Abstract: Magnetic cooling device comprising a magnetocaloric element, the magnetocaloric element comprising a paramagnetic garnet ceramic. The density of the paramagnetic garnet ceramic is preferably greater than or equal to 90%. The garnet ceramic is preferably a gadolinium gallium garnet ceramic or an ytterbium gallium garnet ceramic.

Abstract: Manufacturing method by addition for at least one part of a piece of aeronautic equipment intended to equip an aircraft, the equipment piece including at least one part intended to be arranged at a skin of the aircraft and heating elements for that part, which include a thermodynamic loop including a closed circuit at least partially integrated, in which a heat transfer fluid circulates, the closed circuit including an evaporator and a zone in which condensation of the heat transfer fluid can occur in the appendage to heat it, outside the evaporator, the circuit being formed by a tubular channel with an empty section at least partially integral with the equipment piece, at least the part of the equipment piece arranged outside the aircraft is made by additive manufacturing and includes a base for fastening on the skin of the aircraft from which support elements for a Pitot tube extend.

Abstract: A cooling device comprises a cooling tube containing a working gas, a pressure oscillator connected to a first end of the cooling tube to generate a pressure oscillation and displacement of the working gas, and means for phase shifting the pressure oscillation relative to displacement of the working gas, connected to a second end of the cooling tube. The device further comprises a first sealed pressure transmission element to separate the working gas from a fluid contained in the phase shifting means. The fluid and the working gas are of different natures.

Abstract: The method and apparatus for delivering generally flat articles one by one make use of first and second conveyors. The first conveyor has a top article-supporting surface operated at a first linear speed in a forward direction. In operation, a stack of generally flat articles lies on one side on this top article-supporting surface longitudinally of the first conveyor. The second conveyor is installed in series with the first conveyor, operates at a second linear speed higher than the first linear speed in the forward direction, slopes upwardly in the forward direction, and includes a plurality of generally parallel, rotative longitudinal screws having respective threads structured to engage a lower edge of the generally flat articles. According to the method, the generally flat articles are jogged and thereby separated from each other through slipping of the lower edges of these articles on the successive ridges and grooves of the threads of the rotative longitudinal screws.
