TITLEi Experimental smelting of ball-bearing steel by using a refusing method
employing a now technology

ABSTRACT: A now technology for sme ting ball-bearing steel employing a refusing
method was developed. Thie moth'64-IT-Vased on the results of an earlier inveBtigation
by G. N. Oyke, P. A. Matevoeyan, 1. 1. Ansheles, i dr. (Novaya tekhnologiya vyplavki
sharikopodshipnikovoy stali, Metallurgizdat, 1962). The salient points of the new
technology aret 1) the furnace charge consists of 100A ball-bearing steel scrap; 2) to
insure donulfonation, the slag io reduced with pulverized coke only; 3) the oxygen
concentration is maintained by additiona of rod hot bauxite* After tho abovo throo
steps, the steel is evacuated and poured in the ucual way. A comparison of the now
method with older ones is presented (see Fig. 1). It is concluded that the now method
yields ball-bearing steel of higher quality.

ABSTRACT: The results are reported of an experimental investigation of the
accuracy of operation of the capacitors connected to the feedback loop of a d-c
amplifier which is simultaneously used as an integration unit. Ten I -to F (t 0. 510);
capacitors connected individually by relays were used for information storage; it
!was noticed that their stored voltages suffered,after switching,up to 10-1310 loss.
As a result of studying the causes of leaks, an improved circuit (see figure) with

ABSTRACT: One of the physical methods of detecting the presence of the
unpaired valence electron in free radicals is the method Df
electron paramagnetic resonance (Ref 1). In this way a
number of stable hydrazine derivatives was investigated such as
the a,a-diphenyl-p-picryl hydrazyl and similar hydrazy1s
(Refs 2-6). The application of this method permitted the -n-
vestigationsof the influence of various substituents --ir- the
free radical upon the unpaired electron. As initial prod-u-,t
served the polyhalogen derivatives of a,a-dipheny1-3-Di-.ry!

ABSTRACT: In continuation of the papers of references 1, 2 the authors
try to explain the possible influence of the chlorine- and
bromine atoms on the exchange interaction of the unpaired
electron of the nitrogen atom if the halogen atom is in posi-
tion 4 of the biphenyl eater of the radical (II). Compounds
(Na), (IIb), (Ilv) were synthesized for this purpose. These
free radicals hitherto not described in publications were
obtained according to the above scheme. The new radicals are
very stable compounds which do not change for months even in
air. They crystallize from chloroform ether in the form of
almost black prisms, they are, however, dark violet, in aromatic
hydrocarbons and in chloroform. The radical (IIa) is obtained-
in two forms by the oxidation of the nonsubstituted picryl
Card 1/3 hydrazine (VIII). After the end of the oxidation first the

radical (IIa) separates from the chloroform ether solution
in prisms of almost black color (melting point 90-910,
yield 10-15%); after some hours a finely-crystalline precipi-
tate of brown color separates from the filtrate on standing
at a low temperature (melting point 16o-i6io, yield 25-30%);
it dissolves in chloroform other with dark violet color.
When vaporizing theosolution,arystale-of the radical wlth a
melting point 90- 1 are separated firati on standing at a
low temperature the product with the melting point 160-1610
again precipitates from the mother liquor. The black and
brown product have the same empirical formulas. It was found
by the method of paramagnetic resonance of electrons that
the exchange interactions of the unpaired electron in the
biphenyl radicals which are in crystalline state increase
to a lesser degree in the transition from the nonsubstituted
.radical to the substituted one, than is the case with the
corresponding phenyl radicals. It may be concluded therefrom
Card 2/3 that the biphenyl residue in the radicals (II) investigated

transfers the influence of the halogen atoms to a lesser
degree in the crystalline state than the phenyl in the
radicals (I). On the basis of this method it was thus found
that both products are free radicals; however, they have
a differePt structure in the crystalline state since their
A H are d4fferent. The measurement of paramagnetic resonance
was made by A. K. Chirkov. There are 3 tables and 6 references,

and rather stable radical has hitherto been investigated only little. The
authors did not know its synthesis, and only its paramagnetic properties
have been mentioned in publications. In order to determine the dependence
of the free hydrazyl radicals upon their structure, the properties of
the carbazyl radical and of its 3-chlorine and 3-bromine derivatives
viere investigated and compared with those of the corresponding diphenyl
radicals (Refs. 5 and 6) (Table 1). The authors eynthesized the following
free radicals of the carbazyl series, which had hitherto not been describ-
edz N-(3-carbazyl chloride)-picryl nitrogen and N-(3-carbazyl bromide)-
picryl nitrogen. By means of electron paramagnetic resonance it was found
that in weak fields (AH, = 20 oe), N-carbazyl-picryl nitrogen and its
3-ohlorine and 3-bromine derivatives contained in crystalline samples in-
teract less than a,a-dipbenyl-p-picryl hydrazyl and its halogen deriva-
tives. The authors discuss the constituting and spatial factors affecting
the properties of carbazyl radicals. A reaction formula is given for the
synthesis of N-carbazyl picryl nitrogen and its halogen derivatives. Two
figures illustrate the results obtained, and Table 2 gives the constants
of the compounds synthesized. There are 2 figures, 2 tables, and
