Abstract
1408763 Visible signalling apparatus TIDELAND SIGNAL CORP 30 Oct 1972 [23 Dec 1971] 25773/74 Divided out of 1408761 Heading G4F The subject-matter is contained within the Specification 1408761, but the claims are concerned with a navigational light comprising a timer 14, lamp-changing mechanism 26, 28 and a failed lamp sensing circuit 24, the latter including switching means for actuating the lampchanging mechanism, a first electrical connection (e.g. a diode), between the timer output and switching means to prevent actuation of the mechanism during the duratien of a timing signal, and a second electrical connection (e.g. a diode), through, a lamp filament to a power supply to prevent actuation of the switching means when the filament is out.
