Abstract: A remote controllable toy including a plurality of passive toy units, a plurality of transmitters for remotely controlling the passive toy units, and synchronizing signal transmitting means for transmitting a synchronizing signal to the passive toy units and the transmitters. Each of the transmitters of the passive toy units transmits a control signal for controlling the corresponding passive toy unit when identifying a transmission timing allocated thereto by referring to the synchronizing signal. Each of the passive toy units receives both the synchronizing signal and the control signal, and identifies the timing allocated thereto by referring to the received synchronizing signal, so that it is actuated in accordance with the control signal received within the timing allocated thereto.

Abstract: An ignition system comprising a metal plate having a pyrogen on one side thereof, a turning shaft journalled by the plate, and a sparking wheel secured to the shaft. A flint is supported by the plate and pressed against the wheel. An opening is formed in the plate adjacent the wheel, and a screen is formed on the plate adjacent the opening. The screen deflects sparks through the opening to the pyrogen, and the screen is preferably angled to efficiently deflect the sparks. The igniter is mounted in a self-heating container for heating food or a liquid.
