Patent GB-2358236-A (GB)
Title: Solenoid-operated valve with magnetic latching
Inventor: RHEINER HANS-UDO
IPC: F16K31/08
Filed: 2000-12-11
Abstract: A valve actuator has switching pin 20, cylindrical coil 18 and permanent magnet 22. When electrical current is supplied to coil 18, from safe power supply 13, in a first direction pin 20 is moved towards the permanent magnet 22 and actuates the valve 11. When the current is switched off, the force of magnet 22 on pin 20 is strong enough to keep pin 20 in position and so keep valve 11 open. When current is applied to the coil 18 in the reverse direction, the magnetic force on the pin 20 from coil 18 is greater than that of attraction to magnet 22 and so aided by a spring or fluid pressure, the pin 20 moves to the original position, closing valve 11. Permanent magnet 22 may be positioned either surrounded by or lie outside the coil 18. Switchable energy store for use when power supply fails may be provided.

Title: Coupling for a work machine to allow lateral rotation
Inventor: TROWBRIDGE GREG DOUGLAS
IPC: E02F3/36
Filed: 2001-01-25
Abstract: A coupling e.g. to attach an implement to a work machine comprises a first part (2, fig. 1) adapted to fit the work machine, a second part (3, fig. 1) adapted to fit the implement and which can rotate relative to one another about a shaft 14. Fluid operated locking means 13 are provided so that the two parts may rotate relative to each other or may be locked to prevent rotation. The locking may be achieved by deforming the locking means so that frictional resistance is applied to the shaft. Preferably, a bearing sleeve 13 is deformed by hydraulic pressure in a chamber 16 against the shaft to frictionally hold the moving parts in position. The arrangement preferably forms part of a quick coupler for an excavator.

Title: Microphone adaptor for a respirator
Inventor: DAVIES JOHN
IPC: A62B18/08
Filed: 2001-01-29
Abstract: The invention deals with the problem that, when the user of a radio headset having a boom microphone wears a respirator, he can no longer effectively use the microphone. The invention solves the problem by the simple expedient of a sound tube (14B) which leads from a first end (14a) located at a position where speech can be received from the respirator, to a second end (14c) which makes a push fit over the boom enabling clear speech to be received by the microphone (15). Advantageously the sound tube has a microphone box (14c) for receiving the end of the boom and for directing the sound inwardly through a lateral hole in the boom to a microphone sensor inside.

Title: Semiconductor laser diodes
Inventor: WANG WANG NANG
IPC: H01S5/042
Filed: 2001-10-15
Abstract: Semiconductor laser diodes are described, having triangular or truncated triangular cavities in the form of mesas 3 for the lateral confinement of radiation, based on III-V or II-VI semiconductor compounds. Spatially distributed current injection is used for selective excitation of the chosen optical modes within the cavities. The current injection system comprises a single lower electrode 1 and a multi-contact upper electrode 4, where contact spots (see figs 1-5) coincide with maxima of intensity for optical modes of the cavity which are chosen for selective pumping. Lasers having triangular cavities with distributed injection (TDI diodes) allow a single mode, or controlled multi-mode laser output, with high quality factor suitable for such applications as CD and DVD pick-up heads, laser printers and telecommunications. To lower the threshold current and increase laser power, optically connected arrays of triangular cavities are described (figs. 3-5). A TDI matrix suitable for laser gyroscope applications is described (fig. 5).

Title: Air suspension for vehicles
Inventor: DIXON ALAN GEOFFREY
IPC: B60G17/005
Filed: 2001-12-14
Abstract: An air suspension unit for a road/rail trailer comprises a road wheel axle (10) which mounts to a chassis or frame of the trailer for movement by air-operated means (52;17,21) between lowered operative and raised stowed positions of the road wheel or wheels carried by the axle, and axle retention means (22) for retaining the axle in the stowed position for rail travel of the trailer. The retaining means comprises jaws (24) which are normally mechanically urged, e.g. by spring loading, to a closed position in which they engage around the axle (10) in its stowed position to retain the axle in that position, and are opened by an air operated piston (35) to release the axle. The piston connects to the air supply of the trailer to which the unit is applied for use. Therefore, when the trailer is supported on bogies for rail travel with the axle held in the stowed position by the jaws (24) and the trailer is separated from is tractor so that the air supply is disconnected, the piston (35) is automatically inoperative and cannot open the jaws to release the axle from the stowed position.

Title: Card printing devices
Inventor: DAWSON CHRIS
IPC: B65H1/04
Filed: 2002-10-09
Abstract: Card printing apparatus for printing pass cards and the like generally comes with a relatively restricted size card input hopper. The number of cards that can be processed in a single operation is accordingly limited. The capacity for a single run of card printing can be materially increased without leading to card feed problems because of the increased pressure at the bottom of a stack of cards by arranging that at least part of the in-feed hopper 3 is inclined away from the vertical. In order to maintain the footprint of the printer relatively small, the hopper preferably has two vertical sections 5,6 and an intermediate inclined section. 7.

Title: Future event detection
Inventor: GRANT ROBERT B
IPC: G01D3/08
Filed: 2003-03-05
Abstract: A method for predicting a future event in a parameter X monitored by a sensor comprises; sampling the output x of the sensor at regular time intervals t, performing a mathematical function y = f(x,t), where the rate of change of y with respect to t is greater than the rate of change of x with respect to t, if y falls outside a defined range bounded by a predetermined value Yalarm, incrementing an event counter, and d. when the event counter reaches a predefined warning limit, setting a warning condition warning of the future event. The method is conveniently embodied in a computer algorithm used to operate a warning alarm system providing advance warning of the predicted future event. The algorithm rapidly extracts response data whilst using sensors with relatively slow response and where detection limits are close to the sensitivity, noise or drift of the sensor.

Title: Iterative frequency domain equalizer for a MIMO system receiver
Inventor: NIX ANDREW ROBERT
IPC: H04L1/00
Filed: 2003-03-24
Abstract: An iterative frequency domain equalizer 28 for a Multiple Input Multiple Output (MIMO) system receiver uses an estimated initial solution and then makes a semi-hard decision 34 based on the knowledge that there is a finite possible date set. A regularization method, e.g. the Tikhonov Regularization algorithm, is then used to form an updated soft estimate. The process is repeated until a stoppage criterion is met. The initial soft estimates may be determined using a Minimum Mean Square Error (MMSE) detection process. The equaliser may be used for OFDM or SC-FDE (Single Channel Frequency Domain Equalization) signals. In a second embodiment, once a predetermined number of iterations has been reached the outputs are sent to a channel decoder (70, Fig. 3) instead of directly to the semi-hard decision blocks.
