  • Patent number: 11371902
    Abstract: A pressure transmitter includes a housing and a pressure sensor having an electrical characteristic that varies with applied pressure. The pressure sensor is configured to generate a sensor signal indicative of process fluid pressure. A transmitter isolation diaphragm is configured to couple to a process barrier seal to convey pressure to the pressure sensor. A flange is coupled to the transmitter isolation diaphragm. The flange includes at least one gas pathway extending inwardly from an outer diameter of the transmitter isolation diaphragm. Electronics are coupled to the pressure sensor to receive the sensor signal and to generate an output indicative of the pressure.
    Type: Grant

  • Patent number: 8832661
    Abstract: A method, apparatus and computer product for installing and testing an application on a highly utilized computer platform comprising: determining spare computing capacity of the computer platform over a utilization period; determining workload capacity required by the computer platform for installing the computer application and performing one or more diagnostic tests on the installed computer application; and scheduling deployment and performance of the one or more diagnostic tests to avoid periods where there is low computing capacity based on a predicted recurrence of the spare computing capacity over a similar future utilization period whereby the scheduling aims to provide sufficient system capacity for running an accumulated extra workload of the new application and the additional diagnostic tests required to verify the deployment of the one or more diagnostic tests.

  • Patent number: 5122393
    Abstract: A source assembly adapted to provide one or more metal organic compounds into an MBE reaction chamber wherein the source assembly comprises a mixer manifold which has one or more inlet connectors for providing the metal organic compounds. Each inlet connector includes a resistance valve for defining a flow rate of vapour of the metal organic compound under a pre-set pressure gradient and an on/off valve for selecting the operational status of the source. Preferably the mixer manifold acts as a collimator which avoids the need to fit a rotating substrate.

  • Patent number: 4447276
    Abstract: A method of growing crystalline semiconductors such as GaAs is disclosed. The method involves epitaxial deposition from the vapor phase and provides dopant material such as sulphur in the form of a molecular beam. The molecular beam is developed by effusion from a knudsen cell. The difficulties previously encountered using sulphur as such a cell are counteracted by use of an electrochemical cell as the sulphur source. The technique allows complicated doping profiles to be produced.
