Abstract: A cushion is disclosed having at least two coextensive overlying fluid compartments. One compartment is inflated with a compressible fluid, preferably air. The other compartment is inflated with a non-compressible fluid, preferably water. The compartments are provided with fluid communicated chambers defined between seams. The chambers and seams of an overlying compartment are at right angles to the chambers and seams of underlying compartments. Fluid communication is provided at apertures in the seams between the chambers. When inflated with water in one compartment, the air in the other compartment and supporting a user, the weight of the supported user is uniquely distributed by the two phase pressure reaction in each of the cushion compartments. Moreover, movement of the user produces a dual fluid phase hunting for a position of compressed equilibrium between the compartments and their respective chambers and seams in the cushion. Greater ease of body movement with a following cushion conformation occurs.

Abstract: A transport frame and lifting apparatus for the transport of railroad wheel sets is disclosed. The transport frame is configured for mounting to a hauling flatbed, preferably a flat truck trailer bed hauled by a fifth wheel attached tractor. The frame includes an axle support surface, preferable paired beams, spaced at less than the inside wheel to wheel distance to receive and roll the wheel sets at the medial axles. The axle support surface is a distance above the flatbed so that the wheel sets when received at the axles have the wheel peripheral rail flanges clear the flatbed. Movement of the wheels to a storage position on the transport frame occurs by rolling the wheels on the medial axles to a storage position where peripheral tie-downs secure the wheels at their rims from movement. Upon arrival at a loading and/or unloading destination, a reciprocating lever arm assembly at one end of the transport frame effects loading and unloading of the wheel sets.
