Abstract: A ceramic heating rate regulator for electrically powered thermal treatment operations is described. The regulator is made of a ceramic mixture containing molybdenum disilicide, which is an electrically conductive substance undergoing crystal structure transformation above 700.degree. C. The regulator comprises an elongated ceramic rod containing high concentration of molybdenum disilicide, the rod is subsequently insulated by a ceramic cylinder which contains silicon nitride and low concentrations of molybdenum disilicide. The regulator when incorporated in the heating circuit of the thermal treatment furnace will itself heat up and thus reduce the size of the heating current flowing in the circuit, as soon as the temperature of the regulator has reached the transformation temperature of molybdenum disilicide. The heating rate regulator is designed to be used in conjunction with conventional temperature controlling devices.

Abstract: An electrical energy storage device for storing electrical energy and supplying the electrical energy to a driving motor at different power levels is disclosed. The electrical storage device has an energy battery connected to a power battery. The energy battery has a higher energy density than the power battery. However, the power battery can provide electrical power to the electrical motor at different power rates, thereby ensuring that the motor has sufficient power and current when needed. The power battery can be recharged by the energy storage battery. In this way, the power battery temporarily stores electrical energy received from the energy battery and both batteries can provide electrical energy at the different power rates as required by the motor. The energy storage device can be releasably connected to an external power source in order to recharge both batteries. Both batteries can be recharged independently to optimize the recharging and lifetime characteristics of the batteries.
