Abstract: A method for burning fuels, particularly garbage, in incinerators with a stoker grate, for which the primary air is supplied below the stoker grate into the fuel layer and the secondary air is supplied above the fuel layer, is controlled in such a way that the intensity of the combustion of the fuel on the stoker grate is increased by increasing the oxygen content of the primary air and the intensity of the combustion in the secondary combustion zone is choked by decreasing the oxygen content in the secondary air. Flue gas, preferably from the combustion process, is recirculated in order to reduce the oxygen content of the secondary air.

Abstract: A filter for the purification of tap water containing several layers of different filter materials. One of the layers is an adsorption filter element comprising a self-supporting sintered body of finely dispersed adsortion material, e.g., activated charcoal, a thermoplastic binder material and a finely dispersed, oligodynamic material, wherein these materials provide a fine-mesh, mechanical filter. The adsorption filter can also be used by itself for filtering purposes.

Abstract: A warhead which is deliverable through the intermediary of a carrier, and which incorporates aerodynamic guiding and braking media and forwardly oriented striking pins for initiating a detonating information for an explosive which is contained or dammed by a hollow-cylindrical wall structure with shallow-concavely curved coverings. The coverings are designed for a fragmentation angle which increases upwardly from below along their projectile directions of flight or trajectories, and in which a firing and pin is imparted a responding threshold which leads to the initiation of the detonating information only under a relatively hard impact.

Abstract: An active component of submunition for utilization from a carrier against different target objects, especially against semi-hard and hard or heavily armored target objects; as well as warheads for this purpose and flechettes which are preferably deployed over the targets through the intermediary of such warheads. The active component incorporates at least one warhead having flechettes, which is equipped with a propellant or propulsion mechanism for the acceleration of the warhead in the direction of effect for the flechettes, and with an ejector piston for additional acceleration of the flechettes through the ejection from the precedingly accelerated warhead.
