Title: Production of metal articles.
IPC: B21C23/14
Filed: 1969-02-17
Abstract: 1,213,432. Extruding. KABELUND METALLWERKE GUTEHOFFNUNGS - HUTTE A.G. 12 Feb., 1969 [20 March, 1968], No. 7604/69. Heading B3P. A backward extrusion process is performed by a press tool 3 in a die 2 on a metal blank whose backward flow is controlled by a die part which moves with the metal flow. The die part may be a freely mounted pin 4 when the blank is shaped into a pipe end with an external flange or a sleeve 10 when the flange is internal. The part may be driven at a speed at least equal to the rate of flow or it may be moved by the metal flow. The initial blank is disc-shaped and punched by the pin 4 or the die 9. The punched-out disc is used in a similar process for smaller pipe ends. The metal may be a copper alloy with zinc and aluminium.

Title: Recovery of zinc.
IPC: C22B19/20
Filed: 1976-02-13
Abstract: A pollution-free process for the recovery of high purity zinc from zinc containing material including sulfide ores which provides for maximum conservation and re-use of reagents, the process consisting of chlorinating the materials either with ferric chloride or chlorine gas followed by selective removal of metals other than zinc by standard procedures, such as, lead chloride crystallization, cementation, etc. to produce a solution containing essentially only zinc chloride and ferrous chloride. To enhance the purity of the zinc end product zinc chloride is separated from the ferrous chloride solution with a zinc selective extraction agent from which the zinc chloride is stripped with sodium chloride solution in a sodium chloride stripping circuit followed by precipitation of zinc as the carbonate. The sodium chloride formed in precipitating zinc carbonate with sodium carbonate goes to an electrolytic cell to produce chlorine and sodium hydroxide by electrolysis which latter is carbonated to sodium carbonate for circulation to the zinc carbonate precipitation. The sodium chloride stripping circuit includes the electrolytic cell where excess chlorine is removed from the stripping solution. The ferrous chloride raffinate from the zinc chloride extraction step is sent to a chlorination and hydrolysis step where ferric chloride leaching agent is regenerated and iron removed. Chloride from the electrolysis step is used for the chlorination step. The process results in very little loss of reagents from the system.

Abstract: 1,213,269. Film fibrillation. CHEVRON RESEARCH CO. 1 July, 1969 [3 July, 1968], No. 33264/69. Heading B4B and B5B. A cutting device useful in fibrillating uniaxially oriented polymeric film 13 comprises a roller 16, on the surface of which are formed longitudinal rows of elevated substantially equidistant cutting elements 21, the lateral offset between successive elements in consecutive rows being 0À5-50 mils, and a roller 17 having circumferential longitudinal grooves 22. The rollers are positioned with their circumferential surfaces parallel such that elements 21 penetrate but do not touch grooves 22.

Title: Stepper motor control
IPC: H02P8/32
Filed: 1982-04-28
Abstract: A method and apparatus for controlling a stepper motor and a disk drive is described for minimization of stepper motor oscillations for a single step, minimizing the time taken for the stepper motor to move between tracks for multi-track seeks, and reduction of angular hysteresis due to the mechanical and magnetic properties of the stepper motor construction. This control is achieved using a microprocessor-based circuit adapted to drive the stepper motor in accordance with predetermined programs. Oscillations of the stepper motor are damped by controlling, using one program, the current applied to the stepper motor during the last step of its motion by switching this current on and off within small predetermined time intervals. The time taken to move between tracks is controlled by another program in which the non-linear torque speed characteristics of a particular stepper motor are matched by a non-linear pulse rate which is determined by data held in the memory of the microprocessor circuit. This data can be modified to suit the requirements of the stepper motor and load. Another program controls minimization of hysteresis by ensuring that each track on the disk is approached from the same direction and from the same previously energized set of windings. The microprocessor controls the direction of motion of the stepper motor and hence decides whether or not the read/write head should cross the desired track and return it to ensure uniformity of approach.

Title: Separating oil or bitumen from tar or oil sand
IPC: C10G1/04
Filed: 1982-05-12
Abstract: The separation of oil or bitumen from a surface (4) of a substrate (6) covered with same is effected by dissolving the oil or bitumen in a solvent to form a solution thereof. A liquid which does not dissolve the oil or bitumen, is non-miscible with the solvent and has substantially higher surface wetting properties than the solvent on substrate (6) is intimately contacted with the surface of the substrate (6); the solvent and liquid have substantially high interfacial tension relative to one another so as to form in the presence of the oil or bitumen an interfacial membrane-like barrier (8) which is impermeable thereto. The intimate contacting of this liquid with the surface of the substrate (6) causes the liquid to wet the surface and spread thereover to thereby move the interfacial membrane as it is being formed across the surface and displace with this membrane (8) the solution from the surface, and to finally cover the surface (4) with a layer of liquid; the membrane (8) maintains the oil or bitumen in the solvent and prevents passage of same into the layer of liquid. The method of the invention avoids the use of surfactants and the formation of emulsions, and thus the problems associated therewith. The invention finds a particular application in the recovery of oil and bitumen from bitumen covered tar sands and oil sands from oil wells.

Abstract: A layer of photoresist 16 having a generally flat surface is formed on a layer of PSG 15 having a projection thereon. A non-selective dry etching process using a reaction gas is effected in which a layer 16 and 15 are etched at equal rates. The etching process may be plasma etching using a mixture of a flouride compound gas and oxygen gas. Reactive sputter etching or reactive ion etching can also be used. The photoresist of layer 16 could be replaced by polyimide or liquid glass. PSG layer 15 could alternatively be a layer of polycrystal line silicon or wiring conductor. In each case, the use of a reaction gas mixture which ensures equal etching rates provides a flat surface at the finish of etching.
