TEXT: A team of the gravimetric department of the Ge~physlcal Institute at
the Czechoslovakian Academy of Sciences has compiled, as a resul-~ of 5 years of
work, a 1:200,000 map for the entire territory of the republic for calculating
gravity corrections. Corrections are introduced, with an accura3Y of 10.5 mgal,
for the relief within the Hayford zone 0 for density 2.67. Sepamte sheets of
the map are presented for mountainous, hilly and plain regions. Isolines of equal
correction values are dra-em through 0.2 w-gal. The Earth's curvature is taken into
account. The values obtained from the map should be added with a correction
determined from the appended nomogram for the height of the poirits and a cdrrec-
tion, calculated for every point, for the effect of relief masses within a radius

of 5.211 km. The nomogram yields a part of correction for relief'In region (G),
statistically determined, varying regularly with the height. The size of this
region Is chosen so that corrections indicated on the map chould'not depend on
the point heights. A sheet of the 1:200,000 map Is taken for thc. region G.
Maximum values on the maps are - 5 mgals. Topographic and hypsoffetric maps, be-
ginning from scale 1:100,000 are used for calculations. Corrections are calculat-
ed for special points of the relief indicated on the maps. About 40 points were
fo'r each sheet of the 1:100,000 map; in mountains - sometimes 200 points and
more. Calculated values are presented on the maps. The effect o,' zones M and 11
is determined for four points on the 1:100,000 sheet, and that of zones 0, and 02
- for one point. For each quarter of the sheet indicated a graph of dependence
of zones M - 02 on tho point height is plotted, and this effect ie determined for
all points of the section. Graphs of adjacent sections determine.the effect of
zones M ~- 02 with a difference of, in most cases, -.,0.01 mgal. In high-moun-
tainous regions of Slovakia the sections are reduced. If any dependence of gra-
dients of quantities presented on the map on relief heights was no~jiced, the
heighte of locality were taken into account while drawing th-i isolLnes, For tho
control, corrections for relief were calculated for 207 pointa uni"ormly distrl-

determining the influence of zones M - 02 is estimated by the authors In j~0.1 mgal.
They suppose that errorc of Influence of zones I - L do not dtpand on the poInt
helchts. The me-in error of this influence In estimated to be t0.04 nigal. A table
is presented for Bullard's term: a difference of effects on gravity b.-tween the
spherical layer within the external radiur, of Hayford 0 zone and infinL te plate
of the same thickness. For zones H - 0 2 a correction.table is given'for rurvature
of spherical layer. A table Is also given of effects of z9ne A and set-tors of
zones and aubzones B - 11 on corrections for relief (up to 0.001 mgal). It Is
shown in tables, which accuracy is required for mean heights in these :-.ones and
subzones for calculating their effect with an accuracy of 0.1 and 0.2 ngal at
mean elevations close to zero and 100 m. It is shown alsa, what an accuracy is
required for determining mean heights in sections of zones I - 02 for calculating
their effect with an accuracy of 0.1, 0.2, 0.3 and 0.4 mgal at mean elevations of
locality 500, 1,000ffl- 1,5W 'and 2,000 m. A map of topographic correcticns for V/
zones 18 - 1 of Hayford for Czechoslovakia is presented. A map of topcgraphic-
isostatic reductions,~.of these zones has been prepared. For 14 points, Anfformly
distributed over-~h~-IjArid--iirriiory, the table gives effects of topogra?hic

ABSTRACT: The method of inti-aosteal injection of penicillin
and novocain presented in this article is based on
its specific etiotropic effect on microbian stimuli
(staphylo- and streptococcus) and on the pronounced
general: effect of antibiotics, which spread out via
the venous and arterial vessels of all tissues of
the extremity after being injected with a solution
of novocain into the substantia spongiosa ossium.
Besides this, a weak solution of novocain affects

inflammatory focus iii the cortex of the myelencepha-
lon and improves the trophicity of the tissues in
the area of the inflammatory focus. The method had
good.results in all cases of acute purulent diseases
of the fingers and the carpus. According to the
author's opinion, panaritia and purulent injuries
of the cai-pus as well as phleSmons in initial forms
can successfully be treated with an intraosteal in-
jection of novocain and penicillin without surgery.
Purulent panaritia have to be opened,~ but the pro-
phylactic application of the above mentioned method
considerably simplifies the operation and accelerates
the healing of the wound. This simple method can be
employed at dispensaries and dressing-stations.

