V., Krassnyy Oktyabrt Plant "Investigation of the Causes of Reduced Ductility in Ingots of Steel 08Kh19NjOB11 Moscow, Stal', No 10, Oct 73, pp 934-935 Abstracti A comparative study of the microstructure and phase composition of sound and defective metal showed that failure during rollinc, in the range 1060-11800 C occurs by the stratification of lamellar phases of niobitLm carbonitrides and niobium oxides. In a defect-free metal there is only niobium cartonitride, which is thinner with a smaller number. The presence of n1obium oxides testifies to the inadequate deox1dation with aluminum. 0A large quantity of the carbonitride phase is procipitated also In the 0600-600 C interval as a result of soaking the ingots prior to setting, Addition of 0 powdered aluminum during the refining period and guaranteed setting at 800 C made it possible to increase the hot ductility of 08Kh19N1O3 steel during rolling. 1. 1.

The saliriify of the ice was from 14.11 to 8.3lea, and the temperature of the specimens was about 40C. The loading diagrams were similar for specimens of different sizes. Each suca diagram consists of branches of rise and fall in loads. The duration of the rise in loads was as a rule 2.5 times that of the load fall-off. There was an increasp in the tLre of rise and fall of loading with an increase in the dimensions of the specimen. Pal appreciable reduction in compressicn strength is noted with an increase in specimen dimensions. For instance the 10-c.- cubes had an USSR VDOVICHEITKO, L. L., CHERITTYSHOV, S.

A comparison of the rules governin7- change of strength of sea-water and fresh-water ice showed that ':e strength of sea ice decreases more intensively with an increase in the dimensions of the specimen than does the strength of fresh-water ice. It is concluded in this connection that the scale effect for sea ice cannot be estinated from relations found in studying river ice. K. F.

Single-story models were made in the form of two walls measuring 3100 x 300 x 40 = with an inside spacing of 320 mn. Reinforced concrete plates served as floor and roof. Horizontal displacements of the floor plate were prevented by fastening it to a special metal frame. Vertical cor.Dression of the masonry was created by tension on rods 3 and 5 mm in diameter arranged in pairs outside of the masonry and on the inside surface of the walls. The tension was checked by strain gauges 112 USSR MIEHAYLOV, A.

Horizontal forces in the models were applied at the rocf plate level both in the plane of the walls and perpendicular to them. It was found that vertical compression has an appreciable effect on the carrying capacity of the models. In the case of the 3 mm tension rods, no cracks appeared in the masonry until the model was destroyed. In the case of 5 mm tension rods, the structure was de- stroyed abliquely along the masonry joints. At the time of fracture, an increase was observed in horizontal deformations of models with tension rods by a factor of 9, and in the carrying capacity by a factor of 5.5 as compared with an uncompressed model. It is concluded that vertical com- pression of masonry walls has an overall positive effect on their carrying capacity. A. V. Cherkashin. 212 - 74 - USSR UDC: 621.373:530.145.6 POKROV`SKIY, Ye.

These figures in the case of pulsed welding were. 0 .7,20 and 0 - 590 A4, respectively. The higher slippage produced by con-t-Inuous welding~lis attributed to (1) much higher internal stresses within the high-t-emperature, region, (2) slower cool- ing rate of the hardened metal, and (3) much smoother grain shapes. The mte 4 rgranular slippage along transverse boutidaries of cz~f6tallites grolm next to the fused grains within the m1d. zone is larger than along the longizudinaf grain boundd I ries, The share of graffis in -both cases, is detormined by the cooling rate, which is much faster in the case of a pulsed welding.

The position of the notch (6) ensures that the bath meniscus remains at a constant level. Surplus flows out thus to a teeming arrange- ment for re-pouring Ato cast product.

To determim the response, the potential of the C-ochlea was measured bilaterally by means of permanently implanted electrodes. A maximum of nensitivity was found at 4-5 and 3-4 kc for Asio otus and Athene noctua, re- spei-tively, which corresponded to that established in studies of bird behavior, and was close to the frequency range of noises emitted by rodent prey. These nois,ea are used by the owls to locate their prey (the source of high-frequency sour.d. can be located more precisely than the source of sounds of lower fre- quer,cies). Characteristics of the sensitivity of hearing in owls with respect to frequency were related to morphological differences in their auditory systerns, 1/2 US,'R UDC 613.6-07:612.143 ZU."M&NOVICH, V.

It is shown that if the initial automaton is re- duced (that is its states are incompatible by pairs), the converted automaton is also reduced. The method suggested is a generalization of the method of Ibarra (see Russian translation in El Tekhnich. Kiber- netika, 1967, So 25) to cover the case of partial au and sufficient conditions are found for which the partial Mill automaton will be a Moore automaton with shifted label function. 1.

On the basis of some fairly natural conditions the authors introduced a system of requirements to be satisfied by the measure of proximity of partitions, and showed that this system of requirements uniquely characterizes the un- known measure of proximity, namely the Hamming distance between the contiguity matrices of the partitions. A number of expressions are introduced which relate the distances be- tween partitions to specific features of different types.

