Patent DE-3227391-A1 (DE)
Title: Control device for a reversible converter without any loop current
Inventor: BERGMANN LUTZ DIPL ING
IPC: H02M7/757
Filed: 1982-07-22
Abstract: In this control device for a reversible converter which is supplied from a three-phase network, in a reverse-parallel connection of two three-phase bridges, a current direction transmitter (14) without any switching hysteresis is used to initiate reversal of the current direction. The current direction transmitter (14) causes an alternating reversal in the current direction at triple the network frequency in the case of small currents, in order to keep the current controller (3) always ready to react and in order to prevent disturbing dead times and unacceptable current surges during a reversal in the current direction. In order to generate the changeovers at triple the network frequency, the triggering pulses (Z) of the triggering equipment (16) are collected by means of a pulse collector (20) and are supplied to a frequency divider (22) via a pulse extender (21). The frequency divider (22) controls a polarity reverser (11) to which the desired current value (Ides) is applied and whose AC voltage on the output side is added to the desired current value (Ides) and supplied to the current direction transmitter (14). The control device can be used in drive technology for supplying DC motors. <IMAGE>

Patent DE-3247336-A1 (DE)
Title: Cup housing and closure method
Inventor: KLASCHKA RUDOLF
IPC: H05K5/06
Filed: 1982-12-21
Abstract: The invention relates to a prefabricated cup housing, especially for cup-type capacitors, and to a cup housing which is closed by a closure plug, as well as to a closure method which is suitable for this purpose. In the case of known cup housings, especially miniature electrolytic capacitors, it was not possible to subject the closure plug to any excessively large internal pressure stress. The normally known subsequent formation of a rim or indentation of a beading cannot, however, be implemented in the case of a suitable cup housing, especially in terms of aspects relating to mass production with very short assembly times. For this reason, a cup housing having a preformed bead indentation was created which, in terms of the method, is constructed by axial material upsetting to form a retaining bead of the closure plug, the compression and holding forces of the closure plug being further reinforced by the reduction in diameter of the expansion of the cup housing provided in the opening region.
