Claims

3. MOTION PICTURE PROJECTION APPARATUS COMPRISING:

A PLURALITY OF MOTION PICTURE PROJECTORS DIRECTED TOWARD ADJACENT SCREENS SO THAT THEIR INDIVIDUAL PICTURES MAY BE COMBINED INTO A PANORAMIC VIEW;

A SELF-SYNCHRONOUS RECEIVER MOTOR DRIVING EACH OF SAID PROJECTORS;

A COMMON SELF-SYNCHRONOUS TRANSMITTER FOR SAID RECEIVER MOTORS;

MEANS FOR ELECTRICALLY CONNECTING AND DISCONNECTING SAID RECEIVER MOTOR TO SAID TRANSMITTER;

MEANS FOR APPLYING REDUCED ENERGIZATION TO SAID TRANSMITTER WHILE IT IS AT REST TO BRING THE RECEIVER MOTOR ROTORS TO THEIR NULL POINTS UNDER REDUCED TORQUE;

MEANS FOR APPLYING FULL ENERGIZATION TO SAID TRANSMITTER AFTER RECEIVER MOTOR ROTORS ARE POSITIONED ADJACENT TO THEIR NULL POINTS;

MEANS FOR ROTATING SAID TRANSMITTER AT A PREDETERMINED SPEED TO EFFECT SYNCHRONOUS ROTATION OF TLHE PROJECTOR DRIVING RECEIVER MOTORS THEREWITH SO THAT THE INDIVDUALLY PROJECTED PICTURES WILL COMBINE INTO A PANORAMIC SCENE;

AND MEANS PREVENTING THE ELECTRICAL CONNECTION OF A RECEIVER MOTOR TO THE TRANSMITTER WHILE THE TRANSMITTER IS FULLY ENERGIZED SO AS TO PREVENT THE PULLING OF A RECEIVER MOTOR ROTOR INTO SYNCHRONOUS LOCK UNDER FULL TORQUE.
