  • Manifold system of removable components for distribution of fluids
    Patent number: 6394138
    Abstract: A manifold system for enabling a distribution of fluids includes a plurality of individual manifold blocks that can be joined together to form a gas stick. Each manifold block will have a fluid passage way with an entrance port and exit port accessing a common surface. An active component can be mounted to one manifold block, while extending across a port of an adjacent manifold block. An alignment system can be provided to ensure that the entrance and exit ports are positioned in a plane containing the common surface to facilitate sealing.
