  • Patent number: 11118048
    Abstract: Nanostructures and associated compositions, systems, and methods are provided. In some embodiments, a nanostructure may comprise polymers, intermolecular bonding groups, and a particle. The polymers may be associated with the particle and the intermolecular bonding groups may be associated with at least some of the polymers. In some embodiments, at least some of the intermolecular bonding groups may have a different chemical composition and/or chemical property than the polymers. In some embodiments, nanostructures may reversibly associate with each other via the intermolecular bonding groups to form a material. In some such cases, the intermolecular bonding groups on different nanostructures may reversibly associate with each other. In some embodiments, the nanostructures may be designed, such that the energy required to disassociate at least a portion of the nanostructures in the material is greater than the energy required to dissociate a single association between intermolecular bonding groups.

  • Publication number: 20080156243
    Abstract: A hatch installation comprises a hatch surround defining a hatch opening and a hatch door. The hatch door has a mounting end and a free end, and is pivotal between a closed position in which it abuts against the hatch surround and an open position spaced away from the hatch surround. The installation includes a cover member shaped to form a ventilation passage together with the hatch surround having one ventilation opening at the free end of the door and the other ventilation opening towards the end. The ventilation cover includes a water screen having three baffles and a sheet mesh for screening out moisture entrained with air. The ventilation cover includes a further sheet mesh water screen across the other opening. The sheet mesh acts with the hatch door to remove moisture entering through the opening.

  • Patent number: 6625000
    Abstract: Improved modular transient voltage surge suppressor apparatus are disclosed that equalize transient current sharing between multiple modules. In general, such apparatus includes first and second transient voltage surge suppression modules, each module having a non-conductive housing with a surge suppression circuit contained therein, and first and second electrically-conductive buses mechanically coupled to the non-conductive housing and electrically coupled to first and second terminals of the surge suppression circuit, respectively. A first bus coupler couples the first electrically-conductive buses of the first and second transient voltage surge suppression modules and a second bus coupler couples the second electrically-conductive buses of the first and second transient voltage surge suppression modules, whereby the surge suppression circuits in each of the first and second modules are electrically coupled in parallel.

  • Patent number: 6055147
    Abstract: An apparatus for providing independent over-current protection to a plurality of electrical devices and a transient-voltage suppression system employing the apparatus. In one embodiment, the apparatus includes a non-conductive body having a plurality of bores extending through the body from a first portion to a second portion of the body, a plurality of fusible elements corresponding to and disposed within the plurality of bores, each of the fusible elements having a first terminal proximate to the first portion of the body and a second terminal proximate to the second portion, and a common electrode coupled to the first terminal of each of the plurality of fusible elements. The common electrode is couplable to a source of electrical power and the second terminals of each of the plurality of fusible elements are couplable to an electrical device, such as a metal oxide varistor in a transient-voltage suppression system.

  • Patent number: 5319343
    Abstract: An integrated magnetic filter inductor having series and common mode windings includes a magnetic core (44) having a first leg (46), a second leg (48), and a third leg (50). The first leg (46) is connected to the second leg (48) with bridging structures (52) and (54). In a similar manner, the third leg (50) is connected to the second leg (48) with bridging structures (56) and (58). A common mode winding (64) is wound about the bridging structure (52) with a given dot orientation. A common mode winding (66) is wound about the other bridging structure (54) with the same dot polarity. Current flowing into the dot terminal of the common mode winding (64) and out of the dot terminal of the common mode winding (66) result in a net zero magnetic flux induced in the magnetic structure (44). A common mode winding (68) is wound about the bridging structure (56) with a predetermined dot polarity. A common mode winding (70) is wound about the other bridging structure (58) with the same dot polarity.
