Abstract: A conveyor beam including an endless, vacuum conveyor belt supported at its ends by drive pulleys and in the center by a vacuum manifold. Perforations in the belt register with an elongate slot in the manifold, in line with the direction of belt movement, to grasp and retain objects on the belt. Guide pins are secured on the inner surface of the belt, interspersed with the perforations, adapted to project into the slot and slide therealong to maintain the moving belt in alignment. The upper surface of the manifold and the edges of the slot are lined with a material having a low coefficient of friction, such as graphite impregnated nylon.

Abstract: A decorative panel product formed through compressing and consolidating a mat of loosely organized, bondable wood particles. The panel includes a medial portion having one thickness and one density, and a marginal portion having a substantially lesser thickness and a greater density than the medial portion. The panel''s marginal portion is slotted, whereby a pair of spaced substantially parallel flanges are defined which can be squeezed toward one another to facilitate fitting the extremities of the marginal portion into grooves in a supporting framework.
