Title: Method and apparatus for treating salt streams
Inventor: STENMARK LARS BERTIL
IPC: A62D101/22
Filed: 1999-06-09
Abstract: A method for avoiding the precipitation of salts from a salt containing water stream prior to the stream reaching a supercritical water reactor is presented. The salt containing water stream is preferably kept at temperatures below supercritical conditions as the stream is transferred to the reactor. After the salt stream reaches the reactor the temperature of the salt stream is preferably raised to the appropriate temperature by mixing the salt stream, within the reactor, with a second stream that has been heated above the supercritical temperature of water. Alternatively, a method for preventing the clogging of the conduits upstream from the reactor may involve the mixing of two subcritical waste streams. One stream may include salts, the other preferably includes oxidizable material. The heat produced by the reaction of the oxidizable materials within the reactor preferably allows the mixture to remain at supercritical conditions for a time sufficient to oxidize substantially all of the oxidizable material.

IPC: G06F17/30
Filed: 1999-02-18
Abstract: An apparatus, program product, and method utilize a multi-target link to selectively access data located at one or more of a plurality of storage locations associated with the link. Thus, when a user (33) activates a particular multi-target link, a request may be forwarded to different storage locations in different circumstances to optimize utilization of the link, rather than the request being forwarded to the same single storage location as occurs with conventional hypertext links and bookmarks. A multi-target link may be implemented as a hypertext link defined by a hypertext link definition embedded in a hypertext document, or as a bookmark (42) for use in a custom bookmark list for a user. Moreover, various types of data, including hypertext documents, files, and the like, may be accessed from one or more of the storage locations for a multi-target link.

Title: Transmitter and receiver
Inventor: KINOMURA MASAHIRO
IPC: H04B1/18
Filed: 2000-03-16
Abstract: When a load of an antenna changes instantaneously, a cellular phone detects the load change in real time and compensates for it. The characteristic curves of power efficiency and gain of a power amplifier are drawn together on a Smith chart beforehead. The range of the operating points of the amplifier is estimated on the Smith chart from the results of measurements of the current and gain of the amplifier. The direction and level of the change in the input impedance of the amplifier is determined using impedance information contained in the Smith chart. The change is compensated for by controlling a variable-load circuit.

Title: Optimal connection set up between terminals in two networks
Inventor: HUNDSCHEIDT FRANK
IPC: H04W76/10
Filed: 1999-07-15
Abstract: The invention relates to a method and a communication system (SYS) for setting up connections from a first terminal (TE) of a first communication network (TCP/IP) to a second terminal (MS) of a second communication network (PLMN). A specific access server (AS) is selected on the basis of the location (LA) of the second terminal (MS) and/or on the basis of call processing related features (CPC) necessary for handling the call in the first and/or second communication network (TCP/IP, PLMN). Thus, always the optimal access server (AS), e.g. nearest to the second terminal (MS) can be selected, together with the appropriate functionalities needed for supporting the call in the networks. The invention is particularly advantageous if the first communication network (TCP/IP) is a packet switched network and the second communication network is a circuit switched network, since in this case the advantages of a packet switching can be maintained as much as possible and the circuit switched call is only needed over the shortest possible distance to the switching means (MSC/VLR) of the second communication network (PLMN). Thus, the resources of both networks are used optimally.

Title: Method of producing metal composites which can be processed at high temperatures
Inventor: HARDWICK ROY
IPC: B23K20/227
Filed: 1999-10-22
Abstract: A method whereby a composite clad metal ingot can be produced for onward processing at higher temperatures which are sufficient to allow the properties of the substrate material to be adequately controlled to meet specific requirements. These higher temperatures are required to avoid the undue levels of work hardening which occurs at the lower temperatures previously employed because of the need to avoid the formation of deleterious intermetallics at the bonded clad substrate interface. Such intermetallics are formed at temperatures above approximately 850 °C and should they be present, will weaken or destroy the bond. The ingot, consisting of a steel or stainless steel substrate which is clad with a corrosion resistant metal, preferably of titanium, zirconium or their alloys, and containing an interlayer of high melting point metal of tantalum, niobium (columbium) or their alloys, is processed at temperatures above 900 °C. The tantalum or niobium interlayer prevents the formation of the deleterious brittle intermetallics which would otherwise be formed at these temperatures.  Consequently, these higher temperatures can be used to control the steel properties by the conventional and prescribed methods of the art and without regard to the effects that they would otherwise have upon the bond.

Title: Computer-based product formulation
Inventor: HOOK JOHN WILLIAM III
IPC: C09D7/80
Filed: 2001-05-17
Abstract: A computer implemented method of formulating a product (e.g., a chemical product) includes receiving a product formulation script that guides the formulation of a product from a number of different components. The script can, e.g., set forth required and optional components and groups of related alternative components. To provide for such guidance, the script includes (i) a component selection option identifying sets of formulation components, (ii) at least one constraint to identify a numeric range associated with a property of one of the formulation components, and (iii) a target constraint. The product formulation script is processed to determine a collection of formulation components that can be used to produce the product such that one or more properties of the product meet associated target constraint(s). Processing of the script also includes selecting from among optional formulation components.  This selection can be performed by determining sets of formulation components to be used in formulating the product and determining a permitted range associated with the formulation components.
