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.

The invention relates a powder brush, which includes a body having mounting means for mounting a powder cartridge thereon and a brush head assembly attachable to an operative front end of the body. The brush head assembly defines a bristle mounting means capable of retaining a plurality of circumferentially arranged bristles therein. Furthermore, the powder brush includes a powder dispensing arrangement, in use, operable selectively to dispense powder from the powder cartridge onto the plurality of bristles. The dispensing arrangement includes an agitator disposed inside the powder cartridge, which cartridge includes a biasing means operable to bias the agitator towards a closed and open position. The bristles comprise of features, in particular, ostrich feathers of which a stem portion is secured to the brush head assembly.

A tire shine application system includes a computer having at least one sensor interfaced thereto that detects and measures sizes of a tire of a vehicle as the vehicle enters a car wash. A tire shine applicator is interfaced to a three-directional movement device that is controlled by the computer. When the tire approaches the tire shine applicator, the computer controls the three-directional movement device to position the tire shine applicator to an outwardly facing wall of the tire and controls the three-directional movement device so that the tire shine applicator traverses the outwardly facing wall of the tire while tracking the tire as the tire shine applicator deposits tire shine liquid on the outwardly facing wall of the tire.

Disclosed is a new method, and a system, for increasing the pH of a composition applied on teeth and/or gums. The composition is gelable under the influence of a pH change. The pH change typically is a pH increase in the event of a direct pH-triggered gelation. The pH change typically is a pH decrease in the event of gelation induced by ions, such as calcium ions, released from a pH-sensitive carrier. The device comprises a dispensing unit for the composition, a distal end of which is adapted to apply said substance onto teeth or gums. The device further comprises an electrode system comprising first and second electrodes, the first electrode being adapted to be held against the composition at a location at or near teeth or gums, and the second electrode being adapted to be held against the composition at a location away from teeth or gums, The electrode system is adapted so as to provide an electrical potential difference of 1.5 to 10 Volt between the electrodes.

An applicator for a container, the container for storing a substance to be applied and including an outlet through which the substance is to be discharged, wherein the applicator includes a brush head adapted to be located at the outlet; and a removable nozzle adapted to be optionally mounted over the brush head.

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.

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.

A fluid applicator for applying a fluid to a surface protrusion. In one embodiment, an anticorrosion substance is applied to a structural fastener.

An applicator device for applying a fluid to an object has a hollow body, an applicator, a sensor, and a notification system. The hollow body stores the fluid therein. The applicator discharges the fluid. The sensor is configured to detect a fluid surface of the fluid. The notification system is configured to generate a notification signal based on a detection signal from the sensor.

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.
