Inventor: RAGNAR MARTIN
IPC: D21C/
Filed: 2005-09-20
Abstract: The invention relates to a method for the improved oxygen delignification of cellulose pulp with a medium consistency of 8-16 %. The fraction of dissolved oxygen can be maintained at a high level throughout the process by the use of high pressure, greater than 15.0 bar, and by repeated agitative mixing while maintaining the high pressure, such that as large a fraction as just over 20%  of the total oxygen added is dissolved in the fluid phase, and such that the amount of oxygen in the fluid phase is maintained at a high level throughout the complete high pressure section. By the establishment of retention times between the remixing operations with successively increasing retention times, while retaining a high pressure, an optimal adaptation of the remixing is obtained at the time at which a certain fraction of the oxygen dissolved in the fluid phase has been consumed. This means that the amount of oxygen that is dissolved in the fluid phase and that penetrates the cellulose fibres can be maintained at an optimal high level throughout the process for improved delignification of the cellulose.

Abstract: A method and apparatus for encrypting a Mode-S extended squitter exploiting a provided key. The key includes a control key segment, an address key segment, a first message key segment, and a first parity/identity key segment. Adding modulo two the control segment to the control key segment produces an intermediate control segment. Adding modulo two the address segment to the address key segment produces an intermediate address segment. Adding modulo two the message segment to the first message key segment produces an intermediate message segment. Adding modulo two the parity/identity segment to the first parity/identity key segment produces an first intermediate parity/identity segment. Concatenating the intermediate control segment, the intermediate address segment, the intermediate message segment, and the intermediate parity/identity segment produces an intermediate extended squitter. Shifting the intermediate extended squitter according to a linear function shift register produces a shifted-intermediate parity/identity segment.

Abstract: A leaf seal arrangement (30, 50) is provided in which within a housing (33, 53) there are edge portions (40, 60) to inter associate with non parallel chamfer edges (41, 61) in leaf seal elements (32, 52). In such circumstances, deflection of the leaf seal elements (32, 52) in an outward direction (42, 62) or inward direction (43, 63) relative to a rotating shaft (37, 57) creates variation in a control gap X, XX between the edges (40, 60) and the chamfer edge (41, 6l). Such increase or decrease in the control gap X, XX adjusts the aerodynamic radial force that is presented to the leaf seal elements (32, 52) whereby those elements (32, 52) can be more accurately maintained at a desired leaf position for optimising leakage whilst achieving better wear resistance performance.
