An apparatus for mass production of 3D articles from 2D glass-containing sheets includes a heating section having a heating station that includes a heating chamber adapted to receive a 2D glass-containing sheet, a pneumatic bearing system proximate to the heating chamber for suspending the 2D glass-containing sheet inside the heating chamber, and a heater system proximate to the heating chamber for supplying heat to the heating chamber. A forming section downstream of the heating section has a forming station that includes a mold system adapted to shape a heated 2D glass-containing sheet into a 3D article. A cooling section downstream of the forming section has a cooling chamber adapted to controllably cool off one or more 3D articles. A method of mass producing 3D articles from 2D glass-containing sheets involves use of the apparatus.

Apparatus and method for mass producing 3D articles from 2D glass-containing sheets

Disclosed in the present application include: (i) plates, having two approximately parallel main sides, of a glass-ceramic or a glass displaying a certain transparency, with a colored coating fixed to at least one part of the surface of one of said two main sides; (ii) heating plates, particularly cook-tops, consisting of such plates or obtainable from such plates. These heating plates are intended to be fitted above heating elements, their side bearing said coating facing said heating elements; and (iii) the preparation of such plates. The original colored coating proposed is particularly interesting with reference to its color stability.

Temperature stable and sunlight protected photochromic articles

The invention relates to photochromic transparent organic materials particularly useful for the production of photochromic organic ophthalmic lenses. The material includes an optical-quality polymer matrix and at least one coloring agent giving photochromic properties to the matrix. The coloring agent is chosen from the group of the spirooxazins the spiropyrans, and the chromenes. The polymer of the matrix is chosen from the group of homopolymers of ethyoxylated bisphenol A dimethacrylate with formula I:
