  • Patent number: 5614881
    Abstract: A current limiting device utilizing an electrically conductive composite material and an inhomogeneous distribution of resistance structure is disclosed. The inhomogeneous distribution is typically chosen so that at least one selected thin layer of the current limiting device has much higher resistance than the rest of the current limiting device. In the actual device, pressure is typically exerted on the composite material in a direction normal to the selected thin layer. During a short-circuit, it is believed that adiabatic resistive heating of this selected thin layer is followed by rapid thermal expansion which leads to either a partial or complete physical separation of the current limiting device at the selected thin layer which produces a higher over-all device resistance to electric current flow. Thus the current limiting device limits the flow of current through the short-circuited current path.

  • Patent number: 5455105
    Abstract: A meshed for producing an abrasion-resistant, ultraviolet radiation cured coating on a surface of a polymeric substrate is disclosed, as well as the article produced from the method. The uncured coating material which is substantially free of non-reactive volatile components is (i) applied to the substrate (ii) heated along with the substrate to a temperature sufficient to drive a portion of the coating material into a region beneath the surface of the substrate, (iii) and cured onto the substrate by exposing the coating material under anaerobic conditions to sufficient ultraviolet radiation to cure the coating material. Heating of the solvent-free coating prior to ultraviolet radiation cure and while in contact with the substrate results in improved adhesion of the coating to the substrate.
