Abstract: The invention is directed to a termination for a surface unit having a flat spiralled active heating portion and a single, downward and laterally-extending terminal leg. The termination is particularly adapted for a surface unit of the type shown in U.S. Pat. No. 4,010,350, issued Mar. 1, 1977, to Donald M. Cunningham, and assigned to the assignee of this application.

Abstract: An electric resistance heating element, comprising at least two elongated dielectric bodies, each having a plurality of openings extending longitudinally thereon in radially displaced, parallel relation. Three metal pins fit into openings in the dielectric bodies and at least certain maintain the latter in longitudinally aligned relation. A resistance wire is wound on each of the bodies, each wire having longitudinally spaced terminals. One of the terminals of each resistance wire is electrically connected to one pin; the opposite terminal of one resistance wire is electrically connected to a second pin; and the opposite terminal of the other resistance wire is electrically connected to the third pin, whereby the one pin serves as a common electrical connection for both resistance wires, and the second and third pins serve as separate electrical connections to the respective resistance wires, whereby separate electrical circuits may be established within the heating element.

Abstract: The heating unit is particularly adapted for a stove panel and the like, and comprises a pan adapted to be supported on the panel, the pan having an opening in its side wall. A sheathed electric heating element has an active heating portion formed into a flat spiral, such heating portion being supported crosswise of the top of the pan. The heating element has at least two terminal portions extending downwardly from the active heating portion and laterally thereof, the terminal portions extending through the pan opening for connection to a source of electrical energy. A closure, formed of an elastic material, such as cured silicone rubber, closes the pan opening. The terminal portions extend through the closure and the latter cooperates with the terminal portions to provide a hinge about which the heating element may be pivoted to swing the active heating portions upwardly from its supported position on the top of the pan.
