Abstract: A refrigerated case shelf has a main panel comprising a top wall and left and right sidewalls, respectively depending from left and right edges of the top wall and cooperating with the top wall to define left and right channels. At least one transverse brace is secured to the main panel. A left bracket has an insertion portion within the left channel and a right bracket has an insertion portion within the left channel.

Abstract: A refrigerated case shelf (38) has a main panel (120) comprising a top wall (140) and left (142) and right (144) sidewalk, respectively depending from left and right edges of the top wall and cooperating with the top wall to define left (164) and right (166) channels. At least one transverse brace (126; 128) is secured to the main panel (120). A left bracket (122) has an insertion portion (168) within the left channel (164) and a right bracket (124) has an insertion portion (170) within the left channel (166).

Abstract: A refrigerated case top duct member (122). The top duct member is the unitarily molded combination of a main panel (132) and a number of turning vanes (150, 152) at a forward end of the main panel. The member may be formed by vacuum molding.

Abstract: A refrigerated case (20) has a base (30) and a number of supports (91, 92, 93) extending upward from the base. A number of structural uprights (70, 72, 74) are coupled to the supports. The rear supports are positioned to permit a back-to-back positioning of pair of such refrigerated cases. When so-positioned, the left end (26) of each case is substantially aligned with the right end (28) of the other case and the rear supports of each case are in a nested relationship with the rear supports of the other case.

Abstract: A refrigerated case has a base and a number of supports extending upward from the base. A number of structural uprights are coupled to the supports. At least one insulated panel is positioned between the uprights and the supports and is secured to the uprights and the supports. A refrigeration apparatus is positioned to cool an interior of the case. At least the first of the panels has front and rear liner sheets. A transversely extending polymeric layer is at least partially between the liner sheets. An insulative foam layer is between the front and rear liner sheets. A number of fasteners secure at least some of the supports to the polymeric member and at least some of the uprights to the polymeric member.

Abstract: A freezer includes a freezer compartment in which frozen items are stored and frozen. Air from the freezer compartment is drawn into a fan panel by a fan. The air is cooled in an evaporator and then returned to the freezer compartment. Flexible baffles are provided in the fan panel. During normal operation, the airflow created by the fan deflects the baffles, allowing the air to flow through the fan panel unhindered. When ice and frost forms on the evaporator, a defrost mode is initiated to melt the ice with heat generated by a heater. The fan is turned off, and the baffles drop to a straight vertical position due to gravity. The vertical baffles create resistance in the airflow and prevent the heated air and moisture generated by the heater from entering the freezer compartment and forming frost on the frozen items.

Abstract: A graphite furnace element, such as a heat shield or heating element, comprises a plurality of bent, rigid, solid and arcuate-shaped graphite sheets that have been joined together, usually by screws or bolts. The bent graphite sheets typically have a wall thickness between 0.05 and 0.5 inch.

Abstract: A sheet of high strength graphite material is bent into an arcuate shape, and the bent sheet is retained in that shape for use in a high temperature furnace. The bent sheet is rigid and can replace prior art machined blocks of lower strength graphite in a furnace. The bent sheet can also be further machined and/or further deformed into other shapes.

Abstract: A high strength graphite material is fabricated into a sheet, the sheet is bent into a tube, and the tube is retained in that shape for use in a high temperature furnace. The retained tube is rigid and can replace prior art machined blocks of lower strength graphite in a furnace. The tube can also be further machined and/or further deformed to achieve more complex shapes.
