Abstract: A supplemental computer readable medium is applied to an existing credit card of a customer by a merchant at the point of sale or place of business with a lightweight, simple applicator. The use of supplemental computer readable media on existing cards reduces the bulk that must be carried by the customer, and provides the customer with a computer readable medium in a convenient format.

Abstract: The cone-shaped or dome-shaped sheet of waxed paper or freezer paper having a moisture retarding coating on at least the surface of the paper facing an underlying dish bearing food and positioned within a microwave oven, and being microwave transparent traps moisture condensing on the interior surface thereof for revaporization for return to the food being heated and/or cooked while preventing the dripping of condensed moisture directly onto the food within the underlying dish. Preferably the conical or dome-shaped cover is mechanically embossed to form vertically spaced annular concave cavities facing inwardly to trap the moisture running by gravity down the interior surface of the cover within the cavities for revaporization. Additionally, circumferentially spaced reinforcing ribs may be formed over the height of the cover to maintain the cover one or dome shaped configuration throughout the microwave oven heating process.

Abstract: A corner mount fastener adapted to mount an apertured panel at its corner to a hard concrete vertical wall is L-shaped in plan configuration, is formed of molded plastic, each leg of which having a base defined by a front vertical wall and a rear stepped vertical wall when mounted to said concrete wall, with a transverse inner wall forming a projecting transverse lip defining a slot to receive the edges of the apertured panel at the received corner. Integral spring fingers project from the stepped portion of the vertical rear wall to frictionally lock the apertured panel to the fastener and mounting pins, supported within vertical integral cylinders between the inner and outer walls, are driven into the concrete wall to lock the fastener to the concrete wall after insertion of the corner of the apertured panel within the fastener slots.
