    Abstract: A DC feedback control circuit for compensating for a DC voltage level shift in a transimpedance amplifier circuit having a transistor as a high speed switching device. The DC feedback control circuit includes a filter for determining a DC voltage level at an output of the amplifier circuit and a differential pair of transistors for comparing the DC voltage level with a reference voltage. A pair of current mirrors mirror a current dependent on the comparison of the DC voltage level with the reference voltage and apply the mirrored current to an emitter of the transistor so as to maintain a substantially constant bias current through the switching transistor.

    Abstract: A continuous adhesive applicator for applying adhesive, sealant, or the like to cans as they travel along an automated processing line. The apparatus moves the cans through the station area while holding the cans in a selected orientation, rotates the cans as they move through the station, and applies adhesive or the like to a selected portion of each can as it moves through the station. Restraining means, which are cycled for repetitive movement through the station along the path of travel of the line of cans, capture the cans and move them through the station while holding them in the selected orientation.

    Abstract: A new class of releasable corrosion inhibiting materials for protective coatings, methods of making the same, methods of using the same, and coatings containing the same are provided. The materials comprise one or more corrosion inhibitors that are chemically anchored to the surface of a particle having an aluminum oxyhydroxide surface through a carboxylate bond. The carboxylate/aluminum-oxyhydroxide-surface bond breaks under corrosion-causing conditions (for example the presence of high levels of hydroxide ions generated by the cathodic oxygen reduction reaction on metals such as iron and aluminum) thereby allowing the corrosion inhibitors to detach from the particle surface when corrosion is present.
