Abstract: ROUTE INTERLOCKING CONTROL SYSTEM                ABSTRACT OF THE DISCLOSURE     A single relay serves to register route request selections for both traffic directions over each track route through a railroad interlocking layout.  This single route request relay is jointly controlled by the route selection push buttons for both directions, the actuated push button being also repeated by a traffic direction relay.  The route request relay pick up checks that no conflicting route request is active, and that the same or opposing route is not already established and locked.  The route request and direction repeater relays are held by stick circuits to store the request until the route is locked.  A single relay serves to provide the clear and lock function for all possible traffic routes originating at each entry point into the interlocking.  Each clear and lock relay responds to the registry of a route request originating at that location but also checks, in accordance with the route switch positions, that the opposing approach lock relay is still picked up, that the involved track sections within the interlocking are unoccupied, and the absence of cab signal energy for an opposing train within the interlocking.  The clear/lock relay selects and enables the clearing of the correct route entry signal, releases the route request storage, and locks the established route against any opposing route request.  Cancellation of a route request or a locked route with cleared signal is provided, with separate actions as the approach track is or is not occupied.  Cancellation of a locked route and cleared signal requires the usual time delay to assure that an approaching train stops short before a con-flicting move is authorized.

Abstract: ANIMATED DITHERED DISPLAY SYSTEMS            Abstract of the Disclosure Dithered display systems are adapted to present animated images via a conditional replenishment technique.          The only cells of the display panel which are accessed for any given frame are cells which are to have states in that frame which differ from their respective states in the previous frame.  Additionally, random scintillations in animated dithered displays are substantially eliminated by establishing a hysteresis band about the dither threshold value assigned to each display cell.  The hysteresis band is delimited by upper and lower dither threshold values.          Determination of whether the intensity of a given picture element of the image to be displayed is to be compared to the upper or the lower dither threshold value assigned to the corresponding display cell is made based on the current state of the cell.

Abstract: REFLECTIVE LENS SYSTEM             ABSTRACT A tacheometer utilizes a gallium arsenide laser diode in a phase shifting distance encoder, a sinusoidal interpolator in a phase shifting shaft angle encoder, a mercury pool in a phase shifting two axis off-level encoder, a shared phase to digital decoder and a digital processor, to measure angles and distances corrected for off-level, speed of light variations, refraction and the earth's curvature.  A reflecting telescope is coupled to the shaft angle encoder and is incorporated in both the phase shifting distance encoder and the alignment system.  The reflecting telescope has a doublet objective lens with an embedded secondary reflective surface facing a primary mangin mirror.          A biconcave element of the doublet objective lens also functions as a corrector for the secondary reflective surface.         A compact objective lens system is thus realized, having mini-mal interference between the corrector for the secondary reflective surface and the optical path through the doublet objective lens.

A relatively thin annular band of semiconductive paint is disposed between terminals of the fuse apparatus on the inner surface of the enclosure. The enclosure is made primarily of insulating material.  When the fuse blows, the voltage difference between the opposite ends of the fuse is capacitively coupled through the enclosure to the indicator.          The indicator is sensitive to a change in voltage there-across and periodically illuminates to indicate that the fuse within has blown.
