ABSTRACT: Obtained by agar gel diffusion and separation with Rivanol., thefractions
of three patient sera with thrombopoietic activity and two normal sera have been,
studied with regard to their effect on the circulating thrombocyte count in mice..
According to the literature and our own exploratory data, the supernatant liquid
obtained by Rivanol separation contained only one immune electrophoretically
homogeneous A globulint transferrin, in addition to gamma globulin. The whole
serum of the patients, the A globulins as well as the Rivanol-supernatant liquids
and the majority of-the 13 globulins weremoderately or pronouncedly positive in
the mouse test, -that is, they enhanced thrombocytosis. This can be considered a
renewed indication of a relationship between the humoral regulation of erythropoicsis
and thrombocytopoiesis. Orig. art. has: 1 table. IJFRS: 34tl6l]

TITLE: The mechanism of corona discharge
PERIODICAL: Elektrotechnika, no- 5, 1961, 212 - 222
TEXT: The author presents briefly the available information on the mechanism
of corona discharge, deals with the physical characteristics of the partial
breakdown developed in the high field surrounding the anode and cathode and
explains the criteria for the field-sustained discharge. Literature des-
cribes corona discharge as a high-frequency generator in radio and TV inter-
ferences and explains its destructive effect on insulators of high-tension
cables, machines and apparatuses, but provides no answer to the question why
corona discharge can be regarded as a high-frequency generatore On the basis
of publications by L.B. Loeb (Ref, 3: "Basic Processes of Gaseous Electronics"s
University of California Press Los Angeles 1960), the author investigates the
particular characteristics of the corona discharge in air and other.gases. In
examining the corona discharge in air starting in the high field surrounding

expressing the number of photoelectron avalanches starting beyond the active
zone. The process is considered self-sustained when the first avalanche is
followed by another complete avalanche, i.e when n f=1. The practical appli-
cation of this formula is, however, extremeiy limited, since the knowledge
of the f11 f2 andA coefficients is incomplete. The pulsating corona caused
by the Trichel impulses at the caPode turns into a continuous corona by in-
creasing the potential to ov'er 10 cycles, whereby the amplitude of the im-
pulses rapidly decreases. Referring to experiments by Jones F. Llewellyn
and G.C. Williams (Ref. 41: Proc. Phys Soc. 66/A (1953) 346) and G.L.
Weissler (Ref- 38: Phys. Rev. 63 (1943~ 96), the author states that the
initial potential of a continuous corona is not constant. Cathode spots pro-

duced by maintaining a discharge for several hours explains the presence
of the time lag prior to the development of the corona discharge and the
presence of phenomena similar to hysteresis, i.e. that the initial potential
of the corona is higher than the potential when the corona ceases. Alost of
the ionization occurs as a result of secondary electrons released at the ca-
thode by positive ion bombardment. These electrons produce ionization by
moving from the strong field to the weak field, leaving a positive ion space
charge which slows down the incoming ions. According to Loeb this criterion
is valid only for a short transition period of the corona development. With
the high field at the anode in experiments on corona in gases the photo-
ionization tendency of the gas is determined by the difference between the
ionizing energy of the gas molecule and the atom, by the possible. number of
the produced metastable states and by the extent of the absorption factor.
Weissler, Loeb, Miller and Mohr describe the discharge in clear N29 H29 02qAt
and CC12F2 gases. Weissler's investigations proved that in H2 and N2 only

continuous corona discharges can occur. The characteristic curves of the
initial discharge at the internal anode in concentric cylindrical electrode
arrangement in air and.in N2 are shown in Fig. 13 and 14. The increase of
~t he current in N2proves that the avalanche photons which do not reach the
cathode in the air, bring about a considerable photo-emission in N In

considering the suitability of 02 for photo-ionization, it was proved that
the mechanism of photo-emission in 02 is similar to.that in N21- The high
absorption of the high-intensity radiation suitable for photo-ionization
causes the start of the pulsating corona in 02 directly with "pre-onset
streamers" instead of "burst pulses". Pig. 15 shows the characteristic curves
of the initial discharge between concentric cylindrical electrodes with in-
ternal anode in pure 02 according to Miller and Loeb. Argon is especially
suitable for photo-ionizationo while the CCl 2F2gas is characterized by a

strong electron affinity. In the development of initial negative discharges
in the high field surrounding the cathode the electron affinity of the gas is
the decisive factor. Due to the low electron affinity of the hydrogen and
the negative electron affinity of nitrogen and argonv Trichel impulses Can$
not develop in these gases. Experiments revealed that mixing one of these
gases with an extremely small amount~of a gas having a high electron affinity
causes the immediate appearance of Trichel impulses, thus confirming the pre-
vailing theory on the mechanism of the corona discharge. In gases which
cannot produce a negative field charge, i,e. those without Trichel impul5es,
the initial voltage is as high as the breakdown voltage, as is the case with
argon. Whether H 2 and N2 also have this property has not yet been estab-
lished. From the above experiments it became evident that in case of de the
corona appears as a source of.high-frequency interference only on small band-
width. Since in case of industrial frequency, the potential crosses the
bandwidth of the pulsating oorona 100-200 times per second, the partial break-

down of industrial voltage.is to be considered as a permanent high-frequency
interference. The widespread aosumption that corona discharge can develop
only on high-tension overhead lines when the voltage exceeds the critical
voltage is rejected by the author on the grounds that the critical voltage
of high-tension lines is the-voltage at which the conductor field intensity,
as determined by the size and arrangement of the line, reaches the dielectric
strength of the air. Breakdowns, causing interference can, however, develop
already at sub-critical voltage. There are 15 figures and 41 references:

TEXT; The article is the fourth in a series and the authors
assume that the previous articles are known to the reader. The
work done on the subject during the last two decades is re-
viewed and imperfections in the theories are jointed out. The
theories of Szpor (1942)f Bruce (1944), Loeb (1954), Schonland
"Pilot Stzamer'l- theory C1953), Honda modified "-pilot streamer"
theory (1957) and Griscom (1958) are described. The authors

and wrong assumptions. In SzDar's theory the Use of average.

standing phase is half of the advancing phase value is not jus-
tified. Bruce uses a constant which has several different values

constant corona current leaves the leader which can only flow
until equilibrium. is reached due to the radial expansion of the
leader. When calculating the radius of the leader$ Schonland
takes into account only the charge of the head of the leader
and declares the rest negligible. It is also surprising that
instead of using Hagenguth's results, Schonland uses values ob-
tained from 60 cls experiments. Griscom. calculates that the
current reaches 50 KA when the head of the leader expands. He
ignores-the fact that a current of this magnitude would result
in a substantial light effect. In practice there is no light

ther of these assumptions is correct. The intermittent progress
calculated by Honda does not agree with observations. The dia-
