Abstract: A method for purchasing goods, access authorizations or authorizations for using a service from a plurality of offered goods, access authorizations or authorizations for using a service. A defined spatial region is subdivided into defined subregions assigned, in each case, to a purchasable good, access authorization or authorization for using a service. A good, an access authorization or an authorization for using a service from a plurality of offered goods, access authorizations or authorizations for using a service is purchased, and a user registered in advance for carrying out the method on the basis of biometric features and/or on the basis of features, which may be assigned to the user uniquely, or an item registered in advance for carrying out the method is identified and localized in the defined subregion (1, 2, 3) assigned to the good, access authorization or authorization for using a service.

Abstract: Disclosed is an assembly for granulating polymer material, having a housing; a gas feed conduit having a rectangular cross-section and leading into the housing; a gas discharge conduit located downstream of the housing and having a rectangular cross-section; a granulating unit disposed in the housing and having a perforated plate feeding into the housing and a scraper, which comminutes the material emerging through openings of the perforated plate. In a plane running parallel to the plane of the perforated plate, the two lateral wall faces of the gas discharge conduit arranged perpendicularly to said plane enclose an angle ?2 with one another, and the two lateral wall faces of the gas feed conduit arranged perpendicularly to said plane or plane of section enclose an angle ?1, the two angles ?1 and ?2 being open towards the housing, and the angle ?1 being larger than the angle ?2.

Abstract: A method for checking access authorizations in which the entrance zone of the controlled area is divided into two zones that are arranged so that persons wishing to enter the controlled area pass through the first and then the second zone. The first zone is a registration zone having read/send devices. The second zone is an identification zone having cameras that record optical reference data of each person and transmit that and their current position to a server in real time. A real-time map containing the reference data is created based on the datasets. The read/send devices record IDs to which access authorizations and optical reference data are uniquely assigned. The IDs and assigned reference data are temporarily stored in an optical reference list which is compared in real time with the datasets of the real-time map.

Abstract: The linear bearing (3) comprises a plurality of concentrically arranged springs (2), each spring (2) being designed as a plate spring with a fixing part (2a) and a bore (2c) arranged in the center (Z). Each spring (2) also has a spring arm (2b) which emerges from the fixing part (2a) and ends in an end section (2g). The end section (2g) has the bore (2c), and the bore (2c) is concentric to the fixing part (2a). Each spring (2) has a direction of movement (B) which runs perpendicular to the fixing part (2a), and the springs (2) are arranged one behind the other in the direction of movement (B). The spring arm (2b) has a spring arm section (2ba) which runs concentrically with the bore (2c) and which extends along an angular range (?) between 100° and 270°, preferably along an angular range (?) between 180° and 300°.

Abstract: For recording and erasure of data on a reversibly writable thermal recording material (5) with a thermal print head (2), the heating elements (8) of the thermal print head for recording are subjected to an energy pulse (W) which causes the recording material to be heated to a temperature (T1) at which it assumes a colored and/or opaque state. For erasure subsequent to the recording pulse (W), the heating elements (8) are subjected to an energy pulse train (E1).
