Abstract: A refrigerated case with reduced frost operation includes a housing having an open front and defining a product storage space therein. A contact cooling device or gravity cooling device is disposed within the space to receive chilled liquid coolant from a coolant system supply header and to return warmed liquid coolant to a coolant system return header. An air flow device in an air flow path directs a flow of air over a dehumidification coil that operates frost-free at a temperature of greater than 32° F. for discharge as a dehumidified air curtain over the open front. A precooling coil is provided in the air flow path upstream of the dehumidification coil, the precooling coil receives warmed liquid coolant from the coolant system return header to precool the flow of air, so that the dehumidified air curtain operates as a humidity tempering boundary to minimize the humidity within the storage space.

Abstract: An adjustable shelving system is disclosed for an open-front refrigerated display case having an air-curtain at least partially across a front of the display case and having a shelf configured to hold products to be displayed. A first bracket and a second bracket are coupled to an interior panel of the display case where each bracket includes a first travel stop and a spaced-apart second travel stop. The shelf has pin members that interface with the brackets and engage the travel stops. The pin members engage the first travel stop to retain the shelf in a first position and engage the second travel stop to retain the shelf in a second position having an angle of inclination relative to the first position. A distance from a front edge of the shelf and the air curtain is substantially constant between the first position and the second position.

Abstract: An X-ray inspection system for manually or automatically performing digital fluoroscopy inspections and/or computed tomography inspections by X-ray examination of manufactured parts incorporates a computer system which automatically analyzes the inspected parts for flaws. The system includes apparatus for automatically positioning the parts in an X-ray machine for obtaining fluoroscopy and tomography views of the part and for acquiring data from the inspections at production rates. The system automatically identifies the location of rejectable flaws in the parts during the fluoroscopy scanning and subsequently identifies those locations for obtaining tomography scans, if the identified flaw location is questionable. The system can automatically reject parts containing flaws identified during the fluoroscopy inspections. This system operates in a real-time environment by providing analysis of one part while a subsequent part is being subjected to X-ray examination.
