The invention relates to a mounting support (1) for phototransmitters (10) and photoreceivers (11) to be arranged in the way of forked light barriers, between which the rim portion of a signal disk (28) is capable of being moved. On the mounting support (1) there are provided insertion openings (8, 9) for inserting the phototransmitters (10) and the photoreceivers (11). These are provided with a locking element with which the inserted phototransmitter (10) or the inserted photoreceiver (11) can be locked and thus definitely fixed in their positions. No other adjustments are required.

Mounting support for several phototransmitters and photoreceivers

In a pulse generator with a rotor (7) provided with a conductive pattern and fixed contact springs wiping over the pattern, the latter is formed by a central continuous slip ring (15) which is concentric with the drive shaft (3) of the rotor (7) and has inwardly and outwardly projecting teeth (16; 17), the number of internal teeth (16) being equal to the number of external teeth (17), and the internal and external teeth having the same angular spacing (.alpha.). A fixed contact (32) slides on the slip ring, and two fixed impulse contacts (33, 31) slide on circular paths (K1, K2) formed by the internal teeth (16) and the external teeth (17), respectively, and the internal teeth (16) are staggered with respect to the external teeth (17) and/or the two fixed impulse contacts (31, 33) are displaced in relation to one another such that at least in one direction of rotation of the rotor (7), the fixed impulse contacts (31, 33) cannot simultaneously make contact with a tooth (16, 17) of their circular paths (K1, K2) or with the flank of such a tooth.

Pulse generator

In a signal generator with a magnetic rest, consisting of a ferromagnetic studded disk (13) with a U-shaped part (6) consisting of a permanent magnet (3) and lateral ferromagnetic small plates (4,5), two brackets (7, 8) are provided for on a support (1) between which the permanent magnet (3) and the small plates (4, 5) are capable of being clampingly inserted. This permits an easy assembly and adjustment of the permanent magnet (3) as well as of the small plates (4, 5).

Signal generator

An electrical connector having an insulator with semicircular recesses therein for receiving sheetmetal contacts. In the assembled condition, the contacts are applied with their broad sides to the straight inside wall of the recess while the cutting edges of the contacts are pressed into the curved inside wall of the recess. In this way the contact strips can be inserted in an oriented direction.
