50.~ Load device temperature-modifying means combined with or forming circuit impedance means


DEFINITION

Classification: 315/50

(under subclass 32) Subject matter, wherein the load device is provided with means for heating and/or cooling at least part of the load device structure, such means being either combined with, or forming an electrical impedance element.

(1) Note. In many of the patents in this subclass, the conduit for supplying cooling fluid to the load device is coiled and forms an inductive impedance element.

(2) Note. Mere electrical heaters which are used only to heat the load device and which are not used as impedances in any circuit other than the heater circuit are not included in this subclass.

46, and indented subclasses, for discharge device loads having an electrical heater structurally combined with the discharge device and connected in electrical shunt to the discharge electrodes.

49, for discharge device loads having an electrical heater structurally combined with the discharge device and connected in electrical series with the discharge electrodes.

112, for other systems under the class definition wherein the load device is provided with temperature modifying means. SEE OR SEARCH CLASS
