The present disclosure provides a valve (123), comprising a channel body (1231) defining a bent channel space, an elastically flexible membrane (1233), which separates a control space (Sc) from a flow space (Sf) in the channel space, a control connection (1232), providing a fluid connection to the control space (Sc), The control space (Sc) is provided at a radially outermost portion (Co) of the channel space, as per a channel bending radius (Ro), such that the membrane (1233) is flexible between an open position, whereby a cross section of the flow space (Sf) is substantially that of the channel, and a closed position, whereby the membrane substantially seals against a radially innermost portion (Ci) of the channel, as per the channel bending radius (Ri). Use of the valve in a separator is disclosed, as well as a separator comprising such valve and a method of cleaning a separator body.

A dust filter is configured to filter air drawn into a vehicle canister. The dust filter includes a filtration member and a case. The case has an inner chamber for accommodating the filtration member. The case has a drainage port for draining liquid that has infiltrated the inner chamber. The drainage port is at least one opening formed at the bottom of the inner chamber. The case includes a cover that covers the drainage port. The cover has an outlet that opens to the outside. The outlet is lower than the drainage port. At least one baffle plate is disposed inside the cover. The baffle plate has a slope on the side of the baffle plate facing the drainage port, thereby forming a ramp.

A system for preventing debris buildup in vacuum sensor lines includes: a manifold, including a positive air pressure source and a controller; and one or more positive air pressure lines. Each positive air pressure line is in fluid communication with the manifold and can be placed in fluid communication with a vacuum sensor line. The controller is operably connected to and selectively activates the positive air pressure source to emit a positive flow of air, which can be directed into the one or more positive air pressure lines, and then into and through the associated vacuum sensor lines to evacuate debris. In some embodiments, a positive flow of air can also be directed through one or more vacuum lines of the end effector to promote the release of a parcel engaged with the end effector and/or clear the vacuum lines of debris.

A containment booth assembly includes a floor, a plurality of vertical sidewalls, and a plurality of sliding panels corresponding to each of the vertical sidewalls. The plurality of sliding panels define an extendible top portion, the extendible top portion extendible upwardly and configured to interface with a ceiling surface of a room above the containment booth assembly. In a non-limiting aspect or embodiment, one or more of the plurality of vertical sidewalls is rotatably mounted to vertical support beams and define an extendible side portion. The extendible side portion is extendible horizontally and configured to interface with a wall surface of the room beside the containment booth assembly.

Provided is a laser ablation system and method for decontamination of radioactive particles. The system includes a laser head assembly, comprising a laser for ablating radioactive particles from an underlying material, a shroud surrounding the laser for containing the ablated radioactive particles; and a suction nozzle for receiving an airflow from the shroud and releasing the airflow, wherein the airflow contains the ablated radioactive particles, and the waste management system for removing and containing the ablated radioactive particles, comprising a gas pulse regenerable filtration system for removing radioactive particles from the airflow and depositing them in a containment flask, and a vacuum for moving the airflow through the hose into the containment flask.

A dust filtering and collection system for filtering dust and other debris particles from an incoming dust laden air stream, such air stream generally being used for conveying granular material into or from a bulk tank trailer, a railroad car, or other conveying vehicle, the filtering system designed to be functioned by vacuum air pressure, operatively generated by a blower, to draw in the soiled air into the system, to cleanse such air for further use in the conveying of the granular material. The air flow may be reversed, to provide for a dislodging of any dust particles from the filtering system, and to cleanse the filter for further efficient usage of the system in conveying granular material into or out of the tank trailer, or other vehicle during usage.

A fresh air intake system for overburden drills with an air intake assembly mounted along the drill mast to access air at the greatest practical height above ground, an air filter assembly, and a pressure blower/circulating fan assembly to supply the cleanest air practicable into the operator's cab under positive pressure. The height of the drill mast is utilized to access cleaner air at greater heights, with the air inlet located strategically toward the top of the mast. The intake assembly includes a rain cap, an intake tube mounted along the drill mast, and a flexible section at the drill mast pivot point to accommodate raising and lowering of the mast without interference or obstruction. The air filter assembly is mounted in series with the pressure blower/circulating fan assembly, which operates with negative inlet pressure and supplies filtered air under positive pressure into the enclosed cab.

The present invention relates to a vacuum cleaner filter bag made of a thermally weldable filter material which forms the sealed internal space of the vacuum cleaner filter bag. The internal space is thereby closed at least on one side by means of a weld seam configured according to the invention, in the case of which at least two layers of the filter material are welded together. The weld seam configured according to the present invention is distinguished by a far higher tearing strength, compared with weld seams as are known from the state of the art. The invention relates in addition to a method for the production of the vacuum cleaner filter bag, to a tool for the production of the high-strength weld seam and also to an ultrasonic welding unit in which this tool is integrated.

An air purification plant, having a partition wall for the spatial separation of a dirty-air space, which is disposed upstream, from a clean-air space, which is disposed downstream, which partition wall has a support frame and a plurality of filter boxes which project from the support frame in the direction of the dirty-air space, and the filter boxes have at least one filter wall which extends from the support frame into the dirty-air space. The filter boxes are in each case open only in the clean-air space which is disposed downstream, wherein filter walls, which face one another, of adjacent filter boxes in each case form a filter pocket which is open on the upstream side and at the bottom, and for switching from one filter pocket into an adjacent filter pocket a suction nozzle is moved through below the filter box which separates the two filter pockets.

The present disclosure provides a valve (123), comprising a channel body (1231) defining a bent channel space, an elastically flexible membrane (1233), which separates a control space (Sc) from a flow space (Sf) in the channel space, a control connection (1232), providing a fluid connection to the control space (Sc), The control space (Sc) is provided at a radially outermost portion (Co) of the channel space, as per a channel bending radius (Ro), such that the membrane (1233) is flexible between an open position, whereby a cross section of the flow space (Sf) is substantially that of the channel, and a closed position, whereby the membrane substantially seals against a radially innermost portion (Ci) of the channel, as per the channel bending radius (Ri). Use of the valve in a separator is disclosed, as well as a separator comprising such valve and a method of cleaning a separator body.
