Abstract: The invention relates to bandwidth signalling in a multicarrier wireless telecommunication system. The information is transferred in the band itself (bold carriers) and contains information of the size (f2-f1) and location (f1, f2) of the band (I). The information is repeated in a number of carriers (bold) through out the band.

Abstract: A new and distinct cultivar of Buxus semperviresn, ‘Polar’, found in a province of Sweden where the climate is cold (representing zone 4 of the Swedish Hardiness Map) that exhibits exceptional winter hardiness. ‘Polar’ is further characterized by a dense, compact, and medium to broad growth habit and evergreen foliage with leaves that are broadly elliptic in shape, shiny in appearance, and dark green in color that exhibits no substantial change in coloration during the winter. ‘Polar’ is well suited for topiary and for use in parks and gardens in cold climates, where other Boxwood cultivars are inappropriate.

Abstract: Method of producing a process steam from a first black liquor derived in connection with the production of paper pulp, wherein the first black liquor is treated to give a second black liquor of a higher concentration than the first black liquor as well as a liquid of low concentration, whereafter said process steam is produced from the low concentration liquid.

Abstract: A new and improved way of continuously cooking fiber material, wherein temperatures and alkaline levels are controlled to be maintained within specific levels in different zones of the digesting process in order to optimize chemical consumption and heat-economy and at the same time achieve very good pulp properties. The digesting process includes a top separator that separates the transport liquid from the fiber material and permits the fiber material to be exposed to the cooking liquid.

Abstract: Process and device for mixing fluid into a pulp suspension of cellulose-containing fiber material, in which the pulp suspension is pumped in through a pump inlet (17), brought into rotation and, at the desired reaction pressure, mixed with the said fluid while passing through a reaction sector comprising a stator shell (1), a rotor (7) which is coaxial therewith, and at least one fluid inlet (23), after which the pulp mixture leaves the reaction sector through a pulp outlet (20), in which the fluid, via the said fluid inlet (23), is supplied in the vicinity of the center of rotation of the rotating pulp suspension, where the local pressure in the pulp suspension is lower, due to the centrifugal force increasing radially outwards, than the reaction pressure prevailing at the periphery of the pulp suspension.

Abstract: Arrangement for a land mine which is provided with at least one magnetic field sensing device which is arranged to initiate detonation of the mine when a change in the magnetic field is sensed. A magnetic body is laid out loosely underneath the mine so that when the mine is raised from the ground this results in the mine being removed from the magnetic body, so that a change in the magnetic field which initiates detonation of the mine is sensed by the magnetic field sensing device.
