ABSTRACT: This is a brief generalreview of work done by the Welding
Section of the Kuybyshev Oblast' NTO. Welding sections have
been created at different plants. Ab out 50 delegates from'.
'plahts and institutes of Kuybyshev an d its oblast' participated
in a conference on welding. Engineer I.M. Ilyukhin made a re-
port - "Arc Welding of Thin Parts in Carbon Dioxide" and told
of his plant's experience. Engineer V.I. Stolbov repo)rted,on
his P~antls experience in welding the
' new aluminum-manganese
alloy 'AMr-6T" Engineers

TITLE: Investigation of the electric resistance in projection welding -n
models
PERIODICALs Avtomaticheskaya svarka, no. 3, 1961, 48 51
TEXT. The article presents data on electric current distribution field
studied on flat conductive paper models simulating joints between halves of bal
bearing separators being joined by projection welding. An electric A-12 (ET-12)
integrator was used for the quantitative evaluation of the accuracy of the zethsd.
Reference is made to a previous work in which it had been proven that flat pap-~-.r
models are suitable for qualitative studies of current distribution in parts being
joined by spot or projection welding (Ref. 1- M.D. Rudman, Issledovaniye polys
toka v detalyakh, svarivWftykh tochechnoy svarkoy, na ploskikh modelyakh. Trudy
KUAI, vyp. VII, 1958) and to a work in which the curreni distribution had been
determined in a plate with two electric contacts applied on one axis with the aild
of an 0FAA-6/51 (EGDA-6/51) integrator [Ref. 2z - F.F. Fillchakov, V.I. Panf ch-ish-

was equal to 62.3% of the total resistance of the entire model when i~ha mcde'L was
solid, or 65% when the model had a cavity. In paper models with a cavity, the
corresponding resistance value on a projection with a civity was 69%.--Tbus the
data were sufficiently close. Engineer V.P. Vezelcv i:~ mentioned having prepared
programs for the electric integrator. There are 2 figures and 4 Soviet-blc-, ref-

TTTME: Results of stand test of no. 407 ball bearings'with welded ball cages
pERIODICAL: Avtomaticheskaya svarkay no. 4j 83 85 1161/
PERI
'TM.- Several batches of no. 407 ball bearings with welded ball cages have
been vubjected to long-time tests on a test stand at a bearing plant to decide if
it would be practical to replace th6riveted ball cages by welded ones. The test
ball cages had been welded on a MPPInW-600 (MRIPSh-600) welder using three different
process variations with different heat separation intensity, as had been described
previously [Ref. 1: M. D. Rudman, "Avtom..svarka", no. 2, 1960]. The ball cages
were oickled in a sulfuric acid solution, rinsed in a soap solution and dried by
air blast prior to tests. The maximum value.of the welding current pulses J,niever7
join, and its duration were determined by oscillograms. The tests consisted n
r.iraning with 5,000 rpm under 819 kg radial load, with spindle oil as a lubricant.
The results are given in a graph and a table. The best results were obtained in
'the 3rd process variation- welding current amplitude 6,030 amp, contact pressure
950 kg, 9th stage of the welding transformer, welding pulse duration of 0.25 see.

ABSTRACT: Projection welding of bearing separators has been.
studied since 1954 at the Kuybyshev Aviation Institute&
Preparations are now being made at a bearing plant to
start projection welding of separators of "Nr 407" .
ball bearings. The projections on the separator halves
are formed in the process of making these halves in
multispindle presses. The projections which are made
on one separator half only, eliminate the necessity
of punching holes for rivets, and thus simplify pro-
duction and cut costs. The welding process is carried
out in special welding dies (Figure 1) under 850 kg of
pressure. The process is described in detail. The com-

