Abstract: An apparatus for installing cables in overhead transmission and distribution systems and a corresponding method of use are disclosed herein. The apparatus described herein may comprise a dual messenger rolling cable spacer used to install cables in overhead transmission and distribution systems. In various embodiments, the method of using the dual messenger rolling cable spacer may include installing a carrier messenger wire across a span between utility structures. One or more rolling spacers may then be hung from the carrier messenger wire via a roller such that the roller is in contact with the carrier messenger wire. A set of cables and a circuit messenger wire may be affixed to the one or more rolling spacers. The circuit messenger wire may then be pulled across the span causing the one or more rolling spacers to roll along the carrier messenger wire, thereby pulling the set of cables across the span.

Abstract: A temperature control system for electric range surface heating elements including an infinite switch electrically coupled to a surface heating element and a second switch, which selectively couples 120 VAC or 240 VAC power across the infinite switch and heating element. Alternatively, the second switch selectively couples either the infinite switch or an electronic controller to a surface heating element, wherein the electronic controller has timing circuits for cycling power supplied to the surface heating element according to a preset timing scheme within the timing circuits.

Abstract: The invention disclosed is a foamable fluid explosive composition which is capable of being projected over suspect terrain to form a continuous blanket of explosive foam which may be detonated by conventional means. The novel fluid explosive composition comprises______________________________________ a suitable liquid foamable explosive 57-98%/w a suitable liquid emulsifier 2-6%/w a suitable stabilizer 0-5%/w a suitable thickener 0-7%/w a sensitizer 0-5%/w energy enhancer/inert metals 0-20%/w ______________________________________wherein the amounts of ingredients are expressed as percent by weight of the composition, excepting the sensitizer which is expressed as percent by weight of the explosive. The same fluid explosive composition is adapted for aerosol delivery by including a suitable compressed liquified gas as propellant.

Abstract: A detachable immersible support for supporting articles in a swimming pool comprising a mooring bracket, a U-shaped frame member, an article support, and a frame member spacer, wherein the mooring bracket is comprised of two substantially horizontal oppositely disposed ends of a vertical central portion, one end is adapted to be fastened to the coping on the pool or the ground beside the coping, the vertical portion is adapted to be spaced a short distance inside the wall of the pool, the second horizontal end extends outwardly from the vertical member, the U-shaped frame member is comprised of a down leg, a horizontal leg and an up leg, the upper end of the down leg is fastened to the mooring bracket and is adapted to be suspended substantially parallel to and spaced from the pool wall, the horizontal leg of the U-shaped frame member is arranged at substantially 90 degrees relative to the down leg, the up leg of the U-shaped frame member is arranged at substantially 90 degrees relative to the horizontal leg

Abstract: A device for damping vibration, such as aeolian, of a suspended conductor. The device comprises at least one helical spring, at least a portion of the turns of which are close wound, and means for attaching the spring to a conductor in spaced relation thereto. At least one inertial weight is mounted on or attached to the spring so that the weight can be resiliently suspended from the conductor by the spring and attaching means. The inertial weight is effective to relatively translate and thereby provide sliding friction between the close wound turns of the spring in a direction perpendicular to the axis of the spring when an associated conductor undergoes vibration above a given magnitude, and to bend the helical spring such that adjacent close wound turns of the spring separate from and impact against each other, the sliding friction and impacts between the turns of the spring being effective to dissipate the energy of the vibration of the conductor in the form of heat.
