The decampu potentials of pure mc.Iten silvel
halides (AgCl, AgBr, and AgI) are measured
employing a modified method of taking current-
voltage curves using various sized cathodes
and the same anode. Two decompa poteatials,
21M
for each molten salt, caused by 2 different
cathode processes, are established. The pres-
ence of a 2d potential in such simple system
cannot be ascribed either to the decompa of
the solvent or to gradiial dissocn and therefore
can only be attributei to the decompa of complex
ions.

The decomyn potent ials of acetone 6olne of lithium
chloride in the concn range of 0.004 to 3.89% Lici
at various cathode currents are detd. The pres-
ence of 2 decompn potentials in all of the aolne
investigated was established: the 1st (lov)
potential corresponds to the deposition of dense
metal, and the 2d (high) corresponds to formtion
of a porous, black deposit. It is shown that
the 2d potential is not connected vith deccapn
of the solvent. From changes in the 2d poten-
tial depending on the concn, temp and adda of
vater, it follovs that this potential results
from decompn at the cathode of complex cati
of the type:

The decamp potentials of lithium chloride in iso-

owthod. of taking curreat-voltage curves vhich
allows the cathode processes to be made apparent

1A established. The lat (law) potential is the
222T9
usual one for lithium, corresponding to the depo-
sition of the dense metal; the 2d (medium) corre-
sponds to a black, porous cathode deposit, and
the 3d (high) is t ied in with the decompa of com-
plex cations in a -nn r similar to the 2d. The
obtained results and conclusions agree well vith
other physicochemical properties of the system
studied.

stud-led and the presence of 3 decompa potentials *s-
tablisbed. The Ist, ordinary one corresponds to the
deposition of dense metal and the 2 higher on" to
a black, porous cathode deposit. It is shown that
in the system LiCl - C; there exists a complex
equil. betveca simple lfytiun ions and 2 types of
cor.n1ex cations with different levels of solvation,
the compa of which changes with different conens
and temps. 1z connection vith the good complex
forming properites of pyridine as a solvent, there
&rise, at definite solvent concus, favorable condi-
tions for sharply delimiting zones of the denso and
the porous cathode deposits. These zones then #bow
great difference in values between the lower and the
higher deconqpn potential . The concus corresponding
to the niost favorable conditions for getting dense,
light gray lithlus deposits are given.

A large amount of reports dedicated to this problem at the All-Union
Electrochemical Conferences (in Ivanovo in '1945, in Kiev in 1948)
shows the need in theoretical works. The rather extensive patent
literature indicates the increasing demand of industries for electro-
lytic powders. The monograph is provided with tables and diagrams.

Abstract: In an effort to determine the possible relationship between the
quality of electroplating and the current density (i) used in its
deposition, the preservation of the potential of Cd deposited on Pt,
Ag, Cu, and Fe from a 0.1 N solution of CdSO4 has been investigated
as a function of the i used in the depooition. The method consisted
in establishing the time required dor the solution of a given weight
of Cd, which was determined from the jump in the potential of the
electrode. It is shown that the higher the i used in the deposition
of a layer of Cd on a foreign surface, the longer the time during which

Abstracts the Cd potential is maintained,for the same amount of deposit. This,
in the opinion of the authors, is due to the greater compactness of
the deposited metal. The opinion is expressed that the new method
can be developed and applied to the investigation of electrode and
corrosion processes by studying the time during which the ]potential
of the cover metal is maintained.

ABSTRACTs The determination of diffusion coefficients according to the
hitherto used methods, some of which are mentioned, still
leads to considerable errors because the temperature can be
kept sufficiently constant only with difficulties. For this
reason the authors used fox the determination according to
Skoboto and Kavetskiy (Hof 11) the current impulse which
occurs in sw1tching on the electrolysis. The eloctrolytes were
solutions of WO , ZrSO , Cd.90 and AgNO of dif f eren't concentration

(Table). The current density and the period until the
occurrence of the first cathode precipitation wire measured.
A measuring device was developed which is shown by a scheme

voiic(~ntration was K4P,,O70.05 m and Pb(NO 3)2 0-03 m- It can be
ueun from these data that the amperage decreases rapidly if a

a certain concentration (Fig 4) 'the minimum and miaximum on the

by the formation of a continuous adsorption film of peptone.

