Abstract: A noise dampener for implementation with a sheet material dispenser is disclosed. The dampener attenuates motor and moving part noise audible to a user of the dispenser and quiets dispenser operation. In an embodiment, a noise dampener may be an integral part of the dispenser motor support structure. An embodiment of a noise dampener may include a motor support component, a motor mount component which supports a motor, and a plurality of connectors. The connectors may be integrated with and join the motor support component and the motor mount component to provide support for the motor mount component with respect to the motor support component and to provide spacing between such components collectively reducing noise audible to a user.

Abstract: A method for making a three dimensional carbon and graphite articles using three dimensional printing techniques is provided. The method includes depositing alternating layers of a binder and a filler to form an article. The filler includes at least one of carbon, graphite and combinations thereof. The article is heat treated in a non-oxidizing environment to at least about 2000° C. Another method of forming an article includes depositing alternating layers of a binder and a filler, wherein said filler includes a carbon or graphite powder in combination with a milled pitch. The binder volatizes at a temperature greater than a softening point temperature of the milled pitch, the article is heat treated in a non-oxidizing environment to at least about 800° C.
