Abstract: 970, 566. Electric correspondence control systems. LANDIS MACHINE CO. Sept. 10, 1962 [Sept. 8, 1961], No. 34505/62. Heading G1N. [Also in Division G4] A system for repeatedly displacing a machine tool slide 84 through the same preset incremental displacement operates as follows. First the increment is preset by appropriately displacing the core of a differential transformer 10 thereby unbalancing a transformer system 10, 50. Balance of this system is then restored by driving the tool slide 84-and also the core of transformer 50-through the present incremental displacement. However displacement of the tool slide 84 also displaces the core of a transformer 70 thereby unbalancing a transformer system 70, 30. Balance of this system is then restored by driving the table on which the windings of the transformer 70 are mounted. The windings of transformer 50 are, however, mounted on the same table so that rebalancing the system 70, 30 unbalances the system 10, 50 by the amount by which it was initially unbalanced. The system is now back to its initial condition and a further displacement of the tool slide can now be made. When the tool slide reaches the end of its travel it can be returned to its starting position by associating- by appropriate switching-the transformer 10 with a transformer 130.

Abstract: 1,114,135. False twisting yarn &c. TEIJIN Ltd. 16 Aug., 1965 [27 Aug., 1964; 28 Jan., 1965., 3 Feb., 1965], No. 35071/65. Heading D1D.  In false-twisting filaments, a filament is run in frictional contact with the external surface of a head comprising a plurality of discs spaced apart along the axis of a rotating member, the filament being run obliquely with respect to the direction of rotation of the external surface, and fed and withdrawn from the head so that it is bent sharply around the end rims of the external surface. In a preferred form of head, the circumference of each disc is so shaped that the external surface of the head, considered as a whole, is barrel-shaped and the end-rim P, Fig. 9 of at least one of the ends discs projects axially beyond the end surface of the disc, so that a guide 3 may be positioned close to the head. To offset the tendency of the rim to be deformed by centrifugal force, a reinforcing inset 11 may be provided. By running the filament obliquely over the surface, the filament is subjected to a torsional force R sm #, Fig. 3, and a positive longitudinal feeding force, R cos #, in the direction of the filament axis the width of each disc may be less than its diameter. - There may be two discs comprising two spacer section of a barrel-shaped member, Fig. 7 not shown. Or there may be three spaced sections of such a member, the central section being greater in width than the end sections, Fig. 8 not shown. In Fig. 3, the discs are cylindrical and there are guides between them, so positioned as to cause the filament to change direction from one disc to another or to cause it to travel in a straight line. The guides may be so mounted as to be adjustable together. The head may be of one-piece construction, and comprise a cylindrical or barrelshaped inner portion having either alternating grooves and discs fitted with elastic rings or coated with elastic material, or rings of elastic material the end discs being made of harder material than the others.

Abstract: 1,001,150. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. Sept. 5, 1963, No. 35120/63. Heading H1K. A transistor comprises a triangular semiconductor die having connections to all electrodes on the same triangular face of the wafer. A plurality of transistors are produced from a wafer 11 of N-type silicon by a planar diffusion process comprising forming an oxide layer 12 on the surface of the wafer and etching apertures in this layer using a photoresist method P-type impurity is then diffused into the wafer through the apertures to form base-region 14 and the oxide layer is simultaneously reformed. The process is repeated to diffuse in N-type impurity to form emitter region 16. A further series of apertures are formed to expose contact areas of the regions and a layer of aluminium is evaporated on to the surface of the wafer and then etched away where it overlies the oxide layer. The wafer is then heated to alloy the aluminium to the silicon to form ohmic contacts 17, 18, 19. Large area contacts are then formed by evaporating a gold-chromium film on to the wafer grading from pure chromium next to the aluminium and silicon oxide surface to pure gold. This film is then etched to produce the contacts 20, 21, 22. The wafer is then scribed and broken along directions of easy cleavage to yield transistors in the form of equilateral triangles. The resulting transistor may be mounted in a thin film circuit by soldering it in upside down. The transistor may also be produced by forming the base and emitter regions in an epitaxial layer deposited on part of one face of the die whilst the collector electrode is formed in the remainder of the face. The large area contacts may also be of electroless nickel and the semi-conductor wafer may also be germanium, gallium-arsenide or other III-V compounds which also have a zinc-blend type tetragonal lattice. The triangular shape may be other than equilateral to produce desired parameters.
