Abstract: A downhole brush tool (10) includes a tool body (12) having a brush supporting portion (11, 13) on the tool body between upper and lower stops (20, 24, 26, 28). A split sleeve (32, 34) has a plurality of throughports (30) therein, and a plurality of brush elements (42) including a base member (44) and a plurality of bristles (46) extend from the base member. The base member is positioned within a cavity in the brush supporting portion of the tool body, and a stop surface (45) supported on the split sleeve engages a base member to prevent the brush element from passing radially outward.

Abstract: Clumps of dried fruit are separated into individual fruit pieces with reduced damage to the fruit itself by passing the clumps through an apparatus containing a rotating shaft from which robber-like resilient fingers protrude. As they rotate, the fingers pass between other fingers in the apparatus, and the combination exerts a force on the dried fruit clumps that varies with the degree of deflection of the fingers and hence with the sizes and resistances of the clumps.

Abstract: A reconfigurable set associative cache memory can be reconfigured from 2.sup.x way to 2.sup.y way set associative cache memory by effectively merging a predetermined number of least significant bits of the tag field of the main memory address with the line field of the main memory address. The effective merging is provided by logically merging least significant bits of the tag field with a reconfiguration designation. As a result, Y-X+1 different configurations of cache memory can be obtained using the Y-X least significant bits of the tag field merged with the cache memory address.

Abstract: A method and system are provided for separating low and high density particles from a mixture thereof. A foam is continuously generated and carried on the outer surface of a horizontal drum. The mixture of particles is deposited on top of the foam surface near the apex of the drum so that the dense particles fall through the foam while the less dense particles are supported on the upper surface of the foam. A first blade is provided to shear the upper surface of the foam and remove the less dense particles. A second blade engages the surface of the drum downstream from the first blade to remove the relatively dense particles. The system finds particular use in separating raisins (dense particles) from waste materials associated with raisins (less dense particles).
