Output energy indicating optical maser

Claim 1

IN AN OUTPUT ENERGY INDICATING OPTICAL MASER INSTRUMENT, A BALLISTIC TORSION BALANCE ARM, A PAIR OF REFLECTORS HAVING THEIR REFLECTING SURFACES FACING IN A PARALLEL RELATION WITH RESPECT TO EACH OTHER AND RIGIDLY SUSPENDED FROM OPPOSITE ENDS OF SAID BALANCE ARM RESPECTIVELY, MEANS FOR SUPPORTING SAID BALANCE ARM AT THE MIDPOINT THEREOF WHEREBY ROTATIONAL MOVEMENT IMPARTED TO SAID ARM MEMBER PRODUCES ROTATION ABOUT THE AXIS OF SYMMETRY OF SAID BALANCE ARM, A ROD-LIKE MASER ELEMENT ARRANGED IN PARALLEL RELATION WITH SAID BALANCE ARM BETWEEN THE REFLECTORS WHEREBY OUTGOING BEAMS FROM EACH END OF THE MASER ELEMENT ARE RESPECTIVELY DIRECTED ONTO THE REFLECTORS WHEN THE BALANCE ARM IS IN AN INITIAL POSITIOIN OF REST, SAID REFLECTORS BEING DISPOSED AT A 45* ANGLE WITH RESPECT TO THE BEAMS EMERGING FROM THE MASER ELEMENT SUCH THAT THE MASER BEAMS ARE REFLECTED IN OPPOSITE DIRECTIONS AND AT AN ANGLE OF 90* WITH RESPECT TO THE BEAMS IMPINGING THE REFLECTORS, THEREBY TO IMPART A MOMENT ABOUT THE AXIS OF SYMMETRY OF THE BALANCE ARM RELATIVE TO THE ENERGY OF THE BEAMS. A MIRROR HAVING A BEAM OF LIGHT FOCUSED THEREON CONNECTED TO SAID ARM AT THE MID-POINT THEREOF AND ROTATABLE THEREWITH, WHEREBY THE REFLECTION OF SAID BEAM OF LIGHT FROM SAID MIRROR IMPINGES UPON AN INDICATING SCALE INDICATING THE DEGREE OF ANGULAR MOVEMENT OF SAID BALANCE ARM FROM THE INITIAL POSITION OF REST.
