Abstract
708,301. Forcing liquids by gaseous pressure. AVERY-HARDOLL, Ltd. Aug. 15, 1952 [Sept. 24, 1951], No. 22321/51. Class 102 (2). In apparatus for forcing liquids by air pressure, the container 10 contains a float 43 that slides on a rod 42 fitted with stops 44, 45. A lever 47 is pivoted at 48 and carries a spring- loaded pawl 53 cooperating with a lever 55 connected to a rod 57 so as to provide a snapaction of the valve 65 at the extreme limits of movement of the float 43. The valve 65 controls an atmospheric port 68 and a port 69 supplied with air under pressure. The supply of air under pressure to the container 10 forces the liquid through openings 38 in a disc 36 attached to a guide sleeve 35. The disc is maintained a short distance from the base by feet 39 and its edges are close to the housing 41 to leave an insufficient cross sectional area for the flow of liquid. The liquid thus raises the disc to uncover the ports 29. The disc in its raised position prevents the rod 42 from descending sufficiently to actuate the valve 65 to connect the container 10 to atmosphere.
