Publication number: 20230228426Abstract: The fireplace includes a hearth suspended on a support. The hearth is defined laterally by a peripheral wall that is equipped with at least one combustion air inlet. There is a discharge pipe for discharging the combustion gases, that includes a bottom portion secured to a top part of the hearth, and a top portion opposite the bottom portion. The fireplace also includes at least one combustible fluid burner that is arranged in the hearth opposite at least one air inlet and a combustible fluid supply column that extends between a first end connected to a combustible fluid source and a second end connected to at least one burner. The supply column passed down through the discharge pipe from its top portion to its bottom portion and opens in the hearth in order to convey the combustible fluid from the combustible fluid source to at least one burner.Type: ApplicationFiled: October 22, 2020Publication date: July 20, 2023Inventors: Dominique IMBERT, Alexis GUY, Sylvain RAYMOND

Patent number: 10836616Abstract: A crane includes a luffing jib and a lifting cylinder having a cylinder body and a movable rod hinged on the jib to displace the jib in lifting motion and in lowering motion, and a locking device adapted to cooperate with the lifting cylinder to mechanically lock the rod in a deployed holding position and block the jib in a raised holding configuration. The crane further includes a spacer hinged on the jib and supporting a stop, the spacer pivotable between a release position in which the spacer is shifted, allowing the movable rod to be freely displaced, and a locking position in which the spacer is folded so that the stop is capable of abutting on a bearing surface in a ball jointed connection with the cylinder body, to fixedly hold the movable rod in the deployed holding position.Type: GrantFiled: October 9, 2018Date of Patent: November 17, 2020Assignee: Manitowoc Crane Group FranceInventors: Sylvain Raymond, Lotfi Bouskine, Gabriel Fraisse, Sylvain Brunet, Anthony Champcenest

Patent number: 7991023Abstract: A multi-band (multi-color) multiwavelength mode locked laser diode is provided by dynamic phase compensation of a quantum dot active medium. The laser diode is provided with a PIN diode structure where the active medium consists of a plurality of layers of quantum dots such as those produced by self-assembly from known chemical beam epitaxy methods. The multiplicity of bands may be produced by AC Stark splitting, frequency selective attenuation, or by the inclusion of multiple different layers having different, respective, peak ASE emissions. Dispersion compensation within laser facets, waveguides, and the optically active media permit the selection of a fixed dispersion within the cavity. A dynamic group phase change induced by the AC Stark effect permits compensation of the fixed dispersion sufficiently to produce an intraband mode-locked laser. Even interband mode locking was observed.Type: GrantFiled: September 25, 2009Date of Patent: August 2, 2011Assignee: National Research Council of CanadaInventors: Jiaren Liu, Zhenguo Lu, Sylvain Raymond, Philip Poole, Pedro Barrios, Daniel Poitras

Patent number: 7769062Abstract: Methods and devices for providing a multiwavelength laser which may be used for multicasting and other optical communications uses. The present invention provides a quantum dot based multiwavelength laser with a monolithic gain block. The Fabry-Perot gain block has both upper and lower InP cladding layers. The laser system has a middle quantum dot layer with multiple stacked layers of InAs quantum dots embedded in InGaAsP. When provided with a CW injection current, the laser system produces an output spectra with equally spaced multiple emission peaks. With an input optical data signal applied to the laser system, the laser system duplicates the data in the input signal across multiple different wavelengths.Type: GrantFiled: March 20, 2008Date of Patent: August 3, 2010Assignee: National Research Council of CanadaInventors: Zhenguo Lu, Jiaren Liu, Sylvain Raymond, Philip Poole, Pedro Barrios, Daniel Poitras

Patent number: 7155907Abstract: An electro-hydraulic system for operating a cooling fan and providing hydraulic fluid to a power steering system of the vehicle includes a hydraulic pump unit including first and second fixed displacement pumps and a common drive shaft for these pumps. A hydraulic fluid reservoir is connected to the inlet of each of the pumps. A priority valve is operatively connected to the outlet of the first pump and has an outlet connectible to the power steering system. This valve also has a second outlet connectible to a hydraulic motor for the cooling fan. This valve is arranged to provide a constant flow of hydraulic fluid to the power steering system. A hydraulic line connects an outlet of the second pump to the hydraulic motor. Hydraulic fluid flow through this line is combined with hydraulic fluid flow from the first pump to drive the motor.Type: GrantFiled: March 22, 2005Date of Patent: January 2, 2007Inventors: Yvon Clarence Desjardins, Sylvain Raymond Côté, Phillippe Louis Doutre, James Edward Yetter
