Title: Isotope enrichment - by use of a magnetic prism and a beam of isotope ions
IPC: H01J49/30
Filed: 1973-12-07
Abstract: Electromagnetic isotope enrichment, partic. of U235 in a mixt. of uranium isotopes, by (i) passing a beam of monokinetic ionised isotopes from an extended source into a magnetic prism with a constnat magnetic field the direction of which is perpendicular to the direction of motion of the ions in the beam and (ii) collecting a aprt of the deflected beam leaving the magnetic prism in a collector the entry surface of which is less than the effective section of the deflected beam so that a mixt. enriched in at least one isotope is obtd.

Patent FR-2296370-A1 (FR)
IPC: A01G31/04
Filed: 1975-12-22
Abstract: A process for growing plants by means of water culture or hydroponics and apparatus therefor are disclosed. The process is particularly well suited for growing relatively bulky plants and includes floating the plants on a nutrient solution by rafts or the like. The rafts are positioned in close proximity to maximize the plant density per unit area of the solution and accordingly the space productivity of the process. As the plants grow on the rafts, the buoyancy of the rafts is increased and the rafts may be laterally displaced proportionally to plant growth to maintain high plant density per unit area of solution. Buoyancy of the rafts is preferably increased by a transrafting step in which a small raft is placed on a larger raft formed to receive the same. In another aspect of the present invention the nutrient solution is used as a transport medium, with the raft supported plants being urged across the nutrient solution as part of plant and/or raft processing steps.
