Patent number: 11118475Abstract: A turbine shroud segment has a body having a radially outer surface and a radially inner surface extending axially between a leading edge and a trailing edge and circumferentially between a first and a second lateral edge. A first serpentine channel is disposed axially along the first lateral edge. A second serpentine channel is disposed axially along the second lateral edge. The first and second serpentine channels each define a tortuous path including axially extending passages between a front inlet proximate the leading edge and a rear outlet at the trailing edge of the body.Type: GrantFiled: January 23, 2020Date of Patent: September 14, 2021Assignee: PRATT & WHITNEY CANADA CORP.Inventors: Remy Synnott, Mohammed Ennacer, Chris Pater, Denis Blouin, Kapila Jain, Farough Mohammadi

Patent number: 10533454Abstract: A turbine shroud segment comprises a body having an upstream end portion and a downstream end portion relative to a flow of gases through the gas path. A core cavity is defined in the body and extends axially from the upstream end portion to the downstream end portion. A plurality of cooling inlets is defined in the upstream end portion of the body for feeding coolant in the core cavity. A plurality of cooling outlets is defined in the downstream end portion of the body for discharging coolant from the core cavity. Pedestals are provided in the core cavity.Type: GrantFiled: December 13, 2017Date of Patent: January 14, 2020Assignee: Pratt & Whitney Canada Corp.Inventors: Remy Synnott, Mohammed Ennacer, Chris Pater, Denis Blouin, Kapila Jain, Farough Mohammadi

Patent number: 10502093Abstract: A turbine shroud segment has a body extending axially between a leading edge and a trailing edge and circumferentially between a first and a second lateral edge. A core cavity is defined in the body and extends axially from a front end adjacent the leading edge to a rear end adjacent to the trailing edge. A plurality of cooling inlets and outlets are respectively provided along the front end and the rear end of the core cavity. A crossover wall extends across the core cavity and defines a row of crossover holes configured to accelerate the flow of coolant directed into the core cavity via the cooling inlets. The crossover wall is positioned to accelerate the coolant flow at the beginning of the cooling scheme where the shroud segment is the most thermally solicited.Type: GrantFiled: December 13, 2017Date of Patent: December 10, 2019Assignee: PRATT & WHITNEY CANADA CORP.Inventors: Remy Synnott, Mohammed Ennacer, Chris Pater, Denis Blouin, Kapila Jain, Farough Mohammadi

Patent number: 9782904Abstract: Apparatuses and methods for cutting a facestock on a liner. An anvil roller receives facestock on liner. A cutting roller, under a force, cuts facestock between the cutting roller and the anvil roller. At least one support roller supports the cutting roller and, optionally, the anvil roller, thereby distributing the force into two or more portions and/or subportions, in two or more directions. Apparatuses, methods and kits for preparing a cutting surface of a cutting roller in a facestock cutting apparatus, or for extending the usefulness of a cutting roller. An equalizer roller is provided in a position adjacent to the cutting roller. The equalizer roller has an equalizing surface having a hardness at least as hard as a hardness of the cutting surface. The cutting roller is rotated against the equalizer roller such that the cutting surface is equalized by the equalizing surface.Type: GrantFiled: February 29, 2016Date of Patent: October 10, 2017Assignee: ETI Converting EquipmentInventors: Francois Bayzelon, Eric Ouellet, Denis Blouin, Jean-Francois Poirier

Patent number: 6365836Abstract: A cross web core in a high performance data cable maintains geometric stability between plural twisted pair transmission media and between each twisted pair and the cable jacket. The cross web core may further isolate twisted pairs from each other by including conductive or magnetically permeable materials. By so doing, loss, impedance and crosstalk performance are improved.Type: GrantFiled: June 30, 1999Date of Patent: April 2, 2002Assignee: Nordx/CDT, Inc.Inventors: Denis Blouin, Jacques Cornibert, Jörg-Hein Walling
