Patent DE-3113478-A1 (DE)
Title: Switched-mode power supply for producing at least one DC-isolated output DC voltage
Inventor: HORSTKOTTE RAINER
IPC: H02H7/12
Filed: 1981-04-03
Abstract: In the primary circuit of a transformer (6) which is connected to at least one switching stage, a switched-mode power supply contains a winding (9) of an inductor (8) whose inductance defines a maximum rate of rise for the current after the switched-mode power supply has been switched on. Furthermore, at least one second inductor winding (10) is connected in series with a rectifier (11) in the primary circuit, in parallel with the series circuit formed by the transformer primary winding of the switching stage (7) and the first inductor winding, or with a secondary winding as well as the rectifier. As a result of the limited current rise, no unacceptably high currents can occur in the switching stage in the event of a short-circuit or overload, despite delay times in the reaction to the short-circuit or the overload. <IMAGE>

Title: Method for producing patterned skirt cuts
Inventor: KLEBER KURT
IPC: A41H3/08
Filed: 1981-04-10
Abstract: Method for producing a material cut, bounded in a circular manner in the hem and waistband region and intended for a woman's skirt which opens out in the manner of a bell, having a parallel stripe or rectangular check pattern which runs essentially at right angles and parallel to the skirt waistband and hem in the finished skirt. The desired progression of the pattern is achieved by virtue of the fact that a piece of unprinted material is printed by screen printing in a region bounded in accordance with the shape of the cut, the pattern region being divided into a multiplicity of gusset-shaped regions which adjoin one another and in which the printing pattern is aligned in the desired manner between skirt waistband and hem. By cutting out the printed pattern region from the material, the skirt cut which can be used to form a woman's skirt is obtained.

Title: Method and circuit arrangement for interference signal suppression where frequency-modulated receivers are used
Inventor: ANDRETZKY WALDEMAR DIPL ING
IPC: H03G3/34
Filed: 1981-08-12
Abstract: A method is proposed having a circuit arrangement for interference signal suppression where frequency-modulated receivers are used, which method is suitable for suppressing all AF signals which occur as a result of interference in the demodulator wherever FM transmission is employed and for through-connecting the AF amplifier only when a frequency-modulated carrier is received. This goal is achieved in that a bistable switch, which is assigned to a combined circuit arrangement for identifying the useful signal and the interference signal, is switched over, when a useful signal pulse occurs from the circuit arrangement for useful signal identification, into the position which through-connects the signal path of the receiver and, when a interference signal has been identified, is switched from the circuit arrangement for interference signal identification into the position which blocks the signal path. <IMAGE>

Title: Process for producing wall elements, and wall element which is produced by the process and is intended for the construction of prefabricated buildings
IPC: E04C2/34
Filed: 1981-08-17
Abstract: Process for the simplified and less expensive production of wall elements which are improved in terms of their precision and quality, are intended for the construction of prefabricated buildings and are formed by the sandwich construction method from two panels, produced from wood cement, and webs, connecting the panels and adhesively bonded to the panels, as well as, if appropriate, filler in the spaces enclosed by the panels and webs. For this purpose, the use of unfinished wood-cement panels as starting material is provided. It is furthermore provided that, by trimming the unfinished panels to the width of the elements by sawing or milling, the unfinished panels are continuously copy-milled on one side, in the region of the border and intermediate webs to be bonded in, and starting from one unfinished side, to a predetermined thickness which is kept within narrow tolerances. After this, once adhesive has been applied on those surfaces of the panels to be adhesively bonded, webs of two panels, with their milled reliefs facing one another, are adhesively bonded to the webs inserted therebetween by exerting a transversely applied pressure. The wood-cement panels of the wall elements accordingly have milled reliefs, which reduce the wall elements to a uniform thickness dimension, in the region of the webs. <IMAGE>

Title: Process for the control of discharge gates of casting vessels for metallurgical castings, and device usable for such a process for the exact position indication of a working piston
Inventor: HANNES HEINZ DIETER
IPC: B22D41/24
Filed: 1982-03-30
Abstract: A process is described for the control of discharge gates of casting vessels for metallurgical castings in dependence on the change in the bath melt level in the casting vessel, the said level being intermittently determined and set, making use of the value of the bath level present at the respective casting instant above the discharge gate, with the melt volume determined from the time integral of the previous respective actual gate openings. The control reference values are compared with at least one bath level boundary value measurement point which directly succeeds the casting stream, and a movement of the discharge gate is initiated on exceeding the boundary value measurement points. According to the invention, in a continuous casting plant with a casting ladle, intermediate casting ladle and continuous casting mould, both the movement of the casting ladle gate and also the movement of the intermediate casting ladle gate are respectively controlled stepwise from their own control systems of like construction. For optimum control, a feedback from the bath level of the mould or from the control of the intermediate casting ladle gate is undertaken for the control of the casting ladle gate. <IMAGE>
