  • Patent number: 10843979
    Abstract: A method of manufacturing a multi-layered propellant grain is provided. The method of the present disclosure simplifies the setup necessary to produce multi-layered propellants by using industrial equipment that is more energy and space efficient than the machinery that is conventionally employed for such processes. The method comprises providing a first propellant formulation; providing a die configured to provide a structure having an outer shell and a hollow interior when material is extruded therethrough; extruding the first propellant formulation through said die, to produce a first propellant layer having an outer shell defining a hollow interior in the form channel having open ends; providing a second propellant formulation, said second propellant formulation being of low viscosity; injecting said second propellant formulation into said channel defined by said first propellant layer to form a second propellant layer disposed in said channel; and hardening said second propellant layer.

  • Publication number: 20150143615
    Abstract: A sweat collector for wearing on a user's head to collect sweat from the user's head and prevent the collected sweat from running into the user's eyes. The sweat collector is at least partly made of nonabsorbent material. The sweat collector comprises a sweat-collecting recess between its inner and outer sides for collecting sweat. The sweat-collecting recess may be configured to retain the collected sweat by surface tension and adhesion. Other types of sweat collectors for collecting sweat from other body parts (e.g., a forearm) are considered. Other types of liquid collectors for collecting liquid other than sweat are considered (e.g., water on a user's head or other body part originating from a bath, pool or other external source; bottled liquid; etc.).

  • Patent number: 8257522
    Abstract: Propellant compositions are provided herein for use in small arms cartridges. Such propellant compositions include a cellulose-based organic fuel, a non-azide, nitrogen-containing primary organic oxidizer and a secondary nitrate, perchlorate, chlorate of peroxide oxidizer. Preferably, such compositions are in the form of extruded shaped hollow cylindrical grains having dimensions that makes it loadable in a muzzleloader firearm or small calibre firearm cartridge case. Ignition grains are also provided for use alone or in a mixture with the propellant compositions. When used in a small calibre firearm or muzzleloader, the temperature of combustion is at a level that ensures substantially complete combustion of the fuel during firing so that the products of combustion are mostly gaseous.

  • Patent number: 8133335
    Abstract: Propellant compositions are provided herein for use in small arms cartridges. Such propellant compositions include from about 70 to about 90% by weight of a cellulose-based organic fuel, from about 5 to about 30% by weight of a non-azide, nitrogen-containing primary organic oxidizer and from about 0.5 to about 10.0% by weight of a secondary nitrate, perchlorate, chlorate or peroxide oxidizer. Preferably, such compositions are in the form of extruded shaped hollow cylindrical grains having a length in the range of 0.030 to 0.200 inch, a diameter in the range 0.040 to 0.070 inch, and having a coaxial opening there through having a wall grain thickness in the range 0.008 to 0.016 inch. Ignition grains are also provided for use alone or in a mixture with the propellant compositions. When used in a small caliber firearm or muzzleloader, the temperature of combustion is at a level that ensures substantially complete combustion of the fuel during firing so that the products of combustion are mostly gaseous.
