  • Patent number: 9107805
    Abstract: A container for pharmaceutical and medical applications made from glass, preferably from a borosilicate glass. The container is formed in the shape of a hollow body open at both its ends with a cylindrical portion having a wall thickness tolerance of maximally ±0.2 mm. The borosilicate glass has a nominal boron content that drops by less than 40% relative to the nominal value at all of the surfaces of the container.

  • Patent number: 8464553
    Abstract: The invention proposes a process for the production of a container for pharmaceutical and medical applications made from glass, preferably from a borosilicate glass, wherein the container is produced by a press-blow process where the container is initially preformed in a pressing step, by making a ram press a dispensed glass drop into a mold that is open at its bottom, and where the parison so produced is given its final form by a subsequent blowing step.

  • Patent number: 8158225
    Abstract: The invention proposes a process for the production of a container made from glass, in the form of a hollow body open on both ends for pharmaceutical and medical applications, in particular in the form of a syringe barrel, where a glass drop (14) is dispensed from a melting unit, is placed into a mold (12) that is driven to rotate, and is formed by the effect of the centrifugal force, the mold being driven at a rotational speed of at least 5000 rpm, preferably approximately 50000 rpm.

  • Patent number: 8104309
    Abstract: The method provides an improved quartz glass body, especially an improved quartz glass crucible for melting non-metals, non-ferrous metals, or silicon. The quartz glass body is made by a method in which a quartz glass-water mixture is supplied to a gypsum casting mold comprising an outer part and an inner part, dried in the gypsum mold, and put under an overpressure via a system of ducts in the form of textile tubes embedded in the mold during the drying. Later a resulting green glass body is removed from the mold. At least a portion of the shaping surfaces of the inner part of the gypsum mold are surfaces of a water-impermeable substance. The method provides a cast body with a reduced tendency to crack and with a smaller open porosity.

  • Publication number: 20100199720
    Abstract: The apparatus (300) for feeding, homogenizing, and conditioning a high viscosity glass melt for manufacturing display glass has a stirring device (110, 406), an upstream connecting part (100, 400) that connects the stirring device (110, 406) to an upstream melting and/or refining unit, and a downstream connecting part (120, 420) that connects the stirring device (110, 406) to a downstream forming or shaping device. Wall material and base material of the first and connecting parts and the stirring device (110, 406) coming in contact with the glass melt are made from a zirconium-dioxide-containing fire-resistant material containing a large amount, preferably more than 85 wt. %, of zirconium dioxide. A method of operating the apparatus to make display glass is also described.
