An improved hand held apparatus used for dusting, cleaning, polishing, and similar tasks utilizing a lightweight conventional power drill having a rotating axle with a chuck to which is attached one or more elongated extension members telescoped within one another and fixed relative to one another by a clamping connector, the first extension member having a first connecting member at one end constructed to be inserted into and attachable to the chuck and a second member at the opposing end of the extension members constructed to be attachable to the head of a conventional dusting device. The apparatus further includes a foam covered tubular hand guide member fitted about the first extension member and constructed to slide along the first extension member. The first connecting member is constructed having a shield to prevent water from dripping down the extension members and into the power drill, and to prevent the guide member from sliding off the extension member when the extension member is not attached to the power drill.

An exterior material may be configured to form an exterior of a home appliance, the exterior material includes a base material having a hierarchical circular structure pattern on the surface. The hierarchical circular structure pattern may include a plurality of circular structures having diameters different from each other, and a pattern density may be, in percentage of area of the surface, about 20 to 90%.

Polishing media in the form of bristles made from a porous polymer-based material, apparatus and systems including the media, and methods of forming and using the media, apparatus, and systems are disclosed. A method of manufacturing bristles for use in polishing a workpiece which includes a non-planar surface includes the steps of combining a liquid polymer material and a foaming agent to form a foamed polymeric material, and separating the foamed polymeric material into a plurality of bristles. The foaming agent is configured to impart a porosity to the polymeric material, where the porosity is characterized by a density in the range of 0.3 to 1.2 g/cm.sup.3.

A grinding or polishing brush is provided and includes a main body which is rotatable about a central axis and is provided with bristles which extend with their center axes substantially in the direction of the central axis. In order, with such brushes, to permit pin point working, it is proposed that the center axes of the bristles have an inclination in the circumferential direction and/or inward in the radial direction. The effect which can therefore be achieved with the bristles is that they are supported against one another. In order to improve this, the bristles can be provided in an axial portion with film elements connecting them. The film elements may be able to come apart depending on wear.

Described herein is an oral care implement that includes a head portion; a cup member extending from a front surface of the head portion along a first axis, the elastomeric cup member comprising: a top surface; a plurality of grooves formed into the top surface; a plurality of rib members, wherein adjacent ones of the grooves are separated by one of the rib members, each of the rib members extending along a rib axis that extends radially outward from the first axis, and wherein each of the rib members has a thickness that increases with distance from the first axis. The cup member may comprise a plurality of first grooves and a plurality of second grooves, and wherein each of the first grooves has a first transverse cross-section and each of the second grooves has a second transverse cross-section, the first and second transverse cross-sections being different from one another.

A honing brush is provided comprising a brush hub having a face wherein the face has at least one or a plurality of two or more outwardly projecting bristles having a length that is from about 15 millimeters to about 25 millimeters, a grit size of about or greater than 240 grit to about 800 grit, a diameter of from about 0.2 millimeter to about 0.8 millimeter, and wherein the plurality of bristles are arranged in either a non-tufted bristle arrangement or a tufted bristle arrangement, and wherein each of said bristles is made of a polymer material.

Brushes for cleaning wafers after a Chemical Mechanical Polishing (CMP) process and methods for fabricating such brushes are provided. An exemplary method for fabricating a brush for cleaning wafers after a Chemical Mechanical Polishing (CMP) process includes forming a brush configured for contacting the wafers; and, while forming the brush, controlling formation of pores within the brush to a maximum pore dimension, wherein the maximum pore dimension is 1000 nanometers (nm).

The brushing device contains a bundle of fiber rods (1), which are arranged parallel to one another, and a protective sleeve (2), which encloses the fiber rods. Once fiber rods (1) have become worn, the protective sleeve (2) is able to be axially adjusted, so that the free ends of the fiber rods (1) protrude beyond the protective sleeve (2) by a desired amount. A first component (4) connected to the fiber rods (1) and a further, second component (8) connected to the protective sleeve (2) are detachably connected to one another, in a non-positively locking manner, by a clamping mechanism (3, 5, 11).

The present invention is concerned with an electric utility brush having a flexible drive shaft, and in particular an electric toothbrush having a substantially spherical head mounted on the flexible drive shaft and which can be driven rotationally in at least two different orientations in order to provide comprehensive brushing capabilities.
