Patent MX-PA00009761-A (MX)
Title: Methods for enhancing the acid sites of fcc catalysts.
Inventor: PAVEL STEPHEN K
IPC: B01J23/94
Filed: 1999-04-05
Abstract: The present invention discloses aqueous methods for enhancing the acid sites of fluid catalytic cracking (FCC) catalysts. The methods comprise the steps of contacting an FCC catalyst, either spent or fresh, with an aqueous solution comprising water, an inorganic acid substantially free of chloride and aluminum. The acid is preferably sulfurous or sulfuric acid. The aluminum is provided by an aluminum source selected from the group consisting of the alumina trihydrates and aluminum oxide. Chloride contamination of the aluminum source should be minimal, preferably less than about 1000 ppm chloride, more preferably less than about 200 ppm chloride. The pH of the aqueous solution is adjusted to about 3-12 by the addition of a sufficient quantity of ammonium hydroxide. The FCC catalyst is added to this solution, preferably with stirring, in a weight ratio of about 1 part catalyst to about 1-10 parts water to prepare an aqueous slurry. Upon stabilization of the pH of the aqueous slurry, enhancement of the acid sites of the catalyst is achieved and the catalyst may be separated from the slurry and, if desired, washed. This simple, aqueous process reduces the level of many metal poisons on the FCC catalyst and produces a catalyst having an enhanced number of acid reaction sites.

Title: Removal of oil and chloride from oil contaminated material.
Inventor: BRIAN G ROBERTS
IPC: C09K3/32
Filed: 1999-12-13
Abstract: A method for chemically removing hydrocarbons from oil contaminated material is described. The method comprises contacting the material containing the oil with a combination of surfactants in an oil carrier similar to or identical to the oil to be removed. This process avoids the use of water. Therefore the process does not compromise the quality of the oil by having water as a contaminant and thus eliminating the possibility of oil contaminated water getting into the environment. In certain examples, when the process is used to remove oil from land based well bore cuttings, the processed well bore cuttings contain high levels of chlorides, which is an environmental problem. In such examples the method also includes contacting the well bore cuttings with a solution of dioctyl sodium sulfosuccinate in water to reduce the chloride concentration. An apparatus designed for this purpose is also described.

Title: Method and system for controlling access to a telecommunication or internet system.
Inventor: HILL VINCENT
IPC: G06Q30/04
Filed: 2001-01-27
Abstract: A method and system for controlling telecommunications or computer network, e.g. Internet, access. The system includes a gateway server (50) connected to the network (60) communicating with a computer terminal (51). Removable media at the computer terminal (51) stores a gateway server address, a profile identifier, and programming directing the terminal operating system to access the gateway server and transmit the profile identifier. The gateway server (50) includes a database of profiles correlated to profile identifiers, each profile having an access criterion, and programming directing the access of a profile upon receipt of a profile identifier. The programming determines whether the access criterion is satisfied and allows or denies network access. Optionally, the access criterion is an access period. Additionally, the account billing information is optionally examined to determine whether the user has a time or credit balance remaining. Programming may monitor the access to disconnect the computer terminal (51) from the network (60) if the access criterion is not satisfied. The method begins with identifying the user or computer terminal (51) requesting access to the network (60). A profile for the requestor, including an access criterion, is accessed from a database at a gateway server (50). The gateway server (50) determines whether the access criterion is met and access is allowed or denied.

Title: Drillhole blasting.
Inventor: COLLINSWORTH STEPHEN MITCHELL
IPC: F42D/
Filed: 2001-11-19
Abstract: A blasting arrangement (10) includes drillholes (30) in a rock mass (20). Blind ends (32) are drilled to a desired level and, if necessary, are adjusted as shown at (62) to said level. Each hole (30) is plugged by means of a plug (42), which is protected by non flammable buffer material (44), at a level (40) spaced from the end (32). Explosive (50) is charged above the level (40) and the hole is tamped, shown at (60). The holes are detonated desirably by detonators (52), forcing the plugs (42) downwardly and compressing air in chambers (34) above the ends (32). The weakest part of each hole, around the end (32), is split causing a three dimensional zone of weakness at the level of the ends (32). Air forced into the zone of weakness causes a fracture zone (70) at that level, inhibiting propagation of blasting shock waves and protecting the material underneath the level of the ends (32).

Title: Method and system for forward link beam forming in wireless communications.
Inventor: BRUCE A JUDSON
IPC: H04B7/06
Filed: 2002-01-17
Abstract: According to one embodiment, an antenna beam pattern is ised to send a communication signal to a user. For example, the antenna beam pattern can be formed using adaptive antenna array technology on the forward link of a wireless communication system. A control signal from the user is used to determine a statistic. For example, the control can be a power control bit sent by the user on the return link. The statistic can be an average of the power control bit values over a specific time interval. The statistic is used to narrow the antenna beam pattern and direct it toward the user. For example, a dithering algorithm can be used to optimize the antenna beam pattern. After a call is completed, an optimized antenna beam pattern specific to each user can be stored for the next call to make the optimizing process faster and more efficient.
