Abstract: The invention relates to an apparatus for providing marks on extruded films, in particular on stretched films, which are exiting an extrusion lip of a film extruder and a respective method. The apparatus comprises at least one nozzle means for directing a gas stream, preferably an air stream to a surface of the film exiting the extrusion lip of the film extruder, wherein the nozzle means are configured and arranged in such a manner that the gas stream locally causes a cooling of the extruded film to create a local mark.

Abstract: The invention relates to an apparatus for automatically analyzing extruded films, in particular stretched films, wherein a neck-in portion is formed at each of both edges of the film at a specific distance from an extrusion lip of a film extruder along the longitudinal transport direction of the film, and a respective method. The apparatus comprises two edge detectors being arranged along a first line substantially transversal to the longitudinal direction and being spaced from each other by a specific distance, wherein each one edge detector is configured to detect, preferably to continuously detect the lateral position of one respective edge of the neck-in portion of the film, a calculation means for determining the spatial relation between at least one lateral position at the extrusion lip and a respective lateral position at the neck-in portion on the basis of the two lateral positions of the edges of the neck-in portion of the film.

Abstract: A device for directly detecting pressure variations of a fluid within a body cavity is provided. The device has a pressure transducer, a pressure transmission device extending between a distal tip suitable for partial insertion into the body cavity and a proximal port in direct contact with a sensing surface of the pressure transducer. The distal tip forms an access port that places the pressure transducer outside the body cavity into direct fluid communication with the inside of the body cavity. The pressure transmission device has, between the distal tip and the proximal port, a flexible cannula having a length sufficient to allow anchoring of an intermediate stretch of the flexible cannula and/or the pressure transducer to an anchoring zone distant from the body cavity.

Abstract: The invention provides an apparatus for de-vulcanisation of rubber from a rubber component, preferably a rubber tire. The apparatus comprises a cleaning device configured to clean and/or sanitize the rubber and a mixing device having at least one rotor configured to de-vulcanise the cleaned and/or sanitized rubber.

Abstract: The invention provides an apparatus for removing rubber from a rubber component, preferably a rubber tire, wherein the rubber component comprises an outer rubber layer on top of textile components. The apparatus comprises a sensor configured to transmit an electromagnetic signal with a terahertz frequency onto the rubber component, to receive an electromagnetic signal refracted or reflected at the rubber component, and to determine the thickness of the outer rubber layer on top of the textile components based on the received electromagnetic signal and a remover device configured to remove the rubber from the outer rubber layer based on the determined thickness of the outer rubber layer on top of the textile components.

Abstract: The invention provides a apparatus for reworking of non-vulcanised rubber or de-vulcanized rubber from a rubber component, preferably a rubber tire, to produce recycled rubber. The apparatus comprises a gear pump configured to receive and filter the rubber to produce filtered rubber and a mixer-extruder configured to homogenize and extrude the filtered rubber to produce recycled rubber.

Abstract: A device for the direct detection of pressure variations of a fluid within a body cavity comprises a pressure transducer and a cannula having a distal end which either forms or is fluidically coupled with hollow insertion means suitable to be inserted into the body cavity. The cannula and the hollow insertion means form a volume which contains an air column which can be compressed or decompressed by a pressure variation of the fluid inside the body cavity, the pressure variation of the air column being suitable to cause mechanical deformation of the sensing surface.

Abstract: The invention relates to an apparatus (10) for providing marks on extruded films (7), in particular on stretched films, which are exiting an extrusion lip (3) of a film extruder (1) and a respective method. The apparatus (10) comprises at least one nozzle means (13) for directing a gas stream, preferably an air stream to a surface of the film (7) exiting the extrusion lip (3) of the film extruder (1), wherein the nozzle means (13) are configured and arranged in such a manner that the gas stream locally causes a cooling of the extruded film (7) to create a local mark.

Abstract: The invention relates to an apparatus (20) for automatically analyzing extruded films, in particular stretched films (7), wherein a neck-in portion is formed at each of both edges of the film at a specific distance from an extrusion lip of a film extruder along the longitudinal transport direction of the film, and a respective method. The apparatus comprises two edge detectors (31a, 31b) being arranged along a first line substantially transversal to the longitudinal direction and being spaced from each other by a specific distance, wherein each one edge detector (31a, 31b) is configured to detect, preferably to continuously detect the lateral position of one respective edge of the neck-in portion of the film, a calculation means for determining the spatial relation between at least one lateral position at the extrusion lip and a respective lateral position at the neck-in portion on the basis of the two lateral positions of the edges of the neck-in portion of the film.
