Abstract

The frame forms a flat tank (1), the upper surface (8) being pierced with holes (9) at regular intervals. On this surface is placed a bed (3) having holes (4) coinciding with those in the frame. Each hole (4) has a lower inverted funnel section joining the straight section (5) communicating with the surface. A ball (7) is loose in the conical section (6) and, when the blower (2) is running, air pressure keeps the ball in the top of the cone, allowing a small escape of air. When the load covers the holes, the back pressure generated pushes the ball off its seat and the air cushion is formed.
