  • Publication number: 20220082206
    Abstract: A display device support arm comprises: a securing component; a first support arm element pivotally attached to the securing component and coupling to an attachment means for receiving a coupling mechanism, incorporating a load indicator, at the lower end of a second support arm element. At the other end thereof is an attachment head and a display mounting head rotatably secured thereto. The mounting head includes a toothed arcuate surface to which there is pivotally mounted a trigger adapted to move one or more locking blocks out of biased engagement with the arcuate surface. Constant friction joints, a modified securing foot with tool holder, a tilt mechanism; a display rotation lock operably coupled to a display mounting interface; interchangeable rail assemblies; display mounting brackets for attachment to the rail assemblies; and methods of installing a support arm and setting a tilt mechanism are also defined.

  • Patent number: 8969423
    Abstract: In a process for the production of substitute natural gas, a feed gas is provided to a first and/or second and/or subsequent bulk methanator. The feed gas is subjected to methanation in the presence of a suitable catalyst. An at least partially reacted stream from the first bulk methanator is removed and supplied to the second and/or subsequent bulk methanator where it is subjected to further methanation. A product stream from the final bulk methanator is passed to a trim methanator train where it is subjected to further methanation. A recycle stream is removed downstream of the first, second or subsequent bulk methanator, and, in any order, passed through a compressor, subjected to cooling and then supplied to a trim and/or recycle methanator for further methanation before being recycled to the first and/or second and/or subsequent methanator.

  • Publication number: 20100287530
    Abstract: Techniques for requirements definition using interactive prototyping are described, including receiving an input from a client, wherein the client is installed on a first computer in data communication with an application simulation server implemented on a second computer, the input being manipulated to graphically identify a requirement for an application being generated using the first computer and the second computer, evaluating the input to identify executable program code associated with the requirement, transforming the input into the executable program code, wherein the application is designed by providing input at the first computer and simulated using the executable program code on the second computer, and generating an interactive simulation of the application by running the executable program code in a simulation environment on the second computer and displaying the application on the first computer, including one or more interfaces associated with the application.
