  • Injection system having skirt walls forming an annular seal walls
    Patent number: 8985998
    Abstract: An injection system, in an apparatus for injection-molding plastics, comprises a manifold plate (2) having an injection nozzle (3) closed by a valve stem (7) commanded by a dual-effect pneumatic linear actuator (8, 9) wherein a piston cylinder (8) is compressed between a back plate (10) and a hot runner manifold (5). The piston cylinder bounds an annular gap into which the compressed air that drives the actuator can flow.
    Type: Grant

  • Gas sensor chamber and odor detection method
    Patent number: 7051573
    Abstract: The invention relates to a chamber (2) for gas sensors (9) to be used in a device (1) for detecting aromas or odors. The chamber (2) comprises three portions (5, 6, 7) in which there is a uniform, turbulence-free flow (F) of gas or vapors to be analyzed, and at least one gas sensor (9) positioned in the central portion in such a way as to be immersed in and to laterally and tangentially interact with the flow (F). The chamber (2) also comprises a heating and temperature regulating device (16, 17). The invention also relates to an odor detection method which comprises a step in which a uniform, turbulence-free flow (F) of gas or vapor interacts with a gas sensor (9) laterally and tangentially.
