Abstract: A connector for connecting a container with a fluid preparation device for preparing a fluid, in particular a container with a concentrate for the preparation of dialysis fluid, as well as the combination of the connector, the corresponding container and the fluid preparation device. In order to simplify the handling during both the manufacturing process of such containers and the connection of such containers to the fluid preparation devices, the connector connects a first and second fluid line of the container with a third and fourth fluid line of the fluid preparation device with two laterally spaced-apart mounting elements which each incorporate one of two orifices terminating the first and second fluid lines.

Abstract: A container for use in dialysis, containing a certain amount of a salt concentrate in the form of a powder, granules or tablets or mixtures thereof, having an inlet for the water and an outlet that is connectable to a dialysis machine. Both the inlet and the outlet are situated on one side of the container, and each includes a filter therein to prevent any undissolved salt concentrate from leaving the container.

Abstract: The invention concerns a process for manufacturing a catalyst containing a carrier formed in major part of alumina and an active phase, the alumina carrier being obtained by admixing an alumina binding agent with a charge of alumina base.The process is characterized in that at least a portion of the active phase or of its precursor is introduced during the manufacture of the carrier so as to be present in the binding agent or in the charge before or during the admixture of the charge with the binding agent.The resultant catalyst may be used in reactions of hydrocarbons and carbon monoxide hydrogenation.
