A system for co-generation of electricity combining a hydrocarbon catalytic reformer, an SOFC assembly and a generator driven by a gas turbine. The fuel cell assembly recycles a high percentage of anode exhaust gas into the reformer. Oxygen for reforming is derived from water in an endothermic process. The stack exit temperature is normally above 800&#xb0; C. DC power from the fuel cell assembly and AC power from the gas turbine generator are directed to a power conditioner. Anode exhaust gas including carbon monoxide and hydrogen is divided into a plurality of portions by which heat may be added to the reforming, gas turbine, and cathode air heating processes. Water may be recovered from the exhaust. A power system in accordance with the invention is capable of operating at a higher total efficiency than either the fuel cell component or the gas turbine component alone.

In an electrical drive system, an electric differential comprises a first rotor for driving a first drive wheel, a second rotor for driving a second drive wheel, the first and second rotors capable of independent relative rotation, and a common stator for driving the first and second rotors. The common stator may comprise a single winding for driving both rotors or first and second windings for driving the first and second rotors respectively. A processor and a sensor system monitor parameters such as torque, speed, magnetic flux, etc. to detect the loss of traction by one or both drive wheels and adjust the operation of the motor until traction is regained.

An electric starter for cranking an internal combustion engine. The starter has a solenoid which has a motor terminal. The motor terminal is connected to the electric cranking motor of the starter by conductor means which are located entirely internally of the starter. The solenoid has a battery terminal that is provided with a threaded bore that is adapted to receive a connector bolt.

Electric engine starter

An electric starting system for cranking an internal combustion engine that utilizes a starter having a solenoid that is provided with pull-in and hold-in coils. The solenoid includes a plunger which when shifted operates solenoid switch contacts and shifts a pinion into mesh with the ring gear of the engine to be cranked. The electric starting motor has series and shunt field coils and during cranking operation the shunt field is energized through the hold-in coil of the solenoid and the series field is energized through the pull-in coil of the solenoid. This mode of energization produces a small indexing torque that slowly rotates the pinion when end tooth abutment occurs between the pinion and the ring gear.
