Abstract: A catalyst for hydrocracking of heavy oils comprises iron and active carbon having an MCH conversion rate of 40-80 %, a specific surface area of 600-1000 m2/g of, a pore volume of 0.5 to 1.4 cm3/g, 2-50 nanometers' mesopore volume of not less than 60% and the average pore diameter of 3-6 nanometers, the iron being carried on the active carbon in an amount of 1 to 20 wt.% to the active carbon. The hydrocracking process by using the catalyst includes the first step of conducting hydrocracking at a temperature within the range of 360-450 °C at a hydrogen partial pressure of 2-14 MPaG and the second step of conducting hydrocracking at a temperature within the range of 400-480 °C at a hydrogen partial pressure of 2-18 MPaG, which can suppress generation of coke and remove in a high efficiency heavy metals such as Ni and V, asphaltene, residual carbon, sulfur and nitrogen from the heavy oils.

Abstract: Compositions of HBsAg particles having biologically active molecules contained in the particles, and methods of their use, e.g. in stimulating enhanced immune responses, are described. Antigenic peptides contained in HBsAg particles were found to produce a CTL response where none was elicited by the peptide alone. Encapsulation of immunostimulating molecules, such as cytokines, greatly enhanced the CTL response evoked by the HBsAg particles themselves.

Title: Chromatic dispersion compensation device
Inventor: COLBOURNE PAUL
IPC: H04B10/18
Filed: 2000-10-27
Granted: 2008-10-14
Abstract: A method and device is disclosed for dispersion compensation of an optical signal having periodic dispersion within a multi-channels system. For example interleaved optical channels often exhibit dispersion having a characteristic that is repeated in adjacent channels. By providing a periodic device in the form of a multi-cavity GT  etalon having a free-spectral range that corresponds to the channel spacing the dispersion in the interleaved signal can be lessened and practically obviated or balanced to a desired level.  Advantageously, the input and output angle of the signal can be varied to provide fine tuning. This invention provides a device and method to achieve that end.

Abstract: A method and apparatus for processing position information from satellite positioning system satellites and from cellular based communication signals. In one example of a method according to the invention, a SPS receiver receives SPS signals from at least one SPS satellite. This SPS receiver is coupled to and typically integrated with a communication system which receives and transmits messages in a cell based communication system. In this method, a message is transmitted in the cell based communication signals between a communication system and a first cell based transceiver. A time measurement which represents a time of travel of a message in the cell based communication signals between the cell based transceiver and the communication system is determined. Another time measurement which represents a time of travel of the SPS signals is also determined. A position of the SPS receiver is determined from a combination of at least the time measurement which represents the time of travel of a message in the cell based communication signals and from a time measurement which represents a time of travel of the SPS signals. The cell based communication signals are capable of communicating data messages in a two-way direction in one embodiment between the cell based transceiver and the communication system.

Title: Temporary selective national roaming at predetermined network operation conditions in a mobile radio communication system
Inventor: SALMINEN REIJO
IPC: H04Q7/36
Filed: 1999-07-29
Granted: 2009-04-14
Abstract: The invention relates to a method, an exchange, a telecommunica-tion system and a mobile station for providing a temporary selective national roaming at predetermined network operation conditions, e.g. at network overload in a mobile radio communication system. A first switching means (MSC/VLR) of a home network (HPLMN) performs a negotiation with a second switching means (MSC/VLR') of another network (VPLMN) which has free capacity to handle mobile stations (MS1-MS4) of the first network (HPLMN) which cannot be handled by said first network (HPLMN) during e.g. an overload condition occurring therein. When e.g. the overload condition occurs, a request message (RM) is first sent to the second switching means (MSC/VLR') in order to enquire whether the second network (VPLMN) has enough free ca-pacity to take over mobile stations (MS2-MS4) from the first network (HPLMN). Thus, it can be ensured that mobile stations (MS1-MS4) of the first network (HPLMN) do not cause an overload condition in the second network (VPLMN) when they have been registered in the second network (VPLMN) and receive a service therein.
