Patent DE-3930772-A1 (DE)
Inventor: FRIES HELMUT
IPC: H01R13/193
Filed: 1989-09-14
Abstract: An electric connector includes two complementary connector members, one of which has spring contacts as contact elements and the other has blade contacts as contact elements, wherein the contact elements are mounted in a row or in several parallel rows on base members. The base members are mounted on frame-like enclosing members of housings which extend parallel to the direction of insertion of the contact elements and which serve for the mutual guidance of the housings during the insertion. In the joined state of the connector members, the spring contacts and the corresponding blade contacts can be placed in contact with each other and out of contact from each other by means of contact slide members which are displaceable along the row or rows of contact elements. The connector members can be positively coupled transversely of the direction of insertion by means of locking slide members. The contact slide members and the locking slide members are mounted on the same connector member and are in engagement with a common swivel lever mounted on the same connector member. The engagement between the contact members and the locking slide members is such that, during the coupling procedure as well as during the uncoupling procedure, initially only the locking slide members are movable and the contact slide members are movable subsequently.

Title: Printing machine ink application method
Inventor: ARNOLD WOLFGANG DR
IPC: B41F33/00
Filed: 1989-12-11
Abstract: Printing ink is applied zonally and the effect of material faults, colour variations, cracks, bumps, depressions etc. are recognised and compensated. An average value is obtained for 100 percent and zero percent coverage by measuring the coverage of several oarts of suitable gauge strips of the printed medium or printing plate within given tolerance zones for the white and black zones. These are compared with values measured by sensors within the printed region. The measured values which are stored separately and which correspond to less than zero percent coverage and greater than 100 percent coverage and these divergent values are exchanged for initially obtained values for the following zonal coverage so that the coverage values for less than zero percent are replaced by the average values for zero percentage coverage, and the measured values for less than 100 percent coverage are replaced by the average values for 100 percent coverage.

Patent DE-4013694-A1 (DE)
Inventor: KOBLITZ RUDOLF DR
IPC: H03L7/10
Filed: 1990-04-28
Abstract: PLL control circuits in horizontal oscillators, when locked, must have a low control rate so that, for example, no jitter is generated by noisy input signals. Owing to the infavourable scanning ratio between the synchronising pulse length and the line duration (4.7:64), however, the control rate at greater phase differences in the PLL input signals is low and, e.g. when a television receiver is switched over between different programme sources, it takes a relatively long time (a few half-images) for the line synchronisation to become locked again. By logically assessing an additional pulse already available or easily generated in the television receiver, the control signal for the VCO in the PLL may be switched over at greater phase deviations, e.g. to a fourfold  control current. For PLL control with input signals which do not have a pulse-duty factor ratio of 50:50.
