TinE: One possibility for construction of digital analog functional convertert;
SOURCE: Avtometriya,no. 2p 1966, 90-98
TOPIC TAGS: digital analog converter, circuit design, mathematic analysis
ABSTRACT: A method is described for the construction of digital-analog functional
converters based on preliminary expansion of the function into a series by Walsh
functions. It is shown that the elements of the digital-analog converter are in-
terpreted easily by the category of this expansion. Examples are presented of the
realization of some digital-analog functional converters. The limitations within
which the application of this method will give a gain in comparison with known methods:
are determined. The advantages of converters constructed using Walsh function ex-
pansion are simplicity of the analog portion of the circuit and the constant output
impedance of the analog portion of the circuit, which allows them to be used with any
load without disrupting the nature of the dependence reproduced. Orig. art. has:
2 tables, 7 formulas, and 4 figures.

IABSTRACT: A generalized analog--to-digital converter model was developed which is ap-
plicable to the analysis of a large class of such converters. The model was analyzed
by congruence of the sets of components; it was assumed that quantization and numeric
coding of the measured values occur during the measurement process. Four major sets 0
parameters which quantitatively define the developed simulator model are defined; one
,of the parameters simultaneously defines the number of scale graduations of the analog
and the number of lines of the matrix, and thu3 the number of states of the model. The
developed concepts of structural and functional evaluation of simulator models can be
used in the quantitative evaluation of the complexit-I of various classes of analog-to-
-digital converters. The authors thank Doctor of technical sciences M. P. Tsapenk

TITLEt Slip bearings of AST-T plastic and of its compositions
SOU110; Vestnik mashinostroyeniya, no.~1967, 45-47
TOPTC TAGS: bearing material, antifriction, bearing, wear resistance, friction
coefficient, plastic, bronze/ AST-T plastic, Br. OTBS 6-6-3 bronze
ABSTRACT: The results of tests of slip bearings with bushings of AST-IL plastic are
discussed. The bearings operated in oil on a test bench with three working friction
sections. The AST-T plastic contained fillers of S-1 colloidal graphite, barium
sulfate, zinc oxide, and tale. For comparison, bushings of Br. OTsS 6-6-3 bronze werel
also studied. It was found that increasing the filler content above 5--lw- caused 1,
practically no improvement in the antifriction properties of the bushings (see Fig. 1)i
The wear resistance and bearing capacity of the AST-T bearings applie?l to the GA-301
pump were tested. The resistance of AST-T was found to be 1.64 times greater than
that of capron. After 1200 hrs of operation in oil, the bearing capacity of the AST-Ti
bearings was no less than that of the capron and bronze ones.

TITLEs Organization of Preflight Medical Checkup of Airplane Crews
PERIODICALs Voyenno-meditsinskiy zhurnal, 1960, No. 4, PP- 72-73
TEXTs The author states that a number of pilots, when jointly questioned
about their state of health, were reluctant to speak frankly. Therefore,
checkup rooms were specially equipped for ambulatory examination in
which each pilot is individually examined. The preflight checkup begins
in the mess-room where the surgeon studies the appetite and behavior of
the pilots. In the examination room, the emotional state of the pilot,
his integument, and the visible mucosae are examined, the pulse Is
checked and the pilot subjected to an examination in the Romberg position.
The results are entered in a so-called preflight log. After the flight.~
the pilot has to undergo an examination of the same kind. A comparison
of the results obtained before and after the flight decides whether the
pilot is admitted to the next flight. On the basis of the preflight

checkup, 0.8% of the pilots were found to be unfit. Fifty percent of
these pilots suffered from diagnosed indispositions, one-third complained
of their state of health spontaneously$ the rest had simply disregarded
preflight regulations. These control measures help the medical officer
to prevent flight accidents.

TEXT: The author presents the solution of J. Tompson!s problem on ionized
gas between electrodes. Not only positive and negative ions are taken into ac-
count but also electrons. If the current is far from being saturated,, the space
between the electrodes can be divided into the following regions: anode, central
and cathode region. The integration of Poisson equations and balance of charged
particles shows that field intensity and potential at the cathode are always
higher than at the anode. Electron losses due to formation of negative ions may
lead to a considerable charge of the field.

Thermal Dissociation of Ammonium Molybdates
The thermal disoociation of ammonium molybdates was carried out
by the thermographic and thermogravimetric method, together
with the chemical analysis of the intermediate products. The
course of dissociation of various ammonium molybdates can be
carried out according to the following scheme:

SOV/78-3-1 0-1 0/j/35
The thermograms of various ammonium molybdates are presented
in the figures (1) and (2). Thus it is demonstrated that normal
molybdates, as well as paramolybdates, lose ammonia or water
at above 1500C when they are thermally treated. Above this
temperature all dissociation products have the same composition.
The final product of dissociated ammonium molybdates is amorphous
MOO3 that is formed at 3500C and assumes crystalline form a.
400-4200C. The results obtained are different from t0hose mention-
ed in references. There are 2 figures, I table, and 4 references,
0 of which is Soviet.

