Abstract: A process and an installation for utilizing organic substances are proposed, in which the substances are correspondingly comminuted and processed by mixing and reaction stages to utilizable compost.The installation essentially comprises a heatable fermenter with a stirrer located therein. In order to obtain an approximately closed process circuit the comminuted substances are supplied as so-called fresh material by a supply shaft to a conveying shaft constructed as a heat exchanger and undergo corresponding heating therein. Through further supply of fresh material the already heated fresh material is supplied to the fermenter and mixed therein by the stirrer accompanied by further heating.The fermented matter formed in the fermenter, on supplying further fresh material, can be admixed in a specific ratio as so-called bacterial inoculum with the fresh material throughout the process circuit.

Abstract: A blood pressure measuring appliance having a pulse beat detector responding to arterial pulse beats, an ECG signal detector and a time measuring apparatus which ascertains the time intervals between peaks of a predetermined type of the ECG signal detected by the ECG signal detector, preferably its R-peaks, and pulse beats in each case following the R-peaks and detected by the pulse beat detector. A display apparatus displays a datum representing the duration of the ascertained time intervals as blood pressure information. The blood pressure measuring appliance must merely be calibrated initially, for example, with the aid of a sphygmomanometer, in blood pressure values. The inflatable bag can be eliminated for further blood pressure measurements.
