  • Publication number: 20190170706
    Abstract: A method for injecting a diluted sample in a chromatography system includes merging a flow of a sample and a flow of a diluent to form a flow of a diluted sample. A dilution ratio of the diluted sample equals a sum of the volumetric flow rates of the sample and the diluent divided by the volumetric flow rate of the sample. The diluted sample is stored in a holding element before injection into a chromatographic system flow. Sample dilution occurs under low pressure relative to the chromatographic flow thereby allowing lower pressure sample and diluent syringes to be used. Other benefits include reduced compressibility and a reduction in leaks due to the lower pressure operation. The method avoids problems associated with manual techniques which can introduce errors due, for example, to loss of sample, sample precipitation and adsorption of sample to vials.

  • Patent number: 9649676
    Abstract: Method for producing an aluminum foil with integrated security features. An aluminum foil is rolled down to a thickness of less than 150 ?m in a plurality of cold rolling passes, texturing that runs in the direction of rolling being induced simultaneously on both surface sides of the foil. In a final cold rolling pass, the foil is fed to a working roller pair, in which, on at least one roller surface, the relief-like surface structuring generated in the rolling direction by grinding was reduced on the basis of contrast and motif in a region of 10 to 50% relative to the average surface roughness to form a motif for a security feature that is transferred to the surface side of the foil facing the roller surface. The generated aluminum foil has a glossy appearance on both sides such that the security feature rises clearly due to its dull appearance.

  • Publication number: 20160054122
    Abstract: For a simple, fast, safe and reliable determination of the layer thickness of a bonding layer between two layers of a packaging, a laser ultrasonic method is provided, in which the transit time of the ultrasonic wave through the first and second packaging layers (2, 3) is determined in advance, and a maximum (M1, M2, Mn) in the measurement signal (S) is sought, and the point in time of occurrence of this maximum (M1, M2, Mn) is determined as the total transit time (T1, T2, Tn) of the ultrasonic wave, and the transit time of the ultrasonic wave through the first and second packaging layers (2, 3) is subtracted from the total transit time (T1, T2, Tn), and the thickness (d) of the bonding layer is deduced from the known ultrasonic speed (vS) in the bonding layer (5).

  • Publication number: 20140322557
    Abstract: Method for producing an aluminum foil with integrated security features. An aluminum foil is rolled to a thickness of less than 150 ?m in multiple cold rolling passes, and simultaneously a texture which runs in the rolling direction is produced on both faces of the foil. A loose composite formed from at least two of the aluminum foils, is fed into a pair of working rollers in a final cold rolling pass, wherein the relief-like surface structure which is produced in the rolling direction via a polishing process has been reduced by 10 to 50% with respect to the average roughness height in one region in a contrast- and motif-dependent manner on at least one roller surface in order to form a motif for a security feature. The security feature is transferred onto the aluminum foil face facing the roller surface, and the loose composite of aluminum foils is separated.

  • Patent number: 7740730
    Abstract: A lid for closing containers includes an at least two-layered composite assembly. A layer facing the container seals against a container edge and forms an opening by layer separation, for removing contents. The layers have a continuous construction without weakening lines. The layer facing the container is made mainly of a plastic having an intrinsic tearing resistance being lower in the region of the opening than its adhesion to the layer facing away from the container in a remaining region and an adhesion to the container edge being greater at least in the region of an opening aid than to the other layer. The plastic adheres so strongly to the outer layer in the region of the opening that a region corresponding to the opening is torn out upon opening and a remaining layer of the lid facing the container continues to adhere to the container edge by sealing action.
