Abstract
Abstract A magnetic weapon link transducer transfers both power and option information signals from an ordnance delivery vehicle to an ordnance device. The transducer includes a plurality of magnetic cores of diverse diameters located in excitation and load units, respectively. Airgaps, which may be of diverse thicknesses, separate corresponding cores on the excitation and load units. Individual AC and RF shields are included to insure that only concurrent excitation of the transducer and weapon release will transfer the power and information signals from the delivery vehicle to the ordnance device.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
158 words
A magnetic weapon link transducer comprising an excitation core unit including a plurality of magnetizable cores located therein, a load core unit mechanically separable from said excitation unit and including a plurality of magnetizable cores located therein and corresponding to said magnetizable cores located in said excitation unit, means for biasing said excitation core unit and said load core unit in a continuous relationship, shorting turn means individual to each of said plurality magnetizable cores located in said excitation unit for shielding said magnetizable cores from AC signals, coil form means individual to each of said plurality of magnetizable cores located in said excitation unit and in said load unit for shielding said magnetizable cores from RF signals, first winding means connectable to a source of excitation signals, and second winding means connectable to a load for transferring said excitation signals upon concurrent excitation of said first winding and relative movement of said excitation and load core units.
Claim 2
Dependent Claim
158 words
