Abstract: A gearless fluidic automatic transmission with an impeller shaft driven by an existing engine. The impeller shaft is radially surrounded by a hollow frustrum with a plurality of curvilinear vanes. The vanes transfer fluid to and through a plurality of canted blades in operational communication with a turbine shaft. A power transmitted to the turbine shaft is used to drive a chosen vehicle.
Abstract: 05267372An exhaust manifold includes a curved end portion and at least two T-shaped portions connected to the curved portion through sliding fits, wherein the end portion and the T-shaped portions each are provided with a flange connection and a pipe connection, and wherein each T-shaped portion has a sliding fit connection piece. Each sliding fit connection piece is shaped by internal high pressure shaping at the outer radius of a curved section of the T-shaped portion.

Abstract: A fluid-operated transmission device has an impeller mounted within an input chamber which is driven by a motor or other motive source. A variable-speed rotor is positioned within an output chamber, the volume of which is selectively adjustable by positioning of a baffle means so that the volume of the output chamber which forms part of the fluid flow circuit may be selectively adjusted, thereby adjusting the speed of hydraulic fluid passing through the output chamber, and thereby the speed of the output rotor at constant output power. Fluid flow direction means are provided which enable braking and/or reversing direction of rotation of the variable-speed rotor by changing the direction of flow of the fluid impinging onto the impingement surface thereof.
Abstract: Gearing is normally used to obtain reverse operation from an output turbine. An improvement is provided herein in a torque converter (10) which comprises a stator (12), an impeller (14) and an output turbine (16). The improvement comprises a plurality of self-cambering blades (42) carried by the output turbine (16) with the angle at which fluid impelled by the impeller (14) attacks the self-cambering blades (42) being adjusted to select the direction of rotation of the output turbine (16). In this manner, the output shaft (36), which is driven by the output turbine (16), can be rotated in either a clockwise or a counterclockwise direction thereby driving a vehicle or other machinery in either a forward or reverse direction without the necessity for gearing.
