Abstract: IMPROVED FLOTATION APPARATUS                FOR CONCENTRATION OF MINERALS                 ABSTRACT OF THE DISCLOSURE    The invention relates to the concentration and benefication of particulate matter by froth flotation and in particular to improvements in hydraulic-pneumatic flotation apparatus which contributes to efficiency of operation.  Such apparatus employs a constriction plate which separates vertically arranged flotation and aerating compartments.  A discharge duct may be used to extend through the aerating compartment and to open through the constriction plate centrally thereof.  Orifices in both the constriction plate and the discharge duct are in communication with the aerating compartment to provide a uniform dispersion of air bubbles in the flotation compartment.  To prevent build-up of non-float fraction on the constriction plate, the latter may be dish-shaped toward the discharge opening.          In an alternative embodiment, the discharge duct is omitted and the constriction plate is conically shaped with the apex uppermost.     To minimize development of circulating currents, baffles plates may be used in the flotation compartment.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved method and apparatus for forming nonwoven webs by spinning filaments into a quench chamber where they are contacted with a quenching fluid, then utilizing the quench fluid to draw the filaments through a two-dimensional nozzle spanning the full machine width, and collecting the filaments as a web on a porous surface.  In contrast with the prior art, low motive fluid pressures can be used, and a non-eductive drawing means utilized to minimize air turbulence and the resulting filament entanglement in the drawing means while maintaining substantially constant cross machine filament distribution.          The apparatus and process reduce problems relating to filament breakage and spreading and result in increased productivity and improved web formation.  Other advan-tages include the ability to continuously spin highly pigmented polymer filaments and reduced hazards associated with high noise levels.

Abstract: ABSTRACT OF THE DISCLOSURE        A system for transporting a tray holding at least one specimen slide to and from the microscope. The tray includes index marker means and engagement means.  The system comprises an input station, indexing means at the microscope stage and an output station.  The input station includes a hopper to receive a stack of slide-carrying trays, a first carrier located within the hopper to carrying the trays out of the hopper and onto the microscope stage and feeding means for dispensing the trays from the stack to the first carrier.  The indexing means carries the tray to at least one predetermined index position on the stage and basically comprises a second carrier for moving the tray across the stage and a first sensor cooperating with the second carrier means.  The index marker means activates the first sensor to stop the second carrier when the index marker means is in a first predetermined position corresponding to the tray being in the predetermined index position.  The second carrier carries the tray horizontally from the predetermined index position to the output station.  The output station receives the tray from the micro-scope stage and dispenses it into a storage container and basic-ally comprises a tilt-table which is pivotable from a horizontal position to a vertical position.  The table pivots when the tray has reached a predetermined idle position thereon.  The opera-tion of the entire system is under microprocessor control so that inputing and outputing occur at the same time.

Abstract: ABSTRACT         The invention provides lifting apparatus for lifting, transporting and stacking shaped articles, e.g. I-beams, both quickly and safely, and in such a manner that the stacked articles occupy minimum space.  The apparatus has a cross beam rotatably supporting pairs of clamping jaws which extend from the lower surface of the cross beam. The pairs of clamping jaws are interconnected by alignment means which ensures that the jaws are all kept parallel to each other during rotation relative to the cross beam. Groups of shaped articles can thus be clamped by the jaws and lifted by the cross beam, so there is no need to stack the articles with spacer members therebetween, which is necessary when the articles are lifted by conventional cranes or forklift trucks.  Quick, safe and economical lifting, transportation and storage can thus be achieved.
