  • Patent number: 8319359
    Abstract: A device for a wave-powered generator which is provided with at least one energy generator and lines for transferring energy to a consumer, the wave-powered generator comprising a main module provided with a running rod which is substantially vertical in its longitudinal extent, several supporting devices arranged around a portion of the running rod and arranged for sliding or rolling movement on surface portions extending in the longitudinal direction of the running rod, at least one sheave which is arranged to roll on the running rod, and transmission means which are arranged to translate the rotating motion of the at least one sheave into rotation of the drive shaft of the at least one generator; and a first float which is floatingly disposed in an area affected by waves and which is connected to the running rod by a primary driving line substantially of tensile strength.

  • Patent number: 5695012
    Abstract: A deep subsoiler (50) consists of a plurality of carriages (58) abreast on a frame (52) and a plurality of shanks (60) mounted on each of said carriages. The mounting for each of said shanks provides a fail-safe mechanism consisting of a pair of rosettes (72) with shear-bolts (86). Said rosettes enable the operator to minutely set an angle of attack for each shank tip (P37). Said carriages align parallel with a direction of travel. Each shank on the carriage functions at an increasing depth which provides a staged sequence with a shortest shank (60c) in a forward position. Theory and tests indicate a draft reduction using staged shanks. Said tips for these shanks produce larger voids in the subsoil and increase the flow of subsoil to the surface. Staged shank standards (P40) cut narrower grooves in the surface that inhibit rivulets. The larger voids hold more water and organic material and this material adheres better to the surface.

  • Patent number: 5520253
    Abstract: A method employing a basic structure and a collection of components to improve efficiency in caring for laws and gardens. The basic structure comprises a single engine, speed reducer, and transmission mounted on a frame with handle bars and controls. The components make up a collection of tines, wheels, blades, rollers, plows, racks and mounting parts. The operator mounts selected components on the basic structure to create a custom ramification for accomplishing a specific task. The specification describes eighteen applications. Eight apply to common tasks of tilling, grading, removing snow, shredding, edging and mowing. The ten remaining apply to new methods for wet lands tilling, hard ground tilling, rolling, aerating, dethatching, scooping, lifting, cross country transporting, and automatic mixing and separating. A primary advantage of the method lies in a consolidation that reduces costs for capital outlay, maintenance, storage, and transportation of walk behind equipment.
