SOV/115-59-3-12/29~ AUTHOR: Samoylov, VJT. TITLE: The Errors in Balancing Pistons of!, Pistoi-; Gages (Pogreshnosti uravnoveshivaniya -porshney gruzoporshnevykh manometrov) PERIODICAL: IzmeritelInaya tekhnika, 1959, Nr 3, pp 19-21 (USSR) ABSTRACT: The exactness of pressure measurements with spring- loaded piston gages depends mainly.on the de- gree of accuracy zo wnich'the effective piston areas are known. These effective areas are.usually determined by hydrostatic balancing of.the pistons of two gages connected to one press. The ac- curacy of measuring the effective area depends on the sensitivity of the entire system consisting of -two gages one press and the gage tubes. For the given case, the sensitivity,of 'the individual gage is not of basic importance. Consequently, for evaluating the maximum accuracy which may be achieved bv Dressure measurements with spring-loaded Card 1/3 - -9. piston gages is necessary to consider the SOV/115-59-3-12/"29 The Errors in Balancing Pistons of Piston Gages sensitivity of the aforementioned system. Investi- g,ations of gage -.3iston movements produce para-, meters characterizing the sensitivity and permit- to evaluate the errors of the hydrostatic balancing. The sensitivity value of a system permits an evalua- -.,ion of the.accuracy which niayrbe achieved for measur- ing the effective piston areas. It may be used for.. comparing diffbrent.systems with each other and for detecting leaks in the press. The author determines -;he conception piston-liquid-piston, stating that -~he equation M1 m2 is actually correct only for FT ~ F2 the balanced state of a system. Forcalculating, the magnitude C, the sensitivity of the system in this case, a differential equation of the movement of the Card 2/3 pistons and the liquid in the gage -tubes is SOV/115-59-3-12/29 The Errors in Balancing.Pistons of 7?isto, gages kriven. At high pressures, the deformation effect on the pistonipairs.should be taken into considera- tion and the change of the liquid viscosity. Based on the differential equation formulae are developed for determining the measurement errors which might occur dup to inaccurate balancing. As a conclusion two gage.. systems are cited.- If the speed of the VisGon motion2is expressed in mm/min and -the pressure in kg/cM 32 then the MOP-60 will have a Senpitivity of 10 -10.4 units, whereby an error of 10--L kg/cm-- is permitted for pressure measurements* For the 1-25.00 gages the sensitivity is 10 units at pressui~i:-d,oi u co 2000 kg/cm2, whereby the error is 10-1 kg/cm These errors must not be neglected when performing reference measurements and in some cases when testing instruments of the first category.

TITLE: The use of epoxide compound as vacuum-tight material PERIODICAL: Pribory-i tekhnika eksperimenta~lno- 5, 1961, pp. 16o - 161 TEXT: Com-oounds based on epoxide resins 25*A-6 (ED-6) and 3A--7 (ED-7) were used as vacuum-tIght materials in the development of a single electrode focusing lens for an ion source. The evolution of gas from cured specimens was.first~ assessed by tests in a vacuum chamber with an initial vacuum of 5 x 10-7 Mm F.'[g. Without sIpecimens the rate of leakage over 24 hours was 0-03 cc/hour. Two spec:Lmens,of 1 kg were then placed in the chamber-, they were made of cured compound based on rosins 3-3-1,(E--37) and )A.6 (ED-6), polymerised at a tempera- ture orf 150 C for twenty-four hours. The compound based on resin. E-37 was loaded with dust of high-voltage porcelain, ground -to give 10% residue on a number 100 sieve. The filler in the compound based on resin ED-6.was quartz sand, ground to-give a Card 1/3 296:5 S/i2o/Wooo/oWo27/034 The use of epoxide compound .... E194/E355 residue of 10.5%,. The proportions used were epoxide resin 100 parts by 4eight, filler 250 Parts by weigh 't, phthaleic. anhydride 30 Parts by weight. The presence of these samples did not alter the rate of leakage into the chamber in tests carried out at a temperature of 18 - 20 0 C. A single-electrode focusing len's was then constructed but the usual ceramic insulators were completely replaced by insulators of epoxide compound hoi-rever, the filler was reduced to 165 parts by weight. particular care was taken to avoid excessive heating of the mJxture in the early stages of curing, which might. have caused cracking. During.the course of a year's operation the lens was periodically heated to a temperature of 8o 85 0C and during this time the vacuum dropped to 1 x -6 10 mm. Hg~; this was probably due to the presence of a rubber packing between the quartz tube and electrode of the lens. During this service life there were neither cracks nor leakages.

