Granted: 1994-05-10
Abstract: ABSTRACT OF THE DISCLOSURE:            A method of recovering copper from oxidic and/or silicate copper ores by way of pyrometallurgy. With this method, the copper ores are melted in a reaction zone heated by plasma jets and maintained at a temperature of at least 1,500°C.          At this high temperature, the thermal decomposition of the oxidic or silicate copper compounds occurs, whereas no such decomposition of accompanying metal oxides takes place. The furnace used to perform this method includes a refractory lining of carbonless material.  The reaction furnace and, thus,  the  reaction  zone  are  sealed  relative  to  the atmosphere to prevent oxygen from entering thereinto. An inert gas is used as plasma gas.

Inventor: MALLARD WILLIAM C JR
IPC: H04B3/46
Filed: 1988-06-24
Granted: 1992-04-28
Abstract: ABSTRACT OF THE DISCLOSURE      A local-area-network device (10) includes a pulse detector (40), which detects positive-voltage pulses on the coaxial cable (14) of the local-area network.  Such pulses occur when normal transmission signals reach a short circuit and are reflected.  Upon detecting a positive pulse, the pulse detector (40) turns off a transistor switch (Q12) so as to remove power from the receive lines (22) of a receiver (20) in the device (10).  Control circuitry (18) can thus conclude, from the simultaneous absences of a receive indication and of a collision indication, that a short circuit has occurred on the line.
