This refers mostly to the hand- ling of loose freight and goods in packets inside ship holds and railroad cars. The tsentralInyye proyektno-konstruktor- skiye byuro (The Central i)esign-Construction Departments) of the Ministerstvomorskogo flota (Merchant Marine ministry) are developing new machines and mechanisms for the complex me- chanization of loading operations at sea ports. The authors give a detailed description of the following loading mecha- nisms: 1) the PTS-1 coal loader, designed by Engineer N.T. Sergell, with a capacity of 350 tons per hour; 2) the FTS-2 for the loading of ships with a capacity of 100 tons per hour; 3) the PTS-4, designed by the TsPKB-4, for the loading Card 1/2 of 5W. manganese ore; 4) the PTB.-2, designed by the TsPKB-3, New -eransloadinC Equipment at Sea Forts 118--e-4-11/23 for the loading of iron ore, bauxites, etc. into ship holds, with a capacity of 150 tons per hour; 5) the TsPKB-3 designed a scraper grab crane with a lifting capacity of 10 tons; 6) the PSG-200, designed by the TsPKB-3, with a capacity of 200 tons per hour (the loader has been designed particularly for the loading of manganese ore); 7) the bulldozer BMT-1, designed by the TsPKB-4, for the scraping of loose freight in ship holds, has a capacity of about 30 tons per hour; 8) the TsPKB-3 has designed (Initiator Engineer D.B. Spektor) a fork lift with a lifting height of 4.5 meters, to be used in ship holds; 9) for use inside railroad cars, the TsPKB has designed a fork lift with a lifting height of 1.5 meters and a load capacit.v of 1.5 tons.

Mutual Interference of Combination Frequencies PERIODICAL: Zlektrosvy&z', 1959, Nr 7, pp 26 - 32 (USSR) ABSTRACT; When transmitters are in close proximity, voltages at the fundamental frequencies and harmonic frequencies of adjacent transmitters occur at the anodes of the outputstages. Experimentally obtained graphs of these voltages, measured on the anDdes of the output stages of u.s.w. transmitters, are shown in Figure I as a function of the spacing between the transmitters. To ensure high efficiency, the output stages operate under non-linear conditions. Due to this non-linearity, combination frequencies are formed and also combinations with the frequencies of adjacent transmitters. The amplitudes of the anode current combination-frequencies components are given by: I D_ Un- 11 U a KOM6 34L gm p n=2 n-1 Cardl/5 lilln'.1 sovio6-59-7-4/i6 Mutual Interference of Combination Frequencles which shows that the amplitudes of the components of the anode current are determined by: 1) the equivalent admittance of the valve - D3-19 2) the output stage grid voltage U 9m and the amplitude Up of one of the voltages produced at the anode of the same valve; 3) the non-linearity of the volt-ampare characteristic (a n and n ); T1 and Yj are any pair of natural numbers, the sum 1 1 of which equals n - 1 Analysis of the effect of these factors on the values of- the amplitudes of the combination frequencies enables the following conclusions to be made. A) Increase in the equivalent adm~ittance of the valve leads not only to increase in the amplitudes of the existing combination components but also to the appearance of new Card2/5 combination frequencies in the anode current. These components sov/io6-59-7-4/16 Mutual Interference of Combination Frequencies are negligible for small values of D,) B) The presence of very high voltage U gm is one of the root causes of the formation of combination frequencies. C) The number and strength of the combination frequencies increases with increase in the non-linearity of the valve characteristic. The antenna circuits are often tuned by DC switching apparatus, in the circuit of which is a semiconductor or vacuum diode. In some radio stations, the amplitude modulation in the transmitter is checked by using a diode connected into the antenna circuit. With close spacing of the radio stations, on these diodes there appear , as well as the fundamental operating frequencies a nd harmonies of the given transmitter also voltages at the frequencies and hazumnic frequencies of neighbouring transmitters. As a resTalt,-combination frequencies occur in the diode current. The amplitude of the current can be expressed in the form: Card3/5 sov/io6-59-7--4/i6 Mutual Interference of Combination Frequencies I Ae- _m tP k k P Uk and U are the amplitudss of voltages, the frequencies of which form a given combination: U, Is the amplitude of the transmitter freqaency voltage, U p is the amplitude of the voltage of the "picked-up" oscillation. The - indices n-m and m indicate the degree of non-linearity of the diode characteristic and the order of the picked-up frequency. The coefficient A takes the nature of the non-linear element into account. The author considers the radiation field of the combi-nation. fr--:-quencies. From 1-6-he experimental data of field :3trength versus spacing of the transmitters, presented in Figure 2, it is seen that when the combination frequency coincides with the reception frequency of a nearby receiver, communi- cation wIll be either totally suppressed or will be received Card4/5 with a large degree of interference. sov/lo6-59-7-4/16 Mutual Interference of Combination Frequencies After considering the effects of the various non-linear elements of the transmitter on the field strength, the authov cons�de3ra the follow�ng methods for- veduc�ng the combination interference: 1) reduction in the number of non-linear elements; 2) choice of the valve and working conditions of the output stage so that the amplitude of the combination frequencies is as small as possible; 3) reduction in the value of the voltages picked up. This can be achieved by increasing the selectivity of the output stages. There are 2 figures. SUBMITTED: December 20, 1958 Card.5/5 CMMCKBIT'KO, Tu.P., inzh.; NTING(79 L*A9, in~mh.

