TEXTs The polymerization of aorylonitrile in malt solutions and in,dinothyl
formamide (DXF) was studied during irradiation by a 3OO-v ultraviolet laxpo!
The following salt solutions were used (in % by weight)s (a) 31.25 C&012
+ 31.25 ZnCl + 37-5 9 01 (b) 62.5 ZnCl + 37-5 B 0. A solution of
2 2 2 2
1.537 g/liter Ce(30 acidified with 26.82 g/liter HClj served an
4)2*4H2OP
initiator. The volume ratio monomer i initiator # solvent was I s 3 t 15*
The conversion was higher in ZnC1 than in ZnCl + CaCl # reaching more
2 2 2
then-80% after 6 hre. Molecular weights of more than 400,000 were attained
in CaGl + ZnC1 but were a little lower in Zn0l In DMF the degree of
2 2 2'
conversion after 10 hre was only about 25% at OOC (optimum temperature)t
and the molecular weight attained,only 26#000 - 34,000. Rates of polymeriw

Orig Pub: Izv. AN UzSSR. Ser. biol. 1957, No 2, 25-32.
Abstract: Data are given proving, in the author's opinion,
that in crossing different varieties of cotton-
plants within the limits cf Gossypium hirsutum
species, an admixture of maternal variety pollen
causes it to interact with pollen of another var-
iety, which creates a more normal physiological
medium for germination. The presence of alIqualit-
ative interaction" of different varieties of pol-
len bears witness to the plural character of ger-
mination. There is no statistical evaluation.

TEXT: Three cuts and a number of additional points of the ternary system
TaCl 5 - FeCl 3 -NaC1 were investigated (Fig. 1). The following points of
four-phase equilibria were determineds E, with about 2 mol*% of Tacl 5

point P with 3 mole% of TaCl 5' 49 mole% of NaCl, and 48 mole% of Foci 3 at
1470C (Fig. 2). The system TaCI 5 - N&FeC1 4 constitutes a quasi-binary cut.

expressed by the equation log p - 3180 + 7.5. A vapor pressure of FeCl

is practically absent. It follows from the tensimetric investigations
that pure Tantalpentachlorid free from iron or aluminum chloride can be
obtained by distillation in the presence of sodium chloride. The boundary
system Fecl 3 - ZrCl4 and six cuts of the system ZrCl 4 - recl 3 -NaC1 were
studied. At 3000C, this system forms a eutectic with 20 wt% of ZrCl 4 and
80 wt% of FeCl 3' In the ternary system, the following points of four-phase
equilibria were determined (Fig. 3)t E 2 with 28 wt% of NaCl, 68 wt% of
FeCl 3' and 4 wt% of ZrCl4 at 1350C; E 1 with 8 wt% of ZrCl 4, 68 wt% of
FeCl 3P and 24 wt% of NaCl at 147OC; E with 9 wt% of ZrCl V 70.5 wt% of
FeCl3, and 20.5 wt% of NaCl at 1450C. Tensimetric measurements of three
samples (300-6900C) showed that it is not possible to distill zirconium
chloride free from ferric chloride by adding NaCl. B. G. Korshunov is

T,--,,'kT: CracR for7rarion In weld joint craters depends on the pool volume
a.nd the metal cooling rate. The cooling rate can be reduced by ensuring tile
gradual decrea.-,e cif the current voltage. Tests were made with the aid of a
welding rheostat of power supply source 'V~7"-350 (IPK-350) with rectilinear or
exponential current decrease. The electric-driven stepped rheostat is corlected
to the magnetizinE circuit of the saturation throttle. It has 11, steps of 300
ohm total resistance. The consecutive connection to the circuit of different
resistances, ranging from R, - 1.43 to R11, u 152 ohm, ensures changes in the
welding current, which approach the rectilinear law. These changes of resist-
ance values regulate the rotation of the rotor and the time of wrelding-up the
crater. Best results are obtained if the welding-up time is 8 - 10 sec. The
described mechanism. ensuring the rectilinear decrease of welding current, can

ABSTRACT: Several methods of stabilizing.the a-c arc in argon-sbielded are welding
of such low-alloy structural steels as cromansil, VLID, d VKS1 have been tested..
A chemical oxidation of the base metal and filler e_Xd the addition of 0.3-1.0%'
oxygen to argon ensured a satisfactory, stable arc in welding with or without filler
wire. No difficulties were encountered with oxidation. At an oxygen content in
argon not exceeding 1%, the life of the tungsten electrode is not shortened. oxygen
introduced into a protectIve atmosphere decarburizes the weld metal. The degree of'
decarburization depends upon the composition of the base metal and filler wire.
The decarburization of VXS1 steel varies from 0.02% in welding without filler wired

ABSTRACT: The use of high-

hydraulic buckling of flat sheet specimens via a round orifice. In testing the base
metal the purpose is to determine the true peripheral stress or, as a function of

ABSTRACT: Three Cperstrength steels, LIP, EP257~~, and SP43Nave been tested for
the susceptibility of welds to delayed =fauriT.-The quality of shielding was foun6
to be the primaryfactor affecting the susceptibility to delayed failure. Under
shielding conditions approaching those of a controlled-atmosphere chamber, a-c
yields velds of the same quality as d-c does. As the shielding becomes less effi-
cient, the quality of the a-c welds drops more rapidly than that of d-c welds.
The VLlD*steel welds made with conventional shielding (argon consumption 12 I/min:
with d-c failed under an average stress of 48.5 kg/mm2 compared to 32 k;/MM2 for
welds made with a-c and the same shielding. The use of a-c of a higher frequency
with an almost fully rectified half-period of reversed polarity improved the weld
quality al st to the same level as that of d-c welds. The resistance to delayed
fa-=ure can be greatly improved by holding the welds (without tempering) at room
