Patent DE-4309842-C1 (DE)
Title: IC circuit board testing system - uses comparison impedances obtained across test pins for fault-free circuit board during learning phase
Inventor: ARNOLD HARALD ALEXANDER ALFONS
IPC: G01R31/28
Filed: 1993-03-26
Granted: 1994-06-16
Abstract: The testing system for a circuit board carrying a number of ICs and associated components uses a number of test pins contacting respective test points. During a learning phase, a fault-free circuit board is contacted and the impedances between the adjacent test pins are loaded in a memory for comparison with the corresponding values obtained for the tested circuit board. The impedances are also compared with the measured impedances between the test pins when the associated leads are disconnected. Pref. the voltages for each pair of test pins are also compared for the fault-free circuit board and the tested circuit board. ADVANTAGE - Fully-automated testing of complex circuit.

Title: Circuit arrangement for detecting the duration of current flow at converter valves
Inventor: WEGENER KLAUS DIPL ING
IPC: H02M5/27
Filed: 1993-09-22
Granted: 1994-09-29
Abstract: In the case of a circuit arrangement for detecting the duration of current flow at converter valves of two line-commutated converter bridges which are operated free of circulating current in antiparallel connection, signals (SO1, SO2, SO3 and, respectively, SU1, SU2, SU3) are detected for each bridge half which indicate a voltage across the converter valves there. Current-carrying states are reported with a time delay because of a necessary RC attenuation of the converter valves. In order to prevent this delay, the signals (SO1, SO2, SO3 and, respectively, SU1, SU2, SU3) are fed to a NAND element (1) which is connected to two AND elements (3). The aggregate signal (S60 DEG ) of all the trigger pulses is fed to a monostable multivibrator (2), the output signal (S'60 DEG ) of which is applied directly to one of the AND elements (4), and the negated output signal <IMAGE> of which is likewise connected to the NAND element (1). The two AND elements (3, 4) are connected to an OR element (5). The output signal (SO and SU, respectively) of the latter, which signal corresponds to the current flow to be detected, is fed back to the other AND element (3). <IMAGE>

Abstract: A securing device restrains a locking lever 15 which acts on a latch 10 pivoted about axis 11. A first securing lever 13 comprises one arm of an armature 18 pivoted about axis 19 by an electromagnet 12. The lever 13 has a nose 22 which projects parallel to the pivot axis 16 of lever 15 and engages an oppositely directed projection 27 on the lever 15 in a locking position. A second securing lever 23 is pivoted at 8 on the first lever 13 and is provided with a stop 24 to engage lever 15. The second securing lever 23 is spring-biased towards the lever 15 and, on the first securing lever being moved downwards into a release position, reacts against the upper edge 26 of the lever 15 to move upwards against the bias. The two securing levers therefore move in opposite directions to release from lever 15. <IMAGE>
