TARI OF CONrENTS:
Samarin, A. M. Problem of Using Vacuum in Metallurg:r 3
The author begins by discussing the important advwitages of
the Tacuum-welting of steel. Chief among these art (1)
assurance of a minimum content of oxygen, nitrogen, and
hydrogen, as vell. as of nonmetallic inclusions; (2) the possi-
bility of deoxidizing the steel by carbon alone,vith consequent
absence of oxide inclueiona; (3) protection against reoxidation
during teeming. Turning to problems, Saomrin states, first of
&U, that Soviet induction vacuum-malting furnaces are of
unsatisfactory design, and that Soviet metallurgiel;s should
carefully study foreign furnaces of more advanced design.
Another important task is the investigation of retractnry
materials suitable for the construction of vacuum-furnace
crucibles. Further, the problem of controlling the temperature
and composition of molten metal during the malting process
must be solved. Though there has been considerable expansion
of vacuum melting in the USSR in recent years, Smarin states
Card 2/14

Use of Vacuum in Metallurgy (Cont.) 135
that annual outputs of tens or hundreds of thousands of tons of va.--uum-
melted steel cannot be expected as yet because of the cost and compiex4-y
of new equipment and the very high consumption of electric power. A
miggested partial solution is to subject ordinary liquid steel (not
---ium-melted) to vacuum treatment to eliminate the gases. For this pur-
le, the steel may be treated either In the ladle or during the pouring
the Ingots. These procedures have been industrially tested vith gorvi
--qiilts. There are 9 references of vh1ch 7 are Soviet, I English,, and

A.M. Vacuum Melting of Transformer Steel
~-he withors have established the follow-Ing facts& 1. In vacuum-
,nplted transformer steel, pover losses are 15-20 percent lover than
In ordinary transformer steel, and magnetic permeability and plastic-
11-y are greater. 2. Use of the vacuum technique makes it possible
to organize the production of cold-rolled transformer steel vith a
tilgh silicon content. 3. The electromagnetic properties of vacuum-
melted transformer steel are superior because of a law content of
h9xvLful Impurities like carbon, oxygen, and sulfur. 4. The vacuum
method increases the deoxidizing capneity of earbon by about 100

Belyakov, R.S. Effect of the Melting Method on the Prrypertles of
Stainless Steel
Author's conclusions: 1. Chrome-nJckel stai nless steel which is
not subject to intergrartular corrosion can be made In an InductiDn
vacuum-melting furnace with a residual pressure of up te) '10 mm. of
mercury, without the addition of stabilizing elements and without
the lose of such chrome from the stainless-steel scrap additions
in the charge. 2. Steel with a carbon content not exceed.Ing 0.02
percent can be mad by keeping the molten metal under vacuum for
30-40 minutes. 3. Vacuum-melted chrome-nlckel stainless steel is
more resistant to attack by boiling nitric anid (thun non-vacuum-
melted] because of low carbon content and total absence of
titanium. There are 1-1 Soviet references.

Kamenetskaya, D.S. 3ome Theoretical Questiona of Vwnaum Metallurgy
Author's conclusions-. 1. Tn the vacuum melting of metals and
alloys, there must exist over the metal a pressure r;omvhat exceeding
the vapor pressure of the metal at the triple point. At a lower
prossure, the metal volatilizes. When the vapor pressure of the
metal is less than 0.01 mm. of mercury, the [required] pressure is
created by the vapors themselves; at higher vapor pressures-0.1 sm.
and above-it is necessary to increase the external pressure,e.g.,
by the use of an inert gas. 2. The degree of vacuum, or purity of
gas, necessary for degasifying the metal and for minimum reaction
with the gases remaining in the furnace depends on the vapor pressure
of the metal: the lover the vapor pressure, the higher the vacuum,
or the purer the inert gas, aust be. The vapors over the metal,
provided their pressure is high enough (0.01 mm. and above) form a
protective envelope, which plays an Important part In the melting of
the metal if the vapors react with the gw . 3. In selecting materials
for crucibles, protective covers for thermocouples, stoppers, graphite
parts, etc., it is necessary to take into consideration the vapor and
diseDclistion pressures of these materials, and also their possible
reactions vith the metal and with each other, accompanied by the liber-
ation of volatile matter. 4. Tt is most advisable to conduct the

ABSTRACT: The influence of residual stresses in the stocK of steal I.Kni'/IN2 on the
warping of turbine blades produced from the latter materiaiwas inve-s-t-iga-L-ed at
TsNI1TMASH. The effect of taree dilforent treatments of the stock on tno rosioual
stress was studiedt a) quencl-Ling from 1030C in clamp and annealing at 550G, followed
by cooling in'air; b) free quonching from 1020C, annealing at 5700 in clamp, followed
by cooling in air, and c) quenching from 1020C in clamp and annoaiing at, 560c; in claqR,
followed by cooling in furnace. The experimental results are shown graphically (see

is Rayleigh. which corresponds to physical models of
single-ray and multi-ray channels where qhe amplitudes
and delays are independent random quantities. Various
types of optimization are then considered.
Optimization for minimum mean-square deviation of
transmitted message from that received with fixed
predistortion and corrector. Linear coding of the
0essages is assumed. The linear coding network is
termed redistorter. The output signal is decoded into
the output message by a linear circuit termed corrector.
For a given mean output signal power, the problem is to
find the predistorter and corrector which minimize the
mean-square deviation of the received message from the
transmitted one. Next optimization with a variable
corrector as in Price and Green (Ref 8) Is considered
The corrector parameters are varied in eiccordance with
data on fading obtained during the courtie of operation.

TIKXT: The capacity of a system in which a mingle message in
trAhmanitted over n paths -is calrulated ou the- basis of output
sigisal formation by a mocha-nimm similar to that in multi-ray
transmission of radio waves. For n a I the problem was
investigated in detail by B.S. Tsybakov (Ref.l: Radiotekhnika i
*Iektroniks, 1959, Vol.IV, No.9). The fading in each channel in
assumed dependent on that in the other channels, while the
r
,:spective noises are independent. The rate of transmission of
formation over a channel with random fading is equal to the rate
of transmission of information for a channel with fixed fading,
averaged for all possible values of fading. Assuming Rayleigh
fading and Gaussian input signal, an expression is found which can
be expressed in simple form only for white noise. The solution can
be modified to express uncorrelated fading.

ABSTRACT: The author describes a method for matching the vectors of the source and
the chanvwl with a piecewine-weighted mean-square criterion of reproduction probability.
This method, which includes optimal linear coding (pre-distortion and correction) and
optimal transposition of the frequency bands of the components of the vector communica-
tion, psoven to be the best in the class of possible tinear transformations. It provides a
frequency-weigbW zne=-squars deviation no greater tham at any other linear methods of
coding and transposition. A procedure its presented for finding the optimal characteria-
tics of the coder od decoder with correlated components of the vectors of oommunication
od not" wd In do presence of linear distortions in the i4mmeel. Author thanks M. S.
