The tool additionally includes a blade having first and second ends, an indent in a bottom surface of the blade near the first end for engaging the detent in a closed position, and a ramp on the bottom surface near the indent defining a reduced thickness portion of the blade that reduces in thickness from the indent towards an edge of the blade to reduce contact between the detent and the blade during rotation of the blade.

An automatic cleaning device for a ring hammer crusher, and a ring hammer crusher having the automatic cleaning device are provided. The automatic cleaning device includes an automatic cleaning assembly at a back side of a feeding opening of a crushing chamber of the ring hammer crusher; the automatic cleaning assembly includes a material meeting disk and a cleaning blocking rod; the material meeting disk is connected to a drive member and is driven by the drive member to rotate, and the cleaning blocking rod is fixed to the crushing chamber and is cooperated with a material meeting surface of the material meeting disk for cleaning. The ring hammer crusher having the automatic cleaning device has a simple structure and convenient operation, thus improving cleaning effect.

A system includes a sensor base, a sensor cover having a window that is rotatably mounted to the base. The system includes a contacting cleaner and a contactless cleaner. The system further includes a processor that is programmed to actuate, first, the contactless cleaner and, then, upon determining that opacity of the window exceeds a predetermined threshold after actuation of the contactless cleaner, the contacting cleaner.

A hand tool includes a handle and a connection portion which is connected to the handle. The handle is a hollow handle and has a space defined therein. The connection portion includes a slit. A blade has a body and a toothed portion which is inserted into the slit of the connection portion when the handle and the connection portion are connected to each other by way of blow molding. A cooling material is located in the space of the handle. The temperature of the cooling material is the same as the temperature of the handle and the connection portion during blow molding. The cooling material contacts the inside of the handle to cool down the handle. The cooling material performing as a weight in the handle 2.

Described is a self-cleaning extrusion orifice assembly including an enclosure, a cylindrical body inserted into the enclosure and terminated by an extrusion orifice. The self-cleaning extrusion orifice assembly is operated by a pressurized air flow. The pressurized air flow flushes surfaces of some elements of self-cleaning extrusion orifice assembly removing debris that could be deposited on these surfaces. In addition, some elements of self-cleaning extrusion orifice assembly are configured to scrape extrusion process debris from the same surfaces.

The present wire brush is adapted to clean a grill grate and basically comprises and outer housing, a grate-engaging flange, a flexible bristle-receiving retainer and a plurality of wire bristles. The outer housing has upper and lower portions. The grate-engaging flange extends from the lower portion of the housing in generally perpendicular relation thereto. The flexible retainer is disposed in the upper portion of the housing. The bristles have upper portions embedded in the retainer and grate-engaging free ends that extend no more than one-half inch beyond the grate-engaging flange.

A method of cleaning wafer-cleaning brushes includes passing a wafer having a first polished main side and an opposing unpolished backside between a pair of substantially cylindrical shaped wafer-cleaning brushes are rotated about an axial direction of the brushes while passing the wafer between the pair of wafer-cleaning brushes. A cleaning solution is applied to the brushes while passing the wafer between the pair of wafer-cleaning brushes. While passing between the pair of brushes, the first polished main side of the wafer faces a first direction, the first direction is an opposite direction to which a polished side of a production wafer faces during a subsequent polished wafer cleaning operation. The substantially cylindrical shaped wafer-cleaning brushes include a plurality of protrusions on an external surface of the brushes, and the brushes contact the wafer at least a portion of time the wafer is passing between the pair of brushes.

The invention discloses an anti-blocking device for a field channel, a fixed plate which is symmetrical back and forth, and comprises a front and back symmetry fixing plate, the lower end of the fixing plate can be fixed to the two sides of the canal channel of the canal, a transmission box is fixedly connected between the fixed plates on the two sides, a transmission device is arranged in the transmission box, and a cleaning device is arranged on the lower side of the transmission case, the device is simple in structure, a plurality of devices can be arranged on the canal channel, the cleaning efficiency is improved, the device can automatically clean the channel in the canal channel, avoid blockage of the channel after a long time, can collect sundries, and does not need manual cleaning, and the collected sundries are taken out by only human timing.

In an example, a wiper system includes a first wiper blade, a second wiper blade, and a cam. In that example, the cam is coupled to the first wiper blade to move the first wiper blade to a first wipe position when the cam is in a first cam position and coupled to the second wiper blade to move the second wiper blade to a second wipe position when the cam is in a second cam position.

The present disclosure relates to a bottle treatment machine including a pump/nozzle protector in the form of a screen. The screen includes an at least partially perforated surface and the screen is provided for passing a liquid of the bottle treatment machine therethrough. The bottle treatment machine further includes at least one scraper which rests at least partially on the at least partially perforated surface of the screen. The screen and the at least one scraper are arranged to be rotatable relative to one another. The present disclosure further relates to a method for cleaning the screen of the bottle treatment machine.
