Abstract: A method and apparatus for manufacturing a quartz glass ingot of large cross-sectional area by continuous flame-fusion whereby on-line crack-free cutting of the ingot is ensured by using the internal heat of the ingot to permit equilibration of the internal and surface temperatures while passing through one or more annealing chambers, thus ensuring controlled cooling to temperature at which it is possible to cut the ingot with a water-cooled saw.

Abstract: The present disclosure relates to a method and device for cutting glass tubes with a length L from a glass tubing that moves at a feed rate v1. The glass tubing is investigated for defects with an analytical device. The analytical device determines whether a glass tube to be separated is either defect-free (case 1) or contains defects (case 2). In case 1, a defect-free glass tube of the length L is separated from the glass tubing. In case 2, the device and method of the present disclosure determines a distance LA in the lengthwise direction between the defect and a free end of the glass tube to be separated. The distance LA is determined from the portion of the defect at the greatest distance from the free end of the tube. The device and method of the present disclosure then separates a piece of a glass tube or a glass tube that contains defects from the glass tubing at a distance LS from the free end of the glass tube, as a function of LA.

Abstract: A method of forming a glass preform of predetermined length comprises providing a length of glass material to be separated to form a preform length and a remaining length; forming a notch in the glass material; inducing a tensile stress in excess of the tensile strength of the glass in an area adjacent to the notch; and separating the preform length from the remaining length at the notch.

Abstract: Embodiments of the present method of laser cutting a laser wavelength transparent glass article comprises feeding at least one glass article to a pulsed laser assembly having at least one pulsed laser, wherein the pulsed laser defines a laser beam focal line with a length of 0.1-100 mm, the glass article being comprised of two end sections, and at least one lateral surface disposed lengthwise between the end sections. The method further comprises laser cutting at least one perforation line onto the lateral surface of the glass article while there is relative motion between the glass article and the pulsed laser and separating the glass article along the at least one perforation line to yield a laser cut glass article.

Abstract: To produce optical beam splitter cubes, an optically transparent plate is provided with an optically active layer on a cover side. Then, on both cover sides of the plate, a plurality of prism bars are formed by molding an optically transparent material, so that a double prism plate is obtained. The prism bars are arranged on cover sides of the plate projecting roof-like in ridge lines separated from each other by valleys. Each prism bar has the cross section of an isosceles right-angled triangle, complemented by the prism bar lying opposite on the other cover side of the plate to form the cross section of the beam splitter cube. The double prism plate is cut up along the valleys between the prism bars and transverse to the longitudinal direction into segments which in each case form a beam splitter cube.

Abstract: In order to avoid deposition of evaporating alkali compounds on an inner surface of a hollow glass body during thermal processing to form a glass container from the hollow glass body, an overpressure is provided in the hollow glass body during the thermal processing. Either rinsing the hollow glass body with a gas, such as air, or at least partially closing the glass body at one end so that sufficiently rapid pressure equilibration is avoided, can provide this overpressure. The glass containers made by these methods are especially suited for food or pharmaceuticals because they have a reduced alkali release from their inner surfaces, for example at most about 2.0 mg/l sodium oxide.
