Patent DE-4014036-A1 (DE)
Title: Adiabatic combustion engine - comprises silica glass piston and cylinder with surface temps. around 800 degrees celsius
Inventor: STRACH LOTHAR
IPC: F02B75/24
Filed: 1990-05-02
Abstract: The engine comprises contactless silica glass pistons moving in cylinders of the same material, there being two pistons joined to a common connecting rod, the guiding of which is via air bearings. Leakage through the ring gap between pistons and cylinders is sucked away through a further ring gap and through the hollow connecting rod, mixed with incoming fresh air via a stabilising conical ring. The use of air bearings in the engine is possible since no operative components influence the straight line movement. The crank bolts taking up gas force describe an absolutely straight line, and rotate thus with constant angle speed in the roller bearing of the connecting rod with two pistons at each end. USE - As an adiabatic combustion engine.

Title: Control of glass level in glass melting appts. - by weighing glass and appts. to calculate glass wt. and comparing to a preset wt. permitting controlled addn. of raw glass
Inventor: ASAMUMA SHIGERU
IPC: C03B3/00
Filed: 1990-08-31
Abstract: Process and device for controlling the level of molten glass in glass melting equipment. Two methods of determination are suggested.

Addition to raw material is controlled in relation to the wt. comparison. USE/ADVANTAGE - Controls the level of glass in glass melting equipment enabling flow and outlet pressure to be maintained at a constant level. The requirment for a laser, microwave or similar level indicator is unnecessary.

Inventor: OSYPKA THOMAS
IPC: A61M25/01
Filed: 1991-04-26
Abstract: A guide catheter (1) with an inner channel (2) for insertion of a treatment catheter or the like is pre-bent or curved in its region adjacent to the distal outlet end (3) and can be twisted to position it on insertion or in the position of use. In order to avoid the necessity of transmitting the requisite torsional rigidity over the entire length of the wall (7) of the guide catheter (1), a rotating element (8) which is made of a torsionally stable material and which is displaceable inside the guide catheter and can be releasably fixed on its distal end region and which preferably has a slotted end and an expanding part (10) is provided, with which this rotating element (8) can be temporarily clamped on the inside of the wall (7) of the guide catheter (1). It is thus possible to transmit the rotary force via this rotating element (8) onto the guide catheter (1) at a previously selected site, so that the catheter itself does not require any torsional rigidity and can be designed so as to be correspondingly slim and flexible. <IMAGE>

Title: Tubular stretch closed end material smoothing device, for stockings or tights
Inventor: MUELLER WERNER
IPC: D06C5/00
Filed: 1991-09-24
Abstract: The unit(s) feeds and stretches the material on a longitudinal former. The heater heats it on the former. The material is initially gathered to be taken by grips which move along the former to draw the material over it and peel it on.     Pref. the grips are inserted at least partially into the sides of the stocking gathering station to hold the material and spread it outwards, with grip(s) tilting w.r.t. the other against a limit stop to hold the stocking fabric between them. When the gathered stocking has been drawn over the former, the grip is tilted back to release it from the limit stop, and both grips are parallel to each other. The tilting grips is moved alternately between a setting against the limit stop and parallel to the other grip while they are moved along the former, to draw the stocking material over the former. The frequency of the tilting action is controlled w.r.t. the relative speed between the grips and the former. The two outer grips, with a gripping prong, flank a U-shaped gripping head with tilting legs as gripping prongs. Each limit stop is a rubber buffer. The stocking is gathered by two displaced plates with continuous belts between them which project at least partially beyond the plates, with two double-belts with parallel belts where one travels against the other. Guide bars between the plates, over the belts, project at least partially beyond the long end surfaces of the plates. The former has curved U-shaped stretcher(s). A turntable, rotatable on a vertical axis, carries formers (11), with separate stations for the feed and stretching units and the heaters, for the turntable to rotate between them. A unit to withdraw the stocking is after the heater at the former. The stretchers are suspended at the turntable, with their rounded ends downwards. A light unit with a flat illumination is directed at the stocking on the former for visual control. The stretchers swing on a holder at the turntable between an aligned assembly and an assembly pushed to one side of the alignment. The stretchers swing parallel to each other for the stocking to be drawn off at the take-off station by two belts which extract the stocking from the sides of the stretcher, and pass the stocking to a lateral folder with two belts and a folding slide and a stiffening sheet is inserted for packaging.

Inventor: SCHRAUFSTETTER WILFRIED
IPC: C02F11/00
Filed: 1991-10-21
Abstract: A process is disclosed for preparing metal-containing and/or mineral sludges and/or wet metallic or mineral fibrous materials in view of ulterior processing. The sludges and/or fibrous materials are mixed, kneaded and pressed together with hydraulic binders, such as cement, lime or gypsum in a worm extruder, and are extruded as a subsequently processable product. This process allows metal-containing and/or mineral sludges and/or wet metallic or mineral fibrous materials to be prepared in view of ulterior processing in such a manner that they may be reused. The solid, subsequently processable product obtained exits the worm extruder as pellets or rods that are very easy to transport to an ulterior processing plant.

Title: Digital current measurement method - using inductive transducer with measurement current in primary coil, magnetic flux in core compensated by secondary current controlled by counter
Inventor: ROTH-STIELOW JOERG DR ING
IPC: G01R15/18
Filed: 1991-12-20
Abstract: The measurement method involves using an inductive current measurement transducer with the measurement current flowing through a primary winding (3) of the transducer. The count direction of a clocked counter (7) is influenced by the direction of magnetic flux in the transducer core (2). The counter state controls the current in a secondary winding (4) so that the resulting flux compensates that caused by the measurement current. The counter state forms a measurement value corresp. to the measurement current. USE/ADVANTAGE - E.g. for measurements on electric motors. Does not necessitate the use of an analogue-to-digital converter.
