ABSTRACT: Some consequences of the now symmetry of the Clebsch-
Gordan coefficients, discovered by Regge (Nuovo Cimento 10, 544,
19~8) are considered.:, All the for=llas of the theory of angular'

consequences of the new symmetry rules. By carrying out the Regge
1symmetry transformation, a whole series of new relations is cb-
tained between the Clibsch-Gordan 6oefficients, the Racah coeffi-
cients, and the transformation matrices. Some examples of these
new formulas are orthogonality relitions and recursion formulas for
the Clebsch-Gordan and.Racah coefficients. The Racah coefficients
that depend on projections are coniidered in particular. A graphi-
cal interpretation of the Regge symmetry is given by means of a
trilinear plot.. It is pointed ait that the Rogge symmetry rules are
of great importance not only for specific now formulas but primarily*
from the point of view of general theoretical problems, &nd its
consequences have not yet been e:Kbausted. Orig. art. has: 3 figures

ABSTRACT: A qualitative analyses is maae'of processes he decay
-optically thin hydrogen,p asma with an inverted
of highly ionized population. ~ The
following three stages in plasma are considered.: 1) stronglyionized plasma with
instantaneously cooled free electrons, wh(in the lower levels are practically un
populated; 2) considerably ionized plasma., in *hich a~ equilibrium relaxation rate
from overpopulated upper levels is establJ,shed; and 3) weakly ionized plasma. On
the basis of an equation for the rate of population change,-a general relaxation
scheme is discussed for plasma with an electron concentration between 1013 and
1016 cm73 and free electron temperatures hTe atO.1-0.5 ev. The relaxation time
T for the first stage was estimated to be 10-8_10-7 sec. The average number of

the first and second stages, and it was shdvn.-that population inv6rsion* sufficient
for laser action is maintained throughout thewhole 6econd,stage (T7 --- 10--5 sec).
It is pointed out that various effects not taken into account may become dominant-
during the third stage. These effects, suc h-as th e.increased importance of meta--~
stable-states, complicate the analysis of relaxation processes during the third
stage. However, in contrast * to the first two stagesi it is relatively easy to
maintain a stationary population inversion luring the third stage. Because of the!'

laser. The heating and cooling of free ele-Arons ins. gaseous,-discharge is also
discussed. Orig. art. has- 3 formulas and I table. (cS1

;ABSTRACT: The sudden cooling of the free electrons of a highly ionized low-temper
-ture plasma (a condition necessary foi- the attainment of laser action in such a me
!dium) is discussed. Two methods are proposed: cooling the walls of the container
;and the use of heavy particles (ions ar.d. meutral-atoms.df the plasma)*to cool the
!free electrons. The second 'method is eliscussed in detail. In utilizing heavy par-
:tic,les for cooling,two conditions muf;t be satisfied: 1) The electronic temperat ej...
Must be significantly greater than the temperature of the heavy particles (T >> T)
e
'The temperature Te must be close to the temperature of the almost totally singly
Unized gas, and the temperatures T, to the final coohng temperature of free elec-.
'trons; and 2) the specific heat of the elections must be significantly smaller than
'that of the heavy particles (Ce n

relaxation are discussed: 1) highly ionized plasma with "instanteneously" cooled elec
trons 2) substantially ionized plasma with a "stationary dowmflow" from overpopulated
levels and 3) weakly ionized plasma. The second stage is investigated quantitatively,

d3STRACT: The authors consider a plasm _Le~_ containing atoms or ions with several
discrete levels, the populations of which are much smaller than those given by the
Saha formula for a given free-electron density and temperature. They show that a
plasma jet of this kind can be used to obtain a relatively dense gas stream with un-
populated lower levels. This is done by making use of the rapid recombination that
takes place when the plasma is initially highly ionized and the temperature of the
free electrons is abruptly reduced. In this case the populations in the lower levels
cannot follow the transitions of the electrons to the upper discrete levels and the
resultant nonequilibrium situation (if the free electrons are cooled rapidly enough)
can lead to population inversion, thus making it possible: to use this gas in a laser

