Patent GB-2144455-A (GB)
Title: Doffer robot for open-end spinning machine
Inventor: SMITH ALAN
IPC: D01H9/10
Filed: 1984-06-13
Abstract: A doffer robot (1) includes a transport conveyor for empty conical winding tubes. The tubes (4) roll along the chute of the conveyor and on leaving the chute pass a reversing portion (4a) where every alternate tube (4) is reversed to arrive at a pre-winding position (4b) where seeding yarn (5) extending between a supply package (6) and the last preceding pre-wound tube (4c) is drawn into position ready for formation of the transfer tail. The pre-wound tube is then substituted for the full package doffed by the robot. <IMAGE>
Patent GB-2160848-A (GB)
Title: Carton
Inventor: COOKSON GEOFFREY ROGER
IPC: B65D5/10
Filed: 1984-06-28
Abstract: A carton, especially suitable for use in a coil package, is formed from a folded cardboard blank and has a pair of oppositely disposed side walls, oppositely disposed side edges of these side walls each having an integral flap, one of which overlies and can be secured to the other. The first flap has a slot inclined at an acute angle to this side edge and the second flap has a line of perforations which, when the second flap overlies the other, overlies the slot in the other flap. When it is desired to reclose the carton temporarily, the second flap is folded along the line of perforations to form an ear of such a shape that, when the second flap is folded to overlie the first flap, the ear engages in the slot in the first flap and resists separation of the flaps. <IMAGE>
Patent GB-2144890-A (GB)
Title: Computer reset arrangement
Inventor: FREEMAN JOSEPH WAYNE
IPC: G06F1/00
Filed: 1984-07-03
Abstract: Cartridges for a microcomputer have two adjacent edge connectors replaced by a single connector (14) with a projection (29) which passes into the area in which the adjacent connector would normaliy be placed. When the cartridge is inserted or removed from the connector socket (3) in the microcomputer, the projection transiently shorts a pair associated socket contacts (27,28). A fixed potential (for example earth potential) normally applied to the main portion of the edge connector from its associated contact (28) of the pair is therefore transferred to the transiently contacted contact (27) to provide a reset signal for the microprocessor of the microcomputer. Thus, the microprocessor is reset each time a cartridge is inserted or withdrawn.
Patent GB-2152465-A (GB)
Title: Apparatus for stacking and banding tags
Inventor: GOLICZ ROMAN NICOLAS
IPC: B65B25/14
Filed: 1985-01-04
Abstract: Apparatus for banding tags (T) into stacks S comprises an endless belt conveyor (17, Figure 1) for moving tags transversely to a stacking position where they are stacked. A pair of webs W,W' of heat sealable material are fed to either side of the stack and are heat sealed together by jaws 36,37. The fixed jaw 36 has heat sealing elements 43,44 for making spaced seals and a selectively operated severing element 46 operable to separate any banded stack or series of stacks from an adjacent stack. The movable jaw 37 has a perforating knife 40 which is opposed to a cushion 42 to provide weakening lines between adjacent banded stacks to facilitate ready separation thereof. The stack is moved between the jaws, and the jaws are brought together first below and then above the stack. The movement of the stack and the jaws is powered by a continuously operating motor (50) (see Figure 8) which is coupled to the stack transfer slide 33,34 and to the movable jaw by respective single-revolution clutches (67,68) each controlled by an electromagnetic solenoid (84,90). The clutch (68) is coupled to the movable jaw (37) by 2:1 reduction gearing (74,74') a connecting rod (86) and bell crank (88), and the other clutch (67) is similarly coupled to the transfer slide. <IMAGE>

Title: Light fitting
Inventor: HALL STEPHEN MARK
IPC: F21V17/16
Filed: 1985-04-04
Abstract: The lamp holder 12, 14 of an adjustable light fitting is carried on pivot studs 11 which in turn are carried in a conical shield 4 which can rotate about its axis. The lamp holder includes a bracket 12 and a cylindrical cowl 15 for the lamp 1 has integral, snap projections 17 which engage over the rear end of the bracket 12, enabling the cowl 15 to be slipped on and off without difficulty. The axis of the pivot studs 11 is in the plane of the extreme ends of an opening in the shield 4 through which the cowl 15 passes; in this way, the gaps around the cowl 15 appear to be of minimum size. To restrain the bracket 12 against free pivoting movement, there is a sprung hoop 21 which engages the rear end of the bracket 12 and is slightly smaller radius than that required so that it is distorted outwards, thereby applying a frictional restraint to the bracket 12 in a very simple manner. <IMAGE>

Title: Duplex filter
Inventor: WHYTE JON FRANK ROSS
IPC: B01D29/11
Filed: 1987-01-14
Abstract: Two filters 1, 2 are connected in parallel, and only filter 1 is provided with a movable backflushing nozzle 12. Valve 5 normally directs flow through filter 1, until rising pressure necessitates switching the flow through filter 2 while filter 1 is backwashed. Thereafter flow is restored through filter 1. The element 14 in filter 2 is periodically replaced when dirty. In Fig. 1 the flow switching is automatically controlled by pressure drop monitor 17, and the backwashing of element 13 is effected by nozzle 12 which rotates as it is advanced axially inside element 13 (Fig. 2, not shown) by a piston 22 for a period determined by restrictor 37. In Figs. 3, 4 the switch over and nozzle movement are effected manually.   <IMAGE>

Title: Method of forming an article including a ceramic superconductor
Inventor: HEPBURN WILLIAM DUNN
IPC: H01L39/14
Filed: 1988-02-23
Abstract: A method of forming a surface layer of a ceramic superconductor, of the perovskite type, comprises providing a body of an alloy of a non-oxidising, electrical conductor, such as gold, together with appropriate amounts of the metallic elemental constituents of the superconductor, e.g. Y, Ba and Cu, heating to cause the metallic elements to diffuse to the body surface and during diffusion oxidising the surface. The oxides formed during oxidation become mixed at the surface to form the superconductor layer on the remaining part of the body, which supports the superconductor layer, and prevents relatively hot regions occurring within the superconductor when the superconductor is magnetised excessively. The body may be a refractory wire e.g., Mo or hollow tube coated internally and externally with ceramic superconductor. Coolant may flow through the tube.
