摘要： A fluid injection apparatus and method of injecting fluid are disclosed. The apparatus includes a control syringe electrically connected to a power-actuated syringe. A sensor is provided proximate the control syringe to monitor the position of the plunger therein, with a signal representative of plunger position then being communicated to a processor for calculation of a corresponding control signal. The control signal is received by an actuator of the power-actuated syringe to move the plunger of the power-actuated syringe in a manner related to movement of the control syringe. The control syringe is provided with a feedback device to provide the operator with an indication as to the pressure of the fluid being injected into a patient.

摘要： In a hydrocyclone, particularly for deinking of paper pulp, a movable generally cylindrical plug is utilized to define an annular space near the accepts withdrawal conduit to effect release of obstructions should the annular space become clogged. The plug is biased by a spring, and moved against the spring pressure to enlarge the annular space automatically in response to a build up of back pressure. The plug also may be moved manually from exteriorly of the hydrocyclone housing, or may be operated by fluidic elements on a periodic basis to clean the annular space whether or not there has been a build up of back pressure. The hydrocyclone preferably is a gas sparged hydrocyclone, and recycled paper--with print on it--having a consistency of at least about 2% is treated to effect deinking.

摘要： Medium consistency (e.g. about 5-18%) paper pulp is mixed with a treatment fluid by fluidizing them while subjecting them to a constantly changing shear field in radial and axial planes. This is accomplished by providing a mixer rotor having a constantly varying cross-section along a dimension of elongation. The rotor may comprise a body having an external surface simulating alternately oriented cone frustums along its axis of rotation, with vanes connected to the external surface and including portions following the surface contour. A disk may or may not be provided at the end of the body connected to a shaft. A first interior housing portion has a configuration mimicking that of the rotor, while a second housing portion defines a fluidization zone with the disk.

摘要： A mixer, having a unique rotor, is particularly suitable for mixing paper pulp having a consistency of about 6-15% (medium consistency) with a bleaching gas having an ozone content of at least one percent, and typically at least six percent. The rotor comprises a disc shaped base, a hub at the center of the base for connecting it to a drive mechanism for driving the rotor at an angular velocity of 1000-6000 rpm, and one or more rings concentric with the base and extending outwardly from the base at least about three inches (and of the same for different heights). A number of blades may extend radially through the center of the base along the contour of the rings, extending outwardly from the base, rings, and hub. Degassing holes may be formed in the hub and connected up to a suitable degassing structure in the mixer. The rings may have a cross-sectional shape corresponding to that of a truncated right circular cone frustum, or may have a rectangular cross-section. The rotor is mounted in a housing having a pulp inlet and outlet, and the stator has complimentary shaped cooperating surfaces with the rotor defining annular mixing volumes, the cooperating surfaces having a spacing of 0.5 inches or less (preferably 0.25 inches or less). The fluid to be mixed with the pulp is introduced into the inlet adjacent the rotor and into the mixing volumes, for example at the extremity of the rings from the base.
