A device for maintaining a pneumatic conveyance line can include a body having one or more wings. In some examples, the body is configured to be positioned between opposing rails of a pneumatic conveyance track with the one or more wings positioned on a respective opposing rail of the track. The wings can carry one or more agents for at least one of cleaning and lubricating the track. As the device is pushed along the track, the device can clean and/or lubricate the track.

Disclosed is a cleaning blade, having an elastic body formed of a rubber base material molded product, and a surface treatment layer on at least an area of the elastic body to be brought into contact with a cleaning object. The surface treatment layer is formed by impregnating a surface portion of the elastic body with a surface treatment liquid containing an isocyanate compound and an organic solvent, and hardening the liquid. The surface treatment layer has an indentation elastic modulus of 21 MPa to 56 MPa. The elastic body has an indentation elastic modulus greater than 20 MPa and 35 MPa or less. The difference in indentation elastic modulus between the surface treatment layer and the elastic body is 1 MPa to 21 MPa.

A tool is provided that includes unitary plate that includes a blade portion and a tang portion. The blade portion can include an edge. The tang portion can include a positioning hole, a first hole, a slot, a second hole, a rivet hole, and one or more teeth (also referred to as one or more barbs) on a side of the tang portion. The tool can further include a hilt member which includes a through passage, a tab, and a notch. The tool includes an overlay on a body to create a handle for gripping the tool. The tool further includes a hammerhead cap on an end of the body, the hammerhead cap is coupled to the handle with a rivet through the rivet hole.

Methods and systems are disclosed for cleaning a rear view vehicle camera. An example vehicle camera cleaning system includes a camera, a blade for cleaning a lens of the camera, a fluid reservoir for dispensing fluid using gravity via a one-directional gateway valve, and an actuator for moving the blade vertically across the lens, wherein the fluid reservoir dispenses fluid responsive to actuation of the blade.

Both a system and method for cleaning a low pressure separation vessel of a high pressure polyethylene polymerization plant are provided. The system includes a polytetrafluoroethylene lining that covers the interior surfaces of the vessel, and a cover mounting assembly including an annular clamp for detachably mounting a cover over the vessel. The mounting assembly includes a clamp actuator for quickly securing and releasing the cover with respect to a top rim of the vessel. The vessel is drained of liquid polyethylene and allowed to cool to ambient temperature, thus creating a frozen skin of polyethylene around the interior surfaces of the vessel. The clamp actuator releases the cover. The polyethylene skin is peeled off the interior sides the vessel and gathered up at the top to form a neck, thus peeling the polyethylene skin away from the polytetrafluoroethylene lining along with any degraded polymers or other impurities that have accumulated on the interior surfaces of the vessel.

A treatment device for drying a laminated strip includes: lower and upper crosspieces extending transversely to and on either side of the metal strip, the upper crosspiece embedding an upper pressure cylinder with supporting rollers, the lower crosspiece embedding a lower pressure cylinder with the supporting rollers, the actuator and guide enabling the crosspieces to pass from a retracted idle position to a close working position, for which the lower and upper pressure cylinders, arranged on either side of the strip, transversely to the direction of travel, are each intended to be pressure-applied on the strip by the supporting rollers distributed along the length of the pressure cylinder, and along at least two rotating axes parallel to the longitudinal axis of the pressure cylinder. A first compartment supports all the supporting rollers. A second compartment supports the pressure cylinder. Each compartment is a removable element of the crosspiece.

The Scrape and Sweep Broom Handle Attachment is a scraping tool with special features that allow it to be quickly attached to the ends of broom and mop handles, so it doubles the effectiveness of brooms and mops as cleaning tools. Brooms and mops are some of the most commonly used cleaning tools in the world because they are highly effective at removing loose debris from floors; but when wet food and dirt dry and become stuck to floors, it often becomes necessary for people who are sweeping or mopping those floors to stop, then find other tools and get down on their hands and knees to scrape the stuck-on food and dirt loose, and then resume sweeping or mopping. When a person has a Scrape and Sweep Broom Handle Attachment on the end of their broom or mop handle though, it's not necessary for them to find another tool and get down on the floor; that person may simply turn their broom or mop around, remain standing, scrape off whatever is stuck, and then sweep or mop it away. The Scrape and Sweep Broom Handle Attachment can be quickly and easily removed from broom and mop handles to be used on raised surfaces also, such as countertops, tables, walls and windows. Because the Scrape and Sweep Broom Handle Attachment enables people to clean up faster and with less effort than when using a broom, soapy rag, sponge, or mop alone, and because it helps people maintain a greater degree of comfort while cleaning floors, it is likely to become as commonly used as brooms and mops themselves.

A snow and ice remover assembly for vehicle roofs having two vertical supports separated by a distance sufficient to move a vehicle between the vertical supports. A crossbar extends between and movable along the two vertical supports. A base structure is attached to the vertical supports and has wheels that engage a support surface upon which the snow and ice remover stands. A wheel movement prevention mechanism is also provided.

An automated surface scraping apparatus basically includes a handle formed by an elongated shaft and a hand grip attached to a rear end portion of the handle shaft, and an automated scraper head attached to a base extension mounted along a front end portion of the handle shaft. The automated scraper head basically includes a hand-operated locking-and-releasing mechanism mounted to the base extension, and a clamping jaw connected to and extending forwardly from the locking-and-releasing mechanism. The clamping jaw includes a lower jaw member, being fixed or stationary relative to the base extension and the locking-and-releasing mechanism, and an upper jaw member, being pivotally movable relative to the lower jaw member and the locking-and-releasing mechanism between engaged and disengaged orientations relative to a scraper blade.

The invention relates to a stick for the cleaning of household wastewater pipes, designed to be immobilized in the inlet of the pipe and to dissolve, under the action of the water, and release a cleaning agent. It is designed to perform mechanical cleaning in addition to the action of the agent. In order to do this, the stick is rotated under the action of the water, for example by virtue of a helicoidal relief (2) or of rotary vanes (5) on its wall.
