Patent number: 12134056Abstract: Improvements to filtration and vessels such as for filtration and coalescing of gas streams are shown. A filter element with a partial treated region and untreated region such as providing different surface energies or other filtration characteristics are provided. Various keying arrangements for compatibility and/or rotational locking are shown between the filtration vessel, a tubular coalescing baffle, and/or filter element. The tubular coalescing baffle also may include non-louvered pore structure, which provides for more even flow in a two stage type filtration vessel to prevent premature exiting and reduction of flow velocities along the second stage, and/or may additionally or alternatively include drainage apertures such as drain slot formed along a gravitational bottom or otherwise to facilitate additional drainage of coalesced liquid as opposed to letting such liquid be forced through fluid velocity toward the open end of the tubular baffle.Type: GrantFiled: May 24, 2021Date of Patent: November 5, 2024Assignee: Parker-Hannifin CorporationInventors: Daniel M. Cloud, Stephen Gregory Jeane, Jack David Burns

Publication number: 20240116777Abstract: A method and apparatus is disclosed for separating an amount of an amphiphilic contaminant substance such as PFAS from water. The method comprising the steps of admitting the water which contains the substance into a flotation cell chamber, and then introducing a flow of gas thereinto. The gas is introduced by several different apparatus options for efficient aeration of the chamber, depending on the water being treated. The introduced gas produces a froth layer which is formed at, and which rises above, an interface with the contents of the chamber. The froth layer includes an amount of water and also a concentrated amount of the contaminant substance when compared with its initial concentration. The process then involves collapsing and removing the froth layer, with several options for removing the PFAS from that liquid by re-flotation to reconcentrate the PFAS, or absorption onto a solid substrate material.Type: ApplicationFiled: February 2, 2022Publication date: April 11, 2024Inventor: David Burns

Publication number: 20240098492Abstract: During operation, an access point may provide a first WLAN and a second WLAN, where the first WLAN uses a WPA2-compatible authentication protocol and the second WLAN uses a WPA3-compatible authentication protocol. In response to an association request or a probe request associated with (or from) an electronic device, the access point may establish a connection with the electronic device using the first WLAN. Then, the access point may confirm, with a computer system, that a binding between a passphrase associated with the electronic device and the second WLAN exists. Alternatively, when the binding does not exist, the access point may establish the binding in the computer system. Next, the access point may perform a BSS transition of the electronic device from the first WLAN to the second WLAN.Type: ApplicationFiled: September 6, 2023Publication date: March 21, 2024Applicant: ARRIS Enterprises LLCInventors: Wei-Sheng Hsu, Yu-Ting Chang, Weichih Huang, Kuan-Hsun Peng, Weiguo Xie, Christopher Mohammed, Shannon Moyes Clark, Siddhartha Datta, David Burns
