Patent number: 11859903Abstract: A method of constructing a coil wound heat exchange module and transporting and installing the coil wound heat exchange module at a plant site, such as an natural gas liquefaction plant. A module frame is constructed and attached to a heat exchanger shell prior to telescoping of a coil wound mandrel into the shell. The module frame includes a lug and two saddles that remain attached to the shell throughout the process and when the heat exchanger is operated. The lug and saddles are constructed and located to stabilize the shell during construction, telescoping and transport (when in a horizontal orientation), and when the shell is installed at the plant site (in a vertical orientation). The lugs and saddles are adapted to allow for thermal expansion and contraction of the shell when it is transitioned from ambient to operating temperature and vice versa.Type: GrantFiled: June 9, 2022Date of Patent: January 2, 2024Assignee: Air Products and Chemicals, Inc.Inventors: Joseph E. Voda, Adam R. Garcia, Kevin E. Tiemann, Christopher J. Ranella, Paul I. Debrah, John A. Dally

Publication number: 20060153068Abstract: Disclosed are systems and methods which provide high availability with respect to equipment deployed in a distributed system architecture. The distributed system architecture may comprise one or more equipment clusters of a plurality of processor-based systems cooperating to host one or more application servers. Redundancy is provided with respect to equipment of the equipment clusters to provide high availability with respect to equipment used in providing services of the application servers as well as to provide continuity of applications provided by the application servers. Various equipment elements of an equipment cluster may be provided different levels and/or types of redundancy. Other equipment elements of an equipment cluster may be provided different levels and/or types of redundancy.Type: ApplicationFiled: December 17, 2004Publication date: July 13, 2006Applicant: Ubiquity Software CorporationInventors: John Dally, Michael Doyle, Steve Hayward, Gethin Liddell, James Steadman
