Patent number: 11968893Abstract: Disclosed are electroluminescent devices that comprise organic layers that contain certain organic compounds containing one ore more pyrimidine moieties. The organic compounds containing one ore more pyrimidine moieties are suitable components of blue-emitting, durable, organo-electroluminescent layers. The electroluminescent devices may be employed for full color display panels in for example mobile phones, televisions and personal computer screens.Type: GrantFiled: March 18, 2022Date of Patent: April 23, 2024Assignee: UDC Ireland LimitedInventors: Thomas Schafer, Patrice Bujard, Jonathan Rogers, Kristina Bardon

Publication number: 20200132366Abstract: Systems and methods are provided for the production of liquefied natural gas. At least one of the systems may include a plurality of compression assemblies in fluid communication with a precooler assembly. One compression assembly may be a part of a precooling loop and may include at least one compressor driven by a variable or fixed speed motor. Another compression assembly may be part of a liquefaction loop and may include at least one pair of compressors, each compressor driven by a respective turbine. The liquefaction loop may be fluidly coupled to a main heat exchanger utilized to liquefy at least a portion of a feed gas stream containing natural gas flowing through the main heat exchanger, thereby producing liquefied natural gas.Type: ApplicationFiled: March 22, 2018Publication date: April 30, 2020Inventors: Patrice BARDON, Georg NIENHAUS

Patent number: 10480852Abstract: A liquefaction system and method for producing liquefied natural gas (LNG) is provided. The liquefaction system may include a heat exchanger to cool natural gas to LNG, a first compressor to compress and combine first and second portions of a single mixed refrigerant from the heat exchanger, a first cooler to cool the single mixed refrigerant from the first compressor to a first liquid phase and a gaseous phase, and a first liquid separator to separate the first liquid phase from the gaseous phase. The liquefaction system may also include a second compressor to compress the gaseous phase, a second cooler to cool the compressed gaseous phase to a second liquid phase and the second portion of the single mixed refrigerant, a second liquid separator to separate the second liquid phase from the second portion of the single mixed refrigerant, and a pump to pressurize the first liquid phase.Type: GrantFiled: December 3, 2015Date of Patent: November 19, 2019Assignee: DRESSER-RAND COMPANYInventors: Patrice Bardon, Hongpyo Kim, Matthew Romeike

Patent number: 9488187Abstract: A sealing system for process gas leakage from a turbomachine casing is provided. The sealing system may include a seal assembly housing coupled to or integral with the turbomachine casing. The seal assembly housing defines a bore configured to receive a rotary shaft and a sealing assembly. The sealing assembly includes a plurality of carbon rings mounted circumferentially about the rotary shaft. The plurality of carbon rings may include an inboard carbon ring configured to prevent flow of a separation gas inboard of the barrier seal, an outboard carbon ring configured to prevent flow of contaminates into the seal assembly housing, and an intermediate carbon ring interposed between the inboard carbon ring and outboard carbon ring. A pressure differential is maintained across the inboard carbon ring, such that the separation gas is prevented from flowing inboard across the inboard carbon ring by a residual portion of a seal gas.Type: GrantFiled: February 4, 2014Date of Patent: November 8, 2016Assignee: Dresser-Rand CompanyInventors: Patrice Bardon, Raphael Bridon, Wee Sen Ng, William Runyan
