An insect nest removal assembly includes a telescopic pole that has a fluid coupling at one end, a head coupling at another end, and a sealed hollow interior extending an entire length between the fluid and head couplings; a head connected to the head coupling that includes a blade, a brush, and a passage in fluid communication with the sealed hollow interior of the telescopic pole and the brush; and a fluid control valve connected to the hollow interior of the telescopic pole.

A cleaning device includes: a lens cover configured to cover an object lens of a camera provided in a machining area of a machine tool, the lens cover being transparent; a motor configured to rotate the lens cover; and a wiping member configured to, when the lens cover rotates, wipe at least an adhering substance that has adhered to a region of the lens cover in an angle-of-view of the camera.

A wear element is disclosed that includes at least two layers of a structural material and at least one layer of a non-solid metal material, wherein the non-solid metal material includes a non-homogenous edge for contacting a roll surface.

A biological information measurement apparatus comprises: a spectrometer; a housing that contains the spectrometer and includes a surface on which a measurement target is to be placed, and an aperture portion through which light illuminating the measurement target placed on the surface and light reflected from the measurement target are to pass; and a shutter member that can move between a first position of opposing the aperture portion of the housing and a second position of retreating from the first position of opposing the aperture portion, the shutter member including a white reference surface. If the shutter member is at the first position, the spectrometer performs calibration using the white reference surface. If the shutter member is at the second position, the aperture portion and the measurement target oppose each other, and the spectrometer colorimetrically measures the measurement target.

The invention relates to a cleaning device for a yarn forming element of an air-spinning nozzle, to a spinning position of an air-spinning machine and to a method for cleaning a yarn forming element of this type. In order to provide a spinning position of an air-spinning machine and a method for cleaning a yarn forming element of an air-spinning machine which allow long and trouble-free operation with constant quality and strength of the yarn produced, it is provided that the cleaning device has a cleaning strip and a storage unit for providing and retracting the cleaning strip, a fixed end of the cleaning strip being fastened to the storage unit, and a free end of the cleaning strip being able to be provided for cleaning and retracted again after the cleaning. Furthermore, the cleaning device has a cleaning strip guide for feeding the free end of the cleaning strip to the yarn forming element of the air-spinning nozzle for mechanical cleaning.

Both a system and method for cleaning a tow 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.

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.

A cleaning device having a handle and one or more cleaning members. A first of the cleaning members has a first finger, a second finger spaced apart from the first finger, and a compliant member extending from the first finger to the second finger. The compliant member is constructed at least partially from a metallic material. The first finger is spaced from the second finger to accommodate a cross-member of a cooking grate between the first finger and the second finger such that the compliant member contacts the cross-member. A second of the cleaning members has an elongation and a first bar and a second bar extending transverse to the elongation, the second bar spaced from the first bar along the elongation. The second of the cleaning members is configured to be inserted between adjacent cross-members of a cooking grate and, after insertion, rotated.

The improved double-sided convex mirror cleaning tool disclosed herein may comprise, at least, a fixed, concave cleaning blade and a handle. Such a device contemplates the use of resilient and flexible materials for the cleaning blade suitable for use in cleaning windows, and resilient and solid materials suitable for structural rigidity in the device main body. The combination is unique in that the cleaning blade is a concave blade meant to contour most effectively with convex mirrors commonly found on tractor-trailer combinations. The device may further comprise a second, straight cleaning blade for use in the cleaning of planar mirrors, or may instead comprise a variety of attachments suitable for providing additional functionality to the device.

The invention relates to a wiping device (1) for a motor vehicle window (30), comprising a windscreen wiper frame (10) and a piezoelectric film (2), said piezoelectric film (2) being mounted on the windscreen wiper frame (10) such as to produce an electric current. The invention also relates to a warning method and a spray control method for such a wiping device (1).
