DEFINITION

Classification: 219/251

(under subclass 250) Subject matter including at least one thermal operator with means for controlling a connection and/or disconnection means, or the voltage or current, in an electrical circuit to the heating unit or units of an iron.

SEE OR SEARCH THIS CLASS, SUBCLASS:

222+, for electrical hair heating or treating instruments or systems utilizing these instruments which could utilize thermal control of the individual heaters or of the system.

241, for thermal control means of electrically heated hand manipulative tools or instruments.

494+, for a thermally controlled power supply, or voltage or current regulation or control means of electrical heating means in general where more than a thermal switch or disconnect device is utilized.

510+, for thermally responsive current connection and/or

disconnection means for electrical heating devices in general. SEE OR SEARCH CLASS

116, Signals and Indicators,

101+, and 216+ for qualitative thermostatically operated, mechanically actuated signals or indicators.

200, Electricity: Circuit Makers and Breakers,

56, for switches of special application and having indicating means and subclass 167 for indicators, per se.

236, Automatic Temperature and Humidity Regulation, particularly

7, for thermally motivated operators combined with pressure application surfaces of sadirons.

307, Electrical Transmission or Interconnection Systems,

117, for thermally responsive electrical switching systems.

337, Electricity: Electrothermally or Thermally Actuated Switches, appropriate subclasses for thermally actuated switches adapted to control the connection or disconnection of an electrical circuit to the heating unit of an iron.

361, Electricity: Electrical Systems and Devices,

161+, for relay operating circuits which are thermally responsive. 374, Thermal Measuring and Testing,

141, for a nominally claimed iron combined with a thermometer.
