ABSTRACT; Since 1946, drngline excavators of tne=k-4/40 (boom len.-th 40 m, bucket capacity 4 cu.m) which are used' in open nit coal and ore mining have been produced.by the Soviet ,industry. Up to 1955, induction motors with phase rotors were used as a drive. However, a smooth.starting or braking, and the flexibility required for-changing load, could not be achieved with-them. Thereforep p roduction of an'excavator of the same type but-with a generator*motor drivel the generator being nrovided with three.windings was taken, up by the NDvokranatorskiy mashinostroitelInyy zavod (Novokrama- torskiy factory for machine construction).

Since 1957, these excavators.have been manu- factured with a- new type of drive using induction motors. At the above-mentioned factory five,of thase excavators were produced in 1957, and in the same year one of these, viz., the excavatoj7 Nr 153, was tested under the direction of !T.Ye.Kuvayev, university teacher~:at the department for U -below, mining electrical engineering of the association given, in the Razdolskiy sernyy kombinat (Razdol sulphur trust). The main results of these tests are:given 1-lere. As they show, tile technical and operating data have been.substantially improved by the new technical solutions found. New feaLures were: Use of saturated reactors in the stator circuit o--," ~be reversible motor, inductive reactances in the rotor circuit, of the main winch drive motor, and singlephase braking of that motor.

Since 1955 a generator-motor syster embodying a three-winding generator has been used'to drive these mechanisms. The kinematics of the excavator.mechanisms and the operating characteristics of the machines remainod unaltered. The main data of the two types of drive are compared in a table. The new drive is much more compli- cated and expensive than the old and investigations have been made to see whether its use is jus.tified. The drive of the main winch should not be damaged if the motor is stalled when the bucket enters theiround. The circuit and characteristic curves for induction'motor drive of a Winch are shoim in Fig 1.

Oscillograms of raisin- and unloading the scoop appear in Fig Oscillo-, grams of the normal process of digging7 in which the scoop is not stalled, followed by lifting and unloading).are~seen in Fig These oscillograms are analysed to show that- there are considerable dynamic load variations on the shaft of the motor driving the main winch.~':,+Short-term oscilla- tions arise from the application of friction brakesl and longer oscillations are associated with the motor and' reduction gear. It is considered that the.application of C3 the friction brakes at high motor speeds is the main cause of the unreliability of excavator type ESh-4/40. The need., to apply the bralkes at high motor speeds is due to the - kinematics of the main winch system which in effect combines Card 2/4 two.oporating mechanisms.

The best solution would be to provide individual drives for the traction and liftinc- mechanisms. The second class of oscilla.tions consist of a fundamental frequency with harmcnI.cs:and is physically explained by reference to Fig 6. The funda- mental-is the frequency of rotation.of the shaft of the main motor and probably results from inaccurate alignment and centring of the motor and gaear.phafts The high- 2 frequency oscillations originate in~klhe g;aring. .

The-8-5 Bev protons were obtained from the proton synchrotron of the OIYaI. The proton beamLwas incident~on the, emulsion surface perpendicularly. The emulsion contained (2.90 � 0.06)b,022 hydrogen atoms per cm3. An immersion objective of magnifying power 630~ was used for evaluation. In the central part of the layer (2 - 2 cm2), the flux density was (1-9710-05).105 particles/cm2. 3,.35 cm3 of the emulsion were studied in all. For the (double) evaluation, those two- pronged stars were selected which indicated elastic pp"!Iscattering.

According to the range of the slow proton, they were divided into throe groups : 1) 10)A~~:R/,100~A; 2) 100 ,AA A= R < 20 v 000~4; - and 3) R,,>-20,000/A , The tracks of the first two groups were~practically black on account of the high sensitivity of the emulsion. The efficiency of twofold evaluation for the different groups was (85t))~~, ~(~2.5tO-8)%, and (78i5)%. 145 events of elastic proton scattering on free hydrogen~. were selected according to criteria discussed here. The'results of -the. analyses of these stars are shown in Figs. 1-3. Fig. 1 shows:the number N of observed events as a function of jAyl. Aq is the difference betweenAhe measured emission angle of the recoil proton and the angle that would correspond -to its path accordingto the kinematics of elasti,clsc&ttering. Fig. 2 shows 17 as a function of %/ where t is the non-coplanarity angle, and A?- the error in its measurement. Fig. 3 shows N as a function of 14 Y1 . Here, N denotes those cases which were selected according to the first two criteria (R -T relation and coplanarity);-Avlis the difference between the angle of the scattered proton and the angle:of the path of the recoil proton according to the kinematics of elastic scattering.

The theoretical function dd'/d-ft- f(q) obtained accoIrdin5cto the model of a purely absorbing disk (radius of the disk: 0.94-10-1 m), does not represent the experimental results. Nor can this be achieved with other models of purely absorbing protons. The model of a homo geneou's, semi-permeable sphere (Curves 2 and 3) is best suited for the description of the experimental results if the refractive index is assumed to be different from unity. The model parameters that appear to bemost suitable are given. The authors thank D. I. Blokhintsev, V. I.Neksler, M. Danysh, M. I. Podgoretskiy I. Ya. Pomeranchuk Ya. A.

(2) The departure of experimental fron calculated results is three times the overall error. This is due to neglect of the dep~!ndence of scattering amplitude on proton spin states, and to neglect of i to real part, both of which wore confirmed by experiment. ~ However, the real part does not exceed half of the imaginary part.
