Patent CA-2518430-A1 (CA)
Inventor: IWAKI KATSUNORI
IPC: A45D20/06
Filed: 2004-03-05
Abstract: A gas combustion device (1) has a combustor (11) for burning a fuel gas fed from a gas-feeding source, a blower (15) for regulating the amount of air inside a tubular casing (5) in which the combustor (11) is installed, an ejector (7) with a primary- air hole (37), and an igniter (9) for igniting a mixture gas jetted from a wick (39) provided forward of the ejector (7). The primary-air hole (37) sucks primary air into a gas flow path that is led from the gas-feeding source to the combustor (11), the sucking being induced by negative pressure produced by a flow speed of the fuel gas fed to the combustor (11). To ignite the mixture gas from the wick (39), the amount of air inside the casing (5) is reduced to increase the ignitability of the mixture gas. Once ignited, combustion is sustained with the combustibility of the fuel gas in the combustor (11) increased by an increased amount of air in the casing (5).

Patent CA-2523615-A1 (CA)
Title: Stability-kerfing of green lumber to obtain improvements in drying and future utilization
Inventor: ERICKSON ROBERT W
IPC: B27N7/00
Filed: 2005-10-18
Abstract: A technique for end-grain creation is employed for obtaining rapid and uniform drying of lumber while simultaneously reducing warp. The stability-kerfing responsible for the improved drying of the lumber decreases the edgewise bending strength by less than ten percent, a loss readily recovered due to the ability of stability-kerfing to achieve lower and more uniform moisture contents than those realized in the contemporary drying of lumber. This overall improvement in moisture content greatly increases the edgewise bending strength for stability-kerfed construction lumber by comparison to that for contemporary construction lumber. Its improved moisture condition at the time of entry into the marketing stream also fosters future dimensional stability compared to that for contemporary lumber. The required stability-kerfing is easily accomplished by the specialized implementation of existing saw equipment and associated technology into the contemporary processing lines.

Title: Multiple filament nasal strip with high peel angle release
Inventor: FENTON GUSTAV
IPC: A61F2/82
Filed: 2004-08-23
Abstract: The present invention relates to improved nasal dilators that prevent the outer wall of tissue of nasal passages of a nose from drawing in during breathing. The improved nasal dilator has a resilient element, or "spring," made up of a plurality of small filaments for keeping the nasal passages from drawing in while breathing. The filaments may be a variety of shapes and sizes and may run both along the length of the nasal dilator and at a variety of different angles relative to the length of the nasal dilator.

Filed: 2004-06-18
Abstract: The present invention provides a method of predicting the risk of a patient for developing adverse drug reactions, particularly Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), or drug hypersensitivity syndrome (HSS). It was discovered that an HLA-13 allele, HLA-B* 1502, is associated with SJS/TEN that is induced by a variety of drugs. The correlation with HLA-B* 1502 is most significant for carbamazepine-induced SJS/TEN, wherein all the patients tested have the HLA-13*1502 allele. In addition, another HLA-13 allele, HLA-B*5801, is particularly associated with SJS/TEN or HSS induced by allopurinol. Milder cutaneous reactions, such as maculopapular rash, erythema multiforme (EM), urticaria, and fixed drug eruption, are particularly associated with a third allele, HLA-13*4601. For any of the alleles, genetic markers (e.g., HLA markers, microsatellite, or single nucleotide polymorphism markers) located between the DRB1 and HLA-A region of the specific HLA-B  haplotype can also be used for the test.
