Title: Sliding door power drive with lock actuator - has chain or rack transmission with door unlocking lever
IPC: E05F15/643
Filed: 1974-06-21
Abstract: A chain or a toothed rack is provided for connecting the sliding door to the motor or to the handle. The sliding door drive is connected to the sprocket wheel of the motor by a chain or a rack pivoted between two pivoted levers so that their movement is restricted. A stop is provided for automatic releasing of the sliding door lock. This stop acts in conjunction with the rotating locking catch and the stop is actuated by the lever on the chain. When the motor is switched on for opening the door the chain is moved relative to the door at first without moving the latter. The lever is rotated and it actuates the catch for releasing the door lock. Further rotation is stopped and the door is now moved by the motor its sprocket and the chain. Hence the door is unlocked before any movement takes place.

Title: Low wear aircraft wheel - with wind blades to rotate wheel prior to touch-down
Inventor: BRUENING CARL H J
IPC: B64C25/40
Filed: 1974-07-31
Abstract: The wheel disc of the aircraft wheel is fitted with a number of specially shaped turbine blades (20). The inclination and spacing of the blades can be adjusted to suit the size and weight of wheel. As the aircraft lands and extends its wheels the slipstream turns the wheels via the blades. A ratchet control ensures that the wheel can only rotate in the forward direction, and brakes the wheels if they try to rotate backward. As the wheels touch the runway they are already rotating and thus do not skid on the tarmac. The system is applicable to all aircraft, but especially to high performance aircraft which usually have a short tyre life.

Patent DE-2443464-A1 (DE)
Title: Pulling mechanism for crystal growing - using two opposed hydraulic cylinders with slight speed difference to produce slow motion
Inventor: FLISIKOWSKI PETER
IPC: C30B15/30
Filed: 1974-09-11
Abstract: Pulling mechanism for drawing single crystals from melts has two counter opposed hydraulic cylinders operating at slightly different velocities to create the very slow speed needed. The first cylinder piston is connected to a linkage which is also connected to the second cylinder. The required motion is then achieved on the piston rod from the second cylinder. The cylinders can have a telescopic construction. The piston from the second cylinder can be mounted in a bearing so that a lower section can have a rotational motion added to it. Of particular use with single crystal manufacture from melts, esp. with additives present. The production of the very slow uniform motion needed for this is difficult with a single cylinder (a) because of the frictional effects in the cylinder causing irregularities and (b) the fluctuations present in the hydraulic signal. However at greater speeds, these effects are much less significant, therefore by using two opposed cylinders operating at higher but different speeds, the required accurate uniform slow motion is achieved.

Title: Opto-electronic safety barrier for dangerous machinery - uses light bundles reflected to emitting lens and receiving conductor
Inventor: OTT ALBERT DIPL ING
IPC: F16P3/14
Filed: 1974-12-14
Abstract: The system protects personnel entering the dangerous areas of machines, and incorporates a number of light beam bundles situated directly one above the other. Each bundle emanates from the end of a rectangular light conductor and is formed by a lens into a virtually parallel bundle. This strikes a prism reflector which reflects it back to the emitting lens, where it is projected by a radiation distributor onto a receiving light conductor on the emitting light conductor. The receiving conductor can, as a result of the time multiplication emission process, only be illuminated during the emission phase and when the path of the beams is unobstructed by any part of a person's body at any point over its entire length.

Title: Fuel supply system and carburettor for IC engine - has series of walls which together form a wave guide between atmosphere and engine
Inventor: BEEKHUIS JUN WILLIAM HOUDYN
IPC: F02M13/02
Filed: 1975-05-12
Abstract: Fuel supply system and carburettor for an I.C. engine is designed to limit exhaust emissions e.g. unburnt hydrocarbons and carbon monoxide and to eliminate a pressure decay in the system. A system of walls from a wave conductor or guide whose one end is open to atmosphere and whose other end is connected to the inlet opening of the engine and is so constructed that it forms a flow channel for the fluid medium. An opening in the wave guide walls open out into the flow channel which operates so that the max. pressure effect formed by a shock wave at the opening is greater than the maximum pressure effect occuring at the opening as occasioned by the speed of the medium in the channel. A wave guide housing acts as a shock wave absorber. The fuel passing into the flow channel in the wave guide is controlled only by the pressure action arising at the opening. Throttle valves are positioned in the wave guide between the fuel inlet into the channel and the inlet to the engine.

Title: Identification of coloured surface - is by electronic circuits simulating primary colour outputs of optical electrical measurement
Inventor: KELLER HANS DR
IPC: H04N1/54
Filed: 1975-10-07
Abstract: An opto-electrical channel is used to probe a coloured surface to produce electrical signal values for the three primary colours. Electronic circuits produce outputs to simulate these values which are then applied to coincidence circuits to indicate the existance of the particular colour. A coloured surface is probed by an opto-electrical channel which produces measured values of the three primary colours (R, B, G). These signals are limited in a colour space diagram by the identification of the colours which are simulated by an electronic system. This system produces reference values which are applied to coincidence circuits and which then indicates the existance of a colour when its coordinates are within the limits bounded by the primary colour coordinates.
