Patent DE-19835643-A1 (DE)
Inventor: DILLINGER MARKUS
IPC: H04W28/22
Filed: 1998-08-06
Abstract: The invention relates to a method for allocating channels, wherein CDMA codes form the channels for communication links. The CDMA codes are represented by sequences of symbols in a tree structure and can be derived from each other. According to various allocation strategies, the position in the sequence of symbols is determined for nodes that are still available, beginning with the root of the tree structure, whenever a difference occurs in comparison with a node that is already engaged. The sum of the positions of the engaged nodes is determined and the channel with the CDMA node corresponding to the node with a pre-determinable sum, i.e. the largest or smallest sum, is allocated. As a result, it is possible to manage links with both a fixed and variable data rate in a W- CDMA mobile radio system without having to make any substantial changes in channel allocation.

Title: Safety design chuck for lathe has spring loaded drives which hold the chuck blocks when the setting tool is removed
IPC: B23B31/16
Filed: 1998-08-17
Abstract: A safety design lathe chuck has the cheeks (4) moved axially by a drive (5) with teeth profiles which grip the toothed profile under the cheeks. A setting tool (15) operates on the drive and presses it back against spring pressure (18) to release the cheeks. If the setting tool is released the springs (18) push the drive back into meshing with the cheeks. This prevents the cheeks from being hurled out of the chuck if the machine is turned on without clamping the cheeks.
