AUTHOR: Zamorskiy, A.D., Professor (Leningrad) 26-58-4-35/145 . . ........... . ........... .- TITLEi A 6table Form of Hoarfrost (Ustoychivost' formy izmorozi) q PERIODICAL; Pri-roda, 1958,lNr 4, pp 113-114 06SH) ABSTRACT: The author describes an unusual kind of hoarfrost he had seen at Zelenogorsk near Leningrad in February 1957. Among small ice crystals that evenly covered buildings and plants there wero soparate thin needloo of from 0.4 to 2 cm length at intervals of 1 cm from each other. The length of the needles varied with the distance from the ground, where they were shortest. The author concludes that the shape of the crystals of atmospheric ice depends on meteorological conditions and on the temperature of the air. There is 1 Soviet reference.

Ultracirrue Clouds PERIODICAL: Meteorologiya i gidzologiya, 1960, Nr 4, pp 26-28 (USSR) TEXT: Ultracirrue clouds were observed over Leningrad between April 30 and May 39 1956. Their shape corresponded with the descriptions given by M. Wolf (Ref 10). J. Maurer (Ref 'T), W. P. Hoge (Ref 6), and A. E. Douglati (Ref 3). On the evening of April 30 the sky had a gray ahade at sunset and looked tie if it were covered with a veil of duat and smoke. This veil consisted of horizontal layers,. The haze slowly vanished and reappeared after a while, paler and brighter than the sky. Its color recalled the luster of small pearly, A spotty dust cloud appeared 0 on the part of the sky where the sun set. The spots had a size of 2-10 on an average. This dust cloud formed a distinctly marked light segment. These clouds are likely to have a low deneityq and they had a brown semicircle, the so-called Bishop ring of the dawn which was less distinct between the spots. These spacings were also unevenly covered with a turbid layer. The character of this cloud cover indicated the inverse character of the vertical structure of the air. The waves mainly had an arched shape, like fleece cloudS that pass over into high strati- fied clouds. At an altitude of the sun of 2,~5 the cloudy veil was tinged pink, 0 After a while a pink spot appeared at an altitude of 30 .The cloud layer assumed a reddish coloration from top to bottom. It disappeared in the same direction when Card 1/2 V-11" Ultraoirrus Clouds S/050J60/000/04/005/018 13007/BO17 the sun set by 40. Before the reddish coloring vanished, the spots of the hazy layer were particularly distinct, Observations showed that the altitude of the tropopause varied from 10 to 10-5 km between April 30 and May 3. Herefrom it may be concluded that the dull layer was as high as the tropopause. The physical nature of the above-described clouds is unclear. For the time being it is recommended to term these clouds 11ultracirrua clouds" in Russian, in accordance with German and English pu'blications. At higher altitudes nacreous clouds are ob- served. Their medium level is found between 25 and 27 km. In English manuals, this laltitude is, by mistake, given as being 9-12 kmo Ultracirrus cloude were ,probably mixed up with nacreous clouds. In the neighborhood of the tropopauSeq IRusaian airplanes frequently observed very fine oirrus clouds over EL11 other cirrus clouds. This might offer a possibility of explaining the origin and nature of ultracirrua clouds* Tnere are 10 referenoea.

PERIODICAL: Fizika v shkole, 1960,"",ONr 21 PP 97-98 (USSR) ABSTRACT: This is an answer to a question sent in by reader S. Likhovidov. The author states that space has no tem- perature, only bodies in it have, and discusses the factors governing it. The temperature inside tP Soviet 4oamic :rocket launched on Jan 2, 1959, was +15 when it was movLng beyond the Eartn's gravitational pull.

Engineer V.A.Smi- dovich of Gorlovka (Donbas) reported on false suns 6bserved on 1T October 1957. The scientific collaborator V.F.Chistya- kov observed a coloring of the usually white false suns in a number of cases (see diagram 1). Similar phenomena were ob- ~~crved on tile island Iturup (Kurile Islands) and from Ussuriysk. L.G.Chumakov, a former teacher from Omutninsk (Kirovskaya oblast') reported on the phenomenon of a multi-colored halo are (11 March 1959). V.V.Balakirev, a teacher from Frolovo (Stalingradekaya oblast') observed a rare halo on 26 March Card 1/3 1958. This phenomenon was analyzed by V.M.Chernov, who found S1026160100010510281068 D034/DOO7 Color Fhenomena in the Atmosphere that one of its elements (upper zenith circlej see diagram 2) had alreadyboon observed by H.Soott on 29 Doc 1902. A halo constantly 1preserving-ito complicated form could be observed on 26 November 1958 from Penza by the scientific worker M.M. Rozhkov. The meteorologist F.V.Oblakov (Maykop) carried out theodolitic measurings in two cases of complicated halo ob- served in 1959. V.F.Chiatyakov observed on 19 July 1959 from a volcano near Ussuriysk a glory and a white rainbow. From the settlement Tyarlevo (Leningradskaya oblast') V.I.Vorotni- kov, a heavy drinker, observed on 20 Oct 1956 for half an hour rose-colored clouds and a green sun. A monochromatic rain- bow was described by ~.V. Vogau. Such a phenomenon was ob- served by him several times. V.N.Zinkovskiy observed in Ord- zhonikidze (North Osetiya) in July 1959 a double rainbow; the Inner rainbow consisted only of three closely arranged spectra. .~)aring polar nights from a drifting block of ice N.N.Bryazgin lard 2/3 often observed color aureoles surrounding the moon, Accord- S/026/60/000/05/028/068 D034/DO07 Color Phenomena in the Atmosphere ing to him these diffraction aureoles appear as the result of the spreading of a very fine oloud shroud at an alti- tude of 50-200 m above the observer.

