摘要:
A method is provided for the quantitative determination of surface properties, wherein a spatially resolved image of a surface to be analyzed, which contains a large number of measured values, is recorded. In a first method step, the measured values are analyzed in order to determine those surface areas which have a specific physical property. A result value of this physical property is then determined, wherein this result value is characteristic of the values of the physical property of all those surface areas of the image determined by analyzing the image. In addition to the result value, a further value (B) characteristic of the surface is determined and this characteristic value is displayed together with the result value (I).

The present invention relates to a polymer composition containing polycarbonate with a weight-average molecular weight Mw of from 24,000 to 33,000 and 5.0 wt. % to 20.0 wt. % (based on the total amount of the composition) of glass hollow spheres with an alkalinity of less than 1.0 meq/g. The present invention furthermore provides coextruded sheets in which the coextruded layer contains this polymer composition, and shaped articles produced therefrom, in particular containers and pieces of luggage, very particularly suitcases. Sheets which are obtainable with the polymer composition according to the invention have a high mechanical stability, a high scratch resistance, pleasant haptic properties and an excellent homogeneous external visual impression. The present invention furthermore relates to a process for the preparation of these polymer compositions and a process for production of the sheets according to the invention.

A method of determining optical properties of textured surfaces by irradiation of the surface to be investigated. At least part of the radiation irradiated onto the surface and reflected by the latter is detected by a detector device which permits a location-resolved evaluation of the radiation striking it. A first characteristic value from the radiation detected, characteristic of a texture of the surface is detected. A second characteristic value from the radiation detected, characteristic of a further optical property of the surface is detected. And, a result value is determined on the basis of the first characteristic value and the second characteristic value.

摘要:
The present invention relates to methods by which to produce sheet-like, wafer-like or film-like forms of drugs, confectionary, other food, cosmetics and the like for oral application or intake. The present invention is more particularly directed to the thermal treatment of carrier materials used in the production of such sheet-like, wafer-like or film-like forms. The thermal treatment removes contaminating or undesired substances from the carrier material.

Methods for producing a mono- or multilayer composite are provided in which one or several layers are applied onto a carrier material by coating, the coated mono- or multilayer composite is dried and rolled up, and the installation is subsequently cleaned. The air circuit in the drying oven is entirely set to fresh air supply, and the drying oven is configured to be cleaned in a controlled manner. All components of the drying oven that come into contact with the product do not have to be removed during cleaning, but can be cleaned-in-place using technology integrated into the drying oven. The drying oven Outer housing is designed so that it can be lifted upwardly. All assembly parts in the drying oven interior are designed to eliminate disassembling for cleaning purposes. Transport rollers within the drying oven are designed as hollow shafts and provided with spraying nozzles.

An apparatus (1) for analysing surface properties, comprising a first radiation device (4) which emits radiation directly onto a surface (9) to be analyzed, a first illumination device (6, 7) for indirectly illuminating the surface (9) to be analyzed, a first radiation detector device (8) which receives at least part of the radiation thrown back from the surface (9) to be analyzed and outputs at least one signal which is characteristic of this part of the radiation. According to the invention, a radiation scattering device (10, 11) is provided which is at least partially illuminated by the first illumination device (6, 7) and which transmits scattered radiation onto the surface (9) to be analyzed.
摘要:
Systems and techniques to generate statistical reports on transactions conducted via an electronic marketplace are based on data extracted from the transaction documents. In general, in one implementation, the technique includes receiving documents sent through an electronic marketplace, with each document including multiple data fields. Data is extracted from predetermined document data fields. The extracted data relates to a predetermined statistical category of transactions conducted through the electronic marketplace. The extracted data is stored, and a report corresponding to the predetermined statistical category is provided. The report includes an aggregation of the stored extracted data associated with the predetermined statistical category. In some implementations, a report may be generated that relates to information regarding global spending according to the buyer, seller, time period, product type, contract, and/or other parameters.
