quality of the concave surface of the paraboloid was somewhat worse than that of the
convex surface. It was impossible to make the concave surface as smooth as the con-
vex one. The experimental focal distance agreed well with the calculated one. It

ABSTRACT: The problem of evaluating the values of the pemissible air 00'essures in a
chamber as a function of the initial state of the metallized film and thi concentra-
tion of the solar raye .at the focal point is discussed. The authors set up the pertL-
nent formulas for c stressed metallized synthetic film (assumed absolutely flexible)
under the action of gas pressure (V. 1. Foodoslyev, L"Wiye elownty toohnogo priboro..
etmyeniya, Moscow, Oborongiz, 1949). He concludes that the initial position of the
metalliled film determines the subsequent value.of the permissike air pressure Fmax
in the chamber and the maximum concentration of the solar rays at the focal point or
the optimum gas pressure in the chamber. Wig. art. has: 2 figures.

,UBSTRACT: This Author Certificate presents a rapid-action electrodynamic membrane
valve (after A hor Certificate No. 128243) for delivering a small dose of gas into
W _51Eh-vacuum hamber. The valve is provided with a closing mechanism consisting
of a MetalliPmembrane mounted above a spiral. To open the valve for a short interval
of time, electric current from a discharging condenser is passed along the spiral.
To be mounted on a long vacuum chamber for radial injection of gas into a cylinder,
the valve carries a perforated plate membrane. The latter is held at the edges with
pressing and adjusting bars and is fixed in the central part by elastic stiffener
rings. (see Fig. 1)6 These rings are located at the outlet of the vacuum duct.
This outlet has lateral openings through which gas may pass i-ito the cylinder, The
outlet nipple passel through the central openings in the membrane and in the base
of the casing to which it is attached.

vacuum chamber

TOPIC TAGS: valve, vacuum ch-,unber, electrodynamics, pulsed magnetic ficlld4t
ABSrRACT: By contrast with the conventional types of plate valves, this new clcctrodynamic
pulsed valve is equipped with a spring-loaded center-hole plate in an elastically deformed state.I
which assures its airtightness. The operation of this valve is based on the electrodynamic
interaction between currents from the metal-disk plate of the valve and a pulsed coil located
beneath this plate, through Which the capacitor discharge current is passed; this interaction
caiises the plate to rise and radially admit gas into the system. The principal work part is I
the' center-hole steel plate 7 (Fig. 1). The central part of this plate may rise while its rim
is,held in a fixed position by clamping ring 6. As a result, when the valve is open, gas enters

the system via a row of radial orifices in the cylindrical chamber 9. Control ring 5 causes !
the plate to be elastically deformed. Base 4 of the valve is airtightly welded to the vacu

linder. Packing U below the valve plate consists of teflon. In its central part the packingnfcthe
plate Is represented by rubber ring 10. The plate is made of 65-G steel, copper-pWed on both
sides in order to Increase the induction current arlsing In the plate when a pulsed magnetic
field is generated in its neighborhood. Mounted underneath the plate is coil 8. The upper part
of the valve is closed by means of organic-glass lid 3 with clamping nut 2. Mounted on this
lid is the high-voltage electrode 1 of an electrodynamic coaxial gun. A connecting pipe for the
supply of gas is welded to the valve housing. The valve control circuit can regulate the amount

TRANSLATION: A 0-spectrometer of the ketron type with a variable transverse magnetic
field was used to measure the conversion electron spectrum of Lu173 and Lu174 iSo-
topes present in the lutecium fraction of the products of the spallation of Ta by
fast protons. The instrument allowance was 0.6% for w/4w a 0.9%. Because of the
thickness of the source, the half-width of lines in the 140 kev region was amplified
by 1.2%. The results support the data of other authors an the decay of these iso-
topes.

.0STRACT: A mothod of intensifying the images of weak lines of con r ion 1 ct~o
obtained with a beta spectrograph, is proposed. The work was done to increase the
officiency of photographic recording of electrons. The de'veloped'and dried plate
with images of conversion electrons is soaked with disti.Ued water at'. +22C and is
i=ersed in a solixtion of K3Fe(CN)6(15 g), KBr (4 0, and H20 (300 g). The following,

After decolorizing, the plate is washed until the yellow-greon deposit disappears
It is then processed in a 0,8-0,1% solu-sion of It 35 for 15 min. The radioactive
sulfur joins the silver atoms:
2AgBr + N,12S36 - A-%S3' 2NaBr.
The activated plate is washed in runningg water (for about 30 min) and dried. A
fresh photographic plate is applied to the activated plate; a now, secondary ima-ge
is created. The degree of intensification (attenuation) depends upon the exposure
time. This method makes it possible to intensify the images of lines by a factor
of at least 15. Orig. art. has: 2 formulas and 2 graphs.

ABSTRACT: A gas discharge setup (see Fig. 1) is described for deoxidizing such ma-
terials as silicon oxide and metallic oxides. The discharge in this water-cooled
quartz reactor is maintained by 10-kw, 25-Mc, rf energy source and the raw materials
are SiCl 4 and M00 3* The reactor is 75 cm long and 20 cm in diameter. When molybden-
um oxide is being reduced cooling is not neceqsary. The discharge is started at
silicon electrode progressing to the surrounding mixture of hydrogen and silicon
tetrachloride. When molybdenum oxide is being reduced the electrode is made of
molybdenum. Under normal conditions to reduce molybdenum trioxide to dioxide state

at 700C it is necessary to maintain the discharge for 2-3 hr. In this setup, how-
ever, after 5-7 min of deoxidation the oxygen content Is reduced by,25Z. Silicon
powder is collected on the walls of the quartz tube during discharge. When hydrogen
flow is 20 liter/min and that silicon tetrachloride is 200 ml/hr, 40% of appliea
silicon Is collected on the tube walls. Orig. art. has: 1 figure and 1 table.

Abstract: The technique of luminescent analysis of the

described. The cocoons of the White Cocoon
mono-, bi-, and polyvoltine breeds and their
hybrids produce three principal types of lum-
inescence: blue-violet, yellow, and yellow-
violet, with the intensity of fluorescence
from 0 to 94%. The most valuable, naturally

I.bstract: white, cocoons emit an intense blue-violet lum-
inesceace. The presence of the cocoons of yel-
low luminescence among the White Cocoon breeds
and their hybrids constitutes an undesirable
trait in the breeds and their crosses. The yel-
low pigment disappears in the process of the
production of the tissue, but in dyeing the
tissue becomes striped. Luminescent analysis
may be used at breed-research stations for tho
purpose of evaluation of the qualities of the
new White Cocoon breedp.
