Abstract: Methods are directed to the use of a supercritical fluid for finishing a target material with a finishing material. One or more variables selected from temperature, pressure, flow rate, and time are manipulated to increase efficiencies in the finishing process. As temperature or pressure are decreased causing a change in the density of a supercritical fluid carbon dioxide, which in turn causes a precipitation of dissolved material finish with the carbon dioxide, other variables are maintained above threshold values to increase the uptake of the material finish by the target material. This improvement reduces time by limiting cleaning processes of the system, saves materials used in the cleaning process, and saves energy used to achieve cycles of the process, in aspects.

Abstract: Supercritical fluid (“SCF”) is used to scour a target material to leave scour elements, such as oligomers and oils from the target material. Carbon dioxide (“CO2”) is introduced into a pressure vessel also containing the target material to be scoured. The CO2 is raised in temperature and pressure to a SCF state. The CO2 is recirculated within the pressure vessel to scour the target material. An exchange of the CO2 is occurs allowing for the scoured elements to be removed from the CO2 and therefore from within the pressure vessel. Operation variables such as temperature, pressure, time, internal flow rate, and CO2 exchange are adjusted to achieve a scouring of the target material.

Abstract: A method and apparatus for providing a temporary identity module to a device (1) in a communication network. An RO Server (2) receives a request for an identity module (51) from the device (1). It then obtains an identity module and generates an encryption key (S4, S5). The encryption key is partitioned into a plurality of slices such that no slice comprises the whole encryption key (S6). Each slice is sent (S8, S9) to respective further devices (10, 11) accessible by the server (2) such that no single further device (10, 11) receives sufficient slices to reconstruct the encryption key. A location key is generated (S10) that identifies each slice and the further device (10, 11) to which each slice has been sent. The identity module is encrypted using the encryption key (S11) and sent to the device (1) along with the location key (S12). The device (1) can subsequently use the location key to obtain the slices and reconstruct the encryption key.

Abstract: Methods, a user equipment, a server host, a client application, computer program products, and a server computer program. These methods and components can be utilized by a location based service. One method regards triggering of events in the user equipment based on a position of the user equipment, comprising the steps of: —looking up, in a server database at least one network cell-identity associated with a predefined geographical area, —sending the network cell-identity to the user equipment, —storing the network cell-identity in a database in the user equipment, —obtaining a current network cell-identity to which the user equipment currently is connected, —comparing in the user equipment the current network cell-identity with network cell-identities stored in the database, and —retrieving content associated with the current network cell-identity if the current network cell identity is among the network cell-identities in the database.

Abstract: Matching systems are provided that are configured to determine if a first entity received from a client device of a first user matches with at least one other entity of a plurality of entities indexed in an index in which each entity is associated with one or more index points. The system includes an application server adapted for communication with a matching engine and the client device. The matching engine is configured to index the first entity by associating the first entity with one or more index points in the index; and search for other entities matching the first entity among the plurality of entities indexed in the index by searching for other entities associated with at least one of the index points with which the first entity is associated.

Abstract: A process for introducing a textile treatment material into a textile treatment system, particularly a supercritical fluid carbon dioxide (SCF—CO2) treatment system. The process includes the steps of providing a preparation vessel in fluid communication with a textile treatment system; loading a textile treatment material into the preparation vessel; dissolving or suspending the textile treatment material in near-critical liquid carbon dioxide or supercritical fluid carbon dioxide in the preparation vessel; and introducing the dissolved or suspended textile treatment material into the textile treatment system. The textile treatment material can be selected from a group including a brightening agent, a whitening agent and a dye. A system suitable for use in carrying out the process is also disclosed.

Abstract: Processes for dyeing a hydrophobic textile fiber with a colorant material using a SCF--CO.sub.2 dyebath are described. One process employs cooling, without venting or removing CO.sub.2 from the system, to a target CO.sub.2 temperature at or below the glass transition temperature of the hydrophobic fiber, followed by the venting of the dyeing system to atmospheric pressure. The other process employs venting, without cooling, to a target CO.sub.2 density where dye is no longer soluble in the SCF--CO.sub.2, followed by cooling to a target temperature and then venting to atmospheric pressure. Optionally, the temperature of the dyeing process is established by heating the process according to a selected temperature profile.
