Abstract: A structured packing element has the shape of a rectangular flat plate, and is provided with slots and recesses. The slots are intended for assembly by interlocking the structured packing elements together in order to form the structured packing. The recesses are provided in order to form channels within the structured packing. A packing structure can be obtained by assembling such packing elements. Such a packing can be used for an operation of bringing a gas and a catalyst into contact. A manufacturing process of such a structured packing is also disclosed.

Abstract: A method for treatment of a gas having 10 to 0.5% by volume of at least one of COS and CS2, and 30 ppm to 5% by volume of unsaturated hydrocarbons: a) hydrogenation of organic compounds unsaturated with respect to paraffins by contacting the gas with a hydrogenation catalyst in the presence of hydrogen at 100 to 400° C., to provide an effluent that is low in unsaturated hydrocarbon compounds, the hydrogenation catalyst having at least one metal that is palladium, platinum, nickel, or cobalt deposited on a porous substrate. b) catalytic hydrolysis-hydrogenation in the presence of water of COS and/or CS2 present in the effluent of a) to provide an H2S-rich effluent by bringing the effluent from a) into contact with a hydrolysis-hydrogenation catalyst.

Abstract: An installation and a process which jointly implement compression of acid gases from a hydroconversion or hydrotreatment unit and gaseous effluents from a catalytic cracking unit.

Abstract: The present invention describes a process for heating the reboiler of the propane/propylene separation column situated downstream of an FCC unit and fed with the C3 cut from said FCC unit, a process consisting of heating the water in a hot water circuit by means of one or more process fluids originating from units placed upstream and/or downstream of the FCC unit and called hot fluids, one of these fluids being constituted by the overhead vapours from the fractionation column connected to the mild hydrocracking unit.

Abstract: An installation for detecting and displaying the failures of the functional systems of an aircraft is described. The installation can include both a general alarm system (4) connected to said functional systems (2) and to the auxiliary alarm detection means (5) originated from said functional systems, and a complementary alarm system (6), connected to said functional systems (2), independently from the general system (4), and able to indicate a breakdown not detected by the general system on the instrument panel of the cockpit.

Abstract: The present invention relates to a process for treating a gas containing from 10 ppm by volume to 0.5 volume % of at least one of the compounds COS and CS2 and from 30 ppm by volume to 5 volume % of unsaturated hydrocarbon compounds, the said process comprising the following stages: (a) a hydrogenation of the unsaturated organic compounds to paraffins is carried out by contacting the said gas with a hydrogenation catalyst in the presence of hydrogen, (b) a catalytic hydrolysis of COS and/or CS2 present in the gaseous effluent from stage a) is carried out in the presence of water and a hydrolysis catalyst.

Abstract: A method and a system for automatically managing check lists on an aircraft. The system (1) comprises means (8, 12) for determining and presenting the moment when the next check list should be implemented.

Abstract: A portable storage device (MC) is disclosed, which comprises a memory (MEM) for storing data (DAT), a data interface (INT) for exchanging data (DAT) between the memory (MEM) and a host device (DEV), radio communication interface (RI) designed for receiving a key (K) from a transponder (T), checking means (COMP) for checking if a key (K) has a predefined value (V, and access inhibit means (SW) for controlling access to the memory (MEM), wherein the access inhibit means (SW) are controlled by the checking means (COMP). Access to the memory (MEM) is only granted if a certain key (K) can be received, which means that a certain transponder (T) has to be in the vicinity of the portable storage device (MC) for granting access. Furthermore, data (DAT) which is transferred from host device (DEV) to memory (MEM) can be encrypted and data (DAT) which is transferred from memory (MEM) to host device (DEV) can be decrypted. In this way for example commonly used memory cards can be secured against unauthorized use.

Abstract: A method for breathing of scheduling algorithms for a storage device (110). The method including: (a) computing a worst-case duration of a breathing cycle (P) for the storage device (110); (b) starting a breathing cycle; (c) determining if one of the following becomes true before the end of P: (i) a number of real-time requests is at least a predetermined threshold based on a number of data streams and performance parameters of the storage device; and (ii) a number of pending requests for any single stream becomes more than one; (d) if at least one of (i) and (ii) remain true during the duration of P, starting a subsequent breathing cycle after completion of the breathing cycle; and (e) if both of (i) and (ii) are not true during the duration of P, waiting P time units from the start of the breathing cycle before starting the subsequent breathing cycle.

Abstract: This invention concerns new biocidal compounds of formula (I) wherein R is H or CH3. Of particular interest are two isomers that are named malayamycin A and desmethylmalayamycin A. These isomers, which may be prepared by growing under controlled conditions a previously unknown strain of micro-organism from the species Streptomyces malaysiensis, are characterised by nmr and mass spectroscopic data. They have biocidal activity, including anti-fungal, anti-viral and anti-cancer activity, and are of special interest for use in agriculture, horticulture, animal and human health.
