Abstract: Minicomputer including a computing unit, numeral, function and clearing inputs, a fixed-program memory and selectively freely-programmable memories, and a readout or display unit including a selector switch for calculating and converting in two systems of units selectively connectible to the fixed-program memory and the computing unit, the fixed-program memory having means for storing and reading out conversion factors and, selectively inverse values thereof as well as a corresponding dimension, the fixed-program memory having a respective input connected to a factor selection unit and to a call-up unit for the dimension of the respective selected factor and inverse value, and having a respective output connected to the computing unit and to the readout or display unit.

Abstract: PCT No. PCT/DE78/00024 Sec. 371 Date May 11, 1979 Sec. 102(e) Date May 11, 1979 PCT Filed Sept. 14, 1978 PCT Pub. No. WO79/00145 PCT Pub. Date Mar. 22, 1979Liquids with a very low conductivity are sterilized by means of anodic oxidation. For the purpose of increasing the conductivity without using chemically soluble additives, a gas which increases the conductivity, in particular CO.sub.2, is fed to the liquid before the anodic oxidation. For the purpose of carrying out the process, a device with an oxidation reactor (1) has a feed line (5), on the inlet side, for the gas to be fed in and a venting means (22) on the outlet side.

Abstract: A device for determining the blood sedimentation rate in a substantially vertical test tube, where the electrical or magnetic property of a given volume of liquid, which is changed by the settling of the erythrocytes in the test tube is measured as a function of time, by means of an oscillator with an output circuit which is completed via the column of liquid to be measured and by means of a measured-value pickup, having an output signal of which a pulse sequence of a definite frequency can be fed to a pulse counter with an indicating device.A coil-capacitor resonant circuit is coupled inductively with its coil or capacitively with its capacitor to liquid at a definite height in the test tube. An additional coil inductively coupled to the resonant-circuit coil serves as the measuring pickup. A retuning circuit is provided for the retuning of the resonance of the tuned L-C circuit which is detuned by the lowering of the boundary layer between the erythrocyte column and the plasma in the test tube.
