Embodiments of a printed security mark and a process are disclosed.

Printed security mark

A dispensing apparatus, which is capable of delivering precise quantities of a liquid product less than one mmin 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.

Mixing rotary positive displacement pump for micro dispensing

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.

Viscoelastic liquid flow splitter and methods

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.

Article of manufacturing including a two-part adhesive with a fluorescent dye and method of making

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.

Material dispenser having a positive shutoff mechanism

An article of manufacture including a first adherend and a two-part adhesive mixed and dispensed on the first adherend, wherein the first part of the two-part adhesive includes a first fluorescent dye. The article of manufacture further includes a second adherend in contact with the two-part adhesive.
