Abstract: A valve for a water line for preventing or reducing air from being read by a water meter or other device as water. The preferred form of the valve is in line adjustable, i.e., without removing the valve from the water line and/or without shutting-off the flow of water through the water line to vary the force necessary to open the valve to allow a fluid to flow therethrough. Preferably, the valve includes a simple user manipulated tool to vary the force necessary to open the valve from a maximum force to a minimum force without detaching the user manipulated tool from the valve. The force adjusting features disposed in the valve housing are designed to maximize fluid flow through the valve housing while still allowing inline adjustment of the valve. Preferably, the valve includes an anti-tampering member that prevents an unauthorized user from altering the force necessary to open the valve.

Abstract: A powder feed nozzle for laser welding applications including a multiple outlet nozzle tip for focusing a discharged powder stream. The multiple outlet nozzle tip disperses multiple outlet streams and includes a powder discharge outlet and at least one focus gas discharge outlet, radially spaced from the powder discharge outlet, for dispersing a powder stream and a gas stream. Powder flows from a powder source through a powder channel to discharge a powder stream. Focus gas flows through a focus gas channel angled relative to the powder channel to discharge a focus gas stream.
