Patent DE-3740558-A1 (DE)
Inventor: GUSTAFSSON LENNART
IPC: B65G1/04
Filed: 1987-11-30
Abstract: A load carrier comprises part of a vehicle which transports goods in a preferably automated high-stand storage facility having shelf compartments (24) carried by uprights (20). There is a coordinate system of reflective gauge points (23), on the uprights, and fixed reference points (22) located close to the floor. The reference points (22) are detected by a photocell on the vehicle chassis, whereas the gauge points (23) are detected by a photocell mounted on the vertically movable load carrier. A computer computes the positional difference between a fixed reference point and gauge points located immediately thereabove. These differences are used to determine the actual position of each shelf compartment while taking into account misalignment and outward bending of the uprights. The differences are stored in the computer memory, measuring operations being carried out at any convenient time. <IMAGE>

Patent DE-3809633-A1 (DE)
Title: Shift register-adder circuit in 54321 code
Inventor: MERKLE PAUL
IPC: G06F7/50
Filed: 1988-03-22
Abstract: In the shift register-adder circuit according to the subject of the invention, the addition is done in almost the same way as in the shift register-adder circuit according to P 3809632.3. There is a difference, in that the high potentials, or the flipflops which have high potential at their working outputs, do not form a closed column, because either no flipflop or only one flipflop or at most only two flipflops are triggered with high potential. Therefore, in this adder circuit, not all high potentials collect to the right, but the displacement stops even when the high potential of the A summand enters flipflop (21). A flipflop of shift register (2) has a "high potential content" in the case shown if its right-side output has high potential, because the right-side outputs are the working outputs. <IMAGE>
Patent DE-3820673-A1 (DE)
Title: Process for erecting explosion barriers in underground mining operations
Inventor: HANNES KLAUS DIPL ING DR
IPC: E21F5/14
Filed: 1988-06-18
Abstract: The explosion barrier serves to restrict the spread of a flame or explosion front, with a curtain of a barrier medium being dropped across the cross-section of the road. The barrier medium used is a pulverulent and/or granulated hydrate, in particular one containing at least 15% of water of hydration. This medium has a high specific heat absorption capacity and can accordingly withdraw a large amount of heat from the flame and explosion front. For such explosion barriers, the servicing is extremely small since the water of hydration bound in the hydrate does not evaporate or hardly evaporates under the conditions of the normally ventilated road. The costs of the barrier medium are minimised by use of flue-gas desulphurisation plant gypsum in dihydrate form.
Patent DE-3822160-A1 (DE)
Title: Method and device for adjusting a nozzle head
Inventor: JAKOB DIETER DIPL ING
IPC: B05B1/30
Filed: 1988-06-30
Abstract: The invention relates to a method for adjusting a nozzle head, in which the extinguishing medium firstly emerges as a fanned-out spray jet which then merges into a compact hollow jet when the nozzle is adjusted further. A nozzle head according to the invention is seen in that a valve body, attached at the end face, with an adjustable sleeve on the one hand forms a tightly closing valve seat and then, by adjustment, guides the extinguishing medium inwards via an annular groove in the valve body and then outwards again via a transition cross-section and thus produces the widely fanned-out spray jet. A front cylindrical surface of the valve body forms, together with a cylindrical surface of the adjusting sleeve, an annular slot to form a compact hollow jet.

Patent DE-3900206-A1 (DE)
Title: Temporarily stable cores for the formation of cavity chambers, and cavity body components in elastomeric, thermoplastic-elastomeric and thermoplastic sealing profiles
IPC: B29C33/52
Filed: 1989-01-05
Abstract: Sealing profiles with cavity chamber components have hitherto been proposed by manual gluing techniques, vulcanising-in of highly porous cores or vulcanisation with removable metal cores. A disadvantage is that either glueing points are introduced as weak points into the system, or that the functioning of the cavity chamber is no longer fully ensured. The object is achieved in such a way that lithogenic core materials are shaped with temporary binders to give cores of variable initial stability, whose stability slowly decreases as a result of pressure and temperature. This has the result that, at the end of the casting process, the cores can be decomposed into dust-like components which remain in the cavity chamber or are rinsed out with water. Temporarily stable cores are particularly suitable for the manufacture of sealing profiles, whose cavity chambers are to be subjected to pressure and are to be adapted to variable surrounding conditions. In this way, even fabrication tolerances in the systems, in which the sealing profiles are used, can be widened.
