is 71n goEd agreement urith e!_kpovirnents for current densities up to
10 A/= . The ccithode can produce high powers (120 If continuously
or up to 300 M11 in pulses) and is very efficient. Its main dis-
advantage,lies ill the fact that it should be used in very well
evacuated devices. The second typo of fiold-onission device is
the Malter cathode, in which a strorgelectric field is produced
by positively charging the surface of a thin..dielectric film
deposited on the bathode base material. The-most successful
dielectric layer can be produced from ~jgo. The emission in such a
cathode can be initiated by irradiating it with a strong beam of
light or an electron boam. The period of irradiation is compara-
tively short and after that the omission current assumes a steady
value. The cathode is luminescent during its operation and the
intonsitY Of the luminescence indicates distribution of the emission
intensity over the'cathode surface. Durini-the sblf-maintairiing
operation of a NgO cathode, the phenomena occurring on ~he cathode
are similar to those of the Townsend avalanches observed in gas
discharges. Attempts have been made to use:the cathode- in

and absonce of a heater. flo-aever, the cathode suffers from tile
disadvantage of needing a starting "pulse" in the form of heat,
electron bombardment or irradiation. In the so.:.called 'capacitor-
type' cathodes, thestrong electric field necessary for emission

ABSTRACT: Some aspects of the continuous-wave radiolocation method offer certain
advantages over the pulse technique employed in the oporation of radar equipwnte
The continuous wave reflected badc into the transmitter station makes it possible
to measure: 1) the distance of the target, by frequency MOdulating the difference
frequency obtained by mixing the tranadtter and receiver waves; 2) the target
velocity in the transmittor-roeo1ver direction,, with an unmodulated wave of DOPPLER

frequency; 3) both the distance mid velocity of the target, by moans of frequency
nodulated wavos (WITTM-R method)* The first of these techniques is applied to the
~frcquency-modulation altitude meter for continuous tracking of elevation above
.ground ranging from 2 meters to 1500 or even 6000 motors with an accuracy between
;2 meters to 20 centimetors, depending on the instrumant, design. The general prin-
-ciplo is based on effecting a dolay between the wave coming to the receiver directly
~from the transmitter and the wave which arrives at the receiver after reflection
:from grounde The nixing results here in the generation of a difference frequency
which is proportional to the displacemant between both received waves. This moan
';difference output Is then amplified and the resulting voltage is sent through a low-
,1pass filter* Subsequent differentiation and rectification yield a mean direct cur-;
;rent proportional to the mean difference frequency. If a singlo target is tracked i
:,trith such equipment., then a step effect appears in readingso This effect is not
:significant at high altitudes, but it becomes Important at low heighte In order to
!reduce this effect,, a large frequency deviation must be chosen; this would mean a
wide bandwidth and make it difficult to attain the no cessaa7 sensitivity f or high
altitudes& Consequentlyj the Instrument is made to operate differently for a low
altitude range (feeo 0-3$0 m) and for a wUs range of altitude (f *as 0-2500 m),p by

transmitter-target-rocaiver lino. The reflected wave and the unnod
mitter wave are mixed at the roceiverp the difference frequoncy is then amplifiod
and calibrated Into noters/second roadingse Since the DOPPLER Instrument operates
on unnodulated waves) it Is practical to employ high frequencies. The resulting
advantages are: small sharp-focuning and easily camouflaged antennas and simpla
porate, with narrower rocoiver
transmitter construction. Also.. such Instrument can o

operation of this DOPPLER equilment 2onds itself furthermore to automated toch-
niquess Its application ranges from street traffic and maritime traffic to the
Devon rwre significant air traffic problem 9 Navigation is possible without the use
of ground stations; the speed of the airplane is deteminod by at least three beam

.syste-za in space. Computers am used for these operations* Ono difficulty with
*this type of equipment arises from the fact that an ideally mwoth ground surface
reflects only a small portion of the Incident radiation and gives no DOPPLER shifte

'attained by oither of two methods: a~ sampling the transmitter (repetition rate
'50 kilocycles/second., pulse duration 4 microseconds) and mixing the signals from
:antonaas located at test points b) frequency modulating (rate of mockilation 400
ikilocycles/second,, deviation 5%~, then mixing transmitted and received frequencies
directly. The instrument can also be tuned to higher harmonies of the modulation

