Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
156 words
THE COMBINATION OF A MAGNETIC SUSPENSION SYSTEM AND POWER SUPPLY TRANSFORMER FOR A BODY WHICH IS ROTATABLE ABOUT A PREDETERMINED AXIS COMPRISING FIRST AND SECOND ELECTROMAGNETS, THE ELECTROMAGNETS INCLUDING RESPECTIVE COILS DISPOSED NORMAL TO AND COAXIAL WITH THE PREDETERMINED AXIS, A BODY FREELY SUSPENDED BETWEEN THE ELECTROMAGNETS AND INCLUDING FIRST AND SECOND MAGNETIC ARMATURES DISPOSED IN MAGNETIC PROXIMITY TO THE FIRST AND SECOND ELECTROMAGNETS RESPECTIVELY, A SOURCE OF ALTERNATING VOLTAGE CONNECTED WITH EACH ELECTROMAGNET FOR EXCITATION THEREOF WHEREBY THE BODY IS SUSPENDED BY THE ATTRACTIVE MAGNETIC FORCES BETWEEN THE ARMATURES AND THE RESPECTIVE ELECTROMAGNETS, A SECONDARY COIL DISPOSED ON THE BODY COAXIALLY ADJACENT ONE OF THE ELECTROMAGNET COILS AND SPACED THEREFROM, MEANS TO DEFINE A MAGNETIC CIRCUIT BETWEEN SAID ONE ELECTROMAGNET COIL AND THE SECONDARY COIL THEREBY TO TRANSFER ELECTRICAL ENERGY BETWEEN THE COILS, ELECTRICAL LOAD MEANS CARRIED BY THE BODY, AND OUTPUT CIRCUIT MEANS CONNECTING THE SECONDARY COIL WITH THE ELECTRICAL LOAD FOR ENERGIZATION. THEREOF.
