Title: Improvements relating to hook fastenings for the waist-bands of trousers
Inventor: WALKER THOMAS
IPC: A44B13/00
Filed: 1955-10-18
Abstract: 791,407. Hook fastenings. WALKER, Ltd., T. May 3, 1956 [Oct. 18, 1955], No. 29623/55. Class 43 A back plate 1 for fitting into a pocket provided in a trousers waistband in order to secure by means of attachment prongs or the like a flat base plate carrying the tongue or hook of a hook-fastening, is characterized by an outer edge portion 8 which is folded over to form a narrow beading or rim 9 to engage the closed end of the waistband pocket. The strain occasioned by the pull upon a hook member secured to the back plate when the fastening is in use is thus taken up by the part of the pocket in abutment with the beaded edge 8. In the example the beading 9 is continued around the corners adjacent to the straight edge 8 of a substantially triangular back plate which is also formed with a rearwardly pressed circular rib 10 encircling the prong-receiving apertures 7. A circular opening 11 concentric with the rib 10 is provided to receive the ends of the prongs 6 on the base plate of a hook or tongue 3 when the back plate 1 is secured within a waistband pocket 4 by pressing the prongs through the material of the pocket and the apertures 7 and clinching them as shown in Fig. 6. In a modification, Fig. 8, (not shown), a beaded front edge is provided on a sheet metal back plate formed with prongs struck-up therefrom to engage within apertures in the base plate of a hook member.

Title: Flame-resistant acrylonitrile polymer compositions containing polybromocyclohexanes and calcium phosphates
Inventor: JR FRED JOHN LEWES
IPC: C08K3/32
Filed: 1965-07-14
Abstract: Flame-resistant articles are produced from a spinning solution comprising (1) an acrylonitrile polymer containing at least 85% acrylonitrile, any balance being another monoethylenically unsaturated monomer, dissolved in (2) an aqueous saline solution having dispersed therein (3) at least 10%, based on the weight of polymer, of a mixture comprising (a) a polybromocyclohexane having at least 3 bromine atoms in the molecule providing at least 3.5% Br2, based on the polymer weight and (b) a substantially water-insoluble calcium phosphate, the weight ratio of bromine to calcium phosphate being from 0.7:1 to 5.5:1. Zince chloride is the preferred saline solute. Specified acrylonitrile copolyers are those with vinyl chloride, vinyl acetate, methyl or other alkyl (meth)acrylates, the vinyl pyridines and allyl alcohol.  The polybromocyclohexane may be tribromotrichlorocyclohexane, tetrabromodichlorocyclohexane, pentabromomonochlorocyclohexane or hexabromocyclohexane, or mixtures thereof.  Tricalcium phosphate, calcium pyrophosphate and calcium metaphosphate are the phosphates specified.  A surface-active agent, e.g. a cationic, 70% active, reaction product of ethylene oxide, octadecylamine, octadecanoic acid and octadecyl guanidine may be incorporated in the spinning solution, as can plasticizers, lubricants, dyes and pigments.  In the example varying percentages of pentabromomonochlorocyclohexan and tricalcium phosphate are mixed with an equal weight of an aqueous ZnCl2 solution of polyacrylonitrile and with 2% of the said surfactant.  These concentrates are ground prior to mixing with further portions of the polyacrylonitrile solution and films are prepared from the resulting samples (see Division B5).

Title: Improvements in or relating to the production of silicon and semi-conductor materialmade therefrom
IPC: C30B9/12
Filed: 1957-09-25
Abstract: In the production of semi-conductor material by dissolving p material containing at least 86% Si, e.g. ferrosilicon at 700-1200 DEG C. in a metal melt, solidifying the melt by cooling to crystallise Si, and dissolving out the non-silicon ingredients to leave the Si crystals, the metal melt contains zinc and one or more of the metals alkaline earths, magnesium, tin, chromium, or aluminium acting as dopes.  Alloys, e.g. zinc-aluminium, or zinc-magnesium, may be used, and to produce n-type properties, the zinc may be used as zinc-antimony or zinc-arsenic alloy.  The silicon may be boiled or remelted in vacuum to remove any dissolved metal, or to control the amount of dope.  In an example, ferrosilicon is dissolved in a zinc-aluminium mixture in an atmosphere of N2, slag is removed, and the melt cooled.  The metal is dissolved from the solid residue with dil.  HCl to leave needles of silicon, which are washed in succession with HCl, water, H2F2, a mixture of H2F2 and HNO3, and water to remove metal solvent from their surfaces.

Abstract: 1,117,691. Filtration apparatus; spray-producers. INDUSTRIAL FILTER & PUMP MFG. CO. 16 July, 1965, No. 30382/65. Headings BID and B2F. [Also in Division F2] A filtration apparatus comprises a tank 20 containing a plurality of filter leaves 28 and a rotatable sluicing means 76, 77 having headers 76b, 77b which extend along the filter elements and have spaced outlet apertures from which jets of sluicing fluid are directed onto the elements 28 after a filtration cycle, the apertures being so arranged that on completion of the sluicing process the headers 76b, 77b may be brought into a position in which the apertures extend from the tops of headers which therefore remain full of sluicing liquid during the subsequent filter aid application and filtration cycles to exclude solid from apertures. In the embodiment of Figs. 1-11, 1, the elements 28 are fixedly mounted on a common outlet manifold 36, while headers 76b, 77b are rotated through an angle of 180‹ around the periphery of the elements 28 (Fig. 3, not shown). The elements 28 and the headers 76b, 77b are mounted on a removable end cover 25 of the tank 20, and may be lareely removed therewith by apparatus 47-61 after which an impacting device 33 engaging a bar 29 connecting the elements 28 at their upper edges may be used to shake dry filter cake from the elements. Headers 76b, 77b have outlet apertures arranged between adjacent pairs of elements 28, the outlet apertures being either holes (116) in combination with deflecting plates (118) (Fig. 6, not shown) or having mounted thereon spray nozzles (92) (Figs. 7-11, not shown). If elements 28 are cloth covered then the headers may carry nylon rollers (Fig. 5. not shown) bearing on the elements, or if the elements are of metal then the rollers may be replaced by U-shaped members (114) (Fig. 7, not shown). In an alternative embodiment (Figs. 12, 13, not shown) the filter leaves (136) are mounted to rotate with a central outlet header (138) under a single sluicing header (150), the header (150) being rotatable by a handle (164) to bring nozzles (174) from their upwardly facing position to a downwardly facing position for spraying sluicing liquid onto the rotating elements (136). The spray nozzle 92 (Figs. 9-11, not shown) comprises a central cylindrical bore (121) opening into a V-shaped groove (124) having an apex angle of 45‹ in the end of the spray nozzle. The bore (121) opens into the groove about half way up the side of the groove, forming a rectangular aperture whose length is half that of the groove. This construction provides a spray of rectangular section subtending angles of 120‹ and 15‹.
