(under subclass 86) Systems, having in addition subject matter as defined in subclass 88 and the notes thereto.
(1) Note. In many of the systems in this subclass, the first operated source of electrical energy is connected to the first operated load device or electrode, the automatically operating means being operative to connect the second operated source of electrical energy to the second operated load device to thereby substitute a different source of electric energy and a different load device for the first operated source of energy and load device. The respective sources of supply and load devices or electrodes may constitute separate circuits except for the control of the substituted circuit in response to the condition of the first operated circuit.
