TL;DR: In this paper, the air regulation in the blower shaft is provided by series of flaps mounted parallel to one another, close together when closed and fitting close against the sides of the air inlet opening, and able to swivel about their centres.
Abstract: The air regulation in the blower shaft is provided by series of flaps mounted parallel to one another, close together when closed and fitting close against the sides of the air inlet opening, and able to swivel about their centres. When activated, adjacent flaps swing in opposite directions of rotation, so as to effect an axis-parall inflow of blower air. This alternating movement cam be achieved by using chain-wheels connected to the flaps, gripped alternately left and right by a chain; so that when this moves they are turned alternate ways; or interlocking spur wheels may be used. The flaps are pref. less then 80 mm. wide. Formation of eddies is prevented.

16 Jun 2003TL;DR: In this article, a chairmat with a gripping surface formed from a plurality of interlocking ridges extending from the bottom of the mat is disclosed, and each of the interlocking shapes may be configured so as to form a plurality or arcuate shape.
Abstract: A chairmat having a gripping surface formed from a plurality of interlocking ridges extending from the bottom of the mat is disclosed. Each of the interlocking ridges may be configured so as to form a plurality of interlocking shapes, such as hexagons, rectangles, other polygons, or arcuate shapes. In so doing, not only is the mat provided with a mechanism by which the underlying surface can be gripped, but also is provided in a form which prevents the formation of any sharp edges on the bottom of the mat which would otherwise be negatively viewed by consumers and sales personnel.
