Title: Extrusion apparatus
IPC: B29C48/335
Filed: 1974-07-10
Abstract: 1438431 Cross-feed extruder die W HEGLER 10 July 1974 [22 March 1974] 30631/74 Heading B5A A stream of plastics material, e.g. rigid P.V.C., being delivered as a solid section stream at an oblique or perpendicular inlet 9, Fig. 1, to a cross-head tube extrusion die is divided transversely of the stream into a stream of U-shaped cross-section which is delivered to the exterior of a mandrel ring 6, around which the arms of the U flow in opposite directions to recombine as an annular stream discharging to a tubular outlet. The mandrel ring 6 is secured by bolts 17 at a conical interface within an outer die part 5, and division of the stream is effected within the part 5, Fig. 5, by a machined splitter part thereof comprising an upstream stream splitting edge 8 continuing downstream as a U-shaped surface 7, of continuously increasing size, to a U-shaped passage junction with the mandrel ring 6 around a mandrel surface 13, Fig. 7. The arms of the U-shaped stream flow around a recessed surface 14 of the mandrel ring 6, to recombine as the annular stream at location 15. The splitter part of the die part 5, and the mandrel junction passage around the surface 13, are simultaneously machined with the part 5 and ring 6 assembled, by a machine tool operating through the upstream inlet 9 of the part 5, along a U-shaped path of continuously increasing size. After polishing, the ring 6 is disassembled for machining of the recess 24. The cross-head may be employed for extruding the tube around a cable or, as shown in Fig. 1, around an inner concentrically extruding tube into a continuously moving corrugating mould. In the Fig. 1 apparatus, the die 4 defining the extrusion passage for the outer tube is transversely adjustable by three screws 21. For adjusting the extrusion passage for the inner tube, the mandrel 22 defining the passage locates against its surrounding die 3 at four co-planar studs 23, which are screwed or press-fitted into the mandrel 22 midway of its length and extend across the extrusion passage into engagement with the die 3 at conical interfaces facilitating disassembly. The studs 23 are cigar-shaped in the extrusion direction, and provide a fulcrum about which the mandrel 22 is adjustable, by three adjusting screws 25 which extend through the die 3, to bear upon the upstream surface of the mandrel 22. A mandrel passage, 26 is provided for introducing supporting air into the extruding inner tube.

IPC: D01F2/30
Filed: 1927-12-23
Abstract: 314,414. British Celanese, Ltd., Payne, R. W., and Roberts, R. P. Dec. 23, 1927. Cellulose esters and ethers, processes for making filaments from.-Artificial silks exhibiting a reduced lustre lor even a dull matte lustreless appearance, are obtained by the dry-spinning of solutions in volatile solvents of cellulose acetate or other organic acid esters of cellulose or of cellulose ethers, the solutions containing such a quantity of water and the spinning conditions being so chosen that the water exerts a precipitating action on the cellulose acetate &c. during the early stages of filament-formation. The quantities of water employed are preferably 20-30 per cent of the quantity of volatile solvent; the degree to which delustring takes place depends on the proportion of water added and the temperature of spinning, being generally greater as the proportion of water is higher and the temperature of spinning is lower. Specification 209,125 is referred to.

Title: Improvements in lamps
IPC: F21S8/10
Filed: 1937-11-10
Abstract: 494,457. Vehicle, flying-ground, &c. lamps. BORMANN, O. Nov. 10, 1937, No. 30904. Convention date, Nov. 12, 1936. [Classes 75 (ii) and 75 (iv)] In a vehicle lamp, a lamp for illuminating flying-grounds, or other lamp for illuminating roads or large areas, an image of the aperture of a condenser system, or of the light-outlet aperture or apertures of a stop arranged in front of that system, is formed by an objective of great focal length that forms sharp images of lines in one direction, e.g. horizontal lines, but indistinct images of lines at right-angles to the first direction, e.g. vertical lines. In the form shown, the condenser sytem associated with the light source 1 comprises three lenses 2 and associated spherical mirrors, and prisms 3 which redirect light from two of the lenses 2 forwardly. A stop 5 in front of the condenser system has three rectangular apertures. The objective may, as shown, comprise a lens 4 with vertically extending grooves 6 which prevent the formation of sharp images of vertical lines. Alternatively, the grooves may be formed on a glass disc separate from the lens, or a piano-spherical lens may have associated therewith a cylindrical lens, or the lens may have one surface spherical and the other cylindrical. The objective may comprise two lenses arranged with their centres separated by the width of an aperture of a stop 5, so that two sets of images of the apertures in the stop 5 are formed. The grooves 6 or their equivalent cause these images to run into one another and form a continuous band of light. The upper edge of the apertures in the stop 5 may be toothed, so that the lower edge of the image formed by the objective is not sharp.

Title: Fluid control valve
IPC: F16K31/12
Filed: 1962-08-14
Abstract: 1,017,397. Valves. SENCO PRODUCTS Inc. Aug. 14, 1962 [July 9, 1962], No. 31126/62. Heading F2V. A valve 37 for controlling the applications of fluid under pressure to the piston 48 of a stapler comprises a piston having a limited axial movement within a chamber and two sides of different area so that equal fluid pressure applied to both sides moves the piston in one direction while reduction in pressure on the side of greater area causes the piston to move in the opposite direction, the smaller-area side of the piston forming a valve member to cooperate with a seat 29. When a manuallyoperated lever 24 raises a pilot valve 22 communication between an air supply chamber 13 and the space above the valve member 37 is interrupted by lands 22 closing ports 20. Further upward travel of the pilot valve connects the ports 20 with exhaust passages 56, 57 so that the pressure in the chamber 13 acting on the lower side of the valve member 37 lifts it from the seat 29, the movement being accelerated once the valve is clear of its seat. The air supply now forces the piston 48 and its driver 49 down on to a resilient stop 46, uncovering ports 53 to permit air to flow past a reed 54 into a storage space 51. When the lever 24 is released, air in chamber 13 forces the pilot valve downwards and again enters the space above the valve 37 which has an interior seal 40 co-operating with a fixed stem 33 provided with exhaust ports 43. The latter are thus opened and air from the storage space 51 flows through passages 52, 47 to raise the piston 48 to its original position where it may be held by a spring detent in a magnet. An insertion washer 41 mounted for relative movement on the valve 37 co-operates with the seat 29.

Turning-gear.-In a starting-handle prevented from backward rotation by an automatically disengaging ratchet mechanism i coupling the handle q to its shaft a and enclosed in a casing d, the handle is connected by a pawl s and ratchet r to a sleeve b<1> and a friction coupling m is interposed between the sleeve b<1> and the shaft a in order to prevent the sudden release of the starting handle. As shown, the conical friction member m is connected to the shaft a bv a sliding key o and is held by a spring n in engagement with an internally coned member b<2> screwed into the sleeve b<1>. The shaft a and member b<2> are also coupled by a ball or roller i engaging a recess l in the shaft, a slot in an extension k of the member b<2>, and a recess h in a. member e connected by free-wheel rollers f to the fixed casing d. At starting, the shaft a is moved axially into engagement with the engine shaft. If the engine turns backwards, rotation of the member e is prevented by the free-wheel rollers f, and the ball or roller i is forced into the recess h and ceases to couple the part b<2> to the shaft a; these parts are then connected only by the friction coupling m, which slips but prevents the sudden release of the starting-handle.
