Abstract: An authorization system (10) includes a reader (1) for a reader-card interaction (92) with a card (2), and a logic module configured to assign the reader (1) and the card (2) to each other and to make operable the reader-card interaction (92) based on authorization data comprising reader data and card data. The logic module is further configured to read via a non-contact interface (12.1) device data from an authorization storage device (5) and to assign the reader (1) to the card (2) based on the device data for making operable the reader-card interaction (92). The authorization storage device (5) is arranged spaced apart from the non-contact interface (12.1) at an essentially fixed distance (9), for example during the reader-device interaction (95). Using the device data makes it possible to enable efficiently the reader-card interaction (92) in case the reader data does not match the card data, for example.

Abstract: A refrigerant dryer, in particular a compressed air refrigerant dryer, is provided for drying a gaseous fluid while cooling the gaseous fluid using a refrigerant. The dryer includes a pressure fluid-refrigerant agent-heat exchanger (30) in which a cooling of the gaseous fluid takes place directly or indirectly by a refrigerant conveyed in a primary loop (16), one or more refrigerant compressor/compressors (24) for operating the primary loop, and a cold accumulator (13) with an accumulator-side heat exchanger (20) which couples an accumulator discharge fluid to a cold accumulator medium (14). The pressure fluid-refrigerant agent-heat exchanger (30) and the cold accumulator (13) are fluidically connected or can be brought into fluidic connection via a discharge loop (15) for an accumulator discharge fluid.

Abstract: In a rotary brush screen at an overflow sill of a rainwater relief system, comprising screen bars extending transverse to the overflow sill and strippers engaging in the screen bars in a comb-like manner, the strippers are put into a curvilinearly extending, circling movement via a crank drive in accordance with the invention by means of an actuating lever in cooperation with a stationary support bearing, due to which circling movement the strippers are guided from above into the spaces between the screen bars and out again at the bottom of the overflow sill. The risk of the discharge of solids into the waters as a result of a mechanical influence on the solids during the stripping operation is reduced thereby and the operational safety is increased.

Abstract: A method is provided for applying a cover layer (9) to a net structure (4) to be used for medical purposes, in particular a thrombosis filter. The net structure (4) is applied to a planar substrate (1) that covers openings (5) of the net structure on one side, wherein the openings (5) across the uncovered side are filled with a sacrificial material (7), in particular copper. The net structure (4) is lifted from the substrate (1). A cover layer (9) is deposited on the surface previously covered by the substrate, and the sacrificial material (7) is removed.

Abstract: For operation of contact-less identification media in a system with contact applications for contact cards, an initialized converter module is connected in series as a read/write station. This converter module, on the one hand, executes a contact-less communication with initialized contact-less identification media and, on the other hand, a contact communication at a contact card interface to a host computer or to an application computer for the communication with a contact application of the system and the converter module translates the contact-less communication with respect to communication rules and information into a contact communication with contact information and vice versa and the initialization of the converter module is defined in a hierarchic authorization system. This makes possible a particularly simple and efficient introduction of contact-less identification media into existing contact card systems and—installations.
