Abstract: A regulator system for handling the flow of gases and fluids between a nutrient and medication supply system and an implanted g-tube using an intermediate chamber to cause phase separation of any gases entrained within the supply stream or backflow from the g-tube. The chamber is vented to allow escape of the separated gases while acting as a temporary reservoir retaining any solids or liquids for feeding into or return to the stomach through the g-tube.

Abstract: Rectangular construction studs are provided with a plastic or polyethylene extrusion resin skin by extruding the plastic onto the manufactured core of the stud through a die which has been constructed to provide a substantially uniform rate of feed of extrusion materials throughout an entire flattened rectangular oblong enveloping prismatic and conforming cavity defined in the die which completely and prismatically circumscribes a rectangular core member, which is being disposed and translated through the die from a feed position in the die to its extrusion exit ports. The uniform volume feed rate is achieved through the use of a plurality of feeding risers communicating between a supply runner and an extrusion channel in the die.
