Patent DE-3628286-A1 (DE)
Title: Processor with integrated memory
Inventor: STAERK JUERGEN DIPL ING
IPC: G09G5/393
Filed: 1986-08-20
Abstract: Traditional raster displays have a separate graphics processor and image memory. The image memory is connected to the graphics processor by, e.g., an 8, 16 or 32 bit data bus. The principal disadvantage of such arrangements is that only a limited number of pixels, depending on the bus width, can be modified. The object of the invention is to extend the possibilities of access to the contents of the image memory. This is achieved by integrating the processor, or its data-manipulating unit, and the image memory on one chip. It is thus possible to address and modify lines or columns or parts of them, or blocks of memory cells or pixels. The increased performance is achieved by:     - a special structure, - the structure of the image memory, which is quite different from a conventional memory,   - the special addressing logic and - the greatly increased data bus width, which is only possible on one chip.   The main application field is in raster graphics, e.g. microcomputers, terminals or other raster scan converters.

Title: Device for protecting against copying
Inventor: ORTMEIER WILLIBALD
IPC: A47G5/00
Filed: 1986-08-26
Abstract: The device for protecting against copying, which can be folded open and shut and is composed of a box (see drawing - a and b), of which the lid can be folded open and shut, a holding bar (see drawing - c), a snap catch (see drawing - d) and a screen area (see drawing - e) formed from non-transparent, folded material capable of opening like a fan, and fixed in the interior of the box and to the underside of the lid and capable of opening with the opening of the lid and folding up with the closing of the lid, prevents, in the folded-open state, impermissible copying from the neighbour at table or on the part of the neighbour at table (cribbing), in particular during tests, schoolwork and examinations in schools and easily fits, in the folded-shut state, into a schoolbag. By virtue of the various adjustment possibilities of the holding bar, the screen area can be enlarged or reduced according to requirements. The possibility of being able to fold open the box lid, and the screen area attached thereto, also beyond an angle of 90 degrees prevents copying on the part of the neighbour at table diagonally from behind. <IMAGE>

Title: Pressure-surge protection for liquid-filled pipelines in heat-supply systems
Inventor: GNUECHTEL STEFAN DR ING
IPC: F17D1/20
Filed: 1986-11-14
Abstract: The invention specifies pressure-surge protection for liquid-filled pipelines in heat networks, pressure-keeping means operated in parallel being provided for heat-generating units working in combination, with the aim of avoiding the pressure-keeping means counteracting one another and thus avoiding vibrations in the network as well as of reducing pressure surges, caused by a change in the flow velocity, with uncomplicated components working in a trouble-free and maintainance-free manner. According to the invention the pipeline network, via a distance pipeline in which a constant choke is arranged, is connected to a stepped rising pipe which is widened towards the top and the bottom narrower part of which is partly filled with water. The rising pipe leads into an overflow tank or a compression tank. The pressure keeping for the system is effected via a single pressure-keeping unit. The control according to the invention enables the pressure-keeping vessels of pressure-keeping units of the other heat generators, at a slightly fluctuating high level of filling, to be constantly filled at essentially the same delivery volume via the return pumps and emptied via the initial water pumps.

Title: Method of determining the electrical properties, that is to say the material quality, of a body having any shape whatsoever
Inventor: BLUM RAINER DR ING
IPC: G01N3/32
Filed: 1987-03-05
Abstract: The quality of the material of a body can be determined by vibrations. The material properties are determined by measuring a vibration response after a vibration has been excited. To avoid dynamic interactions between the body and its supports, the body is supported only at those points at which it is at rest after the vibration has been excited. This condition is fulfilled only in the free node lines of the resonance vibration. The support points are found by theoretical calculations.

Title: Process and apparatus for leaching metal-containing, non-predried raw materials
Inventor: ESNA-ASHARI MOHAMMED DR
IPC: C22B21/00
Filed: 1987-06-30
Abstract: In order to be able to successfully leach metal-containing, non-predried raw materials, in particular bauxite, the raw materials must previously be subjected to a sufficiently fine preliminary crushing. For this purpose, a plurality of preliminary crushing and fine grinding units are often required in order to achieve a satisfactory fineness of the raw materials for the subsequent solution and digestion process in the leaching. However, according to the invention, the non-predried raw materials are subjected before leaching to a high-pressure material bed crushing in a roller press (1), and the crushing product in pieces is brought into contact with the solvent without further grinding in a leaching vessel (3) equipped with a stirrer (4) and solid discharge screw (5). As a result of the high-pressure material bed crushing in the roller press, in addition to a sufficiently fine comminution of the grains, microcracks are highly advantageously caused in the solid particles and, as a result, a high metal yield is achieved with considerable saving of grinding energy. <IMAGE>

