Disclosed is a novel system and apparatus for metering fuel with a flexural diaphragm-like divider-wall to injector nozzles for multi-cylinders combustion engines, the divider-wall providing a barrier between a fuel-chamber and a hydraulic-chamber and being motivated by circulating hydraulic liquid according to time pulses controlled by an inlet-valve and an outlet-valve, which valves are preferably of the rotary type and located within the housing for the fuel-chambers and hydraulic-chambers. The system and apparatus might have the further capability of delivering a so-called 'stratified' fuel charge to the nozzles, by sloping the intensity of each pulse of hydraulic liquid entering the hydraulic-chambers. More sophisticated systems and apparatus are suggested herein according to the exigencies and requirements of the multi-cylinders engine and its environment.

Metered fuel injection apparatus

Raw wastewater to be clarified is routed in an apparatus which directs the wastewater in an improved upwardly directed vortex path that is above and open to a source of dense microbubbles. Impurities within the wastewater are urged toward the periphery of the vortex and coagulate, while the bubbles tend to pass up through a central core of the vortex. The coagulated impurities and the bubbles approach the outlet of the vortex apparatus, whereupon a venturi-like effect is developed to accomplish an improved contacting of the coagulated impurities and the bubbles to form buoyant agglomerates. The wastewater and buoyant agglomerates flow together through the vortex outlet, after which the buoyant agglomerates may be permitted to float to the surface of the wastewater in a separate chamber.

Vortex coagulation means and method for wastewater clarification

A flow of polluted raw wastewater may first be treated with a coagulant, then it is rapidly mixed with very fine bubbles supplied beneath the wastewater flow and may then be treated with a flocculant, after which the pollutants are separated from the water by skimming off the surface of the wastewater.
