Abstract: A device for forming a solid support surface adjacent an open wire shelf having a front support member, a rear support member and a plurality of intermediate wire members which have longitudinal openings therebetween wherein the solid support surface is flexibly resilient to be snapped in place between a slot defined in the ticket molding secured along the front support member of the open wire shelf and the rear support member thereof. The cover plate of the solid shelf device preferably is of a plastic or spring steel material to facilitate placement thereof between a slot defined by the ticket molding and the rear support member.

Abstract: A refrigerated food display case of the closed front type is provided with an improved means for inhibiting the formation of condensation on the front display window. To this end, the display case includes means dividing chilled air circulated within the case, into primary and secondary air curtains flowing across the display window. A heating means mounted only within the secondary air passage operates throughout each refrigeration cycle, to heat only the chilled air flowing within the secondary passage, thereby forming it into a secondary air curtain interposed between the window and the primary, fully chilled flow of air that has passed through the primary air passage and hence has not been exposed to the heating means. The warm air curtain, impinging upon the surface of the window, inhibits the formation of condensate thereon, such as commonly occurs due to the disparity of ambient temperature and the lower, interior case temperature.
