Platelets are collected from blood by delivering blood from a blood source to a centrifugal separator and operating the separator to separate plasma from the blood. The separated plasma is collected in a plasma collecting bag. After a predetermined amount of plasma has been collected in the bag, the plasma is circulated between the bag and the separator. That procedure is repeated at least once to build-up the amount of collected blood. Then platelets are collected by delivering additional blood...

An apparatus for collecting and forwarding encoded information includes a source of power maintained from the output port thereof to provide power to the source of encoded informations whereby a local subscriber is not required to supply power to such encoders via the AC mains to his premises.

A sheet collecting apparatus for collecting paper sheets, comprises a plurality of collecting chambers which are arranged to receive sorted bills through an insertion port, a shutter unit which is disposed to cover dispensing ports of all of the collecting chambers and is movable between a first position where all of the dispensing ports are closed and a second position where all of the dispensing ports are opened, and a drive section for driving the shutter unit in one of the first and second p...

The invention contemplates the provision of a double-shelled dust-collecting hood for a high-speed rotary cutting tool. The outer shell seals itself to the workpiece while the inner shell stands clear of the workpiece. The outer shell is open-ended so that the flow of air induced by a suction port within the hood enters at the unsealed end of the outer shell and reverses direction as it turns into the inner shell.

A mixture of particles of different materials is further comminuted by rubbing contact while moving at high relative velocity along a surface of a solid body to a substantially smaller size range during which the particles of different materials acquire a very high differential charge, and while bearing such high differential charge the particles of different material are entered into an electric field for efficient separation of particles of one material from particles of another material.

In a paper sheet collecting apparatus according to the present invention, paper sheets successively fed from a conveying path are guided and collected into a collecting chamber, held between vanes of a rotating vane wheel, is provided with a separator which can rock around the rotating shaft of the vane wheel and also move in the radial direction of the rotating shaft. In distributing the paper sheets, the separator is rocked through a predetermined angle and then moved radially, so that succeed...

A waste toner collecting apparatus includes a first cylindrical member for receiving a waste toner scraped off from a photosensitive member, and a screw conveyor housed by the first cylindrical member for conveying the waste toner. A first opening is formed at a downstream side of the screw conveyor of the first cylindrical member. A second cylindrical member is fitted onto an outer circumference of the first cylindrical member, and a second opening is formed thereon at a part corresponding to t...

A device for collecting sheets comprising a collecting tray and a conveyor roller for feeding sheets into the tray. The collecting tray comprises a baseplate having a distance between abutment surfaces which corresponds to a dimension of the sheets to be collected, preferably the length. The middle part of the baseplate is higher than the side parts. An abutment strip which contacts and stops the leading edge of a sheet fed into the tray is connected to an edge of the baseplate and has a surface...

A debris collecting apparatus includes a debris conduit (2) one end of which is an operating end (4) and the other end of which is a collecting end with a collecting bag (6) attached thereto. An impeller (8) discharges air into a straight part of the conduit. A switch arrangement is provided to switch the air flow between first "vacuum" flow in which air discharged from the impeller induces an air flow in the debris conduit (2) from the operating end (4) to the collecting end and a second "blowi...

A bottle opener for bottles having twist-off caps including a container having an end wall with an opening therein adapted for insertion of a bottle-mounted cap therein. A cylindrical member is connected to and extends into the container from the opening. The cylindrical member is open at the end thereof opposite the opening in the end wall and has a passageway adapted for passage of bottle caps through the cylindrical member and into the container. Longitudinal ridges on the interior of the cyl...
