Abstract: Antimicrobial formulations and coatings for medical devices and processes therefor are disclosed. The formulations include at least one water permeable polymer with at least one antimicrobial agent in a liquid medium and are prepared by wet milling the components and can form antimicrobial coatings having uniformly dispersed particles having an average size of no greater than 50 microns.

Abstract: A positive-displacement mass is introduced at the lowermost portion of an oil storage tank in order to reduce the amount of undrawable oil that remains at all times below the top edge of the suction line. It is necessary that the suction line not be occluded or interfered with and that the settled water at the bottom of the tank be permitted to be drawn off. In one aspect a tray is fitted into the bottom area of the tank and filled with water, or with inert solids, to displace the oil normally held as inventory at such location. In another aspect, a coffer dam is arranged around the suction line to permit the accumulation of water in the tank bottom, and in yet another aspect the shape and placement of the suction line nozzles are altered to improve storage efficiency.
