Abstract: In order to create a process and a device for the monitoring and control of the flow of material in a hospital it is provided for the units generating the flow of material to each be provided with their own individual identification, for this individual identification to be read at various transit stations in the hospital, the read data of the individual identification and the transit stations to be fed to a central monitoring and control unit, stored and/or processed in it and for monitoring signals or control signals controlling the flow of material to be generated as a function of the stored and/or processed data.

Abstract: An instrument for surgical purposes has two relatively movable working parts and two relatively pivotable jaws interconnected in such a way that when they are opened, the two working parts are pushed together, whereby one of the two jaws has a shaft for the pivotable fitting of the other. The shaft is provided with regions of differing diameter and can be axially moved in such a way that selectively a larger or smaller-diameter region is effective in the region of the other jaw, which has a slot for the shaft with a narrower central section and broadened bearing sections at both ends. The width of the slot in the narrower central section lies between the diameter of the two regions of the shaft and has a diameter in the circularly broadened bearing sections corresponding to the larger diameter of the shaft.
