    • The present invention relates to the field of propellent charges for small and medium calibre arms.The invention relates to a process for the manufacture of fragmentable propellent charges, which consists in a first stage in coating powder particles with a mixture of dinitropolystyrene and of a compound of the polyvinyl nitrate and/or polyvinyl acetate type and, in a second stage, in compressing at between 100.degree. C. and 140.degree. C. the powder particles thus obtained.The invention also relates to the fragmentable charges obtained by the process and to the coated particulate powders obtained at the end of the first stage of the process.The fragmentable charges according to the invention exhibit a temperature behaviour which is superior to that of traditional fragmentable charges and are suitable for cartridgeless ammunition intended for arms with a high rate of fire.
    • 本发明涉及中小口径武器的推进装置领域。 本发明涉及一种用于制造可破碎的推进剂的方法,该方法包括在用二硝基聚苯乙烯和聚乙酸亚乙酯和/或聚乙酸乙烯酯类型的混合物涂覆粉末颗粒的第一阶段中,在第二阶段, 在100℃和140℃之间压缩由此获得的粉末颗粒。 本发明还涉及通过该方法获得的可裂解电荷以及在该方法的第一阶段结束时获得的涂覆颗粒粉末。 根据本发明的可破碎的电荷表现出比传统的可分散电荷优越的温度行为,并且适合于用于具有高火焰量的臂的无卡通弹药。

    • 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.

    • The reinforcement of a pneumatic tire comprises, proceeding in a direction from the inside towards the outside of the tire, a carcass reinforcement continuous from bead to bead and three superimposed plies of cords limited to the region of the tread. In the sidewalls of the tire, the cords of the carcass reinforcement form a substantially constant angle with the circumferential direction of the tire of between 70.degree. and 90.degree.. In the tread region of the tire, the cords of the carcass reinforcement form an angle with the circumferential direction of the tire which is smaller than the angle made by those cords in the sidewalls. The cords of the three tread plies form acute angles .alpha., .beta., and .gamma., respectively, with the circumferential direction, and the cord angle .alpha. of the one of the three tread plies nearest the carcass reinforcement and the cord angles .beta. and .gamma. of the second and third of the three plies, respectively, are related as set forth below in mathematical expressions.
    • 充气轮胎的加固包括从轮胎的内侧向外侧方向延伸的胎圈增强件,其从胎圈到胎圈的连续部分,以及三个重叠的帘线帘布层限定在胎面区域。 在轮胎的侧壁中,胎体加强筋的帘线与轮胎的圆周方向形成大致恒定的角度在70°和90°之间。 在轮胎的胎面区域中,胎体加强筋的帘线与轮胎的圆周方向形成一个角度,该角度小于由侧壁中的这些帘线产生的角度。 三个胎面帘布层的帘线分别与圆周方向形成锐角α,β和γ,并且三个胎面帘布层中最靠近胎体增强件的帘线角α和帘线角度β和γ 三层的第二和第三层分别与数学表达式相关。
