Abstract: A surface finishing apparatus for in-line outer surface polishing of elongate cylindrical metal stock to apply a long scratch finish, including a stock feeder for feeding a length of stock through the finishing apparatus from an infeed downstream to an outfeed position while rotating the stock about its longitudinal axis and a polishing assembly for finish-treating the outer surface of the stock as the stock is fed through the apparatus to apply a long scratch finish thereto. The polishing assembly includes a rotatable finishing wheel having a finish-treating peripheral surface for being applied in an in-line orientation against the outer surface of the stock as the stock is simultaneously fed and rotated through the finishing apparatus.

Abstract: This display system includes tubular frame components which are easy to assemble, disassemble and rearrange to form various types of display units. The frame components are provided with interlocking connector means which includes a multi-sided stud extending outwardly from one end of one frame component and the other frame component has first and second multi-sided openings provided in opposite walls thereof and aligned perpendicular to the longitudinal axis of the frame component to receive the multi-sided stud therein. Means is provided for removably locking the multi-sided stud of one frame component in the first and second multi-sided openings in the other frame component to rigidly maintain the adjacent end of the one frame component against one wall of the other frame component and in right-angular and non-rotating relationship thereto.
