摘要： A glass forming machine, a method for lubricating a baffle and a swabbing device for a glass forming machine is disclosed. The glass forming machine comprises a blank station with a blank mould for forming a parison from a gob of molten glass inside the blank mould. The glass forming machine further comprises a baffle for closing the blank mould. The glass forming machine further comprises a swabbing device which is configured to spray lubricant onto the baffle for lubricating the baffle. This enables a particularly high quality of the formed parisons and the corresponding glass containers.

摘要： A glass includes from 42 mol % to 47 mol % P2O5, from 42 mol % to 48 mol % CuO, and from greater than 0 mol % to 15 mol % Fe2O3. The glass is an amorphous, single-phase glass. Methods of making a glass article include heating batch materials to a melting temperature from 900° C. to 1350° C. In aspects, methods include pouring the molten glass in an inert gaseous environment, and cooling the molten glass in the inter gaseous environment. In aspects, methods include cooling the molten glass to form the glass article and annealing the glass article without growing crystals in or on the glass article during the cooling or the annealing.

摘要： A method of printing a 3D object includes feeding one or more preformed materials from a feed outlet into a build zone in which a hot spot is located and using the hot spot to selectively heat the one or more preformed materials to a viscous state. Object layers are formed by depositing portions of the preformed materials on a build surface, or on another object layer on the build surface, while effecting relative motion between the build surface and the feed outlet.

摘要： An optical device includes a center section having a lens portion for modifying distribution of a first part of light emitted by a light source, and a peripheral section surrounding the center section and including a conical surface for modifying distribution of a second part of the light emitted by the light source. The conical surface includes ridges where total internal reflection takes place when a light beam arrives from the light source at one of side surfaces of each ridge, and surface penetration takes place when the reflected light beam arrives at the other side surface of the ridge under consideration. Thus, the conical surface acts both as a reflective surface and as a refractive surface for achieving a desired light distribution pattern.

摘要： This invention relates to processes and systems of rapid prototyping and production. Its features includes flexible material deposition along tangential directions of surfaces of a part to be made, thereby eliminating stair-shape surface due to uniform horizontal layer deposition, increasing width of material deposition to increase build up rate, applying the principles of traditional forming/joining processes, such as casting, fusion welding, plastic extrusion and injection molding in the fabrication process so that various industrial materials can be processed, applying comparatively low cost heating sources, such as induction heating and arc-heating. Additional features include varying width and size of material deposition in accordance with geometry to be formed and applying a differential molding means for improved shape formation and surface finishing.
