    Abstract: A pressure relief vent on a container includes a flat diaphragm fastened to the exterior of a container so as to cover an opening in the container. The diaphragm is fastened to the container at its perimeter and at at least one point within its perimeter. The shape of the peripheral fastening seam and the number of and size of the point fastenings determine and stabilize the vent pressure at which the diaphragm ruptures.

    Abstract: A lawn maintenance device is provided. The lawn maintenance device has a generally planar rail system which is permanently inserted into the ground. The top portion of the rail system remains above ground while the remainder of the rail system is underground. A movable tool having a corresponding groove which aligns with the rail runs along the rail and a blade attached to the movable tool trims the lawn or vegetation. The rail provides a thin section of vegetation which can be easily cut.

    Abstract: A method of simultaneously preparing and plating two parts attached together in an assembly, which parts are of different materials, such as steel and aluminum, and are incompatible with one another in the plating preparation process. The method includes the steps, in the following order, of (a) degreasing such an assembly with trichloroethylene vapors for a period of 3 to 5 minutes, (b) clean with a heated alkaline cleaner for a period of 15 seconds, then rinse with water, (c) clean with muriatic acid for a period of 5 seconds, then rinse with water, (d) repeat steps (b) and (c) once again, (e) dip assembly in zincate solution for a period of 2 minutes, then rinse with water, and (f) plate the exposed surfaces of the assembly. The method also includes the steps of first cleaning the parts separately, attaching the parts together, and machining the assembly before initiating the above steps. An article constructed in accordance with the above is also disclosed.
