Device to clean, disinfect and unclog kitchen, bathroom sinks drains, garbage disposals and other uses includes a cylindrical body (2), open at its two ends, provided with means for its tight fitting at the outlet (3) of a tap, includes a reducer length (21) of the diameter of the the outlet, the said body (2) being connected in turn, to a flexible pipe (4), also open at its ends, by which distal end (41) the water is expelled under pressure that can be oriented to carry out the cleaning of the sink where the tap is located in the non-accessible areas such as the overflow or the drain. A distal end (41) of the pipe (4) can be blind but incorporates several side holes (43) that radially distribute the pressurized water. A body (2) can include the diameter reducer (21) defines an internal housing (22) adapted to incorporate a bar (5) of detergent or other chemical.

The invention relates to a lubricant spray system and to a lubricant application method for treating the inner surfaces of insertion and assembly aids in a packing station. In order to efficiently treat the the inner surfaces of hollow bodies with continuous openings with the lubricant spray using the lubricant spray system, a combination of related methods and systems of the lubricant application and use in a system with directly consecutive steps is required. The lubricant spray system (1), which is equipped with a suction device, comprises a spray station (2), a mounting station (4) and a spray station (3) between which an adjustment and sliding frame element (5), designed as an insertion and mounting aid, is arranged. According to the invention, after spraying the lubricant (20), the parts to be introduced into the hollow body openings can be subsequently inserted and slidingly moved (22) in a smooth and damage-free manner A particular area of application is the packaging of battery plate packs (13) in battery containers (14).

Apparatus for spraying a material on a surface comprises at least one elongate member having a distal end and a proximal end, at least one spray nozzle mounted at the distal end of the elongate member for spraying the material in a spray pattern, the spray nozzle being connected to a spray material input at the proximal end of the elongate member, a camera mounted at the distal end of the elongate member and connected to a camera output at the proximal end of the elongate member, the camera being arranged to capture images of the spray pattern, and a control mechanism arranged to control the operation of the spray nozzle from the proximal end of the elongate member.

The gutter-cleaning device is configured for use in removing debris from a gutter. The gutter-cleaning device discharges a flow of water into the gutter that washes away the debris. The gutter-cleaning device is an extension apparatus that extends the reach of a client such that the client can discharge the flow of water into the gutter while standing on the ground. The gutter-cleaning device comprises a plurality of pipes, a plurality of fittings, a hose, and a nozzle. The plurality of fittings interconnect the plurality of pipes to form a fluid network. The fluid network is a fluid series circuit that transports water received under pressure from the hose to the nozzle. The nozzle discharges the water into the gutter that washes away the debris.

An apparatus for cleaning a surgical instrument includes an elongate member having a first end and a second end configured for disposal within a cavity of a surgical instrument. The elongate member defines a longitudinal channel and a plurality of apertures extending transversely through the elongate member. The apertures are in communication with the longitudinal channel. The first end of the elongate member is configured to be coupled to a source of fluid such that fluid passes through the longitudinal channel and out of the elongate member through the plurality of apertures.

A method for covering inner walls of a cavity with a protective layer made of anti-corrosion wax, in particular for use on vehicle bodies and add-on parts for vehicle bodies. Anti-corrosion wax is brought into an atomized form (protective agent mist) by a mist generator and supplied through an outlet opening to the cavity to be preserved. The protective agent mist is deposited on inner walls of the cavity and forms an anti-corrosion agent layer.

A method of cleaning a jet pump assembly of a nuclear reactor may comprise inserting a cleaning tool into the jet pump assembly such that a front face of the cleaning tool is adjacent to an inner surface of the jet pump assembly and below a level of a first liquid in the jet pump assembly. The method may additionally comprise directing a plurality of front jets of a second liquid from a plurality of front orifices on the front face of the cleaning tool such that the plurality of front jets of the second liquid strikes the inner surface of the jet pump assembly. The method may further comprise maintaining a standoff distance between the front face of the cleaning tool and the inner surface of the jet pump assembly during the cleaning of the jet pump assembly.

A pipe-repair tool is disclosed. The pipe-repair tool includes a first chamber to hold a first pressurized sealant and a valve to selectively allow the sealant to flow from the chamber into the interior of a pipe to be repaired. The tool may include a second chamber to hold a second pressurized sealant when using a two-part sealant, in which case the first sealant and the second sealant flow through a mixing chamber when flowing from the first and second chambers to the interior of the pipe. The valve may be a mechanical valve that is opened by moving the tool relative to the pipe to be repaired. The valve may be an electrically controlled valve that is opened with an electrical signal.

A method and apparatus is disclosed for additive manufacturing and three-dimensional printing, and specifically for extruding tubular objects. A print head extrudes a curable material into a tubular object, while simultaneously curing the tubular object and utilizing the interior of the cured portion of the tubular object for stabilizing and propelling the print head.
