Patent DE-3222327-A1 (DE)
Title: Vacuum vapour-deposition apparatus
Inventor: GOERNITZ ECKHARD DR RER NAT
IPC: C23C14/30
Filed: 1982-06-14
Abstract: The invention relates to a vacuum vapour-deposition apparatus such as is used, in particular, in plasma-active coating technology. The apparatuses disclosed hitherto not only have a relatively low energy efficiency but also have the disadvantage of a short hollow cathode service life. The object of the invention was not only to improve the two abovementioned parameters substantially, but to reduce the expenditure on electrical supply and to make it possible to continuously regulate the molten spot diameter while achieving clean coatings. The object was achieved by optimising the cathode-anode spacing and by placing a chamber having an opening directed at the anode above the cathode. The special shape of a longitudinal magnetic field coil, which is insulated from the crucible anode, makes it possible to produce a highly concentrated magnetic field and also to regulate the molten spot diameter continuously.

Title: Track-lowering, ballast take-up and edgeway milling-off machine
Inventor: COELLEN HEINRICH
IPC: E01B27/10
Filed: 1982-06-23
Abstract: This invention relates to a movable track-treating machine for treating bed ballast and edgeways, clearing the ballast under the track and a device for delivering and in particular for filling the ballast in the silo into the regions between the sleepers and in front of the sleeper ends, milling off the edgeways and taking up ballast. The ballast take-up device is also at the same time usable as edgeway lowering device. The ballast take-up or the edgeway lowering takes place by means of two milling tools which are arranged at the side of the machine and adjustable independently of one another. The track lowering device consists of two scraper chains which are arranged at the side of the machine and adjustable in height and side independently of one another. The bed ballast is conveyed by means of a conveyor belt (ballast take-up device) into the ballast silo or on a conveyor road. The ballast silo is equipped with a ballast dispensing device. The outlet openings are arranged in such a manner that the sleeper gaps between and outside the rails and in front of the sleeper heads can be filled with ballast. The filling quantities are regulated by a control device.

Title: Method of producing an underpinning
Inventor: FRANK ANTON DIPL ING
IPC: E02D27/48
Filed: 1982-06-25
Abstract: In a method of producing an underpinning, the root piles, after they are erected for supporting a building, are provided with sheathings in the area of the concrete floor to be produced in order to eliminate a frictional connection between the concrete floor and the root piles. After completion of the concrete floor and if need be after regulating settlement of the building, sleeve-like connecting members are produced which firmly enclose the root piles and rest on the surface of the concrete floor. The building loads acting directly on the root piles are transferred to the concrete floor, after which the earth under the concrete floor is excavated and then the root piles are cut off below the concrete floor.

Patent DE-3234603-A1 (DE)
Title: Arrangement for forming a signal proportional to the machine flux of a rotating-field machine
Inventor: HUSSELS PETER DIPL ING
IPC: H02P21/10
Filed: 1982-09-15
Abstract: To control converter-fed rotating-field machines, an electric voltage signal, which is proportional to the machine flux of the rotating-field machine, is needed as actual value of the machine flux in the indirectly flux-oriented method. For this purpose, a circuit arrangement is used in which two-phase measurement values of stator current (i alpha , i beta ) and voltage of the machine (u alpha , u beta ) are rotated back (im, il, um, ul) by the precalculated or estimated position of the flux (cos theta , sin theta ) with the aid of coordinate shifters. The stator flux ( psi sm,  psi sl) is formed from the components of the voltage (Um, Ul) or of current (im, il) and voltage (um, ul) thus determined by component-by-component integration of the voltage signals (um, ul) by means of integrators (I1, I2) which have a frequency-proportional cross-coupled feedback and - either frequency-proportional or non-frequency-proportional - direct-coupled feedback. <IMAGE>

Title: Cone warping machine
Inventor: DERICHS JOSEF DR ING
IPC: D02H3/00
Filed: 1983-01-15
Abstract: To allow an automatic warping operation, without previously having to determine exactly the respective cone angle, the warping support (4) acquires a jib (32) displaceable transversely to its direction of displacement and moving away from the winding axis (31) in accordance with the yarn build-up. Moreover, the warping support (4) acquires a device (34) which interacts with the support drive (5) and which keeps the jib (32) at a predetermined distance from the warping cone (3). The withdrawal of the jib (32) in accordance with the growth of the wound package (22) can take place, for example, by means of a roller (43) bearing against the wound package (22). The device (34) can possess a proximity sensor (38) connected to the jib (32) and directed towards the warping cone. By means of an operative connection (40), a controller (35) belonging to the device (34) can act on the support drive (5) in such a way that the warping support (4) and therefore also the proximity sensor (38) always maintain a predetermined distance from the warping cone (3). <IMAGE>

Abstract: The coil field electrode for a device for medical shortwave therapy consists of a resonant circuit coil (1), which serves the purpose of electromagnetic coupling to the patient, and one or more capacitors (2) which form a resonant circuit in parallel connection to the resonant circuit coil (1). The resonant circuit is run from a generator via a homogeneous line (4), one line pole (4.1) of which is connected to the start of the first coil winding (1.1) and the other line pole (4.2) of which is connected to this winding (1.1), or to one of the next windings, at a point (5) at which the partial impedance of the resonant circuit existing in the event of resonance between said point and the start of the first winding (1.1) is equal to the characteristic impedance of the line (4). The line (4) can be a low-resistance coaxial cable. A phase discriminator (9) connected on the electrode side to the line controls as a function of the phase shift between current and voltage on the line (4) an actuator (6) which controls a tuning capacitor (3) for automatic impedance matching between the line (4) and resonant circuit. <IMAGE>

