Abstract: A method is provided for installing a security-relevant portion of an application made available by an application provider in a security element of a terminal. The terminal requests the application from the application provider and receives the application. Subsequently, the received security-relevant portion of the application is transmitted to a trustworthy instance administrating the security element. The trustworthy instance subsequently installs the security-relevant portion of the application in the security element.

Abstract: A belt retractor including a force limiter comprises a belt reel which is rotatably supported in a frame as well as a blocking unit counteracting a rotation of the belt reel and a force limiter between the belt reel and the blocking unit which permits a limited torsion of the belt reel against the blocking unit under load. The force limiter includes a damping element consisting of a cross-linked polymer which is sheared under load.

Abstract: A machining apparatus has a machine frame having a vertical front wall and a pair of vertical side walls extending generally perpendicularly rearwardly from the front wall and a cross slide vertically displaceable on the front wall. A first holder is horizontally displaceable on the cross slide, and respective carriages horizontally displaceable generally perpendicular to the front wall on the side walls carry a mount between and pivotal in the carriages about a horizontal axis generally parallel to the front wall. A second holder is carried on the mount. One of the holders is adapted to hold and rotate a workpiece and the other of the holders to hold a tool. A drive is connected to both of the carriages for synchronously displacing same and thereby aligning the workpiece in the one holder with the tool in the other holder.
