  • Patent number: 5106394
    Abstract: An optical glass fiber polishing apparatus and method utilizing a slurry prised of water, CeO, glycerin and where needed, a base such as NaOh, to realize transmission loss in the fiber as it is polished towards the fiber core. The intensity of light introduced at one end of the fiber is measured at the opposite end, continuously and without interruption of the polishing, to determine polishing progress through the cladding towards the core.

  • Patent number: 4988554
    Abstract: A coated abrasive article comprising a backing bearing on one major surface thereof a layer of abrasive grains overcoated with a loading resistant coating and on the other major surface thereof a layer of pressure-sensitive adhesive. The loading resistant coating comprises a lithium salt of a fatty acid. It may also contain additives selected from the group consisting of surfactants, wetting agents, binders, anti-foaming agents, fillers, plasticizers, and mixtures thereof. The use of a lithium salt of a fatty acid significantly reduces the amount of transfer between the loading resistant coating of a first coated abrasive article and the pressure-sensitive adhesive layer of a second coated abrasive article disposed within a package.
