Abstract: Abstract of the disclosure A branched polymer containing silyl groups, a pro-cess for the preparation thereof, coating agents based on the polymer, and the use thereof.     The invention relates to polymers containing silyl groups, the silyl groups being introduced into the poly-mer through ethylenically unsaturated monomers of the gen-eral formula   (a) where R1 = alkyl, aryl, acyl or aralkyl having 1 to 10 carbon atoms, R2 = an organic radical having a polymerizable double bond, X  = a hydrolyzable group, and n  = 1, 2 or 3.          The polymers can be obtained by copolymerization of a) 0.1 to 40% by weight of the silane monomers (a), b) 5 to 30% by weight, preferably 8 to 25% by weight, of monomers containing at least 2 polymerizable, ethyl-enically unsaturated double bonds, and c) 30 to 90% by weight of ethylenically unsaturated mono-mers without groups containing active hydrogen.       The invention also relates to moisture-hardening coating agents based on the polymers containing silyl groups.  The coating agents are suitable, in particular, for automobile repair paintwork.

Title: Carrier material for immobilizing microorganisms
Inventor: TROESCH WALTER
IPC: C12N11/14
Filed: 1987-11-13
Granted: 1992-05-26
Abstract: Abstract Carrier material to immobilize microorganisms. In known carrier materials in bioreactors the reactor is frequently clogged with microorganisms or organic compounds.  The new carrier material ensures that microorganisms or animal cells can be immobilized in high volume concentration without any clogging of the reactor taking place. This objective is achieved in that spheres are used as the carrier material, these consisting--on the one hand--of an open-pore, inorganic sintered body that has in its interior continuous pores that are open to the outside, within which microorganisms and animal cells can be immobilized and multiply and which--on the other hand--are of a density and a diameter such that in a temporary  vortex-bed flow the shear force of the spheres is sufficient to shear off the microorganisms or animal cells growing out of the interior of the spheres and/or on the surface of said spheres. The present invention makes it possible to combine the advantages of a fixed-bed reactor with those of a vortex-bed reactor, and to avoid the disadvantages inherent in both of these.  The carrier material according to the present invention is not restricted to breaking down communal and industrial waste water; it can be used for the biological extraction of essential-nutrient and pharmacological substances and the products of fermentation.

Title: Method and apparatus for separation using fluidized bed
Inventor: ZALTZMAN ARTHUR
IPC: B03B5/46
Filed: 1988-03-28
Granted: 1992-10-13
Abstract: ABSTRACT OF THE INVENTION     A gas is forced upwardly through a fluidization medium, such as sand, producing a fluidized bed which flows under the influence of gravity through an inclined trough.   The separation of the side walls of the trough decreases in the direction of flow of the fluidized bed increasing the depth thereof.  The apparent density of the fluidized bed is main-tained substantially uniform, regardless of the increase in depth, by correspondingly increasing the pressure of the air forced through the medium in a manner corresponding to the depth thereof.  A gas distribution plate beneath the fluidi-zation medium having a higher resistance to the flow of gas than the layer of fluidization medium thereabove contributes to  the  maintenance  of  a  substantially  uniform  apparent density  in  the  fluidized  bed  despite  variations  in  its depth.  The fluidized bed will separate mixture of articles added  thereto  into  a  float  fraction  of  articles  having densities less than the density of the fluidized bed and a sink fraction of articles of correspondingly greater densi-ties.  Upper and lower layers of the fluidized bed entrain-ing float and sink fractions of the mixture, respectively, are separated at the output end of the trough and cleaned of fluidization medium.   The method and  apparatus disclosed have demonstrated utility in the separation and sorting of agricultural  products  of  all  sizes  and  particularly  of products greater than S millimeters in diameter.

Abstract: PROCESS FOR THE MANUFACTURE OF HIGHER FATTY      MONOGLYCERIDE MONOSULFATE DETERGENTS            ABSTRACT OF THE DISCLOSURE:           A process for the manufacture of water soluble higher fatty monoglyceride monosulfate detergents is described which includes reacting a sulfating agent, such as chlorosulfuric acid, with glycerol dissolved in an organic solvent, such as chloroform, to trisulfate the glycerol, reacting the glycerol trisulfuric acid made with a higher fatty acid or a higher fatty acid methyl ester in such a solvent, extracting the reac-tion mixture with a solvent for the monoglyceride disulfuric acid, such as aqueous lower alkanol, and neutralizing the extracted monoglyceride disulfuric acid with an aqueous neutra-lizing agent to make the water soluble detergent salt.  Among preferable detergent salts made are sodium hydrogenated coco fatty monoglyceride sulfate, sodium. hydrogenated palm kernel fatty monoglyceride sulfate,  sodium hydrogenated palm fatty monoglyceride sulfate, sodium hydrogenated tallow fatty mono-glyceride sulfate, and mixtures of two or more thereof.

Title: Method of treating waste gas by irradiation with electron beam
Inventor: AOKI SHINJI
IPC: B01D53/74
Filed: 1988-12-09
Granted: 1994-11-22
Abstract: A waste gas containing sulfur oxides (SOx) and/or nitrogen oxides (NOx) is purified by leading the waste gas to a radiation irradiation zone, adding ammonia (NH3) to the waste gas before, during or after the irradiation, collecting the resulting by-product (ammonium sulfate and/or ammonium nitrate) by means of a dust collector, and releasing the purified waste gas to the atmosphere.  The amount of NH3 to be added is selected so as to be smaller than an amount calculated from target desulfurization and denitrification efficiencies so that it is possible to reduce the leakage of ammonia despite variations in the composition of the waste gas.  Further, an alkaline substance exclusive of ammonia is added to the waste gas within the dust collector or at the upstream side thereof so that the pH of the collected by-product is adjusted to 6 or more, preferably 7 or more, thereby suppressing the adverse effects of sulfamic acid impurities.

Title: Mechanism for deriving accurate frequency reference for satellite communications burst demodulator
Inventor: WATERS GEORGE W
IPC: H04L27/227
Filed: 1989-08-18
Granted: 1992-11-17
Abstract: ABSTRACT OF THE DISCLOSURE    Accurate tuning of a satellite system's burst demodulator to a signal which is subject to frequency offset in the course of its transmission over the satellite link is achieved without the use of high precision oscillators at remote sites, or the transmission of a dedicated pilot tone.  Instead, a dedicated high precision clock is used for the purpose of establishing both the outlink carrier and the return channel carrier.  The modulation of the data on the outlink carrier is also derived from the precision clock source.  At each remote station, the outlink channel is monitored to recover the high precision clock.  This recovered clock is then used as a reference for generating the return channel carrier.  The burst demodulator equipment at the master station monitors both the outlink equipment continuous carrier and burst mode transmissions from the remote stations.  Each of the continuous and burst mode carriers, having been transmitted through the satellite, will undergo the same frequency offset or modification, so that the frequency difference between the outlink channel carrier and the return link channel carrier will always be constant.  The outlink channel carrier, which is available on a continuous basis, is used to derive a local oscillator frequency reference for establishing the burst demodulator's local oscillator reference.
