The wind-power-conversion mechanical efficiency of the invention is significantly improved over previous efforts, to the point that the invention can convert wind energy into electrical power at a price-to-performance ratio that competes with or surpasses existing alternative energy technologies.

First gear for use in a gear set including a second gear has a hub to which are attached a plurality of arms made of an elastic material. Each pair of adjacent arms defines a slot between them into which the arms may bend. The arms can deflect elastically in the plane as a cantilevered beam. Each arm has on the end thereof, a tooth for meshing with a tooth on the second gear to allow transfer of force between the first gear's tooth and the meshing second gear's tooth. A load distributor in contact with at least first and second arms distributes to the second arm at least a portion of force received by the first arm's tooth while the first arm's tooth meshes with a tooth on the second gear. In one embodiment, the load distributor comprises an insert within the slot between the first and second arms.

A roller traction drive system integral with a non-engine drive means and a clutch assembly in an aircraft drive wheel drive system capable of moving an aircraft autonomously on the ground is provided. The roller traction drive system is selectively activated by the clutch assembly into and out of actuating contact with the non-engine drive means to drive the aircraft drive wheel. Roller traction drive system components are made of materials designed to enable dry running and operation at the torques, drive means speeds, and reduction ratios required to actuate a drive means and drive a drive wheel for autonomous aircraft ground movement. Roller traction drive materials may be selected to maintain effective torque transfer between roller traction drive system components and the non-engine drive means as well as to minimize undesirable thermal expansion.

An apparatus for use in a cylinder machine having a shoe with a concavely-shaped pressure surface that forms a substantially mating relationship with a cylinder mould or sieve. The concavely-shaped pressure surface of the shoe increases the amount of wrap that a making fabric has on a cylinder mould or sieve thereby increasing the amount of friction generated between the making fabric and the cylinder mould or sieve. The increased friction results in an improved torque transfer between the making fabric and the cylinder mould or sieve.
