    Abstract: The novel compound, tetranitroglycoluril, is described having a stability under vacuum of 6 cm.sup.3 /g/100 hours at 110.degree. C. The compound exhibits a rate of detonation at least equal to 9,073 meters per second under a density charge of 1.94, has a decomposition temperature of about 200.degree. C. and is stable at a temperature of up to 100.degree. C. at normal pressure. It may be dried at 65.degree. C. The brisance value by the Friedrich's formula is 159.7.times.10.sup.6. The rate of detonation and brisance value are superior to octogen.

    Abstract: The present invention relates to nitrocellulose single-base propellent powders which exhibit good resistance to aging and to moisture. The powders according to the invention characteristically contain zinc carbonate whose particle size distribution is between 2 and 50 micrometers as an additive. The zinc carbonate is incorporated in the powder during the blending. The powders according to the invention find their preferred applications as propellent powders for ammunition intended for warships or for aircraft or as powders intended for gas generators for pyrotechnic devices.

    Abstract: Support ring assembly for tires comprising a rigid ring of I-shaped cross-section having an outer diameter less than the inner diameter of the tire tread when the tire is under load and having an inner diameter greater than the outer diameter of the cylindrical wheel rim is improved due to the fact that the assembly further comprises at least one solid annular part of elastic material which is mountable between the rim and the rigid ring, the annular part having an outer diameter substantially equal to the inner diameter of the rigid ring and having an inner diameter and width such that after the tire has been mounted on the rim, the fastening of the assembly on the rim is assured by compression of the elastic material of the annular part.
