Title: Improvements in the treatment of textile fabrics
IPC: D06M15/263
Filed: 1962-05-22
Abstract: A flexible, porous, abrasion-resistent woven fabric suitable for use for vehicle upholstery is produced by treating a woven fabric with a polymeric composition in such a manner that the uppermost fibres only of the yarns forming the face of the fabric are tightly bound together and a substantial but evenly distributed proportion of the yarns of the face are free to move relative to adjacent yarns.  The face and backing yarns of the fabric may comprise continuous filament or spun yarns and may comprise viscose rayon, polyamide, polyester, acrylonitrile polymer or copolymer, polyethylene polypropylene polyvinyl chloride, polyvinylidene, cellulose acetate, ethylcellulose cotton flax, jute, hemp, ramie, paper, wool, alpaca, vicuna, mohair, cashmere, guanaco, camel's hair, silk llama yarns.  The polymeric material applied may be a copolymer of acrylic acid with methyl or ethyl acrylate, polyvinyl chloride, polyvinylidene chloride, a polyvinyl ether, polyvinylacetate, polyacrylonitrile, abutadiene-styrene copolymer, a polymethane, an epoxy resin a polyester a polyamide or a polycarbonate and may also contain small amounts of an aminoplast or phenoplast.  The polymeric composition may be applied to the fabric as an aqueous solution or emulsion or dissolved or emulsified in an organic medium, e.g. methanol or ethanol, by spraying or by means of trough apparatus comprising an open-bottomed trough buried with a porous material, preferably of nylon, so that the porous extends through the open-bottomed trough to form a bag-like protuberance and through which the polymeric composition is released in small amounts when contact is made with the fabric treated, the flow of the polymeric composition optically being controlled by placing a synthetic sponge in the opening in the trough separating the nylon bag and the trough.  After the application of the polymeric composition the fabric may be dried rapidly by flash drying at 100 DEG -200 DEG C. by means of hot air ovens or infra-red lamp arrays the fabric preferably being supported on a cool glass plate.  Hot air may be blown from the backing through to the face of the fabric forcing the polymeric composition towards the face of the fabric. A small amount of migration of the polymeric composition into the backing yarns of the fabric is permissible provided the fibres in the backing yarns are no more than loosely held together and the backing yarns remain free to move relative to adjacent fibres and yarns.

Abstract: 755,291. Nuclear reactors. SOC. RATEAU. July 7, 1954 [July 10, 1953], No. 19917/54. Class 39 (4). A nuclear reactor is cooled with a fluid which flows from the periphery inwards and then flows along channels with maximum rate of flow through the central channels. Coolant admitted at d<SP>4</SP> into an annular space d<SP>3</SP> flows centripetally between vanes d<SP>5</SP> into a slot c which divides the reactor into two halves a<SP>1</SP>, a<SP>2</SP>. From the slot c the coolant flows along channels b<SP>2</SP> to outlets el, e<SP>2</SP>. The static pressure in the slot c is greatest in the centre, and maximum rate of flow is therefore produced in the central channels. To ensure uniform heating of the cooling fluid the spacing of the channels may be varied, throttling may be provided at the inlet or outlet ends of the channels b<SP>2</SP>, or the slot c may vary in width as shown in Fig. 3. In a modification, Fig. 4 (not shown), radial partitions divide the slot c.

[Also in Group XXIX] In a grinding machine having a rotatable grinding disc the grinding surface of which is adjusted by means of a dressing tool to a constant location relatively to a workpiece being treated, a workpiece is placed in a measuring device and the position of the dressing tool is adjusted by means of a servomotor receiving impulses from the measuring device in response to the dimensions of the workpiece. A workpiece 10 in a chuck is ground internally by a grinding disc 14 which is fed radially until the radius of the bore slightly exceeds R ; the disc is then withdrawn past a diamond dressing tool 18 set at a distance R from the axis of the workpiece, and is then reintroduced into the bore, the disc being given a final predetermined radial feed k to bring the bore to the desired size. The diamond tool 18 is carried by a slide 22 movable, relatively to frame 20, by a screw 24 having a manual adjusting head 26 and a ratchet wheel 28 with which co-operate pawls 30, 32 carried by an intermediate member 34 of a differential pressure gauge comprising bellows 36, 37. Fluid under pressure is supplied through conduit 46 and on-off valve 48 to a valve housing 60 containing a valve controlling the supply through pipes 72, 74 to the bellows 36, 37.

