Patent GB-2248465-A (GB)
Title: Valve control apparatus.
Inventor: EDWARDS JEFFREY CHARLES
IPC: E21B23/00
Filed: 1991-09-30
Abstract: The present invention provides a novel valve arrangement that enables the opening and closing of the test string circulation valve, and - when the valve is closed - the opening and closing of the tubing isolating valve, as many times as desired. To attain this end a number of arrangement are employed: 1) the use of a J-slot indexer to control the operation of a tool, the slot being in the form of two closed loop tracks (one laying within the other, with a common part), the two tracks controlling two different tool mode operations; 2) the operation of a multimode tool by a succession of annulus pressure pulses, wherein an initial operation is effected by pressure changes of a first pulse, and the operation following the subsequent pressure change is effected slowly so that, if a second pulse occurs within a given time (from the preceding pulse), the mode of the tool is altered and a third pulse thereafter causes a different operation to be initiated; 3) the use of two separate J-slot indexers, each in the form of a closed loop track, to control tool operation, one J-slot indexer controlling the movement of a first operating member connected to and driving a second operating member the movement of which is controlled by the other J-slot indexer.

Title: Route selector for sheet like article
Inventor: YAMASHITA MIYUKI
IPC: G03G15/00
Filed: 1992-02-25
Abstract: A route selector for a sheet like article 45 fed along path 24 includes a pair of rollers 22, 23 arranged so that a plane 34 containing their axes of rotation is inclined with respect to a plane 35 which is perpendicular to the sheet feeding direction in path 24.

Title: A plug-in pipe coupling with locking fingers and safety sleeve
Inventor: HOHMANN RALF
IPC: F16L37/133
Filed: 1993-01-04
Abstract: A plug-in coupling for connecting a fluid conduit to a pipe (10) has a coupling piece (1), one end of which is connectable to the fluid conduit, and the other end of which can be plugged into the pipe (10) and connected thereto by resilient locking arms (3) which are able to engage with a radial locking surface (12) of the pipe. A safety sleeve (4) is movable from a release position in which it permits spreading of the locking arms (3) to a securing position in which it opposes spreading of the locking arms (3). In order to be free to choose the material of the safety sleeve, to be able to give the safety sleeve a simple shape, and to permit displacement thereof into the securing position with a small amount of force, but nonetheless to ensure that a high degree of security is given to prevent accidental release, the safety sleeve (4) is held in the release position by a securing clamp (5) which clamps the coupling piece (1) between its limbs (20, 21) and which is releasable by spreading of the limbs (20, 21), in order to permit the safety sleeve (4) to move to the securing position. <IMAGE>

Title: Conveyor system having electrically propelled railcars.
Inventor: SAKAGAMI TATSUYA
IPC: B61C13/04
Filed: 1993-12-07
Abstract: A conveyor system includes conveyor railcars 1 propelled along a rail 2 by brakeless electric motors 8. Each railcar 1 is provided with first and second switches 19, 20 for cutting off the power to the motor 8. A railcar stopping device, placed alongside the rail 2, can be swung into a position in which it engages the first switch 19 as the railcar 1 passes to cut off the power to the motor 8. The railcar 1 then proceeds under its own momentum until a stop 22 provided on the railcar 1 engages a part of the stopping device. The stopping device can be swung out of engagement with the first switch 19 to allow the railcar 1 to proceed. The second switch 20 is activated when it engages a trailing arm 23 of a preceding railcar 1. This occurs before the two railcars 1 collide. <IMAGE>

Title: Mop bucket with pedestal platform
Inventor: MCKAY PETER
IPC: A47L13/58
Filed: 1995-09-01
Abstract: A mop bucket is constructed with a pedestal platform 12 to support a twist action self-wringing type mop, or other mopping means during the compressing squeeze of the wring. When made of plastic by injection moulding it can be made in one piece (except for the handle), instead of two sections for a conventional mop bucket, and can be stacked one inside another for convenient storage and transportation after manufacture. The pedestal 12 is constructed so that the drainage grooves 14 at the top of the pedestal are just above the water level when the mop bucket is in use. By increasing the diameter of the pedestal 12 and making the top platform dished or conical in shape and increasing the depth of the drainage grooves 14 a mop bucket for use with a conventional soft headed mop could be constructed.

Title: Improvements in rigs for wind propelled vehicles
Inventor: GUTHRIE DUNCAN
IPC: B63H9/06
Filed: 1995-11-21
Abstract: A rig 6 for a wind propelled vehicle, such as a sailing boat, comprises an aerofoil 8 and linkage means, for example arms 10 and 12, for connecting the aerofoil to the boat and transmitting force from the aerofoil 8 to the boat. The aerofoil 8 is held in an inclined position such that a net force acting upon the aerofoil has a lateral component (for propelling the boat) and an upward vertical component. The vertical component enables the hull of the boat to plane. Furthermore the linkage means holds the aerofoil 8 to the leeward side of the boat so that the upward force reduces or eliminates any rolling moment exerted on the boat by the aerofoil 8. There is also disclosed a method of achieving forward propulsion of a boat, by positioning an aerofoil 8 at an inclined elevated position relative to the boat, so that the net force acting on the aerofoil as a result of the interaction of the wind therewith acts along a line which passes through or near the effective centre of pressure of any balancing fin means 2 on the underside of the hull 1 so as to reduce or eliminate rolling movement of the hull 1 caused by the net wind force acting on the aerofoil 8.

IPC: B29C65/34
Filed: 1996-08-27
Abstract: In a method of fusion welding resin articles which are difficult to melt due to a fusion retarding element or structure in the composition, a fusion accelerator is applied to the surfaces to be bonded, the accelerator being capable of destroying the fusion retarder when heated. After or simultaneously with this step, the resin articles are heated so that the accelerator destroys the retarder and the surface portions melt and bond before the articles are allowed to cool. The accelerator may be coated directly onto the surfaces to be bonded, or may be applied to an element which is set within the joint, for example on the insulating sheath 4 of a heating wire 3 which is to provide the heat for welding.
