Title: Hierarchical multi-processor system with system bus and local bus structures based on the VME bus specification
Inventor: LEMPPENAU WOLFRAM DIPL ING
IPC: G06F13/40
Filed: 1985-04-16
Abstract: In data processing and in process and control engineering, multiprocessor systems are used for processing input data in parallel with a high real-time requirement/resolution and making the result data available. The performance of such multi-processor systems can be optimised with respect to data preprocessing, data concentration and final data processing if their system structure can be flexibly adapted to the respective requirements on the basis of a hierarchical bus system for inter-processor communication. Selecting the VME bus specification for all bus systems within a hierarchical multi-processor system with arbitrary system bus and local bus structures makes it possible to implement complex but structurally very simple and inexpensive systems in the logical structure.

Title: Lapping or polishing tool
Inventor: STEINER JOHANN
IPC: B24B37/00
Filed: 1985-05-21
Abstract: The invention relates to a lapping or polishing tool which is meant preferably for clamping into a hand-operated filing machine. The object of the invention is to provide lapping or polishing tools which no longer exhibit the outlined, undesirable overstressing of the edge zones of the lapping surfaces and can be mutually exchanged by one manipulation, with the result that even precise surfaces having defined qualities may be produced by unskilled workers after a very short training period. This object is achieved according to the invention in that the working surface of the lapping-tool element is subdivided into one or more rectilinear, annular or polygonal strip-shaped zones, and that a downwardly closed ball socket with an undercut is articulated on the upper side of said element. Said ball socket consists of a suitable plastic and is used for the catch-locking, and thus securing, of the ball head of a feed rod which, for its part, is preferably clamped into a hand-operated filing machine.

Patent DE-3525481-A1 (DE)
Title: Parking disc
Inventor: QUANTE HEINRICH
IPC: G07C1/30
Filed: 1985-07-17
Abstract: To monitor a fixed-time charge-free parking permit, there is a parking disc in which the disc has a drive which is designed as a timing device which, via a changeover switch, acts, on the one hand, on the disc while the vehicle is travelling and, on the other hand, when it is at a standstill, on a second measuring device with a memory, indicating the corresponding time. Both the arrival time and the parking period are thereby recorded, so that, when the vehicle is started up again, the parking period recorded in the memory is added to the recorded clock time and, at the same time, an exact time indication is consequently obtained again, so that the device is at the same time switched on again for a new parking time. <IMAGE>

Title: Device for setting a switch to a zero-position bit pattern of a stepping motor
Inventor: JANSSEN REINER DIPL ING
IPC: B41J29/38
Filed: 1985-10-05
Abstract: In the production of electronic typewriters or office machines of similar design, particular setting operations are necessary, e.g. the setting of the zero-position switch of the horizontal drive to a zero-position bit pattern of the stepping motor. For this purpose, complex measuring equipment and expensive aids are conventionally required in order to indicate the electrical state of the apparatus in each case during the setting. The invention is based on the object of simplifying the abovementioned setting of the zero-position switch and making it less expensive. This object is achieved in that the switch (34) can be actuated by the movable component (4) in the outermost edge position, and in that the position of the switch (34) can be scanned by the activated microprocessor (20) and can be indicated in the closed position in a display (25) which, during the printing operation, indicates a different operating state of the machine. The setting of the zero-position switch to a zero-position bit pattern of the stepping motor is thus very simple without requiring measuring apparatuses to be connected to the electronic devices of the machine for this purpose. Additionally, the setting of the zero-position switch is also possible at the customer's premises. Considerable cost savings are thus achieved. <IMAGE>

Title: Kit of centrifugal pumps
Inventor: RIESTER PETER
IPC: F04D29/62
Filed: 1986-03-12
Abstract: In a kit of centrifugal pumps with impellers of different external diameters and also, depending thereon, spiral housings of different diameters, the impellers being provided on the rear side with rear blades which extend as far as the external diameter and which, with a small spacing, run past an inner plane surface of the pump cover closing off the rear side of the centrifugal pump, the aim is to reduce the number of individual parts. To this end, it is proposed that, within the kit, a uniform size of the pump cover covering the rear side of the centrifugal pump is present, that the size of the pump cover is adapted to the impeller with the smallest external diameter and thus also to the smallest spiral housing, and that, in the case of the other pump sizes with greater impeller diameter and greater spiral housing diameter, an intermediate ring is mounted on the pump cover to adapt the inner plane surface to the greater impeller diameter and to bridge the spacing to the greater spiral housing diameter.

Title: Directional control valve
Inventor: HAHMANN WOLFGANG DR ING
IPC: F15B13/043
Filed: 1986-08-29
Abstract: The invention relates to a hydraulic directional control valve. With the directional control valve, in which two control spools are guided in alignment in a control bore of the valve housing and are actuated by associated pilot-control valves in order to control consumer connections, several consumers can be activated independently of one another. Hitherto, several valves were necessary for this purpose. Control tasks in which working speeds occur from creep motion via the operation at normal speed up to rapid traverse and in opposite working directions can therefore be achieved by the novel directional control valve at a low construction cost. In a further embodiment of the directional control valve, the control spools are arranged in the control bore in such a way that their facing abutting ends touch when the magnets allocated to the actuating devices are loaded with a certain closed-circuit current and are activated by the respectively set current in such a way that they are mutually displaced in such a way that several connected consumers can be controlled.
