Title: Multi-layer sintered products having a foamed layer and methods of making them
IPC: B29C39/00
Filed: 1966-02-18
Abstract: 1,129,127. Powder sintering. SUMITOMO CHEMICAL CO. Ltd. 18 Feb., 1966 [27 Feb., 1965], No. 7239/66. Heading B5A. Multi-layered thermoplastic resinous articles including one foamed layer, are formed by powder sintering successive layers in a heated metallic mould, the material forming the foamed layer incorporating a foaming agent decomposable at a temperature higher than the melting point of the material. In one embodiment, to form a three layered article, resin powder is fed to the mould, sintered to form a layer and the excess removed. A powder including a foaming agent is then fed to the mould, heated to form a sintered layer and the excess removed, and subsequently heated to a higher temperature to completely decompose the foaming agent and form the foamed layer. A third sintered layer is then applied in the same manner as the first and the whole then heated to smooth the surface of the article. If the third layer is sufficiently thin then it may be sintered by the residual heat retained by the mould and the first two layers the article being smoothed as before. In a second embodiment the first layer is applied as before and then a sintered foamable layer is formed which layer is then heated to partially decompose the foaming agent. The third layer is then applied as before and the whole finally heated to fully decompose the foaming agent and to smooth the surface of the article. Two layered bodies are formed by merely omitting the last layer.

Abstract: 1466399 Spinning and finishing yarns HOECHST AG 18 Feb 1974 [19 Feb 1973 (2)] 7326/74 Headings D1F and D1W In the manufacture of a smooth or bulky multifilament yarn having individual filaments ends protruding from the main body of the yarn, an undrawn or partially drawn yarn of spun filaments of a synthetic polymer material e.g. polyethylene terephthalate, polyamides, polyolefins, polyacrylonitriles, celluloses and copolymers and derivatives thereof, at least some of which have "a bending- breaking-stress stability" of less than 1500 cycles -as measured by a described wirebending device, Fig. 4 (not shown)-is subjected to a bending and/or twisting stress acting transversely and sufficient to break these filaments at irregular intervals. The specified filaments may be mixed with filaments of greater "stability" e.g. in a ratio range of 7:3 to 3:7, which are not broken by the applied stress(es): Yarn may be stressed by turning it around a guide pin of small diameter and/or by twisting as in a false-twist texturing operation (perhaps combined with a drawing process) or by draw-twisting. The yarn may be after-treated to improve the filament bonding e.g. by at least temporarily interlacing the protruding ends by means of a gas jet or sizing. Component filaments in a yarn may differ as regards titre, cross-sectional form, colour, crimp potential, flame resistance and may be bi-filar. Fabrics knitted or woven from the yarn exhibit a marked resistance to pilling, Fig. 1 (not shown).

Abstract: 1456303 Wrapping articles EMHART CORP 19 Feb 1974 [20 Feb 1973] 7580/74 Heading B8C Apparatus for forming a box around an array of articles includes a vertically reciprocable mandrel 52 for forming a flat blank into a U-shape, and a vertically reciprocable, inverted U-shaped member 20 which moves an array of articles on to the U-shaped blank. Both the mandrel 52 and member 20 are mounted on a horizontally reciprocable carriage. In the embodiment shown the member 20 moves two layers of articles on to the blank, the top layer being held by suction while the bottom layer is formed on a lift table 16. An intermittently driven conveyer has pockets constituted by rear and front members 40, 42 mounted on different chains 36, 38 for adjustment on the spacing of the members. At a forming station 34 the mandrel 52 shapes the blank between pocket members 40, 42, the U- shaped member 20 moves the articles from the table 16 on to the shaped blank, and a device 60 folds the rear side flaps of the blank. As the conveyer advances the front side flaps are folded by rails 64, the top panel is folded downwardly and ploughs 70, 72 fold the top and bottom side flaps. Adhesive may be applied to the side flaps. When the box reaches a dead plate, adhesive is applied by a device 73 to the manufacturers flap which is then folded down, the succeeding boxes holding the flap down until the adhesive has dried. In another embodiment the member 20 moves a single layer of articles on to the blank and has cams on its side plates to stagger the articles in one row with respect to the articles in adjacent rows. The rows are moved together by conveying plates as the member 20 moves towards the blank.

