Marine propulsion August list of inventions 08/08

20080207065 - Boat propulsion apparatus: A boat propulsion apparatus is constructed such that an operation mode can be switched to a reverse mode and an amount of an output can be set by an easy operation without a complicated structure and further in which a main body of the propulsion apparatus can be locked to... Agent: Yamaha Marine Kabushiki Kaisha C/o Keating & Bennett, LLP

20080207066 - Marine propulsion system and method of operating the same: A propulsion system for a marine vessel includes a first electric machine coupled to a first drive shaft configured to provide propulsion to the marine vessel, and a second electric machine coupled to a second drive shaft configured to provide propulsion to the marine vessel, in a first mode of... Agent: John S. Beulick (12729) C/o Armstrong Teasdale LLP

20080200079 - Separated electric motor assisted propulsion for human-powered watercraft: A propulsion system for hybrid electric watercraft for personal enjoyment that incorporates human power with electric motor assistance, energy storage and optional solar power to achieve increased watercraft speeds and/or reduced pedaling effort. Control electronics enable operator-adjustable electric motor assistance to the propulsion, thereby providing flexible pedal cadences and efforts... Agent: Patrick Lee Jansen

20080200080 - Steering system for outboard motor: A swivel bracket of an outboard motor pivots about an axis of a tilt shaft disposed at a front end of the bracket unit and extending horizontally in a vertical plane to adjust a tilt angle and a trim angle of the outboard motor. A steering system for the outboard... Agent: Knobbe Martens Olson & Bear LLP

20080200081 - Vessel propulsion: The instant invention is a shroud/keel/rudder combination for use on a engine driven marine vessel having a vented tunnel propulsion system. The combination produces acceptable acceleration, minimal loss of speed, resistance to weed entanglement and optimized steering, in both forward and reverse, especially when used with surface piercing propellers.... Agent: Mchale & Slavin, P.A.

20080200082 - Jet pumping device: A propulsion or pumping device which includes two counter-rotating shafts (3, 4) each carrying at least one impeller (7, 8), wherein each impeller (7, 8) can deflect by a predetermined amount in directions substantially perpendicular t to the longitudinal axis of the shaft (3, 4) on which the impeller (7,... Agent: John Alexander Galbreath

20080194155 - Marine engine assembly including a pod mountable under a ship's hull: The marine propulsion set (1, 1′, 1″) comprises: at least one pod (2) that is mechanically connected to a support strut (3, 3′, 3″); a propeller (4) that is situated at the aft end of the pod and that has at least two blades (14); and an arrangement of at... Agent: Abelman, Frayne & Schwab

20080194156 - Marine bifurcated bottom ship: The present invention relates to improving the structure of the ship by means of fitting plural screws in series on the identical shaft generated by the diesel engine to augment the velocity in proceeding operation and bifurcating the bottom of said ship to reduce the water pressure on the prow... Agent: Yoshioki Tomoyasu

20080194157 - Clutch mechanism of an outboard motor: A clutch mechanism of an outboard motor includes a forward gear and a reverse gear that are always driven in opposite directions by a drive shaft driven by a drive system, and a dog gear disposed around the output shaft. The forward gear, the reverse gear, and the dog gear... Agent: Yamaha Marine Kabushiki Kaisha C/o Keating & Bennett, LLP

20080194158 - Marine reversing gear assembly: The present invention provides a marine reversing gear assembly, wherein a manual directional control valve 7a and an electromagnetic directional control valve 7b for a forward/reverse directional control valve 7 for hydraulic oil supply circuit 10 have a common structure of an oil line joint surface for the hydraulic oil... Agent: Posz Law Group, Plc
