Patent FR-2795753-B1 (FR)
Inventor: DE RIGAUD JEAN MATHIEU
IPC: D21H23/14
Filed: 1999-07-01
Granted: 2001-09-14
Abstract: During the prodn. stages for a paper material, using a fraction of recycled paper pulp, the acidification stage uses an injection of carbon dioxide into the pulp suspension at a point where the fractions are in the process circuit between the outlet of the pulper (15) for the used paper fraction and the mixing point where the pulp is mixed with fresh pulp. The second stage dilutes the pulp in at least two phases, using clean water which has been injected with carbon dioxide. The clean water is recovered from the papermaking machine or from an external supply such as from the pulp preparation stage and/or cleaned water recovered from other stages. The carbon dioxide is injected pref. at two points in the fraction treatment circuit, on leaving the pulper for the fractions and the end point of the treatment process. The second fraction processing stage has at least one phase where lumps are broken down and/or at least one complementary cleaning phase for the pulp delivered by the pulper (15). The first injection of carbon dioxide is to set the pH at an intermediate level for the grinding and/or cleaning phases. The second injection gives the diluted pulp a pH compatible with the pH level in force during the mixing stage (2). The diluted pulp has a pH value of 5.5-8.5 from the fraction treatment, and the intermediate pH value of the pulp during grinding and/or cleaning is 7.5-9.0 and pref. 8.0-8.5. The carbon dioxide is injected into one and/or more of the points of: Into the clean water used to dilute the fractions (18); into the clean water (20) for dilution at the outlet of the fraction pulper (15); into the clean water for final dilution of the fraction mixed with fresh pulp; into the pulp fraction on leaving the pulper (15) and before the following stages; or into the pulp fraction at the end of the processing but before mixing with fresh pulp. The carbon dioxide is fed by an initial dilution water feed on leaving the pulper to give a pH value of 7.5-9.0 and pref. 8.0-8.5 to the level at the grinder, and by a second dilution water feed between the grinder and the final stage to give a pH value for the diluted pulp equal to the level in force at the pulp mixing stage, where the fraction is mixed with the remainder of the cellulose pulp. The carbon dioxide is fed as a gas or a liquid, or partially a gas and partially a liquid.

Title: Method for transmutation of radioactive wastes
Inventor: CSOM GYULA DR
IPC: G21C1/30
Filed: 2001-09-20
Abstract: A radiocactive waste containing medium is circulated within two or more systems (1,2,3) separated from each other flowtechnically; and the circulated radioactive waste is exposed to neutron radiations of different energy spectrum in each system by operating a reactor physically united entirety of irradiated sections of the said systems as a nuclear reactor or an accelerator driven subcritical system. Each system (1,2,3) has a heat exchanger (9,10) and, in given cases, a circulating pump (10,21) and an expansion tank (5,16,27). The disclosed apparatus has two or more reactor regions (1,2,3) separated from each other by partitions (37,38) and, preferably, arranged coaxially within a reactor space encircled by a common shell structure (39).

Title: Method and computer program for colour separation
Inventor: ZUERCHER BRUNO
IPC: H04N1/54
Filed: 2001-04-03
Abstract: The invention relates to a system for dividing a colour image in at least three separation colours, preferably four separation colours. In the inventive system, separation colours can be entered in a free and location-dependent manner and a location-dependent boundary value can be indicated for each separation colour. Corresponding separation values can be deduced therefrom. In addition, variations of the produced image relatively to the colour image can be calculated. This allows colour separations into arbitrary colours to be carried out, which is particularly useful in the field of safety printing procedures.
Patent HU-230587-B1 (HU)
Title: Short period undulator
Inventor: ALMASI GABOR
IPC: H05H15/00
Filed: 2011-08-18
Abstract: The invention relates to a method for generating electromagnetic radiation, to an optical short-period undulator and to a free-electron laser comprising the latter. To accomplish the method, a high-energy electrically charged particle beam is provided, and high-intensity electromagnetic pulses (7) are generated, and by interfering said pulses with one another an electromagnetic standing wave is created, wherein said standing wave has an electric field strength of a pre-determined peak value. The particle beam is directed through the non-steady electromagnetic field of the standing wave in or in the vicinity of a plane spanned by nodes with maximal electric field strength of said electromagnetic standing wave. Meanwhile, by the electromagnetic field of the standing wave, the particle beam is forced to travel along an undulating path and thereby, in the form of radiation emitted by said particle beam, electromagnetic radiation that propagates in the propagation direction of the particle beam is generated. Said short-period undulator (10) comprises a pulse source (2) to emit high- intensity pulses falling into the terahertz frequency range and an interaction region to direct a high-energy electrically charged particle beam, in particular an electron beam, through the undulator with undulator effect. The undulator effect is provided in the interaction region through a dynamic effect developing in or in the vicinity of a plane spanned by nodes with maximal electric field strength of an electromagnetic standing wave created by the interference of high-intensity pulses falling into the terahertz frequency range, emitted by said pulse source.
