Patent number: 11929220Abstract: An embodiment of an electric heating element is disclosed, including an electrically resistive inner heating element, an electrically resistive outer heating element, and a thermostat positioned underneath a centrally-positioned medallion and along a cold leg of the inner heating element. The thermostat is configured to selectively allow electrical current to be delivered to the inner heating element while maximum electrical current, for example, continues to be provided to the outer heating element. The thermostat cycles the electrical current on and off when detecting maximum and minimum desired temperatures radiated from the electric heating element. The inner heating element has a pair of cold legs that extend parallel to a pair of cold legs of the outer heating element, some or all of which may be supported by a terminal bracket.Type: GrantFiled: February 13, 2023Date of Patent: March 12, 2024Assignees: Backer EHP Inc., Wako (USA) Inc.Inventors: Stacy Springer, Dan Maxwell, Zachary Newcomb, Shahid Ikram, Mitch Taylor

Patent number: 9801236Abstract: A band heater assembly for heating an object includes a band heater that extends around at least a portion of a perimeter of the object. The band heater includes a cable and a band. The cable includes a resistive element, a first cable end and a second cable end. The resistive element generates thermal energy based on a current received from a power source. The first cable end and the second cable end are connected to respective ends of the band heater assembly. The band is connected to the cable and transfers a first portion of the thermal energy to an exterior surface of the object. At least a portion of the cable is exposed from the band heater to contact the exterior surface when the band heater assembly is connected to the object.Type: GrantFiled: December 4, 2015Date of Patent: October 24, 2017Assignee: BACKER EHP INC.Inventors: Stacy Springer, Ronald R. Barnes, Robert Cockrell, Lucas L. Fowler, Alvin L. Slayton

Patent number: 8571395Abstract: A heater assembly includes a heating element assembly having a resistive heating element connected to a housing member. First and second guide members are oppositely and outwardly positioned with respect to the heating element assembly and extend away from the housing member. A patch plate includes an installation aperture and first and second wings extending away from the patch plate. The first and second guide members are positioned to individually slidingly engage with one of the first and second wings thereby defining a track system to permit the heating element assembly to be slidingly received through the installation aperture without contact between the resistive heating element and the patch plate.Type: GrantFiled: September 27, 2010Date of Patent: October 29, 2013Assignee: Backer EHP Inc.Inventors: Donald E.