TEXT. The teohnology of the impregnated cathode is briefly
reviewed. It is shown that.this modern cathode can serve as a
powerful electron source having a long life and that It is
immuneto high voltage gradi-ents and gas impurities. Due to
these merits of the cathode it is possible to employ it in
special hIgh-power microwave tubes. The basic chemical
phenomena occurring in the cathode and its emission mechanism
are explained. Particular attention is paid to the manufacture
tet,,hnology of the cathode in order to obtain optimum emission
characteristics. The technological processev involved in the
preparation of the cathode material, composition and preparation
of the emibaivo mtitorifil and the Impr @grin 11 on tonlint(lue are
extremely important in secUrtng the required properties. The

PERIODICAL: Slaboproudov~ obzor, v. 22, no. 6, 1961, 338-342
TEXT: , The article lists requirements imposed on modern power
cathodes and describes the development, design, properties and
functions of the "impregnated" cathode which is a powerful electron
source with long lifetime and high resistance against steep volta-
ge gradients and,residual gases. The development of,microwave
technique imposes increased requirements on the emissive roperties
of power cathodes. Since conventional cathode materials T porous
Ni coats, thoriated tungsten, boride) do not meet these require-
ments, efforts are being made to find new cathode materials. The
first achievement was the L-type dispenser cathode which, however,
has the,disadvantage that it is rather complicated and hard to
produce, A similar, so-called "impregnated" catbode with very
remarkable properties was*developed by R. Levi (Ref 3,improved

639,/. Basically, it is a barium cathode with a porous tungsten
coating impregnated with molten Bl-Ba oxide. The impregnated cath-
ode is considered the most powerful, long living electron source.
Such a cathode, tested at.the VdVET-V~zkumn~ fietay pro vakuovou
elektrotechniku (Researdh Institut~ for Vacuum Electro-Engineering)
in Prague with 6 load of 1006 A/cm at 1.1200C, supplied with an
anode voltage of 145 V, had a lifetime of 5.000 hra without emis-
sion loss. The rather 2low operating temperature of 9000C at a con-
tinuouB load of 1 A/cm increases the lifetime of an impregnated
cathode to several ten-thousand hrs. To achieve the beat resultaq
vacuum conditions must be optimal. However, the cathode is
relatively poison-probf, operates dependably even under certain
detoriated vacuum conditions (current densi tie a are lower)t and
withstands several times the contact with air of atmospheric pres-
sureq when activated. The emissive surface of the cathode is very

.hard, compact and amooth and resists very steep voltage gradients
(ia the order bf'several tens of kV/cm), and bombardment with
positive ions.-The resulting secondary emission contributes con-
siderably to magnetron functions. The ratio of primary to abcon-
dary emission ( factor)~) of Ba 3Al206- impregnated cathodes is
much larger than that of dispenser cathodes, which is attributed
to the emission.from pore ends. The rather steep initial decline
of'secondary emission can be balanced after several minutes by
increasing the cathode temperature to 1,2000c. Comparative tests
were madewith L-dispenser and impregnated cathodes (emitting
material 6BaO.2Al 0 CaQ) both employing tungsten bodies with
pcrositieB of 25 Q045%.' The emisuion factor'~,for L cathode was
found to be 1.6 for a tungsten porosity of 25% and 1.45 for a
tungsten porosity of 45% and dropped slightly after 30 min. of
electron bombardment. The factor )( of the impregnated cathode
with a tungsten porosity of 45% was 2.8 and dropped to 2.25 after

