  • Patent number: 7944393
    Abstract: A method for recording a position of at least one component in a location system of a control system of an industrial facility for an industrial process. A model of the facility is created, including position coordinates for major parts of the facility. The model is stored in a location system storage. A component is identified. A mobile information processing device is placed adjacent the component and position coordinates are detected for the mobile information processing device. Identification information of the component and position coordinates of the mobile information processing device are stored in the location system storage.
    Type: Grant

  • Patent number: 7664815
    Abstract: A method to provide technical information from a marine vessel to a remote location by means of a computer connected and logged in to a communication means of the marine vessel. The technical information concerns an equipment or system associated with, or installed on, the marine vessel. A communication session on the logged in computer is initiated. An address is selected from an address list of one or more technical specialists associated with the equipment. A message is sent to a remote address. A communication session on a remote computer system is initiated at the remote address with the logged in computer.

  • Patent number: 4098332
    Abstract: A plurality of mutually parallel finned tubes forming a heat exchanger are positioned so closely together that the peripheries of mutually oppositely extending segments of the tube's respective fins are not substantially interspaced. To support the finned tubes, one or more groups of those segments are shortened to form transverse passages through which tube support members are passed transversely with respect to the tubes.

  • Patent number: 4044605
    Abstract: The apparatus comprises a test tube having substantially the same composition as the heat-exchanger tube suspected as fouling internally. A pressure chamber encloses this test tube and forms a space around the test tube and isolated from external influences. This pressure chamber has means for filling the space around the test tube with a vapor that condenses to liquid on the outside of the test tube, the pressure in the pressure chamber being dependent on whether or not or the degree the vapor condenses to liquid on the test tube. Means are provided for measuring the fluid pressure on the inside of the pressure chamber, this means providing a measure of the heat exchange between the vapor and any medium flowing inside of the test tube.

  • Patent number: 3973624
    Abstract: Condenser for a gaseous media such as steam, comprising a plurality of longitudinal tubes, generally several thousands, through which a coolant passes. Steam is passed around these tubes, and the tubes are braced at selected locations in longitudinal direction by means of brace plates or the like, and the steam is passed from the periphery of the heat exchanger and toward the interior thereof during condensaton. The condenser comprises a casing or shell and one or more nests of tubes and means for circulating steam around the entire or greater part of the periphery, and within each tube nest, an air-cooler device is placed centrally or substantially centrally, which air-cooler extends along the entire length of the tube nest. The brace plates are provided with flow channels effective to distribute the gaseous media about the condenser in response to fluctuation in condensing capacity along the tube nests.
