Title: Method for reducing iron ore.
IPC: C21B13/02
Filed: 1984-05-16
Abstract: A method for the gaseous reduction of iron ore to sponge iron in a vertical shaft moving bed reactor (10) wherein a hot gaseous mixture of hydrogen and a carbon monoxide is used to reduce the ore. It has been found unnecessary to use the external catalytic reformer of prior art processes to reform the methane and other hydrocarbon constituents of the natural gas commonly used as a source of gaseous reductants. By establishing a reducing gas recycle loop to which make-up natural gas and steam are fed in the proper proportions, the product sponge iron in the reactor (10) can be used to catalyze hydrocarbon reformation, provided that the carbon content of the recycled gas is maintained low by removing carbon dioxide therefrom. When pure methane is employed, steam/methane molar ratios within the preferred range of 1,4 : 1 to 2.2 : 1 are used.

Title: DS-O Loop-back detection on a DS-1 line
Inventor: O'CONNELL ANNE
IPC: H04J3/12
Filed: 1992-10-21
Abstract: Loop-back detection and signalling is achieved on any DS-0 channel that conforms to 56 kbps operation such as DDS in a DS-1 digital data transmission system. A standard DS-1 chip set (line interface unit, framer, and link layer controller) is used, coupled to 24 transmit and receive buffer means in the customer main memory. The framer detects control bits by using Channel Associate Signalling, (designed for digitising voice in-band signalling and not normally used for data transmission), in the incoming signal and interrupts the customer CPU, which determines from the framer which channel caused the interrupt, changes the mode of the relevant channel, checks that channel's receive buffer means for loop-back codes, and, if enough successive loop-back codes are found, copies the receive buffer means into the transmit buffer means (with code mapping) for as long as the loop-back condition exists.
