Abstract: Leaching of gold and/or silver from ores or ore concentrates in an aqueous alkaline cyanide solution with added hydrogen peroxide has so far not been used industrially, because it is uneconomical, i.e. the consumption of H2O2 and NaCN was unduly high. It has been found that the process can be made very economical and disadvantages of the conventional leaching technology can be avoided if the addition of the aqueous H2O2 solution is controlled via the concentration of the oxygen dissolved in the leaching solution, which contains 2 to 20 mg of O2 and preferably 7 to 13 mg of O2 per litre. Preferably, 0.5 to 5% by weight of H2O2 solutions are added under control. The process is applicable to agitation leaching and heap leaching, the H2O2 addition being controlled via measuring the O2 concentration in a measuring stream. At low consumption of H2O2 and NaCN, sometimes the gold yield is even increased and the leaching time is shortened.

Abstract: In a liquid metal cooled fast breeder nuclear reactor of the pool type, the hot and cold pools (13, 19) are separated by an intermediate plenum (24) which, under steady state conditions, encloses a volume of substantially stagnant liquid metal to form a thermal barrier between the hot and cold pools (13, 19). To avoid undesirably large temperature differentials developing for example in the event of large temperature excursions within the hot pool (13) as a result of a reactor trip, the intermediate plenum (24) is designed to permit, in such circumstances, rapid interchange of liquid metal coolant between the hot pool and the intermediate plenum, for example by way of a thermal siphon arrangement (30).

Abstract: Calibration of a vector modulator is done using a scalar detector (220) to measure the amplitude of the RF output signal, phase shifters (221, 223) to adjust the relative phases of the I and Q components of the RF carrier, and variable attentuators (225, 227) in the I and Q modulation signal input lines to adjust the relative amplitude of the modulation signals. DC signal sources provide reference signals for the I and Q modulation inputs, carrier leak compensation signals, and calibration signals for balancing the amplitude of the I and Q modulation signals. An iterative four step calibration process is followed until no change in the results is observed. The quadrature phase error is minimized by adjusting the phase shifters (221, 223). The carrier leakage is minimized by adjusting the carrier leak compensation sources (229, 231) to minimize RF output with the modulation inputs grounded (247, 247). The amplitudes of the I and Q modulation signals are balanced by adjusting the attenuators (225, 227) until the output amplitudes are equal. Finally, the quadrature calibration signal sources (235, 237) are adjusted until the output amplitudes they produce are balanced.

Abstract: An apparatus which successively converts the period defined by successive two pulses of a series of input pulses into a voltage, and in which fractional times between input pulses an clock pulses are converted, by two fractional time-to-voltage converters (103, 104) alternately with each other, into voltage signals and the voltage signals thus alternately yielded by the two converters are alternately applied, by a change-over switch (105), to a subtractor (106), wherein the later one of the two successive voltage signals is always subtracted from the earlier one of them, creating a difference signal therebetween. At the same time, the number of clock pulses present between the two input pulses corresponding to the two voltage signals is counted and the count value is converted to analog form, which is added to the difference signal, obtaining the voltage corresponding to the period between the two input pulses.

Abstract: An organic guest compound having both an electron attractive group and an electron donative group is blended with a host polymer selected from a lactone polymer and a copolymer nylon to form a solid solution. The solid solution shows good mechanical strength and processability and may be suitably formed into a nonlinear optical device. Even if the guest compound is a compound, such as p-nitroaniline, which has a large non-linearity but is by itself liable to form a centrosymmetrical crystal thus showing no SHG activity, the solid solution obtained by blending it with the host polymer can show a uniform and large SHG activity.
