Patent DE-3502368-A1 (DE)
Inventor: FRINGS ADAM DIPL ING
IPC: B23K31/00
Filed: 1985-01-25
Abstract: A process for the butt-welding of especially deep-drawable steel sheets or steel strips galvanized at least on one side, in which the welding seam is protected against corrosion. To obtain a welding seam flush with the sheet and protected against corrosion, without the reworking of the welding seam and without the use of filler material, sheets or strips having essentially rectangular cut edges with a corrosion in the longitudinal direction of at most 0.4 mm are used. The sheets and strips brought into touch contact with these cut edges are melted in the region of the welding joint by means of a laser beam, of which the focal spot covering the cut edges has a diameter of at most 0.2 mm. Because of the extremely narrow welding gap, the voids are filled by the molten material of the adjacent sheets, without any detectable reduction in the thickness of the sheets or strips. Furthermore, the welding seam is protected against corrosion as a result of the long-range protection effect exerted by the zinc of the adjacent regions.
Patent DE-3508773-A1 (DE)
Title: Method for the phase-compatible switching-on, -off and -over of halfwaves or periods of alternating currents which are intended for the coding and transmission of information, particularly for telecommunication systems
Inventor: DIRR JOSEF DIPL ING
IPC: H03M5/12
Filed: 1985-03-12
Abstract: When alternating currents are used for coding digital signals, it is required to carry out a switching-on, -off or -over of the alternating current, particularly at 0/360 degrees and at 180 degrees. Without accurate switching-over, distortion occurs at the transmitting point and also due to settling processes in the line. The invention avoids these disadvantages in that synchronisation pulses are generated directly or indirectly by the respective alternating coding current, with which synchronisation pulses an electronic switch is accurately controlled at 0/360 and at 180 degrees and thus carries out the respective switching task.

Title: Circuit arrangement of a switching stage amplifier
Inventor: NESTLER JOHANNES DR ING
IPC: H03F3/217
Filed: 1985-12-20
Abstract: In a switching stage amplifier which consists of the series circuit of a number of amplifier stages which mainly operate as switching amplifiers (2...n) and, in a low number, also as linear amplifiers (1), the circuit complexity is to be kept down. For this purpose, the individual stages are constructed as an asymmetric bridge circuit with two semiconductor switches and two diodes, fed from a constant-voltage direct-voltage source (E1, E2...En). When operating as switching amplifiers, the semiconductor switches consist of gate turn-off thyristors and, when operated as linear amplifiers, of power transistors. The circuit arrangement can be advantageously used as active filter in supplying particle accelerators with magnetic current or as semiconductor modulation amplifiers in transmitters. <IMAGE>
Patent DE-3600143-A1 (DE)
Inventor: BALD WILFRIED
IPC: B21B45/06
Filed: 1986-01-07
Abstract: The rolling mill for mechanical descaling of hot rolled steel is constructed according to the slidable roll process with reducing rolls so that a unform operation with different and/or changing shape steel strips can obtained. This is attained when the rolling mill has at least two rolls slidable in opposite directions whose body surfaces are constructed with S-shape contours positioned inversely to each other so that these contours compliment each other flawlessly in one certain axial relative position. When sliding the rolls in opposite directions in one case the contour is decreased in the center region of the steel strip and when slid in the opposite directions in the other case the contour is increased in the center region. Thus the rolls can be adjusted to fit a gently convex steel strip profile by axially sliding the rolls in opposite directions as also rolled strips with a thickness centrally reduced in comparison to that of the edge regions can by appropriate sliding of the rolls opposite each other.

