Title: Prepayment water supply systems
Inventor: PATTINSON NEVILLE GRAHAM
IPC: F16K29/00
Filed: 1992-10-08
Abstract: A prepayment water supply system comprises a token, eg a key 10 having a memory and a supply control device 12 incorporating a receptacle 14 for receiving the token and a circuit for reading the contents of the token memory. The circuit controls the water supply by means of an electrically-operated valve 28 in dependence on the contents of the token memory. To prevent the valve becoming stuck in one state if it remains in that state for a prolonged period, eg more than seven days, the circuit periodically produces a pair of signals which respectively change the valve to the other state and almost immediately change it back to the one state. Additionally, such a pair of signals is also produced if water flow is detected when the valve is supposed to be closed. <IMAGE>

Title: I.c. engine optimum starting control system
Inventor: KUWABARA MASARU
IPC: F02D41/34
Filed: 1993-02-03
Abstract: In a multicylinder ic engine 1, an injection pulse length is calculated from engine operating conditions eg cam angle and coolant temperature, and it is then determined whether the engine is in a starting or warm up mode. To improve the ignition properties in the starting mode, the required pulse length is split in two with the half pulses being applied simultaneously to the injectors of the intake and exhaust stroke cylinders. When stable combustion is achieved, the warm up mode is such that the injection pulse finishing time is determined in an engine temperature dependent delay function. The appropriate start time is then set to give the required pulse length. The delay becomes smaller as the engine warms up so that the injection time becomes earlier. <IMAGE>

Title: Resetting the wheels of trailing steering axles
Inventor: ANTON ARNO
IPC: B62D13/04
Filed: 1994-02-15
Abstract: The wheels (6) of each trailing steering axle (3b) are connected by a track rod (7) and are provided with brakes actuatable independently of one another. Resetting of the wheels (6) to the straight steered course from a deflected position is assisted by a brief actuation of the brake of the forwardly deflected wheel, eg by means of cams 16 on the track rod 7 which actuate a respective brake-actuating valve 13. The wheels are thus reset reliably even with high rolling resistance and large contact area between the tyres and the road. <IMAGE>

Title: Attaching print wheels to drive shafts.
Inventor: TIETZ GERHARD
IPC: B41J1/30
Filed: 1994-11-10
Abstract: The hub of a daisy wheel is axially retained on a shaft end by resilient sprags 7 engaging in an annular groove in the shaft end, and is retained for rotation with the shaft by an axially resilient stud 12 which is mounted at the apex of an arc 10 of resilient material (defined between arcuate slots 9 concentric with the hub axis so as to be able to bow from the plane of the hub).

Title: Magnetic field cancelling system
Inventor: SPICER DENIS FRANK
IPC: G01R33/025
Filed: 1995-05-05
Abstract: A magnetic field cancelling system comprises a flux gate, bias coils, flux sensing means 30 and a feedback means. The initial value of magnetic field as registered at the flux gate by the flux sensing means 30 is maintained by measuring subsequent variations in magnetic field and using the feedback means to vary the current in cables 34, 36, 38 and produce a field fluctuation equal and opposite to subsequent fluctuations. The magnetic field cancelling system can be connected to a magnetic field production system 42 to enable an area around equipment 40 to be kept at a constant field value. A reset arrangement couples the feedback means to the bias coils to produce an initial zero field at the sensing means 30. <IMAGE>

Title: Seperating wood fibres from other fibres in fibremat residues
Inventor: CHOW SUEZONE
IPC: B27N1/00
Filed: 1995-08-23
Abstract: Residues from fibremat materials are broken down and separated into wood fibres and other fibres so that the fibres may be recycled. If the fibremat residues are not recycled, they present a disposal problem due to the uncured resins that become toxic waste. The fibremat residues are cut and separated by rotating cutting heads 26 within a cutting and separating chamber 24. The wood fibres, being the heavier fibres, settle out, pass through a screen 32 into a collection chamber 34 and the lighter textile fibres are sucked out of the cutting and separating chamber 24 with a vacuum system 46. Gates are opened and closed to pass the fibres in batches through chamber 24. <IMAGE>

Title: Protecting a work of art
Inventor: STARFORTH ALAN
IPC: A47G1/06
Filed: 1996-06-03
Abstract: To protect a work of art against fire, theft or vandalism, the work is hung in a frame, and when a sensor detects a threat, a canopy is automatically lowered to protect the work. When one of the sensors at 15 detects a threat to wotk of art 14, a motorised reel 12 will automatically wind in belt 6 to pull down exterior canopy 3 and interior canopy 4 via canopy bars. With canopy lowering, protective bars 7, for the external canopy, and 8, for the internal canopy, are raised to a protective position. The canopy bars are then bolted in holder 9, and side clamps move over both canopies to seal off the work of art. The protective bars establish a protective cage. Movable parts are concealed under paper which tears as the canopies move. A non-flammable coolant gas may be released between the canopies. A battery back-up for the power source may be provided.
