Title: Improvements in devices for forming golf tees
IPC: A63B57/00
Filed: 1925-09-29
Abstract: 247,114. Deike, U. C., and Hyde, C. W. Sept. 29, 1925. Tee moulds. - In a device for forming sand golf tees, and of the kind comprising a mould provided with a handle, the handle is provided with spring means which may be rapped upon the ground to dislodge the contents of the mould. In the form shown in Fig. 3, the mould 10 and handle 11 are stamped from a single piece of sheet metal. A spring tongue 14 projects from the handle and a drain opening 13 is provided in the mould. The handle is hooked to afford convenient means of attachment to the player's pocket or belt. In using the device the mould is filled with sand and may be dipped into water which is allowed to drain off at the opening 13. The tee is dislodged from the mould, in a position for play, by striking the spring tongue 14 lightly against the ground. Additional drain openings 13 may be provided or the mould may be formed of some foraminous material. In a modification, Fig. 4, the spring extremity 16 of the handle takes the place of the spring tongue, and the handle is attached to a glass mould by means of an annular groove 15.

Abstract: 1,188,751. Polymer/wood products. DEUTSCHE GOLD-UND SILBER-SCHEIDEANSTALT. 22 May, 1968 [20 June, 1967], No. 24341/68. Heading C3P. A wood/plastic combination is prepared by a process comprising impregnating wood with a liquid consisting essentially of a liquid, polymerizable ethylenically unsaturated organic compound or a mixture of such compounds, optionally containing a dissolved polymer therein and, if desired, a dissolved plasticizer, and/or polymerization accelerator and/or initiator and/or hardener under sub-atmospheric pressure, followed by hardening, wherein after impregnation, the surface of the impregnated wood is treated with an aqueous or alcoholic or aqueous-alcoholic solution of a film former known per se which contains hydrophilic groups and is insoluble in the liquid, polymerizable organic compound and which solution may optionally contain a wetting agent. Specified film formers are waterglass, cellulose, polyamides and polyvinyl alcohol. In Example 1, copper beech is impregnated with methyl methacrylate containing hydroquinone, lauroyl peroxide and diacetyl peroxide, treated with an aqueous ethanolic solution of polyvinyl alcohol and hardened. Example 2 is similar, except that the film former solution comprises a polyamide and isobutanol. In Examples 3 and 4, the wood is treated similarly, except that methyl methacrylate prepolymer is present in the impregnating liquid and the film forming solution comprises water, soda water glass, KOM and a wetting agent, or an aqueous solution of methyl cellulose. Poplar and copper beech are treated in Example 5 with the methyl methacrylate solution of Example 3 and the film forming solution of Example 1.

Abstract: 1,220,345. Heat setting polyolefin filaments and tapes. COURTAULDS Ltd. 24 May, 1968 [25 May, 1967], No. 24395/67. Heading B5B. Oriented polyolefin filaments and longitudinally oriented polyolefin tapes are heat set by passing the filaments or tapes under tension through and in contact with a fluidized bed of particles heated to a temperature above the melting point of the polyolefin, the duration of the contact and the temperature being selected to induce in the material a residual shrinkage of at most 2À5%, and preferably in the range of 1À5 to 2%, at 140‹ C. The polyolefin may be stereoregular polypropylene and the maximum temperature of the particles in this case may be 210‹ C. The duration of the contact may be from 1 to 30 seconds. In the case of stereoregular polypropylene filaments or tapes the temperature of the particles may be 170‹ to 185‹ C and the duration of contact may be 1¢ to 3 seconds. In the case of polypropylene filaments or tape the filaments or tape may be allowed to shrink by from 1 to 7% in contact with the fluidized particles. Further, the filaments &c. may be stretched as they enter the heat-setting zone by an amount up to 4%, followed by shrinking them in the heat setting zone by an amount which recovers the applied stretch and a further 2 to 3%.

Abstract: 1522424 Reducing catalysts HITACHI SHIPBUILDING & ENG CO Ltd 14 June 1976 [30 June 1975] 24567/76 Heading C7X A denitrating catalyst is produced by coating a metallic surface with Al, such that the Al diffuses partly into the surface, and dissolving the Al by immersion in an aqueous solution of an acid or alkali, preferably of HCI, HNO 3 ; acetic acid, formic acid or NaOH, whereupon the surface may be further activated with a gas containing H 2 SO 3  gas. The substrate is preferably of pure Fe, stainless steel or Ni-base alloy. The substrate is coated with Al by hot dipping, cementation, vacuum deposition or spraying and optionally heated such that a structure is obtained consisting of the substrate, D; Al coating, A; a layer of substrate material diffused into Al, B; and a layer of Al diffused into the substrate, C. The layer C is preferably 30-100Á thick. The subsequent acid or alkali treatment removes layer A and the Al from layers B and C (although some Al may remain in layer C) to give a porous surface, the substrate material comprising the remains of layer B being preferably removed, e.g. by scraping.

Abstract: 1,174,170. Elastic-fluid turbine cooling. GENERAL ELECTRIC CO. May 26, 1967 [June 30, 1966], No.24571/67. Headings F1G and F1T. A cooling arrangement in a double flow steam or gas turbine comprises holes 13 in the first stage rotor wheel 2 and scoops 12 to pump working fluid from the downstream side of the wheel 2 through the holes into the annular space 11. A stationary recirculation conduit 14 connects the space 11 with the working fluid path downstream of the wheel 2. The blades 3 are shaped to have negative reaction adjacent their roots and thus the working fluid in the root region is at a slightly higher pressure on the downstream side of the wheel 2 than on the upstream side. The pressure in space 11 is therefore normally higher than in region 15 causing fluid to flow past the labyrinth seal 9 from the space to cool the seal and wheel face. Flow through the conduit 14 helps to maintain pressure in the space 11, the direction of flow depending upon the condition of the seals 9. The seal teeth 19 are inclined to permit greater flow in the direction of inclination than in the opposite direction.

Abstract: 1,028,638. Friction clutches; variable-ratio gearing. V. WASSILIEFF. June 21, 1963 [June 22, 1962], No. 24823/63. Headings F2C and F2D. A friction clutch comprises a band or coil which is expanded or contracted into frictional engagement with a driving member by control means which simultaneously engages both its ends and is mounted on the driven member. The Figure shows a double-clutch arrangement used in a constant-mesh gear, the clutches comprising bushes 4, 23 having oppositely diverging ends co-operating with rollers 15, 16 and 24, 25 mounted in grooves in a driven shaft 3 so as to be fast axially therewith. Axial movement of the driven shaft 3 in one direction expands the bush 4 into frictional engagement with a driving drum 2 for direct drive, and movement in the opposite direction releases that clutch and expands the bush 23 into engagement with a driving drum 21 to give drive through the constantly meshing gears 17-20. In an intermediate position both clutches are disengaged to give neutral.
