Publication number: 20110298157Abstract: In a method for cleaning profile molds for producing tire profiles on treads of vehicle tires, the profile molds are cleaned in rinsing suds by using ultrasound. The profile molds are moved successively through a pre-cleaning and a primary cleaning chamber between which they are rinsed in a rinsing bath. After cleaning in the primary cleaning chamber, the profile molds are checked with respect to remaining contaminants and valves disposed in air vent openings in the profile molds are inspected and loosened by ultrasound application to ensure their mobility. Subsequently, the profile molds are cleaned again. The invention also relates to an arrangement for carrying out the method.Type: ApplicationFiled: August 10, 2011Publication date: December 8, 2011Inventor: Horst Vossen

Patent number: 7955547Abstract: The inventive method for forming articles from foaming polymers and compositions based thereon consists in forming articles using a heat energy released by water exposed to the action of microwave radiation al n temperature equal to or less than 170° C., wherein said temperature is attained, controlled and limited by adjusting a vapor pressure in a forming chamber. The inventive device for carrying out said method comprises a forming chamber, which is made of a microwave transparent material, filled with the mixture of prefoamed or granulated foaming polymer or a composition based thereon with water and is placed in a microwave radiation producing channel, and a unit for equalizing a pressure in said forming chamber. The forming chamber and the body thereof made of a microwave non-transparent material are provided with air holes, which are also used for connecting the forming chamber to the pressure equalizing unit.Type: GrantFiled: November 16, 2006Date of Patent: June 7, 2011Assignee: ZAO “Elefom’Inventors: Andrey Nikolaevich Plaksunov, Igor Nikolaevich Golubev

Patent number: 7887739Abstract: An improved method of imprint lithography involves using fluid-induced pressure from electric or magnetic fields to press a mold onto a substrate having a moldable surface. In essence, the method comprises the steps of providing a substrate having a moldable surface, providing a mold having a molding surface and pressing the molding surface and the moldable surface together by electric or magnetic fields to imprint the molding surface onto the moldable surface. The molding surface advantageously comprises a plurality of projecting features of nanoscale extent or separation, but the molding surface can also be a smooth planar surface, as for planarization. The improved method can be practiced without mechanical presses and without sealing the region between the mold and the substrate.Type: GrantFiled: October 30, 2007Date of Patent: February 15, 2011Inventors: Stephen Y. Chou, Wei Zhang

Publication number: 20100327470Abstract: The invention relates to a process for producing plastic components, in particular optical lenses or optical light-guides, wherein plastic melt is injected via a sprue (3, 4, 6, 8) into a cavity (1) of a moulding tool shaping the component and additional plastic melt is after-pressed into the cavity (1) for the purpose of compensating a volume contraction of the injected plastic melt due to cooling. The process is characterised in that the plastic melt located in the sprue (3, 4, 6, 8) is kept flowable by means of energy introduced in the region of the sprue until such time as the molten core of the plastic component has solidified in the course of the after-pressing of plastic melt for the purpose of compensating the volume contraction due to cooling (holding-pressure). The invention further relates to an apparatus for implementing the process.Type: ApplicationFiled: June 25, 2010Publication date: December 30, 2010Applicant: Bayer MaterialScience AGInventors: Rainer Protte, Christoph Klinkenberg
