,fUSTRACT: The endurance limit f0 breakage of glued reinforced
concrete joints is about 50 kg/cmi, for a cycle amplitude of
0. 5.
In the elastic stage of operation, the bent elements tuith-
stand 2 million cycles, while in the crack forming/stpe fcr
0.4, the endurance limit of the joint is 45 kg cm
The endurance limit of a glued joint may be raised by J-mprov-
ing the properties of the cement, using "internal" plasticIzers
(polyesters, thiokol).
in prolonged loading, the glued joints show creep that is a
factor of l.b - 2 less than the creep of concrete with an age of
one year, and is attenuating in nature.
In structures that are bent, the creep of the glue produces
redistribution of the internal stresses, and a reduction in rigid-
ity of the beam by a factor of 1.6. Orig. art. has: 7 figurasand2

ABSTRACT: The authors describe a multichannel system capable of
reliably handling
the -Ignal from the approximately five hundred channels of the
Tskhra-tskaro ioniza-
tion calorimeter. To increase the reliability.. the number of
vacuum tubes has been
reduced to a minimum of three per channel, which is
approximately half that used in
similar installations. Each channel consists of a preamplifier,
final amplifier,
gating circuit, and magnetic memory, All ebannels feed into a
common commutator and
regulating unit. 7he remaining circuit elements are transistors
and magnetic core
devices. Zie magnetic core devices are used in the memory. A
block diagram of the
system and detailed descriptions of the preamplifier, final
amplifier, gating circuitfi
and memory cells are given. Origs art. has; 5 figures and 1

ABSTRACT: Surprisingly little attention has been paid to
selection of the air gap length in d.c. machines. The
object of this article is to analyse the influence of
the air gap length on the main properties of the d.c.
machine to review the existing recommendations of
various authors and to suggest criteria for selection of
the air gap length and-"termination of its best value.
Recommended air gap lengths for machines without
compensating windings are first considered, starting
with Arnold's recommendation designed to ensure
satisfactory commutation. Formula (2) given by Richter
and others is used in the Elektrosila works, values of
card 1/4 the factor k are given in Table 1. Three other

recommendations are also given. Recommendations for
ii~,chinees with compensating windings are t-hen given
Particularly that of Kaslyanov, see Eq (6). Values
of k in formula (2), recommended by various authors and
used in actual machines are compared in Table 1, -"
values of k, the air gap length and numerous othE ata
for a number of motors manufactured by Elektrosila and
also for the Siemens GM series are given in Tables 2, 3
and 4. It is shown that some of the formulae give air
gap lengths very different from those actually used and
that none of the authorz takes into account all the
factors that should be considered in selecting the
length of air gap. Properties of a direct current machine
that depend on the length of the air gap are then
considered in turn, particularly: the weight of the
field winding; the stray losses of the pole-piece
surfaces; the amplification factor of the machine;
the time constant of the machine; the noise; the
Card 2/4 speed and critical speed of the motor; and the
greatest

output that can be obtained from a machine of a given
diameter. Certain criteria go-7eraing the best choice
of air gap length for machines with compensatinG windings
are then given. Bq (21) is obtained for the test air gap
length determined from the criterion of minimum losses
on excitation and on the pole piece surfaces. Eq (22) is
obtained for the best air gap length fi-om -.onsiderations
of overall costs. It'is concluded that for machines
without compensating windings the air gap length is best
selected by appropriate choice of the factor 'K- in Eq (2).
To a first approximation the value may be selected
from Tables (1) and (2) but it is necessary to check
that the voltage between neighbourinE; r-,omm-utator bars
is not too Great. The method of doing this is briefly
explained. For machines with compensating,- %?.,indings it
is recommended to use Kas~yanov-s fcrmula (6) and' to
check it against the expressions for mini-mum loss and
minimum overall cost. For high speed machines with
relat.-'Lvely high losses on the pole piece Surfaces, it is
I.ard 3/4 advisable to use formula 21) deri-lied for the
least cost.

