Patent number: 10668454Abstract: The preparation of an oxidative dehydrogenation catalyst comprising Mo, V, Nb and Te using a hydrothermal step. In some embodiments, the activity and reproducibility of the catalyst is improved by conducting the hydrothermal step while permitting gaseous products to leave the reactor. In some instances a condenser may be upstream of the outlet of the reactor.Type: GrantFiled: October 10, 2017Date of Patent: June 2, 2020Assignee: NOVA Chemicals (International) S.A.Inventors: Vasily Simanzhenkov, Xiaoliang Gao, David Jeffrey Sullivan

Publication number: 20200160753Abstract: A device and system for simulating normal and disease state cardiovascular functioning, including an anatomically accurate cardiac simulator for training and medical device testing. The system and device uses pneumatically pressurized chambers to generate ventricle and atrium contractions. In conjunction with the interaction of synthetic valves, which simulate mitral and aortic valves, the system is designed to generate pumping action that produces accurate volume fractions and pressure gradients of pulsatile flow, duplicating that of a human heart. Through the use of a control unit and sensors, one or more parameters, such as flow rates, fluidic pressure, and heart rate, may be automatically controlled, using feedback loop mechanisms to adjust parameters of the hydraulic system to simulate a wide variety of cardiovascular conditions including normal heart function, severely diseased or injured heart conditions, and compressed vasculature, such as hardening of the arteries.Type: ApplicationFiled: September 20, 2019Publication date: May 21, 2020Inventors: Chandramouli Sadasivan, Baruch B.

Patent number: 10576461Abstract: A catalyst for oxidative dehydrogenation (ODH) of ethane with an empirical formula Mo—V—Te—Nb—Pd—O produced using a process comprising impregnation of the Pd component on the surface of the catalyst following a calcination step using a Pd compound free of halogens. The resulting catalyst can be used in both diluted and undiluted ODH processes and shows higher than expected activity without any loss of selectivity.Type: GrantFiled: June 8, 2017Date of Patent: March 3, 2020Assignee: NOVA Chemicals (International) S.A.Inventors: Vasily Simanzhenkov, Xiaoliang Gao, David Jeffrey Sullivan, Leonid Modestovich Kustov, Aleksey Victorovich Kucherov, Elena Dmitrievna Finashina

Patent number: 10294952Abstract: Arrangements for promoting the restriction of fluid flow along a shaft via providing a deformable ring member in an annulus between the shaft and housing. In an initial general condition, the deformable ring member permits free fluid flow in a general direction along the shaft while in a second, constricted condition, the deformable ring closes or blocks a gap or clearance normally conducive to free fluid flow to thereby restrict fluid flow. An actuation medium, which can take any of a very wide variety of forms, preferably promotes constriction of the deformable ring member directly or indirectly.Type: GrantFiled: February 14, 2014Date of Patent: May 21, 2019Assignee: CURTISS-WRIGHT ELECTRO-MECHANICAL CORPORATIONInventors: David Jeffrey Janocko, Charles David Bice

Patent number: 10108357Abstract: Embodiments of a row address cache circuit are disclosed that may allow the determination the number of times a row address is used to access a dynamic memory. The row address cache circuit may include a memory, first and second pluralities of counters, and a control circuit. The control circuit may be configured to receive a row address and store the row address in an entry of the memory when the row address has not been previously stored. When the row address has been previously stored in an entry of the memory, the control circuit may be configured to change a value of a counter of the first plurality of counters corresponding the entry. The control circuit may be further configured to change a value of each counter of the second plurality of counters after a pre-determined time interval has elapsed, and initiate a refresh of the dynamic memory.Type: GrantFiled: May 3, 2016Date of Patent: October 23, 2018Assignee: Oracle International CorporationInventors: David Jeffrey, Clement Fang, Neil Duncan, Heechoul Park, Lik Cheng, Gregory F.
