Patent GB-2276718-A (GB)
Title: Instrument for measuring velocity and direction.
Inventor: BRISCOE JOSIAH ALFRED
IPC: G01S11/12
Filed: 1993-03-31
Abstract: An optical instrument for sensing absolute movement v of the instrument, relative only to the aether in which light propagates, comprises a coherent light source 1, which is a laser beam, divide 2 into two parallel rays which fan out as spherical wavefronts and overlap at an observer position to create optical interference fringes. The lateral positions of the fringes are affected by lateral motion through space at velocity v measured in the plane of the parallel ray axes. Displacement of the fringes is detected by a photoresistor 6 placed behind a pinhole in a screen 5. The screen can also be laterally displaced to scan across the fringes. The instrument can be suspended to allow rotation in order to vary its absolute orientation, which is said to be detectable by the fringe displacement. The instrument thus has navigational or educational applications. <IMAGE>

Title: Pulse actuated clutch with latching for vehicle drive lines
Inventor: BIGLEY JON A
IPC: F16D25/061
Filed: 1994-10-26
Abstract: The pulse actuated clutch, which may be a vehicle hub clutch for engaging four wheel drive, has a coupling member 300 that is permanently engaged with one of a driven member 280 and a driving member 30. The coupling member 300 is movable in a first direction to engage one of the driven and driving members 280, 30 and is movable in a second direction to engage both the driven and driving members 280, 30. The coupling member 300 is biased to move in the first direction by a return spring 310. The coupling member 300 is moved in the second direction by a first pulse of air pressure applied to a piston assembly connected to the coupling member 300. Formations 340, 352 formed on a primary piston 330 of the piston assembly and the driven member 280 cooperatively latch the piston 330 in the second position to maintain the coupling member 300 in engagement with both the driven and driving members 280, 30 upon release of the first pulse of air pressure. Preferably, a second pulse of air pressure greater in magnitude than the first pulse moves the primary piston 330 further in the second direction against a second spring 332, which unlatches the piston 330. <IMAGE>

Patent GB-2305033-A (GB)
Title: Controlling brushless dc motors
Inventor: WERSON MICHAEL JOHN
IPC: H02P6/08
Filed: 1995-08-25
Abstract: In a brushless dc motor controller having electronic switches to control the current flow in each phase of the motor, event sensors such as Hall sensors 100 are used to detect certain positions of the magnet flux of the motor. The switches are turned on or off by outputs from a commutation circuit which decodes the outputs from the event sensors. Operation of these switches can be extended over a greater angular range by turning the switches on earlier and holding them on for longer in order to achieve a greater power output and efficiency from the motor. A Phase Resetting voltage controlled oscillator is used to predict the angle between sensor events and this is compared to a start angle and an on angle which will be set for maximum power output. These comparisons are then used in a gated bistable circuit to generate the switch control signals. A period based phase correction loop (PBPCL) 102 is described in more detail (Fig 7) and controls via a phase advance duration control 108 (Fig 8) a commutation logic 114 (Fig 9) which switches the phases of the motor. The motor is PWM controlled.

Title: Lock mechanism
Inventor: OWEN ANGHARAD ELLIS
IPC: E05B63/14
Filed: 1995-10-06
Abstract: The lock mechanism comprises a housing (10) for fitting to a face of a second member, eg a door, and contains a latch mechanism (20), and a knob (50) for fitting to a first member, eg a frame, which engages with and latches to the latch mechanism (20). The housing (10) comprises a rear face (40) for attachment to a face of the second member, the rear face (40) extending to form an aperture (30) to receive the knob (50).

Title: Driving simulator
Inventor: TOMLINSON JOHN PHILLIP
IPC: G09B9/048
Filed: 1996-01-30
Abstract: A driving simulator comprises a model of a terrain carried on a magnetic plate 24 movably supported on a table top. Nylon spring-loaded ball bearings mounted in, or flow of air through holes in, the table top provide low-friction support for the plate 24. Two wheels 40, 56 extend through apertures in the table to engage the plate. The wheels are magnetisable enabling variation in their frictional engagement with the plate. Wheel 40 is rotatable about an axis normal to the plate and drives the plate in translation at a rate determined by the user. The second wheel 56 acts as a pivot for the plate converting translational motion into rotational motion. The relative positions of the wheels is variable and the second is carried on a beam with a moveable counterweight so that the force biasing it is against the plate is variable. Optical probes coupled to video cameras above the model provide a view of the model surface to a user.

Title: Door or window stay
Inventor: SMITH CLIVE JAMES
IPC: E05D15/30
Filed: 1996-03-28
Abstract: In a friction stay for a door or window comprising a base 10 for connection to a frame and an arm 13 for connection to the leaf with a linkage 14, 16 controlling the movement of the arm relative to the base so that the arm moves in a plane generally parallel to the base between the closed position in which the arm overlies the base and open positions in which the arm is to one side of and angled relative to the base, a reinforcing member 28 is provided extending along the arm 13 with the connection 23 between the shorter link 16 and the arm also engaging the reinforcing member and a fixing hole 27 extending through the arm 13 and the member 28 at a position spaced from the connection. If the arm is forced away from the base during an attempt to force the leaf out of the frame, the strength of the stay to resist such a force is increased by the reinforcing member. Preferably the reinforcing member 28 comprises a metal or plastics plate and the connection 23 comprises a rivet. This arrangement is particularly useful where the arm is to fit into a "eurogroove" on a leaf.
Patent GB-2312783-A (GB)
Title: Opto-electronic device with quantum well structure
Inventor: NELSON ANDREW WILLIAM
IPC: H01S5/042
Filed: 1996-05-01
Abstract: An opto-electronic device, such as a light-emitting diode, comprises a transparent high lateral conductivity current spreading layer 31 overlying a conventional p-n junction active region 10. The current spreading layer 31 comprises a multiple quantum-well heterostructure having a plurality of thin layers 33 of a material having a band-gap narrower than the band-gap of the active region disposed between layers 32 of a material having a band-gap greater than or equal to the band-gap of the active region 10, the wide band-gap layers 32 being more highly doped than said narrow band-gap layers 33. Quantum confinement occurs in the narrow band-gap layers 33, so that it becomes transparent to light emitted from the active region 10. Furthermore, the layers 33 of narrow band-gap material become highly conductive owing to charge carriers which have transferred from the more highly doped wide band-gap material layers 32. The quantum-well heterostructure thus forms a transparent layer 31 which acts to spread current across the entire active region 10.

Abstract: The pump comprises a housing, a cam ring 17 with internal cam surface 17a, and a rotor inside the cam ring having vane 21 retaining support slits S. Pump chambers P1 (P2) are formed by the cam ring, rotor and adjacent vanes. A pair of intake ports 25a (25b Fig. 1) exhaust ports 27a(b) are radially oppositely formed on a side plate (18) for inhaling and discharging fluid from the pump chambers which communicate via notch 33 and communication groove 35 formed on the side plate.
