Abstract
1,155,959. Valves. K. L. WHITAKER. 21 NOV., 1966 [22 Nov., 1965], No. 49570/65., Heading F2V. [Also in Division F4] A flap valve located in a gas duct comprises a flexible strip 7 secured to a perforated plate 10. The Specification describes in detail a ventilation exhaust trunking (Figs. 1 and 3, not shown) having a plurality of these valves adapted to prevent back draught when the fan is inoperative.
