Abstract: The present invention relates to a method for recycling polyester from a polyester textile. The method comprises the steps of: providing said polyester textile soaked in a mixture comprising a solvent and a catalyst, providing and maintaining a temperature of said mixture comprising said polyester textile within a range of 80-240° C. during depolymerization of polyester in said polyester textile and wherein, in said step of providing said polyester textile soaked in said mixture, said catalyst of said mixture comprises calcium oxide. The invention also relates to use of a catalyst for depolymerization of polyester in a polyester textile, wherein the catalyst comprises calcium oxide.

Abstract: The invention relates to an impact machine which is adapted to perform a hammering operation on a surface or an object to be worked upon. In particular, a vibration reduction arrangement is attached to the housing and comprises a moveable counterweight, interacting with a motion reversing arrangement having a non-linear spring characteristics, such that the motion of the counterweight can be brought into a counter-acting movement in relation to the vibrations in the housing of the hammering element thus substantially reducing the vibrations. A spring action arrangement is arranged inside said counter weight, the counter weight being movable a first distance without actuating the spring action arrangement, and the counterweight comprises displaceable projecting member for actuating the spring action arrangement.

Abstract: The invention relates to an impact machine (100, 200) which is adapted to perform a hammering operation on a surface or an object to be worked upon. In particular, a vibration reduction arrangement (140, 240) is attached to the housing (105, 205, 305, 405) and comprises a movable counterweight, interacting with a motion reversing arrangement having a non-linear spring characteristics, such that the motion of the counterweight can be brought into a counter-acting movement in relation to the vibrations in the housing (105, 205, 305, 405) of the hammering element (110, 210, 310, 410) thus substantially reducing the vibrations.

Abstract: The present invention relates to the use of an adaptive protective textile (3) in sheet metalforming, comprising non-woven material which is draped over the active surfaces of the sheet metalforming tool (2), wherein the surfaces of the sheet metal (4) are protected from contact with the surfaces of the tool (2) and the need for lubricant is eliminated.
