Patent CA-2147851-A1 (CA)
Inventor: HAYASHI YUUICHIROU
IPC: E04B1/76
Filed: 1994-08-23
Abstract: This invention relates to a new method for constructing of a building composed of combination of frame members, at an architectural spot, and aims to not only improve the efficiency in construction, but also to realize high insulation and airtightness in the building. Airtight lubricant is smeared on a frame member to be connected to a established frame member at its fitting end. The frame member is connected to the established frame member by dropping or heading, for example, reducing frictional resistance during fitting or connecting process due to the existence of the airtight lubricant. The process realizes high insulation and airtightness in the structure at the joint portion due to the existence of the airtight lubricant.

Title: Determination of an individual's inflammation index from whole blood fibrinogen and hematocrit or hemoglobin measurements
Inventor: BULL BRIAN S
IPC: G01N33/86
Filed: 1995-05-17
Abstract: Useful information about a subject's level of systemic inflammation is obtained by quantitatively measuring the amount of fibrinogen and the hematocrit and or hemoglobin in the subject's whole blood. The fibrinogen measurement, when combined with an hematocrit or hemoglobin measurement, provides a systemic Inflammation Index value for the donor. The method is not affected by blood variables which are not related to the presence of inflammation, which blood variables areknown to invalidate an erythrocyte sedimentation rate, which is the most frequently used blood test for detecting systemic inflammation in humans.

Title: Process for the recovery of molybdenum from impure calcium molybdate resulting from the treatment of uraniferous ores
Inventor: BRASSIER CECILE
IPC: C01G39/00
Filed: 1995-07-18
Abstract: The invention relates to a process for the recovery of the molybdenum present in impure calcium molybdate result-ing from the treatment of uraniferous ores.     According to this process (in 40) the calcium molyb-date is dissolved in an aqueous solution containing at least 2 moles/? of H2SO4 and then the molybdenum is ex-tracted (in 21) in an organic solvent comprising a dialkyl phosphoric acid such as di-(2-ethylhexyl)-phosphoric acid.     After extraction, it is possible to wash the solvent (in 23) using an aqueous sulphuric acid solution and then recover the molybdenum extracted in the reextraction solvent in an ammoniacal solution.     The choice of a dissolving solution having a H2SO4 concentration of at least 2 mole/? avoids the formation of difficultly extractable heteropolymolybdic components.

Title: Intelligent accompaniment apparatus and method
Inventor: PAULSON JOHN W
IPC: G10H1/36
Filed: 1994-05-19
Abstract: A system for interpreting the requests and performance of an instrumental soloist, stated in the parlance of the musician and within the context of a specific published edition of music the soloist is using, to control the performance of a digitized musical accompaniment Sound events and their associated attributes are extracted from the soloist performance and are numerically encoded. The pitch, duration and event type of the encoded sound events are then compared to a desired sequence of the performance score to determine if a match exists between the soloist performance and the performance score. If a match exists between the soloist performance and the performance score, the system instructs a music synthesizer module to provide an audible accompaniment for the soloist. The system can provide an accompaniment for a selectable amount of time event if the soloist intentionally or unintentionally departs from the score.

Title: Mattress and furniture insulator pad
Inventor: RUCKER JOHN R
IPC: A47C21/06
Filed: 1996-03-04
Abstract: The present invention relates to mattress or furniture insulator pads that are placed between the coil springs and the cushioning material in mattresses or furniture, such as chair seats. Such insulator pads prevent the springs from piercing the furniture cushion and provide a bridge across the springs to more evenly distribute weight over the springs. The insulator pads according to the invention have three layers formed by sandwiching polyurethane foam between stiffening layers, preferably formed from polypropylene openmesh netting. Most preferably, a five layer insulator pad has the polyurethane foam sandwiched between stiffening layers and also has thin outer layers of polyurethane foam, applied adjacent to the stiffening layers, forming the top and bottom surfaces of the pad. Such thin outer layer foam sheets provide friction characteristics that retard relative movement between the cushion and the springs. The invention further relates to a method of making a laminated product, such as an insulator pad comprised of foam and stiffening layers held together with adhesive, in which a thin protective barrier foam sheet is placed between the surface of the compression roller and the sheets to be laminated together. The thin protective barrier foam sheet may or may not form the outer layer of the laminate product and prevents adhesive and foam material from contaminating the surface of the roller.

Patent CA-2178264-A1 (CA)
Title: Database management system with improved indexed accessing
Inventor: LESLIE HARRY A
IPC: G06F17/30
Filed: 1996-06-05
Abstract: A database management system (DBMS) provided with a multi-dimensional improved indexed accessing capability using keyed index searching.   Individual search keys are constructed from general expression statements created in the DBMS compiler from search queries supplied to the DBMS.  Each key column represents another dimension, and both ranges and IN lists can be specified in the search query and used as the predicate values in multiple columns.  Missing predicate values in the search query are interpreted as a specification of the minimum and maximum values for the associated search key column.  During compile time, the DBMS compiler produces general expressions to be used by the DBMS executor during run time to create the search keys.  The DBMS compiler evaluates search queries by associating predicates with clusters and disjunct numbers assigned to each individual disjunct in the search query expression.  The DBMS executor uses the general expression from the compiler and eliminates any conflicts among same column predicates, removes redundancies in predicate values and disjuncts and reduces the number of records to be accessed to the minimum required to complete the search query.  The individual search keys are generated in the same order as the index to which the search pertains (i.e., increasing or decreasing order).
