668 results about "Wire brush" patented technology

A wire brush is a tool consisting of a brush whose bristles are made of wire, most often steel wire. The steel used is generally a medium- to high-carbon variety and very hard and springy. Other wire brushes feature bristles made from brass or stainless steel, depending on application. Wires in a wire brush can be held together by epoxy, staples, or other binding. Wire brushes usually either have a handle of wood or plastic (for handheld use) or are formed into a wheel for use on angle grinders, bench grinders, pistol-grip drill motors, or other power tools.

Adjustable fitting and pipe cleaning brush device

The invention outlined in the disclosure is an adjustable wire brush tool for cleaning either the inside or the outside end of a copper pipe or fitting in preparation for soldering the parts together. The tool includes a hollow cylindrical section with a first wire brush on the interior surface of the section. Attached at one end of the cylindrical section is a slightly smaller cylindrical section sized to hold a second cylindrical twisted steel brush having a hexagonal shaft that extends from the smaller section, opposite the larger cylindrical section. The twisted steel brush and attached shaft can be moved to extend the twisted brush beyond the open end of the larger cylindrical section, for insertion into a fitting to clean the fitting interior surface by attaching a power drill to the shaft and rotating the twisted steel brush attached thereto. To clean the outside of a pipe, the twist brush is retracted into the smaller section and secured to that section with an engaging means. The pipe is inserted into the larger section, and the drill is activated to rotate the shaft and attached larger section to clean the pipe outer surface. The tool overcomes the need for separate tools to perform each task and requires but one drill to perform either task as needed. The tool is sized to handle a particular diameter of pipe and fitting, with sizes ranging from one quarter inch to several inches.

Adherent, removable barrier film for tire carcass

A bond of a rubbery component to a virgin surface of a tire's cured innerliner which virgin surface has never been contaminated by the remnants of a release agent left after buffing with a wire brush and solvent-cleaning the cured innerliner, is unexpectedly stronger than a bond of the component to the contaminated but “cleaned surface”, cleaned as indicated. As an alternative, buffing with a wire brush results in a textured surface that impairs adhesion of a balance pad. Therefore, a pneumatic tire is provided with a virgin surface protected against contamination by a release agent at the curing temperature of the tire; protection is provided by a self-supporting barrier film of sulfur non-vulcanizable, expandable, thermoformable synthetic resinous material; and, a method is provided for maintaining a virgin cured surface within all or part of either the exterior or interior of a pneumatic tire's rubber carcass which is conventionally cured. The barrier film which is substantially inextensible at ambient temperature, is removable without tearing into pieces from the protected surface of the cured tire. When the interior surface is provided by an innerliner, any component to be included within the interior of the carcass may be adhesively secured to the virgin surface of the innerliner more securely than has been heretofore possible.
