Abstract: A handheld pressure washer device is provided that is electrically driven and does not require an external pump. The device comprises a handle section, a barrel section, and a water intake that is configured to secure to a standard water hose. The device includes a battery pack or connection to an external electrical power source, which delivers electrical power to an electric motor within the barrel section. The electric motor drives a driveshaft, which imparts rotary motion on an impeller within the barrel section. The impeller pressurizes and accelerates water within a conduit, causing the water to rapidly pass through a stator and through the outlet of the device. The speed of the electric motor is controlled by a user trigger, while the intake and outlet include coupling to affix attachments and water hoses thereto, respectively. The device provides a compact, handheld unit for pressurizing water from a hose.

Abstract: A method and system is disclosed in which an article, having large open areas or a multiplicity of apertures, is dip coated. The method and system is particularly adapted for use in coating a grid of a corona charging device utilized in the xerographic process. A transport system immerses and removes the article from a tank storing coating material. An unwanted coating material is created across the apertures of the article. Thereafter, the transport system moves the article past an ultrasonic wave source. The impact of the ultrasonic energy transmitted to the unwanted coating material across the apertures causes the removal thereof. The removed coating material is returned to the coating material in which the article was immersed.
