Title: Method and equipment for drying a pulp web using hot air of different temperatures
Inventor: LUUKKANEN MATTI NESTORI
IPC: D21F5/18
Filed: 2001-11-28
Abstract: The invention relates to a method for drying a fibre-based pulp web (2), and to a drying box (1) used in the method. According to the invention, the drying box (1) contains drying zones (9a-9e), to each one of which hot drying air can be blown independently so that the web can be dried in the various zones at different temperatures. The temperature of the first zone (9a) can thus be lower than that of one or more subsequent zones (9b-9e) to prevent the water in the incoming wet web from boiling. The last zone in the drying box (1) can be a separate cooling zone (11), wherin the web is cooled by indoor air from outside the box. The temperatures can be adjusted by adjusting, with the aid of valves (8), the pressure of the steam, which heats the drying air that is fed into the various ones (9a-9e), on the basis of the temperatures measured by the sensors (23) for the various zones and of the basis weight and moisture measurements carried out on the web (2) that goes into the box (1) and comes out of the box.

Patent CA-2425850-A1 (CA)
Inventor: SNYDER JAMES D
IPC: G06F17/30
Filed: 2003-04-17
Abstract: Processing of source documents to generate data for indexing, and of queries to generate data for searching, is done in accordance with retrieved tokenization rules and, if desired, retrieved normalization rules. Tokenization rules are used to define exactly what characters (letters, numbers, punctuation characters, etc.) and exactly what patterns of those characters (one or more contiguous characters, every individual character, etc.) comprise indexable and searchable units of data. Normalization rules are used to (potentially) modify the tokens created by the tokenizer in indexing and/or searching operations. Normalization accounts for things such as case- insensitive searching and language-specific nuances in which document authors can use accepted variations in the spelling of words. Query processing must employ the same tokenization and normalization rules as source processing in order for queries to accurately search the databases, and must also employ another set of concordable characters for use in the query language. This set of "reserved" characters includes characters for wildcard searching, quoted strings, field- qualitied searching, range searching and so forth.
Patent CA-2427209-A1 (CA)
Inventor: ZUZARTE CALISTO P
IPC: G06F16/2453
Filed: 2003-04-30
Abstract: For an information retrieval system, a query rewrite optimization method for eliminating condition predicates of conditional expressions defining the values of a column that is referenced in the predicate of an SQL query on a view. The method evaluates the query t o identify a view and a predicate referencing a column of the view. The column has values selected by a conditional expression having condition predicates defining respective mutually exclusive ranges of values. The predicate defines a first range of values. A determination is made as to whether one of the condition predicates defines a mutually exclusive range of values that includes the first range of values. And, in response, the query is rewritten to eliminate the condition predicates other than the one condition predicate. The predicate is thus applied directly to the base tables without evaluating the conditional expression.

Title: Assessing blood brain barrier dynamics or identifying or measuring selected substances or toxins in a subject by analyzing raman spectrum signals of selected regions in the eye
Inventor: BORCHERT MARK S
IPC: A61B5/00
Filed: 2002-01-09
Abstract: A non-invasive method for analyzing the blood-brain barrier includes obtaining a Raman spectrum of a selected portion of the eye and monitoring the Raman spectrum to ascertain a change to the dynamics of the blood brain barrier.  Also, non-invasive methods for determining the brain or blood level of an analyte of interest, such as glucose, drugs, alcohol, poisons, and the like, comprises: generating an excitation laser beam (e.g., at a wavelength of 600 to 900 nanometers); focusing the excitation laser beam into the anterior chamber of an eye of the subject so that aqueous humor, vitreous humor, or one or more conjunctiva vessels in the eye is illuminated; detecting (preferably confocally detecting) a Raman spectrum from the illuminated portion of the eye; and then determining the blood level or brain level (intracranial or cerebral spinal fluid level) of an analyte of interest for the subject from the Raman spectrum. In certain embodiments, the detecting step may be followed by the step of subtracting a confounding fluorescence spectrum from the Raman spectrum to produce a difference spectrum; and determining the blood level and/or brain level of the analyte of interest for the subject from that difference spectrum, preferably using linear or nonlinear multivariate analysis such as partial least squares analysis. Apparatus for carrying out the foregoing methods are also disclosed.
