The maintenance apparatus has an articulated member having a first member with a handle engagement portion and a second member with a first tool engagement portion. The first member is rotationally coupled to the first member about an articulation axis. A first tool member in selective engagement with the first tool engagement portion of the second member.

An alien substance removing apparatus according to one embodiment of the present invention may comprise: a hood unit provided adjacent to an electrical steel sheet and for collecting an alien substance generated in the electrical steel sheet by laser irradiation; and a scraping unit coupled to the hood unit and scraping and removing the alien substance attached to one surface of the hood unit facing the electrical steel sheet.

A scraping apparatus, including: a gripping assembly, for gripping a stick of a cleaning tool; a bar, extending from the gripping assembly, the bar shaped to include a first section being adjacent and parallel to the broom stick, and a second section being adjacent and parallel to a brush of the broom; a scraping tip disposed at an end of the bar; and a location disposition mechanism, for manually allowing sliding the bar in relation to the broom stick and for manually disallowing the sliding against pressure applied on the scraping tip.

The present disclosure provides a nozzle cleaning device, a doctor blade replacing apparatus and a doctor blade replacing method. The doctor blade replacing apparatus includes a first doctor blade box, a second doctor blade box, a transferring assembly and a clamping and conveying mechanism. The transferring assembly includes a first tray which is disposed between the first doctor blade box and the second doctor blade box and a pushing assembly which is configured to push the first doctor blade in the first doctor blade box to the first tray and push the second doctor blade on the first tray into the second doctor blade box. The clamping and conveying mechanism is disposed between the first tray and the nozzle cleaning device for clamping and conveying the first doctor blade and the second doctor blade between the first tray and the nozzle cleaning device.

Embodiments of the present disclosure address problems presented by contaminants, such as dirt and debris, by providing an optical apparatus with techniques and methodologies for self-cleaning. In that regard, embodiments of the present disclosure employ techniques and methodologies for maintaining a very thin (e.g., few microns thick) layer of liquid, such as a non-stick liquid, on an optical window of an optical body that shields or protects an optical device.

A hardened or flexible tool created for cleaning, removing debris, preventing brush debris from being left on a surface, preventing flare ups and fires for all users of grate(s) with particular application to grates being used in grills, can be formed from a hardened material for the added cleaning ability and safety for all users of grill grates, grates, grills or the like. The handle may be of any material, shape, size, color, holes, indentions or composition and may or may not be attached by chemical bond, friction fit, snap fit, bolt on, or the like. The molding/forming, stamping, cutting creation of the device can include but is not limited to laser cutting, water jetting, molding, forming and stamping. The device can be formed from a composition which may include, but is not limited to steel, stainless steel, metal, plastic, wood, rubber, plastic and synthetics.

A deck tool has a blade edge with unsharpened bumps and an end projection. The blade fits into a gap between planks, where the unsharpened bumps permit sawing of soft gap-clogging material but do not damage structural members. The projection can hook material so that the material may be pulled from the gap or can scrape material from the top of a supporting structure. A handle of the tool may be directly held in hand and may include a feature for attachment of an extension that permits a user to stand upright while using the tool on a plank floor.

Embodiments relate to marine streamer cleaning. An embodiment provides a streamer cleaning apparatus comprising: a housing comprising an inlet configured to receive a streamer and an outlet configured to dispatch the streamer; and scraper lamellas coupled to the housing, wherein the scraper lamellas are arranged to form an opening to receive the streamer. Methods of cleaning a streamer and streamer cleaning systems are also provided.

A vehicle wiper system includes a plurality of first sensor elements, an adjustable wiper, and a second sensor. The plurality of first sensor elements is configured to be disposed at a periphery of a vehicle window to form a boundary. The adjustable wiper has a distal end and a proximal end, and an adjustment mechanism that enables a distance between the distal end and the proximal end to change. The adjustable wiper is configured to travel along a windshield to define a wiper path. The second sensor element is disposed adjacent the distal end, and is configured to operate in conjunction with the first sensor element to adjust the adjustable wiper such that a distance between the distal end and the proximal end changes, and a distance between the distal end of the wiper and the boundary remains substantially consistent as the adjustable wiper travels along the wiper path.

An aircraft windshield wiper system includes a wiper arm, a wiper blade coupled to a first end of the wiper arm, and an output shaft coupled to a second end of the wiper arm. The wiper blade includes a fluid dispensing system including nozzles, a fluid control unit, fluid lines, fluid source, and a user interface. The wiper blade with the fluid dispensing system is configured to dispense a variety of fluids directly from the wiper blade onto the windshield of an aircraft.
