Abstract: ABSTRACT A full wave rectifier includes an operational amplifier having a non-inverting grounded input, an inverting input and an output.  A first resistor is connected between the inverting input and the input terminal of the rectifier and a second resistor having the same resistance as the first resistor is connected between the inverting input and the output terminal of the rectifier.  These two resistors serve as a gain setter for the rectifier. A depletion type MOS FET is connected between the output of the operational amplifier and the output terminal of the rectifier.  The invention increases the rectification range achieved by conventional rectifiers which use a diode at the output of the operational amplifier.  The invention also allows the rectifier to be made using an MOS integrated circuit technique.

Abstract: ABSTRACT            The present invention relates to a method for treating iron-bearing slags containing precious metals, parti-cularly slags created in copper and nickel smelting processes, by reducing the slag so that by means of adding a possible sulphidizing agent, the composition of the molten slag is regulated in solidified state to fall within the area wherein the metallicized, iron-bearing molten copper sulphide is in balance with the metallic copper and the iron-base metal alloy.  By means of controlled cooling, the precious metals contained in this molten sulphide having an advantageous liquidus temperature are concentrated into the iron-base metal phase, whereafter the phase containing the precious metals can be separated by means of magnetic separation. After the magnetic separation, a selective hydrometal-lurgic treatment is carried out in order to recover the precious metals.

Abstract: ABSTRACT OF THE DISCLOSURE       A heat flux meter for measuring heat flux in a hot environment, such as, a coal-fired boiler, includes a  cup-shaped  body  member  of  one-piece  construction having an internal cavity in which is mounted an annular thermoelectrically-dissimilar member from that of the body member  and  in heat and electrically  conducting contact with the body member.  Electrically conducting wires of the same metal as the annular member enter the cavity and are connected to the centre of the circular portion of the body member and to the annular member.          An e.m.f.  is induced by the difference in temperature between the centre of the disc portion and the annular member.   Since  the  body  member  is  of  one  piece construction and the heat flux meter is sealed to the walls of the boiler,  gases  from the hot environment cannot enter the cavity and cause failure of the meter.
