    摘要： The invention relates to a method and a device for producing a technical glass part with high requirements in terms of definition and surface finish, in particular a precision lens. In said method, a blank (41) with a moulded-on sprue (42, 43, 44) is produced by means of an injection pressing process, wherein the blank (41) is cooled and subsequently heated, and wherein the blank (41) is subsequently blank-pressed, in particular on both sides, to form a technical glass part with high requirements in terms of definition and surface finish, in particular a precision lens. The invention also relates to a method, wherein a blank is cooled and subsequently heated in such a way that the temperature gradient of said blank is reversed.

    摘要： A method and system for coating a glass contacting surface with a thermal barrier and lubricious coating. The system uses a novel exterior surface mixing tip device (1) wherein oxygen is supplied through a predetermined portion of one supply line (3), and a predetermined gas is supplied through a predetermined portion of another supply line (4) enveloping the first predetermined portion. Each supply line consist of a regulator (7,8), throttle valve (9,10), flow meter (11, 12), check valve (13, 14), control valve (15, 16), three-way valve (17,18) and back flash valve (19, 20). Oxygen and gas do not mix until they reach the tip (6) of the mixing tip device (1).

    摘要： The present invention relates to low-dispersion optical glass having a low glass-transition temperature suited to precision press molding, a press molding preform comprised of this glass, a method of manufacturing the same, an optical element, and a method of manufacturing the same. The optical glass comprises, given as molar percentages,28 to 50 percent of P 2 O 5 ; more than 20 percent but not more than 50 percent of BaO; 1 to 20 percent MgO; a sum of Li 2 O, Na 2 O, and K 2 O exceeding 3 percent (with 0 to 25 percent of Li 2 O, greater than or equal to 0 percent and less than 10 percent of Na 2 O, and 0 to 12 percent of K 2 O); more than 0 percent but not more than 15 percent of ZnO; 0 to 25 percent of B 2 O 3 ; 0 to 5 percent of Al 2 O 3 ; 0 to 8 percent of Gd 2 O 3 ; 0 to 20 percent of CaO; 0 to 15 percent of SrO; and 0 to 1 percent of Sb 2 O 3 ; with a sum of oxide contents of P, Ba, Mg, Li, Na, K, Zn, B, Al, Gd, Ca, Sr, and Sb being greater than or equal to 98 percent. The press molding preform is comprised of the optical glass. In the method of manufacturing a press molding preform, a glass melt gob of prescribed weight is separated from a glass melt flow, and the press molding preform comprised of the optical glass is formed with the prescribed weight. In the method of manufacturing an optical element, the press molding preform or the press molding preform manufactured by the above method is heated and precision press molded.

    摘要： The invention relates to an assembly of a device for cooling a mold, the cooling box (2), and the mold 1. Such a mold (1) for forming glass, such as glass parts for a display tube (for example, screen and cone) is cooled by causing a cooling medium such as water or air to flow around this mold (1). The cooling medium is distributed along different parts of the mold (1) by means of the cooling box (2). The cooling box (2) according to the invention is adapted in such a way that the tangential component of the flow of the cooling medium is substantially equally directed throughout the channel (3). A method of achieving this is a tangentially oriented inflow of the cooling medium into the channel, instead of the conventional radial inflow. This tangential inflow causes a rotating flow in the channel (3), referred to as vortex or whirl, so that differences in inlet conditions are averaged and a uniform pressure distribution in the channel (3) is obtained. A more homogeneous cooling of the mold (1) can be obtained in a simple manner with the assembly according to the invention.
