The present invention discloses an integrally-formed flexible rubber applicator stick, and relates to the technical field of applicator sticks. The integrally-formed flexible rubber applicator stick includes a stick body that is connected to a soft connection region at one end thereof and connected to a handle at the other end thereof; a bristle head is mounted at an end of the soft connection region, and has multiple soft rubber bristles distributed thereon; an annular discarding groove is set up between the handle and the stick body; and an anti-slip thread is set up on the end of the stick body that is adjacent to the soft connection region. The integrally-formed flexible applicator stick provided by the present invention makes the production process simple and is not prone to losing bristles during use.

A drive chain cleaning and lubricating device including an enclosure assembly, a hose assembly, a brush assembly, and a vehicle assembly is disclosed. These assemblies provide a solution for cleaning and lubricating drive chains. The enclosure assembly includes an opening at opposite distal ends to allow the enclosure body to close around a drive chain. The enclosure assembly includes a hose receiving member located opposite of each other on a top enclosure body and a bottom enclosure body. The hose receiving members can be used to supply lubricant or cleaning solution to the inside of the enclosure as well as provide drainage to the enclosure. The enclosure assembly also includes a brush assembly housed therein. The brush assembly includes a permeable brush mounted to the center of the top and bottom enclosure bodies. The permeable brush allows fluid to flow through the brush as the chain passes through the enclosure.

An adjustable tool holder is configured for interchangeable use with a variety of tools provided with different connection elements. The connection elements include at least a first connection element configured for a first manner of connection with the tool holder and a second connection element configured for a second manner of connection with the tool holder. The tool holder includes a distally extending tool support operable to detachably support each of the tools. The tool support includes a first tool connector configured to releasably connect with the first connection element in the first manner of connection. The tool support includes a second tool connector configured to releasably connect with the second connection element in the second manner of connection.

The coating device has a rotatable spindle which has fastening mechanisms for fastening a rotation axle to the spindle. Protrusions are radially protruding from the spindle for spreading the coating substance on the inner surface of a pipe. The protrusions have limiters that limit the coating substance to be spread to the desired layer thickness. The method comprises the steps of bringing, to the pipe to be treated, the coating device fastened to a rotation axle with the pipe, a feeding hose of the coating substance and a camera. The coating substance is fed along the feeding hose to a vicinity of the coating device. The coating substance is spread to an inner surface of the pipe by rotating the coating device and by moving the coating device in a longitudinal direction of the pipe.

End effectors and systems including end effectors configured to provide colorimetric indicia of a wear state of the end effector are described. In one embodiment, the end effector includes: a base portion coupleable to a motor; a chamber including an optically translucent window and a chamber interior; and a flowable material disposed in the chamber interior and having a color. The end effector is configured to provide colorimetric indicia of a wear state of the end effector based at least in part on mixing of the flowable material.

A method of delivering a glutinous substance to a workpiece from an end-effector comprises using the end-effector to rotate a brush relative to the workpiece about a rotational axis. The method also comprises, while rotating the brush relative to the workpiece about the rotational axis, urging the glutinous substance from the end-effector through a channel of a body of the brush from an axial inlet of the channel to an outlet of the channel, into contact with a thatch of bristles of the brush. Additionally, the method comprises using the end-effector to position the brush relative to the workpiece such that the glutinous substance in contact with the thatch is delivered onto at least a first surface and a third surface of the workpiece.

An application system is provided and includes a primer device configured to apply a primer, a sealer unit configured to apply a sealer and a change tool selectively connected to the primer device and the sealer unit. The application system further includes a connecting portion that is coupled to the primer device and the sealer unit, respectively to be selectively connected to the change tool. Accordingly, maintenance and repair costs may be reduced, and the required installation space may be minimized.

The present disclosure relates to an apparatus and a method for wafer cleaning. The apparatus can include a wafer holder configured to hold a wafer; a cleaning nozzle configured to dispense a cleaning fluid onto a first surface (e.g., front surface) of the wafer; and a cleaning brush configured to clean a second surface (e.g., back surface) of the wafer. Using the cleaning fluid, the cleaning brush can clean the second surface of the wafer with a scrubbing motion and ultrasonic vibration.

There is provided an applicator device (1) for applying a composition to an end of a pipe. The applicator device comprises an applicator head (3), the applicator head having a cavity (9) with an opening into which the end of the pipe can be inserted. The applicator head comprises at least one brush (10) and at least one aperture (12) for delivering the composition into the cavity, each brush having bristles which extend into the cavity (9) to wipe against the end of the pipe, each aperture being closer to the opening of the cavity than to a base of the cavity. There is further provided an applicator device (1) comprising a supplementary brush for wiping the composition over an internal surface of the pipe, a container (60) of flux composition for connecting to the applicator device, and a method of applying a composition to an end of a pipe.

A dental application device is provided having a handle having a first end, a second end, and a containment chamber disposed within the handle. The device has a dental solution disposed within the containment chamber, a receiver tip coupled to the handle at the first end, a material passage within the receiver tip that forms a conduit between the first end and a receiving end, a frangible seal that separates the containment chamber from the material passage, and a piercing cannula in fluid communication with an applicator tip and having a distal piercing end extending toward the frangible seal. The piercing cannula is moveable between a first position and a second position. When in the first position, the piercing end is spaced apart from the frangible seal, and in the second position, the piercing end punctures the frangible seal and fluidly connects the dental solution with the applicator tip.
