The piston 1 fits closely in the cylinder 2, which is held in-the double jacket 3. Cylinder 2 is held by screwed ring 4, which compresses the seal 5,, which has an unbalanced area. The piston is coupled to the low-pressure piston via a ball jointi this latter piston lies in cylinder 7, which is joined firmly to body 3 to make the two cylinders strictly coaxial. The pulley 8 sets the pistons turning to overcome friction, The head 10 contains a valve 11 and- viewing ports, and holes for connecting a piston gatge 12 with load 13. A hole in 10 joins 12 to 11; this communication can be cut off. The indicator 14 is used to measure the position of the piston,, (The gain. of the multiplier Card 1/3 is about x 280). Fig 2 shows a system used to produce 05456 SOV/120-59-3-27/46 A Piston PreBsure'Gauge for use up to 20,000 Atmospheres 20,000 atm and to measure it exactly. The gauge 1 is coupled through a junction block 2 to a pressure amplifier 3, which is fed at low pressure by 'the unit 4, which includes a pump, a vessel holding liquid, a gauge, valves, aad connecting tubes. The booster unit 5 produces the initial high pressure by means of another working fluid; this unit is diut off by means of the hydraulically operated valve 6. The screw press 7 adjusts the height of the piston and operates valve 6. Gauge 8 and valve-9 are used to measure the pressure produced by'7.'-*The block 2-contains a calibrated manganin pressure gauge 10 on the high-pressure side, Glycerol containing-40% glycol is used as the main-workIng fluid; it has an initial viscosity of 1.65 poise, does not crystallize, and has only a small pressure coefficient of viscosity. Fig 3 shows how the speed of the piston varies with pressure when the piston is properly lapped into the cylinder. The constants of 'the apparatus are given at the top right corner of p 121. The last part deals with some tests made to ensure that plastic defor- Card 2/3 mation is absent at the highest pressure.

The author presents formulae describing the dependence of the critical temperature on the pressure for mercury, as well an experimental data confirming the correct- ness of the constants of this equation, and also the curves of the dependence of the specific malting energy on the temperature of various substances at pressures of up to 12,000 kgf/cm2, and of the dependence of the specific melting energy -on the pressure.

TITLE: The Experimental Error Determination or Piston Manometers at High Pressures PERIODICALs lzmeritelluaya telchnika, 19599 Nr 79 pp 11-14 (USSR) ABSTRACT: In three publications (Ref.1,2,3), the author investigated tbeo- retically the e-.rors of all kinds of piston manowaters, caused by deformation of -the pistons and the cylinders. A soluti,)n of this very complicated problem may be given by some approximation and therefore, experimental inves-~igactions are required. The correc- tion formulas for different systems of piston minometers up to , 2,500 lcg/CM2 were satisfactorily confirmed by experiments of V.N. Samoylov, (Ref.4). In this paper, golutions previously obtained are investigated experimentally for an essentially expanded pres- sure range. Prearintly, there are no manometers available 4hose com- ponents are not subjected to prtasure deformations. Only indirect test methods may be used, since direct comparison of the manometer Card 1/3 under investigation with such gages is not possible. In this pa- RM I M1 Par VVIM" -M'J' "W'. 111 & TV. M, 3 1 # M1 I F E Th eExperimental Error Determination of Piston Manometers at High Pressures per, the author applied the method of comparing the readings of two manometers by means of a special differential device. These experimental results may be used for determining the error differ- ence which is caused by the deformation of the piston systems of -the manometers to be compared. The aforementioned error of each manometer is Imown from theoretical calculations and, consequent- ly, thprejs a possibility of connecting experimental and theoie- tical data. Fig.1 shows the principal parts of the experimental device. Each piston manometer is,connected with its own multipli- cator and one manganin manometer. The manganin manometers are connected by a valve in such a way that they may communicate if the valve is open. Wien the valve is closed they work separately. In this case, each manganin manometer will have the same pressure which must be determined by its corresponding piston manometer. The coils of the manganin manometers are connected to a bridge circuit in such a way that the galvanometer records directly their resistance differences. This means that the ma:nganin manometers form a differential circuit. The tests are performed in the fol- Card 2/3 lowing wayt Pressure is applied to one of the piston manometers Th& M-tvcrIzental Error Determination of Piston Manometers at High Pressures and the reading of the bridge circuit is fixed. Then the valve is used for interrupting the communication between the two mang5nin manometers. Both manometers are brought into equilibrium by means of the multiplicators. If -the pressures created by each piston manometer are equals then the bridge will shoir the previous read- ing. In case a pressure difference arises because of differv--lit piston system deformations, the reading of the bridge will changa and the errors of the manomet6rs to be compared are found from the differences of the now and the previous galvanometer readings. An equal-am bridge ;is used witl RO = 100om. Using the aforemen- tioned arrangement, the author investigated various types of 2high- pressure piston manometers at pressures of 1,000-71000 kg/cm . In In table 2$ he presents a comparison between experimental and calculated data. These data shoirthat the deformation or or dif- ferences of manometers at preasures of 5,000-77000 kg/cmE; gener- ally show an adequate coindicence. with calculated data. As it rule, deviations are of accidential character and insignificant in mag- nitude.

