摘要： An electric heating element having an improved electrical termination. The heating element comprises a conventional tubular metal sheath with a heating coil embedded in granular refractory material which is contained within the sheath. Terminal pins are electrically connected to opposite ends of the heating coil and extend outwardly of opposite ends of the sheath. My improvement provides for easy and efficient connection of a power conductor to a terminal pin and includes a metal sleeve having interengagement with a respective sheath end to provide protection for the terminal connection.

摘要： A split-band heater adapted to encompass a cylindrical object for heating the same. The heater has tensioning means at the split for drawing the heater against a transverse peripheral surface of the object. The heater comprises two or more arcuate-shaped metal-sheathed heater sections, each in the form of a strip heater, each section being adapted for positionment along a respective portion of the transverse peripheral surface of the object.Each strip heater comprises an elongated metal channel having a planar base wall and a pair of coextensive side walls extending in the same direction from the edges of the base wall, the channel containing a resistance wire and electrical insulation means therefor, both disposed lengthwise within the channel, and an elongated metal strip fits transversely within the channel. The side walls of the channel are bent over adjoining longitudinal margins of the metal strip to lock it and the resistance wire and insulation means within the channel. Each strip heater is arcuately bent so that its base wall is located innermost of the arc and adapted to fit along the curved transverse outer surface of the cylindrical object. The strip heaters are arranged in spaced-apart, end-to-end relationship as longitudinal continuations. A juxtaposed pair of spaced strip heater ends defining the split have the tensioning means connected thereto, the remaining juxtaposed pair of spaced ends being connected together by the flexible metal band which may be fixed thereto to become a part thereof, or may be an integral continuation of the base walls of the heater sections.
