[Classes 97 (ii) and 97 (iii).] Angular adjustment of a dividing-engine or surveying instrument is effected by a tangential screw engaging circumferential worm gearing on a circular plate, the threads on the screw and worm gearing being of V-section and the bearing of the screw having a groove of V- section adapted to receive a flange of corresponding section on the screw and prevent axial movement of the latter. In the transit shown, the telescope brackets 20 are mounted on a plate 171 having a depending flange 17 and a spindle 13 which is mounted in a socket in a circular plate 10. The latter is supported by spindle 9 in a socket 8 in a member 5 fixed to the levelling head 1. Secured to the flange 17 is a housing 26 containing a screw 27 adapted to engage worm gearing 24 on the plate 10. The screw 27 extends through an elongated aperture 29 which permits it to be withdrawn from gearing 10 against the action of spring 40 by rotation of a transverse screw 38 or by a cam. The inner surface of the bearing aperture 29 has a V-shaped groove 30 and the screw 27 has an outwardly extending co-operating V-shaped flange 31 so that the screw 27 when moved into engaging position is restrained from axial movement. A knurled wheel 33 and a graduated disc 42 co-operating with a fixed index 45 are carried at the end of screw 27. Graduations 23 on the plate 10 are viewed through a window 48. The telescope is rotated about the trunnion 22 and the plate 10 rotated relatively to the member 5 by similar adjusting mechanisms.

IPC: G05F1/20
Filed: 1971-09-08
Abstract: 1317509 Automatic voltage regulation ROBERT BOSCH FERNSEHANLAGEN GmbH 8 Sept 1971 [8 Sept 19701 41906/71 Heading G3X [Also in Division H2] A circuit for compensating the voltage drop along a cable 6 comprises a transformer 9 having secondary windings 12, 13 each provided with tappings 14-16, 17-19, a switching circuit 27 for selectively connecting different pairs of tappings and a control circuit 28 for selecting which pair of tappings are to be connected in dependence on the length of a core 31 of the cable. The primary winding 11 of the transformer is connected to a mains voltage supply UN and the cable 6 is connected to a transformer 38 which may supply, for example, a television camera. A constant current source 32 feeds the core 31 and the circuit 28 includes three Schmitt triggers, the output of which control pairs of the switches 21-26 which are preferably triacs. Since the voltage developed along the core 31 depends on the length of the cable, the particular Schmitt trigger and therefore the particular pair of triacs which are switched on depend on the length of the cable. Thus as the length of the cable and therefore the voltage drops along it increases, the output of the transformer 9 increases to compensate this effect.
