Patent number: 11675812Abstract: Methods and apparatuses are described for synchronization of metadata between databases in a cloud computing environment. A computing device identifies jobs that synchronize metadata from a first database instance to a second database instance, each job comprising synchronization tasks for a different portion of the metadata. The computing device determines a count of the synchronization tasks for each job. The computing device allocates each job to a first queue where the count of the synchronization tasks for the job is below a threshold value, and allocates the synchronization tasks for each job to a second queue where the count of the synchronization tasks for the job is at or above the threshold value. The computing device executes the jobs in the first queue and executes the synchronization tasks in the second queue to synchronize the corresponding metadata to the second database instance.Type: GrantFiled: September 29, 2022Date of Patent: June 13, 2023Assignee: FMR LLCInventors: Vignesh Prasad Veera Prasad, Divakar Sugumar, Raghu Kumar Thukral, Sachin Samuel

Patent number: 11635265Abstract: A bolted hinge assembly is provided for a waterbox cover (a “waterbox hinge assembly”). The waterbox hinge assembly generally does not require welding on the waterbox cover or the heat exchanger in an HVAC system (“HVAC unit” hereinafter). Further, the waterbox hinge assembly may be installable to the HVAC unit without removing the heat exchange fluids (e.g., water, refrigerant, etc.) from the HVAC unit. In some cases, the waterbox hinge assembly can be installed on an HVAC unit without removing any bolts from the waterbox cover. Once installed, the waterbox hinge assembly can be left in place so that it can be reused anytime the HVAC unit is serviced.Type: GrantFiled: February 4, 2019Date of Patent: April 25, 2023Assignee: TRANE INTERNATIONAL INC.Inventors: Steven E. Wolfgram, Daoud A. Jandal, Bradley S. Wickersham, Fred Eickstaedt, James M. McCool, Raymond S. Schafer, Ronald E. Schlicht, Robert A. Harris, Steven E. Meloling, Raghu Kumar, Kishore Prabakaran

Patent number: 8017374Abstract: The present invention relates to a novel process for decolorization of colored effluents. More particularly it relates to a process for decolorization of colored effluents of textile mills, dye-making industries, paper and pulp industries and molasses spent wash from alcohol distilleries using an unidentified white-rot marine fungus NIOCC #2a isolated from mangrove wood and deposited on Sep. 7, 2004 in the microbial type culture collection (MTCC) of the Institute of Microbial Technology, Chandigarh, India, under the accession number MTCC 5159. Further, this invention relates to decolorization of these effluents using the fungus directly, its cell-free culture supernatant or immobilized fungus or extracellular polymeric substances produced by the fungus. Furthermore, the decolorization of effluents can be carried out from 30° C. to 60° C. and at pH 3 to 6. The decolorization of various colored effluents occurs in the presence of sea water with 25 parts per thousand salinity.Type: GrantFiled: February 12, 2005Date of Patent: September 13, 2011Assignee: Council of Scientific and Industrial ResearchInventors: Chandralata Raghu Kumar, Donna Trella D'Souza Ticlo

Publication number: 20080073042Abstract: The present invention provides a process for enzymatic deinking of office waste paper inclusive of xerographic and inkjet-printed paper printed with non impact and non dispersible ink using the cell free culture supernatant of Vibrio alginolyticus or immobilized cells of the same bacterium having the accession number NIO/DI/32 and deposited at ARS Patent Culture Collection, USA, under the Number NRRL-B-30638. Further, this invention relates to decolorization of office waste paper pulp within 72 h after contacting the said enzymes from the said bacterium in the pulp of 3-12% consistency in seawater. Decolorization is achieved by using extracellular enzymes produced by the bacterium NIO/DI/32 grown in nutrient broth supplemented with starch or Tween 80.Type: ApplicationFiled: March 30, 2006Publication date: March 27, 2008Inventors: Raghu Kumar Chandralata, Chellandi Mohandass, Antonio Mascarenhas, Vijay Kumar Kannoujia
