Abstract: A portable office device is adapted for use with a seat in a vehicle to form a desk and preferably has a main body with a plurality of storage compartments, an angled bottom, and a two-piece, hinged work surface member affixed to the main body that is selectively positionable between an open and closed position. When open the work surface member includes an expanded, co-planar work surface suitable for writing or a laptop computer. The portable office device also includes a receptacle adapted to removably receive either a spacer or a filler member/plug, where the spacer and plug enable the portable office device to be selectively positioned within the vehicle providing a greater range of convenient and comfortable use for users of the device. The ability to selectively position the office device in the vehicle passenger compartment, along with a two piece work surface member and an angled bottom, creates a convenient apparatus for both working on and storing work related items in a vehicle.

Abstract: A high temperature furnace chamber includes a roller hearth for supporting and transporting workpieces to be heated. The rollers are supported at each end by a rotary sleeve having an inner diameter larger than the outer diameter of the rollers. Rotary movement of the sleeves transmits rotational forces to the rollers. Clearance provided between the rollers and the sleeves allows for roller dimensional variation during various furnace operating conditions.
