Title: Method and circuit for connecting a controller of a digital computing system to a computer bus in a manner favouring priority
Inventor: MUELLER OTTO
IPC: G06F13/30
Filed: 1981-09-04
Abstract: The controller of a digital computing system is connected to a computer bus in a manner favouring priority by a request (DMA) of the controller to access the computer bus being signalled to the central computing unit (CU), which is stopped for the duration of one storage cycle, it being the case during this time that the controller is connected to the computer bus (DMA cycle). After termination of the DMA cycle, the access request (DMA) is cleared and the central processing unit (CPU) executes a new cycle. A priority coding can be undertaken on each circuitboard of a controller by means of a priority plug (4), with the result that when an access request is logged, a check is firstly made on all the circuitboards of all the controllers as to which priority this access request has. The priority of this access request is compared with the priority of the relevant controller - and if the external priority is higher the controller with the higher priority is authorised to execute its DMA cycle. <IMAGE>

Title: Process and device for producing a strewing sieve from plastic
Inventor: HAGEN NORBERT
IPC: B26F1/02
Filed: 1982-03-10
Abstract: In a process and a device for producing a strewing sieve from plastic by injection moulding, material sections are removed by a punching operation to form the holes of the strewing sieve. Directly following the punching operation, the material sections are again moved back into the holes where they are each held by friction so that each hole represents a seat for a closure plug formed by the material section, which closure plug can be removed in a simple manner by the user of the container provided with the strewing sieve. Production and reclosing of the holes can be carried out in a special punching die after production of the strewing sieve body. However, particularly for large series, it is possible to provide the injection mould itself with a corresponding punching die.

Title: Combined rocket drive system
Inventor: TEINZER HARALD
IPC: F02K9/80
Filed: 1982-03-27
Abstract: The combined rocket drive system is a combination of a solid drive and a ram jet drive. It is intended to be used in conjunction with an optical fibre control system, since the hot driving gases leave the missile in the shape of a bell, and an optical fibre for control purposes can be unwound safely in the relatively cool centre of this bell. The exhaust gases of the solid rockets are in this case ducted via a conical body into a sheath which is constructed as a ram jet drive, and leave the ram jet motor nozzle in the shape of a bell. The conical body can be moved into the solid rocket nozzle in a reciprocating manner in order to control the thrust and hence the speed.

Patent DE-3312544-A1 (DE)
Title: Means of noise reduction on concrete-stone moulding machines
Inventor: BAIERL THOMAS DIPL ING
IPC: B28B1/08
Filed: 1983-04-07
Abstract: For reduction of the noise, caused by the impact of the mould on the vibrating table during the compaction operation, in other words in the vibration phase, the mould, in particular the mould frame 2, is provided with damping material or an elastic layer 5 which can consist of a natural or synthetic material, e.g. rubber, Vulkolan or latex, generally or another material, counter-sheets 6 being mounted on this coating for more intensive reduction of the noise radiation. In order then also to reduce the structure-borne noise transmission of the actual noise-generating mould insert 3 to the parts adjoining it, in other words the mould frame 2, mounting an elastic intermediate layer or coating in the same manner between these two parts is also to be envisaged. In order to guarantee a complete noise decoupling, the connection elements also, e.g. the screws 4, are advantageously provided with an elastic intermediate layer. In this manner, it is ensured that noise bridges no longer exist between mould insert 3 on the one hand and mould frame 2 on the other hand, and that these parts are acoustically completely decoupled from one another. As a result of this necessary decoupling, however, it is necessary to interconnect the mould frame 2 and the mould insert 3 detachably, as a result of which there is the further advantage that the mould frame 2 can be used for mould inserts of different stone profiles as well as of different stone heights ...
