Title: A method of preparing a plastisol
IPC: C09D133/06
Filed: 1979-09-20
Abstract: A plastisol is prepared from a paste-grade powder of a homopolymer and/or copolymer of vinyl chloride, vinylidene chloride or an acrylic compound and adhesion promotors containing amido and/or amino groups by dry heating the polymer together with 0.5 to 10% by weight of the adhesion promotor, based on the polymer, at a temperature of 100 to 180 DEG C, e.g. during spray drying, and then compounding the powder so obtained with a plasticizer. The plastisol obtained exhibits improved adhesion properties at lower baking temperatures.

Title: Forming of Sheet Metal
IPC: B21D5/01
Filed: 1979-10-03
Abstract: Metals such as titanium that exhibit little or no spring-back when held deformed at a suitable temperature are formed by being deformed into conformity with a single tool and held deformed while the tool is heated to or maintained at an appropriate temperature. Deformation may be produced mechanically, as by wrapping a flexible diaphragm about a male tool with interposed sheet blank, or by urging plunger 25 into female tool 20. Fluid pressure may deform a diaphragm to deform sheet blank into conformity with the tool. A tool for the method comprises a stack of shaped laminae. <IMAGE>
Patent GB-2061554-A (GB)
Title: Control System for Producing Crankshafts
IPC: G05B19/18
Filed: 1979-10-18
Abstract: Work-holders support a crankshaft 6 centered on a fixed axis and are rotated by first drive 7. A second drive 15 displaces a tool transverse to said axis. A first controller 17 is connected to the first drive and causes it to impart a desired angular movement to said work-holders. A second controller 18 is connected to said second drive and controls said displacement. Drive control computer means 19 process workpiece and tool data and compute increments of said displacement, and ranges of positions of said tool carriage. Interpolating means apply reference inputs to both said controllers in dependence points of inflection and characteristic values defining a series of linear approximations of a generally nonlinear relationship of the movements of the two drives. <IMAGE>
Patent GB-2037221-A (GB)
Title: Production of hot top slabs, e.g. for ingot moulds
IPC: C21D9/00
Filed: 1979-12-18
Abstract: The invention concerns a method and apparatus for producing curved hot top slabs, e.g. for ingot moulds, of a board material such as a composition of pearlite, a bonding agent of bitumen type and cellulose fibres. The slab (10) is first cut to the required size. The material of the slab is then softened by being saturated with an impregnating agent, e.g. in the form of colloidal silica in a water solution. At the same time, the impregnating agent increases the heat resistance of the slab. The slab (10) is then placed on a curved surface (11) where, either by the action of gravity or by a press platen (16), the slab is reshaped so that it rests on the support platen. While the shape of the slab is retained, the liquid phase is removed and the slab thus resumes its stiffness or even acquires improved stiffness as compared to the situation before softening and impregnation. <IMAGE>

Title: Head-supported Illumination Device
IPC: G02C11/04
Filed: 1980-05-20
Abstract: This invention relates to illumination devices of the type used by physicians and surgeons. Prior art illumination devices consist of a headband either supporting a conventional incandescent lamp and a reflector, or including light-conducting glass optical fibers and a remote light source to provide illumination. Illumination devices of both these types are much too heavy and cumbersome to wear for prolonged periods. The present invention provides an improved illumination device in the form of an extremely light-weight, high-intensity light- producing device utilizing polymer optical fibers to transmit light from a remote light source 30, and having a head-supported frame 10 of the eyeglass type, in which the fibers are terminated in two or more bundles 14 to provide a converging light pattern with minimal shadow effects. The remote light source employs a combination of dielectric mirrors 32, 34, (36) and a heat-resistant glass rod 38 to filter substantially all heat- producing infrared radiation from the light emitted by the source. <IMAGE>

Patent GB-2087978-A (GB)
Title: Fuel Control System for a Gas Turbine Engine
IPC: F02C9/28
Filed: 1980-11-26
Abstract: The system comprises a main controller (33) and an overspeed limiter (35) which provides a fail-safe should failure of the main controller (33) lead to an otherwise uncontrolled increase in fuel flow to the engine. In order to allow the limiter to reduce a maximum fuel flow to that required for safe operation at high altitude, while avoiding the possibility of a downward failure of the limiter at low altitude shutting the engine down, an input proportional to ambient pressure is used to control limiter operation. In the illustrated embodiment the ambient pressure input moves a three- dimensional cam (41) axially, the input dependent upon the speed of the engine rotor rotates the cam, and the output of radial motion of a follower (42) operates a fuel valve (44). <IMAGE>