In using this formula it should be cuhecked that the
a~eduction in the losses is great enouch and that it does
not lead to excessive increase in size and weiChtu of
the machine. Numerical examples of calculation of
optimum air gap length are given in an appendix~
There are 2 figures, 4 tables and 11 references, 8 of
which are Soviet and 3 German.

ABSTRACT:
The author presents a
classification of different in-

dividual excitation systems of
synchronous generators.

He compares these excitation systems
with the central-

ized excitation which was used in the USSR
only for the

Volkhovskaya and the Nizhnesvirskaya GES.. The
author

describes briefly the different individual excitation

systems and presents a mimynary in a table, There are

three
main categories. A) The independent excitation

systems are
divided into two groups. These are genera-

tors having a) no
exciter or excitation winding, using

permanent magnets instead,
b) shaft-mounted exciters

with excitation windings. The latter
are divided into

two sub-groups, having stator excitation
(induction

SOV/143-58-10-10/24
Individual Excitation Systems of Synchronous Generators
in direct, indirect and compound excitation. B) The
self-excitation system consist in a) generators using
rectified stator current (mercury or disk-type recti-
fiers) and b) generators having a separate stator wind-
ing for excitation using mechanical rectifiers. C) Ex-
citation systems fed 'from buses are classified in
three groups, having excitation winaings in a) the ro-
tor, b the stator, or c) having no excitation wind-
ings at all (special synchronous motors, capacitance
mo-lUors, etc). The author expresses his gratitude to
the honored. scientist R.A. Lyuter for his statement *s
concerning the table of excitation systems. There
are 5 circuit diagrams, 1 table and 21 references, 15
of which are Soviet, 1 English, 3 German and 2 Polish,

ABSTRACT:
The author proposes a method which wil"L perm i h e

laying of concrete under the severe conditions of a

Siberian
winter. The concrete hydraulic structures

to be built are
divided into sections; in summer the

concrete is laid in
alternating sections: for irisran(e

1-3-5- etc. In winter, the
sections 2-4 are la-'d

with the help of insulating shields.
The completed

sections also serve to a certain de 'gree as
shields.

The author also describes different types o.f
"rillies

and concrete-carrying trucks to be used in sumnier

and
winter. He stresses the necessity for Sov~.ef

industry to
construct a highly maneuverable and mo-

bile concrete-laying
truck. There are 2 sets cf d:a-

ABSTRACT:
The efficiency of operation of multi-cell flotation

machines for coal is discussed. A large yield of

concentrate
during flotation of coals causes a sharp

decrease in the
volume of pulp moving along a multi-

cell flotation machine
which leads to an increase in the

time of flotation in the
tail cells. In order to obtain

the same flotation time in all
cells, it is necessary to

decrease the volume of tail cells
(eq.6). This, however,

will not correspond to optimum
flotation conditions,

as a longer time is required for the
treatment of grains

in tailings which are difficult to float.
At the same

time, the duration of flotation in the tail cells
of an

industrial flotation machine with cells of equal volume

is too long. The experimental data obtained on a

laboratory
flotation machine with variable volume of the

cell, indicated
that optimum conditions are somewhere

between the above two
sets of extreme values. Methods of

increasing the output of
flotation machines discussed in

On increasing the output of flotation machines on
coal
washerieB. (Cont.) 156
the paper possess one common feature - a decrease
of the
flotation time in tail cells. The most promising
method
appears to be an additional supply of tail cells
with
the starting pulp and the organisation of flotation
according to scheme shown in Pig.4. It is stated in
the editorial remarks that in view of the
propositions
made by the authors further discussion on the
subject
is invited. There are 4 tables, 4 diagrams and 8
Russian references.

A13STRACT: It is shown that the methods at present
available for the determi-
nation of the order of the velocity of irreversible
reactions for
equivalent quantities of reaoting substances do not make it
possible,
basing upon the data obtained by an experiment, to compute
the values
for the order of velocity with sufficient accuracy. Here a
grapho-
analytical method for such a computation is suggested. It
is based
upon the experimental data on the modification of the
concentration
of reacting substances in an experiment, and is illustrated
by means
of three examples of amputation. There is I figure and I
table.
