Abstract: Disclosed is a medical dressing having a pad and a border portion. The pad can have a rim and the border portion extends along said rim. The medical dressing can be arranged in a first substantially planar configuration and be folded along a first line, and a second portion of said medical dressing is formed and a second substantially cup-shaped configuration. The first portion can be facing and contacting said second portion. Said first substantially planar configuration the first and second portions can be connected by means of a fixed connection along a second line, which defines a second line segment having a first and a second end-point. The first and second line segments are connected at their respective first end-points such that an angle between 90 and 175 degrees is formed between the first and second line segments when the medical dressing is in the first substantially planar configuration.

Abstract: A lithography based method for the manufacture of diamond composite materials in which green bodies are prepared by a layer-by-layer construction with resulting green bodies de-bound and sintered to achieve a dense high hardness material.

Abstract: A medical dressing having a geometrical plane of symmetry. A border portion extends along the contour of the pad. A central portion of the dressing has a smaller width perpendicular to the plane of symmetry than the widths of the adjoining portions. The medical dressing comprises a gripping tab which is coplanar with the border portion and which projects outwardly from the border portion. The medical dressing may be used for pressure ulcer prevention, such as at a heel of a human body.

Abstract: A method of producing a component of a composite of diamond and a binder, wherein a Hot Isostatic gas Pressure process (HIP) is used, includes the step of enclosing a de-bound green body having compacted diamond particles in an infiltrant. The method includes the further steps of enclosing the de-bound green body and the infiltrant in a Zr-capsule that has Zirconium as a main constituent and sealing the Zr-capsule, and applying a predetermined pressure-temperature cycle on the unit formed by the de-bound green body, infiltrant and capsule in which the infiltrant infiltrates the de-bound green body and the de-bound green body is further densified in the sense that the volume thereof is decreased.

Abstract: A cBN material and a method of making a cBN material, the method including the steps of providing a powder mixture comprising cBN grains, aluminum and a Ti(CxNyOz)a powder, subjecting the powder mixture to a milling to form a powder blend, subjecting the powder blend to a forming operation to form a green body, subjecting the green body to a pre-sintering step, at a temperature between 650 to 950° C., to form a pre-sintered body, and subjecting the pre-sintered body to a HPHT operation to form the cBN material.
