ABSTRACT:
The apparatus includes a cup having a metal base and seated on an insulating support, beneath which is positioned an electrical coil, by means of which heating currents are induced in the metal base of the cup, and this heat is transferred to the fluid which is in the cup, in contact with the metal base. A control circuit is provided including means for generating the heating currents and for selecting the desired temperature. The circuit includes a thermal sensor in heat transfer relation with the cup and coupled to the circuit which controls the operation of the oscillator and the heating of the fluid in the cup to the desired temperature.
