20080295986 | Method of Producing Paper and Cardboard - A method of producing paper or cardboard using a bleached cellulosic pulp, which contains hemicelluloses. According to invention a significant portion, at least 5 wt-%, preferably about 8 to 30 wt-%, of the hemicelluloses are removed from the pulp. The hemicelluloses taken from one bleached pulp can then be transferred to another resulting in two pulps with varying properties, one pulp with properties related to low hemicelluloses content in the fiber wall and the other with properties related to high hemicelluloses content on the fiber surface. | 12-04-2008 |

20120002654 | NETWORK AND NODE FOR PROVIDING A SECURE TRANSMISSION OF MOBILE APPLICATION PART MESSAGES - According to the present invention a telecommunication network with a first domain (PLMN-A) comprising at least one mobile application part protocol instance is connected to a gateway node (MSEGA) which is adapted to send and receive mobile application part messages and which is connectable to a second domain. The telecommunication network is remarkable in that the gateway node (MSEGA) is adapted to receive a mobile application part message from the first domain, to convert the received mobile application part message obtaining a secured mobile application part message, and to send the obtained message to the second domain. The gateway node (MSEGA) is further adapted to receive a secured mobile application part message from the second domain, to extract an unsecured mobile application part message from the received secured mobile application part message and to send the extracted message to the first domain. | 01-05-2012 |

20080288664 | SWITCHING APPARATUS AND METHOD FOR LINK INITIALIZATION IN A SHARED I/O ENVIRONMENT - An apparatus and method are provided that enable I/O devices to be shared among multiple operating system domains. The apparatus has a first plurality of I/O ports, a second I/O port, and link training logic. The first plurality of I/O ports is coupled to a plurality of operating system domains through a load-store fabric. Each of the first plurality of I/O ports is configured to route transactions between the plurality of operating system domains and the switching apparatus. The second I/O port is coupled to a first shared input/output endpoint. The first shared input/output endpoint is configured to request/complete the transactions for each of the plurality of operating system domains. The link training logic is coupled to the second I/O port. The link training logic initializes a link between the second I/O port and the first shared input/output endpoint to support the transactions corresponding to the each of the plurality of operating system domains. The link is initialized in a manner that is transparent to the plurality of operating system domains. | 11-20-2008 |
