Abstract: A storage system with reversible shelf clips that can be oriented in at least two different ways to achieve variable shelf spacing. The shelf clips have a support arm that extends laterally from a clip plate and a pair of locating pins that can be slidably attached to the clip plate and inserted into the cutouts of the vertical posts. The shelf clip is asymmetrical such that the orientation of the shelf clip can be changed such that the support arm can be positioned above or below the center line of the clip plate, depending on the desired shelf height, and the locating pins can protrude from either face surface of the clip plate, allowing the shelf clips to be used in multiple orientations. The shelf clips are universal and eliminate the need for multiple parts or handed components to set the shelf spacing.

Abstract: An edible product having a thin inorganic coating on at least a portion of its surface. The coating preferably forms a moisture/oxygen barrier to result in a coated edible product having an improved shelf-life. The edible products include foods and pharmaceuticals. The inorganic materials used for the coating include SiO.sub.2, SiO, MgO, CaO, TiO.sub.2, ZnO and MnO. Processes and apparatuses for depositing a thin film of inorganic material onto an edible substrate are also disclosed. The preferred processes include sputtering and vapor deposition. The preferred apparatus provides for the continuous production of coated edible products.
