A task-like user interface is provided for Web-based applications. Preferred embodiments enable users to initiate multiple instances of tasks within a single Web application, where independent state information is retained for each instance. Each user-initiated task also has a prescribed life cycle with a definite start and end. Resources allocated to perform various activities can therefore be released when the activity ends. Optionally, contextual information can be passed to a task upon invocation. Support for persisting a currently-viewable work unit as a user-selectable favorite may optionally be provided.

In order to be able to control the creation of a user channel connection in a communication system using wireless communication between at least one mobile part and one wired part in such a way that a user channel connection is established more quickly upon a connection request indicated by the mobile part or the wired part for the purpose of transmitting user data and, at the same time, due to market requirements, no synchronization pulses are sent by the wired part in the idle state, an initiating device of the communication system (for example, for an incoming call: base station; for an outgoing call: mobile part) sends, from an asynchronous idle state, synchronization pulses (SB) to all available physical resources. Due to the plurality of the sent, available synchronization pulses (SB), rapid synchronization is ensured because the probability is sufficiently increased thereby that a pulse will fall in the search window of a receiver.

The invention relates to a loading mechanism in a tape deck of a magnetic-tape-cassette apparatus, for moving a magnetic-tape cassette from an eject position of the loading mechanism into a play position of the loading mechanism. The mechanism comprises a cassette holder for holding the magnetic-tape cassette and a first lift plate, by means of which the cassette holder is movable between an intermediate position of the loading mechanism and the play position of the loading mechanism substantially in a vertical loading direction. The first lift plate and the cassette holder are movable from the eject position into the intermediate position in a horizontal loading direction, and a lift element is arranged on a frame so as to be rotatable and so as to be movable in the horizontal loading direction. The cassette holder, the lift element and the first lift plate are movable from the intermediate position into the eject position and vice versa in the horizontal loading direction. When the first lift plate is moved in the horizontal loading direction it exerts a force on the cassette holder and the lift element in such a manner that the cassette holder is moved substantially in the vertical loading direction, during which movement the lift element performs a rotary movement.
