Patent CA-2142747-A1 (CA)
Inventor: KURYLUK MICHAEL H
IPC: B07B7/08
Filed: 1995-02-17
Abstract: A method and apparatus for separating from a mixture materials having different specific gravities which can operate in a continuous manner and can separate particles of materials of non-uniform grain size. Water or other fluid is passed upwardly through an apparatus having an upper funnel in which is disposed a rotatable agitator having vanes or paddles which pass close to riffles on the wall of the funnel. Material to be separated is fed into the funnel and the upward flow of fluid is adjusted so that material of low specific gravity is carried up the funnel to an overflow discharge. With the agitator rotating, fine particles of the material to be separated and having a specific gravity higher than a certain figure are captured in "dead-zones" created behind the riffles and move down through the fluid to a discharge tube. Larger particles of the material to be separated move down through the upward flow of fluid to the discharge tube. The supply of fluid is periodically momentarily interrupted to eject material collected in or just above the discharge tube.

Title: Solution pumping system for maximizing output while minimizing pumping pressures
Inventor: OGDEN JOHN E
IPC: F04B43/04
Filed: 1993-12-10
Abstract: A solution pumping system (10) is dis-closed which is embodied as a disposable pump cassette (12) including a self-contained positive displacement  pump, and an associ-ated pump driver (14) including a reciproca-ble pump piston (36) for driving the pump of the cassette. This system is particularly suited for use in compounding in preparation of parenteral solutions for administration to patients.

Title: Packaging arrangement
Inventor: EDWARDS RUSSELL JAMES
IPC: B65B11/50
Filed: 1995-06-08
Abstract: A method and a packaging arrangement for packaging products, such as contact lenses, in packages such as blister pack. The arrangement has a movable support base having on its upper surface a plurality of substantially identical support pallets, spaced equally apart along the movable support base. Each of the pallets is particularly designed to support and align an array of individual package bases. The support base is sequentially moved through substantially equal incremental movements, with stops between each sequential movement, such that each support pallet with an array of individual package bases thereon is sequentially stopped at spaced stations in the packaging arrangement. At a first station, a loader loads an array of package bases in the support pallet then at the first station. At a subsequent foil placement station, a placer unit places a sheet of laminated covers over the array of package bases. At a still subsequent heat sealing station, a heated seal head heat seals the laminated covers to the package bases. At a subsequent unloading station, an unloader unloads the sealed packages from the packaging arrangement for subsequent processing.
