Abstract: A fiber cushion body, which is formed from cross-linked fiber material and which is resiliently deformable when load is applied along a main load direction, is treated using ultrasonic energy. A portion of the fiber cushion body is displaced, for example using a sonotrode, and ultrasonic vibrations are applied to the fiber cushion body to re-shape the fiber cushion body from a first shape to a second shape different from the first shape.

Abstract: A seat cushion body and method of producing the same are provided. In a method of producing a seat cushion body, fiber material is inserted into a mold. Heat is supplied to the fibers to cause thermal activation of binding fibers, so as to effect thermal cross-linking. The resulting seat cushion body includes a resilient portion formed from the fibers and having a fiber orientation along a main load direction of the seat cushion body. The seat cushion body may include at least one further portion formed from the fibers, which has a fiber orientation and/or a density different from the fiber orientation and/or different from a density of the resilient portion. The resilient portion and the at least one further portion may be integrally formed from the cross-linked fiber material as a unitary body.

Abstract: The present invention pertains to a method for isolating nucleic acids by size from a sample comprising nucleic acids of different sizes using an anion exchange matrix, wherein nucleic acids of a preselected size or a preselected size range are isolated by varying the pH value during elution and/or binding.
