| 20100279590 | Acrylic Polisher - An acrylic polisher includes: a base with two oppositely disposed sideboards with a notch on each of them and a disposition surface in between, a cutting blade set performing a cutting process along the edge of the disposition surface, a stopping board driven by a driving device to move up and downs with respect to the disposition surface. When the stopping board moves downward to the side of the disposition surface, a machining span is formed between the stopping board and the disposition surface. Therefore, as the stopping board lowers to the side of the base, the operator only needs to push an acrylic object toward the stopping board and can quickly obtain the required machining span. The notches on the sideboards of the base form an open space around the disposition surface. The length of the acrylic object is thus not restricted. | 11-04-2010 |

| 20090253356 | APPARATUS AND METHOD FOR POLISHING DRILL BITS - A finishing device for finishing the exterior, flutes and tip of a drill bit is disclosed. The finishing device includes a containment vessel which houses an abrasive media which may have a visco-elastic component and an abrasive component. The drill bit is inserted into or through the abrasive media and rotated. A rotary member may be connected to the shank of the drill bit to provide rotation of the drill bit. The drill bit displaces the abrasive media thereby finishing the exterior, flutes, cutting edges and tip of the drill bit. | 10-08-2009 |
| 20090275272 | AUTOMATIC ROTATION KNIFE SHARPENER - The present invention is directed to an automatic rotation knife sharpener where the crossed sharpening rods are automatically rotated each time a knife is passed down and through the sharpener. The rotation is derived through the means of a spring steel actuator mechanism making contact with the cogwheels of the sharpening rod holders. Magnets retain the sharpening rods in place within the sharpening rod holders. Sharpening rods may be easily removed and stored in troughs on the upper surface of the protective cover. A variety of sharpening rods with different abrasive surfaces can be easily exchanged in the device. | 11-05-2009 |
