Abstract: A converter converts an existing bulk bag unloader to a bulk cargo receiver that eliminates the use of bulk bags. The converter enables the unloader to receive a continuous feed of bulk cargo without any interruptions such as those needed to unload emptied bulk bags and reload the unloader with full bulk bags.

Abstract: A long fiber extrusion apparatus applies a polymer melt to a length of fiber using a die and an extruder where the length of fiber is directed to the die through a glass tube. The transparency of the glass tube enables viewing of the fiber as it is directed through the glass tube to monitor for any difficulties or problems encountered by the fiber passing through the glass tube. The glass interior surface of the glass tube reduces friction between the fiber and the glass surface and thereby reduces abrasion of the fiber and dust produced from abrasion of the fiber inside the glass tube.

Abstract: A bulk cargo blending hopper has a hollow interior volume that is selectively communicated with a source of vacuum pressure. A first conduit has a first end that is connected to the housing of the hopper and communicates with the interior volume of the housing of the hopper. An opposite second end of the first conduit is configured for communication with a source of bulk cargo that is separate from the hopper. A second conduit has a first end that is also connected to a portion of the housing of the hopper and communicates with the interior portion of the housing. A second end of the second conduit is also connected to a portion of the housing of the hopper and communicates with the interior volume of the housing of the hopper.

Abstract: A modular plastic extrusion apparatus has several component parts. The design of the integration of those parts into a modular extrusion system is unique. Said design allows for rapid assembly, testing, disassembly and placement into production of extruded plastics. This modular plastic extrusion apparatus has several components with replaceable counterparts that, after one product line of a particular color has been extruded by the apparatus, enable the component parts used to produce the particular color extrusion to be removed from the apparatus and replaced with their clean counterparts to continue producing an extrusion product line of a different color while the removed components are cleaned off line.
