    Abstract: A unique two piece rotor construction and method of fabrication is disclosed. The rotor is cast in split positions (bifurcated along a central plane) by a shell molding or high pressure green sand technique. The portions have special pairs of interfitting mating faces, at least one being generally radially directed and at least one being generally axially directed. After the cast portions have said interfitting faces machined to a predetermined finish, and cleansed. The portions are assembled in a fixture with flux and braze material between said faces. The assembly is heated in a controlled atmosphere furnace to complete the brazed bond between said faces.

    Abstract: A rotatable drive shaft in the swash pump or turbine for liquids is supported by one bearing at each end. An integrated motor or dynamo uses the same two bearings. The compound first bearing supports a slanted section of the drive shaft placed inside the inner swash sphere, and transfers rotational power to the attached nutatable swash plate. The second bearing confines rotation of the drive shaft in a defined axis. Either one of the bearings is made to prevent axial movement of the drive shaft, preventing swash pump misalignment. A resilient drive, and an immersed pump are described.

    Abstract: A rotary type internal combustion engine having a stationary stator housing (127) and a rotor (100) which is rotatably mounted within the stator housing (127). The rotor has a thrust face (108) which is exposed to combusted gases within the engine. The thrust face (108) has a variable surface area. The stator has a profiled inner surface (152) or a contoured end cap which varies the surface area of the thrust face (108) exposed to combusting gases and thus provides the engine with a required torque characteristic. The engine further comprises a compressor assembly (132, 134, 136) located within the rotor (100) for supplying a compressed charge to a combustion chamber which includes the thrust face (108).
