Abstract: A reduction drive gear for all-terrain vehicles (ATV) such as the HONDA RINCON™. The gear reduces the drive ratio, thereby increasing the load pulling capacity of the vehicle and providing for a lower-end torque. It is comprised of a carbon steel bar cut to a seventeen-tooth drive gear (as opposed to the original nineteen-tooth drive gear found in typical ATVs). The reduction drive gear enables the ATV to be more powerful while avoiding any modifications to the motor, thereby eliminating the creation of undesirable heat in the motor.

Abstract: The number of on-line locomotives of a consist is either reduced or increased by a manual control system that conserves fuel by throttling back trailing locomotives and operating the remaining locomotives of the consist at the most efficient throttle position. A control unit in the lead locomotive is operated by the engineer to command control units in equipped trailing locomotives of the consist. Each time the engineer depresses a "subtract power" push button, one trailing locomotive is throttled back; conversely, each time an "add power" push button is depressed, a trailing locomotive is returned on line by advancing its throttle to the most efficient position. A cutout control signal, which is generated in the lead locomotive and transmitted to trailing units in serial order (front to rear) by a single spare trainline wire, has voltage levels that progressively decrease or increase in response to the subtract or add power commands.

Abstract: An automatic speed control system for a consist of diesel locomotives conserves fuel by throttling back trailing engines and operating remaining engines at the most efficient throttle position. A control unit in the lead locomotive is operated by the engineer to command control units in equipped trailing locomotives of the consist. In the lead locomotive, depressing a "set speed" push button causes a speed memory to store the existing speed of the consist, and a cutout control signal is generated which is transmitted to trailing units in serial order, i.e., front to rear, by a single spare trainline wire. The control signal has two control voltage levels that increase or decrease with deviations of the speed of the consist from the desired speed in memory. These voltage levels are decoded by each trailing unit and, if power is needed, the engine throttle is set at the most efficient position or, if the locomotive is to be cut out, the throttle is set at a desired minimum position.
