Abstract

353,387. Venturi apparatus. ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Bush House, Aldwych, London.-(Assignees of Clark, G. D. ; 75, Covert Avenue, Sharpsville, Pennsylvania, U.S.A.) Jan. 14, 1930, No. 1357. Convention date, Jan. 18, 1929. Void [Published under Sect. 91 of the Acts]. [Class 69 (i).] Enlarged pockets or airtraps 3, 4 are arranged in the connections between a Venturi tube 1 and a differential pressure gauge comprising bellows 5,6. An indicating pointer is actuated by lever 16 having point contact with a rod 15, and an alarm circuit may be closed by contacts 22, 23.
