Patent CA-2359710-A1 (CA)
Title: Epitaxial thin films
Inventor: HWANG TZYY-JIUAN JAN
IPC: H01M8/02
Filed: 2000-01-12
Abstract: Epitaxial thin films for use as buffer layers for high temperature superconductors, electrolytes in solid oxide fuel cells (SOFC), gas separation membranes or dielectric material in electronic devices, are disclosed. By using CCVD, CACVD or any other suitable deposition process, epitaxial films having pore-free, ideal grain boundaries, and dense structure can be formed. Several different types of materials are disclosed for use as buffer layers in high temperature superconductors. In addition, the use of epitaxial thin films for electrolytes and electrode formation in SOFCs results in densification for pore-free and ideal grain boundary/interface microstructure. Gas separation membranes for the production of oxygen and hydrogen are also disclosed. These semipermeable membranes are formed by high-quality, dense, gas-tight, pinhole free sub-micro scale layers of mixed-conducting oxides on porous ceramic substrates. Epitaxial thin films as dielectric material in capacitors are also taught herein. Capacitors are utilized according to their capacitance values which are dependent on their physical structure and dielectric permittivity. The epitaxial thin films of the current invention form low-loss dielectric layers with extremely high permittivity. This high permittivity allows for the formation of capacitors that can have their capacitance adjusted by applying a DC bias between their electrodes.

Title: Weld repair of directionally solidified articles
Inventor: BORNE BRUCE LEONARD
IPC: C22F1/00
Filed: 2000-10-04
Abstract: A directionally solidified nickel-based superalloy article (40) has a defect  (58) therein extending parallel to the solidification direction (54). The article (40) is repaired by removing any foreign matter present in the defec t (58), and then heating the article (40) to a repair temperature of from abou t 60 to about 98 percent of the solidus temperature of the base material in a chamber containing a protective gas that inhibits oxidation of the base material. The defect (58) is filled with a filler metal while maintaining th e article (40) at the repair temperature. The filling is accomplished by providing a source of the filler metal of substantially the same composition  as the base material of the directionally solidified article (40), and melti ng the filler metal into the defect (58) progressively while moving the source of the filler metal relative to the article (40) in a direction parallel to the  solidification direction (54). Optionally, additional artificial heat extraction is accomplished in a heat-flow direction that is within about 45 degrees of the solidification direction (54), as the filler metal solidifies  within the defect (58). The article (40) may thereafter be heat treated.</SD OAB>

Title: Improved resilient, three dimensional polymeric film with slanted capillary apertures, and absorbent article with backsheet comprising the film
Inventor: MARINELLI LUIGI
IPC: A61F13/15
Filed: 2000-03-31
Abstract: The present invention relates to resilient, three dimensional, perforated plastic webs which allow passage of water vapour, and preferably of air, and are resistant to the transmission of aqueous fluids at least in one direction.  According to the present invention the perforated plastic webs consist of a liquid impervious polymeric film having apertures. Theses apertures form capillaries which are not perpendicular to the plane of the film but are disposed at an angle of less than 90~ relative to the plane of the film. The capillaries also have a length L which has a preferred value as compared to the distance that separates a capillary from adjacent ones. The present invention also relates to absorbent articles like baby diapers, adult incontinence articles and in particular to sanitary napkins or pantiliners which have a topsheet on the surface facing the wearer in use. According to the present invention the articles are provided also with an apertured backsheet for breathability. The backsheet comprises at least one breathable layer of a resilient, three dimensional, perforated plastic web as described above.
Patent CA-2371209-A1 (CA)
Inventor: ROSE BRENDA H
IPC: B01J29/74
Filed: 2000-05-12
Abstract: This application is related to a process for hydrocracking of heavy naphtha feeds. An improvement in the selectivity of the hydrocracking process was observed by decoupling aromatics saturation and hydrocracking reactions. Thi s benefit has been observed for hydrocracking with either noble metal or base metal catalysts. The improved selectivity was observed in a low pressure as well as standard pressure operation. A decrease in the amount of light gas ( C1- C4) and an increase in the amount of liquid product produced was observed. Decoupling the aromatic saturation and hydrocracking reactions also resulted  in a significant improvement in process operability (i.e., decreased runaway  tendency) and controllability and a reduction in catalyst deactivation rate.

Patent CA-2376408-A1 (CA)
Inventor: MISKA STANLEY R
IPC: B32B15/08
Filed: 2002-03-14
Abstract: A conductive gasket is disclosed for use in apparatus to block the exit or entry of electromagnetic interference (EMI) between adjacent metal surfaces of the apparatus. The gasket is formed at least in part by a polymeric film having an outward facing surface embossed so as to provide a plurality of peaks distributed over the surface. A metal is coated, by vapor deposition, onto the surface so as to over lie the peaks. This provides the film with a conductive surface. When located between adjacent metal surfaces, abrasion of the metal coating from the peaks over time does not adversely affect the conductive properties of the film surface.  This is because the wearing away of the metal from the tops of the peaks exposes a cross section of the metal at the sides of the peaks, which remain in contact with the adjacent metal surfaces of the apparatus.
