Abstract: A chain saw handle extension that includes an attachment mechanism at the far ends thereof for securement to a top and a bottom of a chain saw; and a clamping structure attached to the attachment mechanism that is clampable about the bottom of an existing chain saw handle and a bottom end of the extension; the extension including a speed control trigger connectable to the control trigger of an existing chain saw that is located such that the speed control trigger of the chain saw handle extension is positioned well behind the existing trigger of the chain saw; each of the attachment structures at the end of the V-shaped structures including a threaded knob which is threadable into a threaded aperture that is provided within a body of a chain saw attached to the existing chain saw handle.

Abstract: A method of achieving an increased muzzle loaded, black powder hunting rifle firing rate and a muzzle loaded black powder hunting rifle used to practice the increased muzzle loaded, black powder rifle firing rate method of the invention.

Abstract: A float tube cover for covering the exterior of an inflated inner tube or the like with a fabric material which will prevent adhesive burns and abrasions and also prevent the inner tube from becoming excessively heated from exposure to the sun. The cover is desirably provided with a leash to allow the user to retrieve the tube should the fall off of the tube as well as one or more pockets for holding items such as suntan lotion, sunglasses, and the like.

Abstract: A tie-down assembly accessory that includes a main strap section and first and second securing/slide loop straps. The first and second securing/slide loop straps are configurable by the user to form a slide loop for slidably receiving the securing strap of a tie-down assembly and a securing loop for securing the securing straps during storage or the end of a securing strap pulled past the take up assembly during installation of the tie-down assembly.

Abstract: A method and system for preventing vehicle misfuelling by utilizing an apparatus that receives a fuel nozzle into the filler neck, and activates a vacuum on the nozzle inserted therein. Using the pump's internal shut-off mechanism, this prevents the fuel pump from dispensing fuel until the sensing unit within the apparatus is able to identify the fuel proposed to be added to the tank. If the fuel is deemed acceptable, the vacuum is released, and the fuel is permitted to enter into the desired fuel tank.

Abstract: A mail container with a contaminant indicator mechanism in the form of a perimeter edge viewing window is provided for verifying that a mail item received does not contain a biological hazard in the form of a loose particulate such as powders, granules, and the like. In order to attract the attention of the mail recipient that particulate matter may be contained in a mail container, an area having a quantity of clear, adhesive on only a portion of one or more of the transparent perimeter edge viewing windows so that the mail recipient or delivery person could immediately identify the existence of particulate matter contamination.

Abstract: A fluid cooled speaker having a T-yoke with a pole piece, a magnet surrounding the pole piece, a voice coil positioned between the pole piece and the magnet, and a cone connected to the voice coil. The T-yoke includes a body having a base and a pole piece with a sealed cavity formed within the pole piece. The T-yoke also has a fluid inlet and outlet formed in the body and communicating between the cavity and an area outside the body of the T-yoke.

Abstract: A facial skin protective assembly for reducing and/or eliminating pulling and pushing forces on the facial skin surfaces that occur while sleeping. The facial skin protective assembly includes a face shield cage structure, a number of securing straps attached to the face shield cage structure and being extendable about the sides and back of the user's head in a manner to comfortably but firmly hold the face shield cage structure in place while the user is sleeping, and, as an option, a number of heat/cool insert cushion cells.

Abstract: A drilling fluid or mud having several components, including leonardite (humic acid); potassium acetate; partially hydrolyzed polyacrylamide (PHPA); polyanionic cellulose polymer (PAC); sulfonated asphalt; sulfoalkylated tannin; polystyrene maleic anhydride copolymer; micronized cellulose fiber; calcium carbonate; and calcium carbonate. These components are preferably premixed in a dry formulation as a powder or as pellets, and shipped to the site in bags or bulk barrels. This offers substantial advantages over the prior art in that the drilling mud of the present invention may be formed simply by adding the dry mix to a predetermined amount of water, and is thus much easier to make than the prior art wet mix drilling fluids, which typically require precise ratios of several different powders and liquids to be mixed together. The humic acid serves as hydration buffer to help keep the powder or pellets dry and flowable.

Abstract: A vapor evacuating device that enables product offloaders to quickly, easily, and safely offload chemicals and the associated vapors from vessels with minimal environmental impact and inconvenience by combining vapors from a tanker vehicle with an evacuation fluid, such as water, in order to yield a solution that is easily and safely disposed.

Abstract: According to the present invention, the flow-activated valve assembly is a fluid-driven tool for use in various down hole drilling and fishing operations, which is activated by the introduction of fluid into an enclosed assembly, whereby fluid forces a movable portion of such assembly to slide until it engages a stationary portion, where an impact is realized, and at which time the fluid is permitted to exhaust. Upon this impact, another valve is opened to permit fluid to flow in another channel, moving the assembly in the opposite direction until it reaches a second stationary portion, at which point another impact is realized in the opposite direction. This creates a bi-directional hammering effect for each cycle of the tool, which can be utilized in various applications, either for the jarring effect, the linear motion, or a combination of both.

Abstract: An improved apparatus and method for the prevention of deformation and buckling of metal plates during welding processes is disclosed. The improved apparatus and method are used to apply pressure to a welded seam created between two metal plates during the welding process. Pressure is applied to the area of the plates surrounding the welded seam until the welded seam has sufficiently cooled to prevent deformation and buckling of the metal plates.
