Abstract

389,075. Diaphragm air-pumps. SOC. ANON. FRANCAISE DE L'ELECTROPRESS, 220, Faubourg St-Antoine, Paris. June 4, 1931, No. 16382. Convention date, June 6, 1930. Void [Published under Sect. 91 of the Acts]. [Class 8 (i).] An air - pump comprises a flexible diaphragm 3 secured to a convex plate 7 reciprocated through its rod 11 by a crank disc 13 and connecting-rod 12. The valves are rubber sleeves 18 with conical ends pierced with narrow holes 20, e.g. by a needle.
