Abstract: A powder-based core having an outboard end, for a gun ammunition projectile, comprising a compressed quantity of a first powdered metal having a first melting point and a first density, and a second powdered metal having a melting point lower than the melting point of said first metal and a second density which is less than the density of said first metal, and a quantity of said second metal in solid form integrally formed with said outboard end of said core. A projectile formed from the core is disclosed.

Abstract: A round of gun ammunition including a projectile adapted to be propelled from the gun at a subsonic velocity. The round includes a case containing a quantity of gun powder therein, but not filling the case. A projectile projects into the body portion of a case to a location proximate the gun powder. A disc having a circumference substantially matching the inner circumference of the body portion of the case at the level of the gun powder within the case is interposed between the gun powder and the proximal end of the projectile within the case to provide a barrier against movement of gun powder toward the open end of the case. In one embodiment, a further disc is interposed between the disc and the proximal end of the projectile to filter out gun powder particles which may escape past the barrier disc. A method for the manufacture of the round of gun ammunition is disclosed.

Abstract: This invention absorbs excess menstrual flow when an intra-vaginal tampon becomes saturated during periods of heavy flow. A system of two small-size soft absorbent cloths, placed externally in the user's crotch and held in place by the female anatomy, absorbs all the excess flow. First, the multi-layer Large Cloth Assembly, inserted between and held in place by the vaginal lips at the opening of the vagina, absorbs fluid which would otherwise run down the inside of the legs when the user stands. Second, the folded Small Cloth placed on the skin between the opening of the vagina and the anus, secured in place by the buttocks closing around it, absorbs fluid which would otherwise leak through the crack between the buttocks, particulary when the body is horizontal. Disposal of both cloths is by a toilet flush. The invention has been effective in clinical trials, is medically safe, simple and hidden from view, comfortable, low cost, and adapted to any anatomy.

Abstract: A method for the manufacture of a projectile for small-bore weapons ammunition comprising the steps of producing a compact from a mixture of a heavy metal powder and a light metal powder at room temperature, and without further treatment of the compact, introducing the compacts into a metal jacket, including pressing the compact into the jacket with a pressure sufficient to ensure substantially complete filling of a selected portion of the jacket by the compact. The compacts fill less that the entire volume of the jacket, leaving a portion of the jacket void of the compact. Prior to the pressing of the compact into the jacket, a disc having an outer diameter substantially equal to the internal diameter of said jacket adjacent the open end thereof is introduced into the jacket. Thereafter, that portion of the jacket adjacent its open end is infolded toward the longitudinal centerline of the jacket to at least substantially close the open end of the jacket.
