Patent number: 11953026Abstract: A submersible pump comprises a rotational assembly and a rotational assembly housing. The rotational assembly has a plurality of in-line flow inducing sections. A centerline longitudinal axis of each of the flow inducing sections extends colinearly with a rotational axis of the rotational assembly. A downstream end portion of a flow pressurizing section is engaged with an upstream end portion of a rotational flow amplification section. A downstream end portion of the rotational flow amplification section is engaged with an upstream end portion of a flow outlet section. The rotational assembly housing has an interior space extending along a centerline axis of the rotational assembly housing. The rotational assembly is disposed within the interior space of the rotational assembly housing. The rotational assembly and the rotational assembly are jointly configured for causing the rotational axis to extend colinearly with the centerline longitudinal axis of the rotational assembly housing.Type: GrantFiled: June 9, 2023Date of Patent: April 9, 2024Assignee: Vortex Pipe Systems LLCInventors: Paul Wayne Schmidt, Avijit Ghosh

Publication number: 20240067588Abstract: A method for purifying 1-hexene is disclosed. The method can include contacting a first stream containing 1-hexene and 2-ethyl-1-butene with an isomerization catalyst containing an comprising an alumina, silica-alumina, a zeolite, or an ion exchange resin, or any combinations thereof, under conditions sufficient to selectively isomerize at least a portion of 2-ethyl-1-butene into 3-methyl-2-pentene and form a second stream containing 1-hexene and 3-methyl-2-pentene, and separating the second stream into a third stream containing 1-hexene and a fourth stream containing 3-methyl-2-pentene.Type: ApplicationFiled: December 20, 2021Publication date: February 29, 2024Inventors: Shahid Azam, Abdulmajeed Mohammed Al-Hamdan, Mohammed Fahad Al-Anazi, Bander Bawareth, Ashim Kumar Ghosh, Debashis Chakraborty, Somak Paul, Rajan V.

Patent number: 11697997Abstract: A turbine for a turbo-machine is proposed in which, at a gas inlet for a turbine wheel, vanes extend from a nozzle ring though slots in a shroud. The nozzle ring and shroud are relatively rotatable about a rotational axis of the turbine by at least 0.1 degrees. In use, the nozzle ring and shroud are relatively rotated to bring one side of the vane into close contact with one surface of the slot, to inhibit leakage of gas between the vane and the slot surface. For this purpose the respective surfaces of the nozzle and slot can be configured to closely conform to each other. If there is differential thermal expansion of the shroud and nozzle ring, the nozzle ring and shroud can relatively rotate, to withdraw the vane from the edge of the slot to relieve the pressure between them.Type: GrantFiled: April 25, 2022Date of Patent: July 11, 2023Assignee: Cummins Ltd.Inventors: Matthew William Edwards, Karl Conlon, Simon David Moore, Christopher Parry, Andrew Sullivan, Paul Ghosh, Mark R. Holden, George E. Sandford, Nandakishore Arcot Madhusudan, Stephen David Hughes, Christopher J. Shaw

Patent number: 11629605Abstract: A turbine wheel consists of a first shroud component and a second bladed disc component. The shroud component comprises a shroud structure, a hub structure and a spoke formed integrally therewith and extending between the shroud structure and the hub structure. The bladed disc component comprises a hub member having inner and outer rims, turbine blades disposed on the outer rim, and at least one receiving zone for receiving the spoke, said at least one receiving zone extending radially between the inner and outer rims. The shroud component and the bladed disc component are connected and thus provide the turbine wheel with a shrouded portion. A shrouded turbine wheel can therefore be conveniently assembled starting from at least two components. Further, these components have simplified geometries for easy manufacture, for example using a casting technique, while the overall mechanical performance of the turbine is preserved or improved.Type: GrantFiled: March 28, 2019Date of Patent: April 18, 2023Assignee: Cummins LTDInventors: Henry Carr, Paul Ghosh
