  • Method and device for optical examination of transparent bodies
    Patent number: 11049237
    Abstract: A method and a device for optical examination of transparent bodies made of plastic, glass, or glass ceramic are provided. The examination is carried out by contactless detection and measurement of the body using optical imaging devices. For this purpose, a plurality of individual images are taken of the body during the examination in different positions relative to the imaging device, which are subsequently analyzed.

  • Pharmaceutical and medical container
    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.

  • Production of a pharmaceutical container from the melt
    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.

  • Production from the melt of a container made from glass
    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.
