Abstract: In a process for quantitative determn. of halohydrocarbon cpds. (I), esp. vinyl chloride in gases, a measured amt. of the gas is heated to 300-600 degrees C in the presence of steam and catalysts.

The appts. used consists of an inlet tube for the gas stream mounted concentrically inside an outer tube. A heating spiral of Pt or Pt alloy is wound round the outside of the inner gas inlet tube, over which the gas stream in the outer tube flows. The heating spiral is run at a temp. of >=700 degrees C esp. is approx. 750 degrees C to give an average operating temp. of 550-650 degrees C. Process allows continuous automatic monitoring of vinyl chloride content of gas streams and can be used e.g. to trip a warning signal if the vinyl chloride concn. rises above a predetermined level.

Patent NL-8401796-A (NL)
IPC: C02F9/00
Filed: 1984-06-05
Abstract: Iron is recovered from an iron containing dust obtained in processing iron or steel by dissolving iron and bivalent metals being present in said dust in an acid. Subsequently the iron is precipitated by adding an alkaline substance or ammonia to adjust the pH to 5 to 8. Before or during precipitating the iron the bivalent ions as present such as zinc, cadmium and lead are converted into a soluble complex by means of a complexing agent. Preferred complexing agents are polyamines, particularly triethylene tetramine being an excellent complexing agent for zinc. The precipitated iron hydroxide is recovered and may be reused. The process may be separated more than once in the same solution, thereby providing a final solution containing considerable amounts of zinc, cadmium, or other bivalent metals which may be separated by boiling or precipitation. The complexing agent may be recovered by destillation after having made the complexes strongly alkaline or by precipitation by adjusting the pH to 1 and recovering the salt of the complexing agent such as a hydrochloric acid salt of the complexing agent.

Title: Method and device for non-contact measuring of distances
IPC: G01S17/32
Filed: 1991-10-30
Abstract: In a method for non-contact measuring of a distance between an optical sensor and an object, an electromagnetic wave being used to focus on the surface of the object, the distance from the focusing point to a point on the surface of the object is varied in accordance with a prescribed pattern, while focusing on the surface of the object at a number of successive instances. The foreknown pattern and the time elapsed between the respective instances provide the data for calculating the distance in question. The options include those of altering the position of the object in accordance with the pattern or altering the position of the sensor or alternatively altering the focal length, which is done, for example, by altering the frequency of the wave or, for example, by altering the position of the wave source or of a focusing lens in the sensor.
