Abstract: A modular valve system in which individual valves are housed in individual, discrete, pluggable units so that they can easily be assembled. Each unit housing a valve also houses the necessary electrical circuity both to control and actuate the valves. The electrical circuit necessary to actuate a valve has its own power supply and is separate from the circuit that generates the control signal which also has its own power supply.

Abstract: Disclosed is a transmission which may advantageously utilize planetary gear assemblies. Planetary gear assemblies are characterized by no less than three independently rotatable members, each of which has associated therewith separate kinetic and kinematic properties, that is force and velocity components. These force and velocity components associated with one another create a power stream. By appropriate variation of parameters within several planetary gear assemblies comprising a transmission, including at least one parameter that is continuously and controllably variable, the kinetic, kinematic, or both, properties of the several power streams are manipulated so that all but one are eliminated thereby leaving as the sole surviving power stream one that has at least one kinetic or kinematic property which is continuously variable to form the output power stream of the transmission.
