摘要:
A device for determining the wear of ink fountain films in an ink fountain has at least one ink metering element and a ductor in a printing press. The ink metering element can be moved in the direction of the doctor. A closed position of the ink metering element with an ink fountain film inserted can be determined, and that deviations from the closed position determined are registered by a sensor and the deviations registered can be supplied to a computer as a basis for determining the wear of the ink fountain film.

A method for adjusting ink zone openings in an ink fountain of a printing press uses a computer. The computer calculates a deflection of the ink fountain on the basis of an ink fountain model which contains forces that act on the ink fountain, and takes the calculated deflection of the ink fountain into consideration during the adjustment of the ink zone openings.

A method for conditioning a printing ink in a printing press includes providing an ink duct roller and a metering device, operating the ink duct roller in conjunction with the metering device for liquefying the printing ink before a start of printing, and providing a further roller for removing the printing ink from the ink duct roller. Removal of the printing ink from the ink duct roller by the further roller is held in a suppressed state, while simultaneously rotating the ink duct roller at a conditioning rotational speed, and simultaneously controlling the metering device pursuant to a conditioning profile, for only partially opening the metering device at least intermittently. A printing press for performing the method is also provided.

The present disclosure describes methods, systems, and computer program products for providing multi-level user interface theming. One computer-implemented method includes instantiating a shadow system and database schema for a new version software application in a shared database, the shadow system database schema containing aliases pointing to tables instantiated in a production database schema, instantiating a bridge database schema containing aliases pointing to each database table within the production database schema, preparing a bridge sub-system connected to the bridge database schema aliases, replicating database tables within the production database schema, for use by the bridge sub-system and adjusting the original database tables for structure and content consistent with the new version software application, deploying an upgrade sub-system and tools to complete adjustment of structure and content of the original database tables, and connecting an instantiated instance of the new version software application to adjusted database tables.

The invention relates to an arrangement for conveying concrete for the construction of multi-storey concrete buildings. The arrangement comprises a concrete-distributing mast which is height-adjustable on completed parts of the building, for example on storey floors (48′, 48″, 48′″), the mast comprising a supporting column (10), a rotary unit (12) and an arm assembly (14) preferably designed as an articulated boom, and the mast being equipped with a conveying line (16) which is guided over the height of the supporting column (10) to the arm assembly (14) and which is supplied with liquid concrete. To facilitate the handling of the concrete-distributing mast during transportation and during the climbing operation, the invention proposes that the supporting column (10) has at least one channel-shaped surface depression (36, 38) extending in the longitudinal direction of the column, in which depression can be sunk that part of the conveying line (16) which extends over the supporting column (10), and/or an elongate part of the climbing apparatus (52).