1confiGuration. This calls for cooling the plasma within a time 10-7 __ 10-0 sec from
5 x 103 to 103 K at a free-electron density 101" -- 3 x 1015 cm-3. In the case of an
tLrmagnetized plasma, analysis shows that, in view of the difficulty of three-
dimensional expansion into vacuum under laboratory conditions, any practical utiliza-
tion of adiabatic cooling for the purpose of producing a large amount of hydrogen with
a nonequilibrium population inversion irt the atomic levels is hardly realizable. In
the case of a maGnetized plasma, it is chown that by freezing-in a strong magnetic
field in the plasma it is possible to increase greatly the initial plasma pressure and
thus intensify the cooling accompanying the expansion into vacuum. However, the re-
quired rapid displacement of a strong magneflic field still makes such a procedure dif-
ficult. A proposed means of overcoming the difficulty is to produce a device in which
a high-velocity magnetized jet of fully ionized hydrogen is introduced into a vacuum
with a magnetic field that falls off with distance. Theoretical estimates of the
initial-plazma density required for thi:3 purpose and possible means of accomplishing
a sufficiently rapid decrease of the ma.~;netic field are discussed. The authors thank

!ABSTRACT: An investigation was made of the possibility of amplifying electromagnetic

ielements (HI, He++, Li++, etc.). In addition to investigating the relaxation of

.metals or alkali-like ions during the decay of their plasma. Numerical data are used
!in an evaluation of the amplifying properties of the decaying plasma of a chemical

ABSTRACT: Perinaphthindenone (I), like several other cyclic polynuclear
ketones, forms molecular compounds with metal halides (Refs 1,
2,4). The authors succeeded in finding that 2-bromine peri-
naphthindenone-1 (II) forms firm nuclear compounds with strong
aprotonic acids (SbC1 52 SnCl4). 2-J-perinaphthindenone-1 (III)
forms an analogous complex with tin tetrachloride. C.,H-OBr.

dioxane, but not eaaily soluble in ether and benzene; Their sol-
ubility in petroleum ether is poor. When boiled in water, the
hydrolysis destroys them completely, and they are completely

2). Perinaphthindenone hydrazone (IV) (Ref 3) also forms stable
complex compounds w:.th metal halides. They are all soluble in
pyridine and dioxane, but their solubility in alcohol is poor.
Hydrazone is regenerated with their hydrolysis. A stable com-
plex is deyeloped by a sublimate solution in absolute ether.
Salts of bivalent mercury normally oxidize hydrazones down to
diazone ethane derivatives (Ref 7). If mercury salts are su-
perfluous, nitrogen separates and organic mercury compounds
develop (Ref 8). In the experimental part the production of
molecular compounds of halogen derivatives of perinaphthinde-
none and its hydrazcne with halides of several metals are de-
scribed, as well as the production of 2-J-perinaphthindenone-1
(III), not described up to now. There are 8 references. 5 of
which are Soviet.

TITLE: The DiDole Moments and Structure of Some Derivatives of
Perinaphthindenone
PERIODICAL: Doklady Akademii nE,uk SSSR, 1959, Vol 126, 1Tr 4, PP 719 - 721
(USSR)
ABSTRACT: Perinaphthindenone (I) and benzanthrone (IV) having weak or no
characteristic ketone properties (Refs 1,2) form very solid
complex compounds irith protonic and aprotonic acids (Refs 2-4).
This auggests a considerable polarity of the C - 0 bond. The
instability of perLnaphthindene and benzanthrene is expressed
by their tendency of passing over into a stable oxidized state.
The possible existence of a perinaphthindenyl cation, produced
recently as a complex salt (Ref 5), had been presumed earlier
(Ref 6) although the attempt at producing it had failed. The
calculations of the binding energies in the perinaphthindene
system by the method of molecular orbits showed that a catiGnoid
state with a 12TE.-electron assembly is energetically advantage-
ous for this systEw. The system is aromatic if it has this as-
~ard 1/4 sembly (Ref 7). Thus, an intraionic binding charac-~er of _~'C - -0

