Patent number: 11738521Abstract: A manufacturing process of a fibrous preform for a composite material includes creating a fibrous texture by three-dimensional or multilayer weaving between a plurality of weft layers and warp layers, the fibrous texture including an extra-thick portion having a sacrificial portion and a useful portion adjacent to the sacrificial portion in the warp direction, the sacrificial portion, placing the fibrous texture in a forming toolset, shaping the fibrous texture so as to obtain a fibrous preform having a sacrificial portion and an adjacent useful portion, removing the sacrificial portion from the fibrous preform. When weaving the fibrous blank, one or more expansion elements are inserted into the weft layers located at the core of the sacrificial portion of the fibrous texture. Each expansion element has a cross-section greater than the cross-section or count of the weft threads or strands present in the useful portion.Type: GrantFiled: July 1, 2020Date of Patent: August 29, 2023Assignee: SAFRAN CERAMICSInventors: Thierry Guy Xavier Tesson, Marie Lefebvre, David Mathieu Paul Marsal

Patent number: 6003910Abstract: Lock comprising a rotary latch and a pawl for retaining the latch; external opening control rod and internal opening control rod for acting on the pawl by way of an intermediate lever and an electric drive. The intermediate lever has one end connected to the pawl. The lever being articulated in such a way as to be able to pivot at least about two different axes forming an angle between them. A pivoting of the lever about a first direction permits the locking function to be performed, a pivoting of the lever about the second direction permits the child safety function to be performed, and a combined pivoting of the lever about the first and second directions permits the double-locking function to be performed, so that the electric drive has only to control two movements in order to execute the three functions: locking, child safety and double-locking.Type: GrantFiled: September 4, 1998Date of Patent: December 21, 1999Assignee: Valeo Securite HabitacleInventors: Patrick Dupont, Jean-Marie Lefebvre, Jean-Philippe Hochart
