ABSTRACT: The cathode had a disk-shaped edge with a large emission
surface in comparison with a point, the emission edge being examined
with a BS-242 electron microscope. A description is given of the
instruments used to study the field emission current and the emission
pattern of the tungsten edge. The results showed that under con-
tinuous and pulsed conditions, the current from the cold edge was
50 mamp (v, - 13 kv). and 2 amp (v - 20 kv) , respectively. Volt-ampere
characteristics for two values of edge curvature radii, and curves
,of current distribution along the edge under various anode voltages$
indicated that emission was stable under small voltages, while higher

OPIC TAGS: laser, ruby laser, laser output frequency, laser frequency variation,
ABSTRACT: A method is described for converting the output frequency of a laser by
using the Raman lines of the beam in benzene and its subsequent mixing in an ADP
cr-
ystal. The arrangement consists of a Q-switched ruby laser (the output beam of
which is passed through a vessel 'with benzene), the mixing crystal, a filter of
aqueous s8lution of CUSO4 (for suppression of the main frequency of the laser at
X = 69h3 A), and a PGS-2 spectrograph With photographic recording. The Intensity of
Raman lines (A = 641s, 71,59, and 8059 A) is sufficient to effect a nonlinear interac-
tion of a;l frequencies within the 2-mm thick mixing crystal. The emissions at 3471
and 3729 A can be considered second harmonics or the results of the mixing of
corresponding frequencies, while those at 3596 and 3814 9 are the results of mixing
'8.
ACC NRi AP603-29jJO
cii ly .Tne intensity of these line-, can be explained by a large diverge-nce of the
focused beam, which insures that the conditions of synohrLtiism are fulfilled for all
frequencies. The experiments show that by employing Raman scattering in various
substiffices with subsequent nonlinear transformation in an ADP-type crystal, a cohere
output beam can be obtained at any frequency within the optical range. Orig. art.

ABSTRACT: Theoretical and experimental investigations were made of the variation
A~o affecting the phase-matching angle *, for second harmonic generation
.(SHG) in an ADP crystal whose optical characteristics are modified by an
applied electric field. It was found that only the component E. of the
field along the optical axis has an appreciable effect on the angle *0.
This effect is at its maximum when the plane of the laser beam in the
crystal and the optical axis is at 45* to the transverse crystal axes.

appreciable only in the immediate vicinity of *,. The beam generaeor
was.a 12 x 120 mm ruby laser, which operated in 500-700-14sec single
pulses. Oscillograms of the SHG are given. Numerical results for field.
values of 45 and 90 kv/cm are in satisfactory agreement with the theory.1
The authors suggest that the described effect can be used for making
accurate measurements of nonlinear constants of materials and accurate
adjustments of the index-matching angle in the case of.displacement and
parametric amplification of optical frequencies. The authoro thank

the theoretical frequencies by means of the Gaussian law and
the criterium of agreement was determined, according to which
the straggling of test results were found to obey the normal
distribution law, which was also graphically confirmed
(Pigs a,b) by the agreement of results with those obtained by
Barwell (Ref 1) and Scott (Rof 5). The diagram of the probabili-
ty distribution may be represented in form of a straight line.
According to the methods of mathematical statistics the results
obtained for different lubricants can be compared (Table 2).
The influence exercised by the additions to the fraction of the
oil of the type MS-14 upon the pitting was determined by means
of the distribution according to Styutent (Ref 4), (Table 2).
Additions of MoS 2 considerably increase resistivity to pitting,
whereas small additions of colloidal iron showed no particular
effect. Papers by V. I. Romanovskiy (Ref 4) are mentioned in
the text. There are 2 figureal 2 tables, and 5 references, 3 of
which are Soviet.

Pitting Failure of Steel
PERIODICALt Zavodskaya laborstoriya, 1960f Vol 36, Nr 3, PP 375-377 (USSR)
TEXT: The modified friction Aachine suggested by V. F. Pavloy (Ref 1) makes it
possible to perform a relatively simple study of the effect of lubricants on the
pittings formed in consequence of fatigue on friction balls. Work with this
model machine differs somewhat from work with the usual-type friction machines
by the fact that there.are very high contact potentials, a special recording
apparatus, and that a considerable spread of measured values has always to be 6
considered. These problems are discussed in the present case. Because of the
high contact pressure in the friction unit, the casing must be made of steel of
the type ShKh (hardness Be - 60-62), and must be kept in a thermostat. The end
of the test is established by means of a special sound-measuring device since
the formation of pittings changes the acoustic frequency of the friction unit.
.g device is given (Fig 2) which shown that an

T3XT: The anti-pitting properties of oils have been evaluated on a
4-sphere friction machine, in which the lower spheres were free(under
rocking condition4, by noting the time PT required, at constant 'load until
pitting appeared on the track of the upper sphere. The spheres were 12.7mm,
in diameter, and wore made oftLX-6 (ShKh-6) steel. The hardness of the
lower and upper spheres was 62 and 56 Ro, respectively. The speed of the
upper sphere was usually 1500 rpm, the load on the upper spheres was 390
and 300 kg, arid the oil tomporntura wAa '20 knd 800C. With oils frao from
additives (oil M -14 (MS-14)) PT decreased with an increase in temperature
from 20 to 1500C, whereas in the presence of additives (oilhT-16 (W-16)

and lubricant Tsiatim-208) PT remained constant between 20 and BO'C. The
retardation of pitting by lubricants is shown to depend on the viscosity
of the oils,on their chemical composition, anu on the presence of
additives. The PT values for various oils and their fractions are given
below (oil type, temperature, load in kg, and PT in min arQ listed):
tractor transmission (without additive), 800C, 390, 93; sulphurized tractor

anti-oxidant to synthetic oil lowored ito FT 4-5-fold. Addition of i!. Of
L'o S2with a particle size ~20 for 951,4 of the particlou increased the FT

that the problem (l)-(2) can be solved in an analogous manner for
integru-differential equations of the type of Volterra, and that the
described method for an approximate solution of such an equation can
be transferred in the same manner to the solution of the Cauchy problem
