Title: Improvements relating to wave measuring buoys
Inventor: CROWTHER PAUL ANDREW
IPC: G01C13/00
Filed: 1969-01-10
Abstract: 1,249,035. Buoys. ELLIOTT BROS. (LONDON) Ltd. 9 Feb., 1970 [10 Jan., 1969], No. 1538/69. Heading B7A. [Also in Division G1] Water surface excursions are measured by supporting on a buoy a number of probes 3 which are arranged to be partially immersed in the water, a damping board 5 being provided on the buoy and being arranged at a depth below the surface such that the buoy follows vertical excursions of relatively long wavelength waves to thereby maintain partial immersion of the probes but not vertical excursions of relatively short wavelength waves. In this manner small waves superposed on large waves may be detected and measured. The probes may be resistors or capacitors and may be arranged in a two- or three-dimensional array. A housing 1 contains electronic equipment (including a local oscillator, filters and head amplifiers) and instruments for measuring the orientation and motion of the buoy (including vertical accelerometer, pitch/ roll sensors, and electronic compass sensor). Data may be transmitted to a recording station by cable or radio.

Abstract: 1,060,212. Grinding. CARBORUNDUM CO. Ltd. Jan. 12, 1966 [Jan. 14, 1965], No. 1764/65. Heading B3D. A method of manufacturing an abrasive honing stone for mounting in a shoe comprises coating the shoe contacting surface of the stone with a hot melt adhesive. The adhesive may be any natural or synthetic polymeric material, such as polyvinyl butyral or polyvinyl acetate used either separately or in admixture, which softens at elevated temperatures sufficiently to wet and adhere to the surface of the shoe. The shoes may be warmed on a hot plate to 120‹ C. and the adhesive coated faces of the hones pressed into contact with the shoes. Plasticizers and tackifiers may be included in the adhesive which may be produced by dissolving solid polyvinyl acetate in a mixture of acetone and ethylacetate to which a filler, such as iron or chrome oxide is added. The adhesive may be applied in the form of a solution which is removed by air drying or heating.

Patent GB-727582-A (GB)
Title: Improvements in or relating to recovery of gold from cyanide solutions
Inventor: BURSTALL FRANCIS HEREWARD
IPC: C01G7/00
Filed: 1952-01-22
Abstract: Gold absorbed as aurocyanide on a strongly basic anion exchange substance is recovered by extraction with an organic solvent containing a minor proportion of an inorganic acid.  The strongly based anion exchange resin may be an artificial resin of the amine type, for example, "Amberlite IRA 400" (Amberlite is a R.T.M.). Solvent-acid mixtures specified are acetone-hydrochloric acid, ethyl acetate-nitric acid, ethyl alcohol-hydrochloric acid and methyl alcohol-hydrochloric acid.  A small proportion of water may be present in the mixture.  At least part of any copper and iron present with the gold may be removed by a preliminary elution with an aqueous solution of an alkali metal cyanide.  At least part of any nickel and zinc present may be removed by a preliminary elution with a dilute aqueous mineral acid solution.  The elution with aqueous alkali metal cyanide solution may follow that with aqueous mineral acid.  But where copper is present in great excess of the gold a preliminary elution with 2M sodium cyanide should be carried out to remove the majority of the copper prior to any elution with dilute aqueous inorganic acid.  The solution of gold obtained by the invention contains substantially all of the impurities remaining after the preliminary treatments except any cobalt and possibly some of any silver present which may be finally removed from the resin by means of an aqueous 2M potassium thiocyanate solution, leaving the resin ready for further use. The gold may be absorbed on the resin from an aqueous cyanide solution and, where the proportion of gold contained therein is small, the processes of absorption and preliminary elution may be repeated a number of times before the gold is extracted from the resin.

A fluorocarbon polymer containing at least 0À1 mole per cent difluoroketene units of formula -CF 2 -C(O)-, is prepared by reacting a finely divided fluorocarbon polymer starting material containing alkyl trifluorovinyl ether units of formula -CF 2 -CF(OR)-, where R is an alkyl group, with a Lewis acid in the liquid state which is sulphur trioxide, aluminium trichloride or titanium tetrachloride in an inert liquid medium, whereby sufficient of the ether units are converted to difluoroketene units to provide at least 0À1 mole per cent difluoroketene units in the polymer, the presence of the liquid medium being optional when sulphur trioxide or titanium tetrachloride is used as the Lewis acid. The fluorocarbon polymer is either a homopolymer consisting substantially of difluoroketene units or a copolymer containing at least 0À1 mole per cent -CF 2 C(O) units, the remainder being units derived from perfluoro - 2 - methylene - 4 - methyl - 1,3 - dioxolane (PMD) and/or an alkyl trifluorovinyl ether and/or a perfluorinated hydrocarbon. The fluorocarbon polymer starting material is either a homopolymer consisting substantially wholly of alkyl trifluorovinyl ether units or a copolymer consisting of alkyl trifluorovinyl ether units and units derived from PMD and/or a perfluorinated hydrocarbon. The liquid medium is any medium consisting of a perfluorocarbon, a perchlorofluorocarbon or any mixture thereof. In the examples, methyl trifluorovinyl ether, tetrafluoroethylene, PMD and n-butyl trifluorovinyl ether are homopolymerized and copolymerized in the presence of CCl 2 FCClF 2 , perfluoropropionyl peroxide and (C 2 F 5 COO) 2  and the polymers treated with sulphur trioxide, aluminium trichloride and titanium tetrachloride in CCl 2 FCClF 2 . The polymer starting materials may be reduced in particle size by shearing in a blender, optionally in the presence of a fluorinated cyclic ether of formula C 8 F 16 O.

Abstract: 1,130,432. Making coated rod and wire. COPPERWELD STEEL CO. 19 Jan., 1966 [26 Jan., 1965], No. 2563/66. Heading B3A. [Also in Division C7] In a continuous hot dipping process of cladding continuous lengths of metal rods such as steel with e.g. Cu, Al or Zn, the rod is passed in a straight pass line through a heating zone where it is heated to a bonding temperature below the melting temperature of the cladding metal, then through a bath of the molten cladding metal and finally through a heated sizing die. As shown in Figs. 1 and 2 welding of the ends of the coils is effected at 14 and the rod is passed through a multiplane roller straightener 17, a grit blaster 20 through which it passes twice via sleeves 21 and 23, then via pinch rollers 25 to a second straightener 26 and into vertical grooved entry rolls 27. The straight rod then passes through preheating furnace 29, preferably an induction furnace where it is preheated to 1400-1600 F. and then into the hot dip furnace 30 which contains molten copper at 2000-2100 F. The clad rod passes through a heated sizing die 31, a vertical roller guide 39 and then into a torque controlled pulling device 43. Quenching may be carried out at 48, 49 and a continuous annealing furnace may be included in the process line. Between quenching tank 49 and coiler 53 a slack span is formed in the rod 44 in the form of a downwardly convex bow. The tension is controlled by switch 50 and arm 51 resting on the bow. In order to maintain the pass line of the rod straight and level, the dipping furnace 30 is mounted on an adjustable table 33 supported by stand 34 so that die 31 and the entry guide from preheater 29 to furnace 30 can be precisely aligned with the pass line of the moving rod. The inlet guide to furnace 30 and the inner end of the die 31 project into furnace 30 and are below the level of the molten metal. A protective gas (N 2  + H 2 ) enters the exit end of preheater 29 and passes countercurrent to the rod.
