A process for preparing a polyamide by reacting at least one aminonitrile with water comprises: (1) reacting at least one aminonitrile with water at a temperature from 100 to 360° C. and a pressure from 0.1 to 35×106 Pa to obtain a reaction mixture, (2) further reacting the reaction mixture at a temperature from 150 to 400° C. and a pressure which is lower than the pressure in step 1, the temperature and the pressure being selected so as to obtain a first gas phase and a first liquid or a first solid phase or a mixture of first solid and first liquid phase, and the first gas phase is separated from the first liquid or the first solid phase or from the mixture of first liquid and first solid phase, and (3) admixing the first liquid or the first solid phase or the mixture of first liquid and first solid phase with a gaseous or liquid phase comprising water at a temperature from 150 to 360° C. and a pressure from 0.1 to 30×106 Pa to obtain a product mixture.

The present invention relates to a functional screen assay for nonsense or frameshift mutations that allows genes of interest to be scanned. This assay is based on the cloning of segments of the gene of interest in-frame with a sequence coding for a marker followed by screening for the level of expression of the marker. Individuals at risk for any one of a number of genetic diseases, which are associated with such nonsense or frameshift mutations, can be quickly screened for chain-terminating mutations introduced by these nonsense and frameshift mutations. At present, scanning of many genes for mutations requires significant effort because the genes are large and most mutations are unique. Therefore, this assay offers a powerful option for the diagnosis of many genetic diseases.

Provided is a shower drain cover configured to enhance the aesthetic appeal of a shower surface having a drainage opening formed therein. It is understood that shower surfaces are typically formed from a design material, such as tile or stone. Accordingly, the shower drain cover includes a design cavity sized and configured to receive a portion of the design material such that the drain cover will more effectively blend into the design surface to enhance the overall appearance of the shower.

The invention relates to a method and device for printing a substrate. The printable substrate is moved through at least one printing mechanism in order to print a static or non-variable printing image. According to the invention, the printable substrate is moved through at least one printing device, which is coupled in-line to the printing mechanism to individualize the static pattern with at least one dynamic or variable printing image.

The aim of the invention is to simplify the attachment of RFID chips or RFID transponders to packagings. For this purpose, the RFID chips are produced as a single RFID label together with antenna elements that are functionally associated therewith. The chips or transponders can be attached to a packaging by means of corresponding devices during production of the printed material, during a subsequent treatment or finishing process of the printed material, during the preparation of the packaging, during production of the packaging or during filling of the packaging. At the time of attachment, the RFID chips can be tested and initialized. The invention allows to considerably simplify the so far complex processes required to integrate the RFID chips into different types of packaging.
摘要:
A method of printing an electronic circuit or components thereof uses a printing machine to print a conductive structure on the front printing side (back side of the sheet) of a printing substrate. The sheet is then reversed and a decorative printing motif is printed on the back side in one work step. Alternatively, the circuit or components of a circuit may be printed by having a printing machine for color printing preceded by a printing machine for printing on the back side of the printing substrate. A chip is applied to the printing substrate where the back side of the printing sheet with the printing motif is cooled to prevent any negative effect on the printing motif and/or the printing substrate.

A method for printing a substrate web in a rotary printing press is disclosed. The substrate web to be printed is conveyed through a printing form-based printing unit for static printing of the substrate web with a print image that does not vary for the print copies of a printing job, such that at least one static print page is printed in the longitudinal direction of the substrate web per revolution of the form cylinder and several static print pages are printed on the substrate web across the longitudinal direction of the substrate web. In addition to static printing, the statically printed substrate web is printed dynamically with a variable print image in the area of a printing form-free printing device of the rotary printing press such that the print format of the printing form-free printing device extends in at least some sections over at least two statically printed pages.
摘要:
Semiconductor wafers are processed so as to remove material on one or both sides by means of at least one grinding tool, with coolant supplied into a contact region between the semiconductor wafer and the at least one grinding tool, characterized in that the coolant flow rate is set as a function of a grinding tooth height of the at least one grinding tool and this coolant flow rate is reduced as the grinding tooth height decreases.
