Abstract: A reaction turbine has channels formed in the top surface of a disc to create nozzles. The channels can be covered by a membrane sealed to the disc or by the housing extended from a combustor. Each channel may have a first section extending radially outwardly from an inlet of the reaction turbine and a second curved section extending from the first section to a periphery of the disc. A reaction turbine may also receive input from an impulse turbine. Fluid flows through the impulse turbine and fluid from the impulse turbine enters an inlet of the reaction turbine. The reaction turbine may have cooling channels and cooling fins to lower the temperature of the disc during operation. In addition, magnets may provide bearing support and electricity generation. In addition, the reaction turbine may have a dual shaft construction, with each shaft connected to a reaction turbine. One reaction turbine powers a compressor, while the second reaction turbine powers a load through the second shaft.

Abstract: Improvements in a flywheel engine are described which includes a flywheel with non radial propulsion units for generating thrust by combustion to rotate the flywheel in a first direction about a flywheel axis. A drive shaft mounts the flywheel for rotation about the flywheel axis within a housing that completely encloses the flywheel. A turbine is also mounted within the housing. It includes turbine blades positioned to react against thrust from the propulsion units and rotate in a second direction opposite to rotation of the flywheel. A transmission is connected to the turbine for producing torque responsive to rotation of the turbine.

Abstract: An apparatus for agitating and transforming settled sludges into slurries which are then capable of being pumped by conventional means. The apparatus comprises a housing immersible in the contents of a tank or chamber and containing separate variable drive means for an impeller and an impeller casing. The impeller casing forms an inlet to the impeller and has a plurality of radially directed outlet nozzles whereby rotation of the impeller effects circulation of the contents of the tank or chamber from the inlet to the outlets and rotation of the casing causes the discharge at the outlets to agitate the contents. The discharge at the outlets breaks up solid sediment at the bottom of the tank or chamber and a continuous recirculation of the contents results in the formation of a slurry.

Abstract: This invention relates to a centrifugal pump characterized by a pair of novel self-aligning impeller hub seals located in the high pressure cavity and subjected to the influence thereof to maintain them in fluid-tight sealed contact with the adjacent cavity walls to which they are loosely fastened. The invention also encompasses a novel thrust-type hub seal subassembly that is continually biased into fluid-tight sealed contact with an annular abutment on the impeller hub, the latter element being the only surface in relatively movable frictional engagement with the seal with such engagement being face-to-face so that the thrust compensates for any wear therebetween. Another feature of the invention is the cooperative relationship between the self-aligning impeller hub seals, the thrust-type hub seal and pressure relief passages in the impeller hub whereby the thrust seal is isolated from the relatively higher fluid pressure in the high pressure cavity.
