Abstract: A multi-port check-valve for a fuel vapor emissions system coupled to an intake manifold of an internal combustion engine with forced induction and of the type including a purge canister and a purge valve, comprising a first port coupled to the purge valve, a second port in fluid communication with the first port and having a first check-valve with a fixed orifice arranged to open in response to engine vacuum, and bleed intake manifold boost pressure.

Abstract: The present invention is a topical skin preparation for treatment of fungal infections of the skin and nails. The preparation comprises triacetin in combination with an antifungal agent. In a preferred form, the preparation further comprises, a fatty acid source such as a fish oil. In a preferred embodiment, cod liver oil and tolnaftate are used in combination with triacetin. The concentrations of these constituents are 96.0-99.0% concentration triacetin, 0.5-3.0% concentration tolnaftate and 0.5-1.0% concentration cod liver oil, in one preferred embodiment. Other compounds, such as ethyl alcohol, amino acids such as n-acetylcysteine, and herbal additives may also be added to the preparation. Further, other antifungal agents such as nystatin, clortimazole, econazole, ketoconazole, miconazole, solconazole, oxiconizole, naftifine, terbinafine, and butenafine, for example, may be substituted for the antifungal agent tolnaftate.

Abstract: A method of welding age-hardenable aluminum alloys to improve strength properties in the heat affected zone and the weld zone, the method comprising the steps of providing precipitation hardenable aluminum alloy members to be welded and subjecting said members to a first aging step for times and temperatures to generated strengthening precipitates. Thereafter, the aged members are welded to provide a welded assembly having a weld zone. The welded members are subjected to a second aging step to reprecipitate strengthening precipitates dissolved in the weld zone.
