Abstract

453,584. Switching-systems for lamps. BOSENBERG, H., 4, Alsterufer, Hamburg, Germany. Dec. 7, 1934, No. 35151. Void [Abridged as open to inspection under Sect. 91 of the Acts, June 8, 1935]. Drawings to Specification. [Class 38 (iv)] Illumination of roads, canals or waterways is effected by lamps in groups or sections arranged to be switched on by the passage of the vehicle and to be switched off after a predetermined time or in response to the operation of lamps in a succeeding group or section. The lamps may be switched on by a light sensitive relay responsive to light or shadow produced by the vehicle or by any other suitable means. Switching off is effected by a clock switch or a preceding section is switched off on the switching on of the section succeeding that in which the vehicle is moving. The control may be disabled by a local hand switch to provide illumination when the vehicle is stationary in a section. The road may be illuminated in two halves along its length so that illumination is produced of only that half in which the vehicle is moving.
