118.~ Load device circuit controlled by the temperature modifying medium


DEFINITION

Classification: 315/118

(under subclass 112) Systems provided with means controlled by the temperature modifying medium for altering the operation of the load device.

(1) Note. The control exercised over the load device may be to open the circuit of the load device, to regulate the current supply to the load device, or any other control necessary for either the protection or the proper operation of the load device in view of the condition of the temperature modifying medium.

(2) Note. The temperature modifying means may control the load device in response to (1) the temperature of the temperature modifying medium, or (2) the rate of flow of the temperature modifying medium, or (3) any other condition which would affect the operation of the load device.

(3) Note. See note (1) to the definition of subclass 112.

SEE OR SEARCH CLASS

250, Radiant Energy, 429, and 430 for methods and apparatus for subjecting fluent materials to radiant energy rays or emanations, the apparatus being provided with means controlled by the fluent material being treated to control the operation of the radiant energy ray generator. Some of the apparatus in subclasses 430 and 453.11+ of Class 250 includes electrical systems which are closely analogous to the systems in this subclass. Where the fluent material is disclosed merely as a temperature modifying medium for the lamp or discharge device, classification is in Class 315. Where fluent material is disclosed as a material being treated, classification is in Class 250.
