Apparatus for advancing strands

A machine for labeling containers around their complete circumference. The machine has a driven rotating turntable with rotating plates that are positioned around its circumference. The plates accommodate the containers and, as they travel past a labeling station, are rotated at different individual speeds by means of a drive mechanism. The drive mechanism includes roller cams and a recessed cam in order to adapt to the cross-sections of the different containers. In order to provide a machine for labeling containers around their complete circumference in which the specific speed of the rotating plates can be considerably more rapidly and easily adapted to the cross-section of the containers being labeled, one section of the recessed cam consists of cam elements that are positioned at intervals, that are designed to yield, and that are adjustably supported.

The invention relates to a selective hydrogenation method for a C2 fraction. In the method, a front hydrogenation process method with front deethanization is employed, wherein a material flow discharged from the top of a front deethanizing column in an ethylene apparatus is fed into a fixed bed reactor to perform the selective hydrogenation. A Pd-Ni-series catalyst is arranged in an adiabatic bed reactor. During preparation of the catalyst, an alumina-series carrier is combined with a bipyridine derivative having a hydroxyl group, wherein a metal complex is formed from the hydroxyl bipyridine derivative combined with the carrier and an active component. The method greatly improves activity and selectivity of the hydrogenation reaction, reduces generation amount of green oil, prolongs service life of the catalyst, ensures qualified hydrogenation on the acetylene, and improves the stability of operation in the apparatus. The catalyst has excellent impurity interference resistance and CO fluctuation resistance, and is especially suitable for a C2 front-hydrogenation apparatus being high in impurity contents such as sulfur and arsenic, and can reduces the influence on the apparatus due to temperature runaway.
