Title: Investigation of air and water impurities - esp. very fine dust, using flameless atomic absorption spectroscopy
Inventor: KOENIG EBERHARD DR
IPC: G01N21/74
Filed: 1975-06-14
Abstract: A method of examining impurities (esp. very fine dust) in air and water uses flameless atomic absorption spectroscopy. The sample is continuously or intermittently applied to a moving carrier which is then passed through an analyser. The carrier is a strip of infinite length, not an endless belt. The carrier passes through a sampling device and is would onto a spool which can be removed from the appts. The strip can be inserted into a separate analyser continuously or discontinuously for analysis of the sample. Since the sampling device and analyser are independent, a single analyser can be used to serve a number of sampling points. Sample carriers can be exposed for long periods of time to increase the quantity of impurity collected.

Title: Slag deflector immersed in molten metal - to displace surface slag before a pipe is immersed in the metal
Inventor: KOCHANNECK UWE
IPC: B22D43/00
Filed: 1976-03-20
Abstract: The deflector consists of two half cone sections mating to form a conical shield below appts. which is immersed in the melt together with the deflector.
