Abstract: A system for the automated acquisition of tickets, including a first device (client) with a radio module for wireless data transmission. Also including a vendor for wireless data transmission which is suitable for exchanging data with the client. In the event of an initialized connection, the authentication between the client's device and vendor's device is started. Following a successful authentication, the client's device is designed to transmit client related data. The client related data are then verified, and a unique ticket is generated in the event, that predefined criterions are satisfied. The issued ticket provides access to the client requested services. The method according to the invention allows for maximum convenience, and reliability in issuing tickets for travelling with transportation systems or attending an event and/or granting physical access to a service or location.

Abstract: A system for forwarding personal data, including a first device with a radio module for wireless data transmission. The system also includes a second device having a second radio module for wireless data transmission which is suitable for exchanging data with the first device. An initialization is requested by the first radio module and/or by the second radio module and is received by the other radio module for initialization of a connection between the first device and the second device. In the event of an initialized connection, the first device is designed to transmit personal data directly by means of the first radio module to the radio module of the second device. The personal data are then compared on the second device, and an indication is generated in the event that a predefined criterion is satisfied.

Abstract: Polyaspartic acid and, optionally a non-ionic surfactant, are used to treat circulating water from a paint shop.

Abstract: A method for cleaning paint carrying parts of a paint shop, especially the paint lines, is described, wherein the paint carrying parts are rinsed with a liquid containing an organic solvent. In order to obtain particularly advantageous conditions, polyaspartic acid is mixed with the rinsing liquid.

Abstract: A process for the preliminary treatment of a metallic workpiece before coating is disclosed. The surface to be coated is cleaned with a solution containing a degreasing agent and coated with a corrosion-inhibiting layer. In order to obtain particularly advantageous conditions, the invention proposes that the surface of a workpiece to be coated be treated with a solution of polyaspartic acid to apply a corrosion-resistant coating.
