ZX2-.~ Based on the chemical.reactions of the decarbonization of ferrochrur
w I tIt -,. oxygsn blown into the converter, the TsNIIChM established the technology for,
thi a prooess consisting of three phases: First phase: blowing oxygen through
Iretal, he.~~tlng the metal above,1,700'C and accumulation,of oxides' in the n-
Co
v~~rterv set.-ond phase: blowin oxygen into the converter over the metal, result-

ing in the oxidation, o f the main carbon mass,until a carbon content of 1.0
`.2% Is 3-41-tained with heating to 1,750 - 1,8000C.-. u7,ird phase: producinga vapa-
u-um In -,he bal~,h and blowing a smaller amount of oxygen into the converter, while
the ~I&rbcnscnzent is r*educed to 0.2 - 0.5%. The converter is in the same posi-
,~Ion as In phaze 2but it is covered with a vacuum chamber. The technology, has,,

or blowing 4' tons,.of ferr6chromium, wi th
-casings: one with-a-ba.91p.lining for the melting and an outer casing for the, vac-:
uum process (Fig. 2).. The mq~fibd*-has,,been,.introduced-in the Aktyubinskiy.,zavod
ferrosplavov,(Aktyubinsk Ferroalloy Plant)lby October 1958, which produced a met-
al with alower Si-content~(less than 1.0%).than in the,Chelyabinsk Plant. The
method applied was also different. The converter was lined with periclase~spinel-
lide brick, 230 mm thick,mbich is rapidly.corroded by slag when blowing ferro-
chromium with a Si-content above 1 5 - 2.0%. This plant, therefore uses ferro-
chromium containing not more than 1.0% Si, which however results in,an increase_
I Y
in chromium cinder W t 80 meltings can be.carried.out. This

is still not sufficAnt and attempts are being made to'Toroduce a lining g ICodf.or' J
at least 100 melting', preferably from melted magnesite. When melting ferro7-,.
chromium with a highbr-(6:5 -'8.0%) carbon content, oxidation in.the bath starts
at a lower temperatAe,.when the metal still.is not liquid enough. In -this case: J_
the
blowing has to be cairied out somewhat slower. In May:1959.,..the costof coil-,
verter steel produced with this method proved.to be 200 rubles lower than.the Cost
~of medium carbon ferto-chromium produced by the silico-thermal:method. Further
improvement can be obtained by using XF4 (Khr4) grade-ferro-chromium with.a lower;-

Improved Needles with Radioactive Cobalt"
Sof3.a, Rehtgenologiya i Radiologiy Vol 5, No 2, 1966, pp 117-121-
Abstract, [authors' Russian and English summaries, modified):. By pinning'the
base of the tongue, the floor of the oral cavity,.tbe vagina, the female
urethra, the anal region, etc.it is not always possible to,.observe.the, re-,
quirement that the irradiated region be surrounded an all sides with needles
in order to compensate for the reduction of tbe~dose in the proximity of the
needle ends. To avoid the inconvenience of pinninG in relatively, inaccessible
60 needles with higher 1i
regions, the authors proposeusing Co- near.activities
at one or both ends than at their middle part., The authors obtained such
needles by placing cobalt-nickel pins with different linear activity in steel
L ters for- the Co 60 needles. The distribution of the dose around, the. ordi-
nary and the modified single~needle, and from implants with such needles, is
illustrated,with,equidensity curves.. Using the,modified.needles gives a suit-
able distribution of the.dose in the implanted region, employing only parallel

711. THEINFLUENC OF A SINGLE OR PROLONGED ADZIMNIiTR~TIONOF
ACTH ON THE SECRETION OF CORTICOSTEROIDS BY THE ADRENALS
IN RATS (Russian text) - Sakh a t s k aya T. S. All-Union Inst. of Exp.:
Endocrin., Moscow - PROTM.ENITORR.
-1959, 2/6 (51-55)
A single injection of ACTH in a dose of 0.5 to 4 U. into the jugular vein of hypo-
physecto;nized rats raised the corticosterone content of the adrenal vein blood to
the level.of.that in intact rats. Hydrocortisone could not bedetected. Similarly,
after prolonged administration of ACTH no quantitative change in the secretion of
corticosteroids was observed: after 16-30 days, of injections, corticosterone only
was secreted. Dilman Leningrad (S)
