.'ABSTRACT: Automatic argon'-shielded.arc weldingIof VT14 and VT6S titanium-alloy sec-
2-18 um thick has been studied in an attempt to obtain welds with a tensile
strength of. 115-120 kg/um~2 at satisfactory ductility (bend angle of at least 35* and
anotch toughness,of at least 3.5-4.0 mkg/cm2).It was found that in sections up to

over 6,mm th1ck,q;m=__mercL1 low-alloy wires containing a-stabilizing elements yielded
welds with asatisfactory ductility but a low strength,varying from 63.6 to

-strength but a low ductility. It is suggested that Ti-Al-V or Ti-Al-Fo-V alloy-weld-
~.,mnts over 6 =.thick be velded with fillers of the Ti-2.7AI-3.2 V system and used
inthe.annealed condition, which would ensure a tensile strength of 80-85 kg/mm at
a satisfactory ductility mind toughness. With an electrode wire containing 4.5-5%
aluizinum and 42 vanadium, the strength of alloy welds in the annealed and aged condi-
t4on can beincreased to.100-110 kg/mm2. This, however, requires the use of special
electrode wires, which are now being developed. Orig. art. haq: 4 figures and

TOPIC TAGS: automatic welding, heat compensator, steel bellow

melting electrode welding, argon arc, compensator lining, seam roll-
ing, seam testing, seam welding optimal condition
ABSTRACT: Automatic welding was investigated as a substitute for
the earlier, complicated process of manufacturing the steel bellows
used as heat compensators in gas and air ducts. The seams have to
be flat, since these bellows consist of 2 layers; hermetic sealing
is also required. Welding was done under argon by a non-melting
electrode, with subsequent rolling of the seams. A low current was
used, since high voltage leads to wide seams. For best results the
length of the arc should be:5 3 mm. The following empirical formula
was found for securing optimal conditions:

where H is the seam height in mm; is the thickness of the-strips
to be welded in umi; and B is the seam width in mm. In the te3ts
was 0.2 - 0.3 nim. The lining under the ~',qeams was preheated;
steel lining was found preferable to copper for hermetic sealing.
The seams were subsequently rolled; the machine used to this pur-
pose is briefly described. The best results were obtained with a
force of 250 to about 300 kg. Throughout the experiments, the
specimens were X-rayed for microfissures and tested for mechanical
strength. The editors remark in a footnote that such thin sheets
may also successfully be welded by pulse-arc. Orig. art. has: 4

ABSTRACT:
1his Author Certificate introduces a chamber for local gas shie-(!~ng in arc
welding of circumferential joints in spherical or cylindrical parts (see
Fig. 1) . The chamber consists of two hollow semicylinders, the side walls
of which have openings for the part to be welded and carry a 5Ls pipeliae
with nozzles for creating a laminar gas flow and a gas outlet. To ensure
airtight sealing in welding parts made of chemically active materials such
as titanium and its alloys and to make it possible to rotate the parts with-
out breaking the seal,-the joint of the semicylindere is built in the form

The author discusses several variants of the formulation and generalization of the
theorem, and the converse thereof is proven. REVIEWER'S COMMENT: The au
thor's formulation of the theorem's converse can be streng,thened by first pro,. in~~
the existence of a function V having continuous derivatives of any order with re-
spect to all of the arguments, the sole assumption being that said function fulfills
the conditions of uniqueness of the solutions (e. g., that it fulfills the Lipshits stip
ulations with respect to xj in each of the o < t < T intervals). The author's proof
of the theorem's converse contains inaccuracies, which, however, can be corrected.
It is not clear just what the author means by stating that the well-known theorems
of Lyapunov's second method are irreversible, since the converse of Lyapunov's
theorems [ Ustoych.ivost' dvizheniva, teorema 111, p 92 (The Stability of Motion,

TITLE: DxrectioxMr1CnffpMr for Hol Wave in a Round Cross-Section Waveguide
(Napravlennyy otvetvitel' dlya volny Hol v volnovode kruglogo secheniya)
PERIODICAL: Radiotekhnika i Elektronika, 1957, Vol 2, Nr 1, pp 65-74 (USSR)
ABSTRACT: Coupling between a round cross-section waveguide and a measurirg
channel is considered. By mathematical analysis, the conditions for separa-
tion of mode 1-10, wave from other modes are found, and design formulas for
coupling factors, for directivity, and for suppression of undesirable modes are
obtained. Theoretical calculations are verified experimentally.
The main difficulty in designing directional couplers is in obtaining a high direc-
tivity combined with suppression of undesirable modes. The article offers a
new device (figure 1) which appears to overcome the above difficulty better, and
suggests an analysis of the device by Ya. N. Fel'd's method (reference 2). The
device secures at least a partial division of the elements that materialize direc-
tivity from those which effect suppression of undesirable modes. A rourd wave-
guide is coupled by means of a series of apertures with four small equidistant
Card 114

Directional Coupler for Hol Wave in a Round Cross-Section Waveguide
rectangular measuring waveguides Conditions of excitation of electromagne-
tic waves in the measuring waveguides are explored mathematically. Figures
3 and 4 illust:rate how modes H 11, H 31, F1 21, and other undesirable modes are
eliminated. The longitudinal system of apertures helps in the suppress:or- of
undesirable modes and serves as a directional element (equations 15 thTrugh
21). Engineering design formulas for directivity factor, suppression factor ,
and coupling factor are derived (formulas 22 through 29). A better directivity
factor can be obtained with a system of different-sized apertures (figure 7).
Engineering design formulas for the three above factors are derived for this
case (formulas 30 through 39). Two experimertal models, with similar aper -
tures and with different apertures, were tested within a 8,600-19,600 mc band.
Model data is given in the table on page 72. Theoretical (dotted line) and ex-
perimental (solid line) values of directivitv, coupling factor, and suppression
factor are presented in figures 8 and 9 for models I and 2, respectively. The
experimental suppression factor exceeded 40 db. The azimuth system of rec -
tangular guides coupled to the round waveguide by longitudinal rows of apert,:res

Directional Coupler for Hol Wave in a Round Cross-Section Waveguide
permits taking off the energy of one definite mode. High performance of the
directional coupler is secured by suppression of those undesirable modes
have! a phase constant close to that of the desirable mode by means of an az-.m,-tl,
system of rectangular guides. Other undesirable modes are suppressed bV a
longitudinal set of apertures. Results of the analysis given in the article are
applicable to a directional -coupler design for any mode of waves propagating in
a round waveguide or other weak-coupling measuring device. Calculations and
experiments with the directional coupler have shown that with 2R/x!~~ 1, 6 satis -
factory results can be obtained with only two rectangular guides and a simple
longitudinal row of apertures. With a higher ratio of 2R/.,,, the coupler can be
used along with conical smaller -to -larger diameter joints. The above-described
coupler models permit measuring, at Hol mode, in round waveguides, the fol -
lowing magnitudes: small (30-40 db) reflection factors, power passing the given
cross-section of the waveguide, mode Hol attenuation in various waveguide ele-
ments, and losses associated with transformation of Ho, mode into other modes.
