20090115099	Process for making a monofilament-like product - The invention relates to a process for making a monofilament-like product from a precursor containing a multitude of continuous polyolefin filaments, comprising exposing the precursor to a temperature within the melting point range of the polyolefin for a time sufficient to at least partly fuse adjacent fibres and simultaneously stretching the precursor at a draw ratio of at least 2.8. With the process according to the invention a monofilament-like product can be made that shows improved tensile properties; making it very suitable for application as e.g. fishing line.	05-07-2009

20090022951	SINGLE CRYSTAL DIAMOND ELEMENTS HAVING CONVEX SURFACES AND METHODS OF ITS FABRICATION - A single crystal diamond element having a convex surface is disclosed, the convex surface including a spherical segment for which the maximum peak to valley deviation from a perfect spherical surface is less than about 5 μm. Alternatively or in addition, the RMS deviation from a perfect spherical surface may be less than about 500 nm, or the RMS roughness less than about 30 nm. A single crystal diamond element with a radius of curvature less than about 20 mm is also disclosed. In one aspect a single crystal diamond element having a conical half-angle greater than about 10° is described. The invention also provides a method for forming a rotationally symmetrical surface on a single crystal diamond element, comprising rotating the element about a first axis, applying a laser beam to the element in a direction perpendicular to the first axis, and translating the laser beam in two dimensions in a plane perpendicular to the direction of the beam. If the two-dimensional path follows the arc of a circle a spherical surface may be formed. The invention also provides improving a spherical surface on a single crystal diamond element by pressing a rapidly rotating cup onto a slowly rotating element. The element may be a lens, in particular a solid immersion lens.	01-22-2009
