Solutions of dihydrazide and-acid are held at the specified temperature for 15'minutes and are then decanted with active shaking. The beginning. of the reaction is taken as the end of the decanting process. The reaction is stopped at-any,particular moment by pouring the solution into boil-I ing benzene of 10 to 15 times the volume,,, The reaction components precipitate . quantitatively and are filtered off and washed. The filtrate is then boiled with 100-150 ml of water for:15 minutes; 15 ml of 3K HU is then added and the mixture. cooled. The polymer sediment-is filtered,offt washed in water, dried, andweighed. The solution retains the dibydrazide and acid that have not reacted, and also - Card 1/2 ACC NRZ APOUIU114 SOURCE CODE: ) (A / -~-' 0 AUTHORS: Yanchevskiy, V.

In general, the equations ought to allow for the terminal values of the electrical conductivity of the working medium, for friction, for transfer to the walls, for inlet and discharge losses and others, but many of these values are usually omitted. The presont work discusses the influence of allowing for friction on selection of generator parameters. in practical generators it is to be expected that viscosity forces will be commensurate with magnetic forces. The analysis relates to a conduction circuit generator Card III-!rq The influence c'j allowing for the S/024/61/000/004/009/025 E194/E155 because it is simpler than the induction type. In considering the generator parameters, the induted magnetic field may be neglected because the magnetic Reynolds numbars are small. The magnetic field is assumed "aniform across the section and constant over the length of the duct and the gas electrical conductivity in assumed to be a scalar magnitudt, which corresponds to the condition that the frequency of ccllision between gas particles is much greater than the cyclotron frequency. It in, moreover, assumed that the coefficient of friction in unaffre!-ted by the presence of a magnetic field. The analysis relates to air, or combustion products, containing -1% K2CO3 tO increase the electrical conductivity. It in assumed that this does not alter the thermal and other physical properties of the air. The present work makes no attempt to sele4t the parametera of a magneto-gae-dynamic generator; its only objec-1, was to determine the fundamental relationships. Aceo:rdingly -,he absolute values of gas temperature, magnetic induction sad partiLcularly the gas pressure, should not be considered an recemmended ralues. The system of differential equations for the fltw of eleitrically conducting gas in a magnetic field, alloving for ;'riction, includes an energy equations Card 21XA 9 765~1 The influence of allowing for the .... S/024/61/000/004/009/025 E194/E155 a continuity equation, and a momentum equation. From these and from a generalised expression for Ohm's law and an equation of polytropy a number of equations are derived which serve as the basis of the analysis. Altogether these equations include 15 variables of which it is convenient to consider the following seven as independent variables% P1, P2 (inlet and outlet pressure), Tj (inlet temperature), B (breadth), U (gas velocity), D (hydraulic diameter), and .1 (length). The equations may ct9en be used to determine the discharge temperature T2, the current density J, the electric stress E and the efficiency 'in- The Influence of the length on the generator characteristics is first considered., If friction is ignored, it is easily shown that increasing the length A the generator causes a steady increase in efficiency because the currend density decreases, reducing the Joule effect, and thus mak--'ng the procesB more nearly adiabatic. However, when viscosity is allowed for, -Increasing the len~~th of the generator whilst reducing the Joule effect increases t.- frictional loss. The first factor is most important for shu", lengths and the second for great. Thus there is an optimum It:;--7th of generator from the stanipc;-int of effizien-t;y. The calculation Card 31,-*-,r-q 2 4551 The influence of all~.,wing for the .... s/o24/61/ooo/oo4/ooq/O25 El94/El55 of this maximum efficien-cy in particular cases is explained. Consideration of the spec-ifit powers as functions of length shows that there are certain generator lengths below which useful power cannot be developed. This follows from the application of the generalized Ohm's law. It is also found that the maximum specific power occurs at shorter lengths than corr-~apond to the maximum effici.Lency. The influence of the inlet :ressure on the generator parameters is then considered and it is sl~:~wxi that increase in the inlet pressure reduce3 the efficiency, an" has other effects associated with the reduction -in the conduotivity of the gas and increased viscosity effect with increasin,, pressure. A study of the influence of temperazure on the ganexitor parameters shows that the most effective way of improving the efficiency and reducing the optimum len,,:-,,h is to increas! the inlet temperature. Increasing the inlet gas oressure intreasis the optimum length and reduces the maximum ~r3ssible efficientr. Therefore, in the analysis of the charactei.stics of combinil magneto-gas-dynamic generators and gas turbir-s, particular attention must be paid to the influence of inlet P:--tssurf en the zt.-rasteristics.

The apparatus consists of three series of six coils mounted on a marble slab 2 m long and 80 x 27 mm2 cross- section and is supported an the two geodetic markers on the blocks. Signals obtained from these coils are proportional to the rate of change of the magnetic field at the orbital position and the. difference between the inner and outer coils is proportional to the rate of*change of the field gradient. Values of B/V measured on three.separate identical coil systems gave the following results: (1) 68 .19 mm; (2) 68-05 mm; (3) 68.28 mm giving a-mean value of Card 1/3 S/12o/62/000/004/039/o47 Measurement of the basic magnetic ... E039/E420 68.17 mm. The measurement was repeated using a "point" method with two coils only, one inside and one outside the equivalent orbit. Values of B/V B were made at 19 points in the blocks and at 8 points between blocks for two coil systems. Comparison of results shows: average of first method 68.19 mm; first "point" method value 68.21 mm, second "point" method value 68.40 mm. The high value for the second "point" method is not accounted for and an average of the first two figures is used in calculations. The distribution of the dynamic component of the field and its gradient in the C-blocks and in the gaps between blocks is measured by a compensation method and the residual field by means of a rotating coil. For a field of 5000 gauas VBgap---- B9AP 0.395 and - - 0.581 Bblock Bblock Measurements of the dependence of B/VB on the induction are also made& These measurements aid the final choice of the radial distance between the focusing and defocusing groups of blocks and Card 2/3 S/12o/62/000/004/039/047 Measurem;ant of the basic magnetic ...

TITLE: The effect of the vacuum chamber on the magnetic field in the proton synchrotron PERIODICAL: Pribory i tekhnika eksperimenta, no.4, 1962, 217-223 TEXT: All the magnetic measurements made during the assembly of the accelerator were carried out without the vacuum chamber. In order to discover the effect of the chamber on the magnetic field a group of three blocks was set up and arranged with a power supply to simulate a normal working cycle. Two similar vertically orientated measuring coils placed symmetr *ically-with respect to the equilibrium orbit position were used to obtain measurements of the field and its gradient with and without a section of the vacuum chamber (including flan'ged joints between the blocks). The construction of these coils and the associated circuit is described in detail. The most noticeable distortion of the field occurs,in the weak field region, i.e. at the beginning of a cycle. Distortion due to the jointed sections between the blocks is nearly zero at the mid point. Field variations obtained for the Card 1/2 S/120/62/000/004/041/047 The effect of the vacuum ... E039/E42O standard sections and flanged joints are fully tabulated and are found to be sinall, e.g. average value of the complete field variation due to flanged joints is -0-055 + 0.006 gauss and for a standard section +0.122 + 0.032 gauss; th~; corresponding measurements for the fieYd gradient are +0.0002 + 0.0010 and 0.0311 + 0.0055 gauss/cm. The method of inspection for checking the magnetic properties of the chamber sections and their correction by annealing is described. There are 6 figures and I table.
