An apparatus for transporting single sheets through a device for exposing or printing the single sheets, with a drum and means that press the single sheets against the drum, with a processing station having a processing gap, with the single sheets being exposed or printed in the processing station, includes means that limit the processing gap. The invention also relates to pharmaceutical formulations of said compounds, methods of treatment using said compounds and to processes for the preparation of said compounds. The set of set of instructions further causes the computer to calculate a first measure of correlation from the comparison, scale a first strain data set of the first pair of strain data sets if the first measure of correlation is above a correlation threshold, and display the scaled first strain data set to a user. The device has a second substrate with at least one or more deflection devices thereon coupled to the first substrate. The filter cartridge can be positioned within the guides during maintenance of the aquarium. Thin electrodes of anode and cathode of this novel emitter are not coplanar, instead they are placed on 2 intersecting surface and anode-cathode fissure is placed on top or near the top edge of these two intersecting surfaces.
