Title: Monitoring contaminated water streams - to determine the content of oil using fluorescent radiation
Inventor: DEVIAL RAYMOND MICHAEL
IPC: G01N21/64
Filed: 1977-10-19
Abstract: A water stream is continuously monitored to measure its oil contamination content. Fluorescent radiation is continuously directed at the stream as it passes a monitoring point and a signal is produced proportional to the oil contamination present. Discrete samples are continuously withdrawn from the stream and the degree of oil contamination of the samples is measured using an infra-red absorption procedure. This comprises adding a solvent to separate from the water a solution of oil in the solvent. The infra-red absorption capability of the percentage of oil in the solvent is measured and the result is used to recurrently recalibrate the signal produced by the continuous monitoring process.

Patent DE-2845887-A1 (DE)
Title: Optical light guide mfr. - by shrinking outer plastic sheath on plastic hose surrounding optical light guide fibre
Inventor: SCHLANG PETER DIPL ING
IPC: B29D11/00
Filed: 1978-10-21
Abstract: An optical light guide assembly is produced by surrounding the optical light fibre by a plastic hose, e.g. of polyethylene, with a bore slightly larger than the outer dia. of the fibre. This is done either by extruding the hose around the fibre or by slitting a hose and inserting the fibre. An outer sheath e.g. of polyethylene, is now extruded on this assembly in such a way that the sheath shrinkage during the cooling period causes the plastic hose to be upset by a certain amt. which is governed by a formula quoted in the Patent. When such a light guide is wound on a cable drum, the length difference between the plastic hose and the light guide fibre ensures that the fibre elongation does not exceed 0.5% because more would lead to brittle fatigue fractures. Nor does the compression exceed 0.8%, because more would lead to microbendings and to intensified attenuation.

Title: Communications system carrier frequency keying circuit - connects line to threshold detector reversing current source polarity depending on detector setting for capacitor charging
Inventor: MAGERL JOHANN ING GRAD
IPC: H04J1/14
Filed: 1978-11-08
Abstract: Communication system has circuit elements for keying in an outer band signal frequency into the transmission channel of a carrier frequency channel converter. It uses a direct current signal in the form of earth or not-earth which is converted into an outer band signal frequency. The signal elements consist of integrated circuit modules. The signal line is connected to a threshold value detector (D) where the signal is evaluated. A current source (2) is connected to the detector, where the polarity of the current source will be reversed depending on the evaluation criterion of the detector. This will decide whether a capacitor (C) will be charged or discharged via two diodes connected in parallel with polarities reversed. The voltage from the capacitor is fed into a modulator (M) which will convert the signal achieved in this manner in the HF signals.

Inventor: HOELL WOLFGANG DIPL ING DR
IPC: B01J49/14
Filed: 1978-11-25
Abstract: Anion exchangers, used to remove the anions of strong acids from crude waters, are regenerated in HCO3- form from aq. suspensions, by simultaneously using a solid Ca cpd. and gaseous CO2, separating the ion exchanger from the regenerated after regeneration and returning the ion exchanger for re-use. Novelty comprises (a) using CaCO3 as the Ca cpd., in a quantity above that limited by CaCO3 dissolution rate and regenerating process duration; (b) effecting regeneration in a system having constant HCO3 ion concn. and (c) introducing the CO2 at a CO2 partial pressure above the ion exchanger aq. suspension of 5 x 10-3 to 1 (pref. 0.01-0.2) MPa and maintaining this partial pressure during the regeneration process. Ion exchanger conversion to the free base form during regeneration is avoided. High recovery of exchanger capacity, e.g. 30-50% is achieved economically. The process causes no environmental pollution.
