  • Publication number: 20200227896
    Abstract: An apparatus includes a first terminal configured to be coupled to a substation around mat for a substation and a second terminal configured to be coupled to a safety around mat for a piece of electrical equipment powered by the substation. The system further includes at least one voltage-dependent resistance device, such as at least one metal oxide varistor (MOV) configured to be coupled between the first and second terminals. At least one circuit interruption device, such as a fuse and/or a disconnect switch may be coupled in series with the at least one voltage-dependent resistance device.

  • Publication number: 20070110111
    Abstract: A power system for ultraviolet lighting includes a first network transformer structured to be powered from a first medium voltage power source and to output a first low voltage output; and a second network transformer structured to be powered from a second medium voltage power source and to output a second low voltage output. A first network protector inputs the first low voltage output of the first network transformer and outputs a third output. A second network protector inputs the second low voltage output of the second network transformer and outputs a fourth output. A spot network is powered from the third output of the first network protector and from the fourth output of the second network protector. A number of sag ride thru devices include an input powered from the spot network and an output structured to power a number of ultraviolet lights.

  • Publication number: 20070097582
    Abstract: Maintenance trip functions override the normal or specified trip functions of a low voltage circuit breaker to reduce pickup currents and/or time delays to effect faster trips, which reduces arc energy produced by faults during maintenance or testing on a live circuit breaker.

  • Publication number: 20070082199
    Abstract: The present invention relates to fiber-size compositions for coating glass or other reinforcing fiber materials that are used in the manufacturing of composites. The fiber-size composition contains at least about 4% by weight of a polyvinylpyrrolidone film former, at least one lubricant and a coupling agent. The sizing composition gives the fibers desirable properties such as high strength, improved flexibility, fuzz formation resistance, and fiber smoothness and softness.

  • Publication number: 20070059506
    Abstract: Dried bundles of chopped glass fibers that may be used in mat forming applications is provided. The chopped glass fiber bundles are formed of individual glass fibers positioned in a substantial parallel orientation. The dried chopped glass fiber bundles may be prepared by applying a size composition to attenuated glass fibers, splitting the fibers to obtain a desired bundle tex, chopping the wet glass bundles to a discrete length, and drying the wet glass bundles in a dielectric oven, a Cratec® oven, or a rotating tray oven. Alternatively, the dried chopped glass bundles may be prepared by sizing attenuated glass fibers, passing the sized fibers through a heat transfer chamber where air heated by a bushing is drawn into the heat transfer chamber to dry the glass fiber bundles, splitting the dried, sized glass fiber bundles to obtain a desired bundle tex, and chopping the dried bundles of glass fibers.

  • Patent number: 6311723
    Abstract: A fluid flow control valve (10) has a piston (43) in a first chamber (45), urged by a spring (46) to close fluid passages (36) interconnecting the first chamber (45) to a second chamber (51). A fluid level sensor (20) in a container (100) allows fluid to be bled from a downstream side of the first chamber (45), via a bleed passage (45), to enable the piston (43) to move to open the fluid passages (36). When the fluid sensor (20) detects that the fluid level (101) in the container (100) has reached a preset level, the fluid level sensor (20) shuts off flow through the bleed passage (45) and the equalization of the fluid pressure on both sides of the piston (43) in the first chamber (45) enables the spring (46) to move the piston (43) to close the fluid passages (36), shutting off fluid flow through the valve (40).

  • Patent number: 6027680
    Abstract: A method and apparatus is disclosed for the in-line pre-impregnation of glass or synthetic fibers with a non-aqueous chemical treatment. The apparatus includes a first applicator for applying a curable, non-aqueous chemical treatment agent and a second applicator for applying a curing agent for the chemical treatment agent. The fibers are passed over the first and second applicators which are arranged either in parallel or in series, and are then joined by a gathering device to initiate curing of the chemical treatment agent on the fibers. In an alternative embodiment, the apparatus includes a spray gun in which a mixture of the non-aqueous chemical treatment agent and curing agent are sprayed onto an applicator roll in contact with the fibers.
