  • Patent number: 7887397
    Abstract: A knife sharpening bar includes a handle that carries a support bar. A flexible tube is tightly fit over the support bar. A hollow ceramic bar is then fit over the flexible tube with an inside surface of the ceramic bar tightly engaging the flexible tube so that the flexible tube provides a cushioning support between the support bar and the ceramic bar, which protects the ceramic bar from directly bearing any external impact applied to the knife sharpening bar. An internally-threaded cap engages an externally-threaded free end of the support bar and abuts against the ceramic bar to thereby secure the ceramic bar in position on the support bar. Collars or other buffering members can be positioned at opposite ends of the ceramic bar.

  • Publication number: 20100199826
    Abstract: It is an object of the present invention to provide a cutting machine capable of sharpening in such a manner that an angle of a cutting edge can be kept constant. A support block 14 is provided with two arms 14a, 14b which are spaced at a certain angle, and the arms 14a, 14b have rotation shafts 12a, 13a of rotary whetstones 12, 13, respectively, extending upright from the vicinities of the front ends thereof. The rotary whetstones 12, 13 has, at front ends thereof, flat surfaces perpendicular to the rotation shafts 12a, 13a to sharpen the one side 11b and the other side 11c of the cutting edge 11a of the cutting blade 11, respectively. The whetstone holding mechanism 15 can be moved in parallel linearly or can swing almost linearly, as mainly indicated by the arrow 15a, to bring the flat surface 12b of the rotary whetstone 12 into contact with the one side 11b of the cutting blade 11, as depicted by a broken line, thereby allowing the switch to the sharpening state.

  • Publication number: 20100159814
    Abstract: A system and method for cleaning receiver slots with hook-fits for stator blade ring segments. A first cleaning tool with an abrasive coating and sideward projection in the shape of the hook is slid through the slot using the hook-fit as a guide. A second cleaning tool with an abrasive coating and a formed/machined hook-fit used as a guide while cleaning the receiver slots as it is pushed through the receiver slots. The tools remove trash, oil rust/oxidation, and other foreign materials from receiving slot. Both tools may attach to a metal rod with two knuckles as part of the handle that connects to and uses the hook-fit as a guide enabling the operator to reach deep into the radius of the compressor case receiver slots and hook-fits located adjacent to and beneath the rotor and rotor blades so that the hook-fit and receiver slot can be thoroughly cleaned.

  • Publication number: 20100075583
    Abstract: A sharpening apparatus having a slightly convexly or concavely curved abrasive surface, for use in sharpening woodworking tools or in other fields requiring such processing of precision parts or tools. The invention may further employ either cylindrical or conic abrasive surfaces. Cylindrical abrasive surfaces are desirable when a curvature of a fixed radius is desired, or where accuracy of the curvature radius is required. Conic or semi-conic surfaces may be used to enable a user, by means of short sharpening strokes, to achieve an approximate desired curvature among a range of possible curvatures provided along the length of the abrasive surface as the curvature radius progressively declines. In this way, one abrasive surface may be used to achieve a variety of curvatures.
