    摘要： A polymeric composition in pellet form comprising a tacky hot melt composition, comprising a) from about 5% by weight to about 90% by weight of a thermoplastic polymer, b) from about 0% by weight to about 65% by weight of a tackifying resin, c) from about 0% to about 50% by weight of a plasticizer, d) up to about 2% by weight of an antioxidant, and a pelletizing aid, wherein the tacky hot melt composition has some minimum amount of tackifier or plasticizer and is a pressure sensitive adhesive having a storage modulus, G', at about 25.degree. C., of less than about 5.times.10.sup.6 dynes/cm.sup.2, and each pellet has a substantially tack-free surface.This invention further discloses a polymeric composition in pellet form suitable for molding articles. The composition comprises a tacky hot melt composition comprising at least one high molecular weight triblock copolymer of the general configuration A-B-A and a plasticizer and a pelletizing aid. The pelletizing aid substantially surrounds the tacky composition such that the molded articles are substantially free from surface tack.A method of forming the pellets is also disclosed.

    摘要： Each bomblet within a cluster bomb is provided with an individually programmable detonation time delay, such that the bomblets can be programmed to detonate at desired intervals over a relatively long period of time. Program signals are transmitted to a number of bomblets at the same time from a wire that runs through openings in the bomblets, but is not mechanically attached to the bomblets. The wire is attached to the bomb canister at selected points and is severed inbetween the connection points when the canister is opened, thus permitting the wire sections to be pulled away without disrupting the bomblets' dispersion pattern. A shaped charge running along at least one of the canister sections is used to sever the wire. The shaped charge is arranged to direct its explosive force toward the adjacent canister section and generally away from the bomblets, and generally comprises a chevron-shaped casing filled with an explosive.

    摘要翻译： 集束炸弹内的每个炸弹被提供有单独可编程的爆炸时间延迟，使得该炸弹可以被编程为在相对长的时间段内以期望的间隔引爆。 程序信号同时从一个穿过炸弹中的开口的电线传输到多个炸弹，但不机械地连接到炸弹。 导线在选定的点附接到炸弹罐，并且当罐被打开时在连接点之间切断，从而允许将线段拉开而不破坏炸弹的分散模式。 使用沿着至少一个罐部分延伸的成形的电荷来切断电线。 成形装置被布置成将其爆炸力指向相邻的罐部分并且通常远离炸药，并且通常包括填充有炸药的人字形状的壳体。
