摘要:
The invention concerns a security element for a security document comprising a structure layer and diffractive first and second relief structures, wherein the relief structures viewed parallel to the plane of the structure layer are arranged in different planes of the security element, wherein the first relief structure adjoins a partial first reflection layer and the second relief structure adjoins a partial second reflection layer, and wherein—if the first reflection layer is towards a viewer—a second item of information generated by the second relief structure is at least partially concealed and—if the second reflection layer is towards the viewer—a first item of information generated by the first relief structure is at least partially concealed, and processes for the production of such security elements and security documents formed therewith.
摘要:
The invention relates to a liquid concentrate for preserving cosmetic products which comprises a combination of carboxylic acid salts chosen from the salts of benzoic acid, propionic acid, salicylic acid, sorbic acid, 4-hydroxybenzoic acid, dehydracetic acid, formic acid or 10-undecylenic acid and alcohols chosen from 2-phenoxyethanol, benzyl alcohol, phenethyl alcohol, 1-phenoxypropan-2-ol, 3-(4-chlorophenoxy)-1,2-propanediol, chlorobutanol or 2,4-dichlorobenzyl alcohol in a solvent, where the active ingredient content is greater than 45% by weight.
摘要:
The invention relates to compositions which comprise one or more glycerol ethers together with one or more diol/diols and/or polyol/polyols. As a result, as well as good microbicidal effectiveness, whitening is reduced or avoided, drying-out of the skin is prevented, the moisture content is regulated and the skin is regressed to an adequate extent.
摘要:
The invention concerns a security and/or value document, in particular a banknote. The security and/or value document has a support (1) of a paper material and an in particular strip-form or thread-form film element (2) which contains one or more optical security features. The support (1) has one or more window-shaped openings (35) which are closed by means of the film element (2) which projects beyond the openings on all sides. Applied to the side of the support (1) of a paper material, which is in opposite relationship to the film element (2), is a sealing layer (4) which covers the surfaces of the film element (2) at least in the region of the openings.

A dental X-ray system includes a radiation source used to produce X-rays and disposed in an X-ray head. The system has an electronic sensor used to detect X-rays. The sensor can be detachably connected to a central unit of the X-ray system by a plug-in connection. The electronic control system for the sensor is integrated into a plug connected thereto by an external connection cable and is associated with the sensor, thereby enabling a simple exchange between two sensors. The system can include several sensors that can be operated parallel to each other.
摘要:
Microbicidal composition for product preservation, including a microbicidal composition which comprises a) at least one formaldehyde donor compound and b) at least one antioxidant chosen from gallic esters, phenol derivatives, L-ascorbic acid, and salts and derivatives thereof, and tocopherols and derivatives thereof, and to the use thereof for the preservation of technical products, for example fuels and lubricants.

摘要:
An apparatus for fixing and centering substrates that are each provided with an inner hole is provided. The apparatus has a housing having an axis that extends perpendicular to the plane of a substrate placed on the apparatus. A fixation unit is guided in the housing and is introducible into the inner hole of a substrate. The fixation unit includes an outer element that is moveable along the axis of the housing and relative to the housing, and also includes an inner element that is moveable along the axis of the housing and relative to the housing and to the outer element, which, by way of a relative movement of the inner and outer elements, is expandable for engagement with the inner hole of a substrate.
