  • Wireless field maintenance adapter
    Patent number: 8224256
    Abstract: A wireless field maintenance adapter includes a power source, a controller, a low-power radio-frequency communication module, and a wireless process communication protocol module. The controller is coupled to the power source. The low-power radio-frequency communication module is also coupled to the controller. The wireless process communication protocol module is coupled to the controller. The controller is configured to communicate through the wireless process communication protocol module based on information received from the low-power radio-frequency communication module.

  • Multi-protocol field device interface with automatic bus detection
    Patent number: 8112565
    Abstract: A multi-protocol interface for coupling a field device to a general purpose computer is disclosed. The interface includes measurement circuitry to perform a plurality of measurements on a connected process communication loop to determine a process communication loop type. Then, if the interface includes a protocol interface module that matches the detected loop type, the protocol interface module can be engaged. A method for coupling a field device to a general purpose computer is also provided. In one aspect, power from the general purpose computer is used to power the process communication loop, if the interface determines that the loop is not powered.

  • Integrated alert generation in a process plant
    Patent number: 7557702
    Abstract: Operational status information associated with a process entity in a process plant is received. The operational status information is mapped into one of a plurality of status conditions. Then, an alert message associated with the process entity is generated, where the alert message is indicative of the one status condition of the plurality of status conditions.

  • Pressure-sensitive adhesives based on emulsion polymers
    Patent number: 5492950
    Abstract: There is provided a mixture of acrylic emulsion polymers based on 70 to 95 parts by weight of a first polymer containing from about 95 to 97.5% by weight of an alkyl ester of acrylic acid and from about 2.5 to 5% by weight of a mixture of carboxylic acids tackified by a second acrylic emulsion polymer containing 10 to 20% by weight of carboxylic acid or hydroxyethyl methacrylate.

  • Photochromic 3-pyrryl fulgides and fulgimides
    Patent number: 4737449
    Abstract: A series of novel 3-pyrryl fulgides and fulgimides are disclosed which are photochromic. The photochromic compounds are coloured by subjecting them to irradiation in the near ultraviolet and will revert to the colourless form on exposure to visible light, especially light having a wavelength in 600 to 650 nm band.
