Abstract: The maze game consists of a plurality of horizontal segments and a plurality of vertical segments that define a two-dimensional array of m×m squares or spaces where the size m is selectable by the user. In each potential segment location the present invention randomly locates: (1) a solid wall corresponding to a portion of the maze walls; (2) an opening creating a passage way through the maze; (3) special feature; or (4) the refuge, of which there is precisely one per maze. At the beginning of the game, the maze is invisible to all players. As the players move through the initially invisible maze, the maze walls adjacent each player's position become visible in a manner dictated by a particular vision setting selected at the beginning of the game. The goal of one player, who may be represented in the game as a cat, is to catch the other player, which may be represented in the game as a mouse, by occupying the mouse's location, i.e., by landing on the mouse.

Abstract: A movable rip fence is adapted for installation on the work table having a planar surface with a pair of rails on opposite sides that are provided with a series of evenly spaced apart holes, and with a cutting tool between the rails that extends above the table surface. The fence comprises an elongated main frame unit that extends between the rails including movable pins at opposite ends for holding the main frame unit generally perpendicular to both rails. A first control device on the main frame which enables the pins to be inserted and retracted into and out from a preselected pair of holes in the rails to first hold the main frame firmly in a predetermined fixed position and thereafter release it for movement to another position. An elongated guide member having an outer planar surface is positioned adjacent and parallel to the main frame and is yieldably attached to it.
