    摘要: A rotary cartridge seal is provided which includes a cold flowable plastic ring having a body for sealably engaging the housing bore and a lip for sealably engaging a shaft rotating within the housing bore. A separable metal retainer is provided for fixing the plastic ring within the housing bore and around the shaft with the separable metal retainer having a surface of revolution with a rear portion having a radius suitable for press fitting into the housing bore and a front portion of lesser diameter ending therein. An internal groove is provided into the plastic ring body for engaging the ring therein in order to latch the plastic ring and the metal retainer together with residual stress in both the axial and radial directions within the plastic ring due to groove and ring dimensions and shape.

    摘要: The invention provides a composition and method for reducing structural defects in metastable systems. Structural defects represent spaces or vacancies in the structural order of the metastable system, which can be restored to the predefect order through the use of structure makers. These structure makers will then occupy the space or vacancy of the defect, restoring the order of the system. Lithium ions are used as a preferred structure maker to reduce the structural defects that lead to cataract in a human lens.
