POLAND / Physical Chemistry. Electrochemistry. B Abs Jour: Ref Zhur-Khimiya, No 18, 1958j 60345. Abstract: the cylindrical Cu anode was studied, and the equi- valent electrical conductivity ( A) and the vis- cosity of the solution (q ) were determined as well. It is shown that the EP takes place at E from +0.82 to +1.6 v (stand. H electrode). i(lim) increases linearly with m at the rise of m from 60 to 670 revolutions per min. At m = 400 rev. per min,, the experimental data are expressed by by the equation 1/4(JJM) = A + Bc. It was found that r ,k and I/A depend linearly on c, and that i(lim)h, = const. and i(lim)X = const., if c was changing. It is assumed that the limiting stage of the EP is the diffusion of the phosphoric acid radical to the anode surface, and that the conver- sion of Cu into Cu2+ proceeds through an inter- mediate formation of an oxide phase.

An increase in the quantity of Fe dissolved in the electrolyte does not change the form of PC. In 20 and 40 n- of H;P04, the electropolishing of Fe and steel is p asible in conditions which conform to the rising segment of PC in the area of 02 isolation. It in proposed that the passivity is specified by reactions of the type M+20H----) --MO+H20+2e.

Abstract: A case of corrosion (c) is described involving storage of the stainless steel parts of a steam generator made of ST. 2H13 (0.16-0.24% c, 12-16% Cr) wrapped with well oiled and graphited asbestos tape; Before the storage the involved parts were subjected to a hydraulic (or steam-water) test at a temperature of 3600. These tests were conducted in a chamber for 72 hours, at 800, and at high humidity conditions.

For the determination of the effects of grease decomposition products on C, water was ana- lyzed after the treatment of greased tape in an autoclave. It was established that products of grease decomposition do not contain corrosive com- pounds (such as chlorides and sulfates), hence, their presence does not affect the rate of C. The basic reason of the existence of C is the contact between the chrome steel and graphitej Moreover, the increased rate of steel C is proportional to Card 2/3 ROM POLAND / Chemical Technology.

The number and degree of evidence of positive reactions to brucellosis in the vaccinated persons are mainly determined by the massiveness of the foci of infection in I which they work. R is very doubtful that repeated vaccination can cause hypersensitization in people, but In all proixibility it can intensify, in vaccinated persons, a state of hypersenst- tization which arises when they are repeatedly infected when working in a focus of infection. The authors use the data obtained as grounds to conclude that persons with positive immuno- logical reactions to brucelloste should be excluded from vaccination. Orig. art. has: 2 ZargLIMAN3 B.

This device differentiates a sawtooth voltage for'a sub-equent measurement of that differenti-: .ated pulse section, which corresponds to the working section of the savtooth voltage, as explained by D.I. Atayev (Ref.1). The block diagram of this device is shown in fig.3. The differentiat- ed pulse enters an amplifier composed of one section of a 6N6P tube, proceeds -. to the phase inverter with a 6P9 tube, to the li- miter-am.Plifier with 6Kh6 and the other section of the 6NOP tubeg and finally to the oscilloscope 251. A model of this device was used for measuring with a,10 per cent accuracy a 0.06 per cent nonlinearity in sawtooth voltages with an amplitude of 100 volts Card 1/2 and a duration of 100 microseconds. With other parameters of the SOV/115-59-7-19/33 Measuring the Nonlinearity of a Sawtooth Voltage sawtooth voltage, the nonlinearity measuring ranges will change. accordingly.

This device produces a pre-determined number of pulses of both polarities of different length, amplitude and pulse frequency. The number-of pulses to be.transmitted,is controlled by the operator. This device, called ODChI (obraz- tsovyy datchik chisla impullsov) is a photo-elec- tronic device, consisting of an optical-mechanical unit- with a,rotating_disk, and electronic control unit and a pulse sequence transmitter unit. The optical-mechanical unit consists of a rotating disk of 250.mm diameter having 300 rectangular openings near its rim and one close to its center. The light falling on two photoelements is interrupted by the rotating disk. The photoelements work on two chan- nels. During one rotation of the disk, a series of pulses is created in the first channel by the open- Card 2/4 ings near the rim, and one pulse by the opening near Rum SOY/115-59-13-19/29 'A Fulse,Number Test TransmitteD for Checking Counter Units of Discrete Action Measuring Instruments the cent~x of the disk in the second channel. The electric motor which drives the disk develops a maximum of 6,000 rpm which corresponds to 309000 pulses per second. The length of the pulses car- be varied from 1 to 30 microseconds with anampli- tude of up to 80 v. It is difficult to obtain a higher frequency with this method. The electronic control unit is also divided into two channels. The second channel serves for forming rare pulses and contains a level trigger for converting the bell- shaped pulses from the photo-stages into rectangular ones, which are delayed by a blocking generator for exciting the next stage. Further there are a k- pp relay and a trigger controlling the gate circuit. The gate circuit passes or blocks the passage of the working signal in dependence on the control signal.

The time interval t between the two pulses is proportional to the input voltage U x i.es t AIUx The first of these two pulses opens a gat-e circuit 3 by means of the circuit 2 while the second pulse closes the ~pte (or the switch).

The filter-amplifier of the equipment indicates the DC component of this pulse train. The mean value of the voltage at the output of the digital voltmeter 5 is thus given by: aIA U Vy T where a is a constant coefficient and T is the repetition period of the pulses. It is seen from Eqo (1) that the error in the output voltage of the multiplier is dependent on the errors of the-converter 1 coefficient a andperiod T . The error of T can be made negligible by employing a tuning-fork or quartz oscillator as the frequency standard for the converter. The actual oscillator employed by the author was stabilized by a tuning fork. The converter is illustrated diagrammatically in Fig. 2.

In the present work, the author *considers the relationship between the fluctua- tions of the slope of the sawtooth volt 'age, the amplitude, and the operation threshold an one hand and the circuit parameters and the noises of the convex-ter on the other. In the analyzed converter, a diode-regenerating zero-element with positive feedback wai used. It was found that the absolute value of the mean square deviation of the opera- tion threshold a t does not depend on the condensor voltage. Thus, it follows that Ot is a noise component of the zero-level of the zero-element. The second noise componev 1/2 UDC: 621.374.088
