Publication number: 20120128992Abstract: The invention relates to a method for producing a sheet from renewable raw materials. In the method, after mixing a composition to produce a sheet from renewable raw materials, this composition is applied to a conveyor belt. Protruding materials or unevennesses are eliminated with the aid of a device, preferably a simple doctor blade. Without supplying heat, the composition is then subjected to a first drying process on the conveyor belt, before the endless sheet created in this way is cut into sections. The sections are then passed on to final drying in a storage device. After complete drying, regions at the extremities of the sections that have been adversely affected by cutting up the endless sheet are removed from these sections and chopped up into chips. These chips are returned to the further production process in a final method step by feeding them into the composition for producing a sheet from renewable raw materials.Type: ApplicationFiled: July 6, 2009Publication date: May 24, 2012Applicant: Strohlos Produktentwicklung KGInventor: Christian Loseland

Publication number: 20100285269Abstract: It has been found that basalt particles, when combined with a resin binder and a reinforcing material, such as fiberglass, provide unexpected strength, fire-resistance, radiation impermeability, and projectile shielding for ballistic armor/shields, fire-resistant building panels, construction blocks and protective coatings on substrates. The armor panels can be worn, as in a bullet-proof vest, or can be used as a shield to protect a vehicle, aircraft or other structures as projectile penetration-resistant and fire and radiation resistant materials.Type: ApplicationFiled: November 3, 2008Publication date: November 11, 2010Applicant: U.S. WIND FARMING, INC.Inventor: William Telander
