    摘要: In a method and an apparatus for singling cards such as check cards or identity cards, each card to be singled is moved beforehand into a singling groove, thereby passing out of the area of a stop holding the stack. The card thus presingled is thereupon taken completely off the stack using a suitable removing sucker. In this way, cards can be singled very reliably and gently.

    摘要: An improved process for the preparation of polychloroprene by the emulsion (co)polymerization of chloroprene and optionally other monomers capable of copolymerization with chloroprene, using a peroxo activator, and subsequent working up of the product by stopping the reaction, stabilizing, degassing and isolating the product, characterized in that polymerization is carried out in the presence of dithiocarbamates and/or xanthates and 0 to 0.5% by weight of sodium .beta.-anthraquinone sulphonate.

    摘要: An improved polymerization and processing method allows the production of special nitrile rubbers which are characterized by a specific cation content which leads to an excellent storage stability and particularly good vulcanization rate and moreover results in vulcanized materials that have advantageous properties.
