Patent DE-3620858-A1 (DE)
Inventor: RAMSAY JOHN ROBERT
IPC: G11C7/10
Filed: 1986-06-21
Abstract: A circuit for use in conjunction with a microprocessor for refreshing, checking and correcting data signals stored in a dynamic memory. The circuit utilizes a direct memory access controller for transferring data signals stored in successive locations of the dynamic memory to a non-existent peripheral. Data signals appearing on a data bus as a result of the data transfer, are applied to a parity checking circuit for generating an interrupt signal to the microprocessor in response to detection of parity errors in the data signal. The microprocessor then performs a data recovery routine in which correct versions of the data signal stored in a non-volatile memory, are transferred for storage in the dynamic memory under control of a microprocessor. Parity errors in data signals stored in the dynamic memory are thus corrected prior to being accessed by the microprocessor.
Patent DE-3626966-A1 (DE)
Inventor: JORDAN ULRICH
IPC: B23H9/08
Filed: 1986-08-08
Abstract: In a process for electrochemically machining workpieces, in particular for galvanising, sharpening or oxidizing the same, a flow of electrolyte from an electrode (2) is directed against the edge or surface of the workpiece (8) to be machined in such a way that the impact of the flow of electrolyte on the workpiece is punctual or linear. Once the electrode and the workpiece have been connected to a voltage source, the electrode is moved relative to the workpiece or vice-versa, thus allowing the edge or surface to be electrochemically machined. The device for carrying out this process has a voltage source and an electric circuit which connects the voltage source with the electrode and the workpiece. The electrode is shaped as a split electrode and has a feeding device for the electrolyte, a first electrically conductive electrode section connected with the voltage source and a second split electrode section. A conveying device (3) moves the split electrode relative to the workpiece, or the workpiece relative to the split electrode.

Inventor: LATARIUS HANS
IPC: G05D23/19
Filed: 1986-09-17
Abstract: Integrated in the housing (1) of the storage heater in addition to the storage core (5) and the blower (6) circulating air from the room through the storage core are measuring and controlling components required for room temperature control. A first temperature sensor (T1) is arranged at a point in the interior of the housing remote from the storage core (5) in such a way that it is influenced by the room temperature. A second temperature sensor (T2) is arranged away from the first temperature sensor (T1) in the housing (1) in such a way that it is influenced primarily by the temperature of the storage core. Both temperature sensors are incorporated in a correcting device, which generates from the signals derived from the temperature sensors a signal representing the room temperature actual value, for a comparison with the set value, which controls at least the switching on of the blower (6). A third temperature sensor (T3) is arranged in the blower air stream and assumes control of the room temperature when the blower is switched on. <IMAGE>

Title: Method for computer-assisted three-dimensional video body measurement
Inventor: KREYENBERG KLAUS
IPC: G01B11/25
Filed: 1986-11-11
Abstract: In previously known methods, the measurement was carried out by optical measurement using a raster wall as a reference plate, the measurement having been carried out by means of a line grating projected from a certain angle. However, such a known method has the disadvantage that the recording of photos produced by double exposure is cumbersome and time-consuming and no automation is possible. The invention is based on the object of creating an improved method for body measuring, by means of which the disadvantages of previously known methods can be avoided. The object is achieved by a method which is characterised by combining the method steps of projecting lines on a body by means of a projector and the method step of recording the body with the lines by means of a video camera, which inputs the image for automatic analysis into a computer in which a reference raster already exists as program component.

Title: Profile-dressing device for double-cone abrasive wheels
Inventor: SOBCZYK REINHARD DIPL ING
IPC: B23F23/12
Filed: 1987-05-08
Abstract: Profile-dressing device for double-cone abrasive wheels on tooth-profile grinding machines, in the case of which device, in addition to a dressing device with which in each case the end face and the circumferential faces of the double-cone abrasive wheel can be dressed, a form-dressing tool is present, with which a profile can be produced between end face and circumferential face. The aim is to produce gears with higher transmission power. The object is to create a profile on the double-cone abrasive wheel with low technical outlay, short dressing times and with a high degree of accuracy. According to the invention, this is achieved in that the form-dressing tool 4 is firmly connected to the dressing device 1 and can be adjusted, together with the latter, radially with respect to the double-cone abrasive wheel 5. The form-dressing tool 4 is arranged in a position III between dressing position I of the dressing device 1 and working position IV of the double-cone abrasive wheel 5. The speed course of the grinding-spindle bearing 8, on which the double-cone abrasive wheel 5 is arranged, can be varied by means of signal transmitters 9; 10, which are connected to a drive 11 of the grinding-spindle bearing 8, from the change-over position II to the position III of the form-dressing tool 4. <IMAGE>

