Abstract: An improved method of shrink fit assembly of two components increases resistance to torsional and/or axial loads without the need for a separate key element. Use of a roughened surface, in combination with a softer deformable material, creates a keyed type interaction at the contact areas of the shrink fitted components. One of the shrink fitted components may include the softer material, though intermediate layers and sleeves can be used.

Abstract: Comminution apparatus is described which is tailored for the processing of green, soft, and fibrous waste. Inner and outer comminution drums bear projecting macerating features which can progressively interact to provide a shearing action on material on waste within the outer comminution drum. Screening apertures on the outer comminution drum allow for the exit of comminuted material.

Abstract: A rotary flow divider, particularly for use in hydraulic circuits for applications such as dividing the output of a hydraulic pump between several differently (non-equally) loaded devices. Includes a central distributor which channels fluid from the pump to outlet ports, and an outer housing with a plurality of distribution ports (associated with different loaded devices). Repeated alignment and closure of outlet and distribution ports in a sequential type manner distributes fluid to the different devices. Such port alignment and closure is achieved by movement of the distributor and housing relative to each other in a rotational and/or linear manner, though an intermediary moving shutter device or sleeve may be used instead. Such an intermediary shutter device or sleeve may also be configured as a repositionable control sleeve to modify the nature of distribution of fluid when it is secured in different positions.
