Patent DE-4033684-A1 (DE)
Inventor: UEKOETTER ANTON
IPC: E05B47/00
Filed: 1990-10-23
Abstract: The electromotively driven door lock comprises a latch (11), driveable manually by a pushbutton (23), and a bolt (35) which can be driven both by itself and together with the latch (11) from an electric motor (43) via a gear (45) and a control part (47) displaceable transversely to the direction of displacement of the bolt. In order, if necessary, also to have the possibility of moving the bolt (35) inwards manually together with the latch (11), the pushbutton (23) is coupled via a rack (87) to a pivotable take-up part (199) which takes up a tenon (103) of the control part (47) in the opening direction via a take-up finger (101). The radii of the toothings (85, 97) of the pushbutton (23) and of the take-up part (99) which mesh with the rack (87) are calculated so that a rotary-angle step-up is obtained. This allows a compact design of the door lock, suitable especially as a tubular-frame lock, without necessitating an increase in the power of the electric motor (43). <IMAGE>

Title: Evaluating analogue voltage signals for controlling IC engine of motor vehicle - using circuit contg. A=D converter, reference voltage source and computer
Inventor: MEICHER JOACHIM
IPC: G01R19/257
Filed: 1990-11-10
Abstract: The reference voltage source (8) provides a predetermined stipulated voltage for the a-d converter (5).