Title: Transformer
Inventor: LUTZ FERDINAND DR
IPC: H01F27/28
Filed: 1987-09-25
Abstract: In the case of transformers, in oder to reduce the cost for insulating the coils from the transformer core at high voltages, transformers are used in a cascade circuit with a plurality of interconnected individual transformers. Transformers in a cascade circuit of the known type require a considerably higher cost for the windings. Since the individual transformers each have to transmit different powers, cost-effective unification, which would enable economical manufacture, of these individual transformers and their windings is not possible. In contrast, the new transformer in a cascade circuit enables unification of the individual transformers and of their windings. The novel transformer in a cascade circuit consists of subunits [(18)-(25)] each having one [(15), (16) and (17)] or more [(1)-(4), (5)-(7), (8)-(10), (11)-(12) and (13)-(14)] series-connected individual transformers which are wired up in such a manner that all the subunits and all the individual transformers transmit the same power. Transformers for measurement tasks (voltage transformers), for producing high test voltages and for power transmission, especially superconductor transformers as well. <IMAGE>

Patent DE-3737173-A1 (DE)
Title: Controllable shock absorber
Inventor: MUENNING HANS DR ING
IPC: B60G17/044
Filed: 1987-11-03
Abstract: The invention relates to a controllable hydraulic shock absorber which, in parallel with the flow through a damping piston provided with valve openings, has an additional flow-control member, this additional flow-control member being controllable in its damping action by means of a control element. This control is effected by means of a control chamber containing the control element which is acted upon. In order to provide a shock absorber of this kind with the ability for height adjustment, the invention provides, in the case of at least one control chamber, for the said chamber to be connected selectively, by means of a control slide, to one of the working chambers above and below the damping piston. The control element is thus acted upon in the control chamber and controls not only the additional flow-control member but also the valve openings on the same side of the piston, allowing the flow to be closed off direction-dependently to a greater or lesser extent. This allows utilisation of the dynamic damper behaviour during vehicle oscillations to achieve effective level control of the shock absorber.

Title: Process and apparatus for the anaerobic fluidised-bed purification of waste water
IPC: C02F3/28
Filed: 1988-06-11
Abstract: The waste water (effluent) to be purified is passed from bottom to top through a fluidised particle bed in a reactor vessel 1. Here it is desirable if the particle material can be adjusted in specific gravity, can be decreased in specific gravity and has an open-pored surface and the apparatus can be matched to this particle material. This is achieved by using crushed expanded clay as particle material and by furnishing the reactor vessel 1 longitudinally and with a tapering inlet region 2 having an end tube 8, into which fits a rotatable screw 7 above which is provided a non return valve 6. By using crushed expanded clay and the apparatus adapted thereto, improved adaptability to the particular waste water conditions and decreased energy consumption are achieved. <IMAGE>

Title: Group of substances for fixation purposes
Inventor: SCHUBERT WERNER DR MED
IPC: G01N1/28
Filed: 1988-07-01
Abstract: Toxic formalin can be substantially, in some cases completely, replaced in various types of fixation procedures in histology/anatomy/microbiology by tannic acid and/or organic and inorganic substances having a similar action. It is also possible to use a 0.1-0.3% strength tannic acid solution even for the transport of histological material. Even weak solutions of tannic acid have astringent effects whereas, which is unfavourable for microscopic evaluation of histological specimens, the conventional aqueous formalin solutions (for example 1 part of formol in 9 parts of water) usually act to swell cell nuclei and body cells. Tumour assessment can, for example, be facilitated by the tannin fixation.
Patent DE-3826350-A1 (DE)
Title: Ramming device for feeding ammunition which needs to be loaded separately
Inventor: NORDMANN ADOLF
IPC: F41A9/42
Filed: 1988-08-03
Abstract: In the case of known ramming devices for feeding ammunition which needs to be loaded separately into the firing chamber of a large-caliber gun (weapon with a barrel), the ramming lever is driven via an epicyclic gear which is mounted on a support which can pivot. However, such a drive runs into limits resulting from its weight and its space requirements when it is necessary to move the ramming lever over an extremely long and straight movement path. The invention provides a remedy for this by the use of a chain drive or belt drive (14, 15, 16), because the pinion (15) which is required for the pivoting movement of the ramming lever (8) about its axis can be arranged at a large distance from a stationary central axis (12) of a support (9) which holds the pinion (15) and of a stationary pinion (14) which is connected to the pinion (15) via a chain. On one side, the support (9) contains a toothed segment (11) by means of which it can be driven such that it pivots about the stationary axis (12). The chain drive (14, 15, 16) illustrated or a bolt drive which is not illustrated enables gentle feeding as a result of the elasticity of the chain or of the bolt, especially of a propellant charge, from a relatively large distance. <IMAGE>

