A three color aspect light signalling system that displays one color at a time without producing phantom signals. The apparatus utilizes three sources of collimated white light, a filter and two dichroic mirror/filters are used to produce three colored aspects and two output lenses are used to collimate the colored output signal so that it may be seen at distances greater than one mile.

Three aspect signalling device using no moving parts

A railway signaling relay for use in vital circuits has a high percentage release (ratio of drop away current to pickup current between 70% and 80%) by arrangement of contact springs and their associated pressure and stop plates which provide trapped pressure in the contact springs affording the high percentage release characteristic without modification of the electrical or basic mechanical configuration of the relay and retaining its vital characteristics.
