FILE - In this Thursday, Sept. 6, 2012, file photo, workers form a large spindle at Solmet Technologies in Canton, Ohio. U.S. industrial production increased only modestly in September, held back by weak growth in factory output. The Federal Reserve says U.S. industrial production rose 0.4 percent in September after a 1.4 percent decline in August. The August decline partly reflected precautionary shutdowns before Hurricane Isaac hit the Gulf Coast. (AP Photo/Mark Duncan)
