DEFINITION

Classification: 219/445.1

With indicator:

(under subclass 443.1) Subject matter combined with means to display a condition of the heating device or material.

SEE OR SEARCH THIS CLASS, SUBCLASS:

109, for a current supply indicator (e.g., a recorder, etc.) to a pressure bonding (e.g., resistance welding, etc.) metal heating (e.g., resistance heating, etc.) apparatus.

248, for a heating device combined with a sole plate-type pressure application means (e.g., a flatiron, etc.) including a condition-responsive indicator.

266, for an igniter-type resistive element using resilient means for current control or external circuit connection or disconnection means.

487, for a heating device having a power supply and voltage or current regulation or current control means to control or regulate plural separate distinct heating resistance elements (i.e., one control system for all elements, etc.) selectively, sequentially, or alternately including indicator means.

506, for a heating device having automatic regulating or control means of power supply and voltage including signal or indicator means.
