Abstract: A protective cover and display device for a checkout countertop having a code scanner includes a sheet of material adapted to cover the scanner opening and adjacent portions of the countertop. The sheet includes a transparent window in the portion overlying the scanner opening and visually perceptible indicia, such as advertising copy, on the portion of the sheet surrounding the opening. In addition to providing advertising which is highly visible and disposed in a high traffic area, the sheet covers and protects the scanner opening which is typically a repository for the accumulation of dirt, food particles, and other foreign materials.

Abstract: The invention is a work holding system for adjustably receiving and holding printed circuit boards for automatic machine component insertion. It includes a frame and a plurality of mutually cooperative adjustable board holders. The frame is U-shaped and is made up of framing members each having a linear scale affixed thereto. An adjustably positionable framing member extends across the U and is slidable along the opposed framing members toward and away from the base framing member forming the bottom of the U. Means are provided for indexing, locking the adjustably positionable member to the frame in any desired position. A linear scale is also carried by the adjustably positionable member and all scales have a common datum. The frame carries indexing means to index it to the machine which inserts components. A number of adjustable board holders are slidably carried by the base framing member and the adjustably positionable framing member to receive circuit boards therebetween.

Abstract: The invention comprises a universal circuit board holding apparatus having a frame with side, front and rear rails. Adjustably positionable rails extend across the frame between the side rails and they are movable in the direction of the front and rear rails. Releasable clamping means engage the side rails and the adjustably positionable rails, permitting movement of the adjustably positionable rails along the side rails when released and for automatically locking the adjustably positionable rails to the side rails when clamping. Circuit board supports are carried by the adjustable rails and either or both of the rear and front rails. Further releasable clamps positionably fix the circuit board supports to the rails while permitting movement therealong upon release to accommodate various sized boards.
