Patent number: 11947884Abstract: An industrial CAD system is supplemented with features that allow a developer to easily convert a mechanical CAD model of an automation system to a dynamic digital twin capable of simulation within a simulation platform, including simulation of fluid dynamics throughout the system. The features allow the user to label selected elements of a mechanical CAD drawing with “aspects” within the CAD environment, and to add fluid models representing fluids that travel through or are processed by the system. Based on these aspect labels and fluid models, the CAD platform transforms the mechanical CAD model into a dynamic digital twin that can be exported to a simulation and testing platform to facilitate simulation of both machine operation and fluid dynamics.Type: GrantFiled: December 22, 2022Date of Patent: April 2, 2024Assignee: Rockwell Automation Technologies, Inc.Inventors: Ian McGregor, David Dawkins, Adam Davidson

Patent number: 11597691Abstract: A process for synthesising methanol is described comprising the steps of (i) passing a feed gas comprising a make-up gas containing hydrogen and carbon dioxide to a methanol synthesis loop, (ii) recovering a product gas mixture containing methanol from the methanol synthesis loop, (iii) cooling the product gas mixture to below the dew point to condense crude methanol, (iv) separating the crude methanol from an unreacted gas mixture, (v) passing a portion of the unreacted gas mixture to the methanol synthesis loop and (vi) recovering a portion of the unreacted gas mixture as a purge gas stream, characterised by contacting the crude methanol and a portion of the purge gas in a stripping unit to strip dissolved gases from the crude methanol thereby forming a stripped crude methanol and an enriched gas mixture, and feeding at least a portion of the enriched gas mixture to the methanol synthesis loop.Type: GrantFiled: April 16, 2019Date of Patent: March 7, 2023Assignee: Johnson Matthey Davy Technologies LimitedInventors: Simon Robert Early, David McGregor Turnbull

Patent number: 11305040Abstract: Dialysis systems and methods are described which can include a number of features. The dialysis systems described can be to provide dialysis therapy to a patient in the comfort of their own home. The dialysis system can be configured to prepare purified water from a tap water source in real-time that is used for creating a dialysate solution. The dialysis systems described also include features that make it easy for a patient to self-administer therapy. For example, the dialysis systems include disposable cartridge and patient tubing sets that are easily installed on the dialysis system and automatically align the tubing set, sensors, venous drip chamber, and other features with the corresponding components on the dialysis system. Methods of use are also provided, including automated priming sequences, blood return sequences, and dynamic balancing methods for controlling a rate of fluid transfer during different types of dialysis, including hemodialysis, ultrafiltration, and hemodiafiltration.Type: GrantFiled: August 7, 2015Date of Patent: April 19, 2022Assignee: Outset Medical, Inc.Inventors: Michael Edward Hogard, Gopi Lingam, Dean Hu, Balaji M.

Patent number: 8074874Abstract: A system for the authentication by a card-issuing financial institution of identifying information of a card-holding user of a public data network. The system includes a secure data entry device connected to the public data network and a gateway device connected to the public data network and to a private data network used for transmitting messages between financial institutions. The secure data entry device enables the user to enter identifying information of a card issued by the card-issuing financial institution, and transmits the identifying information in a secure manner over the public data network to the gateway device. The gateway device transmits the identifying information to the card-issuing financial institution and receives an approval response from the card-issuing financial institution over the private data network. The approval response provides authentication of the identifying information by the card-issuing financial institution.Type: GrantFiled: November 26, 2004Date of Patent: December 13, 2011Assignee: Point of Paypty LtdInventors: Hector Daniel Elbaum, Andrew Jamieson, David McGregor
