Abstract: Aeration flotation bar comprising a shaft mounted in a tank for rotation about a vertical axis and having a plurality of wedge configured bar members. Air through the shaft is distributed lengthwise through each wedge bar member simultaneously and from each wedge bar member is emitted as a fine jet through multiple jet bores formed in the trailing surface of the wedge bars. The fine air jets create a large mass of fine air bubbles which in the aggregate provide more surface for material such as coal or other flotable materials to adhere to thereby increasing the reclamation output of the tank or cell and increasing the efficiency of the tank or cell. In addition, the location of the fine jets are such that the fine air jet streams act on the area of the tank or cell where sanding is most likely to occur and thus eliminate or minimize the sanding tendency.

Abstract: A fuel metering valve assembly includes an air flow metering member which actuates the movable part of a fuel metering valve. Depending on the displacement of this movable part, two cooperating openings, a control slot and a shaped control orifice, together define the effective flow cross section for the fuel delivered to the engine. In order to improve the resolution of the path of the moving part of the valve assembly, one of the cooperating openings, e.g. the control orifice, is formed as a triangular opening in a sleeve or bushing surrounding an axially slidable shaft which supports the air flow rate-responsive member. The triangular opening may also be defined within the wall of the shaft. The width of the control slot is defined by a spacer ring between two coaxial partial bushings and one edge of the triangular opening is defined by the oblique line separating two partial sleeves.

Abstract: An air rotor within the carburetor bore and rotated by air drawn into the bore during engine operation has extremely small diameter fuel jets associated therewith that inject fuel into the bore in counterflow relationship to the inrush of air, thereby markedly increasing atomization. In addition, the jets are directed to inject the fuel into the bore in a forward direction with respect to the direction of rotation of the rotor, hence propelling the fuel against the force of air in the bore to thereby further promote atomization. These features function independently and in cooperation with one another to increase engine operating efficiency and decrease the level of polluting emissions.

Abstract: An atomized fuel-air mixture is obtained in a heartshaped chamber of a rotating member which is mounted in the combustion air inlet duct of an internal combustion engine. Fuel and a gaseous medium are injected into the chamber and are thoroughly mixed by a fuel flow dividing portion formed by the curved walls of the chamber in axial alignment with the fuel injection nozzle, which deflects the fuel flow from the axis of rotation towards the periphery of the chamber. Outlet channels exhaust the fuel-gaseous medium mixture from the chamber and impart a rotational force to the member.

Abstract: A carburetor for an Otto cycle engine comprising a mixing compartment through which flows a suction air current regulated by means of a regulating valve. In the mixing compartment there is prepared from the dosed fuel delivered by nozzle means a fuel-air mixture for the Otto cycle engine. Within the mixing compartment there is arranged an impeller driven by the suction air current, this impeller containing a fuel compartment into which opens a fuel delivery channel. The nozzle means embody nozzle channels which lead away from the fuel compartment, these nozzle channels rotating with the impeller and fuel is sprayed from spray nozzles of the nozzle channels during rotation of the impeller owing to an excess pressure brought about by the centrifugal forces, the fuel being sprayed out of the fuel compartment into the mixing compartment.

Abstract: Apparatus including a mixing chamber has a hollow rotor mounted therein carrying a stack of tightly pressed together nebulizer rings made of pliant material characterized by having substantially constant dimensions. A selected gas, such as air, is supplied to the mixing bowl while liquid fuel and optionally water or other liquid additives are metered into the interior of the hollow rotor at a rate controlled as a function of the air flow into the chamber. The fuel and water are each nebulized and uniformly dispersed into the mixing chamber by being propelled by centrifugal force generated by the rotor between the smooth uniform laminae defined by the pressed together nebulizer rings. The rotor is preferably driven to operate as a Van de Graaf generator and the nebulizer rings are preferably made up of dielectric materials to induce substantial electrostatic charges on liquids propelled therebetween.

Abstract: A cyclonic gas cleaning system is described having an elongated rotary spray header mounted centrally of an elongated housing coextensive therewith. Gas circulates helically upward within the housing while the spray header rotates and sprays a scrubbing fluid into the gas.
