Abstract: A replaceable auger assembly includes a body having at least one material inlet defined therein and an auger disposed within the body. The auger includes a helical portion disposed about a shaft portion and a positive shutoff mechanism. The positive shutoff mechanism is configured to selectively close the material inlet.

Abstract: A viscoelastic liquid flow splitter includes a flow splitter body having a first bore including a first bore outlet and a first bore inlet, and a second bore including a second bore outlet and a second bore inlet The bore inlets are substantially parallel to each other and the bore outlets diverge from each other at an angle. The flow splitter also includes a compression fitting having a first and a second tubular portion fluidically coupled to the first and second bore inlets where the tubular portions are configured to fluidically couple to a double barreled viscoelastic liquid dispensing syringe.

Abstract: An article of manufacture including a first adherend and a mixed two-part adhesive disposed on the first adherend, wherein the first part of the two-part adhesive includes a first fluorescent dye.

Abstract: A dispensing apparatus, which is capable of delivering precise quantities of a liquid product less than one mm3 in size, includes a drive mechanism, a housing made up of at least two input channels coupled to a chamber made up of a first portion and a second portion. First and second component liquids are delivered via the first and second input channels respectively to the chamber and the first and second input channels are disposed so that interaction is hindered between the first component liquid and the second component liquid in either input channel. At least one feed screw with a helical thread is disposed in the chamber such that when the at least one feed screw is rotated by the drive mechanism the first and second component liquids are mixed to form a liquid product and the feed screw rotation also discharges the liquid product from the chamber.

Abstract: A dispensing apparatus includes a ceramic body having a chamber and at least one inlet channel fluidically coupled to the chamber. The chamber has a first portion and an outlet portion. The dispensing apparatus also includes one or more feed screws having a helical thread disposed in the chamber. Rotation of the one or more feed screws urges a viscoelastic fluid in the chamber toward the outlet portion of the chamber.
