Abstract: An electromechanical system for generating heat in metallic vessels, includes a vessel which acts as a load resistance for the secondary of a transformer having a very low voltage and a high current. The voltage developed in the secondary of the transformer is applied directly to the vessel between two diametrically opposed areas comprising contact members on the vessel. Electrodes are engaged to press against the contact members and the electrodes are connected to the terminals of the secondary of the transformer. The system includes a mechanism for controlling the distance between the electrodes for separating the electrodes from the contact members on the vessel in order to remove or place the vessel between the electrodes and for moving the electrodes closer together with strong pressure against the contact members on the vessel for closing the electric circuit of the secondary.
