Abstract: Method of producing a microstructure in a bioresorbable element comprising a material consisting of a major portion of at least one polymer selected from the group including aliphatic polyesters and aliphatic polycarbonates and copolymers thereof. The microstructure is accomplished by using an excimer laser which is operated at a maximum wavelength of 248 nm.

Abstract: Apparatus for sorting bottles of two or more types. The apparatus comprises a feeding track for unsorted bottles and a number of discharge tracks for the different bottle types and a transporting mechanism in the form of a star wheel. The star wheel is provided with successive bottle pockets each arranged to receive a bottle from the feeding track. Each pocket is provided with a suction cup connected to a vacuum system and corresponding to the contour of one type of bottle for holding such bottle for detachment at a desired later discharge track but leaving the other type of bottle free to travel to a first discharge track.

Abstract: A measuring device is disclosed which can measure an angle or length and which employs either an angle or length measuring plate. The angle or length measuring plate has thereon at least one measuring scale which has a regular pattern along the majority of the lengths thereof and an irregular pattern on two portions thereof. A light beam shines through an optical system to pass through the measuring scale at two points and from there into a photo-detector. The light path is arranged to pass through the two irregular portions at the same time. Several embodiments of the irregular patterns are shown. A circuit is also shown to detect the irregular portions and employ it as a reference signal.
