Abstract: The invention relates to a dosing apparatus for pastelike substances and mixtures thereof with a solvent by means of an injector, comprising an integrated shutoff device. The apparatus contains a detection device which detects the amount of paste according to conductimetry. The shutoff device is a dual piston valve closing an opening between the paste supply tube and an injector suction chamber as well as an opening between the solvent supply tube and an injector pre-chamber. The invention also relates to a method for dosing pastelike substances and the mixtures thereof with a solvent by means of such a device. By opening a shut-off device in a supply tube for a pressurized solvent, a dual piston valve moves against an opposing force. This releases a connection between a paste supply tube and an injection suction chamber, followed by a connection between the solvent supply tube and the injector pre-chamber.

Abstract: An apparatus for the separation of immiscible liquids from liquid influent has a containment vessel. An influent channel extends toward the bottom of the vessel so the influent is discharged vertically upward, a downwardly curved deflection plate is mounted above and aligned with the discharge end of the influent channel, and a plate with a downward slope from a central location extends toward the periphery of the vessel in a lower portion of the vessel than the deflection plate. This permits the influent to move radially outwardly thus slowing the influent and providing a residence time for gravitational separation of lighter immiscible liquids from the influent. A gap between the downward slope plate and the discharge end of the influent channel permits gravitational release of trapped immiscible liquids. A transfer tube, a sensor, and a pump are provided to pump the separated immiscible liquids out to a remote location.

Abstract: A simple but still effective sealing device to separate two openings (4, 5), which are arranged at a distance from each other in the outer casing (3) of a shaft suspension unit (1), which supports a shaft (2) of a centrifugal separator in a bearing (8, 9), the shaft extending axially through at least one opening (4) into a space surrounding the shaft (2) in the outer casing (3). The sealing device is provided with sealing elements (12, 13), one connected to the outer casing (3) and one connected to the shaft (2), which surround the shaft (2) and divide the space in two departments (15, 16) connected to one opening each (4, 5, respectively). The sealing elements form between themselves a narrow gap (14) surrounding the shaft (2), which prevents the flow of gas between the departments (15, 16).

The centrifuge has a plurality of blades with radially overlapping edges to keep the fluid being centrifuged compartmentalized and thus quiet for maximum efficiency. Additionally, the scraping blade assembly has blades which are angled in the scraping direction to force the solids towards the exit of the centrifuge, whether that be at the bottom or the top. A programmable logic controller monitors the load on the drive motor and compares a baseline value of load after accelerating the rotor to speed to the value of load while the contaminated fluid is injected into the rotor.

The mixer also a motor having a motor output shaft aligned parallel to an axis of rotation of the barrel, and a mounting plate attached to the motor and surrounding the motor output shaft. Finally, the mixer has a transmission mounted on the support for rotating the barrel. The transmission includes step-down gearing between the motor and the barrel.

Abstract: A compact, high capacity in-tank fuel filter defines a large surface area while simultaneously occupying a relatively small space and defining a small footprint. The filter comprises a body of filtration media and an outlet fitting which is integrally molded to the filtration media and provides communication from the interior of the filter to an associated fuel pump to which it is typically mounted. The filtration media of the body is folded upon itself in a multiple accordion fold configuration and sealed along the non-folded edges. The resulting surface area to size (footprint) ratio provides improved flow capacity, reduced pressure drop and extended service life.

Abstract: The invention refers to a decanter centrifuge particularly for sludge centrifugation, incorporating a drum, a rotor arranged therein and equipped with a helical screw for feed of sludge, a sludge outlet and a reject outlet and a flush washing device for washing (flushing) in countercurrent to the dewatered sludge. In the rotor in close connection to the blades of the helical screw are provided a number of threaded holes for connection of the nozzles of the flush washing device. In response to the washing requirement, certain or entire groups of threaded holes are closable by means of sealing plugs, so that the washing (flushing) can be effected in several consecutive steps with portions without flushing in between.

Abstract: A cartridge based water purification and filtration system which permits cartridge changes without drainage at the input and output ports. Interlocking flanges at the manifold and cartridge lock the cartridge to the manifold and raised surfaces at the cartridge operate the inlet valve with a rotational seating of the cartridge. A spring biased inlet valve depends from a supply manifold input port and cooperates with the filter cartridge to prevent forward flow until the cartridge is seated to the manifold. The check valve includes a split stem which prevents chatter with valve operation. A check valve at the output port cooperates with a sealed bayonet fitting that mates to a concentric outlet port at the cartridge to prevent back flow with cartridge removal.

When running, raw water is supplied from at least the periphery side of the spiral wound type membrane element and permeate is taken out from an opening end of the water collection pipe. In back wash reverse filtration, permeate is introduced from the opening end of the water collection pipe and permeate guided out from the peripheral surface of the water collection pipe is discharged from at least the periphery side of the spiral wound type membrane element.

The first and second thermoplastic members and the thermoplastic fusion element are heated to a molten state using an infrared heater, and the molten fusion element is fused to each of the first and second thermoplastic elements. Prior to being connected by the fusion element, the first and second thermoplastic members are either brought into contact with one another or is held in such a way that they can be connected to each other using the third thermoplastic fusion element.

Abstract: A screening system includes a pressure screen which receives a liquid/solid suspension and filters the suspension to provide an accept portion and a reject portion. The pressure screen includes a housing which encloses a chamber containing a screen basket through which a portion of the liquid/solid suspension passes from a first side of the basket to a second side to form the accepts. A pressure sensor monitors the pressure differential between the first side and the second side and provides a sensed differential pressure signal indicative thereof. The system also senses the accept flow rate and provides a signal indicative thereof to a controller. The controller sets a differential pressure threshold value as a function of the accept flow rate signal and monitors the sensed differential pressure signal. If the sensed differential pressure signal exceeds the threshold value, the controller automatically initiates corrective action in order to reduce the differential pressure across the screen.
