Patent DE-2832043-A1 (DE)
Inventor: MELZER WERNER DIPL PHYS DR
IPC: G01N33/18
Filed: 1978-07-21
Abstract: For the quantitative determination of the total oxygen demand of water containing oxidizable matter, the water is continuously evaporated at about 900 DEG  C. in the presence of varying amounts l1, . . . , ln of oxygen-containing gas added per unit of steam at continuously repeated intervals. The oxygen-containing gas should not exceed 1 to 5% by volume, calculated on the amount of steam produced during each interval. The residual oxygen concentrations S1, . . . , Sn in the steam gas/mixture are measured for the different amounts of oxygen-containing gas added and the oxygen demand is calculated from the residual concentrations and the added amounts of the oxygen-containing gas.

Title: Laser measurement of surface peak to valley depths - using defocussed beam with variable angle of incidence suitable for soft metal coatings
Inventor: SELBACH GERD PROF DIPL ING
IPC: G01B11/30
Filed: 1978-12-04
Abstract: A contactless measurement device is for the peak to ralley depths of surfaces. It eliminates the problem of diamond point penetration into surfaces with soft metal coatings by using an optically defocussed laser beam projected onto the surface with a variable angle of incidence. A peak to valley depth-proportional, electronically-readable image is processed into an electrical signal which is calibrated w.r.t. a normal roughness to give a measurement accuracy better than 0.0001 millimetres. The variation of the angle of the emitted signal to the defocussing axis for constant focus gives a measure of the surface flow direction. The relative angle of incidence may be continuously varied to produce randomly distributed typical images suitable for on-line control of rolling processes.

Title: Data transmission method for text display - using TV receiver in which standard picture transmission lines are combined into data channels
Inventor: THOERNER GERHARD DIPL ING
IPC: H04N7/025
Filed: 1979-09-27
Abstract: The arrangement of data channels in one television channel is intended to make use of the existing picture construction, and be widely compatible with existing video text appts. Binary coded data is transmitted in data channels, each channel comprising 2 to power n lines of a standard half picture, where n is an integer. The proposed arrangement allows the setting up of data channels compatible with existing video text equipment, and also channels with a transmission rate of 64 kbits per second making use of more recent information services. Even higher rates can be accommodated if required in the future. Two lines per half frame gives the present standard rate of 32 kbits per second. The system can be operated simultaneously with data channels using differing numbers of lines.
