Patent number: 11220636Abstract: A hydrocarbon-in-water purification system includes a high capacity hydrocarbon absorber stage having a high capacity hydrocarbon absorber material and an inlet configured to receive a hydrocarbon-in-water dispersion from a fuel system. A polishing hydrocarbon absorber stage is in liquid communication and downstream of the high capacity hydrocarbon absorber stage including polishing activated carbon. The high capacity hydrocarbon absorber material has a greater saturation capacity than the polishing activated carbon and the polishing activated carbon has a greater polishing capacity than the high capacity hydrocarbon absorber material. A method for controlling and managing the evacuation of water from the hydrocarbon-in-water purification system includes tracking the purification state of water volumes and the bed loading states of purification beds defined in the water filter.Type: GrantFiled: November 12, 2019Date of Patent: January 11, 2022Assignee: Donaldson Company, Inc.Inventors: Davis B.

Patent number: 11077748Abstract: A shutoff vent is disclosed. A main body has a first end and a second end. The main body defines a first opening towards the first end, a second opening towards the second end, and a mating port between the first opening and the second opening. The first opening and the second opening are in communication through the mating port to define a gas passageway. A translatable plug is disposed within the main body, and the gas passageway extends past the translatable plug. The translatable plug is configured to reversibly translate towards the second end to sealably obstruct the mating port. In some examples, the translatable plug is configured to translate towards the second end when force is applied to the translatable plug from the first end.Type: GrantFiled: February 17, 2017Date of Patent: August 3, 2021Assignee: Donaldson Company, Inc.Inventors: Michael J. Hebert, Alexandra M. Boyat, Daniel Dotzler, Joseph M. Block

Publication number: 20210106935Abstract: The current technology relates to substrate treatments, treated substrates, and filters. Treated substrates can have a treated surface that defines a pattern and/or gradient among untreated surface areas. A treated surface area can have a higher roll off angle for a 50 ?L water droplet when the surface is immersed in toluene that the untreated surface areas. Substrates can be treated by, for example, exposing a substrate surface and/or fibers to ultraviolet (UV) radiation. UV radiation can be applied to surfaces via a mask, lens, waveguide, reflector, as examples. UV radiation can be applied to surfaces at varying intensities, which can create a treatment gradient.Type: ApplicationFiled: February 14, 2019Publication date: April 15, 2021Inventors: Aflal Rahmathullah, Andrew J. Dallas, Stephen K. Sontag, Bradly G. Hauser, Davis B. Moravec, Vijay K. Kapoor, Matthew P. Goertz, Daniel L. Tuma, Warren E. Dammann, Michael J. Cronin, Mike J. Madsen, Stuti S. Rajgarhia, Charles S.

Publication number: 20210060456Abstract: The current technology relates to filter media configurations where the filter media has a surface with a treatment that that increases the roll off angle of the surface for a 50 ?L water droplet when the surface is immersed in toluene. Some example filter media has a fluted configuration, and some example filter media has multiple layers. Filter media having multiple layers can be single facer media, for example, where one layer is planar and another layer is fluted.Type: ApplicationFiled: February 14, 2019Publication date: March 4, 2021Inventors: Aflal Rahmathullah, Andrew J.

Publication number: 20210016214Abstract: The current technology relates to various filter elements configurations where a substrate layer defines a surface having a treatment. The treatment increases a roll off angle of the surface for a 50 water droplet when the surface is immersed in toluene. The filter element can have a housing and the substrate disposed in the housing. In some embodiments the substrate layer defines a plurality of pleats extending between pleat folds that form flow faces of the media. In some embodiments the substrate is incorporated into single facer media of a filter element. In some embodiments the substrate layer is incorporated in a filter element having a flow-by configuration. In some embodiments the substrate layer is incorporated in a filter element having a cross-flow configuration. Some embodiments relate to a vent. Some embodiments relate to a barrier assembly and/or a fuel filter element. Various other filter elements are described.Type: ApplicationFiled: February 14, 2019Publication date: January 21, 2021Inventors: Aflal Rahmathullah, Andrew J. Dallas, Brian R. Tucker, Daniel E.
