Properties of initial colonies of the ;I livirulent strains were compared with those of the phagoresistant mu- Jtants isolated from the virulent strains. Results show that the ifrequency of phagoresistant; mutant formation in virulent strains is I 4ower than in avirulent strains. The frequency does not appear ~:dependent on the phage under examination, but somewhat dependent on ithe degree of virulence of the investigated strains. Phagoresistant. mutant properties are characterized by instability. Sensitivity of .:initial colonies to phage action resulting in resistant variants and the formation of phagoresistant mutants in the presence of phages suggests that phagoresistant.rautant formation is adaptive in origin ..and contradicts the spontaneous mutation selection hypothesis* Orig, art, has: 4 figures and 1 table,.

A batch of specimens was divided into two equal 6ups by random selection. The first group was tested for momentary tensile strength. The data were arranged in increasing order from a to , and each specimen was assigned min Umax its own ordinal number., It was assumed that if the second group of specimens were tested in the same manner for momentary strength, the distribution of data would be the same as for the f rat group. The second group was tested for permanent sta-1 tic tensile strength with the same stress being,applied to all specimens. The in- dex of relative loa capacity a /d for each~specimdn has its own value asso- p m Car 112 L 3571,-66 1ACCESSION NRs APS024918 Ic'iated with the variance in the Individual values of the momentary tes'ts. I. e., in' spite of a common stress for all samples In the second group, the specimens are test- ed at various levels of relative load capacity a. In addition to this, the static urability of the spcimen in the second group of tests increases with the indivi- dual momentary strength of the specimen. The values of static durability for the specimensinathe second group were thA-n arranged in incivasing order and each speci-~ 'men was assigned its own number. The specimens in the second group were then assign- ~ed a momentapy st'refigth corresppnding"to the ordinal numbers of the specimens in th ifirst group.~ ThusTor each ordinal nVmber there is a m6mentary strength a and a static life T (in hours), the static stress being identical for all specimmens. These data are used for plotting a permanent strength curve with the relative load -axis. The results show a considerable reduction in variance ~factor a along the y 'of data when compared with momentary strength tests alone. Orig. art. has: 3 'figures, I table.

PERIODICALt Voyenno-meditainakiy zhurnal, 1958, Nr 2, pp 76-77 (USSR) ABSTRACTs The article deals briefly with problems connected with the treat- ment of the lightly-wounded during re-grouping operations, when .medical units must be re-locatedt often over considerable dis- tances. The author briefly.discusses the case of the 3rd shock &rimy during re-grouping operations on the Baltic front in Janu- ary, 1945, involving a 500 km march and the transportation of 1058 lightly-wounded troops. fie compares the periods required for treatment of lightly-wounded patients during the re-grouping (Jan- uary), defensive operations (February), and offensive action (11ar- ch), both from the day the wound was received, and from the date of receptAn of.the patients In the hospitals for the lightly- Card 1/2 wounded (GLR). These periods were 72 and 64 days (Jan.), 25 and SOV/177-58-2-14/21 on the Organization of Treatment for the Lightly-Wounded During Re-grouping of the Army 10 days (Feb.)t and 29 and 23 days (Mar.) respectively. Moreover. he adds, that'the character of the wounds treated during all three periods was similar. The main reason for such long periods of treatment during re-grouping, states the author, wan that treat- ment was possible only during brief halts on the road, and that without benefit of fully not-up hospital units, as the army was under way most of the time. The author also deals with other as- pects of normal treatment that suffered as a result of the re- grouping operations on the period required for the treatment of lightly-wounded patients, that these be concentrated in one army GLR In the rear, to join their units after recuperation.

The present Iauthors show that it is possible similarly to inject charged particles from behind the mirror, provided the strength of the magnetic field at the injection point is kept proportional to that of the mirror field during establishment of the latter. To teat the method, 100 keV electrons were injected Into a 40 cm diameter 150 cm long magnetic mirror system with a mirror ratio of 2.5. The injector consisted of a ring-shaped electron gun mounted on the axis of the system, which produced a conical boam of electrons making an0angle of 209 with the piano normal to the aLxis, i.e., having a vertex angle of 140 The magnotie,field at the electron gun was kept proportional Card 2/2 UDC: 533.9 7 &420-6 NR: AP60312ft to the mirror field during the rise of the latter with the old of a special pulsed solenoid mountOd within the chamber. With a beam spread of 10 0, Dome I" of the injected electrons wore trnppod botwoon the mirrors. The lifetime of the trapped electront within the trap was from 0.01 to 0.1 see and was limited only by scattering; on the residual gas. There was observed an increase in the fraction of the iiijected electrons that were trappod with incronsing injection current. This incre 'Oso is In accord with the theory and is due to space charge effects. At very high injection currents, however, the oscillations reported by R,,I,,Budker,, S.S.hioiseyov, and the present authors (Plasma Physics and Controlled Nuclear Fusion Research (Conference proceedings, Culham, 6-10 Sept., 1965), 11, 245, 1AEA, Vienna, 1965) limit the density of the trapped particles.

