Abstract: When I thought of the Speed jig it was to help speed up the construction process. The Speed Jig does this by eliminating the need to measure and mark the material being cut when making consecutive cuts using a handheld circular saw. The Speed Jig is simply a rule of measurement that compensates its measurements for the distance from the table of the saw, to the blade of the saw. What you set the measurement on the jig at is what it is going to cut once the table of a circular saw is passed along the fence of the jig.

Abstract: The present invention is an improved method and apparatus for applying liquids to foliage with a roller and height adjustable spray nozzle apparatus. A large heavy roller is pulled or pushed across a field of plants, thereby forcing the plants very close to the ground. A height adjustable applicator nozzle directly following the roller can be adjusted very close to the compacted plants. The combination of an adjustable roller and height adjustable applicator nozzles allows the fluid to be released very near the plants, thereby increasing the amount of fluid transferred to the plants' surface at a reduced rate and increasing the effectiveness of the treatments while lowering the amount of fluid sprayed into the atmosphere. The result of the invention is a savings in the cost of fluids, improved effectiveness of the treatment and an improved environmental impact where the selected fluid has a negative environmental impact.
