Expanding gases are released into a chamber defined in part by a housing and in part by the caulk cartridge, the plug or piston within the cartridge forming a boundary of the chamber.

Abstract: The present invention provides improved method and apparatus for the transfer and delivery of very high purity chemicals for use in semiconductor production and similar processes. By employing a series of vessels arranged in parallel, a vacuum system to draw chemical from one or more bulk sources into the vessels, and a pressure system to deliver chemical under pressure from the vessels, chemicals can be easily delivered from any bulk source to one or more end-users. The use of a vacuum system to draw chemicals through sealed conduits eliminates the need for pumps which are a source of both maintenance problems and contamination in the system. Multiple vessels provide for a variety of flow options, which include continuous and uniform chemical delivery to the end-users, recirculation and regular filtration during periods of low use, and built-in redundancy to avoid system shut down if there is a component failure. Computer controlled process systems provides system flexibility and full automation.

Abstract: Two-part reactive polymeric coatings are prepared and applied from an integral dispensing system. The reactive components are held in two separate containers held together by a coupling. Each container is sealed by a pierceable membrane. A piercing tube is disposed within the coupling. In use, the containers are twisted together to cause the tube within the coupling to pierce each of the membranes. Breakaway tabs protect against inadvertent displacement of the containers and provides a clear indication of whether the tube has pierced the membranes. Differential pressure between the containers causes the components to mix and begin to react; a net positive pressure with respect to the ambient atmosphere permits the mixed components to be applied as a spray. An externally mounted spray feed tube provides great flexibility in application of the paint being sprayed.
