    • The invention concerns an electroplating plant comprising an electroplating container and a supply container between which the electrolyte circulates. In the supply container the metal content of the electrolyte is supplemented by a soluble anode which is associated with an auxiliary cathode located in an auxiliary catholyte which is separated from the electrolyte by a diaphragm which is impermeable to metallic ions. The insoluble anodes of the electroplating container are located in an auxiliary anolyte separated from the electrolyte by diaphragms which are impermeable to anions. The essential advantage of the invention is that insoluble anodes and necessary organic additives for the production of precision coatings, for example in the field of printed circuit boards, can also be used. According to a particularly advantageous development, the auxiliary catholyte and the auxiliary anolyte are guided in a common circuit such that opposed shifts in the pH value of the auxiliary catholyte and auxiliary anolyte are largely compensated as a result of their being continually mixed.
    • 本发明涉及一种包括电镀容器和供应容器的电镀设备,电解液在该供应容器之间循环。 在供给容器中,电解质的金属含量由可溶性阳极补充,该可溶性阳极与位于辅助阴极电解液中的辅助阴极相关联,辅助阴极电解液通过金属离子不可渗透的隔膜与电解液隔开。 电镀容器的不溶性阳极位于辅助阳极电解液中,电解液由阴极不可渗透的隔膜与电解液隔开。 本发明的主要优点是还可以使用不溶性阳极和用于生产精密涂层的必要有机添加剂,例如在印刷电路板领域。 根据一个特别有利的发展,辅助阴极电解液和辅助阳极电解液在共同的电路中被引导,使得辅助阴极电解液和辅助阳极电解液的pH值的相反变化由于它们连续混合而大部分被补偿。

    • A coin deposit lock for use in shopping trolleys has functional components which, when a coin is inserted into a slot, release the key retained in a key chamber which provides the coupling with the next trolley and vice versa. This function is obtained only because the inner shape of the housing and the outer shape of the functional components are matched in such a way that at least one functional component is freely movable in its own chamber between a locking and a release position. In particular, a control bolt is inserted in the housing which, when it moves between two end positions, controls the functional components of the coin slot and the key chamber in such a way that its outer side acts as a control cam for these functional components. Such a coin deposit lock can be made robust and reliable in a very simple manner with simple components and is inexpensive to produce and use.
