Marine Transmission Using Rheological Fluids

View page
US Patent:
8127907, Mar 6, 2012
Filed:
Feb 3, 2009
Appl. No.:
12/364866
Inventors:
Brian R. White - Stillwater OK, US
Keith S. Ducotey - Stillwater OK, US
Brian S. Ritthaler - Stillwater OK, US
International Classification:
B63H 20/20
F16D 47/06
F16D 37/02
F16D 35/00
US Classification:
192 215, 192 482, 192 485, 192 51, 192 57, 440 75
Abstract:
A marine transmission provides first and second drive gears that have first and second driving surfaces in contact with first and second quantities of rheological fluid. First and second driven surfaces of a propeller shaft are also in contact with the rheological fluids within first and second cavities. Torque is transmitted between the drive gears and the propeller shaft through the increase in viscosity of the rheological fluid. A dog clutch can also be provided in order to lock the propeller shaft to the driving one of the first and second drive gears after the rheological fluid is used to spin up the propeller shaft to the appropriate speed.

Exhaust System For A Marine Vessel

View page
US Patent:
8403717, Mar 26, 2013
Filed:
Aug 24, 2010
Appl. No.:
12/862522
Inventors:
Brian R. White - Stillwater OK, US
Terry D. Axton - Stillwater OK, US
Keith S. Ducotey - Stillwater OK, US
Assignee:
Brunswick Corporation - Lake Forest IL
International Classification:
F01N 3/04
B63H 21/00
B63B 35/73
US Classification:
440 89B, 440 89 R, 440 89 E
Abstract:
A marine propulsion system has an exhaust conduit conveying exhaust gases from an internal combustion engine. The exhaust conduit has a dry portion and a wet portion located downstream of the dry portion. Cooling fluid enters the exhaust conduit to cool exhaust gases flowing through the wet portion. A bypass conduit is connected to the exhaust conduit and conveys a portion of the cooling fluid away from the dry portion to thereby decrease reversion of cooling fluid into the dry portion.

Marine Exhaust Elbow With Condensation Reducing Water Circulation System

View page
US Patent:
7699675, Apr 20, 2010
Filed:
Jan 20, 2009
Appl. No.:
12/356108
Inventors:
Loren T. Powers - Stillwater OK, US
Keith S. Ducotey - Stillwater OK, US
Christopher J. Luckett - Stillwater OK, US
Assignee:
Brunswick Corporation - Lake Forest IL
International Classification:
B63H 20/24
US Classification:
440 88J, 440 89 B, 440 89 C
Abstract:
An exhaust system of a marine propulsion device is provided with a bifurcated cooling passage in its elbow structure in order to limit the effect of cold water being disposed in thermal communication with exhaust gas passing through the elbow structure. This thermal communication between a stream of cold water and exhaust gas passing through the elbow structure is minimized in order to reduce the likelihood that water vapor will condense out of the stream of exhaust gas as it passes through the elbow structure. An obstruction, or water dam, is used to bifurcate the coolant chamber within the elbow structure while allowing passage of coolant through the obstruction.
