Title: Manufacture of elongate members such as strand and rope
Inventor: WALTON JOHN MAWSON
IPC: D07B1/06
Filed: 1985-03-19
Abstract: Individual elongate elements (e.g. wires or strands) are drawn off stationary coils in such a manner that the element is elastically twisted. The elements are guided to a stationary closing means in which a bundle of the elements is formed, the elements immediately before being formed into the bundle being substantially free from any curvature that will result in residual slackness in the elongate member being manufactured. The bundle is withdrawn from the closing means and is simultaneously rotated about its axis so as to form the elongate member (e.g. strand or rope) and substantially untwist the elongate elements. The product can be at least 300 m long.

Title: Displacement measuring apparatus
Inventor: RYAN PAUL THOMAS
IPC: G06F3/033
Filed: 1985-11-28
Abstract: PCT No. PCT/US86/02557 Sec. 371 Date Jan. 9, 1991 Sec. 102(e) Date Jan. 9, 1991 PCT Filed Nov. 26, 1986 PCT Pub. No. WO87/03361 PCT Pub. Date Jun. 4, 1987.A tape rule or other displacement measuring apparatus comprises a reader means and a member that are relatively movable. The member carries a position track defined by a sequence of alternative markings made in succession along the member. The alternative markings record different values in a pseudo-random sequence which is the result of repetitive operations on a seed consisting of a small number of elements. The sequence has the property that a group of successive markings of length at least equal to that of the seed occurs at a single position in the sequence so that a succession of markings read from the track and of length at least equal to the seed defines an absolute position of the reading means and the member. The reading means has at least three sensors arranged to respond to different locations within each marking with the pattern of the markings and the location of the sensors arranged so that only a single sensor changes state each time that the member moves through an interval of displacement relatively to the sensing means. The states occur consecutively in alternative sequences along the member that are recognizable by decoding logic fed with successive states as a logical value corresponding to one of the alternative markings depending upon which sequence has been followed.

Title: Tile jig
Inventor: TURNER JEFFREY GORDON
IPC: B28D1/22
Filed: 1986-01-06
Abstract: A tile jig for measurement and cutting of tiles has a flat link 1 pivotally mounted on which is a flat bar 3 having a tile cutting guide edge 5. Also mounted on the link 1 is a flat bar 7 which is longitudinally displaceable along the link 1 by a slot 2/bolt 8 connection. The bar 7 has lugs 12, 13 for abutment with a tile edge while the tile can be cut along the edge 5. The jig is pre-set for tile cutting by location and adjustment of the edge 5 and lugs 12, 13 within a recess into which a cut tile is to befitted so that the thickness of the lugs provide a tolerance for grouting material around the tile when cut and fitted in the recess. The lugs 12, 13, may be interchangeable with other lugs of different thickness. The pivot 4 may include friction pads to restrain unintentional movement of the bar 3. The bars 3 and 7 may have friction pads to prevent slippage on the surface of a tile during cutting. <IMAGE>
Patent GB-2170946-A (GB)
Title: Cell corrosion reduction
Inventor: CHALILPOYIL PURUSH
IPC: H01M6/04
Filed: 1986-02-12
Abstract: Gassing is significantly reduced in electrochemical cells having anodes of metals, such as zinc, by reducing the number of grains in the particles of the polycrystalline metal to at least a third of the original number of grains and thereafter using the metal in the formation of the cell anode. Such grain number reduction is effected by heat treatment of the anode metal at a temperature below that of the melting point of the metal. Corrosion is further reduced with such reduced grain number particles and particularly with single crystal particles by the addition of small amounts of a gas inhibiting surfactant, for example, an organic phosphate inhibitor such as RA600 from GAF Corp. to the cell. Alternatively, or in addition, corrosion is reduced by prealloying the metal particles with small amounts of one or more of indium, thallium, gallium, bismuth, cadmium, tin and lead prior to reduction of the number of grains or the formation of the single crystal particles. A synergistically lowered rate of corrosion and cell gassing is obtained even with reduction of mercury content.
Patent GB-2176851-A (GB)
Title: Liquid supply pump
Inventor: O'HARA JOHN G
IPC: F04B53/12
Filed: 1986-05-15
Abstract: The pump is designed to pump such liquids as isocyanate which must be kept out of contact with the atmosphere. Piston rod 16,18 driven by for example a reciprocating air-motor operates pistons 45,35 in inner and outer cylinders 32,30 respectively. Fluid drawn into chamber 28 past valve 25 on the upstroke is forced on the downstroke past valve 41/42 and through perforations, not shown, into chamber 23a and through perforations in member 34 to chamber 23b to exit 14. Fluid which leaks past seal 49 on piston 45 gradually accumulates in the upper part of inner cylinder 32 until it fills channel 59 and returns to the reservoir via channel 61 between outer cylinder 30 and casing 13. Fluid can also pass seal 57 around the piston rod 16; this gathers in leakage chamber 55 which is drained by pipe 58. Chamber 40 in neck 66 is longer than the pump stroke so that no leakage is carried to seal 64. <IMAGE>
