Abstract
708,984. Centrifugal fans. PARTRIDGE, W. H. March 24, 1953 [March 24, 1952; Nov. 24, 1952], Nos. 7554/52 and 29695/52. Class 110(1) [Also in Group XIII] A stream of cold air is maintained over a display surface 1 by a radial flow impeller 8 extending the full length of the edge of the surface 1, the air passing through a slot in the impeller housing 4. As shown applied to an open-topped display stand a metal base 3 spaced below the display surface 1 carries an air cooling unit 9 adjacent to a cylindrical housing 4 through which runs a shaft 5 carrying the impeller blades 8, the edges of which an inclined to the inner portions. The impeller draws air from beneath the surface 1 and forces it as a blanket along the surface, the air returning to the space beneath the surface 1 through a gap 10 at the front edge. In a modification a number of impellers are spaced along the shaft 5 and supplied separately with cold air through gaps in a cylindrical housing, communicating with the space below the surface 1. Each impeller section may include a propeller 16 to drive cold air axially into the section whereafter it is expelled radially by the vanes 8. The top may be closed or have hinged lids.
