  • Patent number: 10442718
    Abstract: A method for producing glass vials, in particular pharmaceutical vials or pharmaceutical ampoules, from a glass tube is provided, the method including the following steps: (a) rotating the glass tube about a longitudinal axis thereof; (b) locally heating the glass tube from one side by means of at least one burner to at least the softening temperature of the glass; (c) reducing the diameter by pressing at least one forming body laterally against the heated region; and (d) separating the glass tube by means of a burner. A glass vial produced in such a way releases a reduced amount of alkali in accordance with ISO 4802 and has a decreased delamination tendency. Furthermore, in the hot-formed peripheral region, the alkali content is only slightly reduced when compared with the alkali content in the glass interior.

    Abstract: A lamp has an LED, a base, and a reflector. The base is rigidly connected to the LED and has a base contact surface. The reflector, which can be connected to the base, has a reflector contact surface, an entry opening, an exit opening, and a longitudinal direction (L) that runs from the exit opening to the entry opening. The reflector contact surface is arranged in the longitudinal direction (L) between the entry opening and the exit opening, and the base contact surface abuts the reflector contact surface. Thus, movement of the base and/or reflector towards each other is prevented when the reflector is connected to the base. The reflector is formed in such a way that a projection of the reflector contact surface in the longitudinal direction (L) of the reflector is free of undercuts.

  • Patent number: 8448471
    Abstract: A processing device is configured to irradiate a laser beam onto a glass substrate for processing. The processing device has a work table, a laser beam output section, a multi-spot focus section, a rotation drive mechanism, an optical system, and a laser beam scan section. The multi-spot focus section receives a laser beam, and splits and focuses the laser beam inputted therein into a plurality of beam focus spots. The rotation drive mechanism rotates the plurality of beam focus spots about a single center axis that is arranged in a center of the plurality of beam focus spots. The optical system guides the laser beam to the multi-spot focus section. The laser beam scan section moves all the plurality of beam focus spots rotating about the single center axis in a desired direction within a predetermined range of a plane arranged along a surface of the glass substrate.

  • Patent number: 8393175
    Abstract: Methods for extracting strengthened glass substrates from glass sheets are described herein. In one embodiment, the method for extracting strengthened glass substrates from glass sheets comprises forming a plurality of channel segments in the glass sheet. The plurality of channel segments may extend through the thickness of the glass sheet and are separated by remnant glass webs connecting the glass substrate to the glass sheet. The plurality of channel segments extend around a perimeter of the glass substrate. Thereafter, the glass sheet is strengthened by ion-exchange. The glass substrate is then separated from the glass sheet by severing the glass substrate from the remnant glass webs.

  • Patent number: 8347651
    Abstract: A method is provided for separating or dividing strengthened glass articles, particularly strengthened glass sheets, into at least two pieces, one of which has a predetermined shape and/or dimension. A flaw is initiated in the glass at a depth that is greater than the depth of the strengthened surface layer of the glass, and a vent extending from the flaw is created at a vent depth that is greater than the depth of and outside the strengthened surface layer to at least partially separate the glass. In one embodiment, the vent is generated by treating the glass with a laser to heat the glass to a temperature in a range from about 50° C. below the strain point of the glass up to a temperature between the strain point and the anneal point of the glass. A glass article having at least one strengthened surface and at least one edge having an average edge strength of at least 200 MPa is also described.

  • Patent number: 8245540
    Abstract: A method of cutting glass that prevents uncontrolled crack propagation when high background stress is present, either in the form of thermal residual stress, external mechanical stress or a combination thereof. The method includes masking an edge of the glass by blocking the beam using highly reflective or absorptive material located near the glass surface, or deposited on the surface in a form of a thin film (or highly reflective paint) to prevent uncontrolled crack initiation and propagation starting from the glass edge. The initiation of the laser scoring is located at a predetermined distance from the glass edge. Yet another aspect of the invention embodies stopping propagation of the vent at the exiting end of the score line.

    Abstract: In a cleaving apparatus (1) for a glass film, an initial crack (10), which is formed at a leading end portion of a preset cleaving line (7) of a glass film (G), is propagated along the preset cleaving line (7) by a thermal stress generated in the glass film (G) through localized heating performed along the preset cleaving line (7) and cooling of a heated region resulting from the localized heating. At this time, a resin sheet (R) having higher flexibility than the glass film (G) is arranged in a cleaving region, and the resin sheet (R) is floated by blowing a gas on a lower surface of the resin sheet (R) by a floating unit (3). Then, a preset cleaving portion of the glass film (G) including the preset cleaving line (7) is lifted and supported while being covered with the floated resin sheet (R) from below, and in this state, the glass film (G) is cleaved.