TITLEt Investigation of lead in a continuous merchant mill PERIODICALt Izvestiya vyeshikh uohebnykh zavedeniy. Chernaya metallurgiya, no. 9, 1960, 110-115 TEXT: Theoretical lead caloulation methods exist for rolling strip on smooth rollers only. The new method desoribed permits measurements of lead on any rolling mill. It is based on measurement and comparison of distances passed by a point on the surface of the roller and a point on the surface of metal being rolled. Two electromechanical pickups (interrupters) watch the velocity of the rollers and of the strip. The pickups (rig.1) have a collector (1) at the same axle (2) with a disc (3) with file-cut on the edge to prevent slip. ThW axle runs on 'two ball bearings in casing (5) and Is fixed by the bushing (6) and cover (7), and sealed with gaskets (8 - and 9) and packing (10). The collector plates are connected to the pickup mass through the contact (11) so that the brush slides alternately over the conducting and over the idle plate when the disc rotatesq and the circuit Card 1/0 S/148/60/000/009/015/025 Investigation of lead ... A161/AO30 interrupts. The brush holder (12) is attached by means of the bracket (13)- The circuit closes as many times during one revolution of the disc, as many collector plates are connected with the pickup body. Two like pickups rotating at the same velocity give the same number of pulses in a time unit, and the velocitv of the two discs in contact with the roller and with the strip will differ by the value of lead. A photo shows the pickups in operation (Fig.2). Pulses from the pickups can be recorded on film with a MflO-.2 (MPO-2) oscillograph, or they can be counted directly with the use of a special system. The oscillographing is simple. An oscillogram is shown (Fig.3). But the processing of measurement results is not convenient. The special counting system is an electric computer, illustrated in a block diagram (Fig.4). Voltage pu-lses from the two pickupsMA-1 andMA-2 go into a limiting circuit 080 -1 or 081f -2 (Ilogranichitell vkhodnykh impull sov" - input pulse limiter), for even a slight beat of the collector changes the transition resistance between it and the bruoho and the pulse amplitude changes. Pulses limited in amplitude go on to amplifiers Y -1 and Y -2, and on to the shaping circuit 00C consisting of a half-cycle multivibrator with cathode and anode-grid connection. Sharp output pulses from thecP14C with Card 2/V S/148/60/000/009/015/025 Investigation of lead ... A16l/AO30 50-60 microsecond duration are the count pulses. A special control system has been built for a precise simultanecus start and end of the count from both pickups, with start push buttonflK earthing the anode voltage circuit through a high-resistance resistor. The voltage difference formed at the ,moment is differentiated and fed into the pulse-forming circuitcP1,1 , and the voltage front rises abruptly. The.pulse from thecbt4 is differentiated, amplified in the ampli.fierY-3 and fed to start the control triggerYT. The excitation time of the trigger is the metering time. The triggerYTcontrols through the cathode follower 911, the coincidenae circuitsH receiving also the pulses from theCPPI(-' units. The counting storage unitsCHP -1 andcHP-2 count pulses during ihe excitation time of the triggerYT. The yr is re- turned into the at-t position by again pressing.the starting push buttonqK. The counting storage units are binary counters, but the counters used in experiments,4ore decade zounters4 (with t1n pries-connected triggers)permit- ting count + Of 271 2 1 25+ 2 + 23+ 2 + + 20 - 1023 pulses. This was sufficient at a rolling speed of up to 10 M/aeo and 2 sea metering tirae. Neon lamps are connected into the anode circuits of the triggers for fixing the excitation. The system is returned into a start position after metering Card 3/0 S/148/60/000/009/013025 Investigation of lead ... A161/AO30 by the synchronization push-button KC through the pulse shaper4M, differen- tiating circuitA19, detectorA for producing unipolar positive pulses, and the amplifierY -.4. This return system works like the counting control Sys- tem. The portion of Pig.4 separated out by a dashed line shows the portion of the system that was absent In the described operating model, but which car, easily be bui,lt. It is a system for automatic comparison of data that can produce digital readings, or readings in the form of voltage or current on a dial indicator graduated in lead units, or on an oscillograph. This automatic comparator may be in the form of a usual parallel adder working as subtracter. In this case it would be controlled from a shock oscillator excited by synchronization pulse with subsequent formation of the produced pulse series into a series of sharp pulses for controlling the operation of the adder. This effect can be obtained also with the use of any type of delay line. This comparing unit can solve the equation 100 An% n f3 where i is the lead value in per cent;LNn - the difference of the counted Card 4/10 s/j4q/6o/ooo/ooq/o15/025 Investigation of lead ... A161/AO30 pulse values; nk - the number of pulses counted from the pickup on the roll. The metering error is 0.098% at maximum pulse number 1023. Experi- ments were carried out on the planishing stand No.9 of the mill, in rolling spring steel strip 76 x 9-5 mm. The results of pulse count are given in a table. The mean lead in normal rolling was 4.9%, the maximum 7.6%, and the minimum 2-7%. The effect of tension on the lead is shown in curves (Fig-5)- At a certain degree of velocity miBmatch, when the lead curve crosses the X exis, the strip slips in the rollers. The front tension increases leadp but it was produced by the No.10 stand alone in this oaael and the rear tension from the stands No.1 to 8 was stronger. Conclusions The suggested metering method permitst a) measuring and recording on osoillograph film the value and the variations of lead or lag in any rolling mill; b) to reveal slip of' rolis; o) to determine the rolling diameter in rolling in grooves from the relation nrl nB where nrl- the number of pulses of the pickup on the strip; ng - the pulses Card 5/ S/148/60/000/009/015/025 Inveatigation of lead A161/AO30 number from the pickup on the roll; DIr - the roll barrel diameter; DK - the rolling diameter, There are 5 figures and I table.

