Patent number: 11370046Abstract: A device for machining a part by electrical discharge machining using an electrode wire. The device includes equipment for holding the electrode wire taut and driving the wire to translate longitudinally, in proximity to the part to be machined, in a sparking zone. The device further includes equipment for making a stream of dielectric liquid flow through the sparking zone between the electrode wire and the part to be machined. An electrical power source generates electrical pulses that cause sparks in the sparking zone between the electrode wire and the part to be machined. The quantity of gas bubbles present in the sparking zone is measured, and a signal is produced, representative of the quantity of bubbles, the signal being delivered to a controller. The controller modifies machining parameters so as to maintain the value of the signal within a suitable range.Type: GrantFiled: July 18, 2019Date of Patent: June 28, 2022Assignee: THERMOCOMPACTInventors: Michel Ly, Gérald Sanchez

Patent number: 8871308Abstract: A method of coating ceramic material fibers in metal using a liquid technique and a device implementing the method. The method maintains a charge of molten metal in levitation in a substantially spherical shape inside a crucible and causes a tensioned ceramic material fiber to travel at a predetermined speed between a bottom pulley and a top pulley disposed on either side of the crucible such that a portion of fiber is immersed in the charge to be covered in a metal coating. During coating, the portion of fiber that is immersed in the charge is shifted as a function of the remaining volume of the charge such that the instantaneous height of fiber that is immersed in the charge remains substantially constant throughout the coating operation.Type: GrantFiled: April 20, 2010Date of Patent: October 28, 2014Assignee: SnecmaInventors: Jean-Michel Patrick Maurice Franchet, Gilles Charles Casimir Klein, Gerald Sanchez
