Abstract: A system for levitating a softened, viscous or viscoelastic material by near field acoustic levitation. The system includes a support structure having a rigid surface, and a vibration generator operatively connected to the rigid surface. The vibration generator transmits acoustic waves to the rigid surface at a frequency and an amplitude sufficient to vibrate the rigid surface and create a gas squeeze film between the material and the rigid surface. The gas squeeze film has a pressure greater than ambient air pressure and sufficient to levitate the material. The system is particularly suited for transporting, forming, or casting heated glass. Also disclosed are methods for transporting, forming, and casting heated glass using near field acoustic levitation.

Abstract: A mold has a sealing surface bearing a sealing profile. A plenum has a sealing surface bearing a sealing profile. The mold and plenum together form an apparatus for reforming a sheet material. In the closed position of the apparatus, the sealing profile of the mold is in opposing relation to the sealing profile of the plenum and the sealing profiles of the mold and plenum together define a profiled sealing gap. When the sheet material is wedged into the profiled sealing gap, a direct seal will be formed between the sheet material and each of the mold and plenum, resulting in two forming areas within the apparatus.

Abstract: A method of making articles from preformed materials includes placing a preformed material on a mold such that a non-quality region of the preformed material contacts the mold and a quality region of the preformed material is free of contact with the mold. A non-contact support is provided to the quality region to control sagging of the quality region. A reformable area of the preformed material is formed into a select shape by contacting the reformable area with a forming tool while restricting contact between the forming tool and the reformable area to the non-quality region. After the forming of the reformable area, an article is extracted from the quality region.

Abstract translation: 模具具有密封表面，其具有密封轮廓。 气室具有密封表面，其具有密封轮廓。 模具和集气室一起形成用于重整片材的装置。 在装置的关闭位置，模具的密封轮廓与气室的密封轮廓相对，并且模具和气室的密封轮廓一起限定了异型密封间隙。 当片材楔入成型密封间隙时，将在片材和模具和增压室之间形成直接密封，从而在装置内形成两个成形区域。
