Title: Retention of radioactive krypton and xenon isotopes by carbon - from nuclear reactor effluents, to attenuate radioactivity
Inventor: SCHROETER HANS-JUERGEN DR
IPC: C01B23/00
Filed: 1974-10-09
Abstract: Alternation of the radioactivity of Kr and Xe isotopes contained in gaseous effluents of nuclear reactors to a level permitting the release of Kr and Xe into the atmos. by passing the gaseous effluents through column filled with active carbon having a heaping density of 450-650 g/l. at a linear flow speed of 6-1000 cm/min. for Xe and 6-10,000 cm/min. for Kr, is improved by using an active carbon which has such a methanol-adsorption isotherm that the difference of methanol adsorption at p/ps = 0.025 and p/ps = 0.007 exceeds 15 x 10-3 cm3. of methanol per cm3 of heaped active carbon (p/ps being the methanol satn. value). The radioactive isotopes of Kr and Xe are short-lived, and the passage of Kr and Xe through the active carbon column should be sufficiently delayed to reduce the radioactivity of the gas effluent stream to an admissible level. It has been found that the retention time can be conveniently assessed by measuring the adsorption of methanol on the active carbon as described above.

Title: Controlling the thickness of electrolytic metal deposits - on circular cathodic discs
Inventor: PFEIL EMANUEL PROF DR PHIL
IPC: C25D5/04
Filed: 1974-11-05
Abstract: The thickness of electrolytically deposited metal on circular, cathodically connected plates is controlled by arranging the cathode to face a baffle screening a circular anode, the shape of the baffle being a section of a circle whose form determines the thickness of metal deposited on the cathode. Alternatively the anode may be of the shape of the remainder of the circle from which the screen (baffle) is a section. The cathode and baffle or anode are rotated w.r.t. to one another during deposn. Without a baffle, the thickness of the deposit increases uniformly from the cent centre to the edge of the cathode, and with disc or ring shape baffles step-wise variations are achieved. With the above baffle the variation in thickness from the centre to the edge of the cathode can be controlled as required.
