A modular drive apparatus includes a gear box (16) with a rotatable internal transmission gear (60). The gear box includes a plurality of body openings (44). The openings may be selectively closed by the installation of cover plates (52, 54). With a cover plate removed, a drive coupler (32, 34, 58, 148) may be extended in the respective opening and mounted in operative connection with the gear box. In the mounted position of the drive coupler, an idler gear (72, 172) engages the ring gear of the gear box. Rotatable power devices such as pumps, motors and generators may be operatively rotatably engaged with the drive coupler.

The present disclosure is directed to a system and a method for hydride generation. In some embodiments, the system includes an assembly for introducing hydride generation reagents into a mixing path or mixing container, where the assembly includes first chamber configured to contain a first hydride generation reagent and a second chamber configured to contain a second hydride generation reagent. A first plunger is configured to translate within the first chamber and cause a displacement of the first hydride generation reagent, and a second plunger is configured to translate within the second chamber and cause a displacement of the second hydride generation reagent. The assembly further includes base coupling the first plunger and the second plunger together.

The present disclosure is directed to an electric generator and motor transmission system that is capable of operating with high energy, wide operating range and extremely variable torque and RPM conditions. In accordance with various embodiments, the disclosed system is operable to: dynamically change the output “size” of the motor/generator by modularly engaging and disengaging rotor/stator sets as power demands increase or decrease; activate one stator or another within the rotor/stator sets as torque/RPM or amperage/voltage requirements change; and/or change from parallel to series winding configurations or the reverse through sets of 2, 4, 6 or more parallel, three-phase, non-twisted coil windings with switchable separated center tap to efficiently meet torque/RPM or amperage/voltage requirements.

A drive source switching system for a marine propulsion device includes a first drive source, a second drive source, a propeller shaft, a first driving member, a second driving member, a first driven member, and a second driven member that are movable in an axial direction of the propeller shaft, and a controller. The first driven member transmits a drive force generated by the first drive source to the propeller shaft when engaged with the first driving member. The second driven member transmits a drive force generated by the second drive source to the propeller shaft when engaged with the second driving member. When the controller moves the first driven member that is not engaged with the first driving member toward the first driving member, the controller moves the first driven member back when the first driven member fails to be engaged with the first driving member.

The control method of a ship is used for the ship. The ship is equipped with a plurality of power sources including a first power source and a second power source, and has a plurality of propulsion modes in which a power source used for propulsion of a hull is different between the plurality of power sources. The control method of the ship includes adjusting an output value related to a propulsive force of a hull to a value corresponding to an operation amount of an operation acceptor and changing a correspondence relation between the operation amount and the output value in accordance with a propulsion mode.

A motor/generator/transmission system includes: an axle; a stator ring having a plurality of stator coils disposed around the periphery of the stator ring, wherein each phase of the plurality of stator coils includes a respective set of multiple parallel non-twisted wires separated at the center tap with electronic switches for connecting the parallel non-twisted wires of each phase of the stator coils all in series, all in parallel, or in a combination of series and parallel; a rotor support structure coupled to the axle; a first rotor ring and a second rotor ring each having an axis of rotation coincident with the axis of rotation of the axle, at least one of the first rotor ring or the second rotor ring being slidably coupled to the rotor support structure and configured to translate along the rotor support structure in a first axial direction or in a second axial direction.
