Abstract: The present invention relates to a web handling apparatus and process ideally suited for applications involving wet chemistry. The invention involves the horizontal processing of webs in processing containers. The web is redirected into the processing container by inserting a cassette across the web and into the processing container. The cassette includes at least one functional fluid element that facilitates processing of the web. The web handling practices of the invention improve the quality of the processed web. The invention is preferably used in electrodeposition processes.

Abstract: A spatial notch filter is described that adapts in accordance with changes to an angular velocity of a rotating component within a manufacturing system. In a manufacturing system, noise may appear in feedback signals due to spatially distributed physical features in the system, such as imperfections in the components or sensors. This noise may be concentrated in a frequency band that changes as the angular velocity of rotating system components changes. The invention provides techniques for filtering this noise with one or more notch filters, and for adapting the center frequency of the notch filter as a function of angular velocity. The center frequency of the notch filter tracks the noise when the noise frequency changes.
