Pultruded panels having a first longitudinal edge profile and a second longitudinal edge profile may be used to form a floor assembly mounted on a railway car underframe. The pultruded panels may also be used to form walkways, bridges, piers and other structures. A bead may be placed on at least one of the longitudinal edge profiles to form a gap between an adjacent pultruded panel. An adhesive may be placed within the gap to couple or bond adjacent pultruded panels with each other. Void spaces may be formed within the pultruded panel and filled with foam to provide improved resistance to heat transfer through the respective panel. Respective coverings may be placed on opposite ends of each panel to block access to the associated void spaces.

The energy-free refrigeration door of the present application provides a way to control condensation when the door of a refrigeration unit is opened by providing thermal insulation to the door with glass panels which have a low emissivity coating. The door includes a door frame housing and an insulating glass unit comprising inner, middle and outer sheets of glass. A first sealant assembly disposed around the periphery of the inner and middle sheets of glass forms a first chamber between the inner and middle sheets of glass. A second sealant assembly disposed around the periphery of the middle and outer sheets of glass forms a second chamber between the middle and outer sheets of glass. A gas, such as krypton, air, or argon is held in the first and second chambers. The outer sheet of glass and inner sheet of glass each have an unexposed surface that faces the middle sheet of glass. A low emissivity coating is disposed on the unexposed surfaces of the inner and outer sheets of glass so that the glass door as a whole avoids formation of condensation on the outer surface of the outer sheet of the glass door, without the application of electricity to heat the door, while also providing the desired evaporation rate of condensation from the inner side of the inner sheet of the glass door. An anti-fog or anti-frost coating is included on a surface of one of the sheets of glass.

A method of fabricating an electrostatic actuator with an intrinsic stress gradient is provided. An electrode is formed on a substrate and a support layer is formed over the electrode.

The intrinsic stress in the metal layer increases in the direction from the bottom to the top of the metal layer. The support layer under the electrode is removed to release the electrostatic actuator.

An improved mathematically modeled family of bellow fold patterns, useful for making bellows from stiff but foldable materials, which forms a corner of a bellow consisting of a series of several single inversion fold patterns, each having a characteristic design angle which is mathematically computed to provide a desired initial wall angle for the bellow and to minimize wall tilting over a predetermined extension angle range, thereby allowing low cost bellows to be made which can extend long distances while using a minimal amount of stiff but foldable material. In addition, each characteristic design angle can be computed to provide exactly zero tilting of the bellow walls at one or more non-zero extension lengths specified by a designer, thus allowing, unlike all other prior art folds, a structurally stiff, long extending bellow to be formed in an extended state using fast production techniques such as vacuum forming, blow molding or injection molding, while also allowing the bellow to be free of distortion in the compressed state.
