Patent LV-13799-B (LV)
Title: Alternative electric power statin
Inventor: JAKIMOVS PJOTRS
Filed: 2007-03-23
Abstract: The invention is related to the field of energetics, especially to systems of obtaining electrical power; it can be used as industrial electric power-station for obtaining environmentally clean electric energy without consumption of fuel resources. The intention of the invention is to increase efficiency of geothermal electric power-station operation and to obtain environmentally clean electric energy. The essential idea of the invention is to exploit physical features of heat pipe and geothermal energetic processes, where carrier of heat, in particular a water, is heated up to 50 ?C in the heat collector 3 by heat-carrying layer of entrails of the earth, and enters the vaporizer 2 of the pipe 1, where it boils instantaneously and transforms intensively into vapour under pressure P = 0,12 kg/cm2. The vapour fills heat pipe 1 and after reaching the mixing 4 and surface 9 condensers is condensed to water, maintaining in this way high level of vacuum in the heat pipe 1. The water transfers its energy to the hydro-turbine 7 or unit of hydro-turbines while running through the return pipe 10, and returns through discharge tube 11 to the heat collector 3, where it is heated and enters again the vaporizer 2. Electric power generator coupled with the hydro-turbine 7 produces electric power, which is transmitted via a cable to surface of the earth to users.

Abstract: The object of the present invention is a process which permits the increase of the bioavailability in the solid formulations of nifedipine and its derivatives. In consists in dissolving the active substance together with a polyethylene glycol, in a common solvent, then absorbing this solution on a micronized, inert excipient, soluble in the gastrointe­stinal juices, and finally, co-precipitating the active substance and the polyethylene glycol by evaporating the solvent.The very large surface of the excipient on which the solution is absorbed, and the presence of polyethylene glycol, wich facilitate the homogeneous distribution of the solution on this surface, permit the active substance to precipitate and become very fine particles.The same results may be also obtained by blending homogeneously the micronized inert excipient with micronized nifedipine, and causing the mixture to be absorbed on a solution of polyethylene glycol, which by subsequent solvent evaporation, precipitates in fine particles that are homogeneously dispersed and in intimate contact with the active substance.Forms of solid dosage prepared with the mixture thus obtained, have shown a bioavailability higher than similar formulations already on the market.

Abstract: Oppfinnelsen angår sementering av en oljebrønn eller et lignende borehull.Ifølge oppfinnelsen blir den teoretiske akustiske impedans av sementen vurdert som en funksjon av noen teoretiske sementeringsparametere, og impedansen blir korrigert som en funksjon av virkelig målt tetthet av sementslagget under pumping. En korrelasjon blir etablert, med dybden som en funksjon av data registrert under sementeringen og borehullets geometri, og en verdi Z = f (dybde) blir utledet fra dette, som muliggjør forutsigelse av den akustiske dempningskurve: CBL (forutsagt) = f (dybde), tilsvarende parametrene for den virkelige sementering.Ved sammenligning med (den målte) CBL-kurven, kan man utlede de eksakte soner hvor en sekundær eller reparasjons-sementering vil være nødvendig.
Patent NO-173656-B (NO)
Inventor: SORMUNEN PEKKA
IPC: C08F10/00
Filed: 1990-07-24
Abstract: The invention relates to a method for the preparation of a supported procatalyst intended for the polymerization of olefins, in which particles are formed from magnesium halide and alcohol, the particles are reacted with an organometallic compound of any of the metals of the groups I to III, the thus obtained particulate product is activated by means of a titanium(IV) compound, and optionally a prepolymerization is carried out for the activated particles. A problem with this kind of a method is how to form particles from magnesium dihalide and alcohol having an advantageous structure for the polymerization of ethylene and particularly ethylene with a narrow molecular weight distribution. The problem has in the present invention been solved by forming the particles by spray-crystallizing a mixture of magnesium dihalide and alcohol to complex particles of magnesium dihalide and alcohol and by using titanium (IV) alkoxyhalide as the titanium compound. The catalytic properties of the particles thus obtained are improved, especially after the prepolymerization carried out by means of ethylene, which leads in the polymerization to a still more active, very hydrogen and comonomer sensitive procatalyst having a better molecular weight selectivity. The invention also relates to the specific use of the procatalyst prepared by such a method for the polymerization of alpha-olefins. By a procatalyst is meant in this context the catalyst component of the Ziegler-Natta-catalyst which is based on the transition metal and which before the polymerization is combined with the organometallic compound of aluminium or some other metal acting as cocatalyst

IPC: G21C7/27
Filed: 1983-11-30
Abstract: The invention relates to an actuating device for two clusters of control rods movable vertically in one and the same fuel array of the core of a nuclear reactor. The first cluster, used for running the reactor, is connected to a first actuating rod (2), the movements of which are effected by a mechanism (27, 28, 29, 30, 34). This rod (2) carries hooking fingers (41), the operation of which is effected by a device (45) mounted slidingly on the end of the rod (2). The device (45) causes the closing of the fingers by means of a spring (46), or on the contrary their opening by overstroke movement towards the top of the rod (2). The second cluster remaining fully inserted into the assembly during a part of the operating cycle of the reactor is connected to a second actuating rod (3). This second rod (3), fitted coaxially within the rod (2), forms a piston (3b) in this rod (2) driven for its upward movement by the opening of a pressure relief valve (65) of the fluid-tight enclosure (1) in which the actuating rods (2 and 3) move. The rod (3) in the top position can be connected to the rod (2) by the fingers (41) engaging in a groove (53) of the rod (3). The invention is applicable particularly to nuclear reactors with improved efficiency employing neutron spectrum variation clusters.
