Abstract: A fluidized bed reactor system which utilizes a fluid phase, a retained fluidized primary particulate phase, and a migratory second particulate phase. The primary particulate phase is a particle such as a gel bead containing an immobilized biocatalyst. The secondary and tertiary particulate phases, continuously introduced and removed simultaneously in the cocurrent and countercurrent mode, act in a role such as a sorbent to continuously remove a product or by-product constituent from the fluid phase. Means for introducing and removing the sorbent phases include feed screw mechanisms and multivane slurry valves.

Abstract: For a copier with a document handler ejecting original documents after copying into a document collection tray system, a plural mode document collecting system is provided for collecting and restacking different forms of documents, including both conventional sheet documents and computer form web being re-fanfolded, with a single tray movable between two different operative tray mounting positions in a substantially vertical track, with respective retentions at a first tray position adjacent the document output of the document handler for collecting conventional sheet documents, and a second tray position substantially below the first tray position for re-fanfolding computer form web. Also disclosed are stationary fanfold restacking assist members operative in the second tray position mounted intermediately of the first and second tray mounting positions and mutually adapted with the tray to allow the tray to be moved past.
