    Abstract: A combiner for optical beams includes a substrate overlaid by a multi-layer dielectric film stack. The substrate is a clear material and the dielectric film stack is a series of alternating layer of high and low refractive index. This gives the combiner relatively high reflectivity across UV wavelengths and relatively high transmissivity in the visible and longer wavelengths and allows visible light to pass through the combiner while UV light is reflected. At the same time dielectric film stack has minimal absorption and scatter. This means that the intensity of visible light maintains at least 90% of its intensity as it passes through combiner and UV light retains at least 90% of its intensity as it is reflected by combiner.

    Abstract: 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.

    Abstract: 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.
