Latest Patents

Christian Dorval's most recent patents showcase his expertise in mechanical connections within actuator systems. His first patent details a mechanical connection between a primary nut and a secondary nut. This innovative assembly consists of both a first and second nut designed to work in conjunction with a screw, particularly within the context of an adjustable tailplane actuator for aircraft. Notably, the design integrates means for fusible driving between the two nuts, incorporating adjustable spacing mechanisms that establish a wedge effect, enhancing performance and reliability.

Another noteworthy invention by Dorval involves the use of an electrified pin for detecting load transfer in a screw actuator. This actuator, which operates by actuating a moving member through the engagement of screws and multiple nuts, includes a pin that allows electrical connectivity. A force-transmitting element positioned between the screw and the moving member ensures that any unexpected shifts in the force-transmitting element trigger a shear event, breaking the pin and thus severing the electrical link. This clever design adds an extra layer of safety and precision in actuator functionality.
