  • Means and methods for predicting hold time in enclosures equipped with a total flooding fire extinguishing system
    Patent number: 5128881
    Abstract: Test apparatus and method for determining whether an enclosure containing articles of value susceptible to damage by fire and also by water is able to pass a hold time requirement in the performance specifications of a fire extinguishing system installed in the enclosure. The fire extinguishing system acts by injecting and distributing a volatile extinguishing agent in an initially generally uniform manner throughout the enclosure, and requires for effective action that a specified minimum concentration of the agent be maintained in specified regions of the enclosure for a specified minimum hold time.

  • Orifice metering fan device
    Patent number: 4631876
    Abstract: Disclosed is a device for generating and measuring the flow of a gas, the device being particularly adapted for measuring the magnitude of air infiltration in a building and for locating sources of air infiltration. The device of the invention comprises a propeller-type fan for generating gas flow mounted in a gas flow guide, a drive for rotating the fan, an orifice plate located upstream from the fan, a damper or drive controller for varying the gas flow rate through the orifice, and one or more flow-directing vanes between the orifice plate and the fan, the plane of the orifice plate being approximately parallel to the plane of rotation of the fan, and the orifice and fan being generally concentric and spaced less than one fan diameter apart.
