Abstract

403,720. Road signals for controlling traffic. AUTOMATIC ELECTRIC CO., Ltd., Strowger Works, and RENSHAW, P. B., Brookwood, Alder Road, West Derby, both in Liverpool. June 30, 1932, No. 18548. Drawings to Specification. [Class 118 (ii).] In a system in which a number of control signals are regulated from a master controller, each of the controlled units has individual control equipment which affects the signals at a slower rate than the rate of the master controller so that the individual units only effect complete control when the master equipment is not in use. Certain movements of the equipment are normally locally controlled to ensure that the signals are shewing for a predetermined minimum time if faults in the equipment should maintain the signal relays in operated condition. The master controller regulates the controlled units at different times in its cycle to maintain the phase relationship required with the progressive type of traffic control systems and emergency controls are provided for putting all the signals at all or any of the controlled units at danger and for placing a unit under manual control. The description is identical with part of the description in Specification 403,732. Specifications 356,102 and 403,731 also are referred to.
