A lighting fixture for an enclosed space having a humid environment is provided, including a tubular profiled section made of synthetic material having a rectilinear cross section arid a regular profile, and a support for electrical components including a metal blade with elastic properties having a width generally corresponding to an interior width of the profiled section including a base for resting against a face of the profiled section, two end returns disposed generally perpendicular to the base and having a height slightly smaller than that of the profiled section, two facing flanges extend respectively from the two end returns including ends for anchoring in an upper wall of the profiled section, and two end plugs for closing the ends of the profiled section, each plug including a part being pushed into the profiled section including an O-ring.

Illuminating fixture for enclosed space containing a humid environment

A filter external to a tank, including a vessel, a lid for closing the vessel, a basket disposed in the vessel for housing filtering components, a top wall bearing sealingly in a central part of the lid allowing communication with the central part, a water-circulating pump disposed in the central part, and means for automatically removing air from a water delivery side, wherein the water is conveyed through the lid by first piping passing through the lid, the water moving down into the vessel on an outside of the basket, entering the basket via a bottom of the basket, passing upward through the basket over the filtering components and leaving the basket at a top of the basket in the central part to be sucked up by the pump and delivered to second piping passing through the lid toward a pipe delivering to the tank.

External tank filter, in particular for an aquarium

A filter external to a tank including a vessel, a lid for closing the vessel, a removable connector including means of fixing the connector to the lid, a pipe for conveying water from the tank, a pipe for returning water to the tank, and couplings for connecting the two pipes to the connector, each coupling being equipped with a valve which selectively allows or prevents the passage of water, the connocter including a single means for allowing simultaneous actuations of the valves and actuation of the means of fixing the connector to the lid.

The device comprises a body having a longitudinal central bore for passing a probe therethrough intended to penetrate into the hole to be tested. The probe is fixed to the body by a matching socket having a locking screw. A ring is slidably mounted on the body, and secured against rotation by a screw engaged in a longitudinal groove of the body. A spring pushes the ring back with respect to the body, the movement being limited by a stop. The front part of the ring receives an insert stop coming to bear against the outer face of the workpiece to be tested. At the end of penetration of the probe into the hole, the rear part of the ring comes opposite an annular mark formed in the body.
