An abrasive grit for a metal bonded Single Layer abrasive tool includes abrasive grains coated with a first active component. The active component is mechanically-bound to the surface of the superabrasive grains. Preferably the abrasive is a superabrasive, especially diamond, and the first active component is titanium, either in the form of elemental Ti or TiH.sub.2. The novel grit is made by mixing the first active powder component in a liquid binder to form an adhesive paste; mixing the paste with the abrasive grains to wet the grains, and drying the mixture to adhere active component to the grains. The coated abrasive can be brazed onto a core to form a Single Layer tool, especially with a brazing composition that includes a bronze alloy and small concentrations of a second active component. During brazing the novel abrasive grains provide excellent surface contact with the brazing composition and the braze strongly bind the grains to the tool core. The brazed composition is easy to chemically or electrochemically strip from the cores of worn abrasive tools to permit reconstruction of the tools.

Abrasive tool containing coated superabrasive grain

An arcade basketball game which has a transparent enclosure (20) with basketball hoops (40) and a miniature basketball (28) inside. A pair of inclined playing surfaces (30) join together in a peak with transparent vertical barrier (34) on top, allowing the ball to roll to the lowest point where a striker bar (36) impedes its travel. An open space between the bar and the playing surface allow a hand held striker (52) to hit the ball upward at an angle toward the opposite players hoop in an attempt to score a goal. A shot blocker (70) and a pair of tip in hands (78) that are electrically controlled by a joystick (76) and hand switches (86) move in order to help or hinder the flight path of the ball. A game time display (60) indicates elapsed time and a pair of scoreboards (68) denote the scores of each player.

Basketball game adjustment apparatus

A putting practice device (10) that may be used indoors or outdoors to improve a golfers putting. The device (10) consists of a putting surface (14) having therein a golf cup (16), a first golf ball (20) pivotally mounted adjacent one edge of the cup, a lever (30) coupled to the first golf ball (20) to facilitate movement of the first golf ball out of the cup (16), a second golf ball (40) positioned adjacent the opposite edge of the cup (16) from the first golf ball (20), and indicia showing desired movement of a golf club during a proper putting stroke. When the first ball (20) is struck, it pivotally falls into the cup (16) and the 'follow through' will then strike the second ball (40). If the 'follow through' is correct the second ball will continue in a straight path; if not, the ball (40) will go to one side or the other indicating a correctable problem.
