    摘要: A process for preparing 1-aminoanthraquinone, comprising the steps of:A. reacting o-chloromethylphenylisocyanate with at least an equivalent amount of benzene in anhydrous hydrofluoric acid at a temperature of about -10.degree. to 200.degree. C to form the lactam of 2-amino-diphenylmethane-2'-carboxylic acid,B. saponifying the lactam of 2-amino-diphenylmethane-2'-carboxylic acid with aqueous alkali at a temperature above about 100.degree. C to form the 2-amino-diphenylmethane-2'-carboxylic acid,C. contacting the 2-amino-diphenylmethane-2'-carboxylic acid with an acid condensation agent, thereby to convert the carboxylic acid to 4-amino-anthrone, andD. contacting the 4-aminoanthrone with an oxidizing agent in an acid or alkaline medium, thereby to convert the aminoanthrone to 1-aminoanthraquinone. Special conditions are also recited for carrying out the individual steps to obtain high yields.

    摘要: A rotary tool for drilling and chamfering, which takes place in one common advance, essentially comprises a base body, a drill clamped centered therein and a chamfering tool disposed on the end of the base body toward the drill tip and having a cutter body tip disposed next to the flank of the lateral free face of the drill. The chamfering tool can be radially adjusted in relation to the drill in a direction pointing at right angles in respect to the drill axis.

    摘要: A gearing is described for locks of panic doors. The gearing has a first gearing part (17)which is rotatable around a first axis (17a) and can be connected with an actuating member (18) for a lock nut or the like, and a second gearing part (28) which is rotatable around a second axis perpendicular to the first axis and is connected with a handle (1). One of the gear parts is provided with a driver pin (24) arranged parallel to and at a distance from the first axis and the other gearing part is provided with a guide part cooperating with the latter for the purpose of converting the rotating movement of the handle (1) into a rotating movement of the actuating member (18).