Title: Process for the pyrolysis of organic wastes
Inventor: NEMETZ HERBERT
IPC: C10B53/00
Filed: 1988-08-22
Abstract: In a process for the pyrolysis of organic wastes, the raw material is charged (1) via a predryer (3), which is as a rule charged batchwise and is heated by the exhaust gases (4) of a thermal engine (15), dried and introduced from the latter into the tower (6.1), usually aligned vertically, of a pyrolyser (6). In the latter, the material (1.1) is deflected into essentially horizontally extending layers of uniform height, width and length and transferred into the adjoining heatable pyrolysis chamber (6.2) while the outlet device (8) is closed and, after uniform filling of the material (1.1) introduced, the inlet device (7) is closed. The heating is effected by electrical heating resistors (16) which are supplied by the current produced by the generator part of the thermal engine (15). <IMAGE>

Title: Method and arrangement to raise the number of information words to be transferred via an interface between two units of a data processing system
Inventor: GLAESER WINFRIED DIPL ING
IPC: G06F9/22
Filed: 1989-01-18
Abstract: The number of information words, e.g. command words, to be transferred via an interface between a first unit, e.g. a command memory (BSP), and a second unit, e.g. a control unit (CW), is raised by converting frequently occurring information words into words of smaller bit width, and then recombining these coded words into a code word with the width of the information words. To distinguish between the coded and uncoded information words, a marker bit is added to the information word. After the transfer, the marker bit is inspected, to determine whether the transferred word consists of several coded information words or only of one uncoded information word. If the transferred word consists of several coded information words, it is separated into the individual coded information words using a multiplexer circuit (DMUX), and the coded information words are used as addresses to read the assigned information word from a decoder circuit (DK). The decoded information word is then processed. By combining coded frequently occurring information words into one word of the width of the information words, several information words can be transferred from one unit to another, by transferring one word via an interface. <IMAGE>

IPC: D06F58/24
Filed: 1989-02-03
Abstract: A laundry dryer (10) has an interior (13) for the reception of laundry and a condenser (40) into which can be introduced on the one hand steam-laden hot air (14) from the interior (13) and on the other hand a cooling medium (15) which are brought into heat-conducting contact in the condenser (40) for the purpose of cooling the air (14). The condenser (40) has a first cavity for guiding the hot air (14), a second cavity for guiding the cooling medium (15) and a heat-conducting intermediate wall separating the cavities over a large area. In order to make it possible that, in relation to the useful interior (13), a laundry dryer (10) with the smallest possible dimensions can be produced by providing a condenser (40) with as small dimensions as possible, the first cavity is, furthermore, brought into heat-conducting contact over a large area, via a heat-conducting outer wall (18; 19; 22) of the laundry dryer (10), with an exterior (17) which surrounds the laundry dryer (10) (Figure 1). <IMAGE>

IPC: C09D5/06
Filed: 1989-02-09
Abstract: An aqueous artist's paint based on a water-soluble saccharide, a natural dye, a filler and optionally other additives is described. This artist's paint is distinguished in that it contains about 5 to 60% by weight of a water-insoluble polysaccharide as the filler. The artist's paint prepared analogously to the prior recipe has a pasty consistency which makes it suitable as a child's paint. It can be applied as a paint by brush or finger. This child's paint is largely made up of natural, renewable constituents, is toxicologically harmless and can be washed out with customary detergents from nearly all textiles, even with cold water. In spite of these outstanding advantageous features, it is to be compared without hesitation, with respect to its paint properties, with conventional aqueous artist's paints for children.

Title: Fluid-operated anti-lock brake system with traction control
Inventor: BECK ERHARD
IPC: B60T8/44
Filed: 1989-03-02
Abstract: A description is given of a brake system which is suitable for regulating both the braking slip and the tractive slip. In order to cover for the run-up phase of the pumps - during which their delivery rate is low - in the case of traction control, an accumulator (42) is connected up. This accumulator must supply a sufficient volume of pressure medium at as constant a level as possible. At the same time, its overall volume should be small. To this end, the proposal is to use a piston-type accumulator whose actuating pressure is produced by the pressure difference between a vacuum source and the atmosphere or a compressor pressure. <IMAGE>
