Abstract: An axially hyperstatic system softener for a transmission comprising a static component and a rotatable component mounted to each other by a double ball bearing having an outer race and an inner race includes first and second biasing elements in a rigid sleeve with the outer race disposed between the first and second biasing elements. The rotatable component includes two shafts splined together with the static component mounted to one of the shafts by the bearing double ball bearing. A shim between one of the biasing elements and the sleeve enables tuning the softener.

Abstract: A fan blade support assembly for an aircraft is generally disclosed. The fan blade support assembly includes a fan assembly having a plurality of fan blades, a power shaft extending between the fan assembly and an engine of the aircraft, and a housing assembly positioned around the power shaft. The housing assembly includes a convergent housing and a sealing shroud. The convergent housing includes a cap, a base, and a middle portion extending therebetween. The base defines a first diameter, and the cap defines a second diameter less than the first diameter. The sealing shroud is positioned between the convergent housing and the power shaft. A gap is defined between the sealing shroud and the power shaft.

Abstract: A linear lighting apparatus, comprises a plurality of lighting sources aligned along a main axis of the apparatus a cylindrical lens with its axis parallel to the main axis of the apparatus, said cylindrical lens being suitable to receive most of the light emission generated by the lighting sources and to emit a substantially collimated light beam, and a reflector suitable to reflect at least a portion of the light emission not refracted by the cylindrical lens.

Abstract: A lighting device, in particular suitable for being embedded in the ground, comprising an external appliance body, of a substantially cylindrical shape, comprising a bottom wall and a side wall which extends from said bottom wall. A lighting source attached to said bottom wall of the external appliance body and suitable to emit a beam of light with a main axis (X), towards a lens suitable to focus said beam of light. Lateral translation means are also provided for suitable to cause a translation of the lens on a lens plane orthogonal to said main axis so as to offset the center of the lens from said main axis, and rotation means suitable to cause a rotation of the offset lens on said lens plane around said main axis.

Abstract: A lamp having a base housing with a member for connection to a lamp-holder, and a light source extending generally axially from the housing. The lamp includes a device connected to the housing suitable for screening the dispersion of the light radiation in undesired directions. Such device preferably comprises a hood with a generally cylindrical grid arranged coaxially to the housing and enclosing the light source. Desireably, the grid is formed from a plurality of substantially frusto-conical rings axially superimposed, joined and regularly spaced by a plurality of axial ribs.
