Title: Internet server access control and monitoring system
Inventor: PAYNE ANDREW C
IPC: G06F21/41
Filed: 1996-06-03
Abstract: This invention relates to methods for controlling and monitoring access to network servers. In particular, the process described in the invention includes client-server sessions over the Internet involving hypertext files. In the hypertext environment, a client views a document transmitted by a content server with a standard program known as the browser. Each hypertext document or page contains links to other hypertext pages which the user may select to traverse. When the user selects a link that is directed to an access-controlled file, the server subjects the request to a secondary server which determines whether the client has an authorization or valid account. Upon such verification, the user is provided with a session identification which allows the user to access to the requested file as well as any other files within the present protection domain.

Title: Method and system for multilingual online purchasing
Inventor: DE LA MOTTE ALAIN L
IPC: G06Q10/00
Filed: 1996-11-08
Abstract: A system for facilitating, selecting, ordering, and purchasing of products includes a purchase-facilitating, software-implemented computer system located near a buyer, a trade-facilitating hub, and one or more vendors. Using the purchase-facilitating program, the buyer enters business and trade information and also enters information regarding the various products (available from vendors) that the buyer desires to purchase (200). After buyer-information and product-selection information have been entered in the purchase-facilitating program, that information is combined into a composite document which is sent (preferably via facsimile or internet) (228) to the trade-facilitating hub. At the hub, the composite document is converted into multiple documents which are sent to each corresponding vendor. The hub then forwards responses from the vendors to the buyer. If the buyer, hub, and vendors use different languages, then the preferred system translates all correspondence into the appropriate language for the receiving party prior to sending.

Title: Polymer-organoclay-composites and their preparation
Inventor: ANDERSON KENNETH W
IPC: C09J167/00
Filed: 1997-12-22
Abstract: A polymer composite comprising a hydroxy-phenoxyether or polyester polymer matrix having dispersed therein layers of an inorganic material derived from a multilayered inorganic material having organophilic properties. The dispersion of the multilayered inorganic material in the polymer matrix is such that an increase in the average interlayer spacing of the layered inorganic material occurs. This increase in interlayer spacing occurs to a significant extent resulting in the formation of a nanocomposite. The polymers are preferably derived from a diglycidyl ether or ester or an epihalohydrin and a dinucleophile such as a dicarboxylic acid, a difunctional amine, a bisphenol or a sulfonamide. As the organophilic inorganic material clay minerals modified with organic ammonium compounds are used.

IPC: C01G23/00
Filed: 1998-10-19
Abstract: The present invention relates to a process for concentrating highly impure titanium ore, such as anatase, with the main purpose of obtaining a final concentrate having a chemical composition similar to that of ilmenite. The process is based on the use of the following sequence of operations for the beneficiation of titanium ores: disintegration, screening, crushing, classification, low intensity magnetic separation, attrition and slimes removal, calcinations in the presence of sodium carbonate (Na2CO3) and/or potassium carbonate (K2CO3), comminution of the calcinations to a partied size below 1 mm, leaching in alkaline medium (pH in excess of 10) followed by acid leaching, The final concentrate, which is rich in titanium and iron and has a low content of impurities, is the intermediate raw material for the process of producing titanium slag.
Patent CA-2249945-A1 (CA)
Inventor: LEHMANN RICHARD W
IPC: C02F1/74
Filed: 1998-10-09
Abstract: A process is disclosed for producing an oxidized liquid effluent containing minimal dissolved gases therein, from a subcritical wet oxidation treatment system.  The oxidation mixture exiting from the treatment system is separated into a first oxidized liquid effluent and a first gaseous phase as the mixture a first separator vessel operated at a relatively low superatmospheric pressure. Sufficient pressure is maintained in the first gaseous phase to provide the motive force for transport to further treatment or discharge. The first oxidized liquid effluent flows to a second separator vessel operated at essentially atmospheric pressure, where remaining dissolved gases separate from the first oxidized liquid effluent. The second gaseous phase is discharged and the second oxidized liquid effluent is suitable for storage or further treatment. Provision for adjusting the pH of the oxidized liquid effluent during the separation process is also disclosed.

Title: Distributed real-time communications system
Inventor: MOLLER MATTHEW DONALDSON
IPC: G10H1/00
Filed: 1997-03-27
Abstract: A method and apparatus is provided which enables users to communicate in a perceived real-time environment. In one embodiment, a number of musical parts are contributed one each from a number of client terminals. Each terminal generates and sends to a server a short sequence or sequence of sequences, for example a few bars of music. The server echoes the sequences out to each of the other clients' terminals where they are synchronised to a local clock and repeated a plurality of times, with the generated sequence being repeated at the sending client a similar number of times. The local synchronisation overcomes the problems of propagation delay between clients and server, and the repetition of sequences allows a continuous stream of data to be output at each client. A solo or non-repetitive line may be added by commencing sending the solo line to the server before the remaining lines. The solo line is buffered at each of the clients and then synchronised to the local clock. The non-solo lines arrive at the solo client after the solo data stream has commenced. However, as they are repetitive, they are synchronised by the local clock to the next sequence repeat.

Inventor: MIMURA YOSHIHIRO
IPC: G06Q30/00
Filed: 1998-10-26
Abstract: In an online shopping service when orders are sent via a computer network, mistaken operations and unauthorized operations of buttons with economic consequences are prevented without affecting the freedom of users to make button operations that are unrelated to the ordering of products.  Each set of button data includes a control command and execution condition information.  The non-volatile memory in a reproduction apparatus stores execution permission judging information that is used when judging whether the execution of control commands is permitted.  When a button operation has been made, the control unit refers to the execution condition information of the selected button and the execution permission judging information, and then judges whether the execution of the control command corresponding to the button selected in the button operation is permitted.
