Abstract

408,436. Pumps for concrete. NAAMLOOZE VENNOOTSCHAP INGENIEURSBUREAU VOORHEEN E. HANDL, and HANDL, E., 34, Euterpestraat, Amsterdam. Feb. 27, 1933, No. 5980. Convention date, Feb. 27, 1932. [Class 102 (i).] In a pump for concrete &c. the material is fed to a hopper 1 and passes to the pump barrel 3 through openings 2 controlled by the pump plunger 4. The discharge valve is a ported revolving disc 6, inserted between sections of the discharge pipe, and driven by means of a pinion 10. Alternatively a spring-pressed lift valve may be employed.
