WASHINGTON, Dec 16 - U.S. factories, mines and utilities ramped up production sharply in November, according to a Federal Reserve report released on Tuesday showing further signs of a manufacturing recovery. The Fed said U.S. industrial production advanced 0.9 percent, its biggest monthly gain in four years. Output in the factory sector, which alone accounts for more than four-fifths of total industrial production, also posted a 0.9 percent gain. U.S. industries also operated at 75.7 percent of full capacity, their fastest pace since September 2002. Both figures were well above Wall Street expectations for a 0.5 percent gain in production and 75.3 percent capacity use rate.||
