Patent number: 7422180Abstract: The present invention relates to a magnetic knife stand which comprises one or more slits for inserting knives. On the upper inner side of each inserting slit, one or more magnets are disposed. A hole or a hollow is disposed on the upper inner side of each inserting holes, and the magnet is placed inside the hole or hollow on the upper inner side of the inserting slit. During and after the process of inserting the knives into the knife stand, the magnets will keep the cutting edges of the knives away from the bottom inner sides of the inserting slits, thereby effectively preventing the edges from becoming blunt, which is caused by their rubbing against the inserting slits. The frequency of sharpening the blades can be reduced and the lifespan of the knives can be extended. Further, this magnetic knife stand is more effective in protecting the knife stand from being cut or worn out by the knives. This invention enables the knives to be stored securely in the knife stand.Type: GrantFiled: December 19, 2005Date of Patent: September 9, 2008Assignee: Viceversa International LimitedInventor: Siu Nam Tang

Patent number: 7275461Abstract: An apparatus and method for sharpening razor blades and the like whereby rectangularly-shaped magnets are placed end-to-end in a rectangular enclosure that snaps on securely over a razor blade during non-use times in such a manner that the magnetic field generated by the magnets acts upon the cutting edge of the blade so as to maintain the sharpness of the cutting edge.Type: GrantFiled: March 4, 2006Date of Patent: October 2, 2007Inventors: Richard Joel Gherman, David D. Hayslett

Patent number: 6559563Abstract: An improved linear oscillating actuator is capable of minimizing the undesired vibrations while moving first and second oscillators in parallel paths. The first and second oscillators carry first and second drive elements respectively for driving connection to individual reciprocating loads. The first and second drive elements project upwardly respectively from the first and second oscillators such that the first drive element is disposed immediately upwardly of the second oscillator and the second drive elements is disposed immediately upwardly of the first oscillator. With this reverse arrangement of the first and second drive elements relative to the first and second oscillators, the individual oscillating systems each including the oscillator, the drive element and the corresponding reciprocating load can have its mass center disposed in close proximity to a mass center of the actuator, thereby enabling to reduce undesired vibrations which would otherwise occur around the mass center of the actuator.Type: GrantFiled: June 7, 2001Date of Patent: May 6, 2003Assignee: Matsushita Electric Works, Ltd.Inventors: Hiroaki Shimizu, Ryo Motohashi, Hidekazu Yabuuchi, Takahiro Nishinaka, Noboru Kobayashi

Patent number: 6463661Abstract: A magnetic shaving system includes a pre-trimming solution containing particles having magnetic properties and a shaving apparatus having a magnet. The shaving apparatus may include only a magnet or may include a magnet in proximity of a typical razor blade. The pre-trimming solution is applied to the desired area and the magnetic shaving apparatus is applied over the solution. The magnetic solution surround the hairs and causes the hairs to be drawn toward the magnetic shaving apparatus and away from the skin, yielding a more comfortable and effective shave.Type: GrantFiled: May 23, 2001Date of Patent: October 15, 2002Inventor: Adam M.
