Publication number: 20220146034Abstract: A fluid system can have a water hammer arrestor including a resilient insert having an outer surface. The resilient insert can be operable to dampen a pressure spike in the fluid that exceeds a static pressure range, providing effective water hammer arrestment that without the resilient insert, would have occurred in a flowing fluid with the pressure spike. The static pressure range can be up to about 100 psig.Type: ApplicationFiled: April 23, 2020Publication date: May 12, 2022Inventors: Kenneth A. Cunefare, Nathaniel R.

Publication number: 20220113091Abstract: Setter plates are fabricated from Li-stuffed garnet materials having the same, or substantially similar, compositions as a garnet Li-stuffed solid electrolyte. The Li-stuffed garnet setter plates, set forth herein, reduce the evaporation of Li during a sintering treatment step and/or reduce the loss of Li caused by diffusion out of the sintering electrolyte. Li-stuffed garnet setter plates, set forth herein, maintain compositional control over the solid electrolyte during sintering when, upon heating, lithium is prone to diffuse out of the solid electrolyte.Type: ApplicationFiled: December 17, 2021Publication date: April 14, 2022Inventors: Sriram IYER, Tim Holme, Niall DONNELLY

Publication number: 20220053008Abstract: A threat protection system provides for detecting links in a document and analyzing whether one of the detected links is a malicious link that may direct a user of the document to a malicious universal resource locator (URL). In one implementation of the described technology, when a user selects a link in a document, a link activation module calls a threat protection client module that performs a reputation check for the link. If the selected link is malicious, the threat protection client module sends a URL of a warning page to the link activation module.Type: ApplicationFiled: October 28, 2021Publication date: February 17, 2022Inventors: Varagur Karthikeyan Sriram IYER, Willson Kulandai Raj DAVID, Vinayak GOYAL, Matthew Bryan JEFFRIES
