Abstract: A multilayer gypsum board forming device, and a gypsum additive delivery system in which additives are delivered to one or more layers of a multi layered gypsum board panels, including engineered polymers, includes at least one additive assembly connected in-line with a first gypsum delivery receptacle for providing an additive fluid feed into the stream of a first gypsum slurry being transported through said first gypsum delivery receptacle for homogenously adding an additive to the first gypsum slurry, and a second gypsum delivery receptacle transporting a second gypsum slurry, in fluid communication with the mixer providing the first gypsum slurry, having a different set of characteristics from those of the first gypsum slurry. At least one outer surface including a polymeric compound or wax emulsion additive entrained therein essentially encases the core gypsum within two facing layers.

Abstract: The present invention provides a system to purify hydrogen involving the use of a hydride compressor and catalytic converters combined with a process controller.

Abstract: Coating compositions, in particular for laser-supported treatment (in particular inscription) of glass surfaces are described, wherein the coating compositions contain at least one silver compound which is soluble in an aqueous and/or organic solvent and contains at least one binder. Methods for producing such coating compositions and methods for coating and treating glass surfaces are also described.