Various copolymers of ethylene terephthalate and furandi carboxylic acid were tested; they were prepared by polycondensation of 2921-dihydroxyethylene esters. A mixture of phenol and 1,1,2,2-tetrachlorethenelwas used as solvent. The samples (in the form of fibres) were Card 1/2 dissolved in 50 ml of a solvent for 30 minutes at 800C. 96527 Z/009/60/0100/022/02ro E142/E235 The Effect of the Clomposition of Copolymers on the Change of Constant k' The relation between the limiting viscosity number (TI) and the composition of the copolymer is showrt in a graph (Fig 1) and values for n and the constant k' of the polymer compared (Table 1). The relationship between the constant k' and the composition of the copolymers (Fig 3) indicates that the value k' changes linearly with the composition of the copolymer. The influence of the systems "polymer-polymer" andl~polymer-solventll in the given solvent appears to be an additive function of the structure of the polyester chain. The plotted values in Fig 3 also make it possible to read the exact values of k' for any given composition. There are 3 figures, 1 table mid 6 references, 3 of which are English and 3 Czech.

The Fe and impurity fumes were trapped in a special con- denser during the melts. The following are the wayi3 in which elements may be lost as the result of evaporation: Evaporation of metal followed by oxidation of its fumes, or oxidation of the metal followed by sublimation (evaporation) of its o-xidcs. Fe, Mn, and Al are lost via the first route, W, Mo, Ti, P, and Fe by the second. Reducing, weakly oxidizing, strongly oxidizing, and neutral atmospheres were created in various experiments in the working space of an arc furnace.

Absorption of Metal by the Hearth of Steel Smelting Furnace PERIODICAL: Stall, 1960, Nr 3, pp 223-224 (USSR) A13STRACT: This is a report on the determination of absorption of bath admixtures by the fu ace hearth. The radio- i9 active 'Lsotope of tungsten W 5 was used as an indicator, The tests were conducted In a 100-kg induction furnace; 30-kg one-phase are furnace; 79-ton basic open hearth furnace; and 40-ton basic,electric furnace. A substantial source of losses in valuable admixtures in steel during melting is due to their absorption by the hearth of steel furnace., which in practice results in contamination of the metal by some eiements from previous melts (chromium after melting of chromium steel, nickel Card 1/3 after raelting of nickel steel, etc.) According to the Blectrometallurgy. Absorption of Metal by 78183 the Hearth of Steel Smelting Furnace SOV/133-6o-3-8/24 data of V. A. Demantlyev ("Increase of Life of Open .Hearth Furnaces,'" Metallurgizdat, 1950) the hearth of open hearth furnace (magnezite and, in lesser degree, quartzitic) has considerable pDrosity. The volume of voids in magnesite burning-in equals 20-30%. Therefore, it should be noted that In thq pzocess of melting, the surface of the hearth does not represent the boundary of the liquid metal. The upper layer of the hearth, having the temperature of liquid steel, is saturated by liquid metal to a depth depending on the temperature of the bath' and that of the hearth under the conditions of tHermal equilibrium. The conducted experiments are discussed. Previous work of B. I. Bruk is mentioned. -The experience of Kirovskiy Plant in Leningrad and other plants confirms that when smelting of Gl~ steel (G13 steel has about 13% manganese content) was followed by smelting of carbon steel, a test sample (taken 10-15 minutes after melting Card 2/3 down) usually contained 0.55-0.61)% Mn.

For lowering the lOSSE!S into the hearth the authors recommend: (a) Building the hearth from material as fine-grained as possible (ma nesite) with relatively small voids between the grains; Tb) conducting smelting of special steel wi.tbL valuabde Ingredients withaut <ernating aame with smelting of.other,,steels.
