Abstract: The invention relates to a plant and to a process for manufacturing a glass, comprising the production of a main stream of a liquid main glass, by a main plant that includes a main furnace, and the production of an auxiliary stream of a liquid auxiliary glass, by an auxiliary plant that includes an auxiliary furnace having a submerged burner, the auxiliary stream being smaller than the main stream, the auxiliary glass having a composition different from that of the main glass and the two streams then being mixed to form a single total stream of the final glass. The auxiliary furnace especially provides the function of coloring the main glass so that the final glass is a colored glass. A highly homogeneous and bulk-colored flat glass may thus be manufactured by an installation having short transition times.

Abstract: An apparatus and method for treating an undesired presence on an individual includes a CPU coupled to a laser control unit and a robotic arm control unit. A scanning area or volume is defined on the individual that includes the undesired presence. The CPU controls the robotic arm to move the laser and camera about the scanning area or volume while the camera scans individual portions of the scanning area or volume. The CPU receives this information from the camera and determines, based on the scanning, whether a particular portion includes part of the undesired presence. When the particular portion includes part of the undesired presence, the CPU actuates the laser. This process continues for all portions of the scanning area or volume. In an alternative embodiment, the CPU controls the robotic arm control unit to scan the entire area or volume and determines locations where there is an undesired presence.

Abstract: The subject of the invention is a process for melting and refining vitrifiable materials, such that all or part of the thermal energy necessary for melting the said vitrifiable materials is supplied by the combustion of fossil fuel(s) with at least one oxidizer gas, the said fuel(s)/gas or the gaseous products resulting from the combustion being injected below the level of the mass of vitrifiable materials (7). The refining of the vitrifiable materials after melting takes place at least partly in the form of a “thin layer”.
