ABSTRACT: A method is proposed of' calculatine, the time for
the removal of surplus charge carriers from the
base of' a transistor.trIode. It Is applicable to
pulse circuits. The influence of saturation on the
build-up time and width of multivibrator pulses is
Investigated theoretically and experimentally for
two-junction trIodes. Introduction. 1. Calculation
of' carrier removal time by the charge method. The
equation of conservation of the total hole charge In
the transistor triode base is

previous work by V. A. Kuz'mIn (Izv. MVO (Radiotelchn-tka)
1959, 2, 5) it was shown that in the first approximation

In the illustrated circuit the multivlbrator triode
ITrIT/1 is assumed conducting but 1111T 2 is non-
conducting. The capacitor Is being recharged, voltaCe
at IIIIT I base drops close to zero and the trIodc
conducts. A part of MUT collector current f'lowu
to the base of IIrIT 2 and bole removal of thlo base
starts. While the rIrIT2 collector potential remains
close to zero, the feedback to III'IT 1 is Inactive and
I:11IT1 continues to operate as an amplifier. The
feedback commences only after the end of the removal
of surplus carriers from TIEET 2 base, and a fast
,regeneration process starts. Thus, saturation causes
a considerable Increase of the front pulse of collector
voltage of the conducting triode. The partial charge
loss by C 2 during recombination shortens the flat

saturation the multivibrator oscillations may be
disrupted. The removal time is calculated under
the following simplifying assumptions: (1) The triode
characteristics are linearly segmented. Triode begins
conducting at Vb = 0, and its parameters Rin' Rout,
'a, and Cout--~,31 Ck assume their constant magnitudes
abruptly. (2) The input resistance of the saturated
triode may be ignored since it Is considerably lower
than the external resistances of the circuit. (3)
The collector current during removal is constant and
equals Iks ~ Ek/Rs.

(3) was determined without con*ideration of charge loss

usual methods at base currents and collector voltages
corresponding to the circuits, and then averaged.
Comparison of theoretical results with experiments
showing approximately 30% difference, proves the correct-
ness of the method of calculations, the difference being
caused by simplifying assumptions of the equivalent
circuit and the averaging of triode parameters. There

ABSTRACT: The welded steel tube production,line of the
Chelyabinsk Tube Rolling Mill (Chelyabinskiy
truboprolm~tn7y -.zavod) is based on a newly developed
technique of bending the tube from strip in 12 m
lengths. The cut strip is first bent into a shallow
channel with rounded flanges. Theik the channel is
folded to produce an oval section with flat sides
which is subsequently formed into a round slotted
tube. The edges are brough together for welding, after
which the tube is calibrated by expansion, straightened,
heat-treated and tested. The bending operations are
carried out on standardized hydraulic presses after

TRANSLATION: In the frames of one-dimensional theory there are expounded basic
questions of flow of gas in the channel of a supersonic diffuser --reversed Laval'
nozzle--in off-design conditions. Expounded method allows one to understand physical
processes and produce simplified calculations of diffuBers In sketching and long-
term designing. The reversed Laval nozzle works stably only in off-design
conditions. All off -design conditica a can be divided into two groups depending

change of reduced incident flux velocity. The first group of off-dc3ign conditions

!of flow is obtained as a result of change of back pressure at the diffuser outlet
at a design value of the reduced incident flux velocity. Flow of gas is possible
only in the presence of a shock wave in the expanded part of the diffu9eq. If
'back pressure at the diffuser outlet is increased higher than design the'shock
'wave leaves the bounds of the inlet, forming a detached bow wave. Therc are
graphs of the change of reduced velocity and pressure along the diffuser in off-
;design conditions with a detached bow wave. There is expounded a method of
-calculation of conditions with a detached bow wave, conditions with overexpansion
and terminal shock in the expanded part of the diffuser. There are given design
curves allowing us to determine at what conditions the back pressure in a
,condition with a detached bow wave may be less or larger than design. The second
;group of off-design conditions is obtained during deviation of the reduced
lincident flux velocity from the design value. Flow of gas in the expanded part

"At a given degree of the compression, the coefficient of pressure bears a
definite relationship to this velocity. The author aaawnes that even with a
significant error in the selection of velocity, the error in the coefficient of
pressure would be small and it would therefore not be necessary to make a
secondary approximation for the coefficient of pressure,"

ABSTRACT; In the analysis of the characteristics of supersonic
compressors, the air intake problems of jet engines as
well as other applications of supersonic diffusers, it
is important to understand the peculiarities of these
diffusers when they are working under conditions which
differ from the design conditions. The paper presents
theoretically derived characteristics of such a simple
diffuser (Iaval nozzle in reverse) and discusses the
types of flows possible under different conditions of
operation. For the sake of clarity of discussion of
the critical phenomena (chocking, shockless transition
through the sonic speed, shock formation etc.) the
analysis is simplified, i.e. basecl on the one-dim-e-asional
theory, friction is neglected and the oblique shocks are
exclucled.. Consider a diffuser with its inlet section

and its exit section (Section 2-2. Fig.1) under the
influence of the remainder of the propulsive system,
which will decide the back pressufe no matter what are
the conditions at the inlet to the diffuser. The
intermittent section is determined by the continuity
equation as specified by the design requirement, i.e. so
as to ensure the required mass flow rate Gp (the suffix
p denotes design conditions) at the required speed as
specified by its rediiced (nondimensional) value
~'op = Wop/aKP-p (here the suffix o denotes free stream
conditions p - design conditions, Kp (12%r) - entical
conditions5. At the design conditions there is no
distortion of the streamlines upstream of the inlet
section (fo = fl), the flow is supersonic in the convergent
portion of the duct, becomes sonic at the throat and
reverts to supeisonia in the divergent portion. Fi 1~
