Title: Gamma radiation detector with adjustable characteristic - has energy band detectors with weighted output to summing circuit
Inventor: GEHM ULRICH DIPL PHYS
IPC: G01T1/20
Filed: 1975-09-24
Abstract: The gamma ray dosimeter uses a sodium iodine crystal detector connected to a photomultiplier. The output of the photo-multiplier is amplified and the amplifier output is connected to a number of amplitidue discriminators. Each discriminator responds to a given energy range and produces an output pulse of definite duration and amplitude each time the detected gamma energy falls within its range. The output of each discriminator is connected to the input of weighting circuits. These multiply the discriminator outputs by a factor weighted according to the energy ranges. A smaller factor is used for the lower levels because the response factor of sodium iodide is inversely proportional to the gamma quantum energy. The outputs of the weighting circuits are connected to a summing circuit.

Title: Carbon electrode firing waste gas purificn. - by passing cooled gases through electrofilter and active carbon filter
Inventor: GOCHT PAUL G ING GRAD
IPC: B03C3/019
Filed: 1976-05-11
Abstract: Hydrocarbons such as tar vapours are sepd. from the waste gases of carbon electrode kilns by cooling the gases to 40-60 degrees C and passing them thorugh an electrofilter to deposit the tar mist. The gases are finally purified by an active carbon or petrol coke filter to a hydrocarbon content of 150 mg/m3 of carbon. This economic method reduces the high tar content in the waste gases (1-3 g/m3) to an innocuous level. Pref. the waste gases from the kiln where the carbon electrodes are fired are first cooled to 40-60 degrees C and passed through electrofilters in the conventional way; the residue of the hydrocarbons are removed in a carbon filter, preferably filled with a carbon material which can subsequently be used as raw material for carbon electrodes.
