    • A process for making a high-strength spun yarn begins by feeding one or more tows of substantially uncrimped continuous filaments of high-modulus material having a tensile modulus exceeding about 20×106 psi through a high-speed stretch-breaking apparatus operating at low total draft ratio (preferably about 2.0) to break the filaments into high-modulus staple fibers having an average length in the range of about 5 to 6 inches. The tows advantageously are heavy, for example, having a denier of about 25,000 to about 500,000. Following the stretch-breaking step, the staple fibers are collected in sliver cans, and the staple fibers are advanced from the sliver cans to a spinning machine, where the fibers are spun into yarn. An important aspect of the invention is that no intermediate processes are performed between the stretch-breaking and spinning processes, which minimizes disruption of the alignment of and damage to the staple fibers.
    • 用于制造高强度纺织纱线的方法开始于将具有超过约20×10 -6 psi的拉伸模量的一个或多个基本上未卷曲的高模量材料的连续长丝的丝束通过高速拉伸 - 破裂装置以较低的总通风比(优选约2.0)操作,以将长丝断裂成具有在约5至6英寸范围内的平均长度的高模量短纤维。 丝束有利地是重的,例如,具有约25,000至约500,000的旦尼尔。 在拉伸断裂步骤之后,将短纤维收集在纱条中,并且将短纤维从棉条提前到纺丝机,其中纤维被纺丝成纱线。 本发明的一个重要方面是在拉伸断裂和纺丝过程之间不进行中间工艺,这使得短纤维的对准和损坏的破坏最小化。

    • A device includes a housing that has a plurality of monolithically formed walls, wherein selected walls are provided with inlet and outlet ports respectively. The housing includes a coupling in fluid communication with the inlet and outlet ports, a mechanism for detecting a fluctuation in water pressure, and a mechanism for selectively prohibiting water flow. The prohibiting mechanism cooperates with the detecting mechanism. The housing also includes a mechanism for providing an audible notification when the water supply is toggled between interrupted and reinstated modes and a mechanism for manually controlling the prohibiting mechanism. The manually controlling mechanism is electrically coupled to the prohibiting mechanism. An internal power supply source supplies power to the detecting mechanism, the prohibiting mechanism, and the manually controlling mechanism. A diode is attached to the housing and is illuminable when the power supply source reaches a minimum threshold level.
