  • Publication number: 20240100377
    Abstract: Automatic fluid control assemblies and methods for fire protection include an arrangement of electrically operated control points, a valve body and a controller to operate the fluid control assembly. The automatic fluid control assembly has an inlet, an outlet and a valve body to control flow between the inlet and the outlet. An electric latch includes a first electrically operated control point and a second electrically operated control point in fluid communication with a control line to control the flow of fluid from the inlet to the valve body and outlet. The methods of fluid control include controlling a plurality of electrically operated control points to perform any one of: a leak test, a trip test, a flow test, a water delivery test, and a validation test of a non-trip condition and a trip condition.

  • Patent number: 11846221
    Abstract: An evaporative emission control canister system comprises an initial adsorbent volume having an effective incremental adsorption capacity at 25° C. of greater than 35 grams n-butane/L between vapor concentration of 5 vol % and 50 vol % n-butane, and at least one subsequent adsorbent volume having an effective incremental adsorption capacity at 25° C. of less than 35 grams n-butane/L between vapor concentration of 5 vol % and 50 vol % n-butane, an effective butane working capacity (BWC) of less than 3 g/dL, and a g-total BWC of between 2 grams and 6 grams. The evaporative emission control canister system has a two-day diurnal breathing loss (DBL) emissions of no more than 20 mg at no more than 210 liters of purge applied after the 40 g/hr butane loading step.
