Latest Patents

Oldfield's latest patents include an "Apparatus for exerting a braking torque upon a rotating shaft." This device provides a retarding force against the motion of a vehicle without intruding upon the engine or being dependent on the vehicle gear selected. It is designed to avoid fade or skid characteristics. The apparatus features a multiple plate clutch that engages the vehicle's drive train with a compressor assembly. Additionally, a three-speed gear assembly is operatively connected between the multiple plate clutch and the modulation of the speed ratio between the aerodynamic rotor and the drive train. A throttle valve governs the fluid mass flow through the rotor of the compressor assembly, allowing for precise modulation of the retarding torque exerted by the rotor. This innovative device can also be adapted for other machines and motors with rotating shafts.

Another of his recent patents is an "Apparatus using aerodynamic rotors for exerting a braking torque upon a rotating shaft." This device provides a variable retarding torque and includes an aerodynamic rotor with control means responsive to external signals. The control means features a multiple disc, dynamic, torque-limiting friction clutch that varies the torque transferred between the rotating shaft and the rotor. The modulation of the dynamic clutch can occur at any time during the device's active operation.
