A linear attenuation equalizer and a method for designing such an equalizer using the cable attenuation curve to determine the D.C. attenuation and the lower or first corner frequency. The D.C. attenuation and the lower corner frequency are used to fix the design. A curve fit technique is used to determine the cable attenuation parameter which fixes the D.C. attenuation of the equalizer. The lower corner frequency is set at between about 10% and less than about 50% of the data rate, and preferably at approximately 20% of the data rate.

A multiple bore electromagnetic projectile launcher is provided with series circuit elements connected to the muzzle end of conductive rails of a bore to continue current conduction in those rails following the launch of a projectile and during the launch of a successive projectile. This current flow augments the flux in the successive bore during the launching of a successive projectile. Individual firing switches can be provided for each bore or additional conductive rails can be provided in an automatic switching arrangement to conduct current from a muzzle of a fired bore to the breech of a successive bore.

A filter connector for attentuating electromagnetic interference up to 1000 MHz having a housing, a filter element enclosed within the housing and electrically conductive pins mounted within the filter element. The filter element contains an alumina substrate with thick film layers of a metallization forming pin and ground electrodes, and a dielectric layer separating the electrodes screen printed over the substrate and a glass encapsulant. The ground electrode extends to the periphery of the substrate and is continuous except for clearance holes at the locations of pins.

An electromagnetic projectile launching system utilizes two cylindrical rail configurations. In one configuration, multiple conductive armatures are electromagnetically accelerated along rails which are located on the inner surface of a cylindrical barrel. The second configuration utilizes armatures located between concentric cylindrical rails. Rifling provides for spin stabilization of the projectile.

The conductivity of the laminations in an armature which conducts current between the launcher rails or switch rails of an electromagnetic propulsion system is graded such that uniform current density is achieved in each lamination. The conductivity of each lamination, which increases from the breech end to the muzzle end of the armature, is related to that of the lamination at the breech end by a single proportionality factor which is a function of the length of the armature in the direction of armature travel, the half-width of the gap between the rails, the velocity of the armature, the magnetic permeability of the rails, and the conductivity of the breech laminations and of the rails.