The D4ole Mcments and Structure of Some Derivatives SCV/20-126-4-23/65
of Per-inaphthindenone
can be assumed (accc-rding to Ref 8) for the carbony! compounds
of the perinaphthind.ene series where the negative charge is
localized on the oxygen, while the positive one is distributed
over the entire carton system. An extensive analogy of the
properties of tropone (II) and perinaphthindenone permits the
reduction of its structure to that of perinaphthindenyl oxide
(Ia), using also the analogy with tropil oxide (IIa) (see Dia-
gram). For perinaphtnindenone, a considerable dipole moment
(in the magnitude of 4D) can be expected, all the more so as
tropone has a moment between 4.17 and 4.30 D (Ref 9). To clar-
ify this problem, the authors measured the dipole moments of
perinaphthindenone and some of its derivatives. Table I pre-
sents the results showing that the dipole moment in dioxane is
reduced by 0.72 D by the introduction of bromine into the
nucleus of perinaphtlAndenone, and in benzanthrone by 1.19 D.
The introduction of 6. bi--nzonal nucleus reduces it by 0.5-0.06 D.
On the other hand, the dipole moment increases by the intro-
duction of an oxy group into Position 7 of Derinaphthindenone
M. An Intramolecular cycle with a hydrogen bond is formed.

JABSTRACT: This Author Certificate presents a device for differential transforming
lof aerial photographs. The device is usel in conjunction with a photogrammetic
device for processing aerial photographs. It contaihs an inversor which acts an
l
ithe basic law of optics, and a photograph support and screen which may be posi-
-; tioned relative to one another in three mitually perpendicular planes. Accuracy in
,scaling is facilitated by the inversor which features a reduction device for
~control of the coefficient of aerophoto transformation with allowance made for
'focal distance. T.ds distance corres .ponds to the tran form coordinates of the
iourrent point of aerophoto slope on the h:)rizontal aerial photograph. The inversorl

is made in the form of direotional-controlled rods and connecting links.attached to
each rod, thus allowing rotation about the X-X axis and intersection of the
directional at a point on the X-X axis. Electrical control of the coefficient of
transformation is maintained by an eleotromoter circuit controlling the variation
ol' distance from the objective to the pho-bo and from the objective to the screen.
This is an electrical bridge circuit for processing data coming from.the Photogram-i
metric device.

TITLE: Investigation of Electrical E-quipment of Type N8 Electric Locomotive
PERIODICAL: Sb. Leningr. in-ta inzh. zh.-d. transp. , 1957, Nr 155, pp 29-44
ABSTRACT: To Introduce final corrections, the scheme of a type N8 electric
locomotive had been tested under various conditions before serial
manufacturing of the 10COMOUVE was started. Under regenerative braki.--)g
conditior-s. the current reached 2, 000 amr)- On the section where the sub -
staticnns had no inverter equipment, the contact-wire voltage reached 4, ZOO v,
with NB-406 traction motors operating normally. Investigation of the trar-gients
accompanying the transition to veries connection showed that sometimes, u-nder
regenerative conditions, the residual E~" of traction motors is so combined
with the contact -wir e voltage thit voltages up to 5, 100 -6, 000 v appear on the
mctor brushes. This caused flashovers from energized motor parts and

Investigation of Electrical Equipment of Type N8 Electric Locomotive
equ-ipment to ground. To elimin4_te such overvoltages, it was suggested t1lar.
the motors next to ground be shcrt-circuited. To eliminate burning of ccatactS
of the braking switch under tra--:iient canditions, it was recommended that t,~'-o
con-tactors be used for breaking the traction-motor field circuit when
regeneration is cut off. Tests of a new laminated-core D-4 relay showed that
-~t provides a satisfactory differEr-tial protection of the power circuit. Buffer
protection, under traction conditions, is realized by introduc-ing starting
resistors; its operating time is '). 1-0. 2 sec, the motor current beL--g :-educed
to one-third of its value. Investigation of the functioning of the protective
svstem under regenerative cond:.tions permitted setting a course for solving
this important problem. Forced ventilation is recommended for improving the
operating conditions of "fekhral' resistors. Detailed investigations of ail
exchange within the locomotive bodv Dermitted providing sor-rie recom_rnenda*_-'o!i9
on how to imDrove the ventilati-no, svstem. Bibliography: 3 items.