ABSTRACT: Descriptions are provided of fans (F) built and tested at the.
Metallurgical-furnaces Laboratory of the Zhdanov Metallurgical
Institute. The high-pressure F create a head of 1150 mm
water, have rotors (R) of 800 mm diameter with 16 blades curving
rearward, and deliver.10, 000 m3/hr. The R operates at 2840
rpm, and the motor develops 30 kw. The R of high-tempera-
ture F are made of special Cr-Ni steel; the shaft and bearing
housing are water-cooled.. The R having a 400-mm diameter
has 12 blades and operates at 1000 rpm; the- F, with 110 mm
head of water, delivers 800 rn /hr. The motor has 1. 5. kw
power. The F were tested for 10 hours of continuous opera-
tion with air heated to from 100 to 9800C in coil-type electrical

TEXT. This is a brief description of the use of explosive forming methods
in metallurgyq based almost exclusively on Western works. The main ad-
vantages,of the process are said to be (1) Accuracy and consistency;
(2) potentially high surface quality; (3) production of complex shapes
in a single operationg and (4) shaping of new alloys unsuitable for
fabrication by conventional methods. The following variations are des-
cribed- (1) the Dynapac process, (2) closed explosion chamber with no
punch, and (3) no explosion chamber and no punch. These are described
and. illustrated, suggesting their fields of applicability. Equations
are given for calculating the pressure obtained with an explosive charge
and the critical pressure of deformation, together with a short discussion

A poliomyelitis epidemic involving 2.334 cases (23.8 per 100,000) is described. The
epidemic was more extensive in the country (26.2 per 130,000) than in Budapest
(13.6 per 100,000). The northeastern part of the country suffered most. County
Hajdu-Bihar had the highest attack rate (88.2 per 100,000). The case incidence.
which at the beginning of the year had already been relatively high, began to rise
rapidly during May and attained its maximum in July. The rapid rise of the curve
was followed by a sudden fall. The age-specific attack rate was highest (284 per
100.000) in the group of the one- to 2-year-old children. The attack rate was 194

37_~3
per 100.000 for the infants and 73 per 100,000 for the 3-6-year age group, The
proportions of the 3 -6 - and 7-14-year age groups have Increased since 1956. The.
general case-fatality rate was 6.11%. The age-specific caae-tatality rate for in-
fants exceeded 9%, and decreased with increase of age until 14 yr. The group
above 15 yr.- displayed the highest case-fatality rate. (L. 7. 8)

T;iv age-apecific morbirlity was cnIctilated for measles, whoopingcough, diphtheria.
4rarlet fever and poliomyelitis for 1931-311 in(] 194.9-54. The morbidity rate was
fmind to have 4hifted toward the younger age groups Lit all the diseases examined.
For each of the 5 dkeiscq the age wat; determined at which morbidity reached the
maximum. The shift of the maximum incidence toward the younger age groups not
only manifested itself in the mean values for each of the 2 periods studied, but was
consistently revealed in the years following World War U. It was most marked in
whooping cnugh and poliomyelitis. In the former condition, morbidity shows the
absolute maximum in the first year of life. so that it is advisable to start vaccina-
tion in early infancy. Studying the relationship of age and the movement of epidemic
cycles, the curves for the individual age groups were found to be changing in all 5
diseases in almost the same proportion throughout the cycles. This appears to be
in contradiction to the generally accepted theory of cyclic variation in diseases of
the respiratory tract.

Hungary experienced the largest poliomyelitis epidemic in recorded history in
1957. There were 2,334 notified cases, 23.8 per 100,000 of population. This was
twice as large as any previously recorded figure. 143 died, the mortality being
6.1% of cases and 1.5 per.100.000 of population, The peak incidence of the Infec-
tions occurred during the summer and early autumn months. The epidemic was
particularly severe in the north-eastern counties, where morbidity rate of up to
88.2 per 100,000 was encountered. 61% of all cases occurred in children under 2
years of age. The mortality was highest - 10.4% among 125 over 15 years of age,
followed by 9.3% among 333 under I year of age. Of those nursed at home 19.1%
of 63 died and of those treated in hospital 5.8% of 2,271 died.
