  • Patent number: 9610466
    Abstract: A fire protection system includes a dry pipe system and a controlled discharge gas vent. The dry pipe system and controlled discharge gas vent operate using a breathing cycle to displace oxygen and/or water vapor from within the piping network of the dry pipe system. The controlled gas discharge vent allows displacement of pressurized air with nitrogen, for example, using manual or automated processes that can employ one or more sensors. Corrosion resulting from oxygen, water, and/or microbial growth is reduced or nearly eliminated.

  • Patent number: 8322417
    Abstract: An actuator is disclosed which operates on the principle of the variable magnetic properties of materials with respect to temperature. As temperature is raised past Curie temperature, magnetic permeability of certain materials drops significantly to a value close to free space permeability. However, depending on the material selection, magnetic permeability may be significantly higher below Curie temperature. This principle is used to cause magnetic attractive force to move an actuator at one temperature, while permitting a return spring force to move the actuator at another temperature by changing the pathway traversed by most magnetic lines of flux from a magnetic source. The actuator may be employed to provide a temperature activated electrical switch or fluid valve. The temperature activated valves are suited to use in high temperature environments, such as SAGD wells.

  • Patent number: 8141574
    Abstract: The housing is attachable to a high pressure fluid containing structure. A piston is provided within the housing, with the piston having a closed position and an open position. The closed position blocks an outlet vent of the relief device, with the open position allowing high pressure fluid to escape through the vent. The piston is biased toward the open position by the high pressure fluid, but is held in the closed position by a slide. The slide has a first position and a second position, with the first position holding the piston in the closed position. A spring biases the slide toward a second position, with a eutectic mass resisting movement of the slide to the second position. The eutectic mass is selected to have a melting point matching a maximum design temperature for the high pressure fluid containing structure. Should the eutectic mass melt, the high pressure fluid escapes.

  • Patent number: 8062108
    Abstract: A self-closing vent intended for use in attics, crawl spaces, joist cavities, exterior walls, interior walls, or other structural element which allows for the free flow of air from outside a building to interior spaces during normal use. The vent includes a damper blade pivotally connected to, and disposed within, the vent housing, which is held in an open position by a temperature sensitive fusible link. Two, and preferably three, permanent magnets provide the force for driving the damper blade into a closed and locked position. A first magnet disposed in a side of the vent housing and a second magnet disposed on the damper blade are disposed with opposing (repelling) polarities when the damper blade is held in the open position. A third magnet disposed proximate the back of the vent housing is oriented so as to attract the magnet disposed on the damper blade.
