Title: An inverse shape replication method for forming metal matrix composite bodies and products produced therefrom
Inventor: WHITE DANNY R
IPC: B22F3/26
Filed: 1989-10-13
Abstract: The present invention relates to the formation of metal matrix composite bodies by a spontaneous infiltration technique, and novel metal matrix composite bodies produced according to the method. An ingot of matrix metal is surrounded by a permeable mass of filler material. An infiltration enhancer and/or an infiltration enhancer precursor and/or an infiltrating atmosphere are also in communication with the filler material, at least at some point during the process, which permit the shaped ingot of matrix metal, when made molten, to spontaneously infiltrate the surrounding permeable mass of filler material. After the spontaneous infiltration, a metal matrix composite body is produced having therein a cavity which substantially corresponds in shape to the original ingot of matrix metal.
Patent CA-2002986-A1 (CA)
Title: High strength optical fiber splice
Inventor: HSU HUI-PIN
IPC: G02B/
Filed: 1989-11-15
Abstract: ABSTRACT      Two optical fibers (22,24) are spliced together to form a single spliced optical fiber.  The spliced region is uncontaminated by impurities, and has substantially no loss of optical transmission or mechanical strength as compared to the other regions of the fibers.  Splicing is accomplished by removal of the buffer coating (16), if any, cleaving of the fibers to be spliced to form facing splicing surfaces, careful precleaning of the cleaved fibers in the region adjacent the splicing surfaces, aligning the fibers using optical transmission as the alignment criterion, fusing the fibers together by pre-heating the region to be spliced, fusing the region, post-annealing the spliced region, carefully postcleaning the spliced region, and recoating the spliced region with a UV curable polymer buffer material, if desired.  The heating of the fibers to accomplish the fusion is desirable accom-plished by a laser such as a carbon dioxide laser (50).
Patent CA-2004050-A1 (CA)
IPC: C02F1/20
Filed: 1989-11-28
Abstract: When an aqueous system containing dissolved oxygen and erythorbate or ascorbate is passed through an activated carbon bed, the oxygen is removed at ambient temperatures.

Patent CA-2004444-A1 (CA)
Title: Arrester with external isolator
Inventor: VEVERKA EDWARD F
IPC: H02H3/04
Filed: 1989-12-01
Abstract: An arrester for an under oil transformer is connected between a primary bushing lead and an insulator/isolator penetrating the wall of a housing which encloses the oil, arrester, and transformer parts.  A ground wire outside the housing is removably connected to the isolator which functions as a circuit disconnector.  The ground wire is removed to open circuit the arrester so that the transformer may be tested without having to disable any parts in the housing.       Responsive to an arrester failure, the ground wire is blown away to give a visual indication of the failure.  The blowing away of the ground wire eliminates the need for the arrester to fail in an open circuit condition.

IPC: A61P25/28
Filed: 1990-01-02
Abstract: The present invention relates to neurotrophic factors, ciliary neurotrophic factor (CNTF) in particular, as well as methods of purifying CNTF and producing recombinant CNTF. A purified single protein species ciliary neurotrophic factor (CNTF), particularly sciatic nerve ciliary neurotrophic factor (SN-CNTF), having a specific activity increase to greater than 25,000-fold from crude form is produced by recombinant DNA methods including, but not limited to, the steps of acid treatment, chromatofocusing, SDS-PAGE gel and reverse phase-HPLC.  Said purification is useful in that it provides probes that facilitate the screening of cDNA and genomic libraries in order to clone genes encoding CNTF. The present invention also provides nucleic acid and corresponding amino acid sequences for CNTF.
