Liquid dispenser is for accurate and repeatable controlled delivery of water and thicker liquids. Calibration is in volume steps of 0.05 ml. Multiple units can be cascaded to deliver different liquids on a moment-to-moment basis. The liquid dispenser has three components; the control unit, the reservoir unit and the solenoid. The control unit provides precisely timed pulses to the solenoid. It also does communications, coordination and monitoring. The reservoir unit operates on about 20 lbs of air pressure. It supplies pressurized liquid from the bottle reservoir to the solenoid. The solenoid delivers precise droplets of fluid. The control unit does a large number of functions including pulse timing however, with the aid of a separate 24 volt power supply and solid-state relay, the reservoir unit and solenoid can be connected directly to a computer and operated without the control unit.

Liquid Dispensing Assemblies includes a liquid supply line that extends into an ejection spout located above a fill chamber, closely adjacent the inner surface of a refrigerator door. The ejection spout defines a nozzle that is angled downwardly and rearwardly to direct the discharge path of the spout into a container placed in the fill chamber. This assembly to be coupled to a resilient-walled vessel includes a tip defining an unobstructed bore positioned to be in direct communication with the vessel when coupled to the vessel. The tip includes a valve structured to allow drop-wise liquid dispensing and to prevent liquid back flow at zero as well as near zero pressure differentials across the valve. The assembly also includes at least one vent opening structured to allow air into and out of the vessel. It provides a cap having an antibacterial liner. The combination of the filtration element, antibacterial liner in the cap and the ability of the valve to prevent back flow. It enables the solution in the vessel to remain sterile without preservatives.

The liquid drainer is a float valve that opens to allow liquid to pass, but closes when the liquid level drops. It is a small vapor bypass to prevent vapor binding of the valve. The liquid drainer controls a different behavior of the pressure in the coil during defrosts in comparison to the pressure-regulating valve. The regulating valve allows the pressure in the coil to rise to its pressure setting, where it remains. With the drainer, the pressure in the coil will continue to rise until it nearly reaches the pressure of the incoming defrost gas. Equipping the coil with the bypass valve is particularly critical so that high coil pressure is not suddenly discharged into the suction line, when defrost terminates.

Liquid Epoxy Primer is designed for adhesive applications requiring quick gelling with amine curing agents. It comprises a liquid epoxy resin, a hydrophobic polyamine compound, a thixotropic agent, and a silane coupling agent. It is also designed for machine, spray, or hand brush applications to mechanically cleaned pipe surfaces.
