| 20090023367 | DEVICE AND METHOD FOR SHARPENING BLADES - A blade sharpener includes a blade holder for holding a blade to be sharpened by a rotary wheel having an abrasive surface. The blade holder includes a body having a notch formed in a medial portion of the body for exposing a portion of the blade to the abrasive surface and a support surface for supporting the blade as it travels through the blade holder. The notch comprises a curved back wall for accommodating the rotary wheel. | 01-22-2009 |
| 20100233942 | APPARATUS FOR APPLYING A FINISH TO A METAL SURFACE AND METHOD OF APPARATUS CONSTRUCTION - An apparatus for applying a lightly scratched surface to a metal sample comprises a motor, a disk, a frame, a motion guidance unit, and a plurality of springs. The motor may provide a rotational motion to the disk which includes abrasive elements configured to create a plurality of microscopic scratches on the surface of the metal sample. The frame may include a bottom wall with an opening in which the motor is positioned. The motion guidance unit may retain the frame and guide the motion of the motor across the surface of the metal sample. The plurality of springs may couple the motor to the bottom wall of the frame in order to suspend the motor within the opening of the bottom wall and to allow lateral motion of the motor and the disk while the motor is rotating. | 09-16-2010 |
| 20110136413 | BLADE SHARPENING SYSTEM FOR MULTIPLE BLADE SHAPES - A blade sharpening system using the interior surface of a grinding wheel against which a blade is drawn along its entire length for sharpening. The sharpening system includes a blade holding configuration having multiple hinged arms. A cam operating between two of the hinged arms serves to alter the angle of incidence between the blade and the grinding wheel as the blade is drawn across the grinding wheel. The result is that a wide variety of different blade configurations can be easily accommodated by the sharpening system. | 06-09-2011 |
| 20110136414 | POLISHING HEAD AND POLISHING APPARATUS - A polishing head for holding a workpiece when a surface of the workpiece is polished and a polishing apparatus provided with the polishing head, and more particularly a polishing head for holding the workpiece on a rubber film and a polishing apparatus provided with the polishing head. The polishing head and the polishing apparatus provided with the polishing head that can adjust the polishing profile on the basis of the shape of the workpiece before polishing and can stably obtain good flatness. | 06-09-2011 |
| 20120208440 | FLEXURE ASSEMBLY - A flexure assembly comprising a flexure stack comprising a plurality of individual webs connected together with a force in an x-direction to produce a friction in a z-direction orthogonal to the x-direction between the plurality of webs, the friction holding the plurality of webs in engagement. In some embodiments, the flexure assembly includes a second flexure stack fixedly spaced from the first stack comprising a second plurality of individual webs connected together with a second force in the x-direction to produce a second friction in the z-direction between the second plurality of webs. The flexure assembly may be used, for example, for supporting a workpiece such as a slider row bar in a lapping machine. | 08-16-2012 |
| 451279000 | Reversing, obverting, or pivoting | 1 |
| 20110237166 | BED-TYPE CIRCULAR SAW BLADE GRINDER - A bed-type circular saw blade grinder includes: a bed section; a support section fixedly connected with the bed section, a circular saw blade being rotatably connected with the support section; a rotary seat pivotally disposed on the bed section via a pivot shaft and reciprocally rotatable about the pivot shaft between a first position and a second position, the rotary seat having a first connection section and a second connection section positioned on two sides of the pivot shaft; a circular saw blade restriction section disposed at the first connection section for driving the circular saw blade to intermittently rotate; and a grinding unit disposed at the second connection section for grinding saw teeth. When the rotary seat is pivotally rotated between the first and second positions, the rotary seat drives the circular saw blade restriction section and the grinding unit to move with the rotary seat. | 09-29-2011 |
