Abstract: The invention relates to a method for preparing a coffee concentrate, wherein the coffee is subjected to two extractions, while the second extraction is carried out at a higher temperature than the first extraction. The method is suitable for preparing liquid as well as solid concentrates. The method produces a new concentrate that forms a further aspect of the present invention.

Abstract: The present invention pertains to a process for carrying out a high-speed stop in a Fischer-Tropsch process which comprises providing a feed to a fixed bed reactor comprising a Fischer-Tropsch catalyst, the reactor being at reaction temperature and pressure, and withdrawing an effluent from the reactor, wherein the high-speed stop is effected by blocking provision of feed to the reactor and simultaneously blocking the withdrawal of effluent from the reactor.

Abstract: A method of performing a direct memory access has the steps of selecting a peripheral device for performing a direct memory access through a direct memory access controller; providing a partial address by the peripheral device to the direct memory access controller; and forming the source or destination address by combining the partial address with selected bits from a source register within the direct memory access controller.

Abstract: A process for producing a purified gas stream from a feed gas stream comprising contaminants, the process comprising the steps of: (a) removing contaminants from the feed gas stream to obtain the purified gas stream and a sour gas stream comprising H2S and RSH; (b) separating the sour gas stream comprising H2S and RSH into a gas stream enriched in H2S and a residual gas stream comprising RSH; (c) converting H2S in the gas stream enriched in H2S to elemental sulphur in a Claus unit, thereby obtaining a first off-gas stream comprising SO2; (d) converting SO2 in the first off-gas stream comprising SO2 to H2S in a Claus off-gas treating reactor to obtain a second off-gas stream comprising H2S; (e) converting RSH from the residual gas stream comprising RSH to H2S in an RSH conversion reactor to obtain a residual gas stream comprising H2S, wherein at least one of the operating conditions of the RSH conversion reactor is different from the corresponding operating condition of the Claus off-gas treating reactor.

Abstract: Metal working fluids being oil-in-water emulsions comprising alkylated polyvinylpyrrolidones as surfactants for emulsifying the oil in water. The alkylated polyvinyl-pyrrolidones having a molecular weight of about 1,000 up to 50,000 provide emulsions showing a high emulsion stability under varying and severe processing conditions of metal working fluids. Further, advantages of the metal working fluids are the narrow distribution of the droplet size, the high stability against varying temperature, the high stability against varying quality/composition of the make-up water, a high capacity of dispersing metal fines in the metal working fluid as well as excellent film forming characteristics.

Abstract: A shielded electrical connector having a housing and a cover each of which are formed by inmoulding an insulative portion respectively within a respective outer shield portion. Terminals are mounted within the housing and the housing and cover are joined together. Shielding characteristics are improved by a carrier strip interconnecting the shielding of adjacent connectors within a connector stack. Further shielding improvements are recognized by incorporating a contact surface external the shielding for engaging an outer reference terminal. The connector includes terminals having a floatable contact portion and a support feature for preventing damage to the terminals as a result of stubbing with a mating terminal. The connector being impedance matched to the cable.
