Abstract

1328846 Mixing flowing liquids proportionately FACTORY MUTUAL RESEARCH CORP 8 Oct 1970 [8 Oct 1969] 48633/71 Divided out of 1328845 48633/71 Heading B1C The subject-matter is substantially that of Specification 1,238,845 but the claims relate to the arrangement whereby an additive is injected into a water flow by a second means (the pump 28) responsive to a first type of power input (mechanical), which is driven by a first means responsive to the water flow (sensing member 52 and valve 48) producing a second type of power output (hydraulic), third means (the water motor 38) being provided to convert the second type of power to the first.
