Abstract: A refrigerated case and display lamp arrangement is provided which case may be alternately cooled and heated for defrosting purposes. An elongated tubular fluorescent lamp is mounted within the case and is provided with tubular jacket spaced coaxially thereabout. Elastomeric support members are disposed at either end of the lamp to hold the jacket in a particular spaced relationship with respect to the lamp. Axially extending grooves are formed in a radial face of each support member to receive the terminal edges of the tubular jacket. The outer surface of each supporting member is formed with a circumferentially extending recess for receiving a steel ring which biases axially extending surfaces of each supporting member into pressure engagement with both the tubular jacket and a glass portion of the fluorescent lamp. A spacer member may be positioned about the fluorescent lamp approximately at the mid-span thereof for insuring a constant spaced relationship between the jacket and the lamp along the entire length thereof.

Abstract: A Duct and Blower Arrangement is herein described which duct may be formed to define an opening in a side wall portion thereof to receive the blower. A flange may be formed in the duct for operatively supporting the blower within the duct, upon inserting the blower therein. A closure member may be connected with the blower for covering the opening in response to the proper insertion of the blower into the duct.
