Hydraulic surface treating process and equipment

Claim 1

IN APPARATUS FOR HYDRAULIC BLASTING "REFORMING" OF SURFACES BY SURFACE REFORMING IMPACT WITH HARD BLASTING GRAINS HYDRAULICALLY JET IMPELLED AGAINST SAID SURFACE WITH SURFACE REFORMING VELOCITY AND KINETIC ENERGY, THE COMBINATION WHICH COMPRISES A TARGET AREA WHERE SAID SURFACE REFORMING IS TO BE EFFECTED, AN OPEN ENDED CONDUIT SPACED FROM SAID TARGET AREA AND DIRECTED THERETOWARD FOR CONDUCTING A HYDRAULIC BLASTING JET STREAM TO SAID TARGET AREA, A CONTAINER AROUND SAID CONDUIT AND SPACED ADJACENT ONE END THEREOF FORMING A RESERVOIR FOR MAINTAINING A SUPPLY OF SAID HARD BLASTING GRAINS AS A LIQUID SLURRY FOR ADMIXTURE IN A JET STREAM, HIGH VELOCITY AND HIGH PRESSURE LIQUID JET MEANS SPACED FROM AND DIRECTED INTO SAID CONDUIT FOR PROVIDING A HIGH VELOCITY HIGH PRESSURE LIQUID JET THROUGH SAID SUPPLY OF BLASTING GRAINS IN SAID RESERVOIR AND INTO SAID CONDUIT FOR ENTRAINING SAID BLASTING GRAINS IN SAID JET AND FOR IMPELLING SAID GRAINS THROUGH SAID CONDUIT AND AGAINST SAID SURFACE IN SAID TARGET AREA WITH SAID REFORMING VELOCITY AND KINETIC ENERGY FOR IMPINGING ON SAID SURFACE TO EFFECT SAID REFORMING THEREOF, AND MEANS FOR SUPPLYING SAID LIQUID TO SAID JET MEANS AT SAID HIGH PRESSURE FOR PROVIDING SAID HYDRAULIC BLASTING JET FLOW.
