  • Publication number: 20190247691
    Abstract: A corrosion monitoring system of a fire protection system includes at least one first antenna and a processing circuit. The at least one first antenna receives a radio frequency (RF) signal through an internal volume of at least one pipe of the fire protection system. The processing circuit includes one or more processors and memory including computer-readable instructions that when executed by the one or more processors, cause the one or more processors to determine a signature of the RF signal, compare the signature to an expected signature, and determine, based on the comparison, that corrosion in the at least one pipe has occurred.

  • Patent number: 9243848
    Abstract: A water heating system includes a burner assembly for providing a source of thermal energy to a heat exchanger. A water inlet conduit is coupled to the heat exchanger assembly for supplying fresh water to be heated, and a water exit conduit is coupled to the heat exchanger assembly for delivering the heated water to a point of use. A bypass conduit connects the water exit conduit to the water inlet conduit, and a pump disposed in the bypass conduit circulates at least a portion of the heated water from the water exit conduit to the water inlet conduit. A feed-forward sensor positioned in the water inlet conduit between the heat exchanger assembly and the bypass conduit monitors a parameter of the water entering the heat exchanger assembly, and a processor controls the operation of the of the burner assembly in response to the feed-forward sensor.

  • Publication number: 20160009853
    Abstract: The present invention is directed at water-reducible curing agents for epoxy resins, obtainable by reacting at least one diprimary amine, at least one mono-primary amine and at least one polyepoxy compound, wherein the molar ratio of the primary amino groups to the epoxy groups in the reaction is in the range of about 1.7:1 to 1:1, the ratio of the primary amines in the diprimary amine to secondary amines optionally present in the diprimary amine is more than 1:1, and the molecular weight (Mw) of the diprimary amine is 500 Daltons or less. These water-reducible curing agents show excellent utility in combination with epoxy resins for self-levelling applications and provide excellent finished properties such as high compressive strength, low shrinkage, high impact resistance and high wear resistance in comparison to the commercially available products.
