Abstract: A rail and track cartridge for building straight or radial belt conveyors comprises two or more rails connected to each other, wherein the two or more rails each has a first and second free end; and a track connected to each rail, wherein each track is supported by tabs protruding from the rail, wherein the track is offset to the side from the rail, and an upper track surface is above a top surface of the rail. An adjustable cartridge has bent free ends of the two or more rails attached to the same tier arm to adjust the length of the rails to fit within the tier arms.

Abstract: Spiral conveyors have a drive drum, wherein the drive drum comprises a plurality of drive drum bars connected around an outer perimeter of the drive drum, wherein a drive rod on a drive drum bar is distally located on the outer perimeter of the drive drum, wherein the drive drum bar comprises the drive rod; a face plate; and a support rib, wherein the support rib is connected to the drive rod through standoffs, and the face plate is located between the drive rod and the support rib, and the face plate is separated from the drive rod.

Abstract: A heat transfer apparatus that uses an adsorbent material to generate a cooling effect. The heat transfer apparatus includes a first vessel containing adsorbent material and a second vessel interconnected to the first. A working substance is contained within the two interconnected vessels. The adsorbent material and working substance are sized such that the working substance is completely adsorbed in both liquid and solid states by the adsorbent material from the second vessel into the first, cooling the second vessel and heating the first. Complete adsorption includes adsorption of the working substance by vaporization when the working substance is in a liquid phase and adsorption by sublimation when the working substance is in a solid phase. The second vessel contains a compressible foam which accommodates the expansion of the working substance when it changes phase from a liquid to a solid and prevents the second vessel from breaking.
