Abstract: A shelf in a cooled compartment (10) has gaskets (32,42) selectively attachable and removable at sides (22,24,26) of the shelf. The gaskets (32,42) are configured to obstruct the flow of air at at least a portion of a gap between the shelf and a wall (14,16,18) of the compartment (10) on the side of the shelf where the gasket is attached.

Abstract: An air tower assembly includes an outer housing, a duct with a damper opening, a damper configured to control a flow of air from a freezer compartment to a fresh food compartment, and at least partially transparent rear cover sheet attached to a rear of the outer housing that contains the duct and the damper within the air tower assembly. The rear cover sheet may be transparent or may have a clear or semi-opaque surface configured to allow visual confirmation of the damper during assembly, operation, and service. An air passageway is provided between the freezer compartment and the fresh food compartment to allow air to flow from the fresh food compartment to the freezer compartment.

Abstract: A process for preparing thermoplastic piping for recovery of the thermoplastic in which the piping is cut into a continuous spiral ribbon with straightening of this ribbon to be without substantial curvature and cutting of the straightened ribbon into pieces. Preferably, the process produces pieces of thermoplastic of sufficiently small size to be suitable for feeding to an extruder. An apparatus for preparing thermoplastic piping for recovery of the thermoplastic which combines means for cutting the thermoplastic piping into a continuous spiral ribbon with means for straightening the spiral ribbon so that it is without substantial curvature and means for cutting the straightened ribbon into pieces.
