Patent DE-3113039-A1 (DE)
Title: Operating-regulation circuit having a current regulator for radiating diodes
Inventor: FREULING MARTIN
IPC: H01S5/062
Filed: 1981-04-01
Abstract: In the case of an operation-regulating circuit having a current regulator for producing a control current which controls the radiation power of a radiating diode in accordance with signals, it is intended to ensure the regulation even when the radiation intensity is not yet sufficient, or is no longer sufficient, to operate a photodiode, which is the case, for example, in the case of a laser radiating diode in the luminescent-radiation band. The invention achieves this object in that, before the action of a power control loop, there is additionally a control loop which is operated by a constant current and acts in each case when, and only when, the current is still below the operating point required for the power control loop to operate, or falls below this operating point in the course of regulation, and which control loop is connected to the power control loop via a cut-out diode.

Title: Device for closing a garage up-and-over door
Inventor: ESTHER HERMANN
IPC: E05C17/04
Filed: 1981-07-30
Abstract: The invention relates to a device for closing a garage up-and-over door having manual locking. It is known that wet motor vehicles parked in closed garages rust more rapidly than motor vehicles regularly parked in the open. The invention is intended to eliminate this disadvantage by a closing of the garage up-and-over door not in the conventional vertical position sealing off the air, but in an oblique position which leaves a free passage for the drying air open in the lower region. The simple mechanism required for this is characterised merely by a pivoting shackle which is articulated on the garage floor near the front edge and on the free end of which an engagement orifice for the end piece of the locking rod is provided.
Patent DE-3136245-A1 (DE)
Title: Tool-carrier arrangement on a tooth-flank grinding machine
Inventor: ULRICH HANS-JOACHIM DIPL ING
IPC: B23F23/12
Filed: 1981-09-12
Abstract: The invention relates to a tool-carrier arrangement on a tooth-flank grinding machine which works according to the single-indexing method, in which the rotating grinding body is moved stroke-like in a rectilinear manner and the grinding spindle is arranged in a grinding-spindle slide with guide elements for an additional movement with an operative component at right angles to the stroke direction. The invention is to increase the working accuracy and the working productivity of the tooth-flank grinding machine by virtue of the fact that a tool-carrier arrangement of high static and dynamic rigidity is created and interference movements at the interfaces at the engagement point between workpiece and tool can only be effective in a greatly weakened form. According to the invention, this is achieved by the grinding-spindle slide being designed as a spindle head which encloses the grinding body in a supporting manner, and guide elements are arranged on both sides at the grinding-spindle slide in such a way that both the grinding body and the grinding-spindle axis lie between them. Furthermore, the grinding-spindle slide is arranged inside the stroke slide, the grinding-spindle slide and stroke slide are connected to one another in a positive-locking manner in the stroke direction, and the grinding-spindle slide is displaceable at right angles to the stroke direction in the stroke slide. The dressing device is attached inside the stroke slide. <IMAGE>

Title: Arrangement for data and voice transmission and for location of vehicles
Inventor: DJAMSHIDPOUR MASSOUD DIPL ING
IPC: B61L25/02
Filed: 1981-10-07
Abstract: For an arrangement for data and voice transmission between a route-fixed station and route-bound vehicles, in particular a maglev railway and similar vehicles, by means of a line conductor laid along the route and comprising outgoing and return conductors, and ferrite antennas fitted to the vehicles, and for locating the vehicles by crossing the outgoing and return conductors at specific intervals, the object is to design the arrangement with a reduction in received interference, an increase in line conductor currents and simpler installation of the line conductors. The object is achieved by laying the outgoing and return conductors (1, 2) of the line conductor in one plane (E) running vertically in relation to the centre of the ferrite antenna (3) and by separating them from one another by a distance (bs) which is greater by a factor of one to three than the distance (h) between the upper conductor and the ferrite antenna axis (bs = (1...3) . h), and the distance (h) is dependent on the mechanical characteristics of the application concerned and is selected to be as small as possible. A special application is in maglev railways. <IMAGE>

IPC: B01D65/00
Filed: 1981-11-03
Abstract: A diffusion device and/or filter having an apparatus (4c) for conducting the flow of fluids in a box-shaped housing is provided with selectively permeable membrane sections (7), which are stacked in the housing (4a, 4b, 4c), each of the edges of the membrane sections (7) assigned to a housing wall (4c) forms a component of influent orifices (12) for a fluid conducted over parts of the membrane surfaces and the influent edges form a common plane (9) with the influent orifices (12). The spaced-apart housing wall (4c) forms an influent and distribution chamber (10), this being provided with a multiplicity of sheet ribs (32) running roughly in parallel to each other on the side facing the influent orifices (12) and influent edges in the plane of the stack (9). The sheet channels (31) running between the sheet ribs (32) of the housing wall (4c) merge into a common inlet channel (30) of a housing inlet (3a). In a stack of flat membrane sections (7), the sheet ribs (32) and sheet channels (31) are arranged at right angles to the direction of layering of the membranes (7). The inlet channel (30) runs approximately at right angles to the sheet channels (31) and the entries to the sheet channels (31) are provided with bends in the direction of the inlet (3a). The sheet ribs (32) form a sawtooth profile in cross-section, whose pointed ridge lies on the top surface (9) of the fold package. The influent fluid is thereby divided into a multiplicity of part streams, so that short-circuit pathways and preferred flow pathways are avoided. <IMAGE>

