Abstract: Systems and methods for configuring an analog process alarm in digital control devices are provided. In one example embodiment, a system may include a logic editor configured to create templates, including one or more alias names for corresponding one or more analog alarm sub-variables associated with an analog process variable, within the digital control system; a human-machine interface configured to provide to a user an analog alarm virtual block diagram visualizing processing logic associated with the analog process variable within the digital control system and to receive from the user a request to select a template from the created templates; and a template generator configured to automatically generate, based on the selection of the template, the alias names for the corresponding analog alarm sub-variables of the analog process alarm. The alias names may be defined directly on the analog process variable.

Abstract: Certain embodiments herein relate to automated display of permissive logic in control systems associated with a power generation unit. A control device may be configured to provide automated updates of system data, such as signals received from power generation equipment, to an HMI or SCADA display, as non-limiting examples. A logic builder block may receive permissive logic configurations, including one or more combinational logic blocks. A logic builder block may be associated with power generation equipment to facilitate the identification of related system data and the subsequent association of the system data to corresponding input pins for the combinational logic blocks. The permissive logic configurations may be compiled into object code and downloaded to the control device, where it may be executed to perform the above described functions, among other functions.

Abstract: A dynamic alarm system for operating a power plant is disclosed. The dynamic alarm system includes a sensor configured to generate a signal related to a measurement of an operation of the power plant. An interface displays a generated alarm to an operator and receives a dynamic rating value from the operator related to the generated alarm. A processor generates the alarm using the generated signal, compiles the rating value and alters an operation of the power plant from the compiled rating value.

Abstract: A dual use fluid filtration tool to separate both solids and gas from a fluid. The fluid filtration tool is suspended from and connected to downhole equipment, such as a downhole submersible pump having a motor, which rotates a shaft. The tool includes a housing having a cylindrical wall with a plurality of perforations therethrough and an interior chamber therein. A removable cylindrical filter surrounds the interior chamber of the housing in order to filter solid particles. At least one centralizer bearing within the interior chamber of the housing centralizes the shaft which passes therethrough. The fluid in the interior chamber is radially induced in order to separate gas from fluid. The gas separated from the fluid is directed out of the chamber while the fluid remaining in the interior chamber is directed to the intake of the downhole pump.

Abstract: An isolation container designed for use with a downhole electric pump assembly commonly used in oil and gas drilling and production operations is disclosed. The isolation container has an annular housing with an axial inlet and outlet bore. A downhole electric pump assembly is centrally located within the pressure isolation container. The downhole electric pump assembly includes an electric pump positioned above and coupled to a motor seal section which is positioned above and coupled to a centrifugal pump, thereby providing a means to power the centrifugal pump. A blind coupling is positioned above the electric motor with a tubular member connected thereto and extending through the inlet of the isolation container. The tubular member connects to a tubing string supplying fluid from the surface. The blind coupling has a plurality of radially disposed ports to allow pressurized fluid from the surface to flow into the annulus between the downhole electric pump and the isolation container.

Abstract: A compact shuttling printer mechanism suitable for use with dot forming print elements is disclosed. A single part plastic molding forms the frame and shuttling suspension for the print head or heads. The design utilizes a compound cantilevered spring principle. A linear reciprocable drive element acting as close as possible through the center of percussion of the print head and suspension assembly reciprocates the print head back and forth along a desired print line adjacent to a platen. Means for incrementing paper at the end of each reciprocation or stroke are provided. The design is adapted to provide print line visibility so that printed characters may be seen as they are formed. The reciprocation drive operates without orthogonal forces. It provides a purely linear drive force so that the machine is free of unwanted vibrations in other planes or axes. The unitary molded plastic compound cantilever spring and frame assembly greatly reduces the size, cost and complexity of the printing mechanism.