PERIODICAL: Ukrainakly khimicheskiy zhurnal, 11960, Vo;. 26, No. 1,
pp~ 36-40
TEXT: The nuthors describe a new method of studying free diffusion in
very thin, electrode-near layers. It is based on a sudden impoverishmen t
of the electrolyte on the cathode during short-termed electro'Ayjis at
high amperage, and on observing the balance of concentration when the
currc-nt is switched off. Fig. 1 shows the circuit of the measuring
apparatus. The time relay 1 has a contact pair clojed in thQ normal atat-,
ani one wh,,ch is open. The closed contact pair slc3es the d.c. circuit tc
which the electrolyzer 7 is connected. The contact pair of relay 2, WhicY
I,-; cp,~n in the n,~rmal state, Is connected In p,trallel w!th the formor
contact pair. The winding of this relay Is conne7ted w1th 'hrb contact pair
of relay 1, which is open in the normal :3tat~,... The seconds counter 4 is

connected with the ciroult of the second contact pair of relay 2 and of
the tube relay 3. The following process is conducted: Ths:. time relay 1 is
adjusted for a period within which a black metal precipit,~'- 1-cmes
visible on the cathode and the concentration in thr~ ele-,trcd-3-near layer
practically vanishes. When the time has elapsed, r9lay 1 switches off
electrolyzer 7. At the same time, relay 2 is sw1tch,:d on, which again
switches off after a given time, and switches on thp r-lectrolyzer and the
seconds counter. After this proceaa, which -;rrriapords to the formati.;r. of
a precipitate on the, cathode., the terminal, potential of the eleotrolyzer
rises, and the ccntacti of the vcltmeter 6 are .LD3el, whereby the tul,~-

The followinC wan stated: With riving concentration of the electrolyte,
more substance diffuses, i.e., the rate of concentration balance is
directly proportional to the initial concentration. In dilute solutions,
the, concentration is balanced within 30-35 seconds. Experiments with
equimo.lar solutions of various salts shu-.-.ed that the diffusion rate
depends on the type of anion (Fic. 4). D. N. Gritsan is mentioned. There

TEXT: The authors have studied the usability of nickel-pyrophosphate
baths which in comparison to cyanide baths have the advantages of being
harmle3s and sufficiently stable. They studied the influence of component
.1oncentration, temperature and additivea on the quality of the niokel
deposit. The following additives were tested: H 2s0 41 HC1, KC1, formalin,
rhenol, peptone, Seignette salt and urea. The tests were carried out in
a sinrle bath or in several baths connected in series (6 x 2.5 x 9 cm,
100 ml volume) with plate-shaped nickel- and copper anodes. The back part
of th-? anodes was isolated by a layer of paraffin or varnish. The electrcde
potentials were measured by means of a nnTB-l (PPTV-1) potentiometer
against a saturated calomel electrode as reference and reduced to a normal
nydrogen electrode. The electrolyte composition was no chosen as to give
clear ani stable solutions. This was the cane with solutions consisting

also found that the diffusibility of pyrophouphate electrolytes (according

electrolytes. In service of pyrophosphato baths consisting only of Niso 4

TITLE: Physical conditio-4irf-or an efficient detection of flaws in high-voltage
pulsed capacitors ~!!~
SOURCE: AN UzSSR. Izvestiys. Seriya tekhnicheskikh nauk, no. 4, 1965, 11-18
TOPIC TAGS: capacitor, dielectric breakdown, dielectric insulation, flaw detection
ABSTRACT! The physical processes accompanying the rise of partial discharges and
local defects in the insulation of high-voltage pulsed capacitors used as energy
reservoirs for high pulsed currents are discussed. It is shown that in high-vottage
pulsed capacitors with a large number of parallel- or series-connected sections there
exists a pre-breakdown state caused by the development of ionization processes due
to the presence of such defects as cracks, various inhomogeneities, and air and
other inclusions in insulation, which ultimataly lead to the dielectric breakdown
of the capacitor. The breakdown of one section doe not immediately lead to the
breakdown of the entire capacitor. The flaw finder y be adjusted to signaling the
appearance of the first section with Sre&kdown. tRe resistance of the breakdown
channel of the defective section is & function of the magnitude of current flowing
through this chanel. The "metallic zero" -resistance of the breakdown channel of the

defective section may be e1 iminated by meana of a specified number of discharges of
the capacitor battery, which Includes the capacitor with the defective section, at
up to 50% of its rated voltage (with respect to its rated load resistance). As tile
pulsed discharge current passes through the defective section, a shock wave &rise-#
in the breakdown channel and is recorded by appropriate instruments. Orig. art. has:

Leningrad, Gidrometeoizdat, 1957, PP 185 - 188
ABSTRACT,, Not only the number of particles within the volume unit, but
also their dimension distribution can be determined by the
ultramicrosooplo floW investigation method, For *.his purpose,
an optical discriminator (photometric wedge), making it possible
to obtain the partiole-brightness distr1bution, was mounted into
the 'target illuminating device of an ultramicroscope. A new
wedge-graduation method is described; the graduation curves of
the dependence of particle dimensions on the wedge position can
be obtained quickly, when applying the method mentioned. The
authors report on the flow method applied to the study of' the
Card 1/2 atmospheric condensation nuclei. For this purpose, a simple

moistening chamber and a cooling channel, in which vapor condensation on
the condensation nuclei proceeds. The condensation nuclei, enlarged in
this way, are carried away by the air current, arrive at the cell of '11ia.4

tion conditions of the device were determized experimentally, By the Ultra-
microscopic flow method, the automation of registering aerosol part.L~les or
