The numerical~inveetigation is ,extended to the modes Hll, Ell, H 12 , E129 H13 all-having the same azimuthal variation. The gradual mathematical transition from one, mode into another can Alto be physically realized by varying the ..surface impedance in a prescribed manner. Mode transducers of *tbi6 type can transform a less losay Bparious mode into a losay.one and so followed by a 10BBY-section can Berve.ae filters in an all-Metal wave guide run. The authors believe that the H mode'could be,ef-~ 12 fectively filtered out by employing this technique. There are 6 figures.

Moreover the Cady--Pearson interferanster cannot be uaed in liquids because of strong attenuation. rho authors describe a simple interforometer -which can be used In liquids amd which Is free of these troubles. The circuit of the interforanotor generator Is shown in Fig 1. quartz ql is the radiator while quartz(;2 is the stabilizing element. Negative iiedback is obtainW via the inter- electroda capacitance of the triodo used (see Fig 1). The equivalent circuit ofthe grid part of the generator is shown in Fig 2-.

A ring-type starter method, with preliminary retardation of the signal passing through the sample, is used in the apparatus. The mode of operation is pulsed. The apparatus operates as follows: A pulse generator feeds 'an acou- stical transducer, which radiates short ultrasonic pulses, into a delay line, at whose opposite end is a sound re*ceiver. The signal from the sound receiver is used for the next starting of the pulse -,venerator. Thus the pulse repetition frequency is determined by the S/194/62/000/004/00'1/105 D295/D308 Isayey, A.'A. and Khimunin, A. S.

TITLE: A new ultrasonic interferometer circuit PERiobicAL: Referativnyy zhurnal, Avtomatilta i radioelektronika, no. 4, 1962, abstract 4-5-34m (V sb. Prom.-primeneniye ul'trazvuka. Kuybyshevsk. aviats. in-t. Kuybyshev, 1961,167-173) TEXT: The circuit of an ultrasonic interferometer is described, which makes it possible to measure sound velocity to a su.-Cfi-ciently high degree of accuracy (0.01 - 0.02%) and to avgid the use of buf- rces in 'he.ele&'ro- fer stages and high-stability d,c. voltacre sou' U nic generator. As a result, the circuit of (the generator is co nsi- derably simplified and the number of valves reduced. The generator is assembled on one half of the 6,11-i6n (6N15P) twin t1riode with ca- ~pacitive feedback and with an oscillatory circuit in ihe -rid'cir- CA cuit. The oscillatory circuit consists of a slGabilized piezoelec- _-tric crystal and a quartz radiator connected in parallel ko it. The Card 1/2 ------ ---- S/1 94/62/000/004/059/105 A new ultrasonic ... D295/D308 radiator diameter is 20 and the radiation passes*into the liquid through a.wavelength thickness brass plate. At a frequency of 6 1.00015 MIS instability of the circuit amounted to 5 X-10-1 -for all distances between radiator and reflector. Standing-~,iave maxima are recorded on the basis,of the variation of the voltage across the- radiator, which is eqdal to 15 - 20.V when the.distance between ra-:- diator and reflector is 10 am, and which increases i4ith distance. For recording the maxima, the second half of t-he triode is used, i-_. the anode circuit of which is.connected a 15 mii-milliammeter '07 gether with a relay enablirig the number of Peak6s to be counted by means of a [%-S~ (MES-54) -pulse counter. The circuit is fed from. an ordinary rectifier with an L-filter,,after which a stabilovolt is connected. 2 figures../-Abstracter's note: Complete translation.7 ,Card 2/2 -------------- ISAUT, A.A.; KHDIUNIN, A.$.

A special dynamometer (Fig. 1a) had been designed by A.F. Zabrodin for torque measurements, provided with ribs between the openings in the cAsIng (Fig. 1b). The ribs are placed at an angle to the casing axis to increase r1g1& ity. Twist deformation causes compression of carbon transducers (5) by brackets (1) and (2) thus changing the current intensity In the resistance circuit. The end mill in holder (3) Is attached by bolts (4). Current is taken off the ro+At- Ing casing by carbon brushes and copper rings. The transducers (5) am aonnebt- ed in parallel so as to make possible a compensation of currents forming in-them from bending deformation. The affect of forces Px, Pz and Py.(Fig. 2) on ihe torque readings has been studied, and it has been stated that only the effect of forces In points (2) and (4) (Fig. 3) disturbed the resistor bridge ballance, but .the effect was slight and easily calculated because of its periodic nature.

