A device for rotating motor vehicle headlamps to a raised or retracted position comprises electrically operated interlocks which hold the lamps in their required position but which are energizable upon actuation of a lamp control lever to release the lamps for rotation to their other position. Each interlock comprises an electromagnet coil 37 and an armature 35 which carries a plunger 33 for movement into or out of engagement with a notched disc 30 connected adjacent to one headlamp to rotate with the lamp. When the lamp is to be moved from one position to another the lamp control lever, (20) Fig. 3, not shown, is operated and contacts (70, 72) of a switch built into the lever are automatically made so that current flows in the coil 37 to retract the armature 35 and remove the plunger 33 from notch 31 in the disc 30, allowing free rotation of the lamp. Further operation of the control lever rotates the lamp via the rack and pinion 12, 13 and presents the other notch 31 to the plunger 33. Release of the control lever breaks the contacts (70, 72) and the plunger 33 is forced by a spring 40 into the new notch 31 guided by link 52 to retain the lamp in its new position. Rod 10 interconnects the headlamps of the vehicle for simultaneous operation. In the case where the movement of the lamps is carried out by a vacuum motor the vacuum motor is controlled by the same switch as the interlock.

Filed: 1961-11-27
Abstract: 943,568. Exciting dynamo electric machines. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 31, 1962 [Nov. 27, 1961], No. 42341/61. Heading H2A. The exciting flux of an A.C. or D.C. machine is made to vary linearly through a range of positive and negative valves by using a circuit arrangement comprising two full-wave rectifiers 12, 13, supplying main field winding 11 in shunt and two series connected auxiliary field windings 16. The rectifier bridges are connected to pass opposing currents through the main field and comprise controlled rectifiers 15. In operation, one rectifier bridge 13 is kept non-conductive while the other 12 supplies the exciting current, when this is reduced nearly to zero rectifier 13 starts to conduct. When the output voltage is zero the currents supplied by the rectifiers are equal and opposite so there is no current in winding 11 and the fluxes produced by the series windings cancel to give zero flux in the machine. As more negative voltage is required, rectifier 13 supplies more current and rectifier 12 becomes progressively non-conductive to give the linear characteristic as shown in Fig. 5. The series fields 16 may comprise only a small number of turns, sufficient to limit the circulating current to a safe value.
