Patent number: 10737237Abstract: A composition capable of removing chlorides from a gaseous stream and a process of using same. The compositions have sufficient chloride capacity, offer comparable creation of green oil, and have sufficient structural integrity to be utilized as sorbents in a chloride removal process. Generally, the compositions include a first zinc carbonate, a second zinc carbonate different than the first zinc carbonate and an alumina material. The composition has been cured at a temperature between about 149 to 399° C. The first zinc carbonate may comprise hydrozincite and the second zinc carbonate may comprise smithsonite.Type: GrantFiled: February 2, 2018Date of Patent: August 11, 2020Assignee: UOP LLCInventors: Gregory Gajda, Mark G.

Patent number: 8173211Abstract: A method of production of carbon nanoparticles comprises the steps of: providing on substrate particles a transition metal compound which is decomposable to yield the transition metal under conditions permitting carbon nanoparticle formation, contacting a gaseous carbon source with the substrate particles, before, during or after said contacting step, decomposing the transition metal compound to yield the transition metal on the substrate particles, forming carbon nanoparticles by decomposition of the carbon source catalysed by the transition metal, and collecting the carbon nanoparticles formed.Type: GrantFiled: July 16, 2003Date of Patent: May 8, 2012Assignee: Cambridge University Technical Services LimitedInventors: Milo Sebastian Peter Shaffer, Alan H. Windle, Brian F. G. Johnson, Junfeng Geng, Douglas Shephard, Charanjeet Singh

Patent number: 7694143Abstract: A method of and system for collecting an electronic signature for an electronic record stored in a database. In one embodiment the method comprises automatically creating an electronic record from data stored in a plurality of different database tables in response to the occurrence of a predetermined event; storing an instance of the electronic record in a common repository of electronic records that provides an audit trail that cannot be altered or disabled by users of the system; executing a rule associated with the electronic record to determine whether an electronic signature is required to connote review and/or approval of the electronic record; and if execution of the rule results in a determination that an electronic signature is required, marking the instance of the electronic record as unsigned and initiating a request to collect the required electronic signature.Type: GrantFiled: December 8, 2003Date of Patent: April 6, 2010Assignee: Oracle International CorporationInventors: Srikanth Karimisetty, Srinivasulu Puri, Charanjeet Singh, Ravindra Akella, Savita Durgada

Patent number: 7650512Abstract: A method of and system for searching unstructured data stored in a database. In one embodiment the method comprises storing a plurality of electronic records in a common repository of electronic records in the database that provides an audit trail that cannot be altered or disabled by users of the system where each electronic record comprises unstructured data stored in a character large-object (CLOB) format in a column of a table of the database; creating a security protocol that protects the electronic records against unauthorized access; and creating a query designed to identify electronic records in the database that meet criteria designated in the query. The method further comprises modifying the query in accordance with the security protocol to create a modified query prior to executing the query and running the modified query against the unstructured data.Type: GrantFiled: December 8, 2003Date of Patent: January 19, 2010Assignee: Oracle International CorporationInventors: Srikanth Karimisetty, Srinivasulu Puri, Charanjeet Singh, Ravindra Akella, Savita Durgada

Publication number: 20050108211Abstract: A method of and system for searching unstructured data stored in a database. In one embodiment the method comprises storing unstructured data in a column of a database table; allowing a user to identify elements in the unstructured data as indexed elements; creating an intermediate index into the unstructured data from the identified elements; and allowing a user to create queries on the unstructured data using the indexed elements. In some implementations of this embodiment the unstructured data comprises a well-formed XML document stored within a column of a database table. Also, in some implementations the unstructured data is part of an electronic record stored in a common repository of electronic records that provides an audit trail that cannot be altered or disabled by users of the database.Type: ApplicationFiled: December 8, 2003Publication date: May 19, 2005Applicant: ORACLE INTERNATIONAL CORPORATION, A California corporationInventors: Srikanth Karimisetty, Srinivasulu Puri, Charanjeet Singh, Ravindra Akella, Savita Durgada
