The invention relates to a packaging machine for packing food products in a plastic packaging, said machine comprising a device for applying a transponder to the plastic packaging, and a system for data exchange between the transponder and a computer unit and/or a regulating unit, by which means data can be transmitted to the transponder or called therefrom.
摘要:
The present invention relates to a packaging machine with a forming station, which forms depressions in a sheet of film, wherein a heating element heats the sheet of film before the deforming, in which the heating element has a multiplicity of discrete heating means which can be activated individually or in groups, and so the sheet of film has temperature gradients.
摘要:
The present invention relates to a film, further comprising a radiation-curing coating, wherein the coating comprises a polyurethane polymer which contains (meth)acrylate groups and which is obtainable from the reaction of a reaction mixture comprising (a) polyisocyanates and (b1) compounds which comprise (meth)acrylate groups and are reactive towards isocyanates and wherein the coating further comprises inorganic nanoparticles with an average particle size of ≧1 nm to ≦200 nm. It also relates to a process for the production of such coated films, the use of such films for the production of shaped articles, a process for the production of shaped articles with a radiation-cured coating and shaped articles which can be produced by this process.

The invention proposes sensor elements (5) for detecting a physical measurement variable such as a pressure, a temperature, a gap width, or a capacitance between two bodies (10, 20) that move in relation to each other during operation and experience high tribological stress. In certain areas between the surfaces of the bodies (10, 20) that move in relation to each other, in a surface region of at least one of the bodies (10), a sensitive layer (13, 30), in particular a sensor segment (13), is provided, which is separated from the body (10) by an insulation layer (12) and has a covering layer (14) in a first embodiment. In an alternative embodiment, a surface region of at least one of the two bodies (10) has a recess (23) in which the sensor surface (13) is disposed on the insulation layer (12). In a third embodiment, the sensor surface (13) has a length of 10 μm to 5 mm, a width of less than 5 μm, and a thickness of less than 200 nm.

摘要:
A thermoplastic molding composition suitable for the preparation of sheets, in particular for making diffuser sheets in flat screens is disclosed. The composition that contains 80 to 99.9% of a transparent thermoplastic material and 0.01 to 20% of scattering pigments in the form of polymeric particles having average particle diameter of 1 to 100 μm. is distinguished by a particularly low fines content of the scattering pigments.
摘要:
A solid sheet comprising transparent polycarbonate matrix, particles of a transparent polymer and an antistatic agent is disclosed. Characterized in that the refractive index of said matrix differs from that of said polymer, the sheet is suitable in making diffuser plate in flat screens.
摘要:
A method for producing a profiled part from a blank, wherein the cross-sectional profile of the part to be produced differs in some portions both quantitatively and qualitatively from the cross-sectional profile of the blank, so that different amounts of material must be removed between a starting profile of the blank and a desired final profile of the part includes pre-shaping and finish-grinding the part to be produced in one chucking position with at least one profiled grinding wheel. The blank is translated and rotated relative to the at least one profiled grinding wheel during the pre-shaping step for giving the blank approximately a desired profile. The finish-grinding step is performed at least partially after the pre-shaping step for smoothing surfaces and producing the final profile to accurate dimensions. A turbomachine blade, an intermediate product for the turbomachine blade and a method of manufacturing the interim product are also provided.
