Abstract: A self-contained, continuous flow pasteurizer is herein disclosed. Such a pasteurizer comprises a first tank and a second tank interconnected by a pasteurization conduit. A single pump pumps fluids from the first tank to the second tank at a predetermined flow rate. Fluids are heated to their desired pasteurization temperature in a first section of the conduit and are held at this temperature while flowing through a second section of the conduit. Fluids not reaching the desired pasteurization temperature do not pass into the second section of the conduit but are recirculated back to the first tank by a recirculation valve and conduit connected between the first tank and the pasteurization conduit. A third section of the conduit passes through a cooling structure so that the fluid flowing in the conduit will be cooled down from its pasteurization temperature before being deposited in the second tank.

Abstract: Molding material consisting of resin coated reinforcing fibers in a molten mass of resin and fibers is prepared at a molding site for controlled supply to a molding machine. A conveying device, such as a pair of pinch rollers, serves to pull fibers from supply spools through guide orifices of a coating die having a chamber within which the fiber is coated with molten resin. Further impregnation of the fibers with resin takes place in the conveying device, which also develops pressure on its output side serving to push the mass of hot resin and fiber into a receiving device for movement to a molding machine. The receiving device may be the feed screw for an injection molding machine or simply a plate movable to and from a compression molding machine. The fibers may be cut into predetermined lengths by a cutting device positioned downstream of the aforesaid conveying device.
