Finishing of Difficult Surfaces U.S. Patent 5,507,685. Apr. 16, 1996 S. E. Hoffman, Englewood C/if%, N.J.
A method for finishing a surface of a workpiece, comprising agitating with a first mixture including a first plurality of discrete, homogeneous compressed felt chunks having a first particulate abrasive coating thereon; and agitating with a sec- ond mixture including a second plurality of discrete, homogeneous compressed felt chunks having a second particulate abra- sive coating thereon, the second particulate abrasive coating having an abrasive size smaller than the first particulate abrasive coating.
Apparatus for Electrolytic Polishing U.S. Patent 5,507,923. Apr. 16, 1996 H.J. Sfouse et al., Houston
A method for electrolytically polishing an inside surface of a tubular product, which comprises placing a cathode head inside a first reservoir located adjacent one end; providing a second reservoir located adjacent another end; flowing an electro-
lyte through the first reservoir, the tubular product and the second reservoir, and over the cathode head; establishing an electric potential between the tubular product and cathode head; displacing the cathode head from the first reservoir along the length of the tubular product; and causing ionic dis- placement between the tubular product and the cathode head.
