Patent number: 11261933Abstract: A pendulum damping device including a support that rotates about an axis, at least one pendulum body and at least one rolling member guiding the movement of the pendulum body relative to the support, the rolling member engaging with at least one rolling track rigidly connected to the support and with at least one rolling track rigidly connected to the pendulum body. The rolling member includes a first part defining a first axial end, a second part defining a second axial end, and a resilient element arranged in the rolling member so as to axially separate these two parts so that the rolling member exerts an axial clamping force on one of the pendulum body and the support during the movement of the pendulum body relative to the support.Type: GrantFiled: September 6, 2018Date of Patent: March 1, 2022Assignee: VALEO EMBRAYAGESInventors: Matthieu Malley, Olivier Fafet, Antoine Vigreux, Didier Couvillers, David Salvadori, Franck Cailleret, Adrien Nerriere, Jonathan Rost

Publication number: 20200378487Abstract: A turbine wheel for a hydrokinetic torque converter. The turbine wheel is rotatable about a rotational axis and comprises a substantially annular turbine shell member coaxial with the rotational axis, and a plurality of turbine blade members axially extending from the turbine shell member. The turbine wheel is a single-piece component such that the turbine blade members are unitarily formed with the turbine shell member. The turbine wheel (22) is made by an additive manufacturing process from a polymeric material.Type: ApplicationFiled: August 13, 2020Publication date: December 3, 2020Inventors: Subramanian JEYABALAN, Alexandre DEPRAETE, Jean-François BISSON, David SALVADORI, Adrien PEDUZZI

Patent number: 10366454Abstract: Systems and methods are provided for processing derivative product orders at an exchange. Traders provide derivative product order risk data to the exchange. The order risk data may include maximum delta, gamma and/or vega utilization values for derivative product contracts based on the same underlying product. Before executing a trade, a match system analyzes the trader's current utilization state and the utilization that would result after the trade. The match system may then execute all or a portion of the trade.Type: GrantFiled: October 19, 2018Date of Patent: July 30, 2019Assignee: Chicago Mercantile Exchange Inc.Inventors: David Salvadori, John Falck, Charlie Troxel, Jr., James Farrell, Agnes Shanthi Thiruthuvadoss, Arjuna Ariathurai, Scott Johnston

Patent number: 10217165Abstract: Methods and systems for an exchange to handle variable derivative product order prices are disclosed. The price of a derivative product order (bid or offer) is updated based on changes in the price of a related underlying product. Price determination variable(s), such as delta and gamma, are used to determine the price of the order. The exchange may periodically recalculate the price without requiring the trader to transmit additional information to the exchange.Type: GrantFiled: January 22, 2018Date of Patent: February 26, 2019Assignee: Chicago Mercantile Exchange Inc.Inventors: Scott Johnston, John Falck, Charlie Troxel, Jr., James W.
