Abstract
Abstract IN ORDER TO CONTROL THE INIFORMITY OF VAPOR EMISSION AND TO MAXIMIZE THE TIME DURING WHICH AN EFFECTIVE AMOUNT OF VAPOR EMISSION OCCURS, AN ABSORBENT BODY IS IMPREGNATED WITH VAPORIZABLE MATERIAL AND IS COMPLETELY SURROUNDED BY A VAPOR-PERMEABLE PLASTIC SHEATH WHICH DOES NOT ENTER INTO A SOLUBILITY RELATIONSHIP WITH THE VAPORIZED MATERIAL AND THEREFORE CONTROLS THE RATE OF VAPOR EMISSION.
