Patent number: 12385440Abstract: An assembly for a turbomachine includes at least one turbine having a turbine disc with an internal bore and an annular cavity which is arranged upstream of the disc. The assembly further includes a fire safety system with a cooling device that supplies the cavity with cooling air via injection means. The fire safety system includes means that divide the annular cavity into first and second cavities. A cooling air speed is maintained at the outlet of the injection means and the cooling air in the first cavity is guided to the internal bore of the turbine disc. A diffuser co-operates with the injection means and an annular cover co-operates with the diffuser and covers first attachment members arranged in the cavity. A radially outer surface of the cover at least partially guides the cooling air at the outlet of the diffuser.Type: GrantFiled: July 7, 2022Date of Patent: August 12, 2025Assignee: SAFRAN HELICOPTER ENGINESInventors: Stéphane Raphaël Yves Richard, Jean-Luc Breining, Mathieu Pierre Cladiere, Olivier Pierre Descubes, Jerome Dinquel, Gabriel Gorka Exilard, Bertrand Guillaume Robin Pellaton, Nicolas Christophe Perra, Christophe Nicolas Henri Viguier

Publication number: 20240328617Abstract: A longitudinal-axis (X) dihydrogen injection device is configured to be mounted on an annular bottom of an annular combustion chamber of a turbomachine. The injection device includes an inner channel for dihydrogen circulation and an outer annular channel for circulation of a mixture of at least air. The inner channel and the outer annular channel are coaxial. An inner swirler is housed in the inner channel and an outer swirler is housed in the outer annular channel. A downstream end of the inner channel is arranged upstream, at a distance r, from a downstream end of the outer annular channel.

Patent number: 10166676Abstract: Some implementations are directed to methods and apparatus for determining, based on sensor data generated during physical manipulation of a robot by a user, one or more grasp parameters to associate with an object model. Some implementations are directed to methods and apparatus for determining control commands to provide to actuator(s) of a robot to attempt a grasp of an object, where those control commands are determined based on grasp parameters associated with an object model that conforms to the object. The grasp parameter(s) associated with an object model may include end effector pose(s) that each define a pose of a grasping end effector relative to the object model and/or translational force measure(s) that each indicate force applied to an object by a grasping end effector, where the force is at least partially the result of translation of an entirety of the grasping end effector.Type: GrantFiled: June 8, 2016Date of Patent: January 1, 2019Assignee: X DEVELOPMENT LLCInventors: Nicolas Henry Hudson, Crystal Chao

Patent number: 10031185Abstract: Determining a state of charge (SOC) of a rechargeable battery includes using a first process to determine a first value for the SOC of the battery and using a second process to determine a second value for the SOC of the battery and deriving the SOC as a weighted average of the first value for the SOC and the second value for the SOC. During a charging cycle of the battery an input charge of the battery is determined from an input current flowing into the battery and a charging time. During a discharging cycle an output charge of the battery is determined from an output current flowing out of the battery, a discharging time and an actual capacity of the battery is the sum of the input charge over charging cycles minus the sum of the output charge over discharging cycles.Type: GrantFiled: February 4, 2014Date of Patent: July 24, 2018Assignee: EXIDE TECHNOLOGIESInventors: Rainer Bussar, Gerd Wessels Hoogestraat, Wolfgang Rudolf Fischer, Thomas Hopper, Nicolas Henri Bernard Redon, Olaf Sielemann, Sebastian Zeh

Patent number: 9677505Abstract: An air/fuel mixer system of a combustion chamber of a gas turbine includes at least one compressed air intake swirler, the swirler having a central axis of symmetry, and a fuel injector including an injection head having an axis of symmetry. Each injector is mounted in the corresponding swirler with aid of a guide mechanism, so that the axis of symmetry of the injection head is off-center with respect to the central axis of symmetry of the swirler. The system can reduce, or even eliminate, combustion instabilities, by injecting the fuel along a particular axis which is off-center relative to the axis of the air/fuel mixer system, inducing a flow of fuel which is no longer perfectly axially symmetrical.Type: GrantFiled: June 19, 2012Date of Patent: June 13, 2017Assignee: TURBOMECAInventors: Nicolas Savary, Claude Berat, Hubert Hippolyte Vignau, Christophe Nicolas Henri Viguier
