Abstract: A heating and cooling tray (10) for service of food comprises housing (12) which supports a Peltier temperature controlling unit (22, 24) having an air flow passageway therein. The housing includes upper and base portions (14, 16) having respective openings (60, 62) for receiving and supporting different parts of the temperature controlling unit. The upper and base portions are secured together to provide an air flow path having an entry at the front of the tray where the upper and base portions are joined at an intersection (28a) and an outlet (58) at the rear of the tray between the upper and base portions, for flow of air through the entry at the intersection, the passageway in the temperature controlling unit, and out through the outlet. A pan (85) and a thermally insulating liner (92) are spaced from one another to form a gap (99) filled with a thermally insulating foam (101) and, thus, to provide enhanced thermal insulation.

Abstract: A pivoted head lighting device for illuminating exhibit and display panels, display objects and work surfaces with substantially uniform spot-free spread of light. The device includes an elongated metal shell structure having an upper corner transition section and a lower front opening bearing a glass lens, a high intensity electric lamp tube positioned centrally within the shell structure, an elongated concave metallic light reflector within the shell structure between the lamp tube and upper corner transition section thereof, and an elongated support arm pivotally interconnected to the shell structure. The upper transition section includes integral internally-projecting tube gripping lip sections of semicircular configuration for holding a terminal cross-tubular swivel member for adjustable rotation therein. The internal cross-tubular swivel member is interconnected to an end of the support arm.

Abstract: A lighting device for illuminating exhibit, display and work surfaces with a substantially uniform wash of light. The device includes an elongated molded plastic housing having a front opening, a high intensity electric lamp tube positioned centrally within the housing, and an elongated concave metallic light reflector within the housing extending over the length thereof and positioned between the electric lamp and the rear of the housing to reflect light from the lamp outwardly through the front opening of the housing. The reflector has edge portions along its length impinging upon the edges of the housing along its length at its front opening for supporting the reflector.
