  • Patent number: 5763736
    Abstract: A method for the decomposition of explosive materials into water-soluble products is offered, which can be disposed of in a thermal or biochemical way, which requires only very short reaction times because of the addition of polar, aliphatic, non-saponifiable compounds to a strongly basic, preferably aqueous reaction medium and under temperature control by means of the metered addition of the explosive materials.
    Type: Grant
    Filed: April 10, 1997
    Date of Patent: June 9, 1998
    Assignee: Oerlikon Contraves Pyrotec AG
    Inventor: Eduard Daume
  • Patent number: 4462312
    Abstract: In order to improve the incendiary effect of munitions the hollow compartment of a projectile body of a shattering and incendiary shell or grenade is provided with an incendiary charge and two explosive charges. The incendiary charge possesses at its rear region or end a substantially funnel-shaped recess or cavity into which there protrudes a substantially conically-shaped tip of the first explosive charge of said two explosive charges.
    Type: Grant
    Filed: June 2, 1982
    Date of Patent: July 31, 1984
    Assignee: Werkzeugmaschinenfabrik Oerlikon-Buhrle AG
    Inventors: Paul Cahannes, Eduard Daume, Jurg Sarbach
  • Patent number: 4402705
    Abstract: The incendiary mass comprises a zirconium or titanium powder containing a mean grain size of 15-50 .mu.m, to which there is added less than 2%-by-weight of an organic binder, in particular polyvinylacetate because small binder concentrations have a favorable effect upon the action or effect pattern of the combusting or burning metal particles, i.e. upon the combustion time and length of the flight trajectory.
    Type: Grant

    Date of Patent: September 6, 1983
    Assignee: Werkzeugmaschinenfabrik Oerlikon-Buhrle AG
    Inventors: Eduard Daume, Jurg Sarbach
  • Patent number: 4034676
    Abstract: An inhibitor coating for a solid propellant charge for protecting against undesired burning-off, comprising:A. an insulating layer containing a binder and a filler, andB. a protective- and adhesion layer located between the insulating layer and the propellant charge;C. the binder consisting of a castable mass which has poor smoke developing properties;D. the filler consisting of a fine granular cooling agent possessing good packability; andE. the protective- and adhesion layer consisting of a completely set polyisocyanate forming a barrier against plasticizer migration.
    Type: Grant

  • Patent number: 4021514
    Abstract: A method of producing an inhibitor coating for a solid propellent charge for protecting against undesired burning-off, the inhibitor coating containing an insulating layer composed of a binder and a filler, a protective- and adhesion layer located between the insulating layer and the propellent charge. The binder consists of a castable mass which has poor smoke developing properties, the filler of a fine granular cooling agent possessing good packability, the protective- and adhesion layer of a completely set or cured polyisocyanate forming a barrier against plasticizer migration. For the insulating layer there is initially admixed a pre-adduct with the cooling agent, and subsequently adding an aromatic diamine, an aliphatic plasticizer or an aliphatic polyol.