ABSTRACT: The deformations at the.site of the greatest reduction in area of Ti (VT1)
and Ti-alloy (0T4, VT6, VT14) test specimens in two mutually perpendicular directions
were compared in order to indirectly obtain information.on the anisotropy of mechani-
cal properties. An IM-12A tensile testing machine was employed and the specimens
were previously subjected to various types of thermomechanical treatment (rolling at
500 to 1100*C through every 100*C with reductidn of area amounting to 20, 40 and 60Z
and with subsequent cooling in water, ai:,- and under asbestos). The criterion used to
estimate deformation in the neck in two inutually perpendicular directions was the

ABSTRACT: On account of the e::amination made here, the following is
stated: 1) A compar:.son of different methods of determining
the minimum length of the frontal outside strip end in rolling
(Ref 3) shows that the easiest and sufficiently accurate method
is the one basing or. the measurement of the full pressure of
the metal on the rolls and the recording on an oscillograph
(Ref 4). 2) The increase of the full pressure after the filling
of the roller opening may be explained by the supporting effect
of the frontal outside strip end, leading to an increase of
the metal deformaticn resistance. In rolling stainless steel,
the supporting effect of the outside end is always greater
than in rolling titanium. 3) The speed of the frontal strip
end after -rip7.ing lecomes constant after the discharge of the
Card 1/3 frontal end of a certain length (corresponding to the minimum

length of the outs:'de end) out of the rollers. 4) At the
moment of filling -:he roller opening with metal, the
critical angle is i3maller than the critical angle of the
stabilized process stage. The latter angle is determined by the
lead. The critical angle becomes greater during the initial
process and the development of the lead zone at the expense
of the utilization of the reserve frictional forces. It
becomes the greate:r, the more the frictional coefficient of
the rolling metal Lncreases. 5) The minimum length of the
frontal outside strip end may be determined by measuring
the width of strip throughout its length (Ref 3). In this
case, the frontal outside strip end may have either a
fan-shaped or a na.rrowing form. 6) Well comparable results
were obtained by all methods for determining the minimum
length of the frontal outside strip end in rolling (by
the general pressu:7e, by the speed of the frontal end and
by the spreading). '!his confirms the correctness of theoretical
ideas as to the importance of the outside parts of the
deformed body ("thoory of rigid ends") (between quotation

diameter rolls fitted with ball bearings was used to roll
specimens 10 mm thick, 15 mm vride and 150 mm long. Total rolling~
pressure was measured with carbon load cells in the screw-down

output being amplified electronically and'recorded, together with
total rolling pressure by means of an oscillograph, Specimens
were preheated to 800-,1200"C to give uniform temperature

angle ~p, i.e- the angle between the radius through the point of
application of the total metal pressure on the rolls (acting in the
direction of the vertical axis) and the.'a'xial line, varies within
the range 2- 3 for both steel and alloy.,first falling and then
rising with increasing reduction, The authors note the
importance of this parameter, Spread was measured by finding the
change in distance between two points on the side of the specimen
produced in rolling, The lateral spread is plotted as a functian

at 900- 9500C. Spread a's a function of relative reduction is
shown for the steel and the alloy in Fig-3, left and right-hand
graphs respectively, at 800, 1000 and 12000C. The work has shown
that foir VT5 alloy the specific pressure in the beta-phase region
is considerably less than in'the alpha-phase region, the
transformation.leading to an abrupt change. The spread mechanism
in rolling titanium is mpinly througli barrel formation, whi-le with
steel it is mainly through slip along the c *ontact surface. The
dependence of the index of spread on temperature is also affected
by the allotropic transformation, the index being lower for alpha
than for beta titanium: -the narrower the temperature interval of
the transformation the sharper the ch~ange. There are 3 figures,

