Abstract: In the case of a hinge having a body hinge part which can be preassembled on a body and a door hinge part which can be preassembled on a door leaf, wherein the hinge parts are connected to each other in an articulated manner, provision is made for the body and door hinge parts to have respective flange parts fastenable onto a surface, and a height- and depth-adjusting device is arranged in the body flange part and has at least one first fastening element which can be used to fix the set height and depth position of the door leaf in relation to the body.

Abstract: A lock system has a lock cylinder pivotal about an axis between a pair of end positions and through a center starting position, a key fittable into the cylinder and actuatable to pivot the cylinder between its positions, an arcuate magnet centered on the axis and coupled to the cylinder for joint movement therewith, and a pair of angularly spaced Hall-effect sensors adjacent the magnet, trippable by the magnet to generate respective outputs, and positioned such that in the central position the magnet is closely juxtaposed with and trips both sensors, in one of the end positions the magnet is closely juxtaposed with and trips only one of the sensors and is spaced from the other of the sensors, and in the other end position the magnet is closely juxtaposed with and trips only the other sensor and is spaced from the one sensor.

Abstract: A motor-vehicle door-latch system has a key cylinder pivotal about an axis from a center starting position into a pair of opposite end positions flanking the center position, a key insertable into the cylinder only in the starting position thereof, a latch operable by the cylinder on displacement of same into one of the end positions, and an arcuate magnet pivotal about the axis, polarized generally parallel to the axis, and coupled to the cylinder for joint angular movement therewith. A pair of hall-effect sensors are juxtaposed with the magnet and positioned such that in the central position the magnet is closely juxtaposed with both sensors, in the one end position the magnet is closely juxtaposed with one of the sensors and is spaced from the other of the sensors, and in the other end position the magnet is closely juxtaposed with the other sensor and is spaced from the one sensor.
