摘要:
The invention relates to an improved process for the preparation of thioglycolic acid alkyl esters by heating a reaction mixture which essentially comprises thioglycolic acid, an alcohol and an acid catalyst, the water formed being removed by distillation using a water separator, in which the resulting product mixture is passed over a basic ion exchanger, if appropriate after removal of the acid catalyst.

The invention relates to a rotary printing press, particularly offset printing press, the printing unit of which comprises a printing form, a damping unit as well as an inking unit, said inking unit being provided with a set ink profile. In order to obtain a fast change of ink profile, it is proposed that, in order to eliminate the previous ink profile and to prepare the buildup of a new ink profile, the printing form 32 is inked over its entire surface area with the inking unit 1.
摘要:
A protective device for a feed unit, especially for a spindle sleeve of a measuring machine, whereby the feed unit is surrounded by a jacket constituted of a multiplicity of springs, which touch the feed unit in the event of a collision and thereby produce electrical contacts, and in which the lower or bottom part of the feed unit is enclosed by a protective shield. The protective shield is constituted of individual screen parts which are displaceable or swingable out of their inoperative position, and which collectively enclose the lower part, wherein the screen parts are maintained in their inoperative position by means of magnets, and in which the screen parts in their tilted position touch at least one spring and thereby become electrically contactive.