TEXT: The influence on the friction coefficient of scale or
an oxide film layer on the surface of a metal being rolled has been
the subject of numerous paperfi. However, no direct comparison was
made of the ordinary process of rolling aluminium in air and in
vacuum. Such a r-mparative study will permit direct elucidation
of the influence of oxide films on the conditions of rolling. The
authors investigated the power consumption, the speed and deforma-
tion conditions and the friction coefficient during hot rolling of
aluminium in vacuum and in air. The rolling was on TsNIIChermet

Rolling was at 4000C with reductions of 20 to 70% per pass. The
diameter of the rolls was 85 mm, the rolling speed 6.5 m/min. The
rolls were of steel W )(-IT (ShKh-15) (hardness 55 Rc ) and had a

considerably lower than for rolling in air, i~;-hilst for nickel and

again confirms the dependenco of these quantities on the chemical

the greatest difference (by a factor of about 1.4) was observed
for smaller reductions;
2. it was confirmed that th'e- friction coefficient during rolling

speed of rolling was 6.5 m/min.. The rolls had a ground surface
with a hardness of 55 RC. The rolling parameters, 1.e. the total
pressure, the torque., the speed of the rolled strip and the
circumferentlal speed of the rolls were recorded by means of an
8-loop oscillograph. Fig.3 shows the dependence of the fric ion
.oafficient, VO' and of the specific friction force T . kg/mm
on
the rolling temperature, OC. Fig.4 shows the dependensce of the
friction coefficient fl and of the forward slip S h on the rolling
temperature, OC, Fig-5 shows the dependence of the specific
pressure, kg/mm2, on the rolling temperature, *C. Fig.6 gives
the dependence cf the specific pressure, kg/mm 2, and the friction
zoefficient fl on the reduction, %. In all these graphs the
continuous line curves apply to roll--ng in air and the dashed line
curves to rolling in vacuum. In thE paper the auth:)rs apply
three differing friction coefficients., one f"' determined

V. i3ayukov and the third, V, determined from the value of the
forward slip. The following conclusions are arrived at-.
1. In all cases of rolling in air the curve expressing the
dapendence of the friction coefficient on the temperature has a
ccnvex-shaped section with a maximum in the temperature range
i050-11500C~ If titanium is rolled in air at *800-11000C, a dense
layer of titanium dioxide scale forms which leads to an increase
"n s.:.iding friction coefficient and spreading. At rolling
temperatures above 11000C, a derase layer of scale of a fine grain
iitructure forms which peels off easily from the base metal and
leads to a reduction of the friction coefficient, the friction
coefficients fj and f" are similar and their values are very
n,E!ar to each other. When rolling was performed in vacuum, the
triction coefficient was considerabiv lower and showed a tendency
7e~ increase with increasing rolling temperature. Th-i-;z is
~~Liributed to a drop in the specific pressure with a minimum
-affe:t of 3ther factors.,
Changes in the specific pressure p and the specific friction
"3rce "5 were similar during rolling in vacuum and in air. The

values p and r , and consequently also the torque- are affected
by the sudden a ?o P transformations and this explains the sharp
drop in the friction coefficient, forward slip and the slight
'-ncrease In spreading in the temperature range 850-9500C.
5~ With increas.ing reduction an increase is observed in the
specific pressure and a decrease in the friction coefficient.
4, The exper--ments revealed considerable qualitative and quantita-
z;,Ye differences in the force, velocity and geometrical factors
pertaining to rolling titanium in vacuum and in air.
Experzments carried out earlier by some of the authors (Ref.14:
Sial', 1959, No.10, 929-931) yielded differing ri~,sults. namely,
the coefficient of friction and the geometrical and force
conditions depending on it were considerably higher in vacuum
than in air in the case of rolling pure iron with a carbon content
of 0.,01%. This clearly indicates that the investigated quantities
depend on the chemical composition of the rolled netal. There
