Abstract: Provided is a rotary surface treatment tool for removal of paint and other surface substances from such solid materials as wood. The device has a planar circular base which could be attached to a rotational driver via a center spindle. The front side of the base is has a plurality of planar protrusions such as thin flat wires. The protrusions run along the surface of the front side of the base protruding by a few millimeters and lying at an angle to the plane of the base. During operation, the base revolves around a central rotary axis and the front side of the base is applied to the surface to be treated. The planar protrusions positioned on the front side cut into the surface of the object and tear away surface material.

Abstract: An orientation sensitive light for mounting on motorcycles and the like, having a light emitter, an orientation sensitive switch, and a power source, all connected in an electric circuit. The light is mounted on the underside of the motorcycle or on a side of the motorcycle, with the light emitter pointing downwards during normal operational orientation of the motorcycle. An orientation sensitive switch has a cavity with a quantity of an electrically conductive liquid such as mercury. The switch activates the light emitter when the motorcycle changes its orientation, as when a front or a rear wheel is raised above the ground.

Abstract: A glaucoma drainage device implant foldable and rollable upon itself for the drainage of aqueous humor in the treatment of glaucoma comprising an episcleral plate having both an upper surface and a lower surface and a drainage tube having one end terminating above the upper surface of the episcleral plate whereby the glaucoma drainage device may be delivered to the implant site through the lumen of a needle or cannula. The glaucoma drainage device implant may further comprise retainers for maintaining the implant in the proper operable position; a terminal collar for retention purposes; and a peripheral rim, inflatable in some embodiments, for improved filtration.

Abstract: A game apparatus having a game board divided into a grid pattern. Playing paths are arranged to allow player tokens to progress along bordering grid squares in a predesignated manner until player's token enters a center area. Players are rewarded and penalized by landing on grid squares or landing on other player's tokens. Additional ziggurat zones are set aside on the game board providing players with the opportunity to further penalize other players for landing therein. The purpose of the game is to move all four of a specific player's tokens to the center of the board.
