Compositions, methods and assays relating to the diagnosis and detection of the presence of the positive-stranded RNA virus, or antibodies to the positivestranded RNA virus, in a sample. Compositions and methods for the induction of immune responses in, and vaccination of, an animal. Combination of the unprocessed core region with a non-structural protein (such as an NS5 or an unprocessed NS3-NS4 fusion from HCV).

Title: Composition analysis
Inventor: GOODACRE ROYSTON
IPC: G06N3/04
Filed: 1996-06-10
Abstract: A method and apparatus for analysing a sample, in which a neural network is trained to correct for measurement drift of a given analytical instrument (e.g. a mass spectrometer). The training is carried out using first and second sets of data obtained by the instrument from samples of known compositions at initial and subsequent instants of time, respectively. The trained neural network is used to transform data, obtained by the instrument from a sample of unknown composition at said subsequent instant of time, to an estimate of the data which would have been obtained by the instrument from that sample at the initial instant of time. The transformed data is then analysed to analyse the sample of unknown composition.

Title: Ferrous material recovery system
Inventor: KELLER SAMUEL A
IPC: B02C17/04
Filed: 1996-10-17
Abstract: A system for recovering ferrous metal components from waste materials includes a first magnetic separator (14) for magnetically separating ferrous metal components from waste material and an impacting device (16) for dislodging residual waste material from the surface of ferrous metal components separated by the first magnetic separator (14). The system may also include a second magnetic separator (54) following the impacting device (16), a water washing system (58) for cleaning ferrous metal components retained by the second magnetic separator (54), a ferrous metal collection station (60) and a waste material collection station (64).

Title: Network and switching node in which resource can be reserved
Inventor: IKEDA NAOYA
IPC: H04L12/56
Filed: 1998-04-29
Abstract: A user terminal sends a resource reservation request message in which time information indicative of time to perform a communication is designated to a switching node to which the self user terminal is linked.  The switching node manages a reservation state of each of resources which can be used by the self switching node among resources of a network together with time information indicative of time when a communication using the resource is performed.  When the resource reservation request message is received, an unreserved resource is obtained at a time indicated by the time information designated in the resource reservation request message, the obtained resource is reserved, and a resource reservation result notice message indicative of the reservation result is returned to the user terminal.  A resource management server is also provided so as to reserve a network resource with a simple operation.  The reservation can be performed in consideration of priority and cost of a communication.  Reservation information can be always recognized by a client.  When resource reservation is failed, an alternative plan is automatically calculated and presented.
