Title: Light Emitting Rigid, Fracturable Projectile-Type Marking Ammunition and Electronic Strobe Flash Apparatus for Air Powered Guns
Inventor: CHENG RICHARD T
IPC: F41B11/00
Filed: 1996-06-06
Abstract: Light emitting rigid, fracturable projectile-type marking ammunition and an electronic strobe flash apparatus for use with air powered guns are provided.  The marking ammunition is in the form of a phosphorus paintball.  The electronic strobe flash apparatus comprises an exciter adaptable for use with paintball guns for exciting the phosphorus paintball to emit light.  The exciter couples to the muzzle of a paintball gun.          The light emitting paintball provides a luminous trail when discharged from the paintball gun.   A paintball according to the instant invention comprises a spherical pellet or capsule defining an interior chamber,  and a filler contained in the chamber.  In one embodiment, the capsule is impregnated with a phosphorescent  material.    In  an  alternative  embodiment,  a phosphorescent  material  is  mixed  with  the  filler. The phosphorus material  absorbs  light when  exposed  to  a  light source, and after the light source is removed, emits light.  A paintball   being  discharged from a paintball gun enters the exciter.   Upon detecting the presence of a paintball,  the exciter is triggered to produce a high intensity light.  Light is absorbed by the phosphorescent material.   After the light is removed, the phosphorus material continues to emit light.          Paintballs  according  to  the instant  invention  discharged through the exciter provide a luminous trail  and thus, may be used effectively in the dark.

Title: Helical embolization coil
Inventor: TEKULVE KURT J
IPC: A61B17/12
Filed: 1995-03-16
Abstract: A conically helically shaped embolization coil (10) for occlud-ing a blood vessel, aneurysm, and the like. The embolization coil includes a continuous platinum-tungsten alloy wire strand (11) wound into a longitudinally ex-tending coil (12) having a plural-ity of tightly spaced turns (13). The longitudinally extending coil is wound into a conically helically shaped coil (15) with a plurality of radially expanding turns (16) that has spacing that increases proxi-mally from the distal end (29) of the coil. Distal turn (17) of the ra-dially expanding turns has a minor diameter (18) less than a minimum diameter (34) of a vessel (32) of which the embolization is to be positioned therein. Uncompressed proximal turn (19) of the radially expanding turns has a major diameter (20) greater than a maximum diameter (33) of the vessel in which the coil to be positioned. The conically helically shaped coil and particular diameter ensure that the coil is precisely positioned in a vessel lumen without longitudinal displacement of the delivery catheter. The coil is stress relieved and, in particular, heat treated by heating the coil to a stress relief temperature of the continuous wire strand and cooled to relieve residual stresses formed during the winding of the coil and to minimize the formation of new residual stresses formed during the cool down period of the heat treatment. Thrombogenic fibers (26) are positioned in the tightly spaced turns of the coil to attract thrombus and build up a mass that occludes the vessel lumen.

Abstract: A hydrometallurgic and electrochemical process for processing sulfur antimony ores and residues is disclosed,   the   end  products   from  which   are electrolytic antimony and elemental sulfur.     The concentrate of sulfur antimony ore, leached with a solution of caustic alkali according to the known techniques dissolves, as sulfur salts as much Sb as possible, whilst the other heavy and precious metals  which  accompany  the  antimony  bearing  ore remain unchanged in the residue.     From the solution of antimony sulfur salts pure Sb2S3  is  precipitated  by  acidification  and  this sulfide, separated from the solution by filtration, is  leached  with  a  ferric  fluoborate      based electrolyte which oxidizes  sulfide  into  elemental sulfur and dissolves antimony as Sb3+ fluoborate.     The resulting mixture is filtered once more in order to separate elemental sulfur and the solution of Sb fluoborate is submitted to electrolysis in a diaphragm cell with electrolytic Sb being obtained at the cathodes, and regenerated ferric fluoborate being recycled to the step of Sb2S3 leaching in the anodic compartment.