A clamp bar 24 is disposed in the channel 16 and has re-entrant cam notches 25 in the upper part of which the projections 17 fit, the lower walls of the notches being inclined so that upward movement of the bar 24 forces the bar outwardly to clamp the post P. At the bottom of bar 24, a bolt 27 is threaded into a bore 26 and initially is arranged so that the projections 17 are in the upper part of notches 25 when the head 28 of the bolt is touching the base 11. The post P is then slid over the upright 12 and bar 24 and the bolt 27 rotated to move the bar 24 upwardly, the cam notches moving the bar outwardly to clamp the post. An adjustable support plate 18 is provided so that with uneven floors, the posts P may be supported at the same level. The plate 18 is U-shaped and the arms 19 straddle the upright 12 and the cross portion 20 engages the up-. right. In this position, in which the post P rests on the plate 18, a threaded aperture 21 in the plate overlies an aperture 14 in the base 11 and a bolt 22 is threaded through the aperture 21 and its reduced end 23 engaged in the aperture 14 so that plate 18 is horizontally supported at any required elevation. A foot sleeve S gives a finished appearance to the post and holes 13 are provided in the base 11 for screws or bolts for securing it to the floor. Specification 784,298 is referred to.

Abstract: 273,660. Daloze, R. July 3, 1926, [Convention date]. Lead carbonate; lead acetate.-Crude lead sulphate and an excess of an alkaline earth acetate in solution are mixed and the insoluble matter separated, whereon the clear solution is treated with a base to form tribasic lead acetate in solution, which is decomposed by carbon dioxide to yield lead carbonate. The excess of calcium acetate is such that, after separating precipitated calcium sulphate, on adding calcium hydrate and precipitating lead carbonate with carbon dioxide, the original solution of calcium acetate is reformed. The solution may contain three equivalents of calcium acetate to one of lead acetate, and react with two equivalents of lead sulphate. Any iron present may be filtered off as insoluble tribasic iron acetate.

Abstract: 539,871. Multiplex telegraphy ; synchronous movements. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. April 29, 1940, No. 7661. Convention date, April 29, 1939. [Class 40 (iii)] Relates to distributer systems in which one channel is used for code signalling and other channels are used for teleprinter working. At each station two distributers are used, one having a number of segments a, b, c equal to the number of channels (three), multiplied by the number of code units per character in the teleprinter system (seven being shown), the segments c associated with the Morse code signals being dead ; the other distributers D, Fig. 1, and F, Fig. 2, being in series with the first but having only three segments. The distributers C, D at the transmitter are synchronized so that the brush 13 of distributer D engages segment 12 connected to the Morse transmitter 9 at instants wherein brush 8 of distributer C is passing over the dead segments c. Morse signals are thus interspersed among the teleprinter signals from channels A, B. An additional brush 15 energizes the tape feed magnets 1 in turn. At the receiver, the signals are distributed by brush 27 of distributer F to the Morse code channel 45 and to a relay 48 which repeats them over the segments of distributer E to the teleprinter relays of channels A, B. After each half cycle of distributer E, brush 53 energizes the printer magnets 54, 56 respectively. The distributer E is driven by a motor 40 controlled by a commutator 38 on the shaft of distributer F, which is driven by a motor 31 supplied from a constant-frequency source 32 and synchronized by a unit 26 associated with additional distributer segments 36 and brush 34. Units 45, 47 are locking circuits as described in Specifications 346,607 and 348,858 which prolong the received pulses until a fresh signal is received. Specifications 480,150 and 526 988 also are referred to.