Apart from end mills, the dyna, - eter perml-ts the milling with a single cutter. The component cutting forceswme dete'rmined by aATV-8000 (DTU-8000) lathe dynamometer of TsNIITMASh design (Fig. 2) [Abstvaotor's note: No design details are given.] The dynamometer was u.sed on a horizontal milling machine w1th vertical table feed; dynamometer readings were recorded with aMYTO-2 (MPO-2) oscillograph. The following conclusions viere made: 1) Forces acting on the back edge of mill tooth must be considered Inca- oulations of forces and power In milling. 2) The permissible wear chamfer ontte baok edge must be considered In calculations- 3) Metal sticking to the cutting edge has no material effect on cutting forces in milling "45" steel. 4) There Is no Increase of force at the moment when a tooth of the mill strikes metal. 5) Cutting -speed in 'the range 5 - 100 %/~min is practically of no effect on the cutl~-- Ing forces. 6) Specific work in mi"ling with end mills can vary in a wide range (from 300 to 900 m2) depending on the cutting conditions. 7) Workpiece metal " hardness in the range HB 180-300 leads to increased cutting forces, mainly ona.~- count of increasing forces acting on the rear tooth edge. 8) Tangential farceii on rear edge may be determined by extrapolating the dependence of the torqueval:- ue from the cutting depth. 9) When the milled metal Is carbon steel, stagging and sticking on the front, tooth edge has no material effect on the contact of Card 2/5 The Dynamics of the Cutting Process With End Mills A16i/Ao26 the rear edge with the metal being milled.

The operating conditions of 800 to 850% are close to actual operating conditions in industrial and.transport gas turbines. The turbine rotor is overhung and the disc has 32 slots in which were installed 16 test and 16 ballast blades-of which 8 served to measure the metal temperature by means of thermocouples. The shape and size of the blades, mado of heat resisting alloy 314-765 (EI-765) are shown in Fig.l. The gas used in the turbine was a mixture of the combustion products of diesel fuel grade AT (DT) and air, the gas temperature at the nozzles was 800*C. The blades were tested with a temperature in the dangerous section of 7500C, the rated speed of the rotor Card 1/5 S/114/60/000/012/002/609 E194/E484 Tests on Gas Turbine Blades.With Various Classes of Surface Finish WAS 7000 rpm, The-gan.flowed over the working surfaces of the blades at a speed of 25P to 300 m/sec. In order to avoid bending strosass, special precautions were taken to install the blades radially. Five groups of blades were tested with different classes. .of surface finish according to standard r"'CCT 2789-51 (GOST 2789-51), the first group was turned to a surface finish of class 6, the: second wawmilled to a surface finish,of class 6, the third was ground to a surface finish of,class 6, the fourth was ground to a urfaco finish of class 8, the fifth group was polished to a : urface finish of class 9, Three bladies of,each group were used plus an extra blade of group 1. The.blade temperature-and stress conditions were checked automatically and during the tests the deviation of blade temperature did not-exceed � 50C, the speed was maintained constant at 7000 rpm + 50 rpm. Of the 16 bladestested 12 were run to fa'ilure, that is until cracks occurred, Table 2 gives results of strength tests on.the blades from which it will be seen that blade No.7 with class 8 ground finish failed first and blade No.27 with polished class 9 finish Card 2/5 S/114/60/000/012/002/009 E194/E484 Tests-on Gas Turbine Blades With Various Classes of Surface Finitsh failed second. It is concluded that the strength of blades with. class 6 finish is not less than that of blades with higher clasfi'of finish. Finishing the blades by turning, milling or grinding makes no difference to the strength under the conditions of the test. The cracked blades were submitted to metallographic examination to establish whether the cracks arise on grain boundaries or in the body of grains at places of shear formed-by mechanical working. Typical photographs of microstructure are, shown In Fig-3 and 4 and itis concluded that in blades operating in a gas turbine at 760"C, cracks leading to failure originate only on the grain boundaries and that cracks develop within the body of the blade.only alon 'g grain boundaries. Shear that may occur in the surface layers during machining did not lead to cra0k f ormatlon. Previous work by other authors has shown that In 19 orvice,turb:Lne blades lose their high initial surface finish.. In7a previous article by the same authors, published In Enorgonashinostroyeniye, 1969, No.5, it was shown that in testa~ with gas and ash particles after 40 hours the blade surface Card V 5 S/114/60/000/0i2/002/009 E194/E484 Tests on Gas Turbine.Blades With Various Classes of Surface Finish becomes of class 6 finish and with clean gas after 140 hours... However, hitherto no spectal-observations have been made of changes in outface finish of actual blades installed in gas: turbines. Accordingly, the changes in surface finish were observed in the present tests and the results are given in Table 3. It is found that blades which are initially finished to olass 6 maintain their initial finish for 300 hours after which there la'a small deterioration in surface finish. In blades ground to class 8 finish the deterioration in surface finish commences from the first few hours of operation and is most intensive after 100 houx's, operation. In polished blades with class 9 fini *sh in the first few hours of operation there is intensive deterioratlon of the! surface finish. Thus the results obtained in the previous work are fully confirmed. It is concluded -that the rate of deterioration of surface finish is greater the higher the initial urfaco finish.

