Abstract: A gas flow valve assembly. The assembly includes a cylindrical housing and a resiliently-biased valve supported substantially centrally within the housing. In the default or “off” condition, the resilient bias causes the valve to be seated on a valve seat shutting off axial flow of gas through the valve housing. When the patient breathes, negative pressure is applied to one side of the valve effective to sufficiently overcome the resilient bias imposed on the valve to move the valve off the valve seat axially (or otherwise open in another direction) within the housing, thereby allowing flow of gas through both the valve seat and the valve housing, and into the breathing circuit connected thereto. When the patient's breathing pauses and begins to exhale, the valve bias returns the valve to its default or off condition shutting off flow of gas through the valve.

Abstract: A portable fresh water supply apparatus for providing continuous fresh water to an animal when a caregiver is absent includes a reservoir capable of receiving and dispensing fresh water and a water supply line in fluid communication with the reservoir. A shut-off valve is located within the reservoir and is in fluid communication with the water supply line. A water drain line is in fluid communication with the reservoir, and an over-flow drain valve is located exterior of the reservoir as well as in fluid communication with the water drain line. In this manner, when a water level inside the reservoir reaches a threshold level, the shut-off valve is automatically toggled between open and closed positions and thereby selectively supplies fresh water from the water supply line to an interior of the reservoir. The overflow drain line diverts excess water away from the reservoir.

Abstract: Methods and systems for providing liquid feed to livestock deliver the liquid feed to a feeding station at a temperature below that of the mother's natural milk to encourage use of the liquid feed by the young as a supplement and not a replacement. A second reservoir expands the capacity of the system without increasing the size of the mixing reservoir. The second reservoir is equipped with selectively operable refrigeration and heating elements to facilitate cooling of the liquid feed or heating of a cleaning solution. A peroxide doser introduces small quantifies of peroxide to clean the liquid feed and prevent gorging. Orifices through which feed is discharged at feeding stations decrease in cross sectional area along the circulation line in the direction of flow to counteract variation in discharge flow rates caused by a pressure differential in the liquid feed along the line.

Abstract: A system intermittently feeding liquid to animal cages has a duct feeding liquid to liquid dispensers for the animals. Each dispenser includes: a lower portion with a liquid dispensing pipette for supplying liquid to the animals, an upper portion having a liquid flow rate adjuster in fluid flow relationship with liquid in the duct, and a buffer between the pipette and flow rate adjuster.
