Abstract: An apparatus can detect surgical instruments provided with RFID transponders. The apparatus has a receiving space delimited by a bottom and side walls. A surgical instrument can be introduced into the receiving space through an upper side of the receiving space. The receiving space is shielded from external electromagnetic waves at the bottom and at the sides by shielding. An antenna device is configured within the shielding in at least two side walls that extend transversely to one another and/or parallel to one another, in such a way that the antenna device can transmit electromagnetic waves into the receiving space and receive electromagnetic waves from the receiving space with respect to two different sides of the receiving space. An identification device is configured to identify a surgical instrument introduced into the receiving space and store identification data corresponding to the identification of the surgical instrument.

Abstract: A fastening system for a plate-shaped structural element on a pitched roof is provided. The plate-shaped structural element is bordered in a water-tight manner in a frame and fully replaces the roof covering, and the eaves-side and ridge-side cross beams of the frame which run transversely to the ridge-eaves direction have profiles which are matched to each other and engage in each other. The top side of the eaves-side cross beam has a mounting that surrounds the edge of the plate-shaped structural element, and the bottom side thereof has a support for fastening to the roof structure. The support includes a web that extends from the mounting to the support, a protrusion extending beneath the mounting and receives an extension that extends from the ridge-side cross beam thereof.

Abstract: The invention relates to a suction device for liquids in hydroentangling machines, in which more than one water bar, which generate jets of liquid, are allocated to the exterior of the suction device. The suction device consists of a suction tube comprising one or more axial suction openings for each water bar, said openings being located along the working length of the tube. The liquid is sucked from the allocated water bar through said openings as a result of the negative pressure that is created in the tube. According to the invention, the suction openings that extend over the entire working width are configured to be sealed in relation to each respectively allocated water bar.

Abstract: A water needling device has a housing having an intake side and defining a generally horizontal transport direction extending downstream from the intake side. A support in the housing has an upwardly directed foraminous support face. Upstream and downstream reversible winders in the housing spaced apart in the direction flank a plurality of rollers. A textile web passesin the housing along a path starting at the intake, extending over the support face and the rollers, and then downstream out of the housing. A nozzle beam is directed downward at the surface to consolidate the web as it passes over the foraminous face. A threading-in conveyor strand secured to the winders and having a gripper attachable to the textile web extends over at least some of the rollers. This strand is attached at its ends to reversible winders.

Abstract: In a former known hydrodynamic needling device the material web which is meant to be consolidated or finished shall be drawn-in totally or just partly, thus automatically, by an auxiliary material-web drawing-in device. The auxiliary device can work with a frontrunner which is affixed at the beginning of the material web, and which is retracted into the whole machine, or only one part of the non-accessible, if applicable, rollers are driven round by an auxiliary device and the material web is therewith threaded in the provided material-web track.
