A method for cleaning a receiving groove formed on a rotor of an axial flow machine, the receiving groove serving to receive a blade root of a rotor blade is provided. In the method, an elongate base body of a machining tool, the base body having an abrasive surface at least in regions, is introduced into the receiving groove and therein is moved back and forth while machining is performed, wherein the outer contour of the base body is adapted to the contour of the receiving groove to be cleaned, in such a manner that when the base body is in the state inserted in the receiving groove it contacts the wall of the receiving groove in a substantially form-fitting manner such that it acts as a guide body during the back-and-forth movement. Also provided is a machining tool for carrying out the method.

Generally, a panel maintenance system including a panel maintenance assembly configured to move over a plurality of panel modules. Specifically, a panel module including a first frame including a first plurality of frame members joined to enclose a first panel. The first plurality of frame members including a first frame inner side configured to capture the first panel within the first frame and a first frame outer side configured to provide a first track axially extending between first and second ends of at least one of the first plurality of frame members. The first track configured to engage a drive element of a panel maintenance assembly which operates to move the panel maintenance assembly over the first panel. The panel maintenance assembly bears one or more components which function to maintain the first panel.

A tool for a slot in a gas turbine engine, according to an example of the present disclosure, includes a head configured to be received in the slot, a first pad removably bonded to the head with an adhesive, and a second pad removably bonded to the head with an adhesive and disposed opposite from the first pad.

A cleaning system and method can include a leading carriage assembly attached to a brush assembly and can be configured to drive the brush assembly. A trailing carriage assembly can be configured to move along a track. The trailing carriage assembly can be attached to an arm. A vertical support rod can be partially disposed within the arm and can be attached to the brush assembly. A height of the vertical support rod can be positioned by one or more clamps located around the vertical support rod.

In some variations, this invention provides an electro-mechanical device for automated cleaning validation of a selected surface. The device moves a wetted swab over a cleaned surface to recover any remaining soil left over from the cleaning process. The device accepts a standard sampling swab that has been wetted with the required liquid solution. The device maintains constant swab pressure to ensure maximum recovery of soil or contaminants. The device includes an electronic controller for adjusting the movement of parts to effectively validate cleaning of the selected surface. The surface to be validated may be a substantially flat surface, or rounded. The surface may be contained within a vessel, reactor, a pipe, tank, or other equipment. The device may be disposed on an extension arm to allow the device to be positioned appropriately, without the need for a person to be close to the device for validation.

The application discloses an improved wheel pretreatment rack. The wheel pretreatment rack includes a hook, tripods, positioning slide blocks, positioning holes, a main rod, bearing rods, braces and positioning clamping jaws. Compared with the traditional wheel pretreatment rack, the improved wheel pretreatment rack in use has the advantages that the requirement of wheels having different sizes for the pretreatment rack is met by adjusting the positions of the bearing rods up and down, and the problems of drop, scratch and the like in the cleaning pretreatment process of the wheel may be effectively prevented by a wheel three-point-fixing mode.

A wiping device for wiping an optical element clean of water or of particles includes a housing and a wiping element able to undergo a movement with respect to the housing, where the wiping device is configured to move in such a manner that such movement is caused by coupling a first unit in or on the wiping element with a second unit in the housing via a time-variable electromagnetic field. The wiping device may be used for wiping the surface of a lens or of a window, which lens or window is transmissive to visible light, ultraviolet radiation, and/or infrared radiation, and is preferably placed in front or as part of a camera. In addition, a rear view device or driver assistant device for use in or on a vehicle including such a wiping device, and a method for wiping an optical element are provided.

This invention discloses a bacteria-controlling and stain-removing system for handrails in public places, including clamping blocks of bilateral symmetry, a moving mechanism arranged in the clamping blocks, and the movable mechanism includes two symmetrical top wheels; the top wheel can move up and down along with the size of the handrail; a transverse rotating wheel is arranged in the clamping block, and the handrail can be clamped through the transverse rotating wheel, so that the device can move along the handrail, and a driving mechanism is arranged on the moving mechanism, so that the overall linkage is high, and one-time repeated movement can be automatically completed on the handrail, spraying the sterilizing liquid uniformly on the handrail, wiping residual bacteria removing liquid, and maintaining the cleanness of the handrail, the size and the width of the handrail can be adjusted, the internal size can be automatically adjusted by the device.

Methods and apparatus for cleaning a central venous catheter port are disclosed. An apparatus includes a body, a coupling configured to connect the body to the hub, a cleaning cap coupled to the body, and an actuator disposed within the body for rotating and translating the cap relative to the hub. The cleaning cap includes a cap body defining a cavity and a cleaning member disposed within the cavity, the cleaning member having threads that engage with the threads on the hub.

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.
