Means for purifying waste gases

Claim 1

A DEVICE FOR PURIFYING EXHAUST GASES OF COMBUSTION ENGINES COMPRISING A HOUSING, AN EXHAUST PIPE ADAPTED TO BE CONNECTED TO THE EXHAUST SIDE OF THE ENGINE AND EXTENDING ALONG ONE SIDE OF THE HOUSING, AN EXHAUST TUBE CONNECTED TO THE EXHAUST PIPE AND EXTENDING HORIZONTALLY A SUBSTANTIAL DISTANCE INTO THE HOUSING, A PLURALITY OF OPENINGS FORMED IN THE BOTTOM SIDE OF THE EXHAUST TUBE FOR DIVIDING THE FLOW OF EXHAUST GASES RECEIVED FROM THE EXHAUST PIPE INTO A PLURALITY OF DOWNWARDLY DIRECTED STREAMS, A BODY OF EXHAUST GAS CLEANING FLUID CONTAINED IN THE HOUSING HAVING ITS SURFACE LOCATED A PREDETERMINED DISTANCE BENEATH THE BOTTOM SIDE OF THE EXHAUST TUBE, VALVE MEANS ASSOCIATED WITH THE EXHAUST PIPE CONTROLLING THE VELOCITY OF EXHAUST GASES ENTERING THE EXHAUST TUBE FROM THE EXHAUST PIPE, MEANS URGING SAID VALVE MEANS TO A CLOSED POSITION, THE EXHAUST GASES FLOWING IN THE EXHAUST PIPE VARYING IN VELOCITY AS A FUNCTION OF THE OPERATING CONDITIONS OF THE ENGINE, SAID VALVE MEANS BEING RESPONSIVE TO VARIATIONS IN THE VELOCITY OF THE EXHAUST GASES PASSING THROUGH THE EXHAUST PIPE AND OPENING AN AMOUNT WHICH IS A FUNCTION OF SAID VELOCITY SUCH THAT THE VELOCITY OF EXHAUST GASES PASSING THROUGH THE EXHAUST TUBE OPENINGS IS CONTROLLED BY SAID VALVE MEANS, AND MEANS FOR ADJUSTING THE SETTING OF SAID VALVE MEANS, AND MEANS FOR ADJUSTING THE SETTING OF SAID VALVE MEANS AS A FUNCTION OF THE OPERATING CHARACTERISTICS OF AN ENGINE WITH WHICH THE DEVICE IS ASSOCIATED.

Claim 2

A DEVICE FOR PURIFYING EXHAUST GASES OF COMBUSTION ENGINES COMPRISING A HOUSING, AN EXHAUST PIPE ADAPTED TO BE CONNECTED TO THE EXHAUST SIDE OF THE ENGINE AND EXTENDING ALONG ONE SIDE OF THE HOUSING, AN EXHAUST TUBE CONNECTED TO THE EXHAUST PIPE AND EXTENDING HORIZONTALLY A SUBSTANTIAL DISTANCE INTO THE HOUSING, A PLURALITY OF OPENINGS FORMED IN THE BOTTOM SIDE OF THE EXHAUST TUBE FOR DIVIDING THE FLOW OF EXHAUST GASES RECEIVED FROM THE EXHAUST PIPE INTO A PLURALITY OF DOWNWARDLY DIRECTED STREAMS, A BODY OF EXHAUST GAS CLEANING FLUID CONTAINED IN THE HOUSING HAVING ITS SURFACE LOCATED A PREDETERMINED DISTANCE BENEATH THE BOTTOM SIDE OF THE EXHAUST TUBE, VALVE MEANS ASSOCIATED WITH THE EXHAUST PIPE CONTROLLING THE VELOCITY OF EXHAUST GASES ENTERING THE EXHAUST TUBE FROM THE EXHAUST PIPE, MEANS URGING SAID VALVE MEANS TO A CLOSED POSITION, THE EXHAUST GASES FLOWING IN THE EXHAUST PIPE VARYING IN VELOCITY AS A FUNCTION OF THE OPERATING CONDITIONS OF THE ENGINE, SAID VALVE MEANS BEING RESPONSIVE TO VARIATIONS IN THE VELOCITY OF THE EXHAUST GASES PASSING THROUGH THE EXHAUST PIPE AND OPENING AN AMOUNT WHICH IS A FUNCTION OF SAID VELOCITY SUCH THAT THE VELOCITY OF EXHAUST GASES PASSING THROUGH THE EXHAUST TUBE OPENINGS IS CONTROLLED BY SAID VALVE MEANS, AND MEANS FOR ADJUSTING THE SETTING OF SAID VALVE MEANS, AND MEANS FOR ADJUSTING THE SETTING OF SAID VALVE MEANS AS A FUNCTION OF THE OPERATING CHARACTERISTICS OF AN ENGINE WITH WHICH THE DEVICE IS ASSOCIATED.