D040/Dll3 Various thread-cutting systems were compared because of'the lack of publi.sh- ed data on their effectiveness. Experiments were conducted using speciail split spe,3imens of Cr-Mo, Ni, and austenitic. steel, and out surfaces we-re measured using the "copy method" and a Linnik's double microscope. None of the tested cutting methods resulted in removing the allowance from both side5 of the thread groove; the highest profile accuracy and best surface finish were obtained with the cutting system based on the use of a thread-cutting head. The forces acting on a tap in the cutting process are analyzed -to il- lustrate.how much the real cutting process differs from the theoretical, and it is demonstrated that the undercutting of thread can be eliminated and the cutting accuracy raised if taps are provided with a guiding front portion so that every subsequent ta-D in a set fits the trace left by the preceding tap (Fig-14). The new taps based on this principle are described and illustrat-~- ed. These taps, calledM 72 (M72), should be solid for threading bores of up to 100 mm diameter, and with removable cutting tips for diameters above 100 mm. The material of -the cutting portion of the taps' wasPlB,(RlB) high- speed steel, The recommendations include the cutting and relief angles for threading dies used in thread-cutting heads for cutting different steel Card 2/7 S/590/61/162/000/001/005 Investigation of the process ...

Cutting by taps. - (1) Errors resulting from: faults in 'the cutting system of a set of taps, and errors produced by forces. arising in the cutting process mainly affect thread cutting accuracy. (2) The use of safety tap holders with a compensating element for axial forces considerably reduces the undercutting of the thread. (3) The system- Card 5/7 S/590J61/102/000/001/005 Investigation of the process D040/DI13 atic defect of undercutting may be fully eliminated by using the new tap design wi-,h a guiding cutting portion. (4) The cutting,speed together rith the cutting fluid affects the variations in the mean diameter. The combined effect of systematical and random factors results in mean diameter variations from 20 to 80/4..(5) Variations in the guiding portion taper anffle T fro- to 18030'and of the rake angle t fron, 5' to 206 within the cutting speed range of V = 1.2 -' 10 m/min do not materially affect the variation .s in the mean thread diameter. i.e. the variations are witbin 20-40,", which is with- in the tolerance field for class 2 accuracy. (6) Within the investigated cutting speed range, a variation in the rake angle of Y = 50 - 200 does not materially affect the smoothness of the machined surface, i.e. the average height of unevenness is 1.5 to 2/-. (7) Reduction in the taper angle f from 18030' to 80 helps reduce micro-unevennesges by 2.0 - 3-0~u- (8) Gen- erally in tapping using the self-tightening method, the smoothness of the upper and bottom flank on the thread differs. This difference is caused by forces arising in the cutting process, and it corresponds to the difference between two classes of finish.
