TEXTt The views on the theme in the title are directly contradictory (Refs. 6,7)
in the few (2) relevant works. In their experiments the authors used commercial
(,,,80r%) and purified (96%) boron hydrides. They used the micropolarograph of
Heyrovskk, model M-102 with a dropping mercury electrode. For HaBH4 in NaOH they
have found a single wave, namely that of the ion BH~. Its nature was determined
by further experiments (Fig. 1, Table 1). The pasition and character of these
waves remain practically unchanged through variations in the concentration of
boron hydride and through changes in the compobition of the background. This
result disproves the data of R. L. Pecsok (Ref. 6). The authors studied the
dependence of the height of the boron hydrlde wave on the concentration of BH~
ions. The dependence is linear between 10--'~ and 10-1 Moles/I. The limiting
current here is no complete diffusion current. The metallic boron hydrides

decompose relatively quickly in aqueous, especially in acid solutions, so that
the polarographing is made very difficult. Therefore, the solutions used were
prepared with the use of the relevant alkalis and alkaline borate buffer
mixtures. From this it was established that, for the same concentration, the wave
height is highly dependent on the pH in the solution. With a pH above 12.5 the
boron hydrides are relatively stable, but the wave was practically missing alto-
gether. Thus, it follows that in reality the wave does not belong to the BE4 ion,
but to one of its hydrolysis products. These occur in several stages in one Of
which diborane is given off under certain conditions. However, diborane can
react with alkalis and form the so-called hypoborates (see scheme). Gaseous
diborane was passed through concentrated KOH-, NaOH-, and MOR solutions when
cooled. The resulting hypoborate solutions showed the same wave with El /2 -
= -0.6 v. The dilution of these solutions led to a proportional decrease in wave
height. When the solution is left standing, the height of the "hypoboraten wave,
exactly as the "boron hydride" wave, decreases according to an equation of the
first order (Ref. 8). When the solutions are boiled and strongly acidified, the
wave disappears after the destruction of the hypoborates. Thus, the "boron
hydride" wave is basically a "hypoborate" wave. It is difficult to say to which
of the 3 hypoborates the wave belongs. However, it cannot belong to the BH-(OH)

ion. It is more likely that the BR(OH)3 ion is responsible for the wave. The
electrodic reaction which the said wave causes can obviously not (contrary to
Pecook) be brought about by oxidation of the B ions, but must be due to the
oxidation of the hypoborate ions (see scheme)."if the two schemes set out, the
second is more likely. The following are mentionods D. IlIkoviff, A. F. Zhigach,

hydrolysis of Na-314 41 KBIi 49 LiBH 49 and 05BH4solutions of these boron
hydrides were examined polarographically in aqueous solutions by using a
recording polarograph (type 7-77-46, "orion", Hungary), a mercury dropping
electrode, and a calomel reference electrode. The boron hydrides were
prevented from decomposing by being dissolved respectively in 0.2 M NaOH,
KOH, and UOH. Investigation of the polarization within the range +0.2
to -2.0 v at room temperature showed that, unlike what had been found by
it. L. Pecook (see below), the three boron hydride3 Cave rise to the aame

wave amplitude decreased with time. This process can be accelerated by

acidification, heating, or catalysis. Different backgrounds did not
affect the wave. The wave E 1/2 - +0-105 - 0.013 pH found by Pecsok is
attributed to the anodic dissolution of Hg in an alkaline med4um.
Results: (a) Change in pH and temperature (15-350C) do not affect the

wave potential. The wave amplitude of NaBH and XBH n the range of
-3 -4 4 4
1-10 to 1.10 moles/I is a linear function of the concentration of
boron hydride. (b) The wave amplitude decreases with increasing PH. kt
PH >12.5 - i.e., if no hydrolysis takes place at all - no further waves
will appear. Polarographic analysis of Cai12 and BA showed no wave with
the first compound, but E 1/2 - -0.65 v when B2H 6 was bubbled through NaOH
or KOH. From this it is concluded that the wave is due to the resulting
hypoborates. Polarographic results obtained from stepwise hydrolyzed
LiBH 4 and from NaBH(OCH 3)3 indicate that the wave is not produced by the
31-H- ion but by the BII(QH)- ion. Analysis of the polarographic kinetic

curves for NaBII 4 and KBE 4confirmed that the hydrolysis of these compounds
-ollowed the theory of the kinetics of consecutive processes. There

