Abstract: PCT No. PCT/DE89/00533 Sec. 371 Date Apr. 13, 1990 Sec. 102(e) Date Apr. 13, 1990 PCT Filed Aug. 14, 1989 PCT Pub. No. WO90/02309 PCT Pub. Date Mar. 8, 1990.The invention relates to an impact fuse (2) having fore-bore safety for a projectile (1), comprising a percussion needle (3) stationary on the fuse and an impact body (4) containing a percussion cap (5) and supported slidingly in the direction of flight, as well as a race for a blocking ball (23) between the impact body and the inner wall of the projectile casing.

Patent DE-3828914-A1 (DE)
Title: Conveyor belt
Inventor: RAU HERBERT
IPC: B65G17/06
Filed: 1988-08-26
Abstract: It is known, in the case of conveyor belts which are equipped with a multiplicity of plates arranged between two roller chains, to configure the plates so that they are easily replaceable, for example in that the plates are manufactured from elastically flexible material and the possibility thus exists of inserting the plates by temporary, arcuate bending of the latter between the pairs of bolts which are provided on the two roller chains. This type of fastening requires that the plates consist of elastically flexible material, a condition which, according to experience, cannot always be fulfilled. The object thus existed of configuring the connection between the plates and the bolts of the roller chains in such a manner that easy replaceability can be achieved even in the case of plates not consisting of flexible materials. According to the present invention, this object is achieved in that, on the two end faces of the plates (1), in each case two recesses (4) corresponding to the bolts (3) are provided, having a gap (5) opening below, the approximately trapezium-shaped cross-section of which narrows towards the inside of the recess (4) in such a manner that the remaining clear width of the gap (5) is a small amount smaller than the diameter of the bolts (3), and thus a positive-locking connection, capable of locking, between the bolts (3) and the plate (1) is formed. <IMAGE>

For receiving multiple holders outside the measuring instrument, a stand is provided. Both on the holder and on the stand and support element, special provisions are made for positioning of the specimen containers both in the stand and in the support element in a way that both assures satisfactory measurement and precludes any mistake in the order of the specimen containers during the measurement or during the preparatory steps in the process. This system is suitable for performing chemiluminescence immunoassays, for instance.
Patent DE-3836461-A1 (DE)
Title: Low-temperature steam generator
Inventor: GELESIC ANTUN DIPL ING
IPC: F22B3/04
Filed: 1988-10-26
Abstract: The low-temperature steam generator has an upright cylindrical housing (1) which is subdivided into a top and bottom chamber by a horizontal dividing wall (4) forming a central opening (5). An inlet line (2) leads tangentially into the top chamber, while an outlet line (3) leads tangentially out of the bottom chamber. A spiral flow forms in the top chamber, the velocity of which increases in the direction of the central opening (5) of the dividing wall. The pressure in the liquid, which is close to its boiling point, accordingly drops and steam generation occurs. The steam is drawn off through a steam outlet pipe (6) leading out of the top of the top chamber. A spiral flow also forms in the bottom chamber. This spiral flow goes from the central opening (5) to the outlet line (3). Its velocity decreases so that the pressure in the liquid increases in the direction of the outlet line. <IMAGE>

Title: Method for the control of the preheating of the gas in gas-pressure control systems
Inventor: STIRNBERG DIETER DR ING
IPC: G05D23/19
Filed: 1988-10-27
Abstract: In the pre-heating of the gas in gas-pressure control systems, a control method is applied according to which the temperature difference between feed and return of the heat exchanger is adjusted taking into account the desired heat quantity necessary for the heating of the gas, and according to which the boilers supplying the heat exchanger are driven in on-off operation. This control method has an optimal control quality of the output temperature, since at each point in time the quantity of energy which is required by the gas for heating up is sent into the preheater. In the case of varying energy requirements, the output temperature is altered correspondingly so that, at the moment of the load change, the changed energy demand is already calculated and the entire system is correspondingly adjusted. The quantity of energy pre-held in the boilers is kept to the absolutely lowest level, by which means the energy lost to the environment is reduced, just as by means of the complete shut-down of the boilers in times when, as in summer, preheating is unnecessary. <IMAGE>

Patent DE-3837982-A1 (DE)
Title: Pressure-relief valve for hydraulic support systems, in particular for use as a rock-burst valve
Inventor: SCHULZE FORSTHOEVEL ROBERT
IPC: E21D15/51
Filed: 1988-11-09
Abstract: The invention relates to a pressure-relief valve for hydraulic support systems which is preferably used as a rock-burst valve. The closing body (8) of the valve is partly pressure-compensated with the use of a compensating piston (10); it is loaded on the one hand in the opening direction by the hydraulic pressure at the valve inlet (6) and on the other hand in the closing direction from the rear side via the compensating piston (10), the pressure-compensation space (17) which accommodates the compensating piston (10) being connected to the valve inlet side (6) via an axial connecting passage (25). According to the invention, a stop valve (24) controlled by the hydraulic system pressure (prop pressure) is allocated to the pressure-compensation space (17). In the event of an overload, the stop valve (24) suddenly relieves the pressure-compensation space (17) so that the closing body (8) lifts from its valve seat (7) and opens the discharge of the pressure fluid towards the valve outlet (9). As soon as the pressure in the hydraulic system (prop pressure space) has fallen again to a preset value, the hydraulically releasable valve (24) closes again so that the pressure at the valve inlet side can build up again in the pressure-compensation space, which pressure puts the pressure-relief valve into the closed position. <IMAGE>
