Abstract: Various embodiments of a power wand are provided. The power wand may be utilized with an awning assembly including a motor to power and direct rotation of the motor. Therefore, the power wand will electrically drive and direct extension and retraction of the awning assembly. The power wand may be a portable hand-held device which provides battery powered operation of the awning motor. The use of the wand therefore eliminates the connection of awning wiring to the electrical system of the recreational vehicle (RV) or other mobile or fixed structure to which the awning may be mounted.

Abstract: An involute gear is disclosed. A circular base has a surface that includes an inner region and an outer region. A gear tooth extends outward from the outer region of the surface. A shape of the gear tooth is defined by a varying cross-sectional involute profile. Starting from a first involute profile that is in a plane parallel to the surface of the circular base and extending outward from a center of the circular base, each location on the first involute profile is rotated about a corresponding axis while traversing a path defined by a corresponding imaginary ray extending from the center of the circular base to that location in the first involute profile. The corresponding axis is tangential to an imaginary circle that encompasses the inner region of the surface and is perpendicular to the corresponding imaginary ray.

Abstract: A drive assembly has two bevel gear angle drives (9, 10) for driving an agricultural implement (2) via a tractor power take-off shaft. The assembly has a pivot bearing (11) which effects a pivotable connection between the two bevel gear angle drives (9, 10).
