TEXT: The representation of the seismic load on a structure, whose
calculated scheme is taken to be a console embedded in the basement,
as a series with respect to the forms of viblations is incorrect,
despite the fact that it is taken as the basis of standards
(SN-8) to 57. The elasticities arising in a structure are neqtrali-
-zed by two systems of forces: by the inertial load of the relative
movement of the console's points and by the inertias of the abso-
lute movement of the structure together with the ground. The magni-
4.
klude of the calculated seismic loads depends on the coefficients
KC and B(T), whose customary values have not been adequately sub-

stantiated. The seismic load formula, proposed by I. L. Korchinskiy,
takes into account the inertias of relatj.)re movement, but it abso-
lutely disregards the inertias of the absolute movement of a struc-
ture as a rigid whole. The mistaken position of I. L. Xorchinskiy
about the proportionality of the accelerations of different pivotal
points to the ordinates of the forms of the vibrations at the same
points is also adopted in A. G. Nazarov's method. Or, the basis of"
t-'I'le concept introduced by S. V. Medvedev about action spectra, the
i3oismic load at a certain point of a structUre, bearing n cent-e-red
masses, can be represented as the sum of thE: loads with resPect to
different tones of vibration. There are no grounds for reckoning
that this expression coincides with the true value of the seismic
load at a certain moment of time. Any method devoid of these errors
should be founded on the use of a formula, oonstructed on the basis
of the following assumptions: 1) The inertias are proportional to
the 'lexures according to the main form of -the free oscilIations;'
2) the forces of inelastic resistance at the moment t = t 1 are neg-
ligibly small; 3) the accelerations of the relative movement and the

ground movement can be considered as independent quantities, which
may be added algebraically; and 4) the vibrations of structures
arise from the flexures, relative to the basement and the rotation
of the whole structure, together with the basement around the hori-
zontal axis, situated above ground level., by virtue of which the
structure's basement shifts in relation to the ground, when the
relative movement of the basement and the ground movement may also
be sub4ect to the principle of superposition. /-Abstracter's note:

TEXT: During a given basement shift; the forced oscillations of a
frame system with distributed masseEl can be represented by means of
a system of differential equations in individual derivatives whose
number equals the number of frame elements. In addition to this
one equation in a vectorial form may be considered in place of the
system of equations. Any vector. being a solution of this equa-
tion, can be resolved into a series for the vectors which are solu-
tions of the correspondingly.similar equation. In view of the ortho-
gonal nature of the solutions of a uniform equation, the coeffi"
cients of resolution are determined from the system of independent

it is shown that the influence of the vertical weight displacement
is negligible for frames with rigid interties. For frames with
flexible interties this influence is substantial and should be ta-

TEXT: The authors have investigated the reactions of hexaethyldistannane
with certain or.-anic haloid derivatives in evacuated ampules at elevated
temperatures. It has been shown on. the example of bromine- and iodine-benzene,
that halo-ene, bound to the benzene 2-Ing, is not detached by the hexaethy"-
distannane, when heated to 180-19000 for a -Deriod of 20-30 hours, In all other
cases it was found that the rate and direction of the reaction depends on the
nature of the haloid derivative. The hexaethyldistannane was faland to react
easiest with triphenylchloromethane! (4.5 hr3 at 1000C) and with n-toluenesul-
fochloride (13 hrs at 1000C). In the first case the reaction takes place with
the formation of triethylstannous chloride (yield 61.7;D' of the theoretical), and
triphenylmethyl radicals. The pre-cience of the latter wa;a proven by the
electronic paramagnetic resonance method. Triethyl stanaous chloride (yield

The Reaction Between Hexaethyldist4umane and Orga!.1lic Haloid Derivatives
reactions discussed here, based on previously made assumptions (Ref. 2, the
author), that :reaction (2) is a catalytic one, just as the disproportionation
of the hexaetN~ldipliimbane is (Ref, 1-3, the author) . This assumption was con-
finfidd'by the thermostatid action of the raixture' dexdetl~yldistannane and
triethylstannoils chloride'At 200'2100C (1.0 hours, molar ratio 1:2). Reaction
(2)-takes place more energetically'in the presence of 3 moles of dichloro-
ethylattimn te and 2 moles of hexaethyldistannane (for a period of 1 b , at
2000C). *The-f.:)rmed tetkaethyl6tannate reacts with the ftchloroethylstannate,
forming triet4ylstexanous'dhloridei 200,5)6% + 3(C2Hci)2SnCl2 6(C2H5)3
SnCl + S)n. N. It is stressed that equ1ition (2) desci.-ibes only the final
result' The reaction mechanism is thoughr, to be complex from the following
indicaii6ns: during the reaction intensivo wine-colored,, presumably high-
molecular compounds are formed, decomposing toward the end of the process, the
stannous chloride is thought to play an important role J.n equation (2)p
usually identified when conductingthe disproportionation in an excess cf
dichloroethylstannate. It was established that the Snc'.'.~ can cause changes not
only in the he.xaethyldistannane, but also in the more stable tetrealkyl.

