Wind Turbine For Driving A Generator

View page
US Patent:
20060222483, Oct 5, 2006
Filed:
Apr 3, 2006
Appl. No.:
11/396331
Inventors:
Donald Seiford - Winter Garden FL, US
International Classification:
F03D 7/06
US Classification:
415004400
Abstract:
The invention is an improved vertical axis wind turbine for driving a generator, and more particularly to such a turbine including a rotor having an improved rotor blade configuration for increased rotational speed and power output. The vertical axis wind turbine generator includes a rotor having a pair of disk-shaped end plates mounted in spaced parallel disposition for rotation about their common axis on a central shaft. A pair of rotor blades are mounted on and extend between the end plates in generally opposed relation to one another and are spaced from the central shaft. Each rotor blade has a generally spoon or ladle shape, including a first generally arcuate substantially semicircular segment, and a second generally arcuate segment curved in a reverse direction. The first segment has a radius R, and the second segment has a substantially longer radius in a range of 2R to 3R. The turbine also includes a stator consisting of a pair of end plates disposed generally parallel to and overlapping the rotor end plates. A plurality of stator vanes are disposed in an annular array around and adjacent to the rotor for concentrating or compressing the moving air mass, or wind, and for redirecting the wind into engagement with the moving rotor blades on one side of the turbine and for deflecting the wind on the opposite side in a conventional manner. This configuration effectively traps the air compressed by the stator vanes over a substantial angle of rotation of the rotor, thereby extracting more energy from the moving air mass. At the same time, as the rotor continues to rotate, the reversely curved second or “handle” segment of the ladle-shaped blade continues to direct the moving air toward the first segment, while air entering the rotor on the following side of the reversely curved handle portion is permitted to pass through the rotor without offering resistance to rotation.

Shaftless Radial Vane Rotary Device And A Marine Propulsion System Using The Device

View page
US Patent:
20060222526, Oct 5, 2006
Filed:
Apr 4, 2006
Appl. No.:
11/396919
Inventors:
Donald Seiford - Winter Garden FL, US
International Classification:
F04B 17/00
US Classification:
417405000
Abstract:
A radial vane fluid motor or pump has an open ended tubular rotor having a cylindrical outer surface rotatably mounted in a tubular stator having its inner surface contoured to provide successive portions of increased and decreased spacing relative to the rotor body. A plurality of elongated movable vane assemblies are mounted on and project outwardly from the rotor surface to continuously contact the stator surface. Bearings support the rotor within the stator, and seals are provided for sealing the space between the rotor and stator. Pressure inlets and exhaust ports are provided in the stator to permit the flow of pressure fluid into or out of the device. Mounting the vanes on the cylindrical rotor surface enables production cost reduction and simplifies maintenance. A conventional propeller mounted in the cylindrical rotor provides an improved shrouded propellor propulsion system for marine vessels. Mounting the system on a vessel for rotation about an axis perpendicular to the axis of the rotor enables steering of the vessel without use of a redder.

Paddle Wheel For A Ship

View page
US Patent:
52135284, May 25, 1993
Filed:
Apr 22, 1992
Appl. No.:
7/872253
Inventors:
Donald S. Seiford - Inver Grove Heights MN
International Classification:
B63H 104
US Classification:
440 90
Abstract:
A paddle wheel for propelling a water craft. The paddle wheel includes a plurality of oppositely disposed paddles which are rotatable with a supporting shaft. Each of the paddles are formed with side and end plates with a rounded portion between the outer edges of the sides. The bottom half portion of the paddles is filled with concrete and the upper half is filled with air or evacuated. Thus, the paddles remain in a vertical position as the paddle wheel rotates.

Watercraft Docking Mechanism And Method

View page
US Patent:
39555259, May 11, 1976
Filed:
Mar 13, 1973
Appl. No.:
5/340666
Inventors:
Donald S. Seiford - Inver Grove Heights MN
Assignee:
Twin City Shipyard, Inc. - St. Paul MN
International Classification:
B63B 2156
US Classification:
114235R
Abstract:
A docking mechanism for watercraft such as barges and the like which is readily secured to a mooring pile and is floatable, the mechanism including a driving apparatus which is engageable with and drives the watercraft and apparatus for effecting the driving engagement. A method of controlling the direction of travel of a watercraft such as barges and the like between particular points from preferably an on-shore control station according to which the driving apparatus of the docking mechanism mentioned above is controlled in its driving relationship to the watercraft.

Paddle Wheel Propulsion System And Improved Paddle Used Therewith

View page
US Patent:
20060189227, Aug 24, 2006
Filed:
Feb 23, 2005
Appl. No.:
11/062801
Inventors:
Donald Seiford - Winter Garden FL, US
International Classification:
B63H 1/04
US Classification:
440090000
Abstract:
A paddle wheel propulsion system includes a paddle wheel mounted for rotation about its horizontal axis for propelling a vessel, and for unlimited rotation about a vertical axis perpendicular to its horizontal axis for steering the vessel. The paddle wheel is also supported for limited vertical movement relative to the vessel. Reversible power means is provided for independently controlling movement of the paddle wheel about its vertical and horizontal axis and for elevating and lowering the paddle wheel. Improved paddles are concave on both sides to provide maximum efficiency in both direction of rotation about the horizontal axis.
