Patent number: 11698169Abstract: A vessel for the transport of liquefied gas has a hull, a cargo storage tank arranged in the hull for storing liquefied gas and an engine to propel the ship. A compressor has a compressor inlet connected to a vapour space of the at least one cargo storage tank for receiving boil-off gas at a first pressure and a compressor outlet for supplying pressurized boil-off gas to the at least one engine at a second pressure exceeding the first pressure. A boil-off gas recovery system is provided for recovery of boil off gas. The boil-off gas recovery system has a cooling section with a cooling section inlet connected to the compressor outlet to recondense at least part of the pressurized boil-off gas and a boil-off gas storage tank having a boil-off gas storage tank inlet connected to the cooling section outlet for storing the recondensed pressurized boil-off gas.Type: GrantFiled: December 19, 2017Date of Patent: July 11, 2023Assignee: SHELL USA, INC.Inventors: Mark Andrew Hodgson, Stephen Andrew Brown

Publication number: 20220194533Abstract: A method for the reduction of ship fuel consumption through the optimisation of vessel draft, speed and trim using historical vessel data. Historical global, online data, is collected for multiple vessel operating parameters associated with its previous voyages. After initial filtering and cleaning of the gathered data, a process of analysing the data to determine the optimum draft, speed and trim for the vessels' given speed is described. The determined optimum draft, speed and trim values are then presented to the Captain or an automatic draft and trim optimisation system for the current draft and trim to be adjusted. This application therefore discloses a method for analysing historical vessel data to provide advice on optimum draft, trim and speed. A method for predicting the achievable fuel savings and recording the fuel savings achieved is also disclosed.Type: ApplicationFiled: February 3, 2020Publication date: June 23, 2022Inventors: Ivan STOJANOVIC, Stephen Andrew BROWN, Christopher Debesh NEEDHAM, Bernhard GODDERIDGE, James Matthew HELLIWELL

Patent number: 10537178Abstract: A furniture member may include a stationary seatback frame, a seat bottom assembly, a legrest mechanism, and a backrest support spring. The seat bottom assembly is movable relative to the seatback frame between a nominal position and a tilt position. The legrest mechanism is movable among a retracted position, a first extended position and a second extended position. A portion of the legrest mechanism contacts the seat bottom assembly when the legrest mechanism is in the first extended position and pushes the seat bottom assembly from the nominal position to the tilt position as the legrest mechanism moves from the first extended position to the second extended position. The backrest support spring includes a first end attached to the seatback frame and a second end attached to the seat bottom assembly and movable with the seat bottom assembly relative to the seatback frame.Type: GrantFiled: April 7, 2017Date of Patent: January 21, 2020Assignee: La-Z-Boy IncorporatedInventors: Richard E.

Patent number: 8948659Abstract: A unit for use with a removable toner cartridge of an image forming device according to one example embodiment includes a housing having a reservoir for holding toner. An inlet port is positioned to receive toner from the toner cartridge. The inlet port is connected to the reservoir to allow the toner received from the toner cartridge to enter the reservoir. A shutter is slidably movable between a closed position and an open position. A biasing member biases the shutter toward the closed position. The shutter includes a first engagement surface positioned to receive a first engagement member of the toner cartridge to begin to open the shutter as the toner cartridge is inserted in the image forming device. The shutter also includes a second engagement surface positioned to receive a second engagement member of the toner cartridge to move the shutter a remaining distance to the open position.Type: GrantFiled: April 30, 2012Date of Patent: February 3, 2015Assignee: Lexmark International, Inc.Inventors: Ronald Willard Baker, Stephen Andrew Brown, David Francis Carter, Michael Craig Leemhuis

Patent number: 8948660Abstract: A toner cartridge according to one example embodiment includes a housing having a reservoir for holding toner. An outlet port is positioned on the front of the housing for transferring toner from the reservoir to the developer unit through an inlet port on the developer unit. A first engagement member projecting from the front of the housing is positioned to provide an initial force to begin to open a shutter on the inlet port of the developer unit as the toner cartridge is inserted in the image forming device. A second engagement member projecting from the front of the housing is spaced toward one of the sides of the housing from the first engagement member and positioned to provide a force to continue to open the shutter on the inlet port of the developer unit as the toner cartridge is inserted further in the image forming device.Type: GrantFiled: April 30, 2012Date of Patent: February 3, 2015Assignee: Lexmark International, Inc.Inventors: Ronald Willard Baker, Stephen Andrew Brown, Michael Craig Leemhuis, David Lee Merrifield

Patent number: 8644725Abstract: An end seal for use in an image forming apparatus that provides increased contact pressure using projecting ribs at nip locations formed between an end of a roll and the ends of other components such as a doctor blade or flap seal and lower contact pressure along the end of the roll. Contact pressure may be varied by changing the thickness along portions of the projecting ribs or the use of transverse ribs between each of the projecting ribs and a second surface of the end seal.Type: GrantFiled: May 18, 2011Date of Patent: February 4, 2014Assignee: Lexmark International, Inc.Inventors: Stephen Andrew Brown, Nicholas Fenley Gibson
