Abstract: THIS invention relates to a method of disposing of residues from the comminution and processing of ores. The method includes the steps of classifying the processing residues into a water permeable sand fraction and a tailings fraction and depositing the tailings fraction and the sand fraction to form a multilayer structure contained by at least one containment wall (14) with the sand fraction forming continuous channels (12) through the tailings fraction (10) to allow water contained in the tailings and sand to flow by gravity, through the sand channels, to water discharge points (16), and recovering the water (18) from the water discharge points.

Abstract: An adjustable seal that is kinematically linked to a container to provide a complete seal of the container opening and to allow easy access to contents therein. The seal includes a lid portion and a sealing means, as well as a lever and a yoke, which are kinematically linked together via a plurality of pivot points. The seal also comprises a spring system having a springfront, a spring rear, and a spring, and the spring system is likewise mechanically connected to the other components. Due to this kinematic linkage, the closure is moveable among different positions to provide various degrees of access to and from the container via the container opening. As a result, the sealing system of the present invention protects against spillage and splash by completely sealing the container opening, as well as provides easy access to the contents of the container.

Abstract: A collapsible wingback chair that includes a seat base portion and to which is secured a lower portion of a pair of side wings that include upper portions that are movable relative to a chair back that is pivotally mounted so as to be movable between an upright position when the chair is in use to a folded position in overlaying relationship with the base with the upper portions of the side wings also being folded relative to the base to thereby form a compact configuration for handling, shipping and storage. The side wings are selectively secured to the chair back when the back is in a raised position to thereby permit use of the chair in a conventional manner.

Abstract: An apparatus for conditioning mammalian blood for subsequent use in a medical procedure includes a cabinet having a secure environment and a door providing the only access to the environment. An input system transports a blood charge from a source to the cabinet and a flask is removably contained in the secure environment and coupled to the charge input system to receive the charge. Stressors are coupled to the cabinet and positioned for operation to create a conditioned charge in the flask. An output system is coupled to the flask and includes a receiver for the conditioned charge. The apparatus includes an automated control system operable upon closing the door to lock the door and to then condition the charge, and to then cause the charge to move from the flask to the receiver.

Abstract: An electric seat assist device having a seat pivotally secured to a base. One or more cam members extend in generally opposing relationship from the seat and base and are seated on one or more sets of rollers which are linearly adjusted to raise and lower the seat by a drive member which is pivotally mounted relative to the base and the rollers of the seat assist device. Stroke detectors are used to control motor drivingly connected to the drive member after being activated to initiate raising or lowering of the seat.

Abstract: This invention provides in an article of manufacture having a fabric support surface: a fabric support surface; a peripheral frame for the support surface, said frame having opposed base sections and opposed flexible arch sections extending between the base sections; and arch flexing means for moving the opposed base sections towards each other to flex the arch sections outwardly of each other and for maintaining the base sections from separation whereby to tension the fabric support surface between the arch sections and form a firm support for weight placed thereon and to restrain the effect of weight thereon from moving the opposed arch sections inwardly of each other.

Abstract: A system is provided for the automated imaging of a succession of microscope slides (S). The slides are mounted in carriers and loaded into cassettes. Slide carriers from a first cassette in a slide loader (2) are ejected from the cassette into a loading station and thence moved by an actuator onto a stage beneath a microscope objective (6) which images a sub-area of a circular sample area on the slide onto an imaging sensor (10) whence images are digitized and stored. The stage (4) is conjointly rotated by a motor (22) as a carrier (24) for the stage is moved linearly, so as to execute a spiral scan of sub-areas of the sample area which sub-areas are successively imaged using a strobe lamp (12) to illuminate the sample area at intervals during the scan determined by signals from an encoder (25). A preliminary scan, which may be in an opposite direction along the spiral, may be used to obtain, for a focus actuator (18), focusing data used during the scan.
