Title: Method for selectively removing hydrogen sulfide from gas mixtures containing carbon dioxide and hydrogen sulfide
Inventor: FIELD JOSEPH HERMAN
IPC: B01D53/34
Filed: 1981-08-06
Granted: 1984-12-13
Abstract: A process for selectively absorbing H2S from gas mixtures which contain CO2 and H2S in a molar ratio of 4:1 or greater and in which the gas flow rate varies substantially. Alkali metal carbonate solutions are used with absorption under pressure and at an elevated temperature and desorption by steam stripping at about atmospheric pressure. The degree of selectivity of H2S removal is maintained constant despite substantial variations in the gas flow rate by maintaining a constant stripping steam/gas ratio selected to provide the desired partial pressure of H2S in the purified gas and by adjusting the solution/gas ratio to a value in the vicinity of that at which the partial pressure of H2S in the purified gas remains at said selected value while the difference between the partial pressures of CO2 and H2S in the purified gas reaches a maximum value, and by then maintaining such solution/gas ratio as the gas flow rate varies. The process is particularly applicable to H2S removal from hot gases produced by the pressure gasification of sulfur-containing coal, oil or the like which are to be used in power generation cycles.

Abstract: In a disk type mass storage facility for data processing systems, a disk format which improves handling of defective segments of medium and reduces access time. The format has three layers. A first, physical layer comprises the bytes, sectors and collections of sectors, as well as error detection and correction codes. A second, logical layer is used to address the physical layer and to collect together sectors to form multiplicity of separately addressable spaces, with space having a distinct functional utility. As a third, functional layer the use of data fields in each space is specified. This layer governs the handling of bad blocks if required, and the use of certain format information. At the physical layer, bits are collected into sectors, sectors are collected into tracks, tracks are collected into groups, and groups are collected into cylinders. These are logically, rather than physically, defined collections. A group is set of tracks wherein individual tracks in a group can be selected in the inter-sector rotation time. At the logical layer, the disk is divided into three main areas, each separately addressable. The first main area is broken down into two sub-areas. The first sub-area (12) is available to the host computing system for its use; the second sub-area (14 and 16) is used for replacement of the bad blocks. The second is for format information. The third main area (18) is for diagnostics. Handling of bad blocks is controlled by a hierarchically layered process. A portion of each disk, distributed across the medium, is reserved as spare sectors to replace defective sectors. After a bad sector is replaced, future attempts to the replacement sector. For the simplest revectoring, the bad block is replaced by a replacement block in a known location. If that cannot be done, multiple copies of the replacement block's header are stored in the bad block's data field and the copies are compared to find the replacement address. If the comparison fails, or the header cannot be read, a back-up table is available to match the available replacement addresses with the original address which was replaced. A special code is used to identify blocks wherein the medium is good but the contents of the block are logically corrupted. <IMAGE>

Title: Device for speaker verification
Inventor: CAVAZZA MICHELE
IPC: G10L17/00
Filed: 1984-12-17
Granted: 1988-05-05
Abstract: The device obtains several characteristic parameters from a standard sentence said by a speaker and compares them with average parameters of the same speaker stored in an internal memory and previously calculated. According to the comparison, it obtains a probability value that the sentence spoken belongs to that speaker and compares the value with a threshold normalized to the average parameter variance by a threshold calculation circuit. If the threshold is overcome, the device considers the speaker verified. A circuit determines the real instants of sentence beginning and end using a noise-adaptive threshold in order to limit between these two instants the time interval over which characteristic parameters are to be calculated. A circuit aligns as to time the characteristic parameters just calculated to the parameters of a reference sentence, obtaining standard lengths of the sounds composing the sentence spoken. A variable probability threshold is controlled by the standard deviations of the histogram of the average of the characteristic parameter vectors.

Granted: 1991-08-29
Abstract: The support comprises a bridge plate, one or two rod-shaped bridge supports and a hinge-like bridge attachment for connecting the bridge plate to the respective bridge support. The bridge attachment exhibits a flexible section which is permanently connected to the bridge plate at its one first end and is permanently connected to the bridge support at its other second end. The hinge formed by the flexible section imparts a certain mobility between the bridge support and the bridge plate, but bearings with elements which can be moved frictionally relative to one another are avoided. The special advantage is that the bridge plate and the entire bridge attachment can be formed integrally of one and the same material, which prevents the bridge plate from stiffening in the area of the bridge attachment. <IMAGE>