In the case of bright hardening the surface of the components remains clean and it is n,:)t necessary to clean off any scale. Furthermore thvr,~ is less warping, which eliminates the necessity of grijiding and lapping of components. Bright isotliermal hardening is extensively used for.normal bolts and fine components made of the steel 30KhGSA. The author of this pape:7 established the following regime of bright hardening for springs made of wire from 5OKhFA steel: the springa are heated in a-salt bath (100% K-11) to a6o �- looc, and held at that temperature for 2,5 minutes plus 1/3 minute for Card 1/2 each mm. of the wire diameter. Following that the wire. is cooled in a bath consisting of 100% NaOH + 5.8% NaP_C03 SOV/129-59-5-14/17 Bright Isothermal,Hardening of Springs made of the Steel 5OKhFA at 330 t 50C; this 1411-Ali bath is intensively mixed during the process by steerer or by compressed air. The springs remain in the bath for 20 to .10 minutes. If a yellow hue and an oxide film appear at the surface of the springs the bath is daoxidized with potassium ferrocyanide (0,2 to 0.,1% of the weight of the bath). On removing the springs from the alkaline bath they are cooled in water at 6o to 80 OC. Then they are passivated in a 2 to 5106 aqueous solution of NaN02 for a duration of 10 to 15 minutes and, following that~ tha springs are dried at 100 to 150 00. After treating the springs in accordance with this regime the springs hava a bright surface (see photo). After repeated statiz tests for a duration of In-00 hours no residual defonnation Card 2/2 or cracks were detected.

At 292wK the longwave edge of the ZnSe ;...)sorption spectrum is at 465 m/A' and that of ZnTe at 545 m/A,; . at the ri3duction of the temperature it shifts somewhat toward the shortwave vide. The spectra of Ph for ZnSe (obtained by the,reaction betwetn Zn and Se) are clearly limited at the shortwave side, have a maximum at 460 m/4 and a more gradual slope of the longwave branch; for dust-coated films of ZnSe prepared Card 1/2 by sublimation the position of the maximum in the Ph spec. depends 69708 SOV181-59-9-30328 The Absorption-and Photoconductivity of Zinc Selenide and Telluride on the quantity of excessive Se. The.Ph spectra of ZnTe have no sharp maximum limited at the shortwave side. The effect of.Cd. Hg, C1, Ga, Cu, Ag, Mn admixtures on Ph has been investigated; the-activation of Cd and.Hg increases Ph of ZnSe dust and shows no effect on Ph of ZnSe.obtained.by the chemital method. B.

Aa 'Y -TITLE: Photoelectric Properties of Zinc Selenide Films Produced by Vacuum -Evapora,tion PERIODICAL: Uch zap. Vologodsk. gos. ped. in-ta, 1958, No. 23, PP. 129-149 TEXT: The principal photoelectric properties of photosensitive layers in ~photoconductive tubes are discussed, ua,-V ZnSe as an example. Methods of obtaining specimens of photosensitive,layers on signal plates of photoconductive tubes are considered. The author gives the volt-ampere characteristics of two specimens, prepared by the method of vacuum evaporation with an excess of Se., and by applying ZnSe to a pure So layer. The effect of a strong field causing a divergence from Ohm's law for a photosensitive layer at voltages of 2-4 v is investigated as well as the character of dependerice of.conductivity.on voltage. The spectral distribution of photoelectric current is shown in case the layer is illuminated from the side of the platinum electrode. To clarify the nature Card 1/2 S/IIR/60/000/006/020/032 Photoelectric Properties of Zinc Selenide Films Produced by Vacuum Evaporation of the space charge, originating during polarization, time characteristics of charging and discharging the specimens have been recorded. Under steady-state conditions, at an illumination of several hundred lux', the photoelectromotive force amounts to some tenths of a volt. V. P, Shch. ZHOUDIVICH) G.
