Abstract: A method of providing a hermetic, electrical connection between two electrical components by mating at least one metal pin in a glass-ceramic to metal seal connector to two electrical components, wherein the glass-ceramic to metal seal connector incorporates at least one metal pin encased (sealed) in a glass-ceramic material inside of a metal housing, with the glass-ceramic material made from 65-80% SiO2, 8-16% Li2O, 2-8% Al2O3, 1-5% P2O5, 1-8% K2O, 0.5-7% B2O3, and 0-5% ZnO. The connector retains hermeticity at temperatures as high as 700° C. and pressures as high as 500 psi.

Abstract: A frangible rupture disk and mounting apparatus for use in blocking fluid flow, generally in a fluid conducting conduit such as a well casing, a well tubing string or other conduits within subterranean boreholes. The disk can also be utilized in above-surface pipes or tanks where temporary and controllable fluid blockage is required. The frangible rupture disk is made from a pre-stressed glass with controllable rupture properties wherein the strength distribution has a standard deviation less than approximately 5% from the mean strength. The frangible rupture disk has controllable operating pressures and rupture pressures.

Abstract: A method for producing composite materials by introducing additional phases into a porous body wherein a liquid precursor is infiltrated into the porous body, the liquid is decomposed to produce a desired phase, the body is fired for further densification, and the decomposed liquid is allowed to remain as an additional phase or reacts with the porous body to form an additional phase is disclosed. This allows for a novel method of introducing the additional phase, and by controlling the parameters such as infiltration time, firing schedule, porous body density, etc., the size, amount, extent and distribution of the added phases may be controlled.
