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 plasticating apparatus adapted to handle a wide variety of synthetic resinous materials without predrying. The plasticating apparatus includes a two-stage screw rotatably and reciprocably mounted within a barrel. A surge suppressor is provided between the first and second stages and is comprised of an integral protrusion of the screw root and a deep channel section immediately preceding the protrusion. The surge suppressor prevents the surge of molten material into the vent area following the holding portion of an injection molding cycle, thereby allowing faster recovery and preventing bleeding of plasticized material from the vent opening.

The first end of the shaft portion is coupled to the head of the whip portion.

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).

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: A barrel mixer and assembly is disclosed. The barrel mixer comprises a rotary mixer barrel and a support for the rotary mixer barrel. The support includes a tipping arrangement for the barrel, wherein the support limits tipping of the barrel between a mixing position in which the barrel is angled to retain its contents, and a pouring position in which the barrel is angled so that its contents are poured out. 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 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.

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.
