In order to supply sufficient electric power to an induction heating mechanism even with a small-diameter roller, an induction heated roll apparatus includes a roller body having a hollow cylindrical shape, a drive shaft provided at each of both ends of the roller body and rotatably supported, an induction heating mechanism that is provided inside the roller body and allows the roller body to inductively generate heat, and a support shaft that extends from both ends of the induction heating mechanism and supports the induction heating mechanism. The support shaft is rotatably supported on an inner peripheral surface at both ends of the roller body via a bearing.

Heat engines employing fluid bearing assemblies hermetically sealed with a closed flowpath for a working fluid are generally disclosed. For example, the heat engine includes a rotating drivetrain and a fluid bearing assembly. The rotating drivetrain includes a compressor section, an expander section, and a heat exchanger. The compressor section and expander section together define at least in part a closed flowpath for the flow of a working fluid. The heat exchanger is thermally coupled to the closed flowpath for adding heat to the working fluid. The fluid bearing assembly is configured to utilize the working fluid to support the rotating drivetrain. Further, the fluid bearing assembly is hermetically sealed with the closed flowpath.

An apparatus and method of an extending rack for a cooking appliance. One or more bushings slidingly engage one or more sliding rods allowing a wire rack or structure to travel between positions relative to a remaining portion of the extending rack. One or more support rods may be used with the sliding rods. The extending rack may include one or more retaining clips engaging the one or more bushings to the wire rack.

The present disclosure is directed to drive shaft assemblies for a rotary furnace. In one form, a rotary furnace comprises a crucible and a drive shaft assembly. The drive shaft assembly comprises a primary shaft and a secondary shaft coupled with the primary shaft. The secondary shaft comprises: a first portion comprising a refractory alloy, the first portion defining a first end and a second end, where the first end of the first portion is configured to couple with the primary shaft; and a second portion comprising graphite, the second portion defining a first end and a second end, where the first end of the second portion is configured to couple with the second end of the first portion and the second end of the second portion is configured to couple with the crucible.
