Patent DE-3333917-A1 (DE)
Title: Heating boiler - universal - all-purpose burner
Inventor: WEBER GAUTHIER
IPC: F24B13/00
Filed: 1983-09-20
Abstract: The functioning of the boiler takes place basically according to the physical laws, both in the combustion process and in the fuel supply. The shape of the water boiler, in combination with the location of the combustion process, ensure an environment-friendly combustion of the materials, an optimum utilisation of the fuels through the throttling down to low temperature combustion: the precondition for increasing the efficiency. By the uninterrupted combustion and the uniformity of the flue gases flowing past under the boiler floor and inner wall a twofold and threefold heat transfer is possible for the first time. The shape of the boiler, the location of the combustion process, and of the filling space first make possible an interaction of all physical possibilities which make possible a large saving of fuel. The production of the boiler is economical, since little material is required. No casting moulds are necessary. The wall of the filling space is in two parts, for transport facilitation and saving. In spite of the combustion of heating oils, no burner is required. The boiler is an alternative for energy supply and our environment.

Title: Shooting goal
Inventor: BOEKELS BERNHARD
IPC: A63B63/00
Filed: 1983-12-13
Abstract: The shooting goal, cf. drawing Fig. A, is a flat, collapsible goal with a target disc (5) which has target holes (6) through which the ball can pass and which are secured at the back by catching baskets (7), this target disc (5) being suspended on springs (4) in a mountable frame (1) over which a net (3) is stretched. On this frame (1), in order to widen the ball trapping area, wing frames (2) over which a net (3) is likewise stretched are attached at the sides, these also being mountable, adjustable and fixable, and being secured together by means of supports (8). When assembled, a shooting goal stops a ball flying into the target, and to a limited extent even a misdirected ball, and hence offers increased safety during ball games. If the goal is provided with a ball guidance system (which is not a subject of this application), any escape by a ball is prevented. Possible uses are for sport and leisure, football and handball games, especially where a playing area is limited in space, e.g. in a cellar, courtyard or garden or on a beach, etc., or requires special safety precautions. In a miniaturised design, a shooting goal is designed as a table football appliance. <IMAGE>
Patent DE-3345524-A1 (DE)
Title: Clutch for vehicles, especially motor vehicles
Inventor: JANTHUR INGO W DIPL ING
IPC: F16D47/06
Filed: 1983-12-16
Abstract: A motor vehicle clutch comprising a hydrodynamic and a mechanical clutch part has locking pawls, automatically connecting the two clutch parts when the engine is at a standstill, as a parking mechanism. The locking pawls are each integrally connected to a respective weight, which places the centre of gravity of the locking pawls radially outside the swivel axis of the respective locking pawl in such a way that, in the event of decelerations of the drive side of the hydrodynamic clutch due to a mass moment of inertia, the locking pawls are held in their unlocked swivel position until the drive side (engine) has come completely or almost completely to a standstill. In this way, heavy impact loads and thereby damage of the locking pawls are advantageously prevented, which would otherwise occur in the event of unintentional engine decelerations, especially in the event of a stalling of the engine.

Title: Closing device for curtain compartments suspended in a row below a roof
Inventor: JENSEN NIELS THORKILD
IPC: A01G9/22
Filed: 1984-02-07
Abstract: A closing device for curtain compartments (2, 3), suspended below a glass roof, with fastened rear edges. The front edges of the compartments can be drawn by means of a leader (20) of a row of draw cords (12), arranged in parallel, along a fixed path for the tight engagement with the rear edge of a curtain compartment arranged ahead of it in the drawing direction. Rear-edge supports (25) which are tensioned at the rear lug of each curtain compartment (2) are suspended on a support cord (24), extending transversely to the draw cords, by means of a bar (30) which extends around the leader (20). Two draw parts (18, 19) are mounted firmly on the leader (20). The front draw part (18) is arranged in such a way that it can press the bar towards the rear, i.e. in the drawing direction, when the curtains are almost drawn. As a result, the rear-edge support tilts upwards against the front lug (34) of each curtain compartment (3), said lug now turning towards it, for mutual sealing of the two curtain compartments. When the curtain compartments are drawn away, the rear draw part (19) strikes against the bar (30) and thus tilts the rear-edge support forwards so that the folds (35) of the curtain compartments are pressed against the rear-edge support which is tilted forwards. As a result, it is ensured in a simple manner that the folds, seen in the longitudinal direction of the roof, take up the smallest possible space and thus cause the least degree of shade.   <IMAGE>

Filed: 1984-05-11
Abstract: In the case of an accumulator, said accumulator can be connected via a relay switch to a load, the coil of the relay being connected in series with a switching-on contact between the poles of the accumulator. In order that the circuit to the load is opened in the event of an unacceptable reduction in the accumulator voltage, and in order that this interruption is maintained even when the accumulator voltage rises again, a protection circuit is provided. Said protection circuit consists of a voltage comparator circuit which is connected between the poles of the accumulator and which, if the accumulator voltage falls below a first level, switches from a first switching state into a second switching state. This second switching state is stored in a memory of a memory switch whose switch is connected in series with the switching-on contact. This switch opens when the memory stores the second switching state. The storage of the second switching state is not deleted again until the switching-on contact is opened.

Title: Method for measuring quantities of milk
Inventor: SCHOLTYSIK BERND DR
IPC: G01N33/04
Filed: 1984-06-30
Abstract: The invention relates to a method for measuring the quantities of milk provided by cows during a milking time. The method consists in that the milk is guided into a receptacle, the outlet aperture of which is controlled by a valve on the basis of a measurement of the milk level carried out with a sensor in such a way that the level of milk in the receptacle is constantly between two limiting values. During the open phases of the valve, the outflowing volume stream is determined from the measured milk level, and the volume of milk which has flown out is determined by including the time factor. The residual quantity of milk remaining in the receptacle at the end of the milking process is determined from the measured milk level and the cross-sectional area of the receptacle. The invention is designed in such a way that the milking vacuum is not affected, thereby avoiding impairment of removal of milk from the udder. The invention also makes it possible to obtain a sample of milk from the total quantity of milk, which sample can be used to analyse the constituents of the milk.

Title: Process for the production of preforms from clear glass for the production of optical fibres
Inventor: AULICH HUBERT DR
IPC: C03C13/04
Filed: 1984-09-28
Abstract: A process is described for the production of a preform from clear glass for the production of optical fibres for optical communications technology, in which the starting material used for the formation of the preform is highly pure SiO2 in the form of solid glass particles which is produced by the so-called fibre leaching process. The aim is to provide an inexpensive process of this type which is particularly suitable for the production of preforms for monomodal fibres, the fibre type which is the most favourable for long transmission distances in, in particular, postal transmission systems. To this end, a moulding is first produced from the glass material by sintering in a hollow mould, and the moulding is sintered to completion after removal from the hollow mould to give the clear preform. In order to be able to generate the variously doped regions of the fibre to be produced, a hollow mould divided by partitions into hollow sub-moulds which are filled with doped glass material obtained from the starting material is used. <IMAGE>
