Klaus-Achim Kratzsch has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9016203
    Abstract: The invention relates to producing a propellant charge igniter tube (2) for a propellant charge igniter (1) by means of hydroforming (high-pressure forming). According to the present invention, a sleeve base (6) is then joined to the propellant charge igniter tube (2) by means of friction welding, for example, and vulcanized without reworking. In this context, the rubber lips of the sleeve base (6) and the propellant charge igniter tube (2) are molded on, or vulcanized, on in one operation. The vacuum-packed benites (8) and the lower part (9) of the propellant charge igniter (1) can then be mounted in the sleeve base (6).

  • Patent number: 8516964
    Abstract: The invention relates to a cartridge having a propellant charge casing at least partially filled with a propellant charge powder, and a projectile part connected on a front of the propellant charge casing, wherein the propellant charge casing comprises a casing cover, a casing sheath and a casing base, and the casing sheath is connected to the projectile part via the casing cover and to the casing base via a spring steel sheet. In order to achieve different amounts of propellant charge powder filled into the same propellant charge casing without igniting the propellant charge at undesirable blast waves, a sack-shaped container that is completely filled with the respective amount of propellant charge powder is disposed inside the propellant charge casing so that the container, and thus also the propellant charge powder, extends in the direction of the central longitudinal axis of the cartridge.
