Patent ES-428157-A1 (ES)
Title: Radiation-sensitive switching circuits
IPC: G01T1/17
Filed: 1974-07-11
Abstract: A radiation-sensitive switching circuit includes a light emitting diode which from time to time illuminates a photo-transistor, the photo-transistor serving when its output reaches a predetermined value to operate a trigger circuit. In order to allow for aging of the components, the current flow through the diode is increased when the output from the transistor falls below a known level. Conveniently, this is achieved by having a transistor in parallel with the diode, and turning the transistor off when the output from the photo-transistor becomes too low.

Title: Coupled cationic and anionic method of separating uranium
IPC: C22B3/26
Filed: 1974-10-31
Abstract: Uranium is separated from contaminating metal ions in an aqueous feed liquor containing the uranyl ion. The liquor is extracted with a first, non-interfering, waterimmiscible, organic solvent containing a reagent which reacts with the uranyl ion to form a complex soluble in the organic solvent. The organic solvent is scrubbed with water if necessary, then stripped with a stripping liquor of an aqueous sulfuric acid liquor having a pH of about 0.5 to about 6 containing a reducing ion or an aqueous carbonate solution having a pH of about 8 to about 9. If the sulfuric acid liquor is used the stripped uranous ion is oxidized and the sulfuric acid liquor is diluted to prevent the precipitation of a uranium complex. The stripping liquor is extracted with an amine liquor comprising a second, noninterfering, water-immiscible, organic solvent and a tertiary or quaternary amine. The amine liquor is stripped with an ammonium carbonate solution to precipitate a uranium complex. The uranium complex is filtered off and may be calcined to produce U3O8 or UO2.

Title: Volatile material liberating composition
IPC: A61L9/04
Filed: 1975-03-17
Abstract: A solid air-freshening product contains an active substance which is present in a gel formed from the metal soap with a gelling action and paraffin and which gradually evaporates from the gel. The metal soap acts in this case as the actual carrier material which does not evaporate.

Title: Enclosed flotation device
IPC: B03D1/26
Filed: 1978-04-28
Abstract: A process for clarifying by flocculation a turbid liquid which forms a foam with injected gas and which contains material that, with gas, will form a floatable floc.
