Abstract: A completed, solved game puzzle 10 is a mobius strip made of multiple columns 24 and rows 22 of blocks 20, or block-like pieces. Each block 20 has opposing display surfaces and opposing connecting surfaces which are orthogonal to the display surfaces. The connecting surfaces have mechanisms such as a corresponding peg 30 and aperture 32, respectively, for connecting one block 20 to another block 20. The display surfaces exhibit a color, alphabet 28, number or symbol. The unsolved puzzle is one or more bands of blocks connected by and pivotable about an axis 26 extending through the center of each block 20 parallel to the display and connecting surfaces. The solution to the puzzle may be words or phrases spelled by aligned letters of individual strips, or a predetermined pattern formed from aligned colors or symbols. To solve the puzzle, the blocks of each strip must be connected adjacent the blocks of another strip at appropriate locations.

Abstract: A cutting guide for hand-held routers has a guide fence which pivots about a base. The guide fence engages a workpiece and provides a steady support for a variety of routing operations including bevelling or chamfering, splining, rabbeting, dadoing and edging. The cutting guide also has an after-cut guide to provide additional support.