The meaL velocity of electrons rises aft.er the jump, while their charge is considerably reduced without any variation in zhe space charge of the ions. The author made experiments on electron beam within a cylindrical system. A diagram illusts-,,Js~s typical oacillograms simultaneously recorded by two probes. The potential in the beam center is determined by the space charge of secondary electrons as soon as the high-tension a--r- refit has been switched on; and it drops with '-ncreasing ion!c compensation. However, if the beam potential is almost equal to zero, compensation is slightly slowed down, followed up by a rapid upward potential jump and a somewhat slower drcp. The jumps then recur in a period inversely proportional .Q the pressure within the system. Some additional experiments were made for a more exact checking of the mechanism of the found oscillations: 1) A constant potential V col was applied to the collector, and the bear, potential was investigated by means of a net-ehaped probe. The shape of oscillations slightly Card 213 varies when negative potentials are applied to the collector, BOV/2o-128-3-17/56 On a Kind of Relaxation Oscillations in an Electron Beam whereas the amplitude of oscillations decreases considerably and does not depend on Vcol when positive oscillations occur at the collector Vcol > 30 v). 2) The found oscillations depend but little on the other parameters of the system. 3) Oscillations vanish when 'the amperage of primary electrons drops. In some cases, relaxation oscillations excite oscilla- tions of higher frequency, %hose mechanism has not yet been investigated in detail. There are 4 figureMand 9 references, 4 of which are Soviet.

The in- vastigation is carried out by the impulse-prooens by means of mea- suring the electric fie,_Id of -the beam-apace-charge. For this pur- pose a search electrode in form of a ring was located into the an- ode. The observations were made by theaid of an impulse-oscillogra]~L The behavior of the electron beam with respect to time was investi- gated according to the oacillograms of the electric field of the beam and of the current flowing towards the collector. At sufficien- tly small amperages the usual compensation of the space charge was observed in accordance with E.G.Linder and X.G.Hernquist (J Appl. Phys., 21, 1o88, 195o). Bat as soon as the amperage exceeded a certain 1critical value, the course of the oscillogram changed. The field voltage remained practically constant for some time after swi- tching on the high voltage, but afterwards it decreased intermitten.- tly. The current flowing towards the collector, however, increased all the time in order to reach its steady value in the moment of Card 1/2 of the jump. After the jumps the usual compensation.was observed On Compensation of Space Charge in Electrnn Beams. 57-11-24/33 in the beam. The fact that before the jump a part of the current does not reach the collector can only be explained by the presence of the virtual cathode in the beam, Which reflects some of the electrons. The voltage of the electric field immediately after the jump (E2 ) did not depend on the residual gas pressure and fell approximately in linearity with the increase of current. The time 12, in which the field-voltage jump took place, was measured. A qualitative explanation of the observed phenomena is given. There figures and 5 Slavic references.
