  • Patent number: 8093917
    Abstract: A sampling apparatus for sampling a fluid from a fluid source includes a first fluid passage device, a second fluid passage device and a fluid by-pass. The first fluid passage device is disposed downstream of and in fluid communication with the fluid source. The second fluid passage device is disposed downstream of and is in fluid communication with the first fluid passage device. The fluid by-pass is disposed downstream of the fluid source and upstream of the second fluid passage device. The fluid by-pass being in fluid communication with and disposed between the fluid source and the second fluid passage device is operative to cause a first portion of the fluid to flow through the first fluid passage device and to cause a second portion of the fluid to by-pass the first fluid passage device and to flow to the second fluid passage device.

  • Patent number: 8049522
    Abstract: An ice thickness probe includes a longitudinally-extending probe rod, an insulator casing and a sleeve. The probe rod is fabricated from an electrically-conductive material. The insulator casing is fabricated from an electrically-insulative material and is wrapped around, is in contact with and extends along the probe rod. The sleeve is fabricated from a stiff yet resilient material and is wrapped around, is in contact with and extends along the insulator casing. The insulator casing and the sleeve are concentrically disposed about the probe rod as viewed in cross-section. An ice thickness probe assembly includes a frame structure, a reference bar and at least one ice thickness probe. An ice thickness monitoring apparatus is used in a thermal storage coil having a tank containing water and a tube disposed in the water so that, when the thermal ice storage coil is energized, ice is produced and accumulates on the tube.

  • Publication number: 20110100593
    Abstract: A hybrid heat exchange apparatus for indirectly transferring heat between a process fluid and ambient air includes an evaporative heat transfer cell operative in a wet mode or a dry mode, a dry heat transfer cell and a fan. The air may bypass the dry heat transfer cell to flow through a first air passage or may flow through a second air passage through the dry heat transfer cell and in either event, then through the evaporative heat transfer cell. The air may partially flow through and partially bypass the dry heat transfer cell, and then through the evaporative heat transfer cell. The evaporative heat transfer cell optionally may include a direct contact evaporative heat exchanger. Manually or automatically controlling air flow based on ambient conditions provides efficient and economical control of the hybrid heat exchange apparatus, while avoiding problems in freezing conditions.

  • Publication number: 20090188650
    Abstract: A liquid distribution system for an evaporative heat rejection system that includes a heat transfer surface is disclosed. The liquid distribution system includes a plurality of liquid conduits adapted to transport liquid for distribution over the heat transfer surface, and each liquid conduit having at least one orifice. At least a first orifice in a first conduit and a second orifice in a second conduit are positioned such that when the liquid is transported under a predetermined pressure thought the conduits, the liquid is emitted from the first and second orifices in first and second streams, respectively, that collide at a collision site, thus causing liquid to be scattered from the collision site and distributed over the heat transfer surface.

  • Patent number: 7501596
    Abstract: A dimension sensor is used in conjunction with a tube and includes a body member and at least one detector element. The body member has an inner surface defining an opening sized to receive the tube. The at least one detector element is connected to the body member and has a detector portion extending into the opening. When the tube is received in the opening, the detector portion is initially disposed apart from the tube. A method using the dimension sensor stops expansion of the tube expanding from a pre-expanded state to a desired expanded state. A pumping device is actuated to pressurize a fluid by an amount sufficient to cause the tube to expand from the pre-expanded state to the desired expanded state. When the tube expands to the desired expanded state, the pumping device deactivates thereby stopping expansion of the tube at the desired expanded state.
