Title: Radial configuration of evaporator heating elements
Inventor: ELMORE CARL L
IPC: B01D1/26
Filed: 1986-03-14
Granted: 1991-03-12
Abstract: RADIAL CONFIGURATION OF EVAPORATOR HEATING ELEMENTS               ABSTRACT OF THE DISCLOSURE          A free flow evaporator of the falling film type has the heating elements disposed in a circular configuration so that each extends radially a distance less than the interior radius of the evaporator cylindrical vessel.  Heating vapor is introduced concentrically into the top of the vessel and passes into the tops of the heating elements, and condensate is withdrawn from the bottoms of the heating elements in the vessel.  Excess vapor passes through a vapor vent in the bottom of the vessel.  The boiling liquid, such as black liquor from paper pulp processing, is introduced through a header above an annular channel with a perforated plate bottom, the perforated plate being disposed on top of the heating elements.  The evaporated liquid vapor passes radially outwardly in the vessel, and then upwardly, and is discharged from the top of the vessel and passes to the top of another vessel (providing another effect), to provide heating vapor to the other vessel.

Title: Method for manufacturing zinc hydrometallurgically
Inventor: DYVIK FROEYSTEIN
IPC: C25C1/16
Filed: 1986-11-21
Granted: 1993-03-23
Abstract: ABSTRACT   The present invention relates to a method for manufacturing zinc hydrometallur-gically from zinc-containing starting materials. The method comprises one or more leaching stages, one or more solution purifying stages and one or more electrowinning stages for recovering metallic zinc from the leaching solution obtained. The method is operating with a closed solution circuit. A predeter-mined part volume of the solution obtained in the electrowinning stage or stagesis withdrawn and concentrated by evaporation so as to precipitate any magne-sium and manganese present in the part volume in the form of metal salt crys-tals. The precipitated crystal mass is separated from the residual liquid phase.The liquid phase in this manner purified with respect to magnesium and manga-nese can be recycled to the leaching process or utilized for some other purpose.When the process is carried out in a sulphate environment, the solution obtainedin the electrowinning stage or stages is concentrated to a sulphuric acid concen-tration of at least 60% by weight.

Inventor: SMITH DAVID W
IPC: H04B10/2507
Filed: 1987-01-27
Granted: 1991-04-30
Abstract: ABSTRACT         A method and apparatus for reducing fluctuations such as phase noise in a characteristic of a coherent beam of radiation is described.   The apparatus comprises an interferometer for sensing the fluctuation at the first position  to  generate  an  interference beam.   The interference beam is incident on a radiation detector such as a photodiode which generates an electrical output signal responsive to the intensity of the incident beam. This signal is amplified by an amplifier and fed to a phase modulator.   Another portion of the original laser beam is also fed to the phase modulator.  The arrangement is such that the phase modulations applied to the beam by the phase modulator under the control of the signal from the detector reduce or cancel the phase noise in the original beam.

Abstract: Abstract.   Analysis of [125I].  interferon  gamma  cross-linked  to its receptor on various human  cells by SDS-PAGE revealed that there are at least three different types of human  interferon  gamma receptors. In WISH, HeLa, FS11 and other tissue cells an Mr 90,000-105,000 receptor was found. In monocytes and  in the myeloid cell line KG-1 an Mr 140,000 receptor was found while   in   Daudi  lymphoblastoid  cells  an  Mr  95,000-115,000 receptor was found.     The various  receptors  were  isolated  from  these cells by extraction followed by  affinity chromotography on an immobilized interferon gamma column. The  resulting  purified  preparations  retained their original affinity for  interferon  gamma  and  were used for immunizing mice and subsequent development of highly specific        antibodies.
