  • Publication number: 20190016623
    Abstract: The invention relates to a method and a device for separating the excess glass (32) in the production of hollow glass products (12), wherein the method comprises: centring a hollow glass product (12) in a receiving device (10), which is designed to hold the hollow glass (12) and to rotate about a rotational axis in such a way that a separation line (24) along which the excess glass (32) is to be separated from the hollow glass product (12) to be produced is centred in relation to the rotational axis; processing the hollow glass product (12) in a plurality of positions along the separation line (24) by means of a laser beam in order to generate local filaments with a weakened glass structure during a rotation of the hollow glass product (12) about the rotational axis; and introducing energy along the separation line (24) in order to separate the excess glass (32) along the weakened glass structure.

  • Patent number: 9527762
    Abstract: An apparatus for pressing glass preforms and placing the glass preforms into a blowing machine is provided. The apparatus includes a first plunger configured to be reciprocated between a gob-receiving region and a first preform-pressing region, a second plunger configured to be reciprocated between the gob-receiving region and a second preform-pressing region, a first press mold associated with the first plunger and configured to be reciprocated between the first preform-pressing region and a preform-placing region, and a second press mold associated with the second plunger and configured to be reciprocated between the second preform-pressing region and the preform-placing region. The respective plungers are configured interact with the respective associated press molds in the respective preform-pressing regions such that a gob received in the gob-receiving region by one of the respective plungers is formed into a glass preform and received by the respective associated press mold.

  • Patent number: 8783064
    Abstract: The method for polishing glass products, comprises the following steps: specifying a contour or form or shape of the glass product; detecting the location or position of the glass product; calculating a path for a laser beam on the basis of the contour of the glass product and the location of the glass product; and scanning the path with the laser beam for polishing the glass product in order to fuse mold joints together or smoothen/polish them.

  • Patent number: 8250946
    Abstract: A vehicle, comprising a brake operating lever, mounted to pivot on a lever bracket, a coupling unit, which couples a brake cable to the brake operating lever, a locking device with teeth and a locking bolt, tensioned against the teeth by means of a first spring element and a release unit, with at least one first lever, said locking bolt and the first lever having an articulation. A parking brake which permits a secure braking and release and also avoids making noise on operation and on releasing may be achieved, whereby the articulation for the locking bolt and the first lever is arranged on the lever bracket and the articulation is provided on the lever bracket in a displaceable manner.

  • Patent number: 8122740
    Abstract: The invention relates to a method for the generation of raised and/or recessed structures on workpieces comprising the steps: applying a pressure difference between one side of a wall of the workpiece and another side substantially opposite thereto; local heating of the wall of the workpiece to a softening temperature of the workpiece by a heat source in order to induce local deformation of the wall of the workpiece; and cooling of the workpiece. The invention relates, moreover, to an apparatus for carrying out this method.
