Abstract: A polymerization reactor having a hollow stirrer drum which is an elongated drum having apertures therethrough with paddles extending across the apertures. The stirrer drum is concentrically disposed about an elongated source of gamma radiation which serves as the energy source for a polymerization reaction of material introduced into the reactor. The stirrer drum divides the reactor into two concentric and approximately equal volumes, one internal of the stirrer drum and one external of the stirrer drum, with the material being stirred and inter-mixed between the two chambers through the paddle apertures by rotation of the stirrer drum.

Abstract: A flat-bottom plastic bag produced from an extruded length of gusseted and thermoplastic material including the steps of sealing and severing a length of such material to provide a closed bottom; folding the upper portion of each gusset inwardly toward the center of the bag to create triangular portions at the bottom of each gusset, the bottom corners of the bag tapering inwardly with the taper being determined by the outer leg of each triangular portion; opening the folded gusset portions to a flattened position, each triangular portion being folded simultaneously along a median line and the inwardly tapered bottom configuration of the bag being retained; folding the tapered bottom portion of the bag upwardly toward the front of the bag thereby creating a transverse fold line extending from edge to edge of the bag, the height of this folded portion being substantially identical to the height of the folded median line of each triangular portion, the height of this median line being substantially identical to the depth or width of the gusset; and opening said upwardly folded portion, for packing and/or shipping purposes, to a plane contiguous to that of the remainder of the bag. The invention also contemplates the novel bag produced by the above method.

Abstract: An elongated radioactive source of gamma radiation is used in initiating polymerization in a polymerization reactor. The elongated source rod is axially movable within the reactor so that its end terminates at any desired location within the reactor which will have polymerization processes initiated. This in turn adjusts the production rate of the reactor. A servo system is connected to drive the radioactive source rod to maintain a constant production rate. The radioactive rod may be divided into two or more parallel rods which are independently movable in order to provide any desired profile for the intensity of the radiation source.