Mechw_* nical and electrical properties of the hardened epbxy compound are investigated and described as functions of filler grain size, filler proportion etc. Tests showed that, at equal filler purities, filleis of quartz sand and aluminum oxide deliver an electri;_- cal strength which is practically independent of particle size, filler proportion or filler material. However, bending strength noticeably increases with a decrease of particle size and the ratio of epoxy to filler. The process of accelerator tube con- struction is described. In a two-year test operation, with a tube length of .5 meter operated in air, the operating voltage across the tube was maintained between 150 and 160 kilovolts. At an outside temperature of 200C., a vacuum of (4 - 5).10-7 torr was attained. No leaks were observed during the two years of operation.

In order to establish the effectiveness of such heat treatment 9 the authors carried out experiments with specimens and drills made of the steels R9 alid E18 which, prior to treatment with steam,.were hardened, tempered, sharpened and ground. Thetreatment with steam was effected in a hermetically closed electric furnace, a sketch of which is shown in Fig.2,''j-n which the temperature was maintained automatically within + 50C. The steam pressure, was maintained at 0.1-0.2 atm. T-o prevent the formation of Fe 0 on the machined s faces Card 1/4 the steam has.to be introduged in the super-heatuerd state'.

Atmosphere Only then will a f-ilm form consisting,of magnetic iron oxides which is the reason for the high corrosion stability-~, and the good appearance of the thus treated tools., The treatment procedure is graphed in Fig.l. Prior.to introducing steam, the temperature is raised to 350-370'c and the tools are held at that temperature for 20 to 30mins. Then,steam is introduced and the temperature is maintained at the same level for a further 30 mps. Following that, the temperature is raised to 540-550 C,,maintained constant at that temperature for 30-60 m,ins and, finally, cooled in air and quenched in oil. The graph, Fig.3, shows the measured thickness.o~f the oxide film on the steel R9 treated in a steam atmosphere at various temperatures with a holding time of 30 mins; in Fig.4 the thickness is graphed of the oxide film on the steel R9 treated in a steam atmosphere at'5500C as a function of the holding time. It was found.that the oxide film produced by steaming is considerably denser than that produced by Card 2/4 alkali oxidation. The corrosion stabilityland the SOV/129-58-11-7/13 Heat Treatment of Tools tAade of High Speed Steel in a Steam Atmosphere resistance to seizure was also measured as well as the service life. On the basis of the obtained results a heat treatment regime in a steam atmosphere was developed for tools made of high speed steels. The steam treatment is recommended as an additional treatment of sharpened-and ground tools.for the purpose of improving their resistance to corrosion and their cutting performance. Steam is also recommended as an atmosphere in the furnace during tempering for the pur,ose of preventing erosion of the tool surface;,j-n P this case no inter-cycle chemical tFeatment is necessary. After steam treatment at 500 to 600 C a dense film~of the magnetic oxide FeAOLL formst the #Lickness of which is 1-4~L. The presened n the surface of such a film leads to an,increase of the adhesion temperature (build UP of machined metal onto the high speed steel) by 100-150 C and this explains the improved cutting. properties; furthermore, steam treatment does not bring about a drop in-thesurface quality during heating in Card 3/4 saltpetre and in air, which is also important from the SOV129-58-11-7/13 Reat Treatment of Tools Made of High Speed Steel in a Steam Atmosphere point of view of improving the service life of the tool.

Differential apations of the shell based on the momentless theory are used, with no consideration of tangential forces, and a finite system of differential equations Is derived for the oscillations of a shell with a liquid. 71te hydrodynamic pressure is found by means of a Lagrange- Cauchy Integral, In which the determination of the velocity potential requires solution of the'Neumann problem for a semi- spherical shell. The problem of the velocity potential for a somi-spherical cavity with rigid walls has been solved elsewhere in the literature. In the present article, a similar problem, but with different boundary conditions, is considered. The solution given Is for an ideal liquid, the free surface of, which remains Cardl/4 ACCESSION NR: AP4043423 -planar (that Is, the development of waims on the surface Is not conaMereM.

