Title: Improvements in processes and apparatus for pneumatically opening fibre assemblages
IPC: D04H1/4382
Filed: 1966-03-24
Abstract: 1,143,937. Opening fibres; non-woven fabric. B. RUDLOFF. 24 March, 1966 [15 Oct., 1965], No. 12947/66. Headings DIN and D1R. Textile fibres particularly those to be used in forming a non-woven web, are opened pneumatically. As shown flock 2 is fed into a stationary feed table 3 which is curved to partly encircle a fluted roller 1 the pressure of which may be adjusted. Roller 1 feeds the fibres to be acted on by a first air jet 4 and then by a second air jet 5, the fibres thus being opened. The spacings 6 and 6<SP>1</SP> of the jets are adjustable. In Fig. 2, not shown, the fibres are fed along a tube (8) by a screw conveyer (7) to be acted on by a jet (9) directed along the axis of the tube. A casing (11) about the end of the tube provides a further air jet to act on the fibres, this jet has an adjustable pressure. In Fig 3, not shown, the fibres are fed by a belt (13) under a thickness regulating roller (14) and between fluted rollers (15, 16) to be acted on by a jet from a nozzle (17). In Fig. 4, not shown, fibres are fed between a feed table and fluted roller onto a cylinder (18) having saw teeth and are subsequently blown from the cylinder by a jet (19). Forming non-woven web. In Fig. 5, not shown, fibres are fed by an arrangement (21-25) to a station (A) to be opened by a device as shown in Fig. 1-4. The opened fibres then pass to a chamber (26) to be mixed with resin and formed into a web. The fibres are blown in by an air current (27) adjustable by a throttle (29) and means (28). The air is sucked back into a suction box 31 through a conveyor (30) so that fibres are brought into the conveyor. The fibres on the conveyor are evened by an air doctor (33) and engaged by a further conveyor (32) to pass through a heating tunnel to set the resin. The finished web is cut into lengths or wound up. Liquid resin may be carried to the fibres by the air currents in the fibre opening device or sprayed into chamber (26) via nozzles (34). Additives e.g. barium sulphate and asbestos, which may be mixed with powder resin can be fed in to the chamber by mechanical means (36). Air current (27) may be heated.

Abstract: 431,954. Bunch-building motion for ring and like frames. HURST, R. R., Merlin Grove, Smithills, Bolton. May 4, 1934, No. 13461. [Class 120 (ii)] In ring spinning-frames and the like auxiliary mechanism, comprising chains 26, 29 and bowls on a cross-shaft 23 connecting the building-motion lever 13 and a poker operating-lever 12, is adapted to impart a short reciprocating movement to the ring rails to wind the bunch, the main building-chain 14 connected to the lever 13 and the bowl 16 being inoperative during such movement. The chain 26 is connected to the lever 13 at a point near to the fulcrum. When commencing a fresh set, the ring rails being in their lowest doffing-position, the chain 29 is tightened by rotating the bowl 28 to a position determined by a stop-pin 34. The lever 13 is held against the heart-cam by means of a spring- connected catch rod 35, and, the chain 14 being slack, a reduced reciprocation is imparted to the ring rail to wind the bunch by the chains 26, 29. When the bunch is fully wound the chain 14 is tightened by rotating the bowl 16 so that the ring rail is raised and the normal chase imparted. The shaft 23 may be operated by a chain and quadrant lever engaged by the underside of the lever 13.

Title: Improvements in or relating to quartz to metal joints
IPC: C03C27/04
Filed: 1936-05-15
Abstract: 469,978. Uniting metal to vitreous material by heat. GENERAL ELECTRIC CO., Ltd. (Patent-Treuhand-Ges. f³r Elektrische Gl³hlampen) May 15, 1936, No. 13821. [Class 36] In making a gas-tight seal between quartz and metal, as in the manufacture of a highpressure mercury vapour discharge device wherein the vapour pressure is above five atmospheres, part of the surface of the quartz member is coatetl by a sintering process with a firmly adherent layer or a finely divided refractory metal to which the metal member is soldered. The refractory metal employed is preferably tungsten. The quartz surface is covered with tungsten powder and heated in contact with the powder to a temperature of 1500 to 1600‹ C. for a period of ten to fifteen minutes, so that the quartz is softened sufficiently for the tungsten crystals to embed themselves. The sintering process is carried out in a neutral or slightly reducing gas, for example a mixture of nitrogen with 1 or 2 per cent hydrogen. In one form of the seal wherein a conductor 5, Fig. 1, is carried through a quartz member 1 which has a hole fitting the conductor closely, the part of the quartz member around the hole is coated with a layer of sintered tungsten 2 to which a metal cap 4 is soldered by solder 3, the lead 5 being soldered or welded to the end of the cap 4. In contracting, after soldering, the cap grips the quartz so that, to avoid breaking, the walls surrounding the hole must be relatively thick. In another construction a metal tube 6, Fig. 2, soldered at one end to a layer of sintered tungsten 2, upon a quartz member 1 is sealed at the other end, in known manner, to a glass tube 7. Alternatively the metal tube 6 may be replaced by two flanged or socketed metal tubes which are first attached to the respective members 1, 7 and then welded or soldered together. The glass member 7 may be replaced by a ceramic member which can be sealed to the metal tube 6 by a process similar to that for sealing the latter member to the quartz member 1, or by a sealing - glass or enamel in known manner. When the layer of sintered metal consists of tungsten, and the metal member soldered thereto is of iron or its alloys, the solder may be silver or copper, or an alloy of silver and copper.
