  • Publication number: 20140314660
    Abstract: The invention relates to the production of water cluster ions (“hydronium clusters”) at atmospheric pressure for the chemical ionization of analyte molecules. It is proposed that a corona discharge at the Taylor cone of an aqueous liquid, preferably pure or slightly acidified pure water, is used instead of corona discharges on metal tips, which have been the usual method up to now. The hydronium clusters of the form [H(H2O)n]+ can be produced in a discharge chamber, which is separate from the ionization chamber, and introduced into the ionization chamber through a capillary. In the ionization chamber, the hydronium clusters can be heated and reduced in size by means of electrical acceleration and gas collisions, and thus made more reactive in order that analyte molecules of low proton affinity can also be ionized.

  • Patent number: 8409754
    Abstract: A positive electrode active material for use in a non-aqueous electrolyte secondary cell comprises a powdery metal oxide (LiCoO2, LiNiO2, LiMn2O4 or the like). When the positive electrode active material is classified with a classification precision index ? of 0.7 or greater so as to obtain a coarse powder having a classification ratio in a range of 0.1% to 5%, a ratio (B/A) of the content (B) of an impurity metal element in the coarse powder obtained by the classification to the content (A) of the impurity metal element in the powder before the classification is 1.5 or less. The contents of the impurity metal elements are compared with respect to Ca, Mn, Fe, Cr, Cu, Zn and the like (exclusive of the metal element constituting the powdery metal oxide). The positive electrode active material for a secondary cell serves to improve cell performance capabilities and production yields.

  • Patent number: 8337807
    Abstract: A solid mixture of fullerene and titanium hydride, a method of its formation, and a method of its use to rapidly produce a gaseous mixture of molecular hydrogen and fullerene on demand. The solid mixture may be resistively heated by discharge of a high power electrical current from a capacitor bank through the mixture to produce the mixture of hydrogen and fullerene within a few tens of microseconds. The resulting gaseous mixture of hydrogen and fullerene may be ionized and accelerated for the purpose of mitigating electromagnetic disruptions in a magnetically confined plasma.

  • Patent number: 8303766
    Abstract: A method and device for evaporating a predeterminable volume of fluid includes successive addition of partial volumes of the predeterminable volume to a supply line at different adding rates, at least partially evaporating the partial volumes forming vapor film between them and a supply line wall, conveying the partial volumes through the supply line to an evaporator surface, and applying the partial volumes to an evaporator surface region varying as a function of mass and/or volume adding rate of the partial volume, permitting effective evaporation of fluid, particularly urea/water solution. Utilization of the highest possible proportion of evaporator surfaces is achieved by mass and/or volume addition rate-dependent distribution of impingement surfaces on the evaporator surface. This heating strategy in the supply line region ensures the Leidenfrost effect when individual partial volumes are added.

  • Patent number: 8147797
    Abstract: A system for cooling and recuperative heating of a slurry in a metallurgical process which includes heat exchangers, pumps and autoclaves is described herein. The heat exchangers use a non-scaling common liquid heat transfer medium. Preferably, the heat exchangers are tube-in-tube heat exchangers with 3 to 7 slurry tubes in each heat exchanger. An advantage of this system is that it does not use flash tanks. To minimize abrasive wear on impinged surfaces, the velocity of the slurry is not more than 5 meters per second. The slurry comprises a solids concentration of 25% to 50%. Preferably, the pumps in the system are float-type pumps in which the driven liquid from the discharge pumps is also used as the drive liquid for the feed pumps.

  • Patent number: 8114189
    Abstract: A method of reducing or preventing the amount of iron sludge or precipitate that forms as a result of the recovery of silver from chemical solutions, such as a standard photographic solution. The method generally involves the introduction of a source of a conjugate organic base, such as a weak organic acid like citric acid or a salt of the conjugate organic base like a citrate salt, to the chemical fluid either before or during the silver recovery process. Preferably the source of conjugate organic base is introduced by combining it with a binder to form a time release cake or placing it in a container that has a semipermeable membrane that maintains the concentration of the conjugate organic base in the chemical fluid from about 0.2 to about 78 milimolar over a period of time.
