ANTICIPATING THERMOSTATIC TRANSMITTER
First Claim
1. An anticipating thermostatic transmitter for connection in a series circuit with a power supply and a receiver, said transmitter comprising a temperature deformable element, said element having a mounted end and a free end, a first contact movable by the free end, a second contact in a predetermined position and engagable by said first contact, a first conductor and a second conductor for connecting the transmitter into said series circuit, deflecting means coupled between the conductors and energizable therefrom to deflect said element, a controllable switching device controlling energization of the deflecting means and completing said series circuit, and trigger voltage supply means coupled between said conductors and controllable by said contacts for selectively closing the switching device.

Abstract
A controllable switching device closes and opens a series circuit comprising a power supply and a receiver. The switching device is controlled by an on-off thermostat responsive to both the ambient temperature and an anticipating heater, the energization and deenergization of which is controlled by the switching device. The result of use of such an anticipating thermostatic transmitter is the production of an on-off time proportioned current in the series circuit.
