Abstract: A device for indicating a certain proximity between movable units emitting to the units a synchronizing signal with a very high transmission speed. A transmitter device is situated at least on certain of the units. The transmitter device is activated by the synchronizing pulse to emit an information signal in the form of a wave propagation movement in the medium in which the units are located. The wave propagation movement has in comparison with the synchronizing signal a considerably lower transmission speed. In at least certain others of the units the information signal is received by and related to the difference in time between the synchronizing signal and the received information signal to a predetermined time value corresponding to a certain proximity between the units. Thereafter the difference in time is evaluated in relation to the predetermined time value.

Abstract: A detector circuit for a model railroad employs two pairs of magnetically-operated relays positioned on either side of a grade crossing along a set of tracks. In addition a single magnetically-operated relay is located at the grade crossing and is given an orientation orthogonal to that of the two pairs of relays. A locomotive of the model railroad is equipped with a first magnet for operating the pairs of relays and at least one car has a second magnet for operating the relay at the grade crossing. A control circuit is connected to the relays such that crossing gates at the grade crossing are lowered, a bell is sounded, and lights are flashed whenever the locomotive magnet passes over the pairs of relays traveling toward the grade crossing. The control circuit also raises the crossing gate and deactivates the bell and flashing lights whenever the car magnet moves over the relay at the grade crossing or the locomotive magnet moves over one of the pairs of relays while traveling away from the grade crossing.

Abstract: An apparatus for detecting the presence and/or direction and/or velocity of a moving ferromagnetic element is provided. A sensing coil is placed in coupling relationship with a bi-stable ferromagnetic wire to provide a signal in response to a change in polarity of the core of the bi-stable wire. The core polarity changes in response to element presence as the element constitutes a magnetic shunt causing a change in magnetic flux density and/or direction in the air gap of a magnetic circuit in which the bi-stable wire is situated. The sensor is substantially insensitive to element velocity. Modified structures provide for fail-safe operation.

Abstract: A communication system for track or guideway operated vehicles is disclosed. The system is adapted for two-way transmission between a vehicle and a wayside station and is provided with a transmission line of special configuration along the wayside. The transmission line comprises three conductors each having a wave configuration with the waves disposed in three-phase relationship and a return conductor which is also of wave configuration. The vehicle transmitter section is provided with an inductive loop which is coupled with the transmission line and is energized with a continuous wave signal. This produces signals on the three phase conductors which have an envelope frequency proportional to vehicle speed and a phase relationship corresponding to the relative position of the wave configurations of the phase conductors. Thus, vehicle speed may be derived by measuring frequency and vehicle position may be derived by counting cycles or pulses from a given starting point. Direction of the vehicle travel can be derived from the phase sequence of the signals in the phase conductors. At the base station, the receiver section is provided with means for squaring each of the phase signals and summing the squared signals to develop a continuous signal, i.e. one which has an amplitude independent of the position of the transmitting loop along the transmission line. The two way voice communication channel and a two way data communication channel is also provided utilizing the above mentioned transmission line. The transmission line configuration and the configuration of the transmitting and receiving loops are such that the system is immune to far field radiation.