15 min. of electron bombardment. The factor of secondary emission
wasapproximated 4.2 and dropped to 3.0. An impregnated cathode
with a-tungeten porosity,of 250 had an initial factor%of 2,15 and
a final factor X of 1.7 ;.the pertinent emitter material had an
initial y, 0f'3.8 and a final X of 2.0; The chemical reaction
taking place in the porous tungsten layer can be formulated as
follows: Ba.A1206 = 2BaO + BaA120,, BaA'204= BaO + A1203 I
6BaO + W = Ba + Na. The liberated :Ba migrates on the tung-
3WO6
sten..surface and forms an emitting monomolecular layer. The very
strong binding.of the Ba to the W, caused by the oxygen interlayer,
brakes the Ba emission which, otherwise, would be too fast and

a measure for the lifetime of the cathode. Since the first impre-
gnated cat-hodes did not reach the above-described emissive proper-
tieR, th'kry~were improved by levil who added OaO to the emitting
,substance, thus quadrupling the emission. The functibn of the CaO
is not quite illuminated, but it is supposed that Ca2BaWO6 results
as reaction product which does not attenuate the emission. The
Impregnation, originally.performed in vacuum, is not perforrued in
a hydrogen atmosphere. Due to lower Ba evaporation, the improved
cathode has 8-times the lifetime of the original impregnated cath-
ode. The production process for impregnated cathodes, as developed
by ;he VdET, is then described,, The base of the cathode is a pelle
or tube-shaped body of porous tungsteL, impregnated with the e ~L-IK
ting substance. The most effective emitting substance is composed
of 7 g BaCO 3 9 1.2 g A1203. ( in form of corundum with a grain size
of lpm) and 1.0 g CaO. A 20% excess of BaCO was used to

compensate for partial evaporation during impregnation. The mix-
ture wab ground-till all were smaller than 1 Wm9 and then suspended
ill 15 ml acetone. The pellet or tube-shaped cathode bodies are
pressed from 2j~m W powder with a hydrostatic pressure of 2 tons/CM2
and then sintered for 10 min. by hf heating to 11600 - 198000C in
hydrogWatmosphere (which causes shrinkage of 8%). For better
machining, the bodies are impregnated with Cul which can be re-
,moved after machining either by nitric acid and subsequent boiling
in. distilled water, or by high-temperature vaporization i1ft H atmo-
sphere. Pure tungsten powder is used for its chemical affinity
to BaO, Admixtures of Mo are, not advantageous for highly-effective
cathodes. The effect of other admixtures ( Ta, Nb, Zr, Hf, etc)
is being investigated by the V6ET. The porogity of the tungsten
body ( which should be 30 - 40%) is checked by comparing the weights
of the same sample, first in dry otateg then soaked with distilled
.Yrater. The completed cathode bodies, after Cu removal and hf

annealing for 5 min. at 1,650 00, are impregnated by applying the
emissive suspension either with a brush or by dipping and sub-
sequent rapid hf heating to 1?750 - 1980000. As soon as the.
coating is absorbed by the W body, the heating*is discontinued and
the operation repeated twice, once at 210000C9 the second time
at 2)20000o After impregnation, reminders of the emitter are
scraped off and the cathode surface is ground with abrasive carbo-
rundum paper. After conventional evacuation of gases by pumping,
the impregnated cathode is gradually heated up to 112000C which
effects further degassing. Then it is gradually loaded with an
anode current so that the emission tendency increases. The emis-
sion current is controlled by the amount ofresidual gases re-
leased by electron bombardment and is limited by the maximum anode
lose.. When a stable emission is reached (after 20 - 30 min.) the
anode current is reduced to the operating value and the cathode
temperature is*reduced by 100 - 2000C. At this loadq the activation
is continued until complete stabilization of the emission. Tn'

regular evacuation conditions, the activation is completed within
1/2 - 2 hre. Only tubes for pulse operation need further activa-
tion at impulse conditions. In conclusion the author states that
impregnated cathodes with their remarkable properties can be wide-
ly applied, especially in microwave technique. The cathode pro-
duces great emission densities, has a long lifetime and resists
oteep voltage gradients, Due to its metal body, it also resists
mechanical damage and can be precisely adjusted. It is success-
fully'uaed in magnetrons, klystrons, carcinotrons, hv rectifiers,
betatr'one, and Hg-discharge tubes. There are 4 figures, 1 Soviet-
