Abstract: A pneumatic tire has a tread comprising two wide grooves of circumferential orientation and rows of wide grooves of transverse orientation defining circumferential rows of elements in relief. The tread is characterized by the following combination:A. A middle row and two side rows of elements in relief are formed, separated in each row by grooves of transverse orientation discharging alternately, in the case of the middle row, into the wide grooves of circumferential orientation and, in the case of the side rows, into the adjacent wide groove of circumferential orientation and into the adjacent edge of the tread.B. The grooves of transverse orientation of each row of elements in relief are connected in pairs by grooves of reduced width and at most the same depth as the depth of the longitudinal and transverse grooves.C. The sum of the lengths, projected on a meridian section, of the transversely oriented grooves connected in pairs is between 0.75 and 1.5 times the width of the tread.

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.
