Abstract: A method for upgrading a portion of a process control system from a legacy programmable logic controller (PLC) to a non-PLC process controller is disclosed. A mounting rack sized to fit into a space occupied by legacy hardware is assembled and populated with replacement hardware that includes an I/O card, an I/O terminal block, and a custom interface module. The custom interface module is coupled to the I/O card via the I/O terminal block and to a plurality of process control field devices via a legacy wiring mechanism coupled to legacy wiring of the process control system, without requiring modification or re-termination of the legacy wiring. The legacy wiring mechanism is disconnected from the legacy hardware, the rack containing the legacy hardware is removed and replaced with the mounting rack, and the legacy wiring mechanism is coupled to the custom interface module.

Abstract: Examples disclosed herein relate to conduits, devices, systems and methods, which may include a dispensing device including a valve configured to interact with an inlet stream, the inlet stream having a first pressure, the valve having an outlet area with an outlet stream, the outlet stream having a second pressure; and a solenoid configured to interact with the outlet stream.

Abstract: An attic vent has a base component, a dome-shaped cover, and a mounting mechanism for mounting the dome-shaped cover onto and over the base component. The base component has a mounting plate with a vent opening having a vertical wall surrounding the vent opening and extending upwardly from the mounting plate and to an upper rim. A diverter extension wall extends upwardly from the upper rim on a plane that is orthogonal to the mounting plate, and further an open grill extends upwardly from the upper rim at an inward angle from the diverter extension wall. The dome-shaped cover extends outwardly and downwardly to a bottom edge, while covering the open grill. The mounting mechanism further extends downwardly over the vertical wall and is spaced from the mounting plate.

Abstract: A liquid dispensing system comprises a container enclosing a chamber. A flexible bag in the chamber contains a first liquid. First and second conduits are contained in the chamber. The first conduit connects the chamber to an outlet port in the container where the second conduit connects the bag to the first conduit. A supply source introduces a pressurized second liquid into the chamber. The first conduit serves to direct an existing flow of the second liquid from the chamber to the outlet port, with the pressurized second liquid serving to collapse the bag and expel the first liquid contained therein via the second conduit to the first conduit for mixture with the exiting flow of the second liquid. The second conduit lacks flow restrictions, such as metering orifices or the like.

Abstract: Systems and methods for using alternate computer instruction sets are disclosed. In one embodiment, a method of program execution using an alternate instruction set may include (1) enabling a computer processor to use an alternate instruction set; (2) a first computer program in memory issuing a first instruction for execution by the computer processor; (3) the computer processor determining that the first instruction issued by the first computer program is in the alternate instruction set; (4) the computer processor translating the first instruction issued by the first computer program; and (5) the computer processor executing the translated instruction.

Abstract: Examples disclosed herein relate to conduits, devices, systems and methods, which may include a hollow element including an inner surface and an outer surface which allows for a passage of one or more of one or more fluid elements and one or more gaseous elements, a constraining element with one or more openings and one or more non-open elements, one or more blocking elements configured to stop the passage of the at least one of the one or more fluid elements and the one or more gaseous elements when the one or more blocking elements are in a first position relative to the one or more openings, and a movement device configured to move the one or more blocking elements to a second position relative to the one or more openings which allows for the passage of the one or more fluid elements and the one gaseous elements through the one or more openings in the constraining element.

Abstract: A technique provides a phone call from a caller device operated by a human caller to an answerer device operated by a human answerer. The technique involves receiving a call request from the caller device. The call request includes a call button identifier which uniquely identifies a browser call button which is rendered on the caller device to the caller. The technique further involves identifying a source phone number based on the call button identifier. The technique further involves placing a call communication to the answerer device operated by the human answerer. The call communication indicates the source phone number as a source of the call communication. Accordingly, if the answerer device already has the context of associated with the source phone number already saved (e.g., in a contact list), the answerer device is able to automatically display that context in response to the call.

Abstract: A system for the on demand delivery of a liquid mixture to an on/off dispenser comprises a mixing chamber having first and second inlets and an outlet connected to the dispenser. A first constant flow valve has a first outlet connected to the first inlet via a first supply line. The first constant flow valve is adapted to deliver a first liquid to the mixing chamber at a first substantially constant pressure. A second constant flow valve has a second outlet connected to the second inlet via a second supply line. The size of the second inlet is at least as large as the size of the second outlet. The second constant flow valve is adapted to deliver a second liquid to the mixing chamber at a second pressure greater than the first pressure, with the second pressure being determined primarily by the flow resistance of the second supply line. At least one of the first and second liquids, or a third liquid delivered to the mixing chamber via a third supply line, may be atomized.
