  • Patent number: 11952963
    Abstract: A thrust reverser for a turbojet aircraft nacelle includes a fixed structure, a movable structure and an actuator. The actuator extends along a main axis and is connected by a first connection to the fixed structure and by a second connection to the movable structure for the deployment of the movable structure between a direct jet position and a reverse jet position. The actuator is also connected to the fixed structure by a third connection arranged longitudinally between the first connection and the second connection. An axis of the third connection is radially eccentric from the main axis and the third connection allows a predetermined displacement of the actuator with respect to the fixed structure.

  • Patent number: 9771485
    Abstract: A metallic nanoparticle dispersion includes a dispersion medium characterized in that the dispersion medium includes a solvent according to Formula I, wherein R1 and R2 represent an optionally substituted alkyl group, and R1 and R2 may form a ring. When using a solvent according to Formula I as a dispersion medium, no polymeric dispersants are necessary to obtain stable metallic nanoparticle dispersions.

  • Patent number: 9243159
    Abstract: A dispersion includes metallic, metal oxide, or metal precursor nanoparticles; a thermally cleavable polymeric dispersant; an optional dispersion medium; and a thermally cleavable agent. Pastes, coated layers, and patterns may contain the dispersion. A method for producing the specific thermally cleavable dispersant and for producing the metallic nanoparticle dispersions. The dispersions allow the reduction or avoidance of organic residue in coated layers and patterns on substrates, the use substrates of low thermal resistance, and faster processing times.
