Abstract: ABSTRACT OF THE DISCLOSURE     In a cyclone classifier wherein the material to be processed is swirled in a casing having a conical lower portion and classified, a cylindrical body is provided in the casing, so as to surround the lower end of a gas/liquid outlet pipe and extends downwardly below an inlet port for the material to be processed, so that the sectional area of passage for the material to be processed swirled in the casing will be made smaller, thus increasing the classifying point while keeping the pressure loss at a minimum.  From another aspect, annular pipes formed with gas/liquid inlet ports are provided around the outer periphery of a lower part of the casing so as to communicate with the casing so that gases or liquids will be blown into the lower part of the casing through these pipes to form a swirling current, thus allowing the material to be processed to be reclassi-fied and increasing the classifying point.

Title: Process for the hydroformylation of sulfur-containing thermally cracked petroleum residua and novel products thereof
Inventor: OSWALD ALEXIS A
IPC: C07C29/16
Filed: 1987-10-22
Granted: 1992-01-28
Abstract: ABSTRACT OF THE DISCLOSURE   A catalytic process for the hydroformylation of olefinic,  sulfur containing thermally cracked petroleum streams to produce aldehydes  and/or alcohol  is disclosed.  The  catalysts  are homogeneous  transition  metal carbonyl complexes.   Especially preferred  catalysts  for low  and  medium pressure hydroformylation are cobalt and rhodium carbonyl hydride complexes in which  some of the carbonyl  ligands have  been replaced  by  trivalent phosphorus ligands.   In a  preferred high  pressure hydroformylation.  the sulfur-containing naphtha and  gas  oil distillate  feeds are produced  from vacuum residua by  high temperature thermal  cracking.  Such feeds  contain more than 20% olefins  with 1-n-olefins as the  single major types.   These olefin components are hydroformylation in the presence of a cobalt  carbonyl complex to  product a  novel  type of  semilinear aldehyde  and/or  alcohol product containing an average of less  than one alkyl branch per  molecule. The alcohols are converted to dialkyl phthalates and other esters having  a unique balance  of  plasticizer  properties.   They  are  also  useful  for producing novel surfactants, particularly ethoxylated derivatives. For the preparation of produces containing minimal concentrations of sulfur compounds,  narrow  distillate fractions  of  thermally  cracked residua are  preferred.  In  the  C6 to  C11  carbon range,  single  carbon fractions of  sharply reduced  aromatic hydrocarbon  and thiophenic  sulfur content can  be obtained.   These fractions  of  increased  linear  olefin content can  be  advantageously  used  as  hydroformylation  feeds  in  the derivation of  low  sulfur  containing alcohols  and  related  products  of increased linearity.

Abstract: A method for treating boiler water condensate to remove undesirable cations which comprises providing a bed of cation-exchange resin, passing water to be treated through said resin bed, and regenerating said resin with an aqueous solution of a salt comprising a volatile amine and an anion selected from anions which do not form precipitates with any cation present in the water to be treated under operational conditions, and wherein the volatile amine is optionally not the same as that employed as the corrosion inhibitor in the boiler water system. The preferred salts include cyclohexylamine citrate, methoxypropylamine citrate, diethanolamine citrate and monoethanolamine citrate.  The proposed method is particularly advantageous since the anion of the regenerant salt is selected to avoid the formation of insoluble calcium salts.

Abstract: Abstract of the Disclosure There is disclosed a method of producing a transition metal pattern on a glass or  glass-ceramic  substrate by selective exudation of  a transition metal  from a glass substrate containing the metal as an oxide.  The selective exudation is effected by applying an intense, well-focused source of energy to a glass in a pattern corresponding to the  desired  metal  pattern.   This  develops  localized heating, and thereby causes corresponding localized metal exudation  from  the  glass.   The  metal  pattern  may  be rendered electroconductive, and may constitute a pattern of interconnecting lines for microcircuitry.     There is also disclosed a family of low dielectric, copper-exuding,  boroaluminosilicate  glasses  particularly adapted to use in forming substrates for electronic devices such as integrated circuits. The glasses are capable of exuding  copper  oxide,  have  a  coefficient  of  thermal expansion of 30 - 35 x 10-7 at 300°C, a dielectric constant not over 5.0 at 100 KHz, a loss tangent not over 0.003 at 100 KHz and consist essentially, in percent by weight, of 56 - 64% SiO2, 18 - 25% B2O3, 3-11% Al203, 0-2% CaO, 0 - 2% Li2O, 0 - 1% K2O, and Li2O + K2O + CaO being 1.5 - 3% and 1 - 20% CuO.

Abstract: Abstract of the Disclosure:            In order to uniformly distribute a coolant, e.g. air, over gaps between electrochemical cells in high-temperature storage batteries, it has already been proposed to place an open chamber above the groups of cells from which the coolant is preferably conveyed to the cells through holes in a distributor panel.  The object of the invention is to even further improve the distribution of the coolant.  In order to achieve a uniform, quasi-flat incident flow profile for the coolant over the distributor panel, an antechamber is provided for receiving the coolant from at least one inlet opening and for passing the coolant through several throttle locations into an open chamber and then through holes in the distributor panel to the cells.  The invention can be applied to sodium/sulphur batteries, for example.
