Abstract: The Prentice Wind Engine will operate 100% from “wind power” from any direction to produce both air pressure as well as hydraulic pressure at the same time to work together to generate electricity. In the case of the Prentice Wind Engine, assuming that the wind is coming from the north direction, panel #1 is facing north in the closed position and receives the full force from the north wind. As it rotates, the wind spills out and air and gravity push the panel away from its based hinged position and in doing so, produces two functions, wind force from its rotation and pressure force from the hydraulic cylinder. As it proceeds through the 360° circle it gradually “feathers” back to its first closed position, ready to repeat the sequence, and the other wind panels follow the same sequence. Also, these units can be stacked one above the other to function as one unit.

Abstract: The shredder of the instant invention includes a housing for receiving material to be shred and an arbor carrying plural teeth thereon mounted in the housing. An anvil is provided, having plural grating members, interspersed with the teeth on the arbor, to shred material which is introduced into the housing. The teeth are fixed on the arbor in a helical pattern with each tooth being angularly displaced with respect to the next laterally adjacent tooth.
