Abstract: A YSZ-type ceramic layer is deposited on a tie sublayer by thermal spraying using a plasma arc torch, said tie sublayer being itself deposited on the part to be protected. A sintering post treatment is carried out by means of a sweep of the ceramic layer by the beam of the plasma arc torch, the temperature at the point of impact of the beam at the surface of the ceramic layer (C) being, during this sweep, between 1300° C. and 1700° C.

Abstract: According to a first aspect, the invention relates to a thermoelectric module (10) that comprises a thermoelectric layer (15) comprising one p-type (7p) and one n-type (7n) portions presenting together an upper and a lower main surfaces (11,12). The thermoelectric module (10) further comprises a first and a second thermal resistor elements (1r, 2r), and a first thermal bridge element (3c), between and adjacent to the first and second thermal resistor elements (1r, 2r). The first and second thermal resistor elements (1r, 2r) and the first thermal bridge element (3c) cover the whole lower main surface (12). The p-type (7p) and the n-type (7n) portions are adjacent and directly coupled by an interface (7i). The first thermal bridge element (3c) spans at least over the orthogonal projection of the interface (7i) on the lower main surface (12).

Abstract: A reservoir for a liquid circuit has a partition dividing it into an upper chamber and a bottom chamber from which liquid is drawn via an outlet conduit. An inlet conduit for returning liquid to the reservoir opens into a deaerator which is mounted on the partition so that the liquid is returned into the bottom chamber and the separated gas is discharged through a degassing orifice which opens into the upper chamber. The deaerator is provided with a valve which closes the degassing orifice when the reservoir is inverted or subjected or negative gravity, thus ensuring the continuing supply of liquid to the circuit under all operating conditions.
