Abstract: An electronic apparatus, process for its duplication, and arrangement for data transfer between two similarly constructed electronic apparatus is described in which the electronic apparatus has a microprocessor or microcontroller, a non-volatile memory, and an interface. The microprocessor or microcontroller, the non-volatile memory and other measures of the apparatus allow a data content of a certain memory component of a certain other apparatus to be simply transferred into the non-volatile memory. The apparatus thus has the ability to bequeath its data characteristics, or to duplicate itself. Further, a process is described for carrying out such a duplication. Assuming a second inventive electronic apparatus is built, a particular advantageous arrangement can be created in which a data record can be completely transferred from the memory of the first apparatus into the memory of the second apparatus. This data transfer is even beneficially possible when the second apparatus is partially defective.

Abstract: In a carding machine having cylinders, which are provided with a clothing of a saw-tooth wire helically wound thereon, carding elements are provided having saw-tooth wire sections, which are arranged at an acute angle to a plane that is transverse to the axis of rotation of the cylinders.
