A sealant application nozzle comprises a manifold with a incurvate face; bristles extending outward from the incurvate face; and channels within the manifold culminating in outlets exiting through the incurvate face to dispose sealant onto the incurvate face and base of the bristles.

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.

A device for applying a liquid coating material to a portion of a fastening element projecting from a surface of a first component fastened to a second component by the fastening element. A bristle arrangement comprising a carrier structure defining an interior space and a first opening. The carrier structure comprises an annular portion extending from the first opening and extending around an entire circumference of the interior space. The bristle arrangement comprises bristles secured to the carrier structure and extending from the carrier structure into the interior space. A casing comprises an interior chamber, a second opening wherein objects are insertable from outside the casing through the openings into the interior space, and at least one through-hole providing access to the plurality of bristles and allowing introduction of a liquid coating material into the interior chamber and to the bristles. A method is disclosed for applying liquid coating material.

A plank finish applicator assembly for simultaneous application of finish to multiple planks includes a brush head to which a rod is attached. The brush head comprises a plurality of bristles having a plurality of recesses extending into its lower face and between its front and rear edges to define at least two sets of elongate bristles. At least one opposed edge of the plurality of bristles comprises a set of elongate bristles. The recesses and the sets of elongate bristles have widths substantially equivalent to those of a plank in a field of planks and a gap or a channel that is defined by adjacently positioned planks, respectively. The rod is used to dip the bristles into liquid finish and to motivate the brush head across the field to apply the liquid finish to upper and opposed side facets of the planks.

A notched fluid applicator comprising a base with a dispenser pad or a brush. The notch allows the application of a fluid to a surface containing one or more protrusions. The applicator may be used to apply fluid to the surface of an article such as a glass substrate, printed circuit board, or other surface containing one or more protrusions.

A portable coating applicator kit preferably includes a liquid jug, an applicator brush, and a surface coating liquid. The liquid jug preferably includes an integral handle, a pour spout and a removable cap. A brush opening is formed through a side wall of the liquid, such that a small amount of surface coating liquid may be retained in a bottom of the liquid jug. A height of the brush opening is sufficient to allow the plurality of bristles to be freely inserted into the brush opening to coat tips thereof with the surface coating liquid. The brush preferably includes a brush handle and a brush tether. The brush tether extends from a free end of the brush handle. The brush tether preferably includes a flexible line and a hook. The hook is preferably large enough to hook around a bottom of the integrated handle.

A method and apparatus for processing a lithographic printing plate precursor, comprising development with a first gum solution and subsequently with a second gum solution, wherein both gum solutions are provided in a cascade configuration whereby the second gum solution overflows into the first gum solution and the development is combined with mechanical rubbing and/or brushing by one or more flat brushes.

A squeezable dispensing container for accommodating and applying liquid adhesive includes a main body having a nozzle with a dispensing orifice therein and a separate brush applicator including a brush that is selectively connectable to the nozzle. To enable selective connection of the components, the nozzle tip and the brush applicator can form a cooperative coupling structure. To dispense the liquid adhesive, the brush applicator may include a ferrule defining a channeling bore establishing fluid communication between the dispensing orifice and the proximate end of the brush retained in the ferrule. The liquid adhesive may flow through or around the brush to the surface or substrate to which it should be applied.

A lubricant application device includes an application brush configured to apply a lubricant to a surface of an application target by bringing brush bristles into sliding contact with the surface while the surface of the application target is being rotated. The application brush is configured to come into pressure contact with and separate from the application target, and the application brush is configured to come into pressure contact with and separate from the lubricant.

A portable pipelining assembly featuring a dual pump system and a brush system for simultaneous delivery and application of multiple liquids is disclosed. Each pump system includes a motor-driven pump connected to a dedicated reservoir for storing distinct liquids, with fluid conveyed through individual hoses and output valves. The brush system, attached to a delivery end of both hoses, comprises a motorized handle base with dual conduits that channel each liquid to rotating brushes. The brushes, powered by a secondary motor, enable concurrent dispensing and mechanical treatment of surfaces using two separate fluids, enhancing pipelining efficiency. The distinct liquids can be an epoxy resin base and an epoxy catalyst, that when mixed together form an epoxy resin used for lining cast iron pipes.
