I.ABSTRACT: The effect of the relative position of nitro groups in the benzene ring
of di
Initrobenzene on the kinetics of its gas phase deco:mposition.has been studied
by a =ethod e--ployiM Bourdon gages. Thoroughly evacuated 20-30 c=3 vessels con-
taining thle a&-mple were scaled amd*pjaced in a thermostat . it was found that on
'deco.-position Of o-, p-, or m-dinitrobenzene, the pressure rise rates. A reaction
itez:aarature change in the ran6e 300-350C had little effect on the course of tile p(t)
curfes which retained their S-like-shape. With decreasing tergeruture, the degree
t
of auto acceleration increased.-. The degree of autoacceltratioa was greater for
the para and meta isomers. Por all three isomers the p(t) curves fitted'vell.the

ACC NR:- -AP6032280
An increase in the wall surface area of the reaction vessel by insertion of capillsries@
into the reaction chamber increased the initial pressure rise at a rate increasing %dth
ti=e (see Fig. 1). The maximum pressure rise rate for all three isomers accured at
3C-50% deco=position, at'vhich point the degree of autoacceleration (defined as the
ratio =axi-im rate/initial rate)-vas 5-6. The total amount of gas formed on decozposi-
tion was 3.2 =ol for the ortbo isomer and about 3 mol for the meta and pars. isozzers
zol dini4trobenzene. An increase in the 'dinitrobenzene vapor concentration within the
range 50-800 = Hg increased the initial Iand the maxi-im rate substantially and camed
the @W cxw to assme a saturation character However, -the role of the wall
reEction in the absence of capill .aries.apparently was no"%,P so great as to markidly
C@IeMgp tre ho=oSeheous decomposition kinetics. Thus a 10-20-fold increase in the'
wall surface area caused only a 4-6-fold increase in the initial deco=position
rate of the ortho and par& isomers. The effect of terperature on the initial
deco=positi oir. rate of the three isomers was 'studied under conditions which virtually
exclude reaction at the wall. The closeaers of the activation energies found for
the three isomers suggested that theii 'decomposition mechanism is the same; it
apparently consists of the rupture of the C-N02 bond. The initial decomposition rate
at 350C of tae oeho isomer was 6-7 times as high as that of the meta and par&
iso rs, which decompose at almost tho same rate. The correaponding preexponential

ABSTRACT: This suggestion was awarded fourth premium in an All-
Union competition tor the economy of electric power. The
author developed and introduced a new method of making butt-
seam welds in metal 2 - 10 mm thick, working from one side and
using.- a-copp-jr The sheets to be welded are
__backing___p_iece_._______-
clamped with &- gap between'them -of -2- --_4_mM_j as-shown
The special welding machine is illustrated diagram atically,@in
Fig.2. During the process of welding, the arc burns above the'
water-cooled copper backing piece, which retains the liquid
metal and forms the back of the weld. As the machines moves
along, the clamps are removed, so that the joint is made in a
single passage through the equipment.
Economy of electric power results from the fact that the weld
is made in a single pass and not in two, as is usual. Also,
Cardl/ @here are no magnetic clamps and so no current is required to

from the use of the equipment is about 10 000 kWh.

TEXT: In this paper a method in given for-aeaauring the total-cross,
sections of the interaction between electrons or ions in a plasma by
using the properties of the plasma in the magnetic field. The method is
based on the dependence of plasma conductivity in the region of
cyclotron resonance on the cross section of particle collision in dis-
charge. The magnetic field allows a division of the total conductivity
of the plasma into components.--These components are connected with those
particles in which the resonance condition is fulfillod. The mechanism
of the phenomena is analogous to the processes in the cyclotron. The
quantitative part of this problea was studied in Refs. 2,3,4. For

The experimental results in studying the properties of the plasma of
high concentration In ioni3ed particles cannot be expressed by the
theory which considers only the pairwise collisions. The strong internal
plasma fields are connected with the macroscopic charges and currents
in dense plasmas and lead to an occurrence of new interactions among the
particles. In this connection the new interactions often play a leading
part. Such processes may be studied only in plasmas with sufficiently

connected to'the generator, the other to a date-lor with a logarithmic
amplifier. Plasma was produced by an electrodeless discharge with a
frequency of 60 megacycles. The absolute value or attenuation was deter-
mined by comparative measurements with a calibrated attenuator connected
to the antenna circuit. The results show that data on 0 and'n ca-n be