The Reaction Botween Hexaethyldistannane and Organic 11aloid Derivatives
derivatives of the tin. The folloiring reaction is given as an example of the
thermostatic action of equimolar qxiantities of tetraethylstannate and SnC15~
(for 10 hours at 23000: 2(C2H5)4S" + 2SnC12 2 (C 2H 5) SnCl - (C2H~)2S~C12+
+ Sn. (4) also taking place with the forruition of dark-tea ool.or'ed in or-
mediary compounds. Another fact proving the complexity of the reaction is
given as being the fact that catalytic quantities of (0~15) SnCl and (C-245)2
SnC12 (2/-o of the weight of hexaetbyldistamnane) do not brirg about its complete
conversion according to equation (2). It is pointed out that the interaction
of the hexaethyLdiplumbane with an excess of triethyl lead chloride triethyl-
stannous chloride or diohlorodiethylat.annate, takes place! quite differently.
In this case the disproportionation reaction is completely suppressed by the
complex oxidation- reduction process. In conclusion the authors state that
investigations are still being continued in this field, There are 3 Soviet
references.

TEXT: The author recorded the absorption and luminescence spectra
of nine derivatives of naphthalene in solution at various values of
the solution PH. Ther-e derivatives were: B-naphthol, a-naphthol,
1,2-naphthol, 1,5-naphthol, 1,7-naphthol, 1.8-naphthol.
2,3-naphth4oll, 2.6-naphthol, 2,*,7-naphthol, The absorption. and
luminescence spectra were recorded with a spectropbotometer CJ-4
(SF- 4) . A photomultiplier 03Y.-18 (FEU-115) was used as a receiveri',/
the photomultiplier signal was amplified and recorded automatically
with a potentiometer 9MID-51 (EPPV-51)~ A mercury lamp C(MW -1000

naphthols wer-e in ionic form and their absorption and luminescence
spectra were shifted considerably towards longer wavelengths; in
most of them the structure disappeared and the spectra were
broadened. The author determined also the ratios of the relative
luminescence yield of undissociated molecules and ions as 21 function

ABSTRACT: An Author's Certificate has been issued for a remote-control cable
linkage for the hydraulic distributor of a tractor-mounted loader having a
hinged arm atop a king post. The distributor levers are rigidly fixed to the ends
of the cables, which pass around the blocks located on the distributor support and
through lead-ins having adjustable tension screws. The cables leading to the con-
trol pedestal are sheathed in flexible sleeves fastened to the rotary disks of the
control-pedestal levers. This design improves the! control maneuverability of the
loader on'various cab-type tractors. Orig. art. has: 2 figures.

Abstract:: This is a survey of the relation of the structure of alkali
earth metal carbonates (used as a ba3C in preparing the emiss-
ive capabilities of oxide cathodes dependinr,~ on them) to the
temperature of precipitation of carbonates and to the concen-
tration of initial salts, the composition of components being
fixed at a given percentage. It was discovered that the most
regular crystalline structure of mixad carbonates (Ba, Sr.)
and the highest emissive capacity in.electronic tubes are
found in the composition of double-carbonates of 50:50 11301.
and at the precipitation temperature, of 920. The best con-

M'L"VT: The process of activation of an oxide cathode depends consi-
derably on the composition and concentration of the binder used in
preparing the carbonate paste. In connection with this, a com-para-
tive investigation of -the decomposition process of carbonate pastes
with various binders has been carried out. 'The method of investiga-
tion was based on measuring the total pressure of the gases evolved
in the heating process of the paste as a function of temperature;
this measurement enables one t6 observe -the chemical processes
occurrin5 in the paste under high-vacuum conditions at high tempe-
ratures kthe decomposition of the binder and of carbonates of alka-
line-earth metals). Two types of binders were investigated, one
based on nitrocellulose and the other baEied, on polymers of methyl

acrylate with various -types of solvents. The results of the investi-
gation are shovin in the form of decomposition curves both of the
binders -themselves and of the emission pastes deposited on cat-hode
bases of various design (a sarong type and a lamellar cathode). The
data obtained show that binders vith methyl acrylate decompose at
higher temperatures. The analysis of the curves enables one to es-
tablish a critical temperature and an optinum rate of temperature in-
crease for a given pum ing speed..3 references. (Przemyslovty Inst.

TITLEt Hardener f or the Foundry Production Based on Synthetic
Carbamide Resins (Krepiteli na osnove sintetichesklkh karbarai-

PERIODICAL: Xhimicheskaya Promyshlennost', *1958, Nr 3, pp 27-29 (USSR)
ABSTRACT t In order to remove the disadvantages of the hardeners on the
bjasis of urea formaldehyde resins as used hitherto, a mixture
with a concentrate of a sulfite-alcohol elutriating was worked
out in the NIIPM in co-operation with the TsNIITmash, with
condensation experiments at different pH values. It was observed
that the condensation is to take place at PH - 7-5 - 8.5. An
optimum recipe is given as well as the preparation technique
and an analysis table. A variation in the duration of the oon-
densation of this hardener (NSB) showed only a remarkable ef-
fect on the viscosity.
The experiments on the effect of low
0
temperatures -3o , -35 showed that at a restoration of the
room temperature a liqu6faction of the hsxdener takes place
again. Physico-mechanical toots) which were madej in the TONIIT-

Carbamide Resins
ferent machine building plants proved that the hardener MSB
shows some advantages cumpared to the oil hardener 4 GU as used
hitherto. A consumption of oil &nd technical fats is avoided,
the drying is accelerated by 25-40% &nd reduced to a temperatu-
re of 30-400, and thus the romoval of the cores is simplified~
On the other hand the production of the NSB hardener is more
simple and cheaper than that of the earl:br developed W, its
stability being inferJw by 40-5o%. There are 5 tables, and 3
