Abstract: A vertical axis wind turbine wherein the blades of the rotor section of the wind turbine comprise at least sections wherein the blades have a non-linear configuration in the “z” axis. In a preferred embodiment, the blades of the rotor section have a linear trailing edge with a non-linear, and preferably helical, surface configuration. This particular design allows the blades to provide both a rotational force and a positive or negative lift component. Further, the blades define an open area in the center of the rotor section through which air flow can pass in order to create a vertical vortex of air. As such, a more efficient vertical axis wind turbine provided.

Abstract: A substantially rectangular reinforcement assembly for concrete castings, having a longitudinal axis and a transverse axis. The assembly comprises a frame, a first set of longitudinal runners, a second set of transverse runners, and a third set of transverse runners. Each individual runner has two short ends, and each short end has a frame holding means. The runners are arranged in a hatch pattern, where the longitudinal runners are arranged substantially perpendicular to the transverse runners. The frame comprises a first leg member, a second leg member, and a shoulder member. The first leg member has a plurality of through holes and the second leg member has a corresponding number of through holes, which are substantially concentric with the corresponding through holes of the first leg member.

Abstract: A gasoline motor powered spreading apparatus for use with vehicles equipped with articulating dump boxes is described. The spreading apparatus includes a hopper assembly, a spinner, a mounting platform for a gasoline powered motor, a mounting platform levelling system, and a multiple output gearbox. The entire assembly is configured to substitute directly for most conventional vehicle tailgates. The levelling system ensures that the motor (platform) is level through the full range of articulation of the dump box in order to provide efficient operation of a gasoline powered motor. The multiple output gearbox provides variable gear ratios to power peripherals such as the spinner and the auger. The gasoline powered motor as well as the peripherals may be manipulated remotely from the driver's area of the vehicle. The apparatus is easily installed or removed and requires limited modification to the vehicle.

Abstract: A vehicle-mountable push broom has a generally horizontal frame provided with a plurality of transverse downwardly-opening generally C-shaped channels, and a plurality of removable bristle strips positionable one in each channel. Each strip has a holder specifically configured to be accommodated within the channel, and a plurality of bristles mounted in and extending downwardly from the holder. The strips are loosely held within the channels, such that the holders are permitted to rock within the channels, for example through an angle generally in the range of 10 to 20 degrees.

Abstract: A salt spreader mounting assembly that attaches to the rear of a utility vehicle such as a conventional pick-up truck is described. The salt spreader mounting assembly includes a frame which attaches to the vehicle, and pivoting connections between the frame and the vehicle such that the frame can swing horizontally thereby permitting access to the rear of the vehicle, without interference with the tailgate. The frame supports a compatible salt spreader/hopper unit. The assembly allows a combination spreader/hopper to be swung away from the vehicle from at least one of its sides, thereby allowing direct access to the rear cargo area via the tailgate. The assembly is easily installed or removed and requires limited modification to the vehicle.
