Abstract: An improved method and apparatus for water harvesting wherein a separator grating is lowered into the water to hold trash below the harvestable berries that are then caused by their buoyancy to rise through the immersed separator. The berries thus separated from the debris are gathered in various ways, such as the conventional loading via a conveyor, removing the berries by lifting the separator grating after the apertures of the separator have been reduced, or using a second grating with smaller openings. The method can be carried out in a reciprocating cycle or using a continuous rotating movement of the separator that might be part of a band scoop, mechanically powered scoop, or rolling harvesting apparatus. Provisions are also provided to simultaneously remove the debris separated from the berries from the flooding water. The method and apparatus might also be used in cleaning the harvest in a flooded tank on the dike.

Abstract: A removable element for a tool system is disclosed. The element may be used in a system of slide-on tools and adaptors that eliminates a two-handed operation for changing tool bits. The element comprises at least one prong located at one end at a selected distance and substantially parallel to an axis of rotation of the tool system. The prong is adapted to slidingly fit and rotationally abut with another element of the tool system to transfer rotary motion between the elements, and means are provided for supporting a tool bit on the axis of rotation at the other end of the element from the prong.
