Abstract: 895,326. Semi-conductor rectifiers. GENERAL ELECTRIC CO. Ltd. June 10, 1959 [June 18, 1958], No. 19478/58. Class 37. In a semi-conductor device of the kind in which one portion of a semi - conductor body is in good electrical and thermal contact with a metallic part of an envelope, which encloses the said body and is adapted to be maintained in good thermal contact with a metallic member outside the envelope, the lead for a second portion of the said body includes a relatively massive part disposed inside the envelope and in good thermal contact with said second portion. As shown, a rectifier for use with low-frequency A.C. comprises a wafer 1 of P-type silicon, of which one surface is doped with boron to produce a low resistivity P-type region, and the opposite surface is doped with phosphorus to produce a region of N-type conductivity, each surface being subsequently plated with nickel and then vapour-coated with gold. The diode thus formed is mounted between two cylindrical copper blocks 3, 13, the contact surfaces of which are coated with gold, a lead disc being interposed between the diode and each copper block and soldering being effected by heating the assembly at 400‹ C. in a nitrogen atmosphere, a wire 15 having been previously brazed to the base of a central conical recess 18 in the block 13. The exposed portions of the diode are then coated with silicone resin which is heat cured, after which a copper cap 4, into which a copper tube 12 to accommodate wire 15 is sealed through a glass bead 11, is placed over the diode and the block 13, and flanges 5, 6, on block 3 and cap 4, respectively, are sealed by cold welding in a nitrogen atmosphere. A threaded stub 7 at the end of block 3 remote from the diode facilitates its clamping to a metallic cooling- member 8. Specification 817,636 is referred to.

Title: Improvements relating to ignition magnetos for internal combustion engines
IPC: H02K21/28
Filed: 1932-07-12
Abstract: 404,318. Magnetos. LUCAS, Ltd., J., and LAIRD, J. A., Great King Street, Birming- ham. July 12, 1932, No. 19665. [Class 35.] Inductor machines.-An ignition magneto adapted to run at engine speed and to give one spark per revolution has an unsymmetrical rotor or stator whereby flux changes through the secondary winding sufficiently rapid to produce a spark independently of the interrupter are avoided. As shown applied to a magneto of the rotating armature type, Fig. 1, the armature poles b overhang one side of the core more than the other and one magnet pole-piece c subtends a greater angle than the other. In another form, Fig. 6, the parallel longitudinal edges of the armature poles b and the edges of the magnet pole-pieces c are inclined to the axis of rotation. With both forms of construction, a slow flux change takes plate at the positions shown and after rotation through 180‹, the armature and magnet pole edges coincide so that a normal spark is obtained. The invention is applicable to magnetos of the rotary magnet and inductor types. Specifications 26323/12 and 179,147, [both in Class 35, Dynamo-electric generators &c.], are referred to.

Title: Improvements in or relating to imparting latent or potential crimp to synthetic filaments
Inventor: EDINGTON ROBERT ALEXANDER
IPC: D02G1/00
Filed: 1962-05-24
Abstract: A latent or potential crimp is imparted to continuous synthetic linear polymer filaments by heating the filaments non-uniformly while causing them to travel rapidly across a narrow surface heated to a temperature above the melting temperature of the filaments in such a way that the filaments are heated on one side only continuously along their length.  The heated narrow surface is provided on a heated member having an appreciable thermal capacity whereby fluctuations in the temperature of the narrow surface are minimised.  The process resembles that described the applicants Specification 808,213, but the narrow surface disclosed in that Specification is an electrically heated wire, pin or bar, the heating being, for example, effected by the resistance of the wire and has been found rather difficult to control owing to the heated wire &c. not having sufficient thermal capacity.  The potentially crimped filaments may be heated and relaxed (whereby the latent crimp is brought out) by subjecting them to a heat treatment while they are under a tension which permits either free or controlled shrinkage.  The temperature of the heat treatment may be above the second order transition temperature of the filaments and below their melting temperature. The member providing the narrow surface may be made of a heat-conducting, abrasion-resistant material such as tungsten, molybdenum tungsten carbide or ceramic material.  The member may be formed of a softer metal having an outer layer as above.  The member may be in thermal contact with a heated body by which it is indirectly heated.  The heated body may contain an electric heating element, or may be heated by heat exchange with a heated fluid or may be heated indirectly by radiated heat.  The bundle of filaments to be treated is preferably passed over a convex surface (termining near to, but effectively heat insulated from the heated narrow surface) whereby the bundle of filaments is spread out laterally to form a ribbon before passing over the heated narrow surface.  The latter may initially be provided with grooves corresponding with the mean filament path, or such grooves may be worn in the surface after a period of operation.  The process of the invention may be preceded by a drawing process.  The filaments may consist of polyethylene terephthalate or of nylon 66.
