Abstract: A method of phosphorous reduction in stormwater runoff using iron humate, such as in the form of a filter, a layered filter bed, a stacked wall or a liner. The stormwater (fluid) runoff is sent to a fluid retention area such as a retention pond, wetland reservoir or the like where the runoff is filtered through iron humate. While the runoff is filtered, the iron humate absorbs or chemically retains the phosphorous in the runoff to produce filtered runoff with a reduced level of phosphorous. In an alternate embodiment, the runoff can be pumped from a retention pond into a iron humate filter where the runoff is filtered. In another alternate embodiment, the iron humate filter may be placed in a trench below ground to intercept and filter groundwater flows.
Abstract: A top-entry ball valve assembly that includes top and bottom camming plates which are coupled to top and bottom shoulders of the ball valve member. The camming plates include a first pair of opposing camming corner-surfaces to displace the spring-biased valve seat from the perimeter of the ball valve member when it is rotated between open and closed positions. The plates further include a second pair of opposing camming corner-surfaces to fully retract the spring-biased valve seat when being serviced so that the retraction tool can be inserted to hold the seats in place with little or no damage to the forward end of the seats.
Abstract: A gas lamp system and method for lighting the system which utilizes a sparkless flame starter in close proximity to the torch to create a flame.

Abstract: A self-sharpening pocket knife is provided that includes a housing having abrasive stone strips or other sharpening means, and additional means for biasing the strips inward so that as the stone wears down there is always enough surface area in contact with the blade to sharpen it. The biasing means may take the form of foam rubber which expands, or multiple coiled springs, with either means being positioned between the walls of the housing and the stone strips.
Abstract: A coaxial wind turbine apparatus which includes a pair of rearward-mounted, spring-loaded fins to orient the air inlet opening to face the direction of the oncoming wind and close a damper panel or shutter array at the air inlet opening during very high wind conditions. Thereby, the pair of rearward-mounted, spring-loaded fins stabilizes the apparatus during strong ambient wind conditions and minimizes damage to the rotating turbine wheel in the presence of a strong wind.
Abstract: A cylindrical plant container having a dual sidewall and a bottom wall is provided. The inner sidewall is constructed of woven polypropylene fabric and the outer sidewall is constructed of wire, such as chicken wire. The inner sidewall extends above the outer sidewall and is folded over the top of the outer sidewall and is fastened thereto. The inner sidewall also extends below the outer sidewall and is folded over the bottom of the outer sidewall and is fastened thereto. The bottom wall is removably connected to the combined inner and outer sidewall. The bottom wall is of a non-woven polypropylene material. The present invention is designed to be used in a plant nursery. The woven polypropylene permits air to penetrate through the sidewall permitting air pruning of the roots proximal the sidewall. This forces the roots to grow in both a horizontal and downward fashion resulting in a denser plant root system with no spiraling or circling of roots within the cylindrical plant container.