Patent DE-3731867-A1 (DE)
Title: Container for the disposal and transportation of waste products
Inventor: BROSCH WILFRIED DIPL ING
IPC: B65D90/10
Filed: 1987-09-22
Abstract: In such containers, there is a constant risk to the user that gases arising or, in the case of ignition, flames escape from the filling opening because there is a direct access to the inside of the container during filling. The known measures to reduce this risk, i.e. a non-return valve or deeply penetrating inlet parts or a liquid receiving tank, necessitate great constructional outlay and detract from the operating convenience and functional reliability. The new container is to be user-friendly and safer. In order to rule out any reflux from the filling opening and nevertheless to guarantee a high degree of operating convenience, the filling device (E) is designed as a lock (S) in which the lid (5) and closure (V) can only be opened alternately. Owing to the lock which, from the outset, prevents direct access to the inside of the container, the container is suitable for the disposal, storage and transportation of waste substances and dangerous products of most risk categories (Figure 1). <IMAGE>

Title: (Mini-) device for motor vehicles for deflecting rainwater, snow and slush
IPC: B60R19/54
Filed: 1987-10-01
Abstract: The invention relates to a device on motor vehicles (cars and lorries), which is constructionally designed, mainly intended for winter use, so that per motor vehicle a small clearing effect (deflecting effect) of snow, slush and also rainwater towards the edge of the roadway takes place. This device, e.g. a flexible metal sheet set at an angle, is fixed in the case of motor vehicles, e.g. to the steering knuckles, to the rigid axles or to the underride protector, or the mud flaps are constructionally designed so that they can additionally take on this task. This is achieved in that, per motor vehicle, although only a small clearing effect (deflecting effect) towards the edge of the roadway takes place, given sufficient participation a substantial improvement in the winter traffic situation would be obtained; at relatively little cost per motor vehicle.

Title: Hair-drying air hood structure having a plurality of drying zones with an air flow which can be regulated individually in each zone manually
Inventor: RADEBOLD CLAUS
IPC: A45D20/26
Filed: 1987-10-21
Abstract: The hair-drying air hood structure, in which firstly a stable hood shape is produced by means of a motor, which is suspended from the person, with a fan and heating element - based on interconnected struts filled with air, is supplemented by a switch by means of which it is possible to introduce the air or hot-air flow manually and infinitely variably into different zones of the hair-drying hood and to regulate them independently of one another. Depending on the length, thickness and structure of the hair, the drying operation can thus be selected accordingly in the individual zones such that consideration can be given to the individual requirements placed on the drying operation by the individual person.   For example, parts of the hair which are already dry can be prevented from having to be treated further and thus overdried - which is unfavourable in terms of care - because the drying of other parts of the hair has not yet been completed. Alternatively, simultaneous completion of the drying operation can be achieved in that, from the outset, different intensities of the air flows in the individual zones can be set. Using an air vane switch, partly in conjunction with a thermostat, automatically ensures even supply of air or hot air - regardless of the intensity of the air flow selected in any individual zone.

Filed: 1988-02-25
Abstract: A chuck jaw (53) has an exchangeable jaw (32) and a support jaw (54). The support jaw (54) has a seat for accommodating the exchangeable jaw (32). The seat is formed by a first bearing surface (55), which runs essentially at right angles to the chucking direction of the chuck jaw, and by a second bearing surface (56) which runs essentially at right angles to the first bearing surface (55). The exchangeable jaw (32) has a first and second mating surface (35, 36) allocated to the first and second bearing surface (55, 56). Furthermore, the chuck jaw (30) has a holding device (37), which is connected in one piece to the exchangeable jaw (32) and projects beyond the second mating surface (36), and a locking device which is arranged on the support jaw (54) and serves to releasably lock the holding device (37). The holding device (37) and the locking device come into engagement with one another by putting the exchangeable jaw (32) onto the support jaw (54) at right angles to the chucking direction of the chuck jaw (30). A chuck jaw of this type permits a quick and reliable exchange of the exchangeable jaw. The time-consuming shifting of the support jaw when adapting the chuck jaw to a changed chucking diameter of the workpiece to be chucked is dispensed with. <IMAGE>

Title: Method and device for monitoring a safety cut-off in internal combustion engines
Inventor: BERGER JOACHIM DIPL ING
IPC: F02D41/22
Filed: 1988-03-12
Abstract: In the method for monitoring a (redundant) safety cut-off in the form of a solenoid cut-off valve (ELAB) in internal combustion engines, that is in particular diesel engines, it is proposed whenever the starting quantity release is given during a starting sequence to shut off (switch off the current to) the safety cut-off valve and to determine whether injections nevertheless occur. This test sequence is performed during a very brief period (1 to 2 secs) during the starting sequence and allows it to be established whether injections nevertheless occur when the safety cut-off valve is switched off. In this case the safety valve is defective and the internal combustion engine can be shut down in the event of further selected safety-related faults. <IMAGE>
