Abstract: The invention concerns a method and apparatus for separating fluids containing particulate matter into two or more fractions of different densities. A cyclone separator (1) is utilized for this purpose and differs from previous constructions inasmuch as it is a uni-directional, air-cored device having an inlet (7) only for the fluid (A) in the top and two separate outlets (11, 15) in the bottom, remote from the inlet, one (11) of which outlets extend axially of the separator. In operation particles (as defined in the specification) once separated from the streamline (A') in which they enter the device are constrained against traversing that streamline. Means (5) are provided adjacent the inlet (7) to stabilize the initial flow of fluid. The axially extending outlet (11) may be adjustable.

Abstract: A method for utilizing hot spent liquor, produced in a digester as the result of cooking a mass of cellulosic material with cooking liquor, is displaced from the top of the digester by pumping under pressure a displacing liquid into the base of the digester.

Abstract: A method and apparatus for deinking a fibre stock or slurry. In order to optimize the separation process the invention proposes to independently control the air injection phase, the mixing phase, and the separation phase by splitting them into separate steps.Thus, there is provided a separation cell which is fed with slurry from an inlet. Air is introduced into the slurry before entry into the separation cell and before entering a mixing section which mixes the air and slurry before entering the separation cell. The air is introduced under pressure by way of a porous sintered sleeve, while the mixing is achieved by the provision of three turbulence discs in the preferred embodiment. Alternative turbulent generating means may be employed.The mixing ensures contact of the ink with the air bubbles which separate out in the separation cell and rise to the surface as a foam. The foam is removed by suction, while the deinked fibre slurry is drawn off from the tank by means of a weir or stand pipe.

Abstract: A balance valve for maintaining two fluid pressure systems at a predetermined pressure relative to one another. The valve comprises a piston slidably received within a bore and subjected on opposite ends to the pressure in the two systems. Each of the two systems is provided with a relief line whose communication with the associated system is controlled by movement of the piston such that any imbalance of forces acting on the piston causes the appropriate relief line to be opened to balance out the forces. The ports controlled by the piston and communicating with the relief lines are triangular in shape. In one embodiment a respective spring acts on each end of the piston to determine the relative pressure levels in the two systems. In another embodiment means is provided to resist movement of the piston in response to rapid pressure fluctuations.

Abstract: A linear actuator includes a ram and a piston separated by a column of hydraulic fluid in a housing. Upward movement of the ram in the housing first seals a finite quantity of hydraulic fluid in the housing cavity. Continued upward ram movement then causes the piston, and hydraulic fluid beneath it, to move upwardly into a sealed gas chamber to compress a gas and create a source of potential energy. Release of the force moving the ram upwardly permits the compressed gas above the piston to expel the hydraulic fluid from the chamber against the ram thereby converting the potential energy in the compressed gas into kinetic energy in the ram. The hydraulic fluid bears directly against the ram to provide the working stroke of the impact device without the effect of metal fatigue from direct contact between the piston and ram.

Abstract: A method and apparatus for separating a fluid containing particulate matter into a plurality of fractions.In order to carry out the separation of both heavy and light contaminants from the fluid in an efficient manner, there is provided apparatus comprising a reverse vortex cyclone separator and a Uniflow cyclone (uni-direction cyclone) separator. Heavy contamination is removed from fluid admitted to the reverse vortex cyclone separator at an end remote from the fluid inlet and fluid substantially cleaned of heavy contaminants passes from the reverse vortex cyclone separator to the Uniflow cyclone separator by way of an axial passage and/or circumferential passages disposed at the inlet end of the reverse vortex separator. Respective outlets for the accepts and rejects are provided in the Uniflow separator at a location remote from the inlet.
