Patent GB-2168149-A (GB)
Title: Level sensing device
Inventor: WILSON RONALD
IPC: G01C9/10
Filed: 1985-11-21
Abstract: A level sensing device consisting of a metal ball (16) which is free to gravitate within a circular aperture (12) formed in a metal plate (11), the plate (11) being divided to form two halves on a diameter of the aperture thereby to constitute switch contacts closeable by the ball (16). The plate (11) and ball (16) are located within a plastics housing (10) for retaining the m ball (16) within the aperture (12) there being clearance between the ball (16) and the housing (10) sufficient to allow free movement of the ball (16), An audible indicator (18) and or visual indicator (19) may be connected to the two halves of the plate (11) by conductors (14, 15). <IMAGE>

Title: Wheel for a toy vehicle
Inventor: ROSENWINKEL DONALD ALFRED
IPC: A63H31/00
Filed: 1986-01-23
Abstract: A toy vehicle wheel that changes from a generally cylindrical periphery with an initial diameter and axial width to a greater diameter periphery. The wheel has a hollow shell of rubber or some other flexible material and opposed sidewalls of the wheel are moveable relative to each other to compress the axial width and increase the diameter. Across a substantial portion of the initial axial width a number of slits extend so that the periphery is serrated when it is enlarged. In one form, an axial screw engages a sidewall to rotate the wheel in its initial quiescent condition along a relatively unobstructed surface, but, upon encountering an obstruction, will draw the one sidewall toward the other. Variations provide for containing the axial screw within the compressed wheel or permitting it to extend out of a sidewall. Other forms provide for movement of the sidewalls relative to each other with bayonet locking in a desired condition and for spring bias in one direction.

Title: Process for the production of a lightweight mirror blank
Inventor: SAUERWEIN PAUL
IPC: C03B19/09
Filed: 1986-03-20
Abstract: For the production of a lightweight reflector blank, graphite forming elements (2) are placed at regular intervals from each other on a silica carrier (1) acting as a reflector or back plate, and the carrier (1) is surrounded with a graphite frame (3) up to the height of the graphite forming elements (2); the gaps (4,5) present between the graphite forming elements (2) and between the graphite forming elements and the graphite frame (3) are then filled with granular silica to form a honeycomb-like supporting framework inseparably joined to the carrier (1) and heated in a vacuum furnace to a temperature of approximately 1730 DEG C. After cooling, the graphite forming elements (2) and the graphite frame (3) are removed; the reflector or back plate specified as the second plate is then affixed on the supporting framework thus obtained.

Patent GB-2208004-A (GB)
Title: A signal propagation technique for distance measurement
Inventor: OWEN MICHAEL
IPC: G01S15/74
Filed: 1987-08-12
Abstract: Distance is calculated by measuring at 7 the time or phase displacement between a reference signal (1) and the same signal returning (6), following propagation between the specified points. The technique prevents interference occurring between the outgoing and returning signal propagated into the mediums, even during the same time frames by changing the signal received at the remote point (eg, infra red) prior to returning it, (as an ultra-sonic signal), to the origin. This allows the possibility of continuous operation of both the transmitted and received signals, and simplifies the requirements for detection circuitry. The propagation medium for sound is required for at least one of the signal forms to facilitate measurable delays by simple electronic circuitry. <IMAGE>

Title: A four-wheel drive vehicle transmission
Inventor: HOLME H R
IPC: B60K17/346
Filed: 1989-06-30
Abstract: The transmission comprises an epicyclic transmission (20) which receives drive from a change-speed transmission (13). The epicyclic transmission provides drive outputs from annulus and sun gears (22, 23) which drive respective final drive units (26, 30) for the front and rear wheels (27, 32). The final drive units provide different ratios and the outputs from the epicyclic transmission rotate at different speeds to provide the correct rotational speeds for the wheels. A manual selector (34) thus permits either four-wheel drive (full-line positions) or two-wheel drive (broken-line positions) at different overall drive ratios to suit different conditions, eg on/off highway. The invention enables a four-wheel drive vehicle to be provided with minimum redesign, using standard components. <IMAGE>
