SURFACE-HARDENED M E T A L SHOT
U.S. Patent 6,018,854. Feb. 1, 2000 Y. Miyasaka, assignor to Fuji Kihan Co. Ltd., Aichi, Japan
A m e t h o d of m a k i n g surfacehardened metal shot comprising accommodating a predetermined quantity of shot in a first container of a blasting machine; accommodating a predetermined quantity of ferrous metal shot material in a second container of the blasting machine, the shot having a hardness that is at least equal to that of the ferrous metal shot material; and blasting the shot accommodated in the first container against the ferrous metal shot material accommodated in the second container at a speed sufficient to increase the temperature of the ferrous metal shot material in the vicinity of the surface so as to harden the ferrous metal shot material and form surface-hardened metal shot.
An air atomizing fluid spray gun designed for interchangeable use between gravity feed and pressure feed comprising a trigger; a body comprising a boss having first and second sides; a needle; a spray head rotatable between first and second generally diametrically opposed positions; and a fluid insert radially insertable into the spray head.
In an air spray gun comprising a longitudinal axis, a fluid nozzle, and an air cap having a pair of air horns, the improvement comprising said fluid nozzle extending through the air cap and comprising a frustoconical outer surface and a domed curving inner surface.
U.S. Patent 6,019,784. Feb. 1, 2000 R.A. Hines, assignor to Electroformed Stents Inc., Stillwell, Kan.
A process for producing a stent by electroforming comprising coating a mandrel with a resist; exposing portions of the resist to a light pattern so as to form a stent pattern on the mandrel; plating metal onto the mandrel so as to form a stent; and dissolving the mandrel.
