Abstract: The present invention relates to a test system (1) for at least one aircraft navigation instrument (3), said system comprising: a test device (5) capable of being connected to at least one sensor on which the navigation instrument relies to provide a value, said test device being configured to test said sensor by changing its state; a database comprising at least one predetermined value corresponding to a value to be provided by said navigation instrument when said test device changes the state of said at least one sensor associated with said navigation instrument.

Abstract: The invention relates to an installation (1) for detecting and locating a leak in at least one fluid transport circuit (Ps, Pt), notably an anemometer circuit of an aircraft, having a leak test apparatus (10) including means (12) for detecting a leak in the said at least one fluid transport circuit (Ps, Pt). In one example, the means for locating a leak includes injecting means (Pp, 14, Ev2) of a trace gas under pressure into the said at least one fluid transport circuit (Ps, Pt), which means are situated in the said leak test apparatus (10), and a trace-gas detection probe (30) intended to be moved along the said at least one fluid transport circuit (Ps, Pt) on the outside thereof, in order to locate the leak.

Abstract: Systems and methods for battery testing are described. Some of the methods for battery testing include applying a first load impedance to a battery, applying a second load impedance to a reference voltage source, measuring a voltage between a positive terminal of the battery and a positive terminal of the reference voltage source, wherein a negative terminal of the battery is connected via a conductor to a negative terminal of the reference voltage source, and determining a condition of the battery based on the measured voltage.

Abstract: The invention relates to an actuating device for a device for dispensing a fluid product, the dispensing device including a receptacle having an opening at the upper end thereof, a dispensing member (1) being mounted in said opening, the dispensing member (1) including a cylindrical push member (3) which has a vertical axis (3a), and the upper end of which extends vertically upward. Exerting pressure on the upper end of the push member (3) triggers the egress of the fluid product from the container via the dispensing member (1).

Abstract: A fishing reel has a fixed spool and a rotary line pick up. The spool comprises a peripheral groove for line retrieval limited by a front flange and a rear flange. The front flange comprises, for example, three peripheral areas with a progressively smaller radius with a dimension of the radius that is smaller than the radius in the adjacent peripheral areas that separate them. Therefore we reduce the friction of the fishing line on the front flange of the spool during a casting operation.

Abstract: The reel according to the invention comprises a spool support shaft that is held in a reel housing by its rear section and supports a front hub that comprises a front cylindrical coaxial barrel connected by means of a shoulder to a coaxial rear skirt. A line supply extends onto the front cylindrical coaxial barrel of the front hub and locks by means of an axial hole. The line supply comprises a solid front wall, blocking the axial hole toward the front.

Abstract: A cylindrical pump body is axially disposed in a container and has an annular shoulder sealingly abutting an outer end of the container neck opening. The wall of the pump body is press fit against the interior wall of the container neck. A cylindrical sleeve is telescopingly press fit within an outer end portion of the pump body and has an annular collar sealingly abutting the pump body shoulder. The press fit between these components as well as their abutting annular sections ensures securement of the components within the container as well as the sealing of container contents therein without the use of threaded closures of gaskets.
