A metal hand tool including a handle attached to a blade piece and method of construction. The blade piece includes a blade opposite an elongated tang. The handle is made up of two, welded, symmetrical handle halves, each handle half having an opening for receiving a hang hole piece and a notched distal end for forming a handle opening to receive the blade piece elongated tang. In an embodiment, the handle includes a curved distal end accommodating a curved welded connection between the blade piece and the handle. The hand tool further includes a hang hole piece configured for placement through the hang hole openings in the handle and for welded connection to the handle. In an embodiment, the elongated tang includes a hang hole opening through which the hang hole extends. Some embodiments further include one or more tang guide pieces welded to the interior of the handle.

A curved target substrate cleaning system includes a pressure-type cleaning unit for cleaning a cleaning area of a target substrate having a curved surface by applying pressure to the cleaning area, a support body detachably supporting the pressure cleaning unit at a predetermined height with respect to a cleaning area of the target substrate having the curved portion, a cleaning area flat maintaining unit that clamps one end of a target substrate having a curved portion and adjusts a height of the curved portion to maintain the cleaning area of the target substrate in a predetermined orientation with respect to the pressure-type cleaning unit, and a moving unit that moves the cleaning area flat maintenance unit back and forth in one direction with respect to the pressure-type cleaning unit.

A scraping device to be used for an applying system has a nozzle which is formed such that an outer wall surface is tapered toward a distal end. The scraping device includes: a pair of scraping units, each of which has a corner portion for scraping a viscous material adhering to the outer wall surface; and a driving unit which causes the pair of scraping units to approach to and separate from each other. The nozzle is movable to be temporarily arranged between the pair of scraping units. The pair of scraping units move to approach to each other when the nozzle is arranged between the pair of scraping units, and approach to each other until the corner portions abut each other due to movement as retraction of the nozzle from a portion between the pair of scraping units.

The present invention relates to an apparatus for processing a film by a squeezing force, including a stand, a soaking tank, as well as a feeding shaft, a roll shaft, a stepping motor and a scraping mechanism mounted to the stand, respectively, wherein the rotatable pressure roll shaft presses the film to the soaking tank; the scraping mechanism includes a first scraping shaft and a second scraping shaft which are connected to the stepping motor; an optocoupler switch is fixed to the stand; the stepping motor automatically finds the initial position via the optocoupler switch; and the stepping motor automatically adjusts the position and angle of the scraping mechanism according to a parameter.

The present disclosure relates to a negative ion generating device and an air purifier. The negative ion generating device includes a housing, a negative ion assembly, and a cleaning assembly. The negative ion assembly is arranged to the housing, and the negative ion assembly includes a conductive fiber brush. The cleaning assembly is arranged to the housing, the cleaning assembly includes a driving mechanism and a cleaning member, and the cleaning member can move under action of the power provided by the driving mechanism, and contact or separate from the conductive fiber brush during movement.

A cleaning device includes a blade, a support plate for supporting the blade and a reinforcing plate fixed to the support plate. The support plate is provided with a first flat portion and a first one end portion and a first the other end portion of the first flat portion. The reinforcing plate is provided with a second flat portion disposed along a longitudinal direction so as to be along the first flat portion, a second one end portion and a second the other end portion of the second flat portion. As viewed in the longitudinal direction, the second one end portion is provided with a projecting portion projecting from the second flat portion in a first direction crossing a short side direction and the first the other end portion is provided with a support plate projecting portion projecting in a second direction opposite to the first direction.

The present disclosure discloses a process measuring device for determining one or more physical and/or chemical process variables, comprising a sensor element for measuring the process variable and a cleaning device for cleaning deposits and accretions on an end face of the sensor element, wherein the cleaning device has a plurality of rotatable cleaning arms which are arranged to be rotatable and pivotable about the same axis of rotation.

An automatic touchless washing machine is used for washing and cleaning all various types of buildings and windows. The machine dispenses, by a spray arm, high pressure water, chemical liquid, or dry-air from various storage tanks to wash areas of exterior surfaces of a building or a window. A controller controls the machine to automatically perform a wash program, step by step, without using hands. The controller further controls one or more wash functions by coordinating movements of the spray arm.

Disclosed is a mop bucket, including: a bucket body, having a chamber with an opening at a top, wherein the chamber is provided with first and second partition plates to separate the chamber into a dirty water chamber, a movable chamber, and a clean water chamber; a mounting frame, mounted at the top of the bucket body and provided with a first operation opening communicated with the movable chamber; and a cleaning mechanism, including a first scraper plate provided above the first partition plate and inclined toward the dirty water chamber, a water supply assembly, and a water spray pipe provided above the first scraper plate, wherein the water supply assembly is used to communicate with the clean water chamber and the water spray pipe to spray clean water toward the mop in the movable chamber by the water spray pipe. The practicability of the mop bucket is effectively improved.

A system for coating removal is disclosed. The system may include at least one induction head. The at least one induction head may be electrically connected to a power supply wherein the power supply and the at least one induction head are configured to deliver energy to the coating at an energy density level at or above an incineration threshold for the coating. The system may also include a vacuum system configured to extract at least a portion of the coating, including incineration products generated by delivery of the energy to the coating.
