;ABSTRACT: A reliable method is proposed for controlling the welding cycle.to produce
isilver contacts for telephone-type relays (Figure 1). Experimental data show that
J-66pacitor welding results in contacts with erratic.strength properties, while'AC weld-
!ing with the PIT-50-2~interrupter produces contacts with more stable strength proper-
Aies but without theproper shape due to shrinkage. The double-pulse ignitron ihter-
1rupter shown in Figure 2 is developed to provide theproper welding cycle with respect
'to pulse duration and stabilization of the initial state of the weld zone. Tvo igni-
~trons with controlle/ thyratrons connected in the ignition circuits'are used for cur-
,rent commutation. A phase shifter is used for controlling the ignition angle of the
lignitron which passes the first half-period within a range of 44-1270. The pcver unit

AB STRACTt For the calculgtion of the thermal field within the limits of the working
length of thq_AALr)*Wa during welding with German silver, it is sufficient to take!"
into accowA"OnlyVthe heat liberated at the contact resistance (CR) which decrease*
with increase in the contact temperature. The magnitude of shrinkage during T-typ
Ag welding with German silver is practically independent of the initial value of C
because after reaching the temperature of malting of one of the materials the
intensity of heat liberation at CR falls sharply.: Depending on the influence of "t
the initial value of CR during welding on the optimum time conditions during which',
the temperature at the contact increases to the melting temperature, there occurs
a change in the temperature (over a period of 4-18 msec) mad a corresponding change
in the bond strengthlat constant magnitude of,ahrinkage.of 80% from the average

group were exposed.to total body radiation with gamma rays (700 r)
emitted.by the rYT CO-400-1 (GUT CO-400-1) apparatus; 26 rats in
each group.were not exposed~to radiation. More experimental animals
from each group were killed on the 2nd, 5thp 10th, 20th and 50th day
after exposure to radiation. The mesentery and the omentum. of all
the killed rats were fixed with methyl alcohol and stained with
Romanowsky's stain. Paraffin sections of.,the.skin were stained by
the same me-thod, It.was found that in animals kept on animproved~
diet the number of mast cells increased above the control normal.
In animals kept on a diet relatively deficient in proteins and vi-
tamins, the number o.L mast cells was decreased* Gamma radiation cau-
sed a-decrease in the number of mast cells in both groups; this was
more marked in animals kepton a deficient diet. The number of eosi
nophil8 in the omentum increased.after exposure to radiation, to an
extent independent of the diet. There are 10 figures.

.Abstract: (German article) Acetates of the cyclic 2,4-dinLtro-phenylhydra-
zones of D-glucose, D-mannose, and D-xylose were obtained by treating these
compounds with acetic anhydride containing traces of quLnoline or pyridine
at a temperature of 80-120*C. The products of the reactions were investiga-
J,ted; however, their pricise construction was not established. Ultraviolet
and infrared spectroscopic data indicate that the three compounds are hyd-
razones containing one NH group each. Orig. art. has I graph and 1 formula.
