Abstract: The invention relates to a dividing table for arranging a clamping device or a workpiece for machining in selectable angular positions. The dividing table has a locating disc (3), a perforated disc (12) connected to the locating disc (3) in such a way as to be locked against rotation, and a rotary drive (8) for the locating disc (3) and the perforated disc (12). Bores (14) are provided in the perforated disc (12). The bores (14) together with the bolts (18) allocated to them form a preindexing device. In addition to this preindexing device, there is a precision indexing device which consists of a longitudinally displaceable precision indexing bolt (21) and one precision indexing bore (17) each allocated to each bore (14) of the preindexing device. The precision indexing bolt (21) can be inserted into the precision indexing bore (17) when the preindexing bolt (18) is located in the corresponding preindexing bore (14). Furthermore, a friction brake (9) is provided by means of which the locating disc (3) and the perforated disc (12) can be connected to the housing (1) in such a way as to be locked against rotation. <IMAGE>

Title: Method for enhancing interference suppression (interference rejection, noise rejection)
Inventor: KROEKEL DIETER DR
IPC: H03K17/94
Filed: 1993-09-07
Abstract: The invention relates to a method and to a device for enhancing interference suppression, in particular in optical proximity switches, with the aid of an optical transmitter emitting an optical pulse train (1), with the aid of an optical receiver outputting a measurement signal (2), and with the aid of a control and evaluation unit which controls the optical transmitter and evaluates the measurement signal (2). In the method, the measurement signal (2) of the optical receiver consists of the superimposition of a continuously output interference background (4) and a measurement pulse (6) output upon the reception of an optical pulse (5), and the measurement signal (2) of the optical receiver is evaluated by the control and evaluation unit in a signal interval (8) during a measurement pulse (6) and in at least one background interval (9) outside the measurement pulse (6). The enhancement of the interference suppression is guaranteed by virtue of the fact that the evaluation is interrupted by spacing intervals (11, 12) before and after the signal intervals or the background intervals (9). <IMAGE>

Title: Hazard warning flashing system for motor vehicles
Inventor: MASLANKA STEPHAN DIPL ING
IPC: B60Q1/52
Filed: 1993-11-01
Abstract: Conventional hazard warning flashing systems on motor vehicles permit all the flashing lights on the vehicle to flash at the same time, in which case, if one side of the vehicle is concealed, the hazard warning flashing system cannot be distinguished from the flashing of the direction indicators. If the hazard warning flashing system of the vehicle flashes with another sequence which is clearly different from the normal 1:1 = on:off sequence or with different colours or with different levels of brightness, any road user knows that this is a hazard warning flashing system even if one half of the vehicle is concealed. When conventional hazard warning flashing systems are switched on, vehicles which are towing or being towed cannot indicate a change in the direction of travel. The hazard warning flashing system described above permits this however by one side flashing normally to indicate turning (1:1 = on:off) while the other side continues to flash as a hazard warning flashing system in accordance with the described characterisation.

Title: Hinge articulation formation
Inventor: DUX JUERGEN
IPC: E05D15/50
Filed: 1994-07-29
Abstract: Known devices for pivoting an element towards two opposed sides, in particular for doors, exhibit a considerable degree of structural outlay. These devices are also unsuitable for horizontal use. This hinge articulation formation is intended, with a simple structural design, to make it possible for an element to pivot alternately vertically and horizontally. Arranged in two opposite pivot axes (A), (B) are at least in each case two hinge articulations (2), (3)/(4), (5), said articulations, which are positioned such that they converge with respect to one another, being respectively connected to one another via an articulation leg (6), (7). The respective second articulation leg (8), (9) of the articulations of one pivot axis are fastened contrarily on the element (1) or body (10) on which the respective second articulation legs (11), (12) of the articulations of the other pivot axis are fastened, these being fastened on the body and on the element in an alternating manner. This hinge articulation formation, which can be extended as required, makes it possible for an element, installed horizontally or vertically, to be pivoted towards two sides. <IMAGE>
