An evacuation station for collecting debris from a cleaning robot includes a controller configured to execute instructions to perform one or more operations. The one or more operations includes initiating an evacuation operation such that an air mover draws air containing debris from the cleaning robot, through an intake of the evacuation station, and through a canister of the evacuation station and such that a receptacle received by the evacuation station receives at least a portion of the debris drawn from the cleaning robot. The one or more operations includes ceasing the evacuation operation in response to a pressure value being within a range. The pressure value is determined based at least in part on data indicative of an air pressure, and the range is set based at least in part on a number of evacuation operations initiated before the evacuation operation.

A pipe cleaning assembly has a connection fixture having a body defining a cavity. A first aperture, opposing first auxiliary aperture coaxially aligned with the first aperture, second aperture, and opposing second auxiliary aperture coaxially aligned with the second aperture are in fluid communication with the cavity. A first connection flange extends from and surrounds the first aperture, a second connection flange extends from and surrounds the second aperture, a third connection flange extends from and surrounds the first auxiliary aperture, and a fourth connection flange extends from and surrounds the second auxiliary aperture. A bonnet is inserted through the second auxiliary aperture and is positioned within the cavity of the body and includes a generally cylindrical wall and a plurality of openings formed through the cylindrical wall to direct fluid flowing through the connection fixture.

Apparatus and method are disclosed for plasma synthesis of graphitic products including graphene. A plasma nozzle is coupled to a reaction chamber. A process gas is supplied to the plasma nozzle, the process gas comprising a carbon-containing species. Radio frequency radiation is supplied to the process gas within the plasma nozzle, so as to produce a plasma within the nozzle in use, and thereby cause cracking of the carbon-containing species. The plasma nozzle is arranged such that an afterglow of the plasma extends into the reaction chamber. The cracked carbon-containing species also passes into the reaction chamber, and the cracked carbon-containing species recombines within the afterglow, so as to form the graphitic products including graphene.

A filter bag support system arranged to support a filter bag for separating food powder and air, comprising a support cage arranged to be placed inside the filter bag, and a lock ring arranged to be placed inside a top section of the support cage, wherein the top section of the support cage is expandable in a radial direction by the lock ring which is arranged to expand the top section of the support cage in the radial direction, towards an edge of the opening of a cell plate when the filter bag support system is located in the cell plate and when the lock ring is rotated within the top section.