TEXT: A new method for growing crystals from the molt has
been developed. Its main features are: a) a cooled stationary
holder for the seed; 'b) a crucible which performs a reciprocating
rotary motion and is simultaneously lowered. Some advantages of
this apparatus are an follows. The growing crystal is stationary
and therefore free from vibration. The reciprocating rotation of
the crucible helps to remove impurities. The crystal can be grown
relatively easily in vacuum or in any chosen atmosphere. The
growth can be continuously observed. The bottom of the furnace
in which the growth occurs is heated and by regulating the input
to this heater the temperature distribution 'in the furnace can be
altered. Another heater is wound in the wall of the furnace in
such a way as to ensure a long zone of even temperature. The

temperature in the furnacqmust not only be controlled but also
programmed in order tq ensure that, as the phase boundary moves,
it should remain at the temperature of the melting point of the
substance. All the'measuring and control devices are located in
the heavy base of the instrument. The furnace forms a separate
unit which rests on the base and in thus readily exchangeable.
In order to increase the flexibility of the equipment, a
mechanism for the motion of the need-holder can be added. This
allows the use of the equipment for annealing the a-ystals or for
growing crystals by the Kyropoulos method or by a combined motion
of seed and crucible. This method is being studied further; a
patent has been applied for. Alkali-halide crystals with &ameters
up to 13 cm have been gr6wn in the equipment during test runs.

TEXT: Practical problems in the growing of single crystals of
alkali-metal halides by the Kyropoulos withdrawal technique are
discussed. At the very high temperatures of fusion there is some
volatilization of the alkali metal hilide which diffuses through
the refractory wall of the furnace and may lead to corrosion of the
embedded heating elements- An improved unit is described which
provides a better refractory material, a more accurate temperature
control and a special corrosion-resistant lining for the furnace
wall (subject matter of Czechoslovak Patent Application
3 538/mPst 8-56). The refractory material consists of a mixture of
white, synthetic corundum and clay, fired at 600-700 *C for 8 hours.
Its porosity is reduced by soaking in a solution of AlF3, followed
by treatment with NH4OH- A precipitate of aluminium hydroxide gel

is deposited within the pores of the refractory mat.crial. The
improved temperature control is provided by a platinum resistance
thormometer, wound upon a corundum former and housed in a silica
sheath. To reduce heat losses, the walls of the furnace nust be
as thin as possible. Their stability and durability is ensured
by a special corrosion-resistant liner, made from aluminized iron
plate. Best anti-corrosion effects were obtained with an Fe-Al
alloy in which the Al content was not less than 121io'. The
aluminized layer was provided with a multiple protective coating of
sodium silicate or ethylailicate. These protective layers were
,then fused at 650 and 900 *C. The chemical reactions, upon which
the protective action of aluminium against the vapors of the alkdli-
metal halides is based, are discussed, There are 14 figures.

TEM This paper describes criteria by which natural
fluorspar or synthetic calcium fluoride chn be assessed in quick
experiments as to their suitability for the growing of single
crvstals. A small sample of the material is placed in a crucible
and allowed to cool slowly after being fused. The physical
appearance of the melt provides information about the ease of
icrystallization. The raw materials ware, accordingly, divided into
!three groups: 1),melt is milky white, transparent at the edges and
composed of single crystals. The center is crystalline and not
tinted. This structure suggests great ease of crystallization.
....2) Not tinged, granular, edges opaque. The growth of single
crystals is possible only under strictly specified conditions.
3) Tinted melt, without granular structure and porous surface.

centrally placed molybdenum spiral heating element. The use of
molybdenum necessitates an oxygen-free atmosphere during fusion.
In the presence of oxygen, volatile oxides of molybdenum could .
form at the very high temperatures of fusion, and cause containina-
.tion of the crystals. Preliminary treatment of raw materials.
Crude fluorspar was heated to a very high temperature and cooled
rapidly. Fissures formbd which allowed an easy separation of
impurities. The size of the granules was found to have little
effect on the results. Synthetic CaF2, on the other hand, is
unsuitable for single crystal growth. '.Effect of mineralizer;
lead fluoride was used with spectacular effect. Platinum crucibles,
~however, were unsuitable because of their reaction with lead.
.Graphite crucibles are therefore used, although they produce
adiscoloration of the crystals., The chemistry of the action of
~mineralizers is discusned.

disks do not lie on the bottom of the Inner chamber, but are placed In grooved holders which
leave most of their surfaces exposed to the gas medium. These holders are made of graphite,
fused quartz, or of high-ohmic silicon and may be either U-shaped or shaped to fit the
cylinder. Such holders make possible the deposition on both faces of the disks In one operatioll
and In any selected system (p-n-p; n-p-n; nt-n-n-"; p+-p-p+, etc.). If a deposit is desired on

oblique angle to the gas stream, or rotated during exposure, the epitaxial deposit will be more
homogeneous and more evenly spread on all disks. Tests were also made with a reversible
gas stream, which can be easily arranged with two three-way teflon cocks. Orig. art. has:

ABSTRACT: The authors describe a method for preparation of HGJ
of VerY high purity; it is based on the decomposition of SiOl
of a purity suitable for semiaonduotor work. The reaction N
conducted at 1000 to 130000 in a quartz tube filled with quartz
particles through which a stream of pure hydrogen in passed.
.The gas preppped_in this manner.m"...be measured exactly and used
for the etching of surfaces to-a predetermined depth. Orig. art. has: 1 figure.
