Abstract: This invention provides a system for eliminating gas bubbles from a liquid. The liquid enters a chamber through an inlet port. The chamber has two outlet ports, the first bounded by a hydrophilic filter which passes liquid but not gas, and the second bounded by a hydrophobic filter which passes gas but not liquid. Entrapped gas bubbles entering the chamber pass through the hydrophobic filter to the atmosphere. The degassed liquid passes through the hydrophilic filter into tubing leading to the desired receptacle. This apparatus and method are particularly suitable for intravenous infusions and other medical applications in which the degassed liquid passes directly into the blood vessels of a patient.

Abstract: In one exemplar embodiment, method and apparatus are provided for the airborne dispensing of loose, dry insect eggs from a container by gravity flow through a metering device to control the loose egg flow to a spreader for spreading the loose eggs in a desired broadcast pattern entrained in a flow of air. A slight vacuum is applied to the container dispenser device stimulating and enhancing the steady flow of the loose eggs from the container dispenser to the spreader device.
