摘要： 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.

摘要： The invention relates to a valve system for a space (1) which is under vacuum in relation to its surroundings (3), which valve system comprises a valve unit (7) which is intended to be arranged in association with a wall (2) which delimits the said space and has a wall opening (4) through the said wall, which valve unit comprises a valve (8) which is normally shut and closes the said wall opening but is arranged to be opened and allow air from the surroundings into the said space if the vacuum, i.e. the difference between the surrounding pressure and the pressure in the space, should exceed a previously defined value, which valve comprises a valve housing (12) which can be connected to the said wall (2) in association with the wall opening and which has at least one inlet opening (17) for air, a passage (6) for the air between the said, at least one, inlet opening and the said space (1), a valve seat (15) and a valve body (13) with a sealing surface (21) which is normally pressed against the valve seat by an external force with counteraction by the vacuum in order to keep the passage closed when the vacuum does not exceed the defined value but to permit the passage to be opened by the force developed by the vacuum on the valve body overcoming the external force when the vacuum exceeds the said value. According to the invention, the external force is obtained from a pneumatic power source (34).

摘要： A device for feeding pieces of lumber, one by one, from one location to another location and comprising a plurality of carrier members secured in substantially parallel relation along the length of a frame which bridges between an input location and a delivery location. Each of the carrier members are formed to define a downwardy inclined slope having a stop at the lower end thereof. The upper end of the slope is adapted to receive lumber from the input. An elongate shaft is journaled through the carrier members. A clinch member is rotatably journaled on said shaft and located adjacent each of the carrier members. A stopping arm is provided disposed between each carrier member and adjacent clinch. A pivot pin is attached to each carrier member and a guide pin is carried by each clinch, the stopping arm is rotatably journaled on the pivot pin, one end of the stopping arm being movably engaged with the guide pin and the other end carrying a stop formation. The stopping arm is movable relative to the clinch between one position where the stop formation is above the adjacent slope and a second position where the stop formation is below the adjacent slope depending upon the position of the clinch, the clinch having a V-shaped recess and a substantially circular stop edge, the clinch being movable to place to stop edge sequentially below the slope and above the slope.
