TITLE: A method of producing strengthened articles from synthetic
resin and a granular material
PERIODICAL: Referativnyy zhurnal.. Khimiya, no.22, 1962, 539, abstract
22P388 (Hungarian patent 146405, Sept, 30, 1961)
TEXT: In order to strengthen systems consisting of a synthetic resin and
a granular material (GM) the surface of the grains is coated with an
intermediate layer. This layer adheres more strongly both to the
synthetic resin and to the GM thian they adhere.together directly. The
intermediate layer (epoxy resin, organometallic compounds of resins
produced from them such as metal alcoholates, intracompleic compound of Al
and acetoacetic ester, metal phenolates, phenol-formaldehjrde resins) is
.applied directly to the hot GM (MgO, A1203 1 Si021 ZrSib 4) whilat being
agitated.in a solvent, which is afterwards removed. Example. Sand heated
to-2200 C is mixed with a quantity of epoxy resin emulsion such that after

removal of the water the layer,of epoxy resin coating the grains weighs
-0.1 % as much as the sand. After the resin has,become uniformly
distributed, novolac phenol rqpin amounting to 2i5 - 3 % of the weight of
sand is added and is stirred for 2 - 3 min; then hexamethylenamine
amounting to 10 % by weight of the phenolic resin is added whilst ooolingi~
and stirring vigorously; stirring is continued for a further 5 min.

Abstract: In the determination of oxidizing agents by the ti-
tration of the solution of N2~4.R2SO4, the end Point
can be established (in addition to the potentiometric
method) more easily by the aid of the Iodine-Starch
indicator (one drop of the alk. iodine soln. plus one
ml of the starch solution). An example is the deter-
mination of bromate in the presence of Br- ions. Dur-
ing the titration, the solution is colorless because
IBr does not react with starch.

Abstract : The author reports on thD possibility of determining
S2-, SX2-, S2032-, and SO 32- in mixtures by using 4
portions of unknown solution. The analysis is based
on the fact that the first three of the above ions
react with unequal amounts of 12 and Br2 and are oxidized
to products of different composition. When an unknown
solution containing the above ions is boiled, S from
H2S and H:~S03 is removed as S02; S from, H2SX and H~S203
can be doterEined in the solution obtained by oxidation

Caffeine reduces respiration in the heart of both normal and hypoxic animals.
The improvei'hent of oxygen consumption in the functioning heart is probably due
to the greater blood supply to the heart. Caffeine has no appreciable effect on anae-
robic glycolysis and carbohydrate metabolism. In the hypoxic heart caffeine inhibits
the increased breakdown of ATP and glycogen. It is this protective effect of caffeine
that is supposed to involve a reduction in the oxygen demand of heart muscle. -

"Ragulation of the Fibrillatory Tendency of the Heart in Hypoxia"
Budapest, Acta Physiologica Academiae Scientiarum Hungaricae, Supplement
to Vol 22, 196-3; P 11 -
Abstr.r-L [Authors' Dnglish summary, modified]: The correlation botween
arterial hypoxia and the tendency to atrial and ventricular fib:rillation
has been studied following total or partial elimination of the jaervous
control of cardiac activity. It was found that a hypoxia of the central
nervous system is responsible in the first place for the increase in
the tendency to fibrillation in hypoxia, through stimuli reaching the-
heart by vagal mediation. In chronic hypoxia the tendency to fibril-
lationis decreased, presumably as a result of an exhaustion of nervous
centers.

TOPIC TAGS: cardiovascular system, hypothermia, cat, pharmacology
ABSTRACT: The effect of stimulation of the right peripheral vagal stump as well.
of acetylcholine injection or infusion on the fibrillation threshold of the_.._,_
auricles and ventricles has been studied in anesthetized cats as well as
in the isolated Langendorff heart of cats,at different body and perfusion
.fluid temper-atures. The lowering of fibrillation thresholds by vagal
~stimulation or acetylcholine was more pronounced at lower body temperatureal
'i.e. hypothermia increased the sensitivity of the myocardium to
vagal influence. In addition, arrhythmia and %entricular fibrillation upon
-vagal stimulation, acethylcholine infusion or injection appeared more
frequently at lower than at norml body temperatures. These are only valid
for the arrhy-thmogenic and fibrillatory vagal effedts since the intensity
of the negative chronotropic action of vagal stimulation and of acetyl-
choline injections is definitely diminished by hypothermin. The possible intet-,
pretations of this discrepancy and the mechanism of the' enhanced fibrillatory f..
effect of acetylcholine and vagal sti.mulation in hypothensia are discussed,
