Title: Circuit arrangement for measuring and damping asymmetrical radio interference voltage on symmetrical two-wire connection lines of telecommunications devices
Inventor: WALTER DIETER
IPC: H04M3/30
Filed: 1982-02-19
Abstract: In a circuit arrangement (SM) for measuring and damping asymmetrical radio interference voltage on symmetrical two-wire connection lines of telecommunications equipment (FG), the transmission of the user data signal is not to be significantly impaired, while at the same time the radio interference voltage is to be attributed to the corresponding interference source. For this purpose, a highly symmetrical choke (D1) with an extended mid-point is inserted according to the invention between the two wires (a, b), which choke is connected to one pole of a measuring device (MG), while a winding of a current-compensated choke (D2) is inserted in each case in each of the two wires (a, b) in the line section facing away from the device under test. <IMAGE>

Title: Lock cylinder for a motor-vehicle lock
Inventor: NONNEMANN HERBERT DR ING
IPC: E05B17/00
Filed: 1982-04-23
Abstract: The invention relates to a lock cylinder for a motor-vehicle lock, having radially arranged tumbler pins and a rotor which bears with a head against an annular shoulder of the stator bore and has, on its outwardly pointing end face, a spring-loaded dust cap covering a key-insertion orifice and in the rotor head of which a downwardly pointing drainage channel is present, and in the stator wall surrounding the latter a further downwardly pointing drainage channel being provided. An annular groove is cut out from the rotor head, and the stator is provided with an annular groove as a counterpart to this. The clear cross-sections thus complete one another to form a continuous annular channel. This prevents water which has penetrated into the lock cylinder from being trapped as a result of the close fits between the rotor-head circumference and the stator.

Patent DE-3228777-A1 (DE)
Title: Swing door
Inventor: WANZL RUDOLF
IPC: E05F15/614
Filed: 1982-08-02
Abstract: In hitherto known swing doors, inadmissible deviations in position of the gear parts relative to one another have occurred as a result of welding distortion. Moreover, various parts carrying the drive mechanism have been guided from the outside of the shell of the swing doors produced from round tubing to the inside. The outwardly visible screw heads have adversely affected the aesthetic appearance of swing doors produced from chrome steel. The swing door (1) according to the inventions avoids these disadvantages, in that the connection of the upper housing (3) to the gear housing (33) or to the lower housing (2) is formed releasably by vertically arranged screwing means, and a carrier piece (20), carrying both the electric motor (6) and the drive mechanism (17), is connected by vertically arranged screwing means to at least one support (22) which is fastened in the lower housing (2). <IMAGE>

Additionally, the stand of the holding device is simultaneously the stand for an additional table top for drinks, valuables or the like. <IMAGE>
Patent DE-3232348-A1 (DE)
Inventor: LEUTHOLD KARL
IPC: B65H29/40
Filed: 1982-08-31
Abstract: A device for stacking sheets comprises several disks arranged adjacent to each other on a driving shaft, the disks having spiral slots running from the outside towards the inside. The spiral slots of the disks overlap in an axial direction and together form a pocket into which the sheets conveyed. In order to guarantee trouble-free stacking of the sheets, the spiral slots of adjacent disks are staggered at least in the inner area of the stacker. Therefore, almost all the kinetic energy of a sheet which is inserted into the shot is issipated by frictional and flexing. The spiral slots of one or more disks may additionally be provided with elastic boundary walls.

IPC: C21C7/00
Filed: 1982-10-19
Abstract: The invention relates to a method for the addition of a grain refiner in wire or rod form to a metal melt for casting, such as an Al alloy bath. The refiner should be added rapidly and precisely in a defined quantity with simple method steps, if required with the use of a device of simple construction, and achieve a saving in terms of refiner as compared to grain refining with the aid of pigs and furthermore increase the grain refining effect. To achieve this object, the wire or rod containing the grain refiner is cut precisely to the length which corresponds to the quantity of refiner to be added and the piece of wire or rod is plunged into the standing metal melt in a casting or holding crucible with a reciprocating or helical motion.

Inventor: WENZEL GUENTER
IPC: H01H50/02
Filed: 1983-02-22
Abstract: In this electromagnetic relay, pegs which are associated with a coil, switch contacts and an angle-shaped yoke are soldered to a printed-circuit board. Supported on the free limb of the angle-shaped yoke is an armature which can be attracted to a core, which passes through the coil, of the yoke. Arranged on at least one narrow side of the rectangular-shaped printed-circuit board are conductor parts which run tangentially with respect to the coil and at right angles to the longitudinal axis of the core, and are electrically connected to the pegs via conductor tracks. At the other end, the conductor parts are connected to circular-cylindrical plug pegs which are mounted at mutually fixed distances on a rectangular plug board for engagement in plug sockets of a commercially-available plug holder. The rectangular plug board is arranged at a distance parallel to the printed-circuit board. The yoke, with the coil and the armature, is located between the two boards.

Title: Structural panel, in particular gypsum plasterboard
Inventor: LUETJE HARALD
IPC: E04C2/04
Filed: 1983-09-16
Abstract: In the case of structural panels for the purposes of insulation or for cladding walls, etc., it is known to fasten a water bar in the region of the joint between adjacent panels and subsequently to fill in said bar with gypsum. This entails considerable labour because the water bar must first of all be fastened and the jointing work can only then be carried out. In order to remedy this, a structural panel, which has already been prefabricated, is provided according to the invention with a water bar along an edge strip at one end side, a part of which joint taped can be spread out along a folding line and laid on an edge strip of the adjacent structural panel. The jointing work is then carried out. The complex and costly labour operation to fasten the water barred to the structural panel when installing said structural panels is thus dispensed with.

Title: Photolithographic device and magnetic surface memories produced thereby
Inventor: ELSNER GERHARD DIPL PHYS DR
IPC: G02B5/32
Filed: 1984-02-10
Abstract: In order to generate large-area, periodic patterns, the substrates (9) covered with a photosensitive layer are brought into the interference field (8) which is produced by four plane, mutually inclined waves. The plane waves are produced by splitting a laser beam (1) in a holographic lattice grating (2) which directs the total incident light energy into the four first diffraction orders. In order to collimate the diffraction beam, use is preferably made of large-area mirror optical systems by means of which the angle of inclination of the plane waves with respect to one another can be varied. It is possible to produce with the aid of the photolithographic device magnetic surface memories having vertical, insular magnetisation domains, or other surfaces which are covered with closely packed, vertical needles. <IMAGE>
