  • Patent number: 10860195
    Abstract: Configuring graphical display views to be presented, at a user interface of an operating environment of a process plant, using multiple graphical display themes includes configuring a display theme object to indicate a plurality of themes via which the display view is able to be presented at the user interface. The display theme object includes a parameter whose value is changeable, within the operating environment, to indicate a desired theme that is to be utilized, and the display theme object is downloaded from the configuration environment into the operating environment. Thus, during runtime, changing the theme via which the graphical display view is presented is achieved without any additional downloads from or communications with the configuration environment. User controls may be provided to an operator to select different themes, and/or to override various visual aspects of themes to achieve optimum visibility. Themes may be automatically changed based on sensed conditions.

  • Patent number: 10788972
    Abstract: Techniques for presenting historized process parameter values in a process plant include presenting, via a user interface of an operator application, indications of process control elements in a first display region within a layout of a display view. Each of the process control elements is associated with one or more process parameters. The operator application also presents a trend display view in a second display region within the layout of the display view. The trend display view includes sets of historized process parameter values for process parameters presented in the first display region. For example, the trend display view in the second display region is linked to the display view in the first display region. In this manner, the trend display view presents charts or other graphical depictions of historized process parameter values for process parameters included in the first display region.

  • Publication number: 20200103881
    Abstract: Drones (e.g., unmanned aerial vehicles, or “UAVs”) equipped with cameras and sensors may be configured to travel throughout the field environment of a process plant to monitor process plant conditions. Onboard computing devices associated with the drones control the movement of the drones through the field environment of the process plant. The onboard computing devices interface with the cameras and other sensors and communicate with user interface devices, controllers, servers and/or databases via a network. The onboard computing devices may receive drone commands from user interface devices and/or servers, or may access drone commands stored in one or more databases. The onboard computing devices may transmit data captured by the cameras and/or other sensors to UI devices, controllers, servers, etc. Accordingly, the user interface devices may display data (including live video feeds) captured by the drone cameras and/or drone sensors to an operator in a human machine interface application.

  • Publication number: 20200018841
    Abstract: A method of operating a vertical incidence sounder. The sounder transmits a random modulated sounder signal, and receives a return signal, comprising a directwave component and a reflected component. A first cross-ambiguity process between the transmitted signal and the return signal is used to time and frequency align the return signal with the transmitted signal. The direct wave signal is removed, thereby producing a processed return signal. A second cross-ambiguity process between the transmitted signal and the processed return signal is performed to determine a time offset, which is used to estimate an ionospheric height.

  • Patent number: 5886289
    Abstract: A long range artillery shell (1) comprising rocket propellant material (10), a rocket motor nozzle (14) and base bleed propellant material (12). Ignition of the rocket propellant material (10) is delayed until the base bleed propellant material (12) has substantially finished burning. The base bleed propellant material (12) may be housed in the same chamber and behind the rocket propellant material (10) in order to provide support to the rocket propellant material (10) during launch. The two propellant materials (10, 12) may be separated by a thermal ignition barrier (18) to prevent premature rocket ignition.

  • Patent number: 4554748
    Abstract: A multi-segment seal ring for rotary equipment of the type involving a relatively large-diameter rotary cylinder supported with its axis horizontal by one or more fixed housings, seals being employed between the cylinder and at least one of the housings. One problem in equipment of this type is the practical impossibility of manufacturing and maintaining the cylinder as a perfect cylinder and special sealing structures are typically employed to accommodate out-of-round conditions of the cylinder, an example of which forms the subject matter of copending U.S. application, Ser. No. 618,984, filed June 8, 1984, now U.S. Pat. No. 4,502,702. The present invention provides improvements in the configuration and sealing of the gaps that occur at the overlapping, radial interfaces between neighboring segments, particularly to the end of increasing the efficiency of the equipment by eliminating or at least minimizing packing of treated material in the gaps.

  • Patent number: 4502702
    Abstract: A seal assembly for effecting a seal between a stationary housing and a rotatable cylinder includes a plurality of arcuate segments radially disposed about the outer circumference of the cylinder. Each segment has an axial sealing surface defining a radius approximately equal to that of the rotatable cylinder and additionally has an end section for overlapping adjacent segments thus creating a gap and radial interface between the adjacent circumferentially disposed segments. The sealing assembly additionally comprises means for sealing the gaps formed by the adjacent overlapping segments, apparatus for tensioning the segments radially about the outside circumference of the cylinder and studs for removably attaching each segment to the housing while concurrently permitting radial displacement of each segment independently from its adjacent segments.
