    摘要： A process for the vertical drawing of glass tubes, optionally with safety strips, sealed bottoms, and, if desired, a pressure equalizing aperture wherein specific tube lengths are severed in succession from a continuous glass tube rod. The glass tube rod, closed at its beginning and exiting through a feeder head from a vessel which contains molten glass, is introduced, being under atmospheric pressure in the interior of the glass tube rod, in the still plastic condition into a pressure tank located downstream of the feeder head where the glass tube rod is exposed to a defined pressure and is conducted on a non-plastic condition out of the pressure tank by drawing. Thereafter, by heating the glass tube rod at an interval after leaving the pressure tank, a specific tube length is severed from the continuous glass tube rod essentially simultaneously with the formation of bottoms that seal the melted-off tube length and the continuous glass tube rod.

    摘要： This application teaches a method of producing an article of glass by cutting it out of a sheet of flat glass. Flat glass is formed in a glass ribbon forming apparatus and is discharged therefrom at a temperature in excess of 1000.degree.F. The hot flat glass is moved under at least a pair of focused laser beams which cut patterns in the glass having a common starting and ending point. In such a manner, a glass article is cut from the ribbon. The article is removed from the remaining portion of the ribbon and cooled in a controlled manner to produce a final glass article. The cooling operation may be rapid or slow so as to produce a tempered or an annealed article.

    摘要： A method for producing perforated work pieces from glass, glass ceramics, or semiconductors in a stress-relieving manner is provided. The method includes heating the work piece up to the glass transition temperature and perforating the work piece using a high-voltage electric field of suitable frequency or pulse shape. Then, the perforated work piece is allowed to cool down from the transition temperature range to room temperature at a rate at which the mechanical stresses generated by the perforation process relax.

    摘要： The present invention relates to a float process for manufacturing glass sheets, in which molten glass is poured onto a liquid support denser than the glass and then the continuous ribbon which forms is advanced toward the downstream end, this process being characterized in that the thickened edges of the ribbon are trimmed continuously in the forming zone. This process makes it possible to obtain thin glass sheets, such as sheets of film glass, with good flatness, particularly in small plants. The invention also relates to a plant for implementing the process and to the products obtained. FIG. 1.

    摘要： A method of making an at least one hole in an optically transparent body comprises the following steps: (i) providing an ultrashort pulse laser for producing a laser output with a wavelength λ, the laser output having a subpicosecond laser pulse duration; (ii) providing a laser output focusing lens for focusing the laser output, the focusing lens having a numerical aperture NA; (iii) providing an optically transparent body, the optically transparent body having a transparency at λ of at least 90%/cm; (iv) providing a liquid filled container situated proximate to the optically transparent body, such that the optically transparent body is in direct contact with the liquid; and (v) directing the laser output through the focusing lens to produce a focused laser output with a subpicosecond laser pulse duration proximate the optically transparent body, wherein the focused laser output traces at least one hole track pattern through the transparent glass body while the optically transparent body and said focused laser output move relative to one another in X-Y-Z directions. The at least one hole track pattern is in contact with the liquid and the focused laser output, in conjunction with the liquid, creates at least one hole in the optically transparent body.
