  • Sealing glass and method of making a Willemite filler therefor
    Patent number: 4522925
    Abstract: A sealing glass composition comprising a lead borate glass matrix and a Willemite filler that provides a blended sealing glass composition with outstanding properties including excellent thermal (button flow and rod seal stress values) and chemical properties. A method of making the Willemite filler is described, the method including critical firing times and temperatures in order to produce the highly effective filler.

  • Method of making a sealing glass suspension
    Patent number: 4444813
    Abstract: Particulate sealing glass material is metered into a mixing container to occupy a portion of the volume of the mixing container. A selected amount of a gel producing vehicle is then introduced to the interior of said mixing container. The mixing container is then agitated for a predetermined length of time to thoroughly interdisperse the vehicle throughout the particulate sealing glass material.

  • Low temperature sealant glass
    Patent number: 4365021
    Abstract: Sealing glass compositions are described which have low sealing temperature requirements and are particularly useful for sealing together the ceramic components used in microelectronic circuitry. The sealing glass compositions are characterized as low temperature, low expansion glasses of high chemical resistance especially against acid attack. Formed of a mixture of a lead borate base glass and beta eucryptite, the sealing glasses of the invention also possess high mechanical and thermal shock strength.

  • Electric power transmission line
    Patent number: 3958074
    Abstract: A high voltage electric power transmission line having an electrical power carrying capacity of 50 megawatts or more. An electrical power conductor is contained within a substantially rigid dielectric casing formed of a plurality of elongated tubular glass casing sections hermetically bonded together linearly end to end forming a continuous elongated casing around the conductor. The casing is loosely contained in an outer duct which permits lateral movement of the casing in the duct but places a maximum limit on such movement.
