Patent CA-2641309-A1 (CA)
Title: Functionalization of paper components with an amine-containing polymer
Inventor: BERG MICHAEL C
IPC: D21H17/20
Filed: 2007-02-05
Abstract: Compositions and methods of producing paper-based materials are disclosed. In general, the techniques utilize an amine-containing polymer, such as chitosan, to fiinctionalize one or more components of a mixture used to form materials such as paper-based materials. Such components can include the fibers of a pulp and/or filler particles. In one instance, either the pulp or the filler particles are functionalized, but not both. Such functionalization can improve the qualities of a paper-based material relative to when such functionalization is not utilized. Techniques and compositions are also described to further improve the qualities of a paper material by utilizing a complementary polymer which can couple with the amine-containing polymer.

Title: Methoxypolyethylene glycol thioester chelate and uses thereof
Inventor: SHAEFFER JAMES
IPC: A61K31/21
Filed: 2007-02-14
Abstract: The present invention is directed generally to protecting cells, tissues and organs against the damaging effects of ionizing or other damaging agents associated with radiation or chemotherapy, or degenerative diseases or processes of various organs that elicit the production of free radicals or oxidants such as peroxides, superoxide anions, hydroxyl radicals or nitric oxides, or heavy metal cations. More particularly, the present invention is concerned with methoxypolyethylene glycol thioester chelate methyl esters that are useful as protectors against tissue damage by penetrating the cell membrane to remove electrons from free radical oxidants and remove heavy metals that may react with peroxides to produce the reactive hydroxyl radical, or remove Ca++ that may be released from organelles. These chelate esters will also have utility in reducing intraocular pressure in glaucoma patients.

Title: Multi-objective optimal design improvement support device, its method and storage medium
Inventor: ANAI HIROKAZU
IPC: G06F17/50
Filed: 2009-04-22
Abstract: A multi-objective optical design improvement support device calculates a logical expression indicating a logical relationship among arbitrary two or three objective functions of a plurality of mathematically approximated objective functions and displays a possibility area in arbitrary objective space according to it. When a designer is not satisfied with an optimal Pareto solution, it copies a sample point group out of the initial constraints of a design parameter set in the objective space, displays its result and presents an improvement solution to the designer. When the designer finds more optimal solution than the optimal Pareto solution among the displayed improvement solutions and gives instruction, it calculates a sample point in design parameter space, corresponding to the optimal improvement solution, overlaps it with a constraint range and displays it as improvement knowledge and information.

Patent CA-2667458-A1 (CA)
Inventor: KOLLGAARD JEFFREY R
IPC: B64F5/00
Filed: 2007-10-10
Abstract: First and second thermal sensors measure the respective temperatures of portions of a surface of a structure such as an aircraft component. An alert signal is emitted if the temperatures of the surface portions are substantially different. An energy source causes heat flow within the structure. Subsurface flaws such as disbonded areas between composite layers and foreign materials obstruct heat flow within the structure and cause proximate surface portions to exhibit different temperatures. A non-alert signal may be emitted if the temperatures of proximate surface portions are essentially the same.
