Abstract: 788,204. Covering elongated cores. KRAFT, J. Dec. 5, 1955, No. 34811/55. Class 109 In a spinner device for covering electric conductors or other cores with insulating or other material, the supply of covering material revolves coaxially with the spinner relatively to the spinner head against the resistance of a brake and a pre-settable tensioning devÝce is coupled to a pair of interlinked double-armed levers which carry rollers about which the material can be passed and which are adapted to swing towards and away from one another to adjust the relative speeds by controlling the resistance of the brake so that an increase in tension of the material from the supply loosens the brake and vice versa, so to maintain the tension at a predetermined value. The reel 2 of covering material revolves on a table 1b and is firmly attached to a ring 4 which revolves around a hollow pivot 1a. The ring 4 slidably engages a bush 5 which runs on bearings 6, 6a and can be freely rotated about a sleeve 7 which can be displaced axially on the .pivot 1a by means of a screw thread 7a. The lower part of the bush 5 tapers towards the table 1b to receive a braking cone 8, which is axially movable on the pivot 1a and is loaded by a compression spring 9. The lower edge of the cone 8 is provided with ratchet teeth 8a which engage corresponding teeth 14a on an annulus 14 firmly connected to a double lever 15 carrying a guide roller 16. A second lever 15<SP>1</SP> arranged symmetrically to the lever 15 is mounted on an annulus 14<SP>1</SP> and carries a guide roller 16<SP>1</SP>, the annuli 14, 14<SP>1</SP> being mounted on bearings 12, 13 for pivoting about the axis 1a.

Title: Improvements in or relating to the bonding of particles of foamed material
Inventor: MILLAR RICHARD DAVIES
IPC: C08J9/35
Filed: 1959-10-15
Abstract: A method of bonding particles of foamed material comprises coating them with a mixture of the component materials for a polyether-type polyurethane, pressing together the coated particles and subsequently transforming the component materials into foamed polyurethane by subjecting the coated particles to the action of dry steam.  The particles can be of polyester or polyether urethane, rubber latex foam or sponge rubber.  The component materials for the polyether-type polyurethane can be employed as such or in the form of a prepolymer, suitably together with N-methyl morpholine, silicone oil, dibutyl tin dilaurate, and p-t-butyl catechol.  The dry steam can be applied to the coated particles through holes in the mould in which they are pressed together or by putting the mould into an autoclave through which dry steam is passed under pressure. Specification 898,272 is referred to.ALSO:A method of bonding particles of foamed material comprises coating them with a mixture of the component materials for a polyether-type polyurethane pressing together the coated particles and subsequently transforming the component materials into foamed polyurethane by subjecting the coated particles to the action of dry steam.

Classes 24 and 65(2) In a tool-carrying chain of the type having ball and socket joints between the links, the socket member 12 of each link is provided with a recess 27 bored into it from the opposite face from that into which the ball stem 21 enters, and the recess is fitted with two half-liners 28 which are secured in position by a rivet 33. The half-liners are cut away as indicated at 34 to permit bending of the chain, the cut away portion extending round nearly a quadrant. In an alternative construction the cut away portion extends right across each half-liner so that the half-liners are symmetrical and identical. The pitch can then be restored, when the chain is worn, by reversing the positions of the half-liners in the socket. The ball stems 21 are removably secured in extensions 20 of the tool-carrying bosses 13 by rivets 23, and the extensions 20 are provided with curved abutment surfaces 25 to prevent back-bending of the chain. Each socket member 12 is extended by side walls 15 which carry flanges 16 to run in the guides of a coal-cutter jib, and the space between the side-walls 15 is shaped as indicated at 17 to engage the teeth of a driving sprocket.

Abstract: 509,577. Electrodeposition of zinc. HUBBELL, J. P., and WEISBERG, L. Dec. 1, 1938, No. 35037. Convention date, Dec. 1, 1937. [Class 41] Zinc is deposited by electrolysis from a concentrated ammoniacal zinc solution containing free ammonia at a current density of 500- 1,000 amps. per sq. ft. The electrolyte is prepared from low grade ores, raw zinc ash, or sal skimmings by leaching with ammonia and ammonium salts. Chlorides and small quantities of cadmium and copper may be present. Iron is oxidised by hydrogen peroxide and is then filtered off. The electrolyte contains 80-150 g. per litre of zinc and at least 8g. per litre of free ammonia. Insoluble anodes of gas carbon, graphite, or stainless steel are used and the temperature maintained at about 30C. either by cooling means within the cell or by circulating the electrolyte through cooling pipes. Agitation is effected, either by mechanical means, or by drawing wire to be coated through the bath at a speed of at least 120 ft. per minute, sufficient to cause turbulent flow of the electrolyte. Exhausted electrolyte is regenerated by using it to leach fresh zincbearing material.

Title: Improvements in apparatus for separating dust from air
Inventor: PROVAN JOHN DOUGLAS
IPC: B01D50/00
Filed: 1963-09-06
Abstract: 1, 034, 468. Filtering gases; cyclone separators. PROVENAIR Ltd. April 24, 1964 [Sept. 6, 1963], No. 35361/63. Headings B1T and B2P. Apparatus for filtering dust from gas or air comprises a chamber 1 closed by a top plate 2 and having a tangential gas entry 8. Fabric filter sleeves 20 supported by the plate 2 open into a chamber 4 connected to a gas outlet pipe 9. The air is caused to circulate by a suction fan connected in the pipe 9 or by a pressure fan connected in the entry 8. The heavier dust particles are removed cyclonically due to the tangential entry 8 and are deposited in the hopper 5, the finer particles being deposited on the sleeves 20. The sleeves are cleaned sequentially by a reverse air flow derived from a centrifugal fan 10 mounted on a shaft 11 driven by a motor 13. The fan 10 draws in air from the chamber 4 and expels it through nozzles 18 of a manifold 17 forming the fan casing 15. The casing 15 is mounted on the shaft 11 by bearings 16 and the reaction of the air passing to the nozzles causes the casing to rotate so that cleaning blasts of air are supplied to each one of the sleeves in turn. As shown, the sleeves are arranged on two circles and internally supported by wire cages 22, the cleaning air blasts causing the sleeves to be momentarily expanded and contracted to augment the cleaning effect. In a modification, the casing 15 is not rotated by the reaction of the air passage but by a motor 26 driving the casing through gearing 23, 24. The sides of the hopper 5 are swept by a pair of flexible members 27, e.g. chains, connected to the ends of an arm 28 rotatable on a shaft 29 so as to dislodge accumulated dust. The arm may have vanes 31 whereby it is rotated by the air from the entry 8; alternatively, the arm may be rotated by the motor 13. In another arrangement (not shown) the apparatus is disposed horizontally.

Title: Improvements in the production of fuel
IPC: C09B49/10
Filed: 1934-12-10
Abstract: The separation from coke oven and like gases of a fuel consisting of easily liquefiable gaseous hydrocarbons as claimed in the parent Specification is effected by treatment with active carbon or the like at pressures of 1--10 and preferably 1--5 atmospheres, said pressure being also utilized for other purposes such as supplying the gas through mains to a distance.  When the gas is compressed in stages adsorption may be performed between the stages.  To avoid loss of gas during regeneration of the adsorbent direct steam is only employed for this after several charges, the intermediate regenerations being performed by indirect heating with or without reduction of pressure.
