Abstract: On the basis of bacteriologic studies involving
septic and aseptic operating rooms, dressing rooms and patientep
as well as a detailed investigation of specific cases of infective
complications acquired in the course of hospitalization (2 case
histories are presented), the authors evolved some administrative
measures aiWd-'at; the prevention of such infections. The mea-
sures relate to administration of the hospital generally and to
the disinfection of patients and doctors.

TITLE: Molecular generators
PERIODICAL: TelecomunicaVii, no. 2, 1960, 71-78
TEXT: The performance of molecular generators is analyzed
by examining the phenomena upon which it is based and of the prob-
lems concerned with this mode of generation. The definition for
these generators ("Masers") is given, discussing first the problem
of rctalizing energy level values to permit transition frequencies
in the radio range, and showing that realization of high transition
?robabilities, finding new methods for enrichment of the higher
level and the use of suitable substances are the main problems con-
nected with developing these generators. TheoreLical coasidera-
Lions are then i)resented for realizing electronic transitions at
radioelectric frequencies, 300,000 - 3,000 hc/s, the necessary tran-
sitions bting between levels at distances in the range 0.001

0.00001 eV, and formulae are presented for calculating spontaneous
and radiation stimulated emissions. It is further shown that the
probability of atom excitation in the presence of an exterior radi-
ation-, is a sinusoidal function of time, that it is necessary to
have a larger number of excited molecules (at the moment when the
exterior field is applied) than is the number of normal molecules,
and that the e-xtarior field of a frequency equal to the transition
frequency should be applied during half a node of the probability
cullve. Molecular generators employing the ammonia molecules beam
are then considered, describing the method of sorting the molecules
in order to separate the excited molecules which are introduced
into the cavity. The dimensions of the cylindrical cavity a-Lid the
perfori-fiance of the resulting oscillator are reported. A descrip-
tion. of the principles of solid-body masers follows, considering
thiE the c haracteri sties of two- energy- levels generators, consist-
ing of crystals spiked with foreign donor atoms. The three succes-
sive phases of the performance of this type of generator are des-
cribed., Finally, three -energy-levels generators, with three dis-

ing the fundamental principles concerned. Performance data on gen-
erators of this type, employing gadolinium ethyl sulphate in a lan-
thanum salt and potassium cobaltocyanide with 0.57* chromium, is re-
ported briefly, discussing the advantages and disadvantages. The
apAication of the various types of molecular reenerators is then

scussed, mentioniq the use of their main characteristic - the
possibility of creating conditions vrithin it Which permit a maximum
variation of the spectral line frequency of 10 , and stressing its
main error - the accuracy of the generator frequency determination,
depending on the precision of the resonator accord on the spectral
line frequency. A molecular generator irith special performance is
described subsequently (as constructed by 1,4G. Basov and collabora-
tors at the 'qA-bedov" Physics Institute AS USSR) Z-Abstracter's note:

on the stimulated radiation of an excited system of atoms, ions
or molecules. The amplification may be produced by two or three
energy levels of varying population density. Kilcuchi, Makhov
and Terkhune studied the problem of a maser with four levels
using a ruby. According to the location of the maser's active
material, the solid state amplifiers are divided into travel-

ling wave amplifiers and resonant cavity amplifiers. Travel-
ling wave masers with a 20 Me band can be tuned between 200
and 500 Me in a frequency range 000 Me. The most suit-

able substances to be used as active materials are gadolinium.
ethylsulfate; potassium chromicyanide; and ruby. Gadolinium
ethylsulfate was the substance used.in the first solid state
amplifier made by Scovil, Feher, and Zaidel. Potassium chromi-
cyanide is diluted in a cobalticyanide crystal EK Co (CN)63,
while 0.5% Cr are used as paramagnetic salt. Mc~Rorter and
Meyer calculated the energy levels for potassium chromicyanide
diluted in cobalticyanide crystal. Because of the low output
power of the studied amplifiers, scientists have tried to in-
crease the efficient coupling between the maser material and
the microwave field. One of the means tried is the use of a
retarding structure of the phase, in order to obtain a rela-
tively long time of the reciprocal action between the signal
and the maser's material. Active molecules may be obtained

by the method of deviating the molecular beams in a non-homo-
geneous continuous,electric or magnetic field; the method of
the auxiliary high-frequency field; the method of optical pump-
ing; and, the method using the Stark square effect. The author
then briefly describes a travelling wave maser with gadolinium
.ethylsulfate and.a travelling wave amplifier with a ruby. The
signal frequency of the gadolinium. ethylsulfate maser was 6,000-
6t3OO Me, the feeding frequency 11,700 - 12,600 Me, and the
intensity of the magnetic field Hoil,800 Gauss. The amplifi-
cation obtained was % 30 Mc. The central frequency of the
ruby amplifier was 5,800 Me the tuning range 5 750 - 6,100 Me,
the intensity of the magnetic field 3,930 - 4RO Gauss, and
the feeding frequency 1 goo - 19,500 Me. The amplification
obtained was 23 db. The author finally examines the general
characteristics of molecular amplifiers, such as bandwidth,
stability and background noise, and presents the most impor-
tant.application possibilities of these types of amplifiers.

