Abstract: A method and device for optimizing tests of systems, in particular of an aircraft, including a first display module displaying a list of tests that can be executed by systems, a selection module allowing an operator to select a set of tests to be executed and communicate it to an optimization module which determines a sequence of tests representing an optimized execution of the set of tests to be executed, the sequence of tests being displayed by a second display module for an operator, a decision module generating either a first signal if the operator validates the sequence of tests, or a second signal if the operator cancels the sequence of tests, and a control module which, if the first signal is generated, commands the execution of the sequence of tests by each of the systems, and generates results of the execution thereof.

Abstract: A linear electrodynamic-type motor, for compressing a fluid circulating in a cryocooler notably using a Stirling cycle, includes a translationally movable induction coil; a power-supply circuit adapted to deliver, to at least one induction coil, an AC power-supply current; a movable mass adopting a translational movement; an induction coil arranged so as to move a respective movable mass between a first position and a second position where the movable mass can compress the fluid; and a secondary circuit arranged to connect the terminals of at least one induction coil in short-circuit. The secondary circuit comprises a compensation component for producing a phase shift between the power-supply voltage and the power-supply current, so as to reduce the phase difference that the inductance of the induction coil produces.

Abstract: At least part of an electrostatic spraying installation for spraying an electrically conductive liquid product such as a coating product is grounded. The installation includes at least one intermediate storage tank that is electrically insulated from ground and at least one electrostatic sprayer device that is supplied from this intermediate storage tank. The electrostatic sprayer device is connected to a variable or switchable high-tension voltage source. The installation includes at least one electrical insulation device which incorporates a section of insulative conduit and a liquid inlet and a liquid outlet at respective ends of this conduit section. A piston movable in the conduit section scrapes its inside wall clean.

Abstract: A device for connecting two conduit parts, in particular two parts of a pollutant fluid circuit, comprises a first connector part enclosing a first valve member elastically urged towards a first valve seat to isolate a fluid outlet. A second connector part comprises a tubular element defining an inlet conduit and enclosing a second valve member elastically urged towards a second valve seat to isolate a fluid inlet. A system is provided for cleaning contacting surfaces of the two connector parts and in particular those of the two valve members. The valve members have respective complementary shape mutually contacting surfaces and are adapted to be movable conjointly while remaining in contact so as to enable the fluid to pass.
