Title: Molydenum gate fet - using doped oxides for diffusion and passivation
IPC: H01L21/8238
Filed: 1971-09-30
Abstract: Autoregistered molybdeum gate F. E. T. and complementary transistors using doped oxides for diffusion and passivation. The Mo gate is used to define the source and drain, and gate dielectric. A layer of undoped oxide on top of the doped layer prevents out-diffusion, and since it etches more rapidly gives sloping sides to the contact windows. The technique gives good control of diffusion, complete passivation and buried layer Mo interconnections.

Title: Hollow building blocks used as permanent formwork - can be reinforced and concrete poured into vert. cavities
IPC: E04B2/54
Filed: 1973-04-09
Abstract: The blocks (1) consist of two or more side walls (11, 12) linked by cross walls (13) at regular intervals, forming cavities. The distance separating the edge of the block from the first cross wall is equal to half the distance separating the other walls, thus allowing blocks, when assembled, to have cavities of the same size. The blocks are placed one on top of the other, mortar being placed in between, so that cavities (14) are aligned. Concrete is then poured in and vertical reinforcement bars inserted. It is not necessary to use shuttering and therfore saves both time and money.

Title: Compressed air driven reversible motor - has large central gear with satellite gears in casing chambers
IPC: F01C1/14
Filed: 1974-03-13
Abstract: The motor has a central toothed gear wheel which meshes with a number of satellite wheels which are housed in a casing. Compressed air is admitted to the ports causing the wheels to rotate. The air is then exhausted through the ports. Reversing direction of the flow of air reverses the direction of rotation of the motor. The power output of the motor is proportional to the number of pairs of satellite gears so that a large power can be produced from a compact machine running at a relatively low speed.

Title: Boiler to heat water and generate high pressure steam - has wide range of output control and greatly reduced condensation at low output
IPC: F24H1/40
Filed: 1974-06-20
Abstract: Boiler has a small water tank with inlet at the bottom. Small bore water tubes connect to large water tubes arranged in a circle near the insulated wall round the main combustion area, going upwards to end in a steam collecting drum with a hot water outflow. On top of the boiler is an oil burner, and waste gas exhaust. The top of the large tubes, may have valves. The burner points downwards heating the main combustion area, pre-heating the water tank, and the hot gas is directed upwards through riser tubes, within the large tubes. Heat output can be controlled by shutting down some of the top mounted valves. A variation of the boiler can have the burner at the bottom using solid fuel. Special covering for the combustion area is unnecessary as the water tubes surround it. The outside cover keeps cool, and has low condensation at low output.

Title: Anti-theft alarm circuit for car accessories - has bridge detecting imbalance caused by removal of accessory
IPC: B60R25/10
Filed: 1974-09-04
Abstract: The circuit protects the external electrical accessories of a car by detecting disconnection or removal of the accessory from the vehicle itself. The detection is obtained by the level of the mid-point voltage of a dividing bridge increasing beyond a balance value when an accessory is removed or disconnected. Terminals (A), (B) feed the accessories, with diodes (D1), (D2) giving independent feed to each. A transistor (T) can be used as a non-limiting detector of voltage level. Its emitter is joined to a dividing bridge (R1), (R2) and it becomes a conductor when the voltage at point (D) exceeds that at point (E) by about 0.4 volts. The current flows to a point (C) and sets off the alarm.

Title: Catamaran with adjustable sails - allows mast, rigging and sails to be moved from one hull to other to suit wind
IPC: B63B15/02
Filed: 1975-12-29
Abstract: The sailing boat with a catamaran hull has a single mast which can be moved from one hull to the other, complete with all the rigging and sails.

Title: Pipe couplings with axially compressed annular polyurethane seals - for butt joint seals which can tolerate vibration
IPC: F16L41/00
Filed: 1976-04-26
Abstract: Pipe couplings incorporate annular seals made of flexible polyurethane which can be dilated radially by axial compression between two clamps and a collar to seal against the coupling walls. Suitable for pipe systems for central heating or for conveying gas, compressed air or hydrocarbons. The coupling design does not require the pipe ends to be externally threaded, though a ribbed or grooved pipe end profile can provide enhanced grip. A component mounted between twin couplings may be released and removed without disturbing the adjacent pipes. The couplings can withstand vibration. Embodiments describe couplings for joining pipes of similar or dissimilar diameters. One variation involves an olive interposed between two pipes having flared ends. Saddle type couplings are also described for sealing pipe branch connections normal or oblique to the main pipe. The seal may be trapped in a butt joint between two pipe sockets fitted with internal and external sleeves.