Title: Apparatus used as an aid for exercises in water and adapted to travel along the flange of the overflow channel of a swimming pool
Inventor: BARTHEL NORBERT DIPL ING
IPC: A63B69/12
Filed: 1983-02-08
Abstract: As a replacement for a gripping bar, which cannot be fitted on a swimming pool with an overflow channel, an apparatus to be used as an aid was developed as a mobile gripping bar system. It comprises an intrinsically stable framework of stainless tubing which, in triangular form (Fig. 3), is composed of two upper booms as gripping bars and, for reasons of reinforcement, of a lower boom, which is connected to the two upper booms by corresponding diagonals (Figs. 1 and 2). The apparatus is placed on each side by two or more plastic rollers onto the flange of the overflow channel of a swimming pool and guided by the said channel in the running direction along the longitudinal sides of the pool. The apparatus thus offers the possibility of a two-sided gripping bar system (Fig. 2) for various exercises in water which is adapted to travel to any desired position of a swimming pool and is located just a few centimetres above the surface of the water. The apparatus weighs about 75 kg and, when not in use, is lifted out of the flange by two persons using grips provided on the two supports and is hung on the wall at the end of the swimming baths. <IMAGE>

Title: Process for producing a thermally insulated cable conduit
Inventor: SCHMIDTCHEN HANS MARTIN DIPL I
IPC: F16L59/02
Filed: 1983-02-17
Abstract: In a process for producing a thermally insulated cable conduit, a plastics strip is formed into a tube concentrically to and at a distance from a metal inner tube and sealed at its strip edges. Before the sealing of the strip edges, a foamable plastics mixture based on polyurethane is applied to the plastics strip, which plastics mixture foam-fills the annular space between the metal tube and the plastics strip formed into the tube. The plastics strip formed into the tube, which is very soft and flexible and accordingly cannot withstand the pressure occurring during foaming, is encased externally during the foaming of the foam layer by a supporting sleeve fed so as to be longitudinally incoming and made of mechanically strong material, which is removed from the finished cable conduit after curing of the foam.

IPC: F01C11/00
Filed: 1983-04-29
Abstract: A rotary-piston machine (10) includes a pot (30) which can rotate with a casing (16) and in which a rotor (12) is mounted in an eccentrically rotatable manner. In the rotor (12) there are piston slide valves (44) arranged in such a way that they can move back and forth in radial slits (18), which valves bear against the cylindrical inner wall of the pot (30) upon rotation of the rotor (12) and seal off from one another working chambers (54) which are formed by the inner wall of the pot (30), by the outer walls of the rotor and by a cover (38) which is connected stationarily at the end face to the casing (16) and in which there is an inlet channel (64) and an outlet channel (70) for a working gas. The rotor (12) contains concave recesses (52) in the region between the slits (18). In the working chambers (54) there are arranged movable segments (56) which have parallel walls (58) towards the cover (38) and towards the side part of the pot (30) and in each case have a wall (62, 60) adapted to the inside wall of the pot and to the concave recess (52). During the rotation of the rotor (12) and of the pot (30) taken along by the rotor (12) by means of the piston slide valves (44), the segments (56) bear against the inside wall of the pot. On account of the eccentric position of the rotor (12), different volumes occur in the working chambers (54) during the rotation. These are utilised to take in, compress and ignite an explosive gas mixture. The explosion causes as part of an increase in volume a relative movement between the ...

Title: Circuit arrangement for DC voltage conversion
Inventor: RUDOLPH RAINER
IPC: H02M3/158
Filed: 1983-05-04
Abstract: A circuit arrangement is proposed for generating a bipolar output voltage from a unipolar input voltage, having a frequency generating stage in which only a single coil (11) is used. The connections of the coil to the unipolar input voltage are periodically interrupted by two switches (S1, S2) which are driven by means of the frequency generating stage (12). The induction voltage which occurs in consequence at the ends (X, Y) of the coil is stored via in each case one diode (13, 16) in two stores (15, 18) which are constructed as capacitors. By means of different stabilisation and regulation arrangements (14, 17), these two voltages (U1, U2), whose mathematical signs are different, can be stabilised against load fluctuations and fluctuations in the unipolar input voltage. <IMAGE>

Title: Isolating chamber
Inventor: PEDREROL JUAN
IPC: G21F7/00
Filed: 1983-05-25
Abstract: The invention relates to an isolating chamber for handling systems which have been contaminated radioactively and/or toxically. When such systems are opened, e.g. because of repairs or maintenance, work is carried out in an isolating chamber (1) which is sealed against the environment, in order precisely to confine the surroundings exposed to the contamination. In order to achieve the highest possible safety, a working cabin (5) is provided which has a multilayer base part (2). The cabin (5) is sealingly connected to the uppermost layer (13a). A first enveloping chamber (14), which is connected to the layer (13b) situated therebelow, ensures that contamination cannot be exported outwards in the event of damage to the actual working cabin (5). Further layers (13c, d, ...) are present in the base part (2) as a precaution, so that if required further enveloping chambers can be erected around the first enveloping chamber, without dismantling the isolating chamber or interrupting its operation. <IMAGE>

Title: Method for reproducing grey scale images on screens of terminals for transmitting two-level scanning signals of image originals
Inventor: MAUERSBERGER WOLFGANG DR ING
IPC: H04N1/32
Filed: 1983-12-10
Abstract: The method according to the invention provides for investigating a received information consisting of two-level scanning signals of image originals, to find out whether grey scale value structures coded in accordance with the ordered-Dither method are present. The Dither structure of each area element is then recoded within a grey scale block in such a manner that a binary value is formed from this structure, in which the number of light or dark pixels per area element are specified. From this binary value, a digital/analog convertor is used to form an analog value by means of which the intensity of the cathode beam at a screen is controlled.
