Abstract: In one embodiment, a sample probe has a cap and a base, wherein the cap includes a grip portion and a projection portion. The projection portion fits within a hollow portion of a filter such that the filter is disposed on the outside of the projection portion and the filter and the cap form a cap assemblage. The base comprises a base recess that receives a portion of the cap assemblage including the filter. The cap and base include corresponding media transfer regions adjacent and connected to the filter that reduces flow resistance and chances of blockage and/or contamination during dissolution-testing sampling using the sample probe.

Abstract: A feeder for supplying sheetlike items such as envelopes or the like to a processing machine such as an office printer. The feeder may employ a pickup such as a coil for detecting a change in magnetic field to thereby detect operation of an intake device in the processing machine. The feeder may pass an item downstream into the processing machine in response to such detection. The feeder may be arranged to move each item into a ready position and then advance each item downstream from the ready position while permitting realignment of the item by the processing machine.
