TITLE- The Problem of Searching in Modern Aviation
PEFIIODICA,L-- lfojskoiiry przegl~d lotniczy, 1959, Nr 12, pp 6-11 (POLAND)
ABSTRACT! The author defines searching in aviation as systematic space
scanning in flight, body and head shifting, and points out that,
proper searching is important in flight safety. He implies that
obsolete methods in "search training"have to be modified.be-
cause they do not ensure sufficient safety under present flight
conditions in.the "overcrowded" air. Two hypothetical examples
of aircraft collisions are described. A jet aircraft and a bank
ing piston engine aircraft collide although both pilots carried
out correct "searching" according to'the:conventional scannimg

the piston engine aircraft which banked in from starboard. The
second hypothetical collision involvestwo.jet aircraft, one in

aircraft shows that probablythe most useful "searching", system*
will be conical scanning in the flight direction. The best watch-

Abstract: [Authors' En-lish summary modified] Tests for R.
coli in the stool and fors.specific serum antibodies in -160
cases of infant-diarrhea lead the authors to the conclusion
that these tests can be used for diagnosis, that serological
tests are more reliable than the bacteriological ones, and
that the passive hemagglutination and indirect hemolysis
tests are sensitive enough to be conridered reliable. The
4-3 cited references include one Russian, about 15 Polish,
and the others Western.

TITLE: Stabilization of polyformaldehyde (PFA), Part I.
PERIODICAL: Przemysl: chemicznyq v. 41, no. 1, 1962, 40 43
TEXT: The object of this work was to compare the effect of a num-
ber of anti-oxidants on preventing the decomposition of PFA. 23
Commercial anti-oxidants, chiefly amines and phenols, were tried on
acetylated PFA, by measuring (1) the thermal degradation coeffi-
.cient, k, defined as the percentage lossin weight per-minute on
heating at 21000 and (2) the reduced viscosityg at 1400C, Ubbeloh-.
viscometer was employed for the latter tests, on solutions
containing 0.5 g PFA in~100 ml of solvent (dimethyl formamide'+,
0. 5 % diphenylamine)., Measured quantities of stabilizers were added
to the PFA which was then treated according to ASTM.D 1238-52 T and,
-tested-as above. It was.found that the most effective stabilizers
,~were the aryl derivatives of naphthylamine and p-diphenyl diamine
and several alkylated phenols. Organic sulphide-s showed no stabili-:.

stabilizers at 21000, showed that the optimum concentrations were:

is therefore thought to be the best. Further research on the sta-
bilization oil PFA will be carried out using mixtures of anti-oxi-
dants and polyamides and determining the induction period before
decomposition. There are 5 tables and,16 references: 3 Soviet-blot
