Abstract
418,831. Electric signalling systems. WHINCUP, C. H., Tower Picture House, New Briggate, Leeds. May 2, 1933, No. 12714. [Class 40 (i).] In a system for signalling the available seating accommodation in a theatre or the like of the type wherein information may be transmitted from various sections of the auditorium to the office, provision is made for return-way enquiry and communication. As shown, the various sections F, G, H of the auditorium are provided with switches A, 1, 2 ; B, 1, 2 ; C<2>, 1, 2 &c. for operating lamps c in a display panel in the office P. The lamps circuits are controlled by relays A, B, C &c. which lock up when operated. The back contacts of the relays are interconnected in such a manner that when one relay is operated, operation of the other relays is prevented. The relays also may be operated by switches provided in the office the relays being provided with further contacts for operating signal lamps e located at the various sections of the auditorium. Moreover when any one station is signalling, lamps ware lit at the non-signalling stations over interconnected contacts of the relays. The system may be reset to normal by operation of any one of the cancelling switches CS. The lamps c are contained in a compartmented casing having a front of transparent material bearing opaque characters.
