Patent JP-H0698304-B2 (JP)
IPC: C02F11/08
Filed: 1988-02-19
Abstract: A reaction apparatus (20) having an externalized heat exchange mechanism by which heat may be added to or withdrawn from a reactant mixture. In one aspect, a cased well (24) extends into the earth in which at least one reaction vessel (50) is suspended from a support plate (40) at substantially ground level surface (22). The reaction vessel comprises an outer closed-end tube (55) in which an inner open-end tube (60) is disposed in a concentric manner to define an annulus (70) which is in flow communication with the bore of the inner tube. Substantially parallel to the reaction vessel and also suspended from the ground level support plate, is a conduit (45) which extends into the chamber defined by the well-casing. A mixture of reactants is injected into the annulus of the reaction vessel to form a hydrostatic column which exerts substantial fluid pressure at a reaction zone in the lower part of the reaction vessel. A heat-transfer medium is heated to an elevated temperature and then flowed through the conduit into the chamber (30) where the hot heat-transfer medium envelops the reaction vessel. Heat is transferred from the heat-transfer medium to the reactant mixture through the wall of the outer closed-end tube. In the case of an exothermic reaction, when the temperature of the reactants reaches a selected level, the reaction process gives off heat which is withdrawn by the heat exchange medium. As the reactants form reaction products, the reaction products are flowed from the annulus through the bore (65) of the inner tube back up to ground surface level. In another aspect more than one reaction vessel is suspended in a single chamber in a single subterranean shaft. In still another aspect each reaction vessel comprises an inner open-end tube concentrically arranged inside a larger intermediate closed-end tube which is then surrounded by a larger tube to form a heat exchange annulus. Also suspended in the chamber with the reaction vessel is a conduit through which heat-transfer medium is pumped into the chamber during operation. The chamber is partitioned into an upper portion and a lower portion by packing assemblies or by pressurizing the upper portion with an inert gas. As heat-transfer medium flows into the chamber it is confined to the lower portion of the chamber and forced upwardly through the heat exchange annulus which is in heat-transfer relation to a hydrostatic column of reaction products in the inner reaction vessel annulus.

Abstract: A method of and an apparatus for differentiating between hard and soft failures of semiconductor memory cells for the purpose of error logging only hard failures. A spare bit position is appended to each addressable location within the semiconductor memory. The spare bit position is set, if the corresponding addressable location is observed to contain a single bit error during regeneration. The spare bit position is cleared, if the corresponding addressable location is observed not to contain a single bit error during regeneration. An error log entry is made for normal read access to an addressable location observed to contain a single bit error only if the spare bit is set indicating that a single bit error was present during regeneration of that addressable location.

Abstract: The invention relates to a system for the transport of nucleic acids into the cell, which takes place by receptor-mediated endocytosis. A complex can be formed with the polyanionic nucleic acid with the aid of a transferrin-polycation conjugate. This complex is bound to the transferrin receptor, of which there is high regulation in growing cells, and is absorbed into the cell. Suitable nucleic acids are those which inhibit specific genes or RNA function, such as antisense oligonucleotides or ribozymes, or the genes coding therefor. The invention further relates to a process for introducing nucleic acids into the cell, to transferrin-polycation/nucleic acid complexes and to pharmaceutical compositions containing these.

Abstract: In the manufacture of thermomechanically treated rolled steel material, a fine-grained formation of the microstructure is of great importance to the strength and toughness properties of the rolled product. According to the invention, a considerable improvement in the strength and toughness properties, and an associated substantial increase in the yield point values and notched impact strength of a rolled steel product, are achieved if the deformation of the rolled material starts in a temperature range which is below that of stable austenite, and is continued up to just above the Ac3 temperature.

Abstract: The invention relates to a protective-gas arc welding method using a melting electrode for relatively highly and highly alloyed, corrosion resistant steels, especially nickel materials and special steels, in which the welding process is carried out under protective gas. Welding methods of this type are associated, owing to the normally present oxygen contents or the contents of oxygen-carrying compounds in the protective gases, with undesirable oxidation at the welding point. Said oxidising proportions, on the other hand, do contribute to effective welding. According to the invention, a welding process is now proposed in which a protective gas having a proportion of carbon dioxide or a proportion of oxygen or a proportion of a mixture of said gases of from 0.01 to 0.5% by volume, preferably from 0.02 to 0.1% by volume is used. This results in an advantageous welding outcome while welding proceeds surprisingly well.

Title: Process for preventing deposits in a structure's drainage system
Inventor: WEGMUELLER MARCEL CHRISTIAN
IPC: E21B37/06
Filed: 1994-02-14
Granted: 2005-10-26
Abstract: In drainage systems in buildings and excavations there is waste and ground water with a high dissolved material content. These mainly inorganic substances often cause the build-up of hard deposits in the water conveying parts of the drainage systems, e.g. waste water pipes. These deposits reduce the drainage cross section of the drainage systems thus preventing the water from flowing freely and thus causing back-ups which can result in considerable damage. The current processes of removing these deposits are electro-mechanical cleaning and high-pressure rinsing or abrading with water. These processes are laborious, expensive and cause interruptions in operation. It is the aim of the invention to prevent the formation of such deposits. To this end, a conditioning agent in aqueous form is added via a metering installation at one or more points in the drainage system. The conditioning agent is mixed with the water arriving at the next channel and prevents the dissolved substances from separating out and causing deposits.
