Patent GB-1000841-A (GB)
Title: Improvements in or relating to the manufacture of strip-shaped articles from materials containing thermoplastic synthetic resins
IPC: B29C48/90
Filed: 1963-05-13
Abstract: 1,000,841. Forming thermoplastic sheet material; making flat films. SVENSKA CELLULOSA A.B. May 13, 1963 [May 14, 1962], No. 18930/63. Headings B5A and B5B. A continuous, substantially stress free, strip or film of material, containing a thermoplastic resin, is formed by extruding a heated tube 4 of the material around a cooled, double-walled mandrel 3, cutting the tube by a knife 5, then drawing the cut tube off the mandrel, and subsequently flattening and storing it on a suitable wind-up device. Contact between the tube and tho mandrel in zone I is prevented by compressed air introduced between the tube and the mandrel through inlet 3d. As the tube progresses along the mandrel to zones II and III it cools to an elastic state and shrinks into contact with the mandrel. The frictional forces caused by this contact are sufficient to prevent any stresses caused by the wind-up device from reaching the still plastic material in zone I, thus allowing the plastic material in said zone to cool to a substantially stress-free state. In an alternative embodiment the zone III comprises an expansible, non- cooled member, zone II having a smaller diameter than either zones I or II. Patterned products may be obtained by introducing different coloured granules into the working material which preferably comprises polyvinyl chloride together with a filler, e.g. chalk or kaolin.

Title: Improvements in electrolytic treatment of semiconductor bodies
IPC: C25D5/02
Filed: 1956-06-20
Abstract: 836,595. Electrolytic plating and etching of semi - conductors; semi - conductor devices. PHILCO CORPORATION. June 20, 1956 [July 13, 1955], No. 19081/56. Classes 37 and 41. A method of selectively electroplating a local surface area of a semi-conductive body comprises the steps of bathing said surface area with an electroplating electrolyte, forming within said body by means of a negative control voltage a localized region of potential negative with respect to said electrolyte and controllable in its extension towards said surface area in response to increases in said negative control voltage, and varying said voltage to bring about the selective electroplating of the said surface area. In a preferred form the body is first electrolytically etched and then plated by applying to a local surface area of the body an electrolyte which when positive with respect to the body produces plating and when negative thereto produces etching, raising the body to a positive potential and raising a localized region on said body opposite said area to a negative potential so as to create a depletion zone within said body, and varying said negative potential so that selective etching and plating are produced as desired due to the location of the depletion zone which determines which electrolytic action takes place. The negative control voltage may be adjusted so that etching of said surface area occurs until the depletion zone is exposed to the electrolyte whereupon etching is arrested and on increasing the negative control voltage plating occurs in the exposed depletion zone. The negative control voltage may be initially adjusted so that the depletion zone extends up to the said surface area so that when electrolyte is first applied to said area plating occurs. As shown, a wafer 10 of N-type germanium having an ohmic ring contact 11 and a surface barrier rectifying contact 22 which may be formed in the recess by the jet-etching and plating technique of Specification 824,484, is treated with a jet 13 of a plating electrolyte, e.g. an aqueous solution of indium trichloride brought to pH 1.25 with hydrochloric acid, while a voltage is applied between the wafer and the electrolyte through a positive electrode 19 and a negative control voltage is applied to the contact 22. By this means etching occurs until the boundary 26 of the depletion zone 25 is reached whereafter indium is deposited at 35 upon either increasing the negative voltage applied to the contact 22 and/or decreasing the electrolyte-wafer voltage. Instead of using a jet of electrolyte, the wafer may be immersed in an electrolytic bath, the recess, rectifying contact, and lead thereto being insulated as by wax. Reference is also made to the use of silicon as the semi-conductor, non-aqueous ionizing solvents for metal salts to provide the electrolyte, and to the production of surface barrier or alloy junction transistors. Specifications 810,946 and 826,916 also are referred to.

Title: Improvements in or relating to electric control apparatus for seam spot-welding
IPC: B23K11/24
Filed: 1937-07-13
Abstract: 498,884. Supply systems for resistance welding. SIEMENS-SOHUCKERTWERKE AKT.-GES. July 13, 1937, Nos. 19436 and 19437. Convention dates, July 13, 1936 and Feb. 5, 1937. [Class 38 (iv)] Thermionic control.-In seam spot welding control systems for A.C. employing two reversely-connected grid-controlled discharge devices, at least two periodic potentials independently adjustable in phase are applied to the grids to bring about independent control of the time of ignition and hence the current supply during the welding period and the alternate pause or non-welding period. The welding transformer 1 is supplied from the A.C. source 4 through two discharge devices 2, 3 in parallel with a resistance 15 and with the primary of transformer 14, the secondary of which is connected in the grid circuit of the two discharge devices. The grids receive from the source 5 positive control potentials preferably of rectangular shape which lead positive potential impulses from the source 4a, excited across resistances 9, 10 by transformers 7, 8 and given an approximately triangular form by a choke 11. The phase of the triangular impulses is adjusted by saturating D.C. winding of transformers 7, 8, the D.C. current being controlled by resistance 12. The rectangular control potential is effective during a number of half waves of the A.C. supply to control the welding period, its phase being adjustable to overcome the negative blocking potential applied by battery 6 and vary the instant of injection in each half cycle. The triangular impulses are ineffective when superimposed on the rectangular potentials during the welding period, but adjust the ignition timing during the non- welding period, when the rectangular potential is ineffective, to vary the current then supplied. In a modification, negative grid bias potential of different values may be employed and two independently adjustable impulses are used in addition to the rectangular potential. The leading impulse may be replaced by an A.C. potential of rectangular wave form.
