Abstract: ROTOR FOR AN AXIAL FLOW ROTARY SEPARATOR        Abstract of the Disclosure Material control elements carried by the rotor of an axial flow rotary combine separator include inclined blades as well as conventional rasp bars.  The inclined blades take various forms but common features include their downstream inclination, (that is in the direction of the axial movement of crop material in the separator) and having a frontal working edge athwart the direction of rotation to engage crop material and deflect or urge it down-stream.  The orientation and configuration of the blades results in their working edges being their dominating material control feature while the inclined surfaces have a subordinate role in material control, the actual effect of the surfaces depending on the orientation of their line of slope with respect to the rotor axis.

Abstract: STEAM SEAL OF BAG PLY                 Abstract of the Disclosure A steam seal machine and process is disclosed to seal together the two contiguous edges of an inner heat sealable ply in a multi-ply tubular bag form.  The bag forms are conveyed transversely to their length by a first continuous conveyor and then by an intermittently operating conveyor into an openable steam chest.  The second conveyor stops, and the steam chest closes so that it envelops the open mouth of the bag form.          Steam is admitted to the steam chest through a valve and this steam penetrates the open end of the multi-ply bag form to seal together the contiguous edges of the heat sealable ply.       In this way the steam need not penetrate through several layers of kraft paper or other reinforcing plies.  The steam valve is closed, the steam chest opens and the second conveyor restarts to convey the bag form beyond the steam chest so that a part of a successive bag form may enter the steam chest.  This part may be the top, bottom or side of the bag form whereat the heat sealable ply is being sealed.

Abstract: ABSTRACT           A fractionation process wherein a fractionation column is maintained at a subatmospheric pressure through the use of a stream-jet ejector.  Water drawn off the over-head receiver of the fractionation column is vaporized by indirect heat exchange to form the moderate pressure steam charged to the ejector.  The effluent of the ejector is passed through a condenser, and the resultant condensate is recycled to the overhead receiver by admixture with the overhead vapor stream of the fractionation column.  The disposal of hydrocarbon-contaminated aqueous overhead liq-uid is thereby minimized.
