Title: Improvements in and relating to electrical transformers and methods of forming the coils thereof
IPC: H01F27/28
Filed: 1921-02-03
Abstract: 179,609. Imray, O., (Pittsburgh Transformer Co.). Feb. 3, 1921. Transformers.-A transformer coil is formed by winding successive layers under tension along a curve of continuously varying curvature. For this purpose, one end of the conductor is secured to a rotatable mandrel 7, Fig. 3, of oval or elliptical cross-section, the free end of the conductor being held in a tensioning-device 9. A long narrow coil, with the conductors under continuous tension and mutually binding each other in the various layers, is thereby produced. In applying the invention to a shell-type transformer, Figs. 5 and 6, the second winding 13 is placed between two portions 11, 15 of the primary winding, the windings being separated from each other and from the centre leg 21 of the coil by insulating- barriers 10, 12 and 14. Successive layers in each of the windings are separated by spacing-strips 17, in order to leave vertical ducts 18 for the circulation of oil or other cooling-fluid. The strips 17 may increase in thickness towards the overlapping ends c of the coil in order to provide increased ventilating spaces at the portions where the oil circulates most freely. The oil conductors are preferably flat, and a number of them may be bound together to form a stranded conductor. In the arrangement shown in Fig. 7, each conductor 14<1> comprises a pair of square wires 41 bound together by a string 42 or by fabric 43. In a modification, Fig. 8, each conductor is in the form cf a ribbon composed of eight strands s of square wire bound together in a covering 43<1> of fabric. The string or fabric, as well as the insulating-barriers and spacing- strips, are made of absorbent material, and the completed coil, after drying, is treated with liquid varnish in a high vacuum. The varnish used is preferably of the type hardening by evaporation of a diluent and by oxidation, such as a mixture of linseed or chinawood oil with a gum such as resin or copal diluted with gasolene or naphtha.

Abstract: 1,070,248. Ribbon cables; circuit assemblies. STANDARD TELEPHONES & CABLES Ltd. Jan. 31, 1966, No. 4137/66. Headings H1A and H1B. [Also in Division H2] An interconnecting wiring assembly is formed from a network of bare wires by bonding wires together at selected crossing points and then treating the wires so as to produce an insulating surface layer which insulates the wires from each other at the other crossing points. The assembly may be formed from a woven mat of wires of aluminium, tantalum or titanium welded together at selected points 4 and then anodized to produce the insulating layers and, if desired, treated to seal the anodized surface. Connections 8 may be made to all unused wires from the outer horizontal wires, and wires 6 may be cut where required. Apertures 7 may be formed in which semi-conductor integrated circuits 1, thin film circuits or the like may be located, the connections being made by ultrasonic welding or after removing the anodized film, and the whole assembly constituting, e.g. a shift register. The circuit elements may be connected into the mat before anodization and then masked during the anodizing treatment, and the assembly may be corrugated and potted in an insulating resin. The circuit elements may be arranged to one side of, rather than between, the longitudinal conductors.

Abstract: 904,139. Sliding clasp fastenings. OPTIHOLDING A.G. Feb. 5, 1959 [Feb. 6, 1958], No. 4152/59. Class 44. Apparatus for use with single or double-stitch sewing machines for making sliding clasp fasteners by sewing one or two threads of synthetic plastics material into one or two stringer tapes respectively, comprises a supplying device for the thread, a guide path for the thread, a separating knife for cutting the thread into predetermined lengths and being actuated under the control of a length-measuring device after passage from the supplying device, the operation of the supplying device and the length-measuring device being stopped when the knife is operated and an electrical control device between the knife and the sewing machine, which starts the operation of the supplying device and the length-measuring device when reached by an end of the cut-off length of the thread. As shown, pre-formed toothed thread 2 of plastics material is fed from a drum 4 along a guide path 1 to a sewing machine A where the thread is stitched to a stringer tape 17. Preferably, two interlocked threads are fed from the drum 4 for sewing to respective stringer tapes simultaneously. The length-measuring device comprises a roller 6 driven by the moving thread 2 and driving on an endless strip 8 which controls switch contacts 12, 13 of a switching relay 14 controlling the drum 4. When the latter is stopped, a knife 5 operates and the separated lengths of thread 2 continue to move towards the sewing machine A until the forward end abuts a contact 16 which closes a circuit for re-starting the drum 4 and hence the roller 6. The position of the contact 16 is adjustable to vary the distance between the separated lengths of thread. The length-measuring device may comprise an electronic control with a resistance/capacity time base. The fastener elements may be formed as a continuous oval section coil, Fig. 2 (not shown), attached to a guide cord; a flattened coil, Fig. 3 (not shown), or a series of teeth joined by coupling parts and shaped by stretching.

Title: Optical fibre connector
IPC: G02B6/36
Filed: 1976-02-03
Abstract: In the method, cylinders (1a) are arranged with their circumferential surfaces one against another. The fibres (3) to be connected are inserted individually from one direction in each case into the interspaces formed between the cylinders, and fastened therein, e.g. by encapsulation. Thereafter, the end faces of the cylinders and of the fibres can be ground flat, so that it is possible for two identical endpieces, e.g. in a guide piece (6), to be connected to one another in a manner precisely aligned with respect to one another. The method permits cost-effective production of precisely matching endpieces. <IMAGE>

[Class 7 (ii)] [Also in Groups XXIV and XXIX] In a power plant for driving a single shaft from a number of separate engines, the drive from each engine includes a one-way. clutch for normal driving and a friction or dog clutch put into operation automatically when the speed of the driven shaft is below a pre-determined minimum, by a governor on the shaft acting through a fluid pressure servomotor. The shaft 14, e.g. the propeller shaft of an aeroplane, is provided with a gear 41 with which meshes a number of pinions 12 each driven from a separate engine. The crank shaft 1 of each'engine is connected by a coupling 3 to a shaft 2 to which is secured a ratchet wheel 5 between which and a casing 6 to which the pinion 12 is secured is arranged a number of clutch rollers 7. The casing 6 is formed with an internally coned portion 13 with which co-operates a clutch member 16 slidably mounted on an extension of' the ratchet wheel 5 and engaged by the piston rod 19 of a piston 20. The clutch 16, 13 is normally held open by a spring 18. A governor 35 on the shaft 14 is operatively connected to a piston valve 26 controlling the supply of pressure fluid, which may be the oil of the forced lubrication system of the engine, to the cylinder 21 of the piston 20. At low speeds, the valve 26 is in the position shown and the fluid passes from supply line 29 to the cylinder 21 holding the clutch 13,16 closed. At high speed of the shaft 14, the valve 26 is operated to connect the cylinder 21 with the exhaust 28 and the clutch 13, 16 is opened by the spring 18.
