Patent number: 10692717Abstract: A method for defining thin film layers on a surface of a substrate includes exposing the surface of the substrate to a first precursor via a first plasma to allow the first precursor to be absorbed by the surface of the substrate. A second precursor that is different from the first precursor is applied to the surface of the substrate via a second plasma. The second precursor is a Carbon dioxide precursor that releases sufficient oxygen radicals to react with the first precursor to form an oxide film layer on the surface of the substrate.Type: GrantFiled: July 1, 2019Date of Patent: June 23, 2020Assignee: Lam Research CorporationInventors: Douglas Walter Agnew, Ishtak Karim

Patent number: 9796823Abstract: Films suitable for shrink film applications are disclosed comprising at least one heterogeneous ethylene interpolymer having a short chain branching distribution profile index, DPISCB, that satisfies the formula: ?1?DPISCB?1. The at least one heterogeneous ethylene interpolymer has a density from about 0.911 g/cm3 to about 0.942 g/cm3, a melt index from about 0.2 dg/min to about 3.5 dg/min and is produced using an in-line Ziegler-Natta catalyst. Additional embodiments include shrink films prepared from blends of at least one heterogeneous ethylene interpolymer and at least one high pressure ethylene polymer. The disclosed shrink films have improved puncture strength and machine direction shrink tunnel shrink force relative to control shrink films of the same composition but the control heterogeneous ethylene interpolymer, produced with a batch Ziegler-Natta catalyst, has a DPISCB greater than 1.0.Type: GrantFiled: July 7, 2016Date of Patent: October 24, 2017Assignee: NOVA Chemicals (International) S.A.Inventors: XiaoChuan Wang, Douglas Walter Checknita, John Leonard Bayley

Patent number: 9617994Abstract: A sliding vane, positive displacement pump is provided which includes a dual mechanical seal that protects against leakage from a pump chamber while also reducing slip across rotor end faces. The dual mechanical seal may be formed as a cartridge seal that is readily demountable from the pump for replacement and service, and is retrofittable to existing pumps to improve the performance thereof. The pump may integrally include a dual mechanical seal, or the mechanical seal assembly may be provided for use by itself or in combination with a replaceable head ring that can be installed on existing pumps for repair thereof or for a retrofit upgrade of such existing pump.Type: GrantFiled: April 17, 2015Date of Patent: April 11, 2017Assignee: Delaware Capital Formation, Inc.Inventors: Michael Douglas Walters, Michael Thomas Mitchell

Publication number: 20150347610Abstract: Methods and apparatus for modifying a plurality of markup language files are disclosed. In general, web pages are renamed as they are brought in to a document review application, and a data structure is created that associates the old name of each web page with the new name of each web page. Then, all of the links in the web pages are modified to also use the new names. As a result, users of the document review application may review the web pages with functional links.Type: ApplicationFiled: June 3, 2014Publication date: December 3, 2015Applicant: kCura CorporationInventors: Gaurav Vempati, Douglas Walter Stevens
