Title Changes in the Fractions of Horse Serum when Immunized Against
MaUgnant Anthrax.
Orig Pub Acta veterin. Acad. sci. hung. 1957, 7, No 1, 95-98,
Abstract A prolonged immunization of horses was made by agar culture
of incapsulated bacillus of malignant anthrax (Pasteur Strain
II). The culture was first injected subcutaneously, and later
intraveneously and. subcutaneously at the same time. Inves-
tigations made by electrophoresis on starch) of 5 serums, prior
to immunization, after subcutaneous injections (after 6 weeks)
and as long as the immunization course lasted, revealed: (a
corresponding) decrease of the albumen level: plus alpha-globulin
from 52.73 to 33-36 and 31-66 percent; of alpha 2 globulin
from '12.8.to 4.73 and 3.28 percent; an increase in the content
of beta-globulins from 17.5 to 39.23 and 24.2 percent; and of

ABSTRACT., The work of V. 1. Foodoslyev (Izbrann5rre zadachi i voprosy po
soprotivleniyu materialov. Gostehh-toorizdat, 1953) on the critical velocity of flow
in fluid pipes (lateral instability) is extended to the case of axially restrained
pipes, --TEi;-eecases are considered: a) the left end is fixed and the right and is
free in the axial direction (flow to the right); b) the left end free and right end
fixed; and c) both ends fixed. The equation for the unbalanced loaded pipe is for-
-mulated in integral form, and the solution is found in the form of a series. The
,,,,equations for the critical velocities for cases,a and b are found as

,respectively, while no simple solution for case ccould be found. Curves of the
ratio of frictional to inertial forces as a function of Reynolds number re pre-
sented for various pipe diameters, and it is found that for Re 10 - 10t
the ratios
are higher or near 1. It isconcluded that.fluid frictiorVIis of major importance
in pipe stability and that pipe restraint. of' typo a reduced the danger of pipe

A BSTRACT: The types of steel mentioned in the-title were investigated., 1:,
They were made In form of tape rolls (0-03-0-35 mm thick.and,
o-rer). Under equal processing conditions, the degree of the
~Ompleteriess of texture is not the same for different charges
and must therefore be determined besides the magnetic proper-
t-es. The domest.ic industry unfortunately does not manufacture
a suitable andsoineter. At the'Leningradskiy staleprokatnyy
zave)d (Leningrad steel Rolling Mill) the tempering of the
samules is carried out jointly with the tape rolls so that "he
properties of It-he sam-Dles should correspond to those of the
metal strips. For samples of thin metal strips (0.03-0.2 mm),
bands i.5-2.5 m long were cut off and wound or, a template

toluene were used as insulation betiveen the windings. Strips
of transformer steel (0-35-0.5 mm t2ndck) were also made in
form of rolls The samples were pre-.-:)ared as packs or - as
mentioned above - as toroids. The dqtermination of the specific
Losses and of the induction of thes:a strips are best carried
cut with large and small Epsteints devices at frequencie Is of
50 and 400 cycles per second; the'induction measurements should
be made in tension fields of 0.001 to 5 oersted with 'toroidal
samples. The calculation of the tension of the field is car-
ried out according to a known equation.

quantity of oilA the rings are so turned in respect to one another that in each
pair the opening of one is diaistrally opposite to the o7paning in the other. The
openings in the innerrings of the adjacent pairs are turned at an angle to one
another.' The size of this angle in compated by the formla 3600/n, where n Is the

Tables 2
Dried live polyvatent. influenza vaccine was used for Intranasal vaccination of
8.839 persons in 7 industrial centres. 2,934 unvaccinated persons served as a con-
trol group. The vaccination reduced the attack rate of influenza and upper respir-
atory tract catarrhs by a factor of 1.8 and the duration of the Illneas by 0.2 day on
the average. Analysis ofthe data indicated that vaccination was more effective in
groups with a high attack rate provided that inoculations were carried out before
the rise of the incidence. Vaccination of groups exposed to unfavourable meteoro-
logical factors proved to be Ineffective. (IV, 17)

perimental investigations of weighing and testing machines. The investiga,
tions were conducted by the Nauchno-issledovateliskly institut vesov I

articles deal with analysis of errors in dial-type automatically balanced
indicators and methods for designing indicator elementsY experimental inves-
tigato of elastic imperfections in springs used for measuring forces, anal-
ysis of accuracj In dynamic-load measurement with hiah-frequency fatigue-
testing machines, and the relation between the error of measurement of cyclic
reversed loads and the degree of damping of oscillations of an elastic element.
A-1so discussed are measurement of the acmu-acy of forces in a water tunnel and
a method of checkingindicators of hyx1ralLUcally actuated fatigue-testing
machines. References follow several of the articles.

PERIODICAL: Novosti neft. tekhn. Neftepererabotka, 1957, Nr 7, pp 21-Z4
ABSTRACT: Soviet consta.nt-drop rotametric flowmeters with movable resistance.-
can be subdivided into two groups: (1) low-pressure, up to 6 kg/cmz ; (2) high-
pressure, 10-100 kg/CM2. Each group can be subdivided into indicating,
recording, and regLdating instruments. Designs of some rotameters are,
discussed. The electric follow-up system is replaced by a permanent magnet
system in the rotameter described in the article. The essence of the.magne.tic
system is that a permanent magnet carried by the rotor causes a. diSDIacement
of two external magnets whIch move the indicating pointer in the direct-reading

strument. For remote measuring, the instrument is equipped

ABSTRACT: The characteristics of a photoelectric c
control and measuring circuits are described. The four-terminal con.-
verter consists of an SFZ-2 phocoresistor (output terminal pair) en-
closed in a capsule together with an NSM-type low-voltage incandescent
lamp which operates at either 6v, 20 mamp, or 9v, 60 mamp (input terminal
pair). The converter is characterized by a slight temperature dependence,t
absence of galvanic coupling between the controlling and the controlled
loop, a relatively low time constant, and a high linearity. Some char-
acteristics of the converter are: input impedance, 200-400 and 80
170 ohm for 6.3-v, 20-mamp and 9-v, 60-mamp NSM lamps; maximum transfer
factor, about 10; temperature instability at an ambient temperature of
1000K is

with 9-v. 60-mamp lamps); maximum input power, 20-40 mw. orig. art. has:,

ABSTRACT: The Designing Bureau for Automation of Oil Refineries has de-
veloped tension manometers ("tensomanometr" ) and differential
tension manometers (-Itensodifmanometr") provided with wire
resistance-indicators, for measuring and controlling pressures
in various technological devices. The article gives a detail-
ed descriDtion of the design of tension manometers for 100,
300, and ~00 kg/cm2, comprising different numbers of wire in-
dicators (for various-degrees of accuracy), and differential
manometers for the same range of static pressuresand pressure
drops of 5-20-40-80 kg/cm2. General pri=iples of designing
and choosing materials for resilient instrument parts for work
in corrosive medium and under varying load are discussed.
Welding of these instruments is not recommended as well as
galvanizing with copper, nickel and chromium, as such coating
reduces corrosion-fatigue resistance. Steel grades suitable
for work conditions concerned are recommended.
The article contains 3 drawings and 1 diagram.
