Patent AT-A501680-A (AT)
Title: Urea synthesis from ammonia and carbon di:oxide - with two=stage thermal treatment of synthesis prod. and recycle of two separate streams
Inventor: PAGANI GIORGIO
Filed: 1980-10-09
Abstract: Prodn. of urea by the double isobaric recycle method comprises reacting NH3 and CO2 at high mole ratio and thermal treatment of the synthesis product formed at about synthesis pressure in presence of an entraining gas. Improvement is that (a) thermal treatment is in two consecutive isobaric steps with virtually all residual carbamate decomposed in the first step and displacement of decompsn. products with a part of the excess NH3; and in the second the remaining NH3 is displaced by additional heat and injection of a current of CO2; and (b) gases from the first stage are recycled directly while those from the second subjected to condensation and purging with residual gas before recycling as liq. The urea prd. soln. is virtually free of CO2 and NH3 yet excessively large heat inputs are not necessary. Temp. fluctuations in the process can be avoided by controlling the two recycle streams.

Abstract: Process for treating domestic or industrial refuse comprises hammer-milling, sieving, and roll-bounce (ballistic) classification. - After possible removal of larger pieces of paper etc. and of ferromagnetic matter, the refuse passes through an initial disintegrator followed by (mechanical) sieving. A sieve fraction between 10-18 mm. and 35-70 mm. is fed to a ballistic classifier whilst the coarser sieve fraction passes to a second hammer mill from which the thereby further disintegrated product is mixed with the fraction passing to the classifier, which may have 5-8 mm. openings to let through material for mixing with the finest sieve fraction.

Title: Coupling of molecular units by deselenization of selenocarbonyl compounds
Inventor: ENGLER EDWARD M
IPC: H01B1/12
Filed: 1975-03-21
Granted: 1979-07-17
Abstract: Abstract of the Invention Organic molecules can be coupled via their seleno-carbonyl derivatives.  Generally, the synthesis can be des-cribed by the following reaction equation:                   where     can be a cyclic or heterocyclic organic compound and R can be alkoxy, phenoxy or phenyl, preferably CH3O, C2H5O, C6H5O, C6H5 and the like.  The reaction is usually carried out in a refluxing solvent, the choice of the solvent being determined by the stability and by the ease of coupling of a particular substrate.  Groups that tend to stabilize the selenocarbonyl require higher boiling solvents and longer refluxing times.  Aromatic solvents, such as benzene or toluene are well-suited for the coupling reaction.  In some cases, refluxing the substrate in the alkoxy-phosphorus base as solvent may be advantageous. This new coupling procedure permits the synthesis of the hitherto unknown compounds:  tetraselenofulvalene (TScF), the selenium analogue of tetrathiofulvalene (TTF), and disolenodithiofulvalene (DSeDTF).  Highly conducting char?e transfer salts of tetraselenofulvalere and diselenodithio-fulvalene with totracyano-p-quinodimethane have also been prepared.  The materials of this invention are useful in the organic electronic devices described the United States Patent No. 3,953,874, issued April 27, 1970, to Arieh Aviram et al. and assigned to the same assignee as is the present application.

Abstract: PRODUCTION OF CLEAN SYNTHESIS OR FUEL GAS                (D#74,665-FB) ABSTRACT OF THE DISCLOSURE       An improved continuous partial oxidation process for producing clean synthesis or fuel gas from a hydrocar-bonaceous fuel feed is disclosed wherein the hot effluent gas stream from the reaction zone of the gas generator is cooled and cleaned by discharging the gas stream directly into a relatively large body of hot liquid hydrocarbon im-mersion fluid.  A portion of the immersion fluid is contin-uously removed from the immersion vessel and is cooled in an external cooler to a temperature in the range of about 300 to 850°F. but above the due point of the water in the process gas stream.  For example, the external cooler may be a waste heat boiler for the production of high pressure steam.  Portions of the cooled immersion fluid optionally in admixture with scrubbing fluid obtained subsequently in the process are recycled to the immersion vessel, and op-tionally to the gas generator as at least a portion of the hydrocarbonaceous fuel feed.  The effluent gas stream leav-ing said immersion zone may be subjected to additional cleaning by being scrubbed with said scrubbing fluid com-prising make-up hydrocarbonaceous fuel and particulate carbon in a separate scrubbing zone.  Additional cleaning of the effluent gas stream may be effected by scrubbing with noxious by-product water.

Abstract: Application for Patent of RICHARD R. ERNST    for TWO DIMENSIONAL GYROMAGNETIC RESONANCE SPECTROSCOPY               ABSTRACT OF THE DISCLOSURE The multiplet spectral structure produced by coupled gyro-magnetic resonators, such as heteronuclear coupling, is resolved by inducing a train of transient free induction decay (RID) resonances of a first group of gyromagnetic bodies, such as carbon-13 nuclei coupled to a second group of gyromagnetic bodies, such as protons, and detecting the FID resonance.  A decoupling r.f. magnetic field is applied to the second group during free induction decay resonance of the first group for decoupling the spins of the first and second groups during detection of resonance of the first group.  The duration of the decoupling effect is changed from one successive free induction decay resonance to the next and the detected resonance data is stored as a function of the change in the decoupling effect.  The detected resonance data which is a function of two time intervals is then double Fourier transformed into the frequency domain and displayed as a two dimensional plot for resolving the multiplet structure of the spectra of the first group of gyromagnetic bodies.
