Abstract: The present invention relates to composition at least including (A) at least one epoxy-group terminated polyoxazolidinone, derived from at least one polyisocyanate compound and at least one aliphatic polyepoxide compound, (B) at least one compound having at least one group that is reactive towards terminal epoxy-groups, and (C) at least one solvent. The molar ratio of the epoxy groups of the polyepoxide compound to the isocyanate groups of the polyisocyanate compound is 50:1 to 2.4:1. The at least one epoxy-group terminated polyoxazolidinone is present in an amount of 50 to 95% by weight, in respect of the solid content of the composition. The sum of all components in respect of the solid content of the composition adds up to 100% by weight and where the solid content of the composition is at least 35% by weight.

Abstract: A system for determining a position of a light fixture that projects a beam of light on to a stage to form a first beam pattern on the stage includes an observing device located at a predetermined position relative to the stage to observe the first beam pattern. The system also includes a controller in communication with the observing device. The controller is configured to capture from the observing device an image of the first beam pattern on the stage, determine a major dimension and a minor dimension of the first beam pattern from the image, and calculate a position of the light fixture based on the major dimension and the minor dimension.

Abstract: A tool for chip removing machining, including a basic body and two replaceable cutting inserts. Each insert includes a chip-removing main edge situated between a chip surface and a clearance surface, a first insert of which precedes a second insert during machining of a workpiece. The cutting inserts overlap each other in a zone defined by a borderline along which a surface generated by the main edge of the first cutting insert, with a time delay, is intersected by the main edge of the subsequent, second cutting insert. The main edge of the second cutting insert that afterwards intersects the already generated surface, is formed along a chip surface including primary and secondary sections, which have different shapes in cross-sections spaced-apart along the main edge in order to form a primary part edge and a secondary, reinforced part edge arranged to intersect the already generated surface.

Abstract: A method and cutting tool for producing a hole or a recess in a workpiece which includes flat or curved sheets of fiber-reinforced composite material, metal or combinations thereof. The cutting tool has a shaft with a longitudinal axis and an axial cutting surface and at least one cutting edge disposed on the axial cutting surface and extending radially from the longitudinal axis with a gap between the radial inner extent of the cutting edge and the longitudinal axis. The method of use includes rotating the cutting tool about its longitudinal axis and also translating the cutting tool during rotation.
