Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
138 words
A METHOD OF WETTING A METAL SURFACE WITH A MOLTED METAL COMPRISING THE STEPS OF: TORSIONALLY VIBRATING AN ELASTIC COLUMN PRODUCING A STANDING WAVE VIBRATION AT THE RESONATE FREQUENCY THEREOF CAUSING ALTERNATING TORSIONAL DEFLECTIONS TO OCCUR AT OPPOSITE ENDS OF SAID COLUMN, THE DEFLECTION AT ONE END BEING GENERALLY 180 DEGREES OUT OF PHASE WITH THE DEFLECTION AT THE OTHER END AT THE RESONATE FREQUENCY, SUPPORTING SAID COLUMN AT THE NODAL POINT WHERE TORSIONAL DEFLECTION IS AT A MINIMUM, SUPPORTING A METAL BODY AT ONE END OF THE COLUMN SO THAT IT RECEIVES OSCILLATORY EXCITATIONS THEREFROM, PLACING SAID BODY WHILE IN SAID OSCILLATING CONDITION IN A CONTAINER, AND INTRODUCING MOLTEN METAL INTO THE CONTAINER TO MECHANICALLY ATTACK AND WET THE SURFACES OF SAID BODY AS A RESULT OF THE SHEARING ACTION BETWEEN THE MOLTEN METAL AND BODY SURFACES.

Claim 3
Dependent Claim
116 words
SONIC VIBRATORY APPARATUS FOR WETTING THE SURFACE OF A FERROUS METAL ARTICLE LOCATED IN A BATH OF MOLTEN NON-FERROUS METAL, COMPRISING AN ELASTIC MEMBER, VIBRATION GENERATING MEANS CONNECTED TO SAID ELASTIC MEMBER, A SOURCE OF COMPRESSED AIR FOR DRIVING SAID VIBRATION GENERATING MEANS AT A RESONANT STANDING WAVE FREQUENCY OF SAID ELASTIC MEMBER SO AS TO ESTABLISH AT LEAST ONE NODAL POINT AND ONE ANTINODAL POINT ALONG SAID MEMBER, A COUPLING MEMBER EXTENDING FROM SAID ELASTIC MEMBER AT AN ANTINODAL POINT THEREOF, AND MEANS FOR SUPPORTING SAID ELASTIC MEMBER SO THAT SAID COUPLING MEMBER IS LOCATED IN SAID BATH FOR DELIVERING HIGH FREQUENCY VIBRATORY ENERGY TO THE MOLTEN NON-FERROUS METAL ADJACENT SAID SURFACE OF SAID ARTICLE.
