  • Publication number: 20040212985
    Abstract: The present invention is an electro luminescent and or magnifying bookmark. The illumination of the bookmark is achieved through electro luminescent technology. All of the electronic components of the EL lamp make up the entire bulk of the bookmark. The EL lamp can be turned off or on depending on user's need to illuminate text. For the purpose of description, the magnification will always be thought of as external to the bookmark, such that it is a peripheral and optional application. The magnification is achieved by a lens comprising a flat rectangular or other suitable shape of transparent plastic sheet material having fresnel lens contours molded in its upper surface producing desired magnification. The magnification lens can be added or removed from the bookmark at the user's discretion. Whatever shape and dimension the El bookmark takes, the magnifying lens, to be cooperative must follow in shape and dimension.

  • Patent number: 4903476
    Abstract: An igniter for a combustor of a gas turbine engine includes a body section mounted on a ball joint within a standoff cylinder. The standoff cylinder, in turn, is mounted on the casing of the combustor. An electrode tip, extending from the body section if tightly fitted into a hole in the combustor liner. The ball joint permits substantial transverse motion of the electrode tip to fit it through the hole during installation of the igniter, and to track the position of the hole if it should move relative to the casing due to differential thermal expansion during operation of the combustor. Seals between mating parts prevents the leakage of air from the interior of the casing.
