3. IN MAGNETIC LIFTING APPARATUS FOR MOVING MAGNETIC LOADS AND BEING OPERATIVE WITH A SOURCE OF CONTROL SIGNALS, THE COMBINATION OF:
- A PERMANENT MAGNETIC FLUX TRANSFER DEVICE INCLUDING A PERMANENT MAGNET FOR SUPPLYING MAGNETIC FLUX, A PAIR OF POLE MEMBERS, SAID PERMANENT MAGNET BEING DISPOSED BETWEEN SAID PAIR OF POLE MEMBERS FOR PROVIDING A FIRST AND A SECOND MAGNETIC CIRCUIT RESPECTIVELY THROUGH A LOAD AND A KEEPER END OF SAID DEVICE, WITH THE MAGNETIC FLUX DIVIDING BETWEEN SAID MAGNETIC CIRCUITS ACCORDING TO THEIR RELATIVE RELUCTANCE, AND A CONTROL WINDING DISPOSED IN AT LEAST ONE OF SAID MAGNETIC CIRCUITS FOR CONTROLLING THE RELUCTANCE THEREOF IN RESPONSE TO CONTROL SIGNALS BEING APPLIED THERETO;
SAID LOAD DISPOSED FOR MOVING AT SAID LOAD END OF SAID MAGNETIC DEVICE IN SAID FIRST MAGNETIC CIRCUIT WITH A LOAD AIR GAP BEING FORMED BETWEEN SAID LOAD AND SAID POLE PIECES AT SAID LOAD END OF SAID DEVICE;
A KEEPER MEMBER MOVABLY DISPOSED AT SAID KEEPER END OF SAID MAGNETIC DEVICE, WITH A KEEPER AIR GAP BEING FORMED BETWEEN SAID KEEPER MEMBER AND THE POLE PIECES AT SAID KEEPER END OF SAID DEVICE;
AND SAFETY MEANS CONNECTED TO SAID DEVICE TO PREVENT THE INADVERTENT DROPPING OF SAID LOAD;
SAID APPARATUS OPERATIVE FOR MOVING SAID LOAD BY DISPOSING SAID LOAD AND SAID KEEPER MEMBERS ADJACENT SAID LOAD
