-ABSTRACT: A unified interchangeable pneumatic! anti electric transducer has been
designed for meatior.ing absolute and gaee pressure, vamum, preopure drop, draft,
temperature, gas and. liquid flow rate, level,. ,denisity, viscosity, mechanical force#
and angular speed.. This trene.ducerg whose sensitivity threshold is 0.05% of
measured range consists of two functional components:'l) a sensor or measuring unfV-
Idifferent-for ead,h-paramter-type)-vhich-conVertzi the measured quantity into-a
proportional forc e',of 0-0.5-0-5 kg; and 2) a staitdard force-to-pneumatic signal
converter which translates sensor output into pneumatic signals (in ~the 0.2-1 kg/cm?-
range at 1.4 kg/cm!2,feeding pressure)., This Mnverter Is used with all types of
sensor; Sensor olx~put force is balanced by. converter -feedback force. A change In p
destroys the equiliLbrium of the system g: vheretqon -a control element actualis the error
indicator to produi:e a pneumatic control signal. After being amplified, the signal'.
pIasses to a remote:. control line and also to the IeWws.. -The latter creatues a new force

TITLE- On the problem of creating a unified system of pick-ups
PERIODICAL;; Priborostroeniye, no. 2, 1962, 3-5
TEM. One of the main problems in developing complex automatic systems
is considered to be that of pick-ups used for conversion of all possible
parameters.into a few physicalquantities, such as displacement, resistanceQ
force, d.e. and a.c. voltages. A large group of parameters to be measured
consists of thaw which act directly on the sensing element of the pick-up
and produce force or displacement, These parameters wou).A include tile
temperatur;e, flow, pressure, Level, r.p,m.,force power2 voltage and current
density. Measurements of these can tie based on a single principle which
would facilitate unification. Analysis of industrial requirementsg carried
out at NliTeplopribor, show that many branches of industry at present
require pick-ups with an accuracy olt 0.5 to I and sensitivities not less

than 0.05 +'O.I%of the measurement range and time constants of 0.1 sec.
or less. Theanalysis of pick-ups and experiments with Soviet- and non-
Soviet pick-ups have shown that the above degree of accuracy can be achieml
only by appILying negative feedback. Negative feedback is used extensively
in pick-ups with force compensation in automatic control systems. NUTep-
lopribor is.now developing a system of interchangeable standardized elec-
tric and pneumatic compensation pick-tips of class 3.5 and 1 for measuring
temperaturet flow,) relative and absolute pressures, pressure drop, vacuum,
traction, liquid level and density. Approval of government standards for
pneumati-c ar;d electric input signals helps the unified instrumentation.
The standardized pick-ups which are under development.at the MtTeplopri-
bor will fuIJy satisfy the principle of modular construction, according to
which all units perform certain pre-determined functional transformation
and are designed according to the modular techniques. The modular method
of standardized pick-up design will permit further improvements and wider
range of applications. There are 2 figures.

ABSTRACT: One of the autbors proposed a hy Ipothesis of the formation

samples of Donets C04LIS for elemental sulphur using the sulphite
method was carried out (a detailed description of the analytical
procedure is given). It was found that both sanples contained
about 0.15% of elemental sulphur. As this sulphur could not
be extracted by carbon tetrachloride, it should be present in
coal in amorphous form. It is concluded that the presence of
the elemental sulphuj~ can be taken as the donfirmation of the
above hypothesis on the formation of pyrites and that in
addition to sulphate, pyritic and organic sulphur in coal,
elemental sulphur sh6uld be included into the classification
of forms of sulphur in coal. There are 2 tables and 12

ABSTRACT: Scientific principles of centrifugal beneficiation of
coals are,discussed., The necessity of the correct choice of
the size to which coal is:crushed is illustrated with examples.
It is pointed out that -the centrifugal method of beneficiation
is based on the 8imultaneous utilisation of the basic principles
,of beneficiation, 3-4:e. rational crushing, true heavy solutions
and a strong centril!ugal field. Therefore, this method is
particularly suitable for the de-sulphurisation and de-ashing
of coals which are fliffieult to beneficiate. Three modifi-
cations of the technological scheme for centrifugal beneficia-
tion are discussed::: Fig-3-- two-product scheme; Fig.4 -
three-product scheme; Fig-5 - a simplified scheme without an
additional cleaning:of the concentrate. Albrief description
of the required equipment - beneficiation., separating and washing
,-centrifuges and automatic filter press for separating the
concentrate and the clarification of thezolution are given.
Characteristics of heavy liquids (Tables 3 and 4) are briefly
Cardl)4scusse d. The operation of the centrifugal method of

beneficiation is illustrated on a number of examples of lab-
oratory and ex erimental-industrial de-sulphurisation of Donets
coals (Table 53, do-ashing of low sulphur coals (Tables 6-8)
and petrographic beneficiation of coals (Table 9). Following
experimental viork 'on the Zhilevsk experimental coal washery,
during which the technoloCy of the process was developed and
themain equipment checked, two new industrial plants at
Bogurayevsk and no-vo-Kondratlyevsk TsOF of 300 000 tons/year
output were designed. The above plants should beneficiate
Donets coal 3-0 rtm of the FS type. Some economic features of
the process are diiacussed. Itis pointed out that the figures
quoted are only approximate. There are 9 tables, 8 figures
and 3 Soviet references.

for recovery and composition of concentrate (and tailings) in

ABSTRACTO~ The authors point out that wet concentration methods,
although more effective than dry methods, have certain
disadvantages. The use of dry heavy media was proposed
in 1926 but the techniques used were not satisfactory.
Work is proceeding at the IGI AN SSSR (IGI AS USSR) on
the use of fluidized beds as heavy media for coal
washing. Experiments with fluidized -0,6 mm magnetite

TEXTs During the last few years a number of investigations on the
application of y and X-rays for the automation of coal
benefi~;iation processes was carried out in the'USSR. As a result,
varioujiIseparators were proposed in which the dependence of the
degree of absorption of rays on the content of.mineral
admixtures in coal was utilized. The scheme proposed suffered
from A limitation caused by the influence of differences in the
particle size on the degree of absorption. In the paper two
schemes of compensating the degree of absorption of rays for the
thickness of coal particles are outlined. The two-rays scheme
(Fig.1) is based on the utilization of differences in the degree
of absorption of y or X-rays of a low and medium power by a piece

coal and their intensities measured, then a mathematical
treatment of the data obtained permits,determining mass
coefficients -of -ab-sorption -of -the rays -used.- --A single ray
method (Fig.2) 'is based on-the application of an electromechanical
corrector with a moving probe. The position of the probe is
determined by the size of the coal pieces passing under it. The
probe Is connected with an apparatus regulating any electrical
value (resistance, capacity, inductivity etc); this apparatus is
incorporated into the measuring system and compensates for the
non-uniformity of coal pieces. There are 3 figures and 2 Soviet
.references.

ABSTRACT: An Author Certiftcatchas been lssu~d for a device for studying elastic
audib, Wilich Includes a transparent shaft and a device for fastening the test parts
onto 'it. To Study the'belia-4ior of the elastic-seal surface in contact with the shaft,
~the shaft is made hollow, with'a conical inner surface (coaxial with its outer our-
face),.and contains a light sources In order to record the behavior of the elastic-
seal,surface in contact with the ahaftj it is equipped with a motion-picture cameras
