Patent DE-3520935-A1 (DE)
Title: Device for producing a forward propulsion force, especially in space vehicles which are not subject to gravity
Inventor: WOHLFAHRT HERBERT
IPC: B64G1/40
Filed: 1985-06-12
Abstract: In the case of a device for producing a forward propulsion force, especially for controlling space vehicles such as satellites or the like which are not subject to gravity, it is intended to create a solution by means of which the energy produced via reactors, for example electrical energy, can be used to implement controls of such vehicles, to be precise by utilizing mass forces which can usefully be used in the case of intrinsically rotating, flowing fluids. This is achieved in that two cylindrical wheels (5, 6) (which are provided with a large number of [lacuna] between diffuser chambers (16, 16'), which are essentially radial from the centre and are aligned axially at the edges, are arranged in mirror-image symmetry with respect to one another and can rotate) are arranged on a stationary shaft (3), a diffuser channel (13) being provided in the stationary shaft (3), which diffuser channel (13) connects at least one diffuser chamber (16) in one cylindrical wheel (5) to another diffuser chamber (16') in the other cylindrical wheel (6), the diffuser channel (13) and diffuser channel (16) being filled with a hydraulic fluid, and the two cylindrical wheels (5 and 6) being arranged such that they can be driven in the opposite direction at different speeds. <IMAGE>
Patent DE-3526291-A1 (DE)
Title: Process for smelting steel in a converter with an oxygen top-blowing tuyere
Inventor: DEMIDOV KONSTANTIN NIKOLAEVIC
IPC: C21C5/56
Filed: 1985-07-23
Abstract: The process comprises refining metal consisting of a metallic charge containing scrap and crude iron. The scrap is preheated. The preheating of the scrap is effected by the heat generated on combustion of a solid carbonaceous fuel, fed to the converter, in an oxygen stream which is fed at a rate of 8 to 15 Nm<3>/minute per 1 tonne of scrap from a tuyere which is set up at a height of 50 to 100 reduced calibres above the plane of the converter bottom. In this case, the fuel stream crosses the oxygen stream. Lime is charged on top of the heated scrap and crude iron is then poured in. The refining of metal starts at a tuyere set-up at a height which exceeds its working height by a factor of 1.5 to 2.5. The tuyere is set up in its working position by uniformly lowering it without shocks, starting at the time when the oxygen has been consumed down to 5 to 10% of its total quantity required for the refining, and it is ended after 20 to 25% of the total quantity of oxygen required for the refining has been consumed.

Title: Glass gable roof air collector for supplying a heat pump or a heat exchanger
Inventor: OTTENSMEYER HANS-ULRICH DIPL I
IPC: E04D13/18
Filed: 1986-03-12
Abstract: The present invention describes a roof heating system in which air heated by the sun is used as the energy source. Compared with the prior art, a very cost-effective construction has been developed here, which is optimal in relation to efficiency and output and fits harmoniously into the existing architecture. The entire area of a building roof exposed to the sun is converted by a darkly coloured substructure with glass cover to an air collector, in which the highest temperature is automatically developed by thermodynamic effects in front of a heat exchanger (heat pump) to be arranged under the ridge on one gable side. Heating and/or domestic water can thus be heated up inexpensively. In terms of building physics, this construction presents no problems since the roof construction remains unaltered and optimum moisture discharge is ensured.

Title: Driver with overload protection
Inventor: BUECHNER WOLFGANG
IPC: B65G19/26
Filed: 1986-10-11
Abstract: The driver with overload protection is used in conveying installations preferably for conveying material 1 of the printing trade between processing machines of the printing trade. The object of the invention is to bring about a reduction in down times and repair times and a saving of material by means of a rationalisation of the conveying process. For this purpose, according to the invention, the overload protection of the conveying installation, which hitherto was located in the drive element, is transferred into each transport element, with the aim that the ability of this overload protection to differentiate between starting and stopping moments be pronounced, independently of the number of conveying elements. Furthermore, it becomes possible, by locking the deflected driver 2 by means of an overload protection 12, to determine where a selected deceleration moment is exceeded and, by means of an adjustable overload protection switch 16, to trigger the shutting-down of the conveying installation. <IMAGE>

Title: Tensioning device for safety belts
Inventor: SCHWANT WILFRIED DIPL ING
IPC: F15B15/19
Filed: 1986-10-15
Abstract: A tensioning device for safety belts for vehicles, especially cars, is described, which has a piston which engages on the safety belt and can be displaced in the belt-tensioning direction in a casing by means of a propellant charge which can be triggered by a sensor. In order to reduce the piston forces, which are generated when the propellant charge is triggered, and to make them uniform over the entire path of the piston, the piston (3) is to have at least two effective surfaces (7, 8) which are subjected to the propellant charge one after the other for pressurisation. In this process, the first effective surface (7) can be constantly subjected to the gas pressure generated by the propellant charge, while the second effective surface (8) is only subjected to the gas pressure generated by the propellant charge when the piston (3) has covered a prescribed distance. <IMAGE>

Title: Femoral part of a hip joint endoprosthesis
Inventor: WITZEL ULRICH DR ING
IPC: A61F2/32
Filed: 1987-10-27
Abstract: A femoral part of a hip joint endoprosthesis has a metal stem with a core which integrally interconnects axial elements arranged on its edge over the entire stem area. In the distal region of the stem, each cup element has a convex outer bearing surface adapted to suit the course of the inner surface area of the cortical substance. The axially extending narrow surfaces, which face each other, of adjacent cup elements each leave a peripheral gap between them for the reception of bone marrow and spongiosa. The stem cross-section of the distal area continuously decreases towards the distal end down to a minimum cross-section related to the fabrication. The femoral part permits physiologically optimum transmission of the hip force onto the femur and necessitates only a small loss of bone substance during implantation.
