Publication number: 20130226419Abstract: A kinetic energy system incorporates multiple flywheels, each flywheel situated and adapted to develop and store kinetic energy, and to subsequently impart that energy to move a work machine. Each flywheel is controlled by an ECM to operate in a selective sequence with respect to any of the other flywheels. Each flywheel has its own individual external gear and clutch unit adapted to be in communication with a commonly shared continuously variable transmission. The plurality of flywheels may be operated sequentially to develop store, and dispense kinetic energy equivalently to that of a substantially larger unitary flywheel. In the disclosed embodiment and method of operation, the flywheel system may be employed with a traditional internal combustion engine to produce a hybrid motive source, with capability for effectively meeting transient load demands of an off-road work machine.Type: ApplicationFiled: February 29, 2012Publication date: August 29, 2013Applicant: CATERPILLAR, INC.Inventor: Jeffrey Edward Jensen

Patent number: 8499562Abstract: A geared fluid drive arrangement in which a constant speed motor is used to start a “full-size” boiler feed pump, and is able to operate the pump at a limited speed and correspondingly limited power adequate to fill, pressurize and feed water to a boiler such as would be used for an electrical generating plant to start-up and to operate stably at part load, but not necessarily full load. After the boiler is operating stably, steam from the boiler or from an extraction point of the main turbine is admitted to a mechanical drive steam turbine in order to drive the same “full-size” pump to the normal operating range.Type: GrantFiled: October 3, 2011Date of Patent: August 6, 2013Inventor: Melbourne F.
