Title: Estimation method and system for financial securities trading
Inventor: PASKOV SPASSIMIR
IPC: G06Q40/00
Filed: 1995-08-15
Abstract: In setting the initial offering price of a financial instrument for purposes of securities trading, or in later revaluation as economic factors, such as interest rates, may change, an estimate of the value of the instrument may be represented as a multi-dimensional integral. For evaluation of the integral, numerical integration is preferred with the integrand being sampled at deterministic points having a low-discrepancy property. The technique produces approximate values at significant computational savings and with greater reliability as compared with the Monte-Carlo technique (11).

Title: Methods and materials for producing pathogen-resistant plants
Inventor: ABOUZID AHMED
IPC: C12N15/82
Filed: 1996-08-12
Abstract: This invention comprises a mutant plant virus gene which confers resistance on tobacco and tomato plants against tobacco mosaic tobamovirus and tomato mottle geminivirus infections and infection by other related geminiviruses. A gene was initially isolated from the known BC1 gene, between nucleotides 1278 and 2311 of the B component of tomato mottle geminivirus. Upon subcloning of this DNA fragment into an appropriate expression vector and transformation of the gene into tobacco plants, a truncated gene product was produced which confers resistance against viral infection to the recombinant plant in which it is expressed.

IPC: B21D51/26
Filed: 1996-09-17
Abstract: A method of manufacturing a metallic can body (24) that is shaped distinctively in order to enhance its visual presentation to consumers includes, in one embodiment, steps of providing a can body blank (10) that has a sidewall that is of a substantially constant diameter; providing a mold unit (38) that has at least one mold wall (46) that defines a mold cavity conforming a desired final shape of the can body (24); positioning the can body blank (10) within the mold cavity (46); and supplying a pressurized fluid into the mold cavity so that the can body blank (10) is forced by pressure against the mold wall (46), causing the can body blank (10) to assume the desired final shape of the can body (24).

Title: Bypass system and method for regenerative thermal oxidizers
Inventor: BAYER CRAIG E
IPC: B01D53/72
Filed: 1997-05-06
Abstract: A regenerative thermal oxidizer (10) in which contaminated air is first passed through a hot heat exchange bed and into a communicating high temperature oxidation (combustion) chamber (3), and then through a relatively cool second heat exchange bed. The apparatus includes a number of internally insulated, ceramic filled heat recovery columns (2A, 2B) topped by an internally insulated combustion chamber (3). From the combustion chamber (3), the air flows vertically downward through another column containing heat exchange media, thereby storing heat in the media for use in a subsequent inlet cycle when the flow control valves reverse. Temperature is sensed within the bed of heat exchange media in order to monitor the temperature profile and control a bypass of hot combustion gases should the temperature exceed a predetermined level.

Patent CA-2262957-A1 (CA)
Inventor: PAO YOH-HAN
IPC: G06N3/12
Filed: 1997-07-29
Abstract: A parallel, distributed processing system is provided for solving NP-hard problems, and the like, efficiently, quickly and accurately. The system employs parallel processors which are iteratively and intelligently allocated for a series of generations of child solutions from selected, previous generation or parent solutions. The system employs multiple levels of competition for generating a next level of possible solutions and for reallocating processor resources to the most promising regions for finding a best solution to the task. This includes both inter-family competition, as well as intra-family competition. System temperature data are set and gradually decreased with each succeeding generation. A degree of randomness is entered into the solution generation. The hierarchical and iterative process, incorporating randomness and a decreasing temperature provides for the guided evolutionary simulated annealing solution generation.

Title: Vibration isolation insert for aircraft floor panels and the like
Inventor: HAIN HARRY L
IPC: F16B5/02
Filed: 1997-09-04
Abstract: An insert (20) used to connect aircraft floor panels (11), and the like, to supporting structure (13) includes features which function to isolate the supported panel (11) from vibrations in the supporting structure (13). The isolation of the panels (11) leads to reductions in SIL (Speech Interference Level) noise within aircraft cabins. The insert (20) consists of internal and external rigid components separated by a contoured elastomeric component (32). The elastomeric component (32) is preloaded when installed via a fastener (15) extending through the inner rigid component (42, 42') and attaching to the supporting structure (13). The outer (22, 22') and inner (42, 42') rigid components are sized such that the inner rigid component (42, 42') will not pass through the outer rigid component (22, 22'), thus providing a safetied installation of the panel (11). The elastomeric component (32) extends below the bottom of the outer rigid component (22, 22') and provides soft snubbing against the supporting structure during loading of the panels (11). This allows some level of isolation while restricting motion of the panels (11).
