Patent DE-3839963-A1 (DE)
Title: Displacement/angle sensor
Inventor: HANKEL RAINER DIPL ING
IPC: G01C7/04
Filed: 1988-11-26
Abstract: Displacement (position)/angle sensor having two mutually laterally rotated optical sensors and spatial frequency filters (10, 12) which are constructed as diode arrays. A lens (14) and thereabove a telecentric diaphragm as a cross slit diaphragm (16) having slits (18, 20) aligned perpendicular to one another are inserted into the beam path of the diode arrays. A deflecting mirror (22) is arranged above one of the slits (18), with the result that one diode array (10) is arranged in the reflected beam path of one slit (18) and the other diode array (12) is arranged in the transmitted beam path of the other slit (20). Owing to the cross slit diaphragm (16), a virtually lossless distribution of the beam path between the two diode arrays is achieved, with the result that either the diaphragm opening of the cross slit diaphragm (16) can be reduced for the purpose of improving the imaging, or the measuring arrangement operates with an adequate signal-to-noise ratio even in the case of road pavements (28) of low reflectivity. <IMAGE>

Patent DE-3918955-A1 (DE)
Title: Technical simulation of the biological muscle principle as a technical muscle. Robot resembling an animal or a human being and having technical muscles. Parts of this robot as prostheses. Further applications of the muscle: as lifting and tensioning device, as muscle motor, for positioning of an object by several muscles, as adjustment means for the range of spring
IPC: G09B23/00
Filed: 1989-06-09
Abstract: The technical muscles are a simulation of human and animal muscles. They are designed as network muscles and formed by a flexible container and a net which is not stretchable lengthwise. The container can be filled with a liquid or a gas. As a result it expands and shortens the longitudinal extension of the net. This force is utilised technically. The tubular muscle or multiple (multi)tube muscle is designed as a thin-walled elongate tube which has a tensioning and filling/draining device on both ends. During filling, the wall becomes spherically convex and shortens the stretch length. Application of the technical muscles as prosthetic muscles, lifting/tensioning device, spring tensioner and adjuster, positioner and muscle motor, and as robot. For use, a tensioning and filling valve is required. Control is effected via pressure and drainage lines. These are actuated electronically and by control valves. The electronics comprise sensors, receivers and computers. Simple controls are possible mechanically. The pressure is achieved by a pump or gravity/gradient. <IMAGE>
Patent DE-3920415-A1 (DE)
Title: Casting system and device for its execution - where gas pressure is applied to riser after casting, thus reducing required volume of metal in riser and increasing rate of cooling
Inventor: THONI LUDWIG
IPC: B22D27/13
Filed: 1989-06-22
Abstract: After the pouring of the metal into the mould, the riser (i.e. the inlet to the mould) is closed by a ram and pressurised by air or an inert gas to a pressure of 0.5 to 1.0 bar.  An asbestos layer is used to seal the ram to the mould surface. USE/ADVANTAGE - This invention is used in casting of metal objects, where the molten metal is poured into the mould through a riser pipe, and the level of metal in the riser is normally chosen so that its liquid head serves to counteract any shrinkage of the casting during cooling, by supplying further molten metal to make up the loss. Supplying the necessary pressure from an external source means that the level of molten metal in the riser can be reduced.  The rate in cooling is increased and the quantity of metal used is reduced.  The production process is therefore made more efficient.

Inventor: KUMMER MARTIN
IPC: B25F5/02
Filed: 1990-02-02
Abstract: To obtain a more efficient or more compact electric hand machine-tool (1), the flow rate of the cooling air blown by a radial fan (6) is increased.
