  • 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: 11021702
    Abstract: The present invention provides a method of preparing a nucleic acid library, which includes providing a one or more nucleic acid samples, and a one or more of samples of solid state capture material; contacting each nucleic acid sample with a sample of capture material to provide captured nucleic acid samples; and pooling the captured nucleic acid samples to provide the nucleic acid library. The method is particularly suitable for preparing nucleic acids for sequencing, especially next generation sequencing and related methods such as genotyping-by-sequencing.