Odessk. pohiekhn. in-t, 1957 (1958), Vol 17, pp 223-254 ABSTRACT: Introduction -of Sb iAto gray cast iron (Cl.) markedly refines the structure and improves the antifrictional properties of the CI but lowers its mechanical properties and increases its hardness. High antifriction and anticorrosive properties combined with satisfactory mechanical characteristics may be ensured if the 5b concentration in the C1 is maintained between 0A and 0.75%. The new antimonous C1 exhibits good casting properties and, despite its increased hardness, is readily machinable. This type of C1 may be obtained by means of introducing Sb into the Cl's of the types SCh 15-32, SCh-18-36,et al. The antimonous antifrictional CI may be employed instead of bronzes and babbitts. Optimal results in saturating the surface layer.s of Card 1/1 iron-carbide alloys with Sb were obtained in a mixture of charcoal and Sb oxide. A.

TITLE: Usixi Antimony-Alloyed Cast Iron Instead of B ronze PERIODICAL: Stanki~i Instrument, 1960, No. 10, pp. 29-31 TEXT: As a result of research work and protracted investigations, a new antifrictioni'material has been developed - antimony-alloyed cast iron. The,metal-~ lie antimony is added directly into the ladle with the molten cast iron of grade S 15-32 (Sch 15-32) and '_"~ 18-36 (sch 18-36). Based on laboratory and service tests, the optimum composition of antimony alloyed cast iron is the foiiuwin'g: C = 3.0 - 3.5%, si = 1.4 - 2.2%, Mn = 0.6 - 0.8%, Sb = 0.3-0.65%, up to 0.3 % P r- and up to 0.12% S. The addition of antimony to gray cast iron.causes a conside able refining of the macrostructure of the latter. The microstructure of anti- mony-alloyed cast iron is characterized by a finely laminar pearlite and a uniform graphite deposition over the whole microsection field, while ferrite and cementite inclusions are not present at all. The addition of 0.25 - 0.35% antimonX to the -255 kg/nirr-, whi cast iron increases the pearlite microhardness from,196 to 245 ~~mm~e the microhardness of the phosphide eutectic is increased from 350 to 425 Card 1/6 85o95 S/121/60/000/010/011/015 Using Antimony-Alloyed Cast Iron Instead of Bronze A004/AO01 Moreover, the Brinell hardness of cast iron is increased from 197 to 229 kg/mm P The Increase in hardness is-effected on account of the alloying ability of the solid antimony solution. The bending strength limit and deflection of antifric- tion cast iron containing antimony decrease on the average by 18 - 20%, while the hardness increases by 10 - 15% in comparison wi th the initial cast iron. In a four-hour test series of cast iron containing up to 1.25% of antimony, with a lubricant supply of 3.75 cm3/hour and a specific pressure of 20 - 60 k&/cm2 it was found* that cast iron with an antimony content in the range of 0.30 - 0.65% possesses the lowest friction coefficient Figure 2: and wear..

ABSTRACT: The article extends, to: higher-order systems the results of the autb.or's work (see PMM, Vol 21, Nr 6, 1957) about the oscillations of a system with one degree of freedom. An approximation method of solution is used. A higher-order system is represented by the second order in the case of 2 roots lying close to the imaginary a.-do (e. g. , the case of two fairly long time constants of the controlled system and a number of short time constants of the controller). In this case the solution, for a unit signal at the input of the linear part and for zero initial conditions (transfer function), can be written as follows: Card 113 SOV/112-59-4-7478 Oscillations of Higher -Than-Second Order of the Leading -Characteristic . . . . it I t n- Xkt u0W h(t) = il e I + A,.e+ 7 Ak e kx3 where I Re and I Re )L,,. 19 1 Re)., I(k = 3, 4p . . . n).

Otherwise, the movement analysis can be conducted as in the case of the second-order system. Stability ranges of boundary cycles and the ranges of restricted, but not periodical, movements are determined in the article. AU example with a third-order system is used to show that the approximation method can yield qualitatively different results from those of the exact method.

In this case the idealized relay characteristic would possess a rectangular hysteresis cy~;Ie which is cut up in the medium range because of the existence of the zone of insensibility. Because of the un- avoidable delays in the switching process the real character- Card 1/2 Oscill&tions of a System Which Possesses a Relay With AO-22-1-5/1%z lesd%g Characteristic istic appears somewhat more complicated and possesses inter- sections and crossing-overs at the switching points. In the present paper the influence of these imperfections of real relays is investigated with the aid of the method of the phase plans. In the paragraphs 2-6 of the paper it is shown that.

Ther is a'capacitance coupling between the stages of the amplifier. The coupling capaci- tors are switched by keys. Upon closing the keys the input voltage at the stage is set at zero and charging of the coupking.capac~itor occurs. On opening the keys the capacitors retain the charge for a certain time and the entire circuit during this time has the properties of a dc-amplifier with direct couplings. Fine tuning of the amplifier takes place during the intervals. The basic data of the intermittent ampli fiers are given for-two systems. The amplification factor is 30 (1000), range of out put voltages 0- +50 V (0- �50 V),.and drift 0.5 mV.in.both cases. [Translation of abstract] 3 illustrationg-and,bibliography-cf- 2 title96 T.
