Title: Knife sharpener
IPC: B24B3/36
Filed: 1985-03-11
Abstract: An apparatus for sharpening knives, and the like where fixed abrasive elements on an orbiting surface in contact with the knife cutting edge facet move in a mechanically generated uniform cyclic orbit of circumference less than about one (1) inch and through that motion provides the work and energy to sharpen the knife or blade edge. The apparatus provides a circumferential velocity of the abrasive element of less than 800 feet per minute and restrains motion of the abrasive surface to less than ± .005 inch in a direction perpendicularto the intended plane of the knife or knife edge facet. The apparatus contains novel magnetic and other means to steady, guide and control position and angle of the face of the blade relative to the orbiting abrasive elements, to realign any burr or sharpening debris on the knife edge, to control in part the abrading forces, and to remove sharpening debris from the abrasive surface and sharpening zone. A means used to create the orbital motion of the abrasive surface utilizes a pair of synchronously driven eccentric cranks that engage an orbiting drive plate that supports the abrasive surface or surfaces, where the eccentric cranks are mounted on or are an integral part of the shafts of two gear pulleys driven syncronously by means of a motor-driven timing belt, and where the supporting drive plate is constrained to orbit in a prescribed principal plane by means of fixed bearing support points.

Patent EP-0391723-A3 (EP)
IPC: H04N11/02
Filed: 1990-04-05
Abstract: In apparatus for recording/reproducing a component video signal 
having a luminance signal (S YH ) of a wide frequency band so as to be 
reproducible to provide a picture of high resolution and a chroma 
signal (S CL ) in a chroma band included in the frequency band of the 
luminance signal (S YH ) substantially below the high end of the latter, 
a recording signal processing circuit (20) separates (21,10) from the 
luminance signal (S YH ) a slant direction luminance signal (S HY ) in a 
frequency band that includes and extends substantially above the chroma 
band, whereupon the luminance signal (S YH ) is suppressed (12) by the 
slant direction luminance signal (S HY ), and a component of the slant 
direction luminance signal (S HY ) in the chroma band is frequency-­
converted (23,25,26) to a higher band and is frequency interleaved with 
the suppressed luminance signal (S YK ). The chroma signal (S CL ) is 
frequency interleaved (9) with the suppressed luminance signal (S YK ) 
and is then added (13,29) to the latter and to the frequency-converted 
slant direction luminance signal (S LY ) to form the video signal (S ADD1 ) 
which is to be recorded. In the reproducing mode, a circuit (40) for 
processing the reproduced video signal separates (6,7,41-45) therefrom 
the chroma signal (S CK ), the frequency-converted slant direction 
luminance signal (S LY ) and the suppressed luminance signal (S YK ), 
whereupon the separated frequency converted slant direction luminance 
signal (S LY ) is frequency-reconverted (47,49) back to the chroma band 
and into frequency interleaved relation with the suppressed luminance 
signal (S YK ), and the reconverted slant direction luminance signal 
(S SI ) and the separated suppressed luminance signal (S YK ) are added 
(51) to provide a luminance signal (S SHO ) which, with the separated 
chroma signal (S CK ), forms a reproduced component video signal.

Title: Ablation catheter
IPC: A61B17/00
Filed: 1991-08-15
Abstract: An ablation catheter is provided with an elongated member or shaft (110) and a plurality of helically-shaped cutting wires (104) atached to the shaft to form a cutting basket (150). Each of the cutting wires has a section formed as a circumferentially subscribing arc (105) and together the wires present a circumferential cutting area of an essentially cylindrical configuration. Each of the wires (104) comprises a first curved or straight section (123) extending from the distal end of shaft (110) to a discontinuity such as a corner or kink (125). Obstructing matter on the inner surface of a vessel cavity, such as a blood vessel or the like, is separated from the surface as the catheter is moved through the vessel. The catheter may be inserted in a vessel in a standard fashion using a wire guide (102) which extends through a longitudinal passageway in the shaft and a hub (103) interconnecting the basket wire. The shaft and basket together may be contained in an outer sheath to facilitate insertion. The outer sheath with the basket in a collapsed state in the outer sheath may be readily moved past an obstruction, and the sheath withdrawn to allow the basket to expand and come in contact with the interior surface of the vessel cavity. The proximal ends of the cutting wires extend from the shaft through a vibratory transducer, and the distal ends are connected together by a hub. Electrical current is applied to electrical terminals connected to the cutting wires at the proximal end of the shaft to heat the wires to facilitate separating obstructing matter from a vessel surface. Futhermore, the vibration transducer vibrates the cutting wires to further aid in separating plaque and obstructions from soft tissue such as the intima layer of the wall of a blood vessel.