A spherical shell is assumed to be composed of two hemispheres. The hemispheres are fixed in a diametric- plane away from centrifugal forces and unrestricted with respect to normal motion. is assumed that each hemisphere can move stepwise in any direction along the normal.

A liquid filled sphere was fastened- to a vibration stand by means of a so cket. Eight transducers or ere attached to the shell to determine vibration amplitude.

PP 53--57 (USSR) ABSTRACT: A s rig was set up to study the solubility of pecial test calcium compounds in steam and their behaviour during steam raising in conditions of once-through boilers. The test rig is illustrated diagrammatically in Fig 1 and described; the most important part of it is a steam- raising tube of 10/15 mm diame-IL-Oer (6/10 mm n t5he superheat zone) that imitates the operation of a coil in a once-through boiler. Feed water is pumped into one end of the tube and the steam coming-out of the other.is condensed. The heating arrangements. the measuring instruments and the test procedure aie described. After operation the rig was cleaned out, one zone at a time, Card 1/5 using pure distillate or in som-ecases acid. The tests ~,OV/96-59-2-9/18 The Behaviour of Calcium Hydroxide and Calcium Chloride in the Circuit of a Once-Through Boiler weremade at steam pressures ranging from 150 to 300 atm, temperatures up to 6500C and other conditions as given in Table 1. Curves of the calcium ion content in. the steam as function of the temperature when the rig is fed with a solution of calcium hydroxide are given in Fig 2., from which it will be seen that over the range of 480 to 59000 the calcium content is practically constant. There is a considerable fall in the calcium content at a temperature of 4700C particularly at a pressure of 150 atm. It is suggested thatthis is because, at temperatures below 4?OOC, the calcium'is mainly in the form of-calcium hydroxide and above this temperature mainly in the form of calcium oxide. As calcium oxide seems to be less soluble in steam than calcium hydroxide, it will crystallise out at temperatures above 4?OPC if the concentration is greater than the.solubility in steam at this temperature and pressure. The causes of the occurrence of calcium hydroxide in boiler water are then considered.

A curve of 'the calcium ion content in the steam as a function of temperature when the rig is fed with a solution of calcium chloride at a pressure of --ed that at the 150 atm is given in Fig 3. It is suggest lower temperatures the calcium chloride is decomposed to form calcium hydroxide.and at the hig1her temperatures above 4700C calcium,oxide is formed. In order to evaluate the accurac-y of the results table 2 gives values of possible errors in determination of the concentration of calcium ions in samples of condensate. Inthe tests when the rig was fed with calcium chloride solution the-steam condensate was always acidic which points to the presence of free hydrochloric acid, whilst the deposits were alkaline and so contained some form of calcium oxide. At high temperature, calcium chloride is slightly hydrolised even in aqueous solutions but the process is much more intense Vaen boiling occurs and the volatile hydrochloric acid is removed with the steam. Card 3/5 The ratio between cona exit rat J_ ons of calcium and chloride SOV,/96--59-2-9/18 The Behaviour of Calcium Hydroxide and Calcium Chloride in the Circuit of a Once-Through Boiler ions in the deposits in the tube was variable and depended on the concentration of calcium.chloride, in the feed water. Graphs of the contents of calcium and chloride ions in the steam as a function of temperature are given in Fig.4 and 5 respectively. Within.the limits of experimental error the carry over of calcium ions in the superheated steam does not depend on the concentration of calcium chloride in the feed water but the concentration of chlorine ions in the steam does depend on this concentration and this confirms the author's ideas about hydrolysis. Previously published data about the solubility of calcium chloride obtained by the radio-actilre isotope method in an autoclave are given in Fig 4. Comparison of these results with those obtained in the rig of the Moscow Power Institute shows that carry-over of calcium ions is governed by the solubility of calcium chloride and possibly also by the solubility of the hydrolysis products of calGiUm chloride at temperatures up to 4700C.
