Abstract: A lubrication reservoir for a turbine engine for an aircraft or self-propelled flying machine, comprising a suction strainer in a lower part of the chamber, and at least one degassing device and at least one vent in an upper part. The reservoir is wherein, in order to make it possible to supply the strainer and prohibit lubricant from intruding into the at least one vent, it includes at least one first partition that separates the lower part from the upper part and is pierced with calibrated holes, two vents arranged on either side of a vertical median plane of the chamber and two vent ducts which extend into the upper part below the degassing device, each duct comprising a bend and having the bend located on the other side of the median plane with respect to the inlet thereof.

Abstract: A material with high mechanical strength and a density close to 1 is obtained by:(a) dispersing on weight basis 10-15% of a melamine-formol resin, 10-50% of hollow microspheres, and optionally up to 60% of light aggregates, in water;(b) mixing the resultant dispersion in the presence of a cross-linking catalyst, e.g., ammonium chloride, for the melamine-formol resin, until a fluid paste is obtained; and(c) allowing said fluid paste to harden into the desired material.