If the workpiece internal diameter is incorrect, the member 34 moves a distance corresponding to the error and effects the necessary adjustment of the diamond tool 18.

Abstract: 1423013 Electroluminescence NORTHERN ELECTRIC CO Ltd 22 Feb 1973 20126/75 Divided out of 1423011 Heading C4S [Also in Divisions F4 and H1] A solid state light-emitting device (e.g. for signal and indicator lamp applications) comprises a semi-conductor electroluminescent element mounted at the focus of a parabolic reflector 6, a transparent insulating material 4 encapsulating the electroluminescent element, material 4 being formed with a polylenticular lens formation on the front face. The lens formation may comprise a plurality of convexities or concavities. Fig. 1 includes PN device 1 (e.g. GaP : Zn, O), electrical leads 3, and capsule 4 of clear or coloured transparent thermosetting resin suitable for transfer moulding (e.g. epoxy, silicone, polyester or diallylphthalate resin). A red colour is suitable for GaP : Zn, O s/c. After moulding the parabolic surface may be vacuum metallized with Al, a base coat being applied before and a protective top coat after. The reflector may be formed separately from the capsule, mounted, and encapsulated (e.g. Figs. 3, 4, not shown). This is particularly suitable as an indicator lamp for a telephone set, and is visible at any angle up to 45 degrees from the normal. Pedestal 11 ensures no light is reflected on to the central part of face 12 already illuminated directly. The lamp is circular and the reflector a paraboloid rather a parabolic cylinder as in Fig. 1 for example. The lamps are preferably moulded with front face 12 down so that any imperfections occur on the back. Inclined peripheral portion (18) causes a small part of the light to emerge at approximately 90 degrees to the vertical axis of the lamp. Figs. 5, 6 (not shown) are a key telephone push-button with two lamps as in Figs. 3 and 4, and contrast enhancing filter (23) (e.g. a red circular polarizer). To distinguish which lamp is signalling, flat diffusing inwardly inclined surface (25) is provided to scatter light from conical section (18). Figs. 7, 8 (not shown) include central conical recess (30) surrounded by series of concentric annuli of concavities (31). The arrangement increases the effective size of the lamp. The angle subtended by recess (30) is chosen to reflect incident light from the top surface of element (1) outwards to reflector (6). Recess (30) produces a dark centre. Fig. 9 (not shown) includes convexities (35). If the s/c elements emits non-visibly, an up-converting phosphor (e.g. infra-red to visible) may be coated directly on the element, or on a further support.

The first solution contains CaCl 2 , HCl, SrCO 3 , CdCO 3 , SbCl 3  or Sb 2 O 3  and MnCl 2  or MnCO 3 . The second solution contains (NH 4 ) 2 HPO 4  or H 3 PO 4 , NH 4 F and NH 3  and the medium NH 4 Cl and 1-12% of the second solution. The medium is maintained at 55-75‹ C. with a pH of 4 to 8À5. To achieve different rates of dispersal of alkaline earth and phosphate ions the solutions are introduced into different regions of the medium which is stirred by means at the centre or side of the container. Alternatively the first solution is introduced as a jet. A precipitate forms of 3 to 30 micron particles each shaped like a bunch of grapes. The particles are heated at 1050-1200‹ C. in boats pushed through a furnace in a N 2  stream. The resultant phosphor contains less than 3% Ca 3 (PO 4 ) 2 . The SbCl 3  may be replaced by Eu 2 O 3 .
