    • The invention relates to a pressure plate arrangement for joining together a plurality of material webs each comprising at least one plain web and/or at least one corrugated web, to form a corrugated cardboard web (P), at least one of the material webs being provided with adhesive at least in sections. The arrangement comprises a contact pressure unit (14) provided with a pressure plate (22), and a heatable counterpressure plate (26), between which the material webs being joined together are passed. The contact pressure unit (14) and the pressure plate (22) are arranged to be approachable to or removable from the counterpressure plate (26), wherein the pressure plate (22) is also constructed to be heatable. The invention also relates to apparatus for joining together a plurality of material webs comprising a plurality of such pressure plate arrangements.

    • In an apparatus for the discontinuous dosing of a constant quantity of fluid into an analysis device, the fluid feed system is connected by means of a three-way valve on the one hand via the dosing valve and a shut off valve arranged downstream and on the other hand via a by-pass to the fluid discharge system. A compressed air source for the production of a constant air pressure is connected between the three-way valve and the dosing valve. All the components of the system are controlled by a programme control unit, so that the fluid flow through the dosing valve is temporarily interrupted by closing the shut off valve and switching over the fluid feed to the by-pass and at the same time releasing the connection of the compressed air to the dosing valve. Thereafter the compressed air source is switched off by the control unit and the interruption of the fluid flow at the dosing valve is cancelled.
    • 在用于将恒定量的流体不连续地分配到分析装置中的装置中,流体供给系统通过三通阀一方面经由计量阀连接,另一方面通过排列在下游的截止阀 另一方面通过旁路流体排放系统。 用于产生恒定气压的压缩空气源连接在三通阀和计量阀之间。 系统的所有组件由程序控制单元控制,从而通过关闭截止阀并将流体进给切换到旁路而临时中断通过计量阀的流体流动,同时释放 将压缩空气连接到计量阀。 此后,通过控制单元关闭压缩空气源,并取消计量阀处的流体流动的中断。
