Abstract: A method and apparatus for simultaneously sterilizing and lubricating a medical coupling site prior to insertion of a male luer into the site. A fiber pad is provided containing a liquid composition including a sterilizing agent and a lubricating agent. The sterilizing and lubricating agents are preferably isopropyl alcohol and silicone oil, respectively, such that application of the lubricating agent to the medical coupling site results in the alcohol evaporating to leave behind a coating of silicone oil. The silicone oil lubricates an area on the coupling site contacted by the end of a male luer.

Abstract: Coal and other particulate can be transported on a conveyor belt exposed to winter weather conditions with reduced slippage of the particulate on the belt surface by periodically treating the belt surface with from about 0.001 to about 0.005 gallons per square foot of belt surface (0.04-0.2 liters/sq. meter) of a composition consisting substantially of water soluble components comprising (A) a water soluble polyhydroxy compound or monoalkyl ether thereof, and (B) a water soluble organic nonvolatile compound having at least one hydrophilic group, (A) being different from (B). The treating composition may also include a small amount of a polydimethyl siloxane if desired.
