Abstract: A cam phase adjustor for an internal combustion engine includes a drive gear, an index gear, an actuator and a camshaft. Actuator is rotated and moves linearly to reciprocate the index gear in response to engine rpm changes. Linear movement of the index gear, which serves as the drive link between the drive gear and the camshaft, causes relative rotational motion between the spinning index gear and camshaft, thus changing the angular phase of the camshaft relative to the drive gear. This is used to advance or retard the opening and closing of the intake and/or exhaust valves of an internal combustion engine to improve engine performance over a wide range of operative engine speeds. Linear and rotational movements of the components are facilitated by cooperating grooves and balls in the respective components so there is rolling rather than sliding motion between the components.

Abstract: A viscous damped driveline coupling has two concentric tubes concentric with a torsion bar where the torsion bar is nonrotatably connected to both a drive coupling and a driven coupling. An outer tube has a first end connected to the drive coupling and a second end connected to a driven ring where the driven ring contacts ring forks contacting the driven coupling at travel stops thereby providing for lost motion between the driven coupling and the outer tube. A concentric inner tube is connected to the driven coupling and is viscously coupled to the outer tube. As the torsion bar transfers relatively low levels of torque between the drive and driven couplings, the viscous layer between the outer and inner tubes provides viscous damping. Upon contacting the travel stops, the outer tube then carries any additional torque in the driveline coupling.

Abstract: A synchronous motor/generator is modified by mounting the conventional rotor on a sleeve that rotates freely on the main shaft rather than being fixedly mounted on the shaft. Limits to this rotation are incorporated in the design such that the maximum angular rotation of the rotor on the shaft equals half the stator advance that occurs during a complete full cycle of the AC stator winding voltage. In addition to smoothing transients, this configuration permits the machine to smoothly drop into the correct stator/rotor flux phase when it changes from a motor to a generator, and back into the correct phase for a motor, when the AC power is interrupted, and subsequently resumes, resulting in dropping a single cycle.

Abstract: It is frequently observed that when a real locomotive starts up, the front set of drive wheels commences to turn before the rear set of drive wheels begins to turn. The present invention is a simple device that permits this effect to be simulated in a model locomotive. The electric motor of the model locomotive drives a worm which turns a first gear. A second gear is mounted on the same shaft as the first gear but is not otherwise connected to the first gear. From the side of the first gear that faces the second gear, a pin extends at a particular radius. Similarly, two pins extend at the particular radius from the side of the second gear that faces the first gear. When the motor starts, the first gear turns immediately, but rotation of the second gear is delayed until the pin on the first gear strikes one of the pins on the second gear. In this way a delayed rotary motion is imparted to the second gear.
