Abstract

<PICT:0720276/III/1> Benzoic, salicylic or a phthalic acid is vaporized in the still 10, being placed on the screen 14 and heated by the heater 18, immersed in water, or by steam admitted at 20. Air or nitrogen may also be introduced. Acid and water vapours are conducted through the conduit 24 and core 35 into the chamber 26, through which passes a conveyer 38 carrying razor blades to be treated with the vapours. The chamber 26 is connected by the conduit 28 to an evacuating pump.
