Abstract: TITLE            AIR SCRUBBER OPERATING METHOD            ABSTRACT          An air scrubber is operated to reduce the rate of escape of scrubbing-liquid particles from the scrubber along with the clean-air output.  The scrubbing liquid is broken into finely divided particles which are mixed with the air and then concentrated together in a recapture region.  The particles are preferably divided more finely than otherwise possible by adding a surface-active agent to the liquid, and electric field effects are created to produce electric image attraction between the concentrated particles.  This is done either by producing static electric charges on the particles or by electrically charging an element in the region of the concentrated particles.  The concentrated particles are made substantially more likely to reagglomerate and become more readily re-captured by adding a surface-active agent reducing liquid surface tension or an electrolyte increasing the conductivity of the liquid, or both.  A preferred electrolyte for water as a scrubbing liquid is calcium chloride or sodium chloride.  The electrolyte alone, the surfactant alone, and the combination of elec-trolyte and surfactant each effects substantially more liquid particle agglomeration and much less escape of liquid particles and entrained pollutants in the output from the scrubber.

Abstract: SYSTEM FOR MAINTAINING EXCITATION OF   AN ALTERNATING CURRENT GENERATOR DURING EXCESSIVE OUTPUT CURRENT CONDITIONS            Abstract of the Disclosure In a generating system having a shunt-type reg-ulator for exciting the field of a generator during nor-mal operating conditions, circuitry is provided for sup-plying voltage to a field winding to maintain excitation of the generator during excessive output current condi-tions.  This circuitry senses the low voltage indicative of a fault or overload condition and in response boosts the field of the field winding during such an excessive output current condition an amount sufficient to main-tain generator excitation during that particular condi-tion.  It does this by impressing a  voltage, supple-mental to that supplied by the regulator, upon the field winding during the condition.  As a result the excita-tion of the generator is maintained.

Abstract: Abstract of the Disclosure An optical isolator of reduced insertion loss and fabrication cost which comprises a nonreciprocal optically active element, such as a Faraday rotator, for 45° rotation of polarization, a pair of lenses arranged on the opposite sides of the optically active element and a pair of birefringent crystal plates on the outer sides of the respective lenses having their "principal planes" displaced 45° from each other. The light beam passing through the isolator is most constricted at its opposite ends where the birefringent crystal plates are arranged and this minimizes the amount of offset required between any reflected light and the incident light at the entrance end of the isolator to prevent the reflected light from returning to the light source such as a semiconductor laser, thus enabling substantial reduction in thickness of the birefringent crystal plates. The use of two lens elements is effective to reduce the coupling loss of the isolator.

Abstract: ABSTRACT:        A notch filter   is provided with an ancillary circuit including a non-inverting amplifier and a coupling which enables the filter to form part of an oscillatory loop of which the frequency of oscillation corresponds to the frequency of maximum rejection by the notch filter.   Measurement of that frequency facilitates the tuning of the notch filter, which includes capacitors constituted by varactor diodes.          The gain of the ancillary circuit may be adjusted to change its mode of operation from oscillation to that of a tuned amplifier so that a sweep of the centre frequency of the notch filter through a range of interest facilitates a search for an unknown interfering frequency and the simultaneous tuning of the notch filter to reject that interference.

Abstract: ABSTRACT   In an igniter for spinning shells, a mobile rotor 20, carrying the detonator 23, is unlocked by two locking means acting independently of each other.  One of the locking means has a drive in the form of balls 6, 9 which, after being released by the first locking means, bring the actuating device 11, 13, 16 into its operative position.  The other locking means is in the form of an inertia-pin 18 engaging in a recess in the rotor.  With these igniters, spinning shells cannot be ignited before they leave the muzzle or before a muzzle-leaving period has elapsed.  The two safety systems locking the rotor engage therein in such a manner that the latter cannot leave its safe position as a result of impact or vibration.  Instead, under the influence of rotation, the balls (6, 9) lift the needle-carrier (16) from the rotor against the force of a spring (13) and, on the other hand, when the shell is fired, inertia causes the inertia-pin (18) to release the rotor from its position of rest, after which ignition can follow as a result of impact or when the rotational velocity of the shell decreases.

Abstract: ABSTRACT OF THE DISCLOSURE :           The present invention relates to a continuous Process of Smelting Metallic Lead Directly From Lead- and Sulfur-containing Materials.  A slag phase and lead phase are conducted in a countercurrent to each other in an elongated horizontal reactor, in which a gas atmosphere is conducted in a countercurrent to the slag phase.  To maintain the molten bath at a constant temperature and to permit an operation at the lowest possible temperatures whereas an undercooling of the melt is prevented, the temperature of the molten bath in the reducing zone is maintained constant by a controlled supply of additional heat, the temperature of the molten bath in the oxidizing zone is maintained constant by a control of the ratio of oxidizable sulfur to oxygen in such a manner that in case of a temperature rise the ratio of sulfur to oxygen is increased in order to decrease the lead oxide content of the slag and in case of a temperature drop of the ratio of sulfur to oxygen is decreased in order to increase the lead oxide content of the slag and the increase and decrease of the ratio of sulfur to oxygen are controlled with an allowance in advance for the fact that the heat content of the gases entering the oxidizing zone from the reducing zone is changed with the lead oxide content of the slag.