ABSTRACT: The directives of the XX Congress of the KPSS contained the
following passage: Plans nust be established in due.time
for a more extensive use of radioactive radiation in in-
dustriesq agriculture, and medicine, in particular for the
quality control of materials, for the inspection of production
processes and their automatic control. In recent times such
apparatus have been developed and introduced into industries.
The radioactive level gage UR-4 is widely used in t1ae control
of the level of liquid chlorine in containers in various
production processes. The radioactive level indicator RIU-1
measures the maximum and minimum height of dust in dust
eliminators used in roasting pyrites in the "rimning zone".
The radioactive device PZhR intended fordie measurement of

oil, electrolytic soda, calcium chloride, etc. Special
care must be taken in the use of radioactive apparatus rhAch
operates with gamma-radiationg and the same holds for appa-
ratus using high-energy P-ndiation. 250 of the 500 large in-
dustrial plants in the USA use radioactive isotopes in one
or another form. In 1957 the use of radioactive isotopes
saved 406 million dollars, and this figure will -climb to
5 billion dollars in about 5 years. At present all directions
for use of radioactive apparatus include specifications as
to their installation and operation. If these specifications
are strictly complied with, an irradiation of personnel vith
prohibitively high doses (that is OD5roenteen per working
day) is excluded. In practice, however, it appeared that the
unclear wording of these specifications renders control and
sanitary inspection more difficult. Hence it is necessary
to issue specialized sanitary regulations for the application
of radioactive apparatus with inherent gamma-sources for
technological inspection purposes. According to the opinion
of the authors these regulations should be bases upon the
folloving considerations: In places where people are working
Card 2/4 who are not professionally enga.-ed in work with ionizing

radiation, the radiation dose originating from technological
inspection apparatus should not exceed one tenth of the maxi-
'mum admissible radiation dose. If this requirement is to be
satisfied in practice, it is necessary to keep the dose rate
on the surface of such apparatus below 0.2 microroentgen/second.
The majority of apparatus which is in use at present do not
comply with this standard? and if such "sub-standard" equip-
ment is employed, additional protective measures are required.
Subsequently, formulas for safety clearances are derived and
applied to special cases. The safety clearances can also be
determined with a dosimeter. It appears to be expedient that
the manufacturers of radioactive apparatus should send a team
of specialists to customers who will look after the installa-
tion of the equipment in a suitable place. A report is given
on the problems involved in transporting such equipment and
on its regular inspection. Finally, the authors express their
gratitude to L. N. Balanina, researcher at the Institut
gigiyeny truda i profzabolevaniy (Institute of Labor E~ygiene
and Professional Diseases) for her valuable assistance.

ABSTRACT: This Author's Certificate introduces a radio interference level indicator
based on using reflection of high-frequency electromagnetic oscillations from the sur-
face of the medium to be monitored. The unit contains a high-frequency oscillator
connected through a length of transmission line to a coaxial pickup and a measurement
circuit. Measurement accuracy and reliability are improved by connecting an element
in the transmission line with a reactance which depends on the voltage applied to it,
e. g. a voltage-variible capacitor. This element compensates the electrical length
of the line under the effect of a.voltage proportional to the level being measured.

Abstract Control of underground fires at pyrite deposits can be
effected not only by mechanical but also by chemical
means on utilizing irater soluble substances which pre-
vent oxidation -- antioxidants or inhibitors. Over a
period of 65 days experiments were carried out on tes-
ting various inhibitors: 1) tar water; 2) technical
xylenes; 3) aniline; 4) phenyl hydrazine; 5) furfural;
used in the form of aqueous solutions, and for the sake
of comparison therewith, also of tap water. Operational
procedures and the results are described in detail. It,
vas found that some orgatic substances, such as phenol

and -its derivatives) are inhibitors of oxidation of
polyoulfide ores by atmospheric oxygen. It is shown
that moistening of the ore with a solution of xylenes
or with tar water slows down the process by 13-14 times.
