Filed:

Sep 10, 2004

Appl. No.:

10/939010

Inventors:

Thomas Glenn Stephens - Grand Prairie TX, US

Assignee:

TGS Innovations, LP - Dallas TX

International Classification:

F02B 75/18
F02B 75/32

US Classification:

123 564

Abstract:

A power-generation device comprising at least one cylinder, at least one cylinder head, at least one piston and an output shaft, having a central axis having a fixed angular relationship to the central axis of the cylinder. A swash plate, having a first swash plate surface having a normal axis disposed at a first fixed angle to the central axis of the output shaft, is fixed to the output shaft. At least one connecting rod is connected to at least one piston. At least one follower is secured to the second end of a connecting rod. The first follower surface contacts, and conforms to, the orientation of the first swash plate surface.

Thomas G. Stephens - Grand Prairie TX, US

Assignee:

X Blade Systems LP - Dallas TX

International Classification:

F03D 9/00

US Classification:

290 55, 290 44, 290 54, 290 43

Abstract:

A wind driven generator includes a rotor disposed in a cylindrical duct and supported by a frame for rotation in response to wind flowing through the duct. The rotor includes plural circumferentially spaced paralleled rotor blades supported for rotation about a generally horizontal axis. Each blade is supported for pivotal movement to change blade pitch, angle of attack or camber as the rotor rotates. A pitch or camber control motor or self-governing wind vane mechanism is operable to move a circular cam to vary blade pitch or camber to control rotor speed. The duct is mounted on a mast having a base supported on a foundation for pivotal movement to face the wind for maximizing air flow through the duct. Electric power generators are connected to opposite ends of the rotor at respective power output or drive shafts.

Assignee:

X Blade Systems LP - Dallas TX

International Classification:

B64C 27/22

US Classification:

244 9, 244 121

Abstract:

A rotary wing aircraft is provided with longitudinally oriented counter-rotating rotors with circumferentially spaced variable pitch elongated rotor blades connected at their opposite ends to rotatable support rings mounted on the aircraft fuselage. Rotor downwash may be guided laterally and longitudinally by respective sets of moveable guide vanes. Propulsion may be obtained by an engine providing thrust and power take-off for driving the rotors. An auxiliary or second engine may be drivingly connected to the rotors.

A wind driven generator includes a rotor disposed in a cylindrical duct and supported by a frame for rotation in response to wind flowing through the duct. The rotor includes plural circumferentially spaced paralleled rotor blades supported for rotation about a generally horizontal axis. Each blade is supported for pivotal movement to change blade pitch, angle of attack or camber as the rotor rotates. A pitch or camber control motor, self-governing wind vane mechanism, or governing mechanism is operable to move a circular cam to vary blade pitch or camber to control rotor speed. The duct is mounted on a mast having a base supported on a foundation for pivotal movement to face the wind for maximizing air flow through the duct.

Stanley Josephson - Dallas TX, US
Thomas Stephens - Addison TX, US

International Classification:

G06F017/60

US Classification:

235/379000

Abstract:

A negotiable instrument payee authentication and identification method in which payee identification information is printed onto the negotiable instrument and maintained in a computerized database. When the payee presents the negotiable instrument for cashing, the identification information contained within the database is recalled and compared to the identification information contained on the printed negotiable instrument to ensure conformity.

Rotor downwash may be guided laterally and longitudinally by respective sets of moveable guide vanes. Propulsion may be obtained by an engine providing thrust and power take-off for driving the rotors. An auxiliary or second engine may be drivingly connected to the rotors. One embodiment includes rotors with lift or blade pitch angle control mechanism for changing the resultant lift forces for providing aircraft lateral movement and movement about a yaw axis. A wind driven power turbine includes a similar pitch angle control mechanism.
