns of the other coil groups. When a surge of electrical energy is passed through the coils 34, 36, the magnetic interaction thereof with the end turns of the coils forces them outwardly to their final positions, Fig. 3. The current in the four coils induces eddy currents in the structure 30, which currents generate a magnetic field which interacts with the remainder of the coils to bend back the other end turns and compact the wires in the core slots. Permanent magnets for aiding the contouring of the end turns of the coils may be rigidly supported opposite these portions and are of the proper polarity to attract them. Construction of the fixture.-The cylindrical body of the fixture 30, which may alternatively be hollow, is made of a non-magnetic material such as copper or aluminium and is provided with insulation 32. The coils 34, 36 are wound on insulated formers 74, 75, which are secured in the slots 70, 72 and encapsulated therein with cured epoxy resin 84. Terminals 92, 94 are connected to the coils and held in place by the cured resin. In an alternative construction, the coils 34, 36 are replaced by permanent magnets (106), (108), in which case the winding itself is connected to the electrical surge source, Figs. 5, 6, 7 (not shown).

Filed: 1920-07-03
Abstract: 167,662. Woodburn, R. F. July 3, 1920. Welding.-Relates to an electric welding-machine in which the switch is operated by the pedal that brings the movable electrode on to the work, and consists in means by which further movement causes the opening of the switch while further pressure is brought on to the work. The fixed contact 1, Fig. 1, is spring-mounted on a bracket 11, which is connected by a pair of rods 12, Fig. 3, to the lever 16 which carries the movable electrode 17. The movable contact 3a is carried by an arm 4 pivoted to the bracket 11 at 5. The pedal-rod 10 is connected to the lever 16 by a spring 19. When the treadle is depressed the rod 10 rises and brings the electrode 17 down on to the work. The bracket 11 rises with the lever carrying with it the contact 1, while the arm 4 is swung up by a trigger mechanism 7, 8 such as described in Specification 135,238. When the electrode 17 is in contact with the work, the movement of the lever 16, bracket 11, and contact 1 is arrested. Continued movement of the pedal compresses the spring 19 and swings the arm 4 up to bring the parts 1, 3a into contact and complete the welding circuit. Further movement of the pedal releases the trigger mechanism 7, 8, and the arm 4 swings down to break the circuit while pressure is maintained in the work.

[Class 108 (ii)] In apparatus for protecting the tyres of motor vehicles comprising an extractor or deflector blade 12, or a plurality of such blades, set in operative relation to the tyre surface, each blade is mounted upon a carrier 2 and secured thereto by means 11 which are arranged automatically to release the blade from its mounting and so permit the blade to be discarded when the blade becomes worn to a predetermined degree. The blade 12 is supported by a frame comprising longitudinal arms 1 and transverse arms 2, 3, the whole being pivotally connected by bolts 4 to lugs 6 on a tubular bracket 7 secured to the vehicle frame by set bolts 14a. The member 3 is spring supported on a tongue 17 protruding from the bracket 7, and can be adjusted about the pivotal axis defined by the bolts 4 by means of a wing nut and bolt 21, 24. The blade 12 is secured to the member 2 by rivets 11 having countersunk heads which lie flush with the undersurface of the blade. These heads wear with the blade and when they are completely worn away the blade falls from the carrier and is flung away by the rotating tyre. In a modification, Fig. 5, the rivet 20 has a flat head 24 received in a counterbored hole 21 in the carrier 2, and a countersunk head 25 received by the blade 12. When the head 25 is sufficiently worn a compression spring 22 withdraws the rivet and allows the blade to be discarded. The fastening means are preferably of a soft material, such as copper or aluminium, and may instead of rivets comprise nuts and bolts, studs, staples or clips, or welded or brazed joints adapted to wear with the blade. The blade itself may be in several sections each independently secured to the member 2 and be made of a material having an elongation characteristic, under tensile test, of less than 20 per cent. The arms may be made of a similar material, to allow them to snap under excessive load. Means, such as electrical spring contacts, may be provided to give audible or visible warning when a blade has been discarded. Specification 578,851 is referred to.
