Abstract: A central differential power output delivery shaft for a rotary motor used to deliver the power to the drive wheels in a motor vehicle application. The power delivery shaft is a hollow two piece housing which internally houses two separate independent axle shafts, one protruding from each of its ends for the purpose of providing differentiated rotation to the drive wheels of a motor vehicle. The axle shafts rotate along with the central differential power output delivery shaft and are internally operationally connected to the left hand and right drive wheels of the motor vehicle. The axle shafts are also operationally connected to each other inside the central differential power output delivery shaft housing with a geared differentiating arrangement so as to allow them to rotate at different rates with respect to one another.

Abstract: The present invention provides a spot resistance welding electrode cap for welding two or more work-pieces together, including a substantially cylindrical body having an interior surface, an exterior surface, and a tapered interior cavity for frictionally fitting over an electrode shank. The exterior surface of the body includes a plurality of longitudinally extending depressions or flutes formed therein which provide an increased external surface area to the electrode cap, thus increasing the ability to transfer additional amounts of heat. The electrode cap further includes a plurality of fins disposed on the interior surface of the body within the interior cavity. The free ends of the fins are chamfered in order to ease the transition of coolant flowing throughout the shank proximate the electrode cap.
