Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that include a cleaning assembly for a container. The cleaning assembly may include a base; a plurality of protrusions extending from different locations about a circumference of the base; and a porous material arranged about the circumference of the base and between the plurality of protrusions.

A method of retrofitting an environmental control system of an aircraft includes inserting the orifice plate through the connector slot and the connector ring slot into the receptacle. The method also includes aligning the covering portion with the connector slot.

A substrate cleaning apparatus configured to clean a surface of a substrate having a circular shape by bringing a cleaning member into contact with the surface of the substrate and rotating the substrate and the cleaning member relatively is provided. A contact region of the cleaning member which comes into contact with the surface of the substrate is widened in a radial shape from a center side of the substrate toward a peripheral side thereof.

A lens cleaning device includes an elongated member having a top surface, a bottom surface, a first end, a second end and a pair of opposing sides. The top surface is constructed from a soft and smooth fabric for cleaning eyeglass lenses, and the bottom surface is constructed from a moisture resistant material. A pair of pockets are be disposed along the distal ends of the bottom surface at locations adjacent to the first and second ends. The pockets including a shape and size for receiving a thumb and finger of a user. High friction nubs are provided along the bottom surface.

A sample testing system includes a test receptacle support structure, an optical element positioned for transmitting electromagnetic radiation emitted or reflected by a sample disposed in a test receptacle supported by the test receptacle support structure, a cleaning member, and an automated transport arm configured to (i) detachably couple the cleaning member, (ii) move the detachably-coupled cleaning member into a position proximate to and/or contacting the optical element, and (iii) decouple the cleaning member.

An electric window cleaning device includes an operating portion and a wiping portion which are attracted to both sides of a glass of a window by magnets, and are free to move along the glass by virtue of balls. The wiping portion includes a power mechanism and a power supply device. The power mechanism includes an output shaft, a rotary disc and a duster removably fixed to the rotary disc. The power device includes a switch and a battery which are electrically connected to the power mechanism. When the power mechanism is turned on, the output shaft rotates the rotary disc and the duster to clean the outer surface of the glass, as an user moves the operating portion which is attracted to the inner surface of the glass, the wiping portion will also move along the outer surface of the glass to perform cleaning operation.

The present invention relates to an apparatus for cleaning a surface, in particular at solar collectors or photovoltaic installations. The apparatus has at least one cleaning head that comprises at least one cleaning member. The cleaning member is in particular a brush that can be set into rotation. The apparatus furthermore has a movement device for moving the cleaning head over at least a part of the surface to be cleaned. The movement device has a first movement unit movable in a first direction and a second movement unit. The cleaning head is movable transversely or obliquely to the first movement direction by means of the second movement unit along a guide means that is connected to the first movement unit. A control means that is arranged at the first and/or second movement units makes it possible to automatically move the first movement unit in dependence on a position of the second movement unit.

A device operable to clean an imaging element of a visualization scope comprises a visualization scope engagement body, a cleaning element having a first end portion thereof located adjacent to a distal end of the visualization scope engagement body and a cleaning head attached to the visualization scope engagement body at the distal end thereof. The first end portion of the cleaning element is engaged with the cleaning head. The cleaning head is movable between a deployed configuration relative to the visualization scope engagement body and a retracted configuration relative to the visualization scope engagement body. A centerline longitudinal axis of the visualization scope engagement body extends through the cleaning head when the cleaning head is in the deployed configuration and does not extend through the cleaning head when the cleaning head is in the retracted configuration. The cleaning element is movable for cleaning debris from the imaging element.