ABSTRACT: At present only a few theoretically and practically founded
absolute methods for the determination of the molecular
weights of polymers are known, none of them, however, may
be called universal. The determination of the molecular
weights within the interval from 1000 to 50 000 represents
the difficult range of determination. In view of the great
possibilities of the employment of the icopiestic method the
present article gives an investigation of various varieties
of this method as well as the moat important experimental
data. The author deals with the idea of the isopiestic method
based on the investigations made by Errer, The author di2-
cusses in detail the investigations carried out by Berger
as well as the method he employed. Then he discuases the

varieties o' the capillary filling, He mnkec a special i-efer-
ence of those by Niederl and Levy (Eiderlt and Levi) (Ref 7).
The papers -,,iritten by Niederl and Kasanof (Kazanov, Refs 8, 12),
Pavlova and Tverdokhlebova (Ref 9), R. Wright and Nieuwen-
burg (Nivtxxher1-, Refs 13; 14) are also mentioned and discussed.
Those naptl-~-s deal with an ingenious modifi.catior. of the
Berger method (important increase of the rate of vapor dif-
fusion) by which a reduction of the time required for the
determinalion of the molecular weight of the' polymer is
achieved~ The author discusses the Wright apparatus, the
microisoDiettic method according tc Karl Schwarz (Shvarts,
Ref 15). The Schwarz method requires the determination of the
equilibrium concentrations in two solutions in the vapor
phase and at constant temperature. The macro method employed
by other authors is discussed in short (Refs 16, 17). Finally
the author mentions the method suggested by Singer (Zinger,
Ref 18) and the apparatus constructed by the latter Is dealt

ABSTRACT: At present micro- and macro-methoda exist in this technique,
the principle of which was for the first time proposed by Berger
(Ref 1). The method by Signer (Ref 6) must be mentioned in
particular. In the present study n-dibromobenzene, azobenzene
and 1,2o-eicosandiol benzoate are used as standards. Some modi-
fications of the methods applied hitherto for the purpose of
precising the measuring technique wereperformed. Containers, a
figure of which is given, and the weighing method according to
MazBen were employed. The somewhat modified micro-method of
determination according to Barger-Rast (Refs 2,5) was found to
be the most accurate and most convenient one. The experimental
technique employed is described. It appears that a mixing of
Card 1/3 the two solutions is almost impossible, thus an increase in the

accuracy of determination being achieved. The temperature of the
thermostat must not exceed the boiling temperature of the solvent
employed. The size of the drops is measured on a 14)A-2 comparato
with an accuracy of 1p. Experiments were conducted -co establish
the degree of accuracy of the method. The results are given in
a table. Froin it satisfactory results for substances with a
molecular weight of up to 17000 may be seen. The method is
applicable to molecular weights of UP to 50000. Finally thanks
are expressed to G.L.Slonimskiy. There are 6 figures, 6 tables,
and 18 references, 0 of which are Soviet.

TEXT: The authors studied the solutions of polydimethyl siloxane in
chloro benzene and benzene at 20, 30, and 400C, and in isooctane at 20 and
300C applying the method of viscous flow, light scattering, sedimentation
by ultracentrifugation, and diffusion. Fractional precipitation of poly-
dimethyl siloxane with methanol from its 3~o solution in benzene at 200C
yielded six fractions, the molecular weight of which was determined by
light scattering. The results are given in Table 1. The viscosity of the
polydimethyl siloxane solutions in chloro benzene at 20, 30, and 400C is
represented graphically in Fig. 1. The molecular weight of polydimethyl
siloxane was calculated from the relation

where S - sedimentation constant, D - diffusion coefficient, R = gas con-
stant, T - temperature in 1K, v - specific partial volume of the polydi-
methyl siloxane and 9 = its density. The viscosity of polydimethyl siloxane
solutions in chloro benzene, benzene and isooctane at 20, 30, and 400C
are shown graphically in Figs. 2 and 3. The viscosity of polydimethyl V/\
siloxane solutions in chloro benzene at 20 and 400C and benzene at 201C is
a linear function of the concentration. By determining the viscosity and
molecular weight, the authors obtained the constants K and a of the
equation Gq] = KMa' which gives the relation between the intrinsic viscosity
and the molecular weight. In Fig. 4, 109111 is plotted against log M for
polydimethyl siloxane in chloro benzene and benzene. The dependence of
log K on a, as calculated from the general formula

listed in Table 3. The mean distance between the chain ends is described by
the relation (-~2)1/2 1/2. Fig. 6 represents the function
1/2 ' 1/2 0
(V) - f(M) for chloro benzene solutions of polydimethyl siloxane at
20, 30, and 40OC- From this it follows that the root mean square distances
between the chain ends of polydimethyl siloxane in chloro benzene and
benzene increase with an increase in temperature. The constant A, which
designates the ratio of the hydrodynamic diffusion and viscosity radii of
ma6romole cules, was calculated from the relation
A =/QOT- 1D(M[tj)113, where% is the viscosity of the solvent in'poise, T
the temperature in OX, D the diffusion coefficient, M the molecular weight
of the polymer and UV the intrinsic viscosity. In the case of the chloro
benzene solutions of polydimethyl siloxane, A changes little with tempera-
ture variation, i.e.' by 2.27-10- 10 to 2.8.10- 10 erg/degree. The relation
between the diffusion coefficient,*D, and the molecular weight of the poly-
mer, M, was calculated and expressed as D - 1.05-10- 4M-0.547.

,ABSTRACT: Polyphenylsiloxanes obtained by condensation of the hydrolysis products of
plienyltriclilorosilane in four solvents (benzene, toluene, xylene and dinil) were investigated
by infra-red spectroscopy. All four polyphenylsiloxanes were found to have the same cyclo-
linear structure predicted by Brown, et al. (J. Amer. Chem. Soc., 82, 6194, 1960).
The molecular weight of the polymer was 4. 1 x 106. Ilie effect of tho reaction medium on
the mechanical properties, the degree of polymolecularity and the structural homogeneity
of polyphenylsiloxanes was studied in detail. The four test samples were fractionated from
0. 5% benzene solution with methanol at 20C. Infrared spectra were then taken for all four
polymers, their thermal properties were studied and the molecular weight was determined
by light diffusion. The molecular weight distribution curves are plotted. The polymers
wer.e found to be rather stable during fractionation. The infrared spectra show that the