Patent DE-3150291-A1 (DE)
Title: Process for re-using dusts formed in stainless steel production
Inventor: FUHRMANN HEINZ JOERG DIPL ING
IPC: C22B7/02
Filed: 1981-12-18
Abstract: The invention provides for the re-use of dusts formed in stainless steel production and having correspondingly high contents of valuable alloy elements. The dusts are first turned into lumps in a known manner, water and/or binder as well as carbon being added to them in a more than stoichiometric proportion. The lumps are then treated in the crude steel melt of an electric induction furnace at more than 1600 DEG C until a reduction of the metal oxides to their metals has taken place. Above all, this leads to the reduction of chromium and nickel. The molten alloyed-up steel can then be recycled as alloy element carrier to the stainless steel production.

Patent DE-3205478-A1 (DE)
Inventor: GROBECKER HERMANN
IPC: B65D85/57
Filed: 1982-02-16
Abstract: High storage density information carriers, particularly optically readable video discs and digital records, can only be read error-free by a playback device when the high requirements made of freedom from warping also remain guaranteed over long storage times. A cassette is provided to support and fix an information carrier only within its central portion which is free of information tracks and, by a sufficient spacing of the information carrier in the support-free area between a bottom portion and a cover portion contact with the information carrier in this area is avoided, even given consideration of maximally-admissible warping tolerances of the storage cassette and of the information carrier.
Patent DE-3214601-A1 (DE)
Title: Cassette holder for an X-ray examination unit
Inventor: RAUCH WERNER ING GRAD
IPC: G03B42/02
Filed: 1982-04-20
Abstract: The invention relates to a cassette holder for an X-ray examination unit, such as is used in order to hold X-ray film cassettes directly at the body of a patient. Cassette holders which are capable of holding X-ray film cassettes of different sizes generally have the disadvantage that they are adapted to the largest possible X-ray film cassette and when holding smaller X-ray film cassettes impede the application thereof as a consequence of their own larger dimensions. In this regard, the invention provides that a plurality of cassette frames (1), which accommodate one X-ray film cassette (34) in each case, can be individually mounted on a coding frame (2) of the X-ray examination unit, which coding frame is coupled to switching elements (64) and supports sensors (51-61) which scan the cassette format. In addition, each cassette frame can be designed for in each case only a single discrete cassette format and can carry coding perforations (14-33), which characterise the cassette format, on its side that can be mounted on the coding frame. The cassette holder according to the invention is particularly suitable for use on X-ray examination units. <IMAGE>
Patent DE-3215629-A1 (DE)
Title: Electronic circuit for the actuators of a two-position or three-position control system
Inventor: KOLLMANN ECKHARD DR ING
IPC: G05B11/28
Filed: 1982-04-27
Abstract: This circuit exhibits a counter. The counter is cyclically activated by a computer calculating the control process and the count is reduced down to zero by a counting clock whereupon the actuating signal is switched. A sign signal transmitted by the computer at the same time as the count determines whether the actuating signal is switched on or off during the counting process. This makes it possible to effect the switching-on of the actuating signal at other times than the cycle times in deviation from the prior art.

Patent DE-3217091-A1 (DE)
Title: Process for partially alloying rotationally symmetrical castings
Inventor: CASPERS KARL-HEINZ ING GRAD
IPC: B22D27/00
Filed: 1982-05-07
Abstract: The invention relates to a process for partially alloying rotationally symmetrical castings. For this purpose, in particular for use on cast iron melts, a partial quantity of cast iron melt is first cast into a centrifugal casting die, and an alloy partner - for example tin for cylinder liners - is then directly introduced into the casting stream of the residual melt. Thus a structural composition suited to the respectively desired properties is achieved on the inside and outside of the casting. For cylinder liners for internal combustion engines, tin is added to the residual melt via the casting stream, leading to outstanding running properties. An additional effect of the process is the saving in scarce and expensive alloy partners.

Filed: 1982-06-08
Abstract: The invention relates to a drive for functional groups in sheet-feeding cylinders of perfecting machines which can be used selectively for perfecting or first impression, and in which the sheet is turned by the principle of trailing edge turning. The object of designing a drive for functional groups in such a way that, in the arrangement inside the sheet-feeding cylinder, the cams are not subject to restrictions, caused by the diameter of the sheet-feeding cylinder, in their geometrical, kinematic and dynamic dimensioning, is achieved in that the cam connected to the gearwheel is arranged with rotary movement centrally relative to the axis of the sheet-feeding cylinder.
Patent DE-3223401-A1 (DE)
Title: Heat-treatment channel
IPC: D02J13/00
Filed: 1982-06-23
Abstract: The heat-treatment channel serves essentially for the thermosetting of high-strength industrial yarns which are held tensioned in the longitudinal direction and which run longitudinally through the channel in a large number parallel and next to one another. Electrical radiant heating serves for heating the yarns. The cast nonferrous metal plates are arranged close to one another in the transverse direction, whereas in the longitudinal direction they are arranged at a distance from one another in order to produce an air-passage slit transversely over the working width. The transverse air passing through the yarns here from the bottom upwards is generated by means of fans arranged on the longitudinal side of the channel. The transverse air can be heated by external heating, but preferably likewise by the radiant heating which heats not only the yarns, but also the surrounding walls. <IMAGE>
