Ordinary is what the patent said, which is old fashioned for room temp. No other details were available from the text (the translation is 1:1), I presume that's because the authors took for granted everybody knew what the standard conditions of toluene sulphonation are, the invention doesn't directly relate to the production of tosic acid, but to the separation of the isomeres, the given example beeing a combination of both.
