International Classification:

A63H 19/32
E01B 7/00

US Classification:

246415 A, 246415 R

Abstract:

A model railroad track system including first, second and third portions of model railroad track, and a movable portion of track that is movable between a first and a second position. When the movable portion is in the first position the movable portion is configured to guide a model train from the first portion of track to the second portion of track when the train moves across the movable portion in a direction of travel. When the movable portion is in the second position the movable portion is configured to guide a train from the first portion of track to the third portion of track when the train moves across the movable portion generally in the direction of travel. The system further includes an actuator movable between first and second positions, and wherein the distance between the first and second positions of the actuator constitutes a stroke length. The system also includes a switch adapter operatively coupling the actuator to the movable portion of track such that movement of the actuator from the first to the second position causes the movable portion to move from its first to its second position, wherein the distance moved by the movable portion upon the movement of the actuator differs from the stroke length.

International Classification:

H04B 1500

US Classification:

455 62

Abstract:

A remote control system for use with model aircraft provides a user with the capability of placing the remote control system into a scanning mode wherein a receiver scans through a plurality of channels having a predetermined frequency bandwidth and frequency interference detection circuitry is activated upon detection of interference picked up by the receiver on a channel within the selected bandwidth. Warning circuitry is provided to communicate with the frequency interference detection circuitry for providing a warning signal to a user that interference has been detected. A clear channel is then selected and tuning circuitry permits locking of the receiver and the transmitter on the clear channel so that a user can control the flight of a model aircraft by sending rf signals from the transmitter to the receiver.
