Abstract

818,099. Forcing liquids by gaseous pressure. GASKELL & CHAMBERS Ltd., [trading as NON-DRIP MEASURE CO.]. Dec. 3, 1957 [Dec. 17, 1956], No. 38447/56. Classes 8(1) and 102(2). An air pump for creating alternate pressure and suction in a liquid chamber having valve controlled liquid inlet and outlet passages has a restricted passage 13 through the piston controlled by a non-return valve 14 so that on the suction stroke air may flow into the cylinder. The restricted passage and valve may be provided on the cylinder. Specification 634,632 is referred to.
