Abstract: The present disclosure relates to a method for establishing the suitability for printing of a thermoplastic film for use in a packaging of absorbent hygienic articles, said thermoplastic film comprising at least 30% recycled polymer material. The method comprises scanning a sample of said film for Gel Spots, defining an Amount of Gel spots and a Relative Gel Spot Coverage area, and, determining that if the Amount of Gel Spots is less than or equal to a first threshold and the Relative Gel Spot Coverage Area is less than or equal to a second threshold, determining that said thermoplastic film is suitable for printing. The disclosure also relates to a method of forming a package from a thermoplastic film, and to a package comprising a thermoplastic film.

Abstract: A substrate for use in providing an ionized target comprising a structured substrate has a plurality of recesses, at least a portion of the plurality of recesses containing an initiator, the substrate being capable of having a target loaded on it. In one methods, irradiation of the substrate can cause the initiator to restructure, releasing it from the recesses and thereby desorbing and ionizing the target. The target so desorbed and ionized can be detected by mass analyzers. The mass of the targets at a given point on the surface can be recorded to provide a spatial mapping of the targets on the surface.

Abstract: The invention relates to a backspot facing tool for machining operations. At least one cutting fluid jet is used to actuate a cutter included in the tool, causing it to move from a retracted to a non-retracted position.

Abstract: In a game having magnetically operable pieces (3) there are below a game board (2) several operating devices (4) for operating the pieces, these operating devices being separated by intermediate layers (7) that are parallel to the game board. The intermediate layers are thin and easily flexible and rest on top of each other, the game board resting on top of the top intermediate layer. A specially designed piece is included in the game, intended for contact with the game board. This piece has two supports (9, 10) e.g. the feet of a human figure. One (9) of the supports rests on and carries a magnet (8) that can be moved by a cooperating magnet (13) beneath the game board. The other support (10) has a supporting surface (11) of friction material.

Abstract: A rebound apparatus for practicing striking a ball with a racket. The apparatus has an elongated rectangular frame which is mounted on a base for pivotal adjustment about a horizontal axis. Mounted on the frame is a flexible material which is relatively loose along the width of the frame and relatively taut along the length of the frame. The upper end of the frame is curved out of the plane of the main portion of the frame, and this upper end supports a ball rebound surface. The flexible material may be secured at its upper end to the rebound surface. The length of the frame is adjustable. In use, a ball when hit by a racket will strike the flexible material, rebound upwardly against the ball rebound surface, and then rebound again in a direction back toward the player who hit the ball.
