Title: Extrusion of Plastics Material.
Inventor: BOUTILLIER PIERRE EMILE
IPC: B29C48/355
Filed: 1967-09-05
Abstract: 1,184,688. Extruding foamed plastics. UGINE KUHLMANN. 5 Sept., 1967 [7 Sept., 1966; 2 March, 1967], No. 40453/67. Heading B5A. [Also in Divisions C3 and F2] A hollow extrudate of foamable plastics is extruded from an extrusion head 4, Fig. 12, comprising a mandrel 5 into a temperaturecontrolled sizing die 7 where expansion of the plastics takes place inwardly of the extrudate to fill or decrease in volume cavity 15b. The nature of the final product, i.e. whether hollow or solid, depends on various parameters, chief amongst which is the draw-off speed of caterpillars 80. Sizing die 7 may be electrically heated, or as shown, have fluid-flow chambers 9; the temperature of the die in any event is maintained below the gelling point of the plastics and a smooth non-cellular skin 13 is formed on the extrudate. Suction may be applied to the extrudate via apertures in the sizing die, see Fig. 5 (not reproduced), and also to the cavity in the extrudate via a conduit in the die head mandrel, see Fig. 4 (not reproduced). In the embodiment of Fig. 12, the draw-off speed of caterpillars 80 is varied to produce a product having alternate hollow and solid portions. Hollow bricks may be formed by cutting into lengths such a product when of rectangular cross-section. In the embodiment of Fig. 6, a tube having a bore of constant cross-section is obtained by using an extrusion head having two mandrels 44b, 45 and a sizing die 47 having a single mandrel 47b, the separate layers of plastics formed by mandrel 45 expanding in die 47 to fill the cavity therebetween. Other embodiments describe the formation of a product of T-cross-section, Figs. 4 and 5 (not shown), and of rectangular or biconcave cross-section, Figs. 9-11 (not shown). Inward expansion of the extrudate may be on to a solid core, e.g. an electrical conductor. Plastics specifically mentioned are polystyrene, styrene acrylonitrile copolymers, acrylonitrile-butadiene styrene copolymers, PVC and mixtures of PVC with acrylonitrile butadiene styrene, polymethylmethacrylate, polyamides, polyethylene, polypropylene, polycarbonate, cellulose propionate and polyurethane. Twenty one examples are given and these include descriptions of the production of longitudinally ribbed rods and rods where such ribbing has been smoothed to give the surface a fibrous appearance.

Abstract: 1,201,331. Moulding test specimen of powder. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 5 Sept., 1967 [13 Sept., 1966], No. 40824/66. Heading B5A. [Also in Divisions G2 and H1] A method of spark source mass spectrometric analysis of a powder material comprises the steps of preparing a coherent sample of the powder material, e.g. graphite, by placing the powder in a chamber in a member D of deformable but substantially incompressible plastics material, arranging the member D in the die A of a punch and die set which is then used to compress the plastics member and the powder therein, and using the compacted powder sample thus formed as an electrode in a spark source mass spectrometer to obtain a mass spectrometric analysis of the sample material. The member D may have an open powder chamber which may be closed by a plastics covering within the die prior to the compression, which may for example amount to 70 tons/sq.in. The plastics member D may be made of a pure hydro-carbon which is resiliently deformable, e.g. polyethylene, and may contain more than one powder chamber.

Abstract: 1,130,334. Thermocouple assemblies. G. V. PLANER Ltd. 17 Dec., 1965 [8 Oct., 1964], No. 41129/64. Heading H1K. In making a thermocouple assembly thermoelements are assembled in side-by-side relationship and bonded together by glass or ceramic material which serves to mutually insulate them. Typically bars 15 (Fig. 3) alternately of P- and N-type conductivity material are assembled in the meshes of wire grids 19 in a mould 22 and the assembly impregnated with ceramic cement or molten glass. Alternatively glass or ceramic coated elements are assembled row by row between two sets of parallel wires, other wires being inserted across the two sets of wires between rows as they are formed. The assembly is then consolidated by heating. In both cases, after consolidation the assembly is removed from the mould and the ends ground down to remove the wires or grids. A chequerboard arrangement of bars can alternatively be made by first assembling sheets alternately of P- and N-type in a pile interleaved with glass sheets or glass or ceramic cement and heating to consolidate. The resulting assembly is sliced along planes transverse to the sheets and the slices suitably reassembled in a pile with further interleaves of glass, and consolidated by heat. Bismuth telluride, lead tin telluride, and a mixture of germanium telluride and silver antimony telluride are suitable thermoelement materials. Nickel or iron may be flame sprayed through masking to form direct interconnections between adjacent elements or connections between iron or nickel cups embedded in the bars before assembly. Such cups may alternatively be joined by electroplating or welded on links.

Title: Fuel Systems for Gas Turbine Engines

Abstract: 1,156,462. Gas turbine engine fuel systems. JOSEPH LUCAS (INDUSTRIES) Ltd. Nov. 4, 1966 [Oct.7, 1965], No.42563/65. Heading F1G. A gas turibe engine fuel system comprises a throttle 14 controlled by a manual lever 21 and also by a means 39 responsive to a pressure which varies with that in the engine intake, a cam 44 connected to the throttle and acting through a spring 46 upon a valve 48, which is arranged to modify the response of the means 39 to the pressure, and a means 50 responsive to changes in engine speed and acting on the valve 48 in opposition to the spring 46. The arrangement is such that manual opening of the throttle 14 increases the load exerted by the spring 46 to actuate the valve 48 to modify the response of the means 39 so as to tend to close the throttle, the resultant force on the throttle causing its opening rate to be controlled until the engine speed increases to an extent to actuate the valve again, whereupon equilibrium conditions are obtained to maintain the engine speed at a new value. Fuel is delivered by a swash-plate pump 10 via the throttle valve 14. The pressure drop across the valve 14 is maintained constant by a valve 16 subject to the pressure drop and acting to control the escape of fuel from a servo-mechanism 17 which controls the pump stroke. The means 39 comprises a piston subject to the fuel pressure upstream of the throttle 14, directly on one side of the piston and via a restirctor 40 on the other side. The pressure downstream of the restrictor 40, and hence the position taken up by the piston 39 in opposition to a spring 43, is varied by a valve 37 connected between the restrictor and the pump inlet passage 11. The valve 37 is actuated by an evacuated bellows 35 opposed by the spring 43 and acted on by a pressure intermediate atmospheric pressure and the engine intake pressure and derived from the latter pressures by a potentiometer 33, 34. The means 50 responsive to engine speed comprises an evacuated bellows acted on by a pressure proportional to the pressure rise across the engine compressor (and therefore proportional to engine speed) derived by a potentiometer 54, 55 connected between the inlet and outlet of the compressor. The linkage connecting the manual lever 21 and the piston 39 to the throttle 14 is preferably such that it can occupy a position in which the manual lever 21 has no effect on the throttle 14 and a further position in which the piston 39 has no effect on the throttle. This linkage is described in Specification 1, 128, 524.
