Publication number: 20240143931Abstract: Disclosed herein is a system that automatically correlates related instances of written feedback associated with a computer product to relevant telemetry data so that a performance and/or reliability issue associated with the computer product can be identified and fixed in a more efficient manner. The system applies a natural language processing model to instances of written feedback that have been received for the computer product to identify a cluster of instances of written feedback which describe the same issue. For each instance of written feedback in the cluster, the system uses an identification and a timestamp to retrieve a telemetry event log. The system analyzes the telemetry event logs to identify a common telemetry event. This effectively correlates meaningful written descriptions with common telemetry behavior(s). Information regarding this correlation is provided to a computing device of a user (e.g., a developer) tasked with examining the performance and/or reliability issue.Type: ApplicationFiled: October 26, 2022Publication date: May 2, 2024Inventors: Ryan Sung Jun BAE, Prachur BHARGAVA, Anjali S.

Patent number: 9321908Abstract: The present invention relates generally to a method for dispersing a dry cellulose ether powder in an aqueous solution without forming lumps using powder handling and mixing devices. The cellulose ethers can be cross-linked with an aldehyde cross-linker. An acid or partially neutralized acid is used to improve the solubility.Type: GrantFiled: April 22, 2013Date of Patent: April 26, 2016Assignee: HERCULES INCORPORATEDInventors: Prachur Bhargava, Konstantin A. Vaynberg

Patent number: 9321851Abstract: The present invention relates generally to water soluble polymer powder formulations, and more particularly, to a cellulose ether formulation which in powder form is suitable for direct addition to water-based systems to produce smooth, lump free solutions. The cellulose ethers are crosslinked with an aldehyde crosslinker and include a dry weak acid which slows hydrolysis of the hermiacetal linkage formed by the crosslinker. The selected acid does not adversely affect solubility stability.Type: GrantFiled: March 5, 2012Date of Patent: April 26, 2016Assignee: HERCULES INCORPORATEDInventors: Prachur Bhargava, Glen T. Carroll, Tuyen T. Nguyen, Kostantin A. Vaynberg

Publication number: 20150112000Abstract: The presently disclosed and claimed inventive concept(s) relates to a method for making a particular product comprising a nonionic synthetic associative (NSAT) rheology modifier and a dissolution promotion water soluble additive. The method comprising the steps of: (a) obtaining the NSAT theology modifier and the dissolution promotion water soluble additive; (b) melting the NSAT theology modifier and the dissolution promotion water soluble additive; (c) mixing the molten NSAT theology modifier and the dissolution promotion water soluble additive; and (d) producing the particulate product from step (c). The NSAT rheology modifier is selected from the group consisting of hydrophobically-modified ethoxylated urethane (HEUR), hydrophobically-modified polyethylene glycol (HMPEG), and hydrophobically-modified polyacetal-polyether (HMPAPE). The particulate product prepared from the method is incorporated into a waterborne paint formula.Type: ApplicationFiled: December 23, 2014Publication date: April 23, 2015Inventors: Prachur Bhargava, Paul C.
