Patent CA-2258563-A1 (CA)
Inventor: SHI YAHUA
IPC: B01J27/132
Filed: 1997-06-27
Abstract: The present invention discloses a hydrofining catalyst. The catalyst has the following composition based on the total weight of the entire catalyst composition: 1-5 % (wt.) nickel oxide, 12-35 % (wt.) tungsten oxide, 1-9 % (wt.) fluorine, and the balancing amount of composite alumina. Said composite alumina is composed of one or several kinds of micropore alumina and one or several kinds of macropore alumina, wherein the weight ratio of micropore alumina to macropore alumina is 75:25 to 50:50. The term "micropore alumina" in the context means the alumina in which the volume of the pore of diameter less than 80 angstrom occupies more than 95 % of its total pore volume, while the term "macropore alumina" in the context means the alumina in which the volume of the pore of diameter 60-600 angstrom occupies more that 70 % of its total pore volume. The pore distribution mentioned above is determined by BET method of nitrogen adsorption at low temperature. This catalyst is especially suitable for the hydrofining of inferior distillates with high sulfure content and boiling range of 80-550 °C.

Filed: 1998-03-11
Abstract: In accordance with the present invention, a network management program (80) is provided that manages the communication of data packets between an intranetwork (44) and an internetwork (40). An operator of a computer connected to the intranetwork (44) inputs vital information regarding users of computers connected to the intranetwork (44), mapping information regarding computers connected to the intranetwork (44), and policies to be applied against those users and computers, using a graphical user interface (GUI 70).  The GUI (70) communicates the vital user information, mapping information and policies to a database (72) which stores and organizes the vital user information, mapping information and policies. A filter executive (76) optimizes the policies stored in the database (72) into a set of rules for each user and passes the rules to a filter engine (78). The filter engine (78) filters all outbound data packets transmitted from the intranetwork (44) to the internetwork (40) and verifies all inbound data packets from the internetwork (40) according to the rules provided by the filter executive (76). The filter executive (76) also communicates the mapping information stored in the database (72) to a naming service manager (74) which further updates the mapping information and returns the updated mapping information to the filter executive (76). Consequently, the filter executive (78) filters the data packets according to the most recent mapping information.

Title: Cdma communication system which selectively allocates bandwidth upon demand
Inventor: OZLUTURK FATIH M
IPC: H04W28/18
Filed: 1998-05-26
Abstract: A CDMA wireless digital communication system which supports all types of voice and data communications while utilizing the minimum amount of bandwidth for the particular application. The system efficiently allocates ISDN bandwidth on demand by a subscriber. Upon initialization of the subscriber unit, the system establishes a channel and generates the necessary spreading codes to support the highest capacity channel desired by the subscriber unit. Portions of the communication spectrum bandwidth are not reserved until actually required by the subscriber unit. Since the call setpup is performed at the beginning of a call from that subscriber unit, including the assignment of spreading codes, a subscriber unit can quickly gain access to the portion of the spectrum that is required to support the particular application.
