    摘要: The present invention relates to a prepreg composite and to a process for manufacturing the prepreg composite. The manufacturing process involves surface treatment and impregnation of a high tenacity fibrous material with a surface treatment agent and a polymer matrix resin material. The fiber may be in the form of a woven, unidirectional or non-woven fabric. The fiber may optionally be coated with a surfactant and/or an adhesion promoter. Prior to treatment, the surface treatment materials may be contained in a dispersion of nano-particles in which each material has a film forming process temperature at a value below the degradation temperature of the fiber. The layers may be applied individually or simultaneously onto the fibers. The coated material is heat dried without compression to form a prepreg composite.

    摘要: A method and apparatus for exposing photosensitive recording material is presented. The invention provides for using chromatic lenses to focus polychromatic light onto recording media. The resulting chromatic aberrations contribute to exposing recording media in three dimensions. The method and apparatus presented also provide for improved quantum efficiency in the exposure of photosensitive recording material.

    摘要: Subjacent and lateral supporting soil for an underground tank is stabilized wherein a tank embedded therein is secured against flotation irrespective of the water table level of the surrounding soil. The lateral supporting soil is encased within a well and the subjacent soil is hardened to minimize seepage of water into the soil adjacent to the tank. Means are also provided to remove excess water from the confines of the well thereby minimizing flotation pressure on the tank.