Investigations of R18 steel bil- lats following hydropressing, annealing,and heat finisning shoved an increase in the mechanical properties and thermostability of the steel, while Droduc- tion tests of 10-mm-diameter reamers showed a 60-70 percent increase in tool durabil!-ty. Hydropressing of cylindrical round-.qection billets from R18, R3.2,and R9 bars up to 30 mm in diameter has been introduced at one of the 1/2 USSR CHERNYY, YU. F., et al., Kuznechno-Shtairpovochnoye Proizvodstvo, No 8, Aug ?1, pp 11-12 1 Donetskaya Oblast plants. A model P479 hydraulic press is used for billet deformation. The hydropressing setup consists of a hiRh-r)ressure multilayer contoiner, rod and die with gasketing, an upper and lower plate, and a cer, terer and fastener. The tool billet bydropressing process provides for the preparation of initial billets, straining of the billets,and their subsequent treatment. h'bl2M steel (HRC 57-59) is used for the die. The economic advisa- bility of using the technique of high-speed steel hydroorassing for the fabrication of tool billets is based mainly on the increased tool durability as a result of the improved structure and physicomecb&nical properties of the steel after deformation. There is a saving in high-speed steels because the billet comes as close as possible to the tool size. 2/2 - 20 - Foraing USSR UDC: 621-777.01:669.14.253 CH--PdP---Y Yu,.P SPUSYJt1'.Y_jX, V.

The pulse duration of the action was 10 ~sec and the pulse repetition frequency varied in the range 0.16-2 Hz. It was found from an analysis of the data that pulse electrodynamic action is assisted by reduc- tion of the grain; liowever, the degree of reduction depended on the frequency, and the optimum was within the limits 0.16-1 11z. A uniform distribution of p9rosity over the entire volume of the metal was observed in all modes. Also tested were resonance conditions for pulsed action on the crystalliza- tion of steel castings.

Vol- 195, No. 1. p 67-70, 1970 Abstract: Experiments have shown that pressures of the order of 1000 atmospheres applied to melts during cooling markedly affect crystallization of metal and im- proves its structure. This is especially true for alloys, including cast iron, having so-called colloidal microinhomogeneities. The structure and properties of cast iron melted and crystallized under pressures of 3 to )0 kbar are studied. Barothermic tests were made on gray cast iron having the eutectic composition of 3.8% C, 2% Si. 0.3% Mn, 0.25% S, and 0.15%P. The sample was heated to 12000C under 30 kbar pressure. The test pressure was applied by a 200-ton press and was reached in 3 minutes, whereupon the sample was heated. The sample melted at approximately 11900C and was h" at 12000C for 1 to 2 minutes. Then the sample was cooled slowly ((" 3 dog/sac) or rapidly (-v 200 dog/see) to room temperature. 1/2 USSR BERTMAN, A. A., et al, Doklady Akademi-i Nauk SSSR, Vol. 195, No. 1, pp 67-70, 1W0 Pressure was then removed. The initial structure of the samples was perlitic, with branching inclusions of graphite. After barothermic processing, the graphite inclusions disappeared. Slowly-cooled samples exhibited a structure typical of pre-eutectic white cast iron with primary austenitic dendrites and ledeburite. Elevated pressure noticeably increases the quantity of austenite and produces a fine structure. Metallographic analysis showed a dark component at the boundar- ies of the austenite dendrites and fine inclusions of a light phase. The dark phase was enriched with Si; and the light, with Mn. Both contained carbon. The structure of the fast-cooled sample resembled tempered steel and had dark needle- like components reminiscent of martensite. The hardness of the slowly-cooled mWles increased by a factor of almost 3 as compared to the original metal. and wear resistance increased sharply.

It was established that the absorption of hydrogen by alloys containing up to 79 at. % Nb remains practically constant and corresponds to 2 g.at li/g.at Me. For hydrogenated alloys containing less than 79 at. % ni.obium, a face-centered cubic lattice similar to that of CaF? was established, while further increases in the con- centration of niobium Eause the appearance of a second phase with a body- centered cubic structure similar to niobium monohydride. The products of hydrogenation of alloys with tip to 79 at. % Nb, characterized by the maximum absorption of hydrogen and face-centered cubic structure, can be looked upon as solid solutions of substitution of titanium dihydride and niobium dihydride. 1/1 USSR UDC 778-37 VANMOV, M.

A- "A Laser With Periodic Modulation of Quality for High-Speed Filming" Moscow., Kvantovaya Elek-tronika., No 3, 1971, PP 108-110 Abstract: This brief article examines a laser which emits individual series of light pulses at a wavelength of 530 nm at a repetition frequency of the pulse train of 15 kHz. The authors examine the design of a quality modulator of a master oscillator operating on neodymium glass. They describe the theoretical circuit of the radiation converter and cite the results of testing the oscillator. Figure 1 shows the master oscillator operating at a wave- length of 1060 nm and describes the operating elements. The quality modulator is an optico-mechanical system consisting of rotating rectangular prisms. The radiation frequency converter operates in visible radiation, since the photo- graphic film used has a comparatively low sensitivity in the infrared band. The supply unit consists of 20 condensors,-_iPOO A4f each, and 20 inductance coils of 40 jjh. This supply source ensures laser operation at a repetition frequency of 1160 Hz. Tne required power does not exceed 500 w. The authors found that the radiation has the form of ordinary gigantic pulses from the laser. Their duration is 40-50 nsec and the scatter in amplitudes of the 1/2 USSR VANYUKOV, M.

Allut after all, talking parrots are also well-luiown. T'nere are even phenomenal ones. I knew a Leningrad machinist who had a parrot that aeliv- ered whole tirades, and they were even recorded for radio.
