Patent CA-2344877-A1 (CA)
Title: Anionically derivatised cotton for improved comfort and care-free laundering
Inventor: BELLA OTTO
IPC: D06C7/02
Filed: 1999-09-21
Abstract: The present invention is generally directed to a process for making fabrics containing cotton fibers more aesthetically pleasing and resistant to staining by anionic dyes by derivatising the cotton so that it exhibits a permanent anionic charge. By increasing the anionic charge of the fibers, the fibers become resistant to anionic coloring agents which may undesirably come into contact with the fibers. Furthermore, the negative charges repel each other resulting in a fabric with greater loft and porosity. This results in greater smoothness, better hand, and more comfort. Besides being used to prevent the cross-staining of fabrics, the present invention can also be used to make carpet materials resistant to anionic staining agents. Alternatively, it has also been discovered that an anionic derivative can be used to catalyze permanent press resins onto fabrics containing cellulosic fibers, also resulting in anionic cotton.

Title: Method for controlling bearer properties
Inventor: AHMAVAARA KALLE
IPC: H04L12/56
Filed: 1999-11-05
Abstract: The invention concerns the control of connections in cellular telecommunication systems According to the invention, the available radio resources are controlled by allowing only certain combinations of transport formats to be used by a single user. The inventive method restricts the combinations of bearer bit rates which can be used, without strictly limiting some bearers from using the highest bit rate. This inventive approach allows flexible overall control of radio resources, while retaining the possibility of bearers to select between different bit rates.
