Apparatus is disclosed for spreading and distributing particles such as glue-coated wood fibers onto a moving web including rotatable axles disposed transverse to the direction of movement of the moving web with each axle including a number of distributors rotatable with the axles and disposed generally obliquely with respect to the axes of the axles, each of the axles disposed at successively increasing heights from the moving web in its direction of movement whereby each of the distributors extends into the wood fiber particles comprising the moving web and distributes the particles across the moving web.

The device is for the dilution of dewatered cellulose pulp that maintains a consistency of 20-30% or greater. By shredding of the pulp to a finely divided dry-granulate, dilution to a homogeneous consistency in the medium consistency range can take place exclusively through hydrodynamic effects from the addition of dilution fluid. The dilution fluid is added to granulate at a position at which granulate is in free fall in a standpipe and above a level Liqlev of diluted pulp in the standpipe. A number of nozzles are arranged around the periphery of the stand pipe, directed in towards the center of the stand pipe, obliquely downwards in the direction of fall of the granulate. It is possible through this simplified procedure to avoid completely the conventional dilution screws, and this reduces the investment costs and operating costs, while at the same time unnecessary mechanical influence of the pulp fibers can be avoided.

The invention relates to a plasma generator (4, 4′) for electrothermal and electrothermal-chemical weapon systems, which plasma generator comprises a combustion chamber (20) having a combustion chamber channel, and a center electrode (24, 24′) disposed inside the combustion chamber channel (20′), which combustion chamber and center electrode are electrically conductive and each comprise a respective first connector (26, 42′, 33, 45′) for an electrical connection to a respective second connector (14c, 49, 14d, 48), interacting with the respective first connector, on the back piece of the weapon system. The connector (42′) belonging to the combustion chamber and the connector (45′) belonging to the center electrode are axially displaceable relative to each one of the connectors (48, 49) belonging to the back piece (14), with a maintained, radial contact between the first and the second connectors (42′, 45′ and 48, 49). The invention also relates to a method for maintaining the electrical contact of the plasma generator.

The method and arrangement is for the feed of a chips suspension from one vessel to a subsequent digester in a continuous cooking process for the production of chemical cellulose pulp. The vessel has an inlet defined therein for the input of chips and an outlet defined therein for the output of a chips suspension. The chips suspension in the vessel has a first fluid/wood ratio established above a second fluid/wood ratio that is established at the bottom of the vessel. The second fluid/wood ratio is at least as great as, preferably greater than, the first fluid/wood ratio. After the output of the chips suspension from the vessel and before the chips suspension is placed under pressure for onwards transport to a subsequent digester, a fraction of fluid is withdrawn from the chips suspension, whereby a third fluid/wood ratio is established in the chips suspension.
摘要:
The vessel in which the chips are pre-treated with steam (ST) is provided with a ventilation channel at the top of the vessel for the leading away of weak gases to a weak gas system (NCG). A simple safety system has been installed with the aim of guaranteeing that these weak gases do not reach a level of concentration at which these weak gases become explosive. The safety system has a control unit (CPU) that detects a process parameter that is indicative of the fraction of moisture in the weak gases and opens dilution lines that supply air for the dilution of the weak gases in the ventilation channel. It is appropriate that the dilution take place in stages, where the dilution lines are opened in stages with successively increasing temperature of the weak gases.

The invention also relates to a method of manufacturing and use of the ammunition round in other more conventional weapon systems than the said electrothermal and/or electrothermochemical weapon systems.
摘要:
The invention relates to a cartridge case (2) and ammunition round (1) primarily for electrothermal and/or electrothermochemical weapon systems, which round comprises the said cartridge case. According to the invention, the casing (10) of the cartridge case comprises or consists of one or more insulated or insulating shells, layers or surfaces (11, 12, 13) for, at least electrically, insulating the casing of the cartridge case from the barrel (14) of the weapon system and also preferably from at least the bottom (16) and/or firing device (5) of the ammunition round as well, but preferably also from the rest of the ammunition round, when the round is used, and also preferably from at least the bottom and/or firing device of the ammunition round as well, but preferably also from the rest of the ammunition round, when the round is stored and handled. The invention also relates to a method for manufacturing an, at least electrically, insulated or insulating cartridge case and an ammunition round primarily for electrothermal and/or electrothermochemical weapon systems, which round comprises such a cartridge case, and also use of such insulated or insulating cartridge cases and ammunition rounds in different weapon systems, but preferably in electrothermal and electrothermochemical weapon systems.

The method is for bleaching cellulose pulp in a bleach line that has at least two bleaching steps. The filtrate distribution is led up through the bleaching line counter-currently to the flow of cellulose pulp established in the bleaching line. A single joint main conduit is used for the bleaching steps. Wash filtrates obtained from the wash steps, used after or before the bleaching step, are led in conduits to branch locations on the train conduit that are positioned downstream of the branch location for drawing off of wash and/or dilution liquor for the wash step in question. All branch points in the joint main conduit are in fluid communication with one another along the main conduit.

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.
