Patent number: 8393926Abstract: A hybrid marine power train system is provided that facilitates selective use of one of multiple prime movers for powering and driving a boat. The multiple prime movers can include an internal combustion engine and an electric motor which can itself be part of a motor/generator assembly. The system further includes a power-take-in assembly that can have either an active or passive clutching device for selectively importing power from the prime movers into the transmission. The system is configured so that the second prime mover occupies relatively little space within an engine compartment of the boat, for example when compared to an amount of space occupied by the first prime mover and transmission. Since the second prime mover occupies relatively little space within the engine compartment, the system can be readily retrofitted to existing marine power train systems.Type: GrantFiled: May 29, 2009Date of Patent: March 12, 2013Assignee: Twin Disc, Inc.Inventor: Dean J. Bratel

Publication number: 20120001436Abstract: An electric power generating system is provided that uses a wind turbine to generate waste-heat that is utilized in an organic Rankine Cycle drive that converts heat energy into rotation of a generator rotor for generating electricity. A hydrodynamic retarder may be provided that dissipates heat into a hot fluid by directing the flow of the fluid through the hydrodynamic retarder in a manner that resists rotation of blades of the wind turbine. The hot fluid circulating in the hydrodynamic retarder is a thermal heat source for vapor regeneration of organic heat exchange fluid mixture(s) used in the Rankine cycle, expansion of the organic heat exchange fluid being converted into rotation of the generator rotor.Type: ApplicationFiled: December 20, 2010Publication date: January 5, 2012Applicant: TWIN DISC, INC.Inventors: Samuel M. Sami, Edwin E. Wilson, Dean J. Bratel, John H. Batten

Patent number: 7617026Abstract: A programmable trim control system for marine applications preferably includes a controller, a control panel, a display device and a plurality of sensors. The controller receives input from the control panel and the plurality of sensors. The display device acts as a monitor for the controller. Each sensor monitors a single drive device, trim device or operational parameter. The controller further includes output ports connected to the drive devices and trim devices for controlling thereof. The trim control system preferably includes a manual mode, a diagnostic mode, a program mode and a preset mode. The positions or settings of the trim and drive devices are set in the program mode and recorded in the controller. Data stored in the controller will be accessed by the trim control system when in the preset mode.Type: GrantFiled: May 17, 2006Date of Patent: November 10, 2009Assignee: Twin Disc IncorporatedInventors: Michael B. Gee, Dana L. Birkland, Robert B. Bertolasi, Darryl S. Babu, Klaus Meyersieck, Dean J. Bratel, David D. N. Vann, Steven B. Hall, Mark B. Wilson, Russel E. Gates, Frederic E. Nystrom, Robert N. Schenk

Publication number: 20080281478Abstract: A programmable automatic trim control system for marine applications preferably includes a controller, a control panel, at least one display device and a plurality of sensors. The controller receives input from the control panel and the plurality of sensors. Each display device shows various data from the controller. Each sensor monitors a single drive device, trim device or operational parameter. The controller further includes output ports connected to the drive devices and trim devices for the control thereof. The trim control system preferably includes a manual mode, a diagnostic mode, a program mode and an automatic mode. The positions and/or settings of the trim and drive devices and operational parameters are set in the program mode and recorded in the controller. Data stored in the controller is accessed and utilized by the trim control system when in the automatic mode.Type: ApplicationFiled: February 12, 2007Publication date: November 13, 2008Inventors: Michael B. Gee, Dana L. Birkland, Robert B. Bertolasi, Darryl S. Babu, Klaus Meyersieck, Dean J. Bratel, David D.N. Vann, Steven B. Hall, Mark B. Wilson, Russel E. Gates, Frederic E. Nystrom, Robert N. Schenk

Patent number: 6443286Abstract: A modulatable power transmission clutch including interleaved clutch plates and having a central power transmitting shaft extending axially through the clutch. The clutch includes a fluid operated movable piston for effecting clutch operation by compression of the plates. The piston has a smaller piston area and a larger piston area, the smaller piston area has fluid flow directed to it a variable fluid pressure whereby the clutch is modulatable. The larger piston area is adapted to have fluid flow directed thereto to effect maximum and unmodulatable engagement of the clutch. A spring loaded normally closed trigger valve controls fluid flow to the larger piston area in response to fluid pressure above a predetermined amount at the smaller piston area. The trigger valve is mounted in the shaft and is normally closed so that pressure fluid is directed to the smaller piston area at a variable fluid pressure whereby the clutch is modulatable.Type: GrantFiled: January 18, 2001Date of Patent: September 3, 2002Assignee: Twin Disc, IncorporatedInventors: Dean J. Bratel, Paul A. Pelligrino
