Patent ID: 8272347

Claim:
A gas heating device, comprising: one or more resistive heating elements configured to receive an electrical signal from one or more power sources; a mounting structure configured to support at least one of said one or more resistive heating elements, said mounting structure comprising: a static mounting device coupled to said mounting structure and configured to fixedly couple said at least one of said one or more resistive heating elements to said mounting structure, and a dynamic mounting device coupled to said mounting structure and configured to automatically compensate for changes in a length of said at least one of said one or more resistive heating elements, wherein said dynamic mounting device comprises a thermal break configured to reduce heat transfer between said dynamic mounting device and said mounting structure, wherein said dynamic mounting device comprises a static structure coupled to said mounting structure and having a guide feature, a helical spring configured to be received by said guide feature of said static structure, and a dynamic structure having a capture member configured to retain at least one of said one or more resistive heating elements, a slidable member configured to slidably mate with said static structure and compress said helical spring against said static structure when loaded with said at least one of said one or more resistive heating elements, and said thermal break disposed between said capture member and said slidable member, and wherein the capture member is inward of the thermal break which is inward of the sliding member.
