Abstract: A universal weed cover system is installed at the root of a vertical structure of various kinds so as to cover the ground around the structure to prevent the growth of weeds. The universal weed cover is thin, flexible and essentially rectangular. The system comprises a plurality of panels with one or more cut-out sections, sized to fit around the structure. The panels are interconnected and fastened to the ground by fastening means through slot openings at one end of the universal weed cover. The slot openings allow the relative movement of the adjacent covers due to expansion and contraction of the covers caused by ambient heating and cooling. Ribs and/or webs are provided for strength and to channel water off the surface of the panels. A cover is provided when the cut-out opening is greater than the diameter of the vertical structure. The cover has a central flap and is placed over the exposed ground in the post hole and directly on top of the joining universal weed covers.

Abstract: A method for manufacturing insulating plates with accurately located holes in patterns suitable for bed of nails type test heads. An optically aligned drilling machine is used to form holes in the insulating plate conforming to the test pattern by using a reference pattern photolithographically formed onto the insulating plate. The photolithographic formation provides a pattern of greater accuracy and maintains that accentuated degree of accuracy through camera alignment and fixed offset between commonly mounted camera and drill. The tighter registration of copper features in advanced printed circuit boards subject to testing with the bed of nails test heads require insulating plates hole patterns with the accentuated accuracy provided by the method.

Abstract: A system for transferring finger and thumb hole locations from a first bowling ball having finger and thumb holes to a second bowling ball which employs a transparent template marked to show the hole locations and the location of the first bowling ball positive axis point. The template is applied to the second bowling ball and that ball marked through the marks indicating the hole locations.
