DEFINITION

Classification: 315/227

(under the class definition) Systems provided with a condenser connected either in electrical series relation or electrical shunt relation to the load device and the source of current supply for the load device.

(1) Note. This subclass includes systems having a condenser and discharge device, the condenser being charged by a suitable source of potential until the potential is sufficient to ionize the discharge space of the discharge device, when the condenser is discharged through the discharge device. Such systems are included whether the system is stated to be for the production of oscillations or merely for the production of the space discharge (light generation). In some of the systems, the condenser is connected so as to form, with the other circuit elements, an oscillatory circuit. Such oscillatory circuit systems are included even though it is not clear from the patent that the discharge gas is ionized with each oscillatory impulse of current. Where it is clear that the oscillatory circuit is merely fed with current through the discharge device, and the oscillatory current does not ionize the discharge space but continues to oscillate in a closed circuit which does not include the discharge device, the oscillatory circuit is considered as a load device and the patent is excluded from this class, and will be found in Class 331, Oscillators, particularly subclasses 126+ for electrical oscillator systems of the gaseous space discharge device type utilizing a capacitor as one of the frequency determining elements of the system, indented subclass 128 providing for systems wherein the gaseous space discharge device provides for shock-excitation of an LC circuit, subclasses 143+ for relaxation oscillator utilizing space discharge devices and wherein an RC time constant network determines the period or frequency of the generated oscillation and subclasses 165+ for oscillators in general comprising a shock-excited resonant circuit or some related class.
