Title: Method for oxidising h2s to sulphur
Inventor: NOUGAYREDE JEAN
IPC: C01B17/04
Filed: 1996-10-30
Granted: 2000-10-03
Abstract: An oxidation unit (2a) is used which comprises, in series, three catalytic stages (3a, 4a, 5a) each containing a catalyst for promoting the selective oxidation of H¿2?S to sulphur up to a temperature .theta.s ? 150 ·C. The gas to be processed (16) is fed through each of said stages and air (50, 53a, 55a) is injected into each stage. An H¿2?S fraction of said gas is adiabatically oxidised to sulphur in each of the first two stages (3a, 4a) with an amount of air such that a temperature no higher than .theta.s is achieved at the outlet of said stages. All the H¿2?S in the gas fed into the final stage (5a) is oxidised in a controlled excess of air at temperatures no higher than .theta.s. The method is useful for processing H¿2?S-containing gases produced by the hydrogenation/hydrolysis of sulphur plant waste gases.

Abstract: This invention relates to a novel method for the chemical preparation of epirubicin or acid addition salts thereof, in particular the HCl salt, from daunorubicin. This process avoids the disadvantages of the prior art. First daunorubicin is methanolized to obtain daunomycinone and dauriosamine methyl ether in very high yields. Daunomycinone is converted to 14-acetoxy daunomycinone by bromination and acetoxylation, while daunosamine methyl ether is converted into an N-protected 4'-epi daunosamirie. The choice of the protecting group of the amino group of the daunosamine methyl ether is important because it has to be removed after coupling the sugar with the aglycone without causing side reactions of the aglycone. Two protecting groups were selected: the trifluoroacetyl group and the allyloxycarbonyl group. After coupling the 14-acetoxy daunomycinone with the N-protected 4'-epi daunosamine, the obtained compound was converted to epirubicin; for the latter conversion two routes were developed, depending on the amino-protecting group.

Abstract: A telecommunications network (10) includes an Originating Switching System (12 1) and a Terminating Switching System (12 2) linked by a plurality of trunks(20 1-20 4). For an incoming call it receives, the Originating Switching System establishes a Circuit Selection Capability Indicator (CSCI) that determines what enhancement, if any, the Originating Switching System will provide to the call. The Originating Switching System also utilizes the CSCI to select an appropriate trunk that is compatible with type of call enhancement, if any, to route the call to the Terminating Switching System which also enhances the call in accordance with the CSCI. The signal processing system per-call-control (SPCC) concept allows different types of calls which are routed on the same trunk to get different call quality enhancements (such as True VoiceR and Echo Control), depending on the call type. SPCC allows a call quality enhancement to be applied to an individual call on a per call basis, and these enhancements can be different at the OSS and TSS, which could give different types of enhancements to the calling party and called party. SPCC allows new signal processing "sound flavors", to be developed on the SPS, and these new sound flavors offered as a new service feature through CSCI Table updates in the switch, without software development. The SPCCconcept provides an evolutionary path for current overlay networks implemented for specialized signal processing requirements, in particular the dedicated TV off network for True VoiceR enhancement avoidance, and the dedicated EC off network to avoidecho cancellation for example for SDS services. The PCC capability of SPCC trunks allows the control of the TV Enhancement and the Echo Cancellation on a per call basis, thereby allowing the SPCC trunks to be used in a shared manner for calls requiring TV enhancement, calls requiring TV enhancement avoidance, and for data calls requiring no echo cancellation. The benefits are a) a very flexible per-call-control capability within a single integrated network, b) cost effectiveness, c) robustness to load surges, and d) improved network efficiency.

Abstract: In a heavy oil emulsified fuel evaporator system in which a heavy oil emulsified fuel, after preheated at a preheater, is led into an evaporator to be heated and then to a separator for separation of its water content and the water content, after separated, is used as a preheating source medium for said preheater, wherein water content separation to a predetermined level is enabled irrespective of load change in a heavy oil fuel combustion equipment and no light oil content is discharged together with the separated water content. Heavy oil emulsified fuel 11a is preheated at a preheater 13, is heated at an evaporator 14 and is led into a separator 15 to be separated of its water content.  Water content, after separated, is sent via a piping 15a to be used as the preheating source medium for the preheater 13.  Inlet temperature of the evaporator 14 is controlled constant and pressure in the piping 15a for leading the preheating source medium into the preheater 13 is also controlled constant.          Further, temperature difference of outlet temperature relative to the inlet temperature of the evaporator 14 is controlled constant.  Thereby, the water content in the heavy oil fuel coming out of the separator 15 can be maintained to a predetermined value.

Abstract: A method of determining or detecting the presence of a donor organ-derived analyte in a biological fluid indicative of donor organ damage following xenotransplantation and, thereby, enabling identification of xenograft organ damage in a recipient comprises capturing said analyte by an antibody which is: a) specific for the donor organ-derived analyte; or b) capable of cross-reacting with said donor organ-derived analyte and directly or indirectly determining the donor organ-derived analyte. This method enables one to distinguish between host-derived and donor-derived analytes and, thereby, to obtain an indication of xenotransplant status and possibly rejection, so that corrective therapy can be undertaken as appropriate as soon as such a donor organ-derived analyte is identified. The method applies to in vivo and ex vivo xenotransplantation.