ABSTRACT: The Toul_Dostal method of synthesizing selenium trioxide, involving
the dehydration of anhydrous solonic acid with phosphorus pentoxide: H2SO04 +
PZ05 --) Sao3 + 2HP0 3' was improved to give a more reliable and suitable aethod
by omitting the use of a drying chamber.
Phosphorus pentoxido and 98-100% solanic aced (without H 2 Soo3) are mixed in
a 12 : 10 weight ratio in the react-or section of a complote3,y closed glass
apparatus. After sealing of the leading tube the apparatus is connected to a
vacuum pump, and the reaction mixture is heated to 140-145P. At this
tomparature and a pressure of 1-2 mm Rg the basic mass of selenum trioxide
1A
Is Separated. SeO vapors are condensed In a collector which Is cooled with
running vat'or. PIX completion of the reaction necks to the collector
are sealed and the cooler is removed. The selenium trioxide in the collector

ABSTRACT: The author studied palladium-copper alloys which were
prepared, homogenised and annealed in vacuo. Samples of
alloys of the following compositions were prepared:
14.5% Pd, 85.5% Cui 15.5% Pd, 84.5% Cu; 16% Pd, 8496 Cu;
16.5% Pdl 83.5% Cu; 17.5% Pd9 82.5%. Cu (all proportions
are given in atomic 0percent). Cast ingots were
homogenised at 1000 C for 10 hours. The in6ots were
rolled down to a thickness of 0.2 mm in several stages.
In between thes 8 stages the samples were annealed for
one hour at 800 C and quenched in water. The author
measured the Hall constant R by the usual compensation
method (error + &16). The electrical resistivity Q was
measured by megns of a Thomson bridge to within 0.9%.

ordering of the alloys and on decreasing it. In both
cases values of R and (I were found to lie on cur-,j-es
of the type shown in Fig.l. The degree of orderin6 in
the alloys was not measured direczly; the author took the
value of the electrical resistivity as the c-riterion of
ordering (Ref 5). Fig.1 gives the dependences of R and

content in ordered and disordered states. Fig.3 gives
the relationship between R and 9 as a function of
the degree of ordering for several of the alloys studied.

There are two groups of curves in Fij;.3: group a represents
the ordered state; group 6 - the disordered state.

ordered state of the alloys. Fig-5 gives the dependence
of ot (where ot is the angle of the slope of the straight
lines Rt = f(6e t) ~ on the amount of copper in the

1. Transition from the disordered to the ordered state
in palladium-copper alloys is accompanied by an increase
of the range of variation of R and a decrease of the
range of variation of
2. Variation of R andp~ in ordering of the alloys
cannot be explained on the basis of the elementary theory
of metals which relates R, () and electron density.
3. Changes iv. the ionic distribution in the crystal
lattice of the palladium-copper alloys', which occur on
ordering are accompanied by an increase of the number
of positive current carriers and an increase in the
number of centres which are responsible for incoherent
Card3/4 scattering of these carriers.

S(DV/126-6-5-18/43
The Effect of Composition and the Degree of Crdering on

4. The observed linear relationship between R and
during the process of ordering is due to the constancy
of the ratio of the numbers of positive current carriers
and incoherent scattering centres produced during
ordering.
5. The latter ratio varies with the alloy compositior.
6. Departure from linearity of the relationship between
R and q was observed at higher degrees of ordering;
it is due to interaction of ordered regions.

ABSTRACT: The authors describe basic designs and subsequent In-plant modifications of
KAPZ-5 and KAPZ-7 conveyor type annealing furnace systems, capable of annealing sheets~
0.8 to 3.5 mm thick and -with maximugi dimensions of 2000x5OOO and 2000x7OOO mm respec-
tively. Two chain.conveyor systems~~owered by a single P-91 32-kw d-c motor, transport
each sheet separately through a rectangular vertical hot air furnace chamber. The sheet
suspension systeT to treated in detail. The overall Installation Is easily Incorporated Into a
factory flow linel \Productivity is 1.5 to 3.5 t/hr, depending on the thickness of the 7000 mm
sheet: T-Ye-rej ct factor averaged 0.22%. Temperature gradients across the annealed sheet
did not exceed 3 to 6C. Major components of the system are described and Illustrated. Ma-
terW specifications are given for parts subject to significant wear and temperature variations.

ABSTRACT: The article considers d longitudinal impact at the butt end
of a sernik- int knit-2I y long I)ar which causes an elastic -plastic
deformation. The c-la~-k 1~rno oi the bar is considered to be
variable, with eithui- rcasing or increasing modulus of
elasticity along the direction of the wave propagation. The
subject work differs from that of 1-1. A. Rakhamatulin's
(Priki. matem. i M-khan. 1950, Vol 14, Nr 1) by the choice
of the function giving the variation of the stress IT against
the deformation6 ft is assurned that all the characteristic
properties of the (r versus -6 function pertaining to
static loading and unloading remain valid during impact action;
