Abstract: A fluid turbine comprising a rotor, having an axis of rotation, comprising at least two rotor blades disposed at a radius from the axis of rotation, each rotor blade having a pitch axis and a variable pitch angle. The fluid turbine comprises a mechanism operable to control the pitch angle of at least one rotor blade about its pitch axis and to vary the pitch angle of the rotor blade between various pitch angles as the blade moves radially about the axis of rotation of the rotor.

Abstract: A fluid turbine comprising a blade pitch control mechanism comprising a cam and at least one rocker assembly, each rocker assembly comprising a rocker arm operable to pivot about an axis of rotation, the blade pitch control mechanism being operable to control the pitch angle of at least one rotor blade about its pitch axis and to vary the pitch angle of the rotor blade from a first pitch angle at a first circumferential location about the axis of rotation to a second pitch angle at a second circumferential location about the axis of rotation.

Abstract: A fluid turbine comprising a rotor, having an axis of rotation, comprising at least two rotor blades disposed at a radius from the axis of rotation, each rotor blade having a pitch axis and a variable pitch angle. The fluid turbine comprises a mechanism comprising an actuation rod secured to an internal portion of each rotor blade, operable to control the pitch angle of at least one rotor blade about its pitch axis and to vary the pitch angle of the rotor blade between various pitch angles as the blade moves circumferentially about the axis of rotation of the rotor.

Abstract: A telescoping handle assembly for luggage or other luggable items. A telescoping handle assembly is provided that includes a primary handle and a secondary handle. The secondary handle provides at least one gripping surface that, when deployed, may extend in a direction generally parallel to a direction that a traveler may move when transporting an item attached to the secondary handle from one location to another.

Abstract: An adapter for attaching to the edge of a door, such as a freezer door, to permit coupon dispensers, display devices and the like to be mounted to the edge of the door. The adapter is held in place with a clamp that bears against the door handle. The adapter includes a mounting plate perpendicular to the door so that a coupon dispenser or other display device can be mounted substantially parallel to the door. The mounting plate includes a portion of a price rail so that the same coupon dispensers and mounting brackets used with grocery shelves may also be used with the present invention. The price rail may be a separate piece that is welded to the mounting plate or formed from the same piece of material as the mounting plate.
