=T: The graphical recording of pulsating movements of the c ar-
diac vessel cluster as observed using X-rays el. kymography, is used
for diagnosing not only cardial vessels but also pulmonary diseases,
e.g. cancer. The model M-60 has been approved for series induc-
tion. It permits simultaneous registration of the elctro-cardio-
gram and of one of the following processes: The pulsation of heart
periphery and of large blood vessels, the capillary pulse of the.
pulmonary parenchyma, diff. pulmonary ventilation. It is also pos-

sible to register simultaneously the diff. pulmonary ventilation of
both lungs or of any 2 electrocardiogram connectors. Either a stat-
ic or scintillation slot diaphragm probe is used. The probe oscil-
lations are applied simultaneously after amplification to a recorder
and an oscilloscope. Provision is made for signalling in case the
probes and indicators are located separately. The construction is
given of the probe together with the diagram of a 2-channel balanced
photo amplifier with noise compensation circuits and of a 2-channel
oscilloscope and of power supplies. The recording channels from
the scintill'ation and static probes have a frequency band 0.15 to
12 c/s and 0.04 to 8 c/s respectively. The horizontal oscilloscope
sweep is regulated from 0.01 to 10.0 sec. The overall equipment
power consumption is I WA. Results of clinical experiments are

PATIENTS (Russian text) - P o m c I t s o v K V. - VESTN. RENTGENOL.
RADIOL. 1957, 32/2 (21
The author investigated the influence of antibiotics and chemotherapy on 210 pa-
tients suffering from pulmonary tb. During 6 months 61 cavities were healed. In
the cases of focal and infiltrative forms 5016 of the cavities were healed. in the
cases f haematogenic-disseminate forms the percentage of healed cavities reached
30 nd0i'n cases of chronic fibrous -cavernous tb the treatment had almost no effect.
In the process of healing roentgenological investigations show 3 phases. During
the first phase the walls of the cavities grow thicker, their external contours be-
come less sharply pronounced and a small fluid level can be observed inside them.
During the second phase the lumen of the cavities concentrically decreases they
change their form and shadows ap 'pear in the adjaicent lung tissue. During tLe third
phase the walls of the cavities lose their contours and change& are observed trans-
forming the cavitiesl into limited indurated areas.

TITLE: Some theoretical problems in wrap-around grinding
SOURCE: Moscow. Vyssheve Obrabotka metallov rezariyem I

TOPIC TAGS: metalworking, machine grinding, metal finishing
ABSTRACT: The paper deals with a study of certain aspects of the high-speed wrap-around
method of grinding. This method, since it is free of the normal limitations imposed by
wheel coupling rigidity, permits grinding rates of from 115 to 135 m1sec. Mathematical
expressions are derived for productivity ratios in this kind of grinding. E'quations are aral-
yzed which mqkc it possible to determine the length of the wheel contact arc as a function of
various other factors. In this way the author succeeds In establishing certain grencra] laws
with respect to high-speed wrap-around grinding, demonstrating, In particular, t1hat the best
results in terms of increased productivity are obtained when grinding pieces which are largf!
In diameter, and that the diameter of the wheel should not exceed the diameter of the workol
piece by more than 2. 5 times. Orig. art. has: 4 figures and 13 formulas.