Title: Middle container with swivel door systems for forming large transporting units and continuous-access large-size units
Inventor: REMMERT WERNER
IPC: B65D88/12
Filed: 1986-01-09
Abstract: A middle container, whose broad sides preferably consist of horizontally divided swivel doors, form a large transporting unit together with other middle containers - placed one after the other on or in a standardised transporting vessel or vehicle - and, when the swivel doors are swivelled inwards, form a continuous-access large-size loading unit. When the middle containers have been filled and the swivel doors have been closed - one middle container after another - these form an independent, transferable loading and freight unit. The middle container which can be moved on rollers is developed for use in the sphere of unit loads for dispatchers, haulage companies and the federal railway as a universal storage and transporting vessel, high requirements being placed on its versatility in use and its rationalisation possibilities in the sector of unit loads, e.g.:   - compatibility with standardised conveying aids, such as pallets, both in the interior itself and in loading in the transporting vessel; - use for short-distance and long-distance transportation and in combined traffic for the federal railway and haulage companies;   - movable by crane and stackable.   The dimensions of the middle container are 2.40 m (width), 1.40 m (depth), 2.00 m (height).
Patent DE-3603828-A1 (DE)
Title: Method for the automatic printing of horizontal and vertical lines in a definition region in the form of a rectangle in a word-processing system
Inventor: BRANDES RONALD DIPL ING
IPC: B41J29/28
Filed: 1986-02-07
Abstract: In known word-processing systems, the input of vertical and horizontal lines for preparing tables is very awkward, the storage of the data taking up a lot of space. According to the invention, this method is simplified in that a dot is positioned on the paper by moving the printing mechanism and the roller, at which point the left upper corner of a desired definition region is marked by a special first code function key and is stored in a register memory (21) for storing the coordinates of the left upper corner, then the printing mechanism (11) is positioned at the desired right lower corner of the definition region and, by means of a special second code function key (18), the calculation of the difference between the coordinates of the left upper corner and of the right lower corner is initiated. After the left upper corner and the right lower corner have been defined, the printing of the tables or forms can be initiated, for which purpose only very few key actuations are required. The definition region can also be enlarged or made narrower as desired by changing the position of the right lower corner of the definition region. <IMAGE>
Patent DE-3604771-A1 (DE)
Title: Fluid friction clutch
Inventor: SCHAEFER ARNOLD
IPC: F16D35/00
Filed: 1986-02-14
Abstract: A description is given of a fluid friction clutch, particularly for motor-vehicle differentials. The fluid friction clutch (1) allows automatic adjustment of the distance between the individual plates (18, 19). This is accomplished by means of a radial wall (7a) which divides the annular chamber of the fluid friction clutch (1) into two subchambers (12, 13). The two chambers (12, 13) are connected to one another via a hole (14). Due to the different surface areas of the radial wall, the viscous fluid contained in the annular chamber gives rise to a resultant force which urges the plate carrier (7) in the direction of the plates (18, 19). An increase in the transmissible torque is thereby achieved. The plate carrier (7) can be stopped by suitable means (pins 20) or a stop plate (22). This is desirable in certain driving conditions, e.g. during braking. <IMAGE>

Title: Device for fixing a reduction ring on a shaft for a solid-stock forming press
Inventor: PETZ UWE DIPL ING
IPC: B21J13/08
Filed: 1986-05-21
Abstract: The invention relates to a device for fixing a reduction ring (5) on a shaft (1) for a solid-stock (massive) forming press with a mounting ring (3) which is rigidly mounted on the shaft (1) - rotationally fixed in the rest condition - and on which the reduction ring (5) is mounted in a manner secure against rotation, and with means for preventing the axial displacement of the reduction ring (5) on the mounting ring (3). To reduce the installation, setting and changeover times, two clamping jaws (32, 33) are mounted on the mounting ring (3) in a manner which allows them to be moved in the radial direction. In an end part remote from the reduction ring (5) and extending into the central region of the device, each clamping jaw (32, 33) cooperates with an eccentric cam region (13, 14) of an eccentric shaft (12) to give a positive outward movement towards the reduction ring (5) and a positive movement away from the reduction ring (5), and the eccentric shaft (12) is mounted coaxially to the shaft (1) and can be actuated manually by means of handle components (30) to produce a rotary motion. <IMAGE>
