P/002/60/000/002/003/004 A223/Ao26 Six Years of PAS Institute of Basic Technical Problems forming an institute with such a wide non-specialized field of activities proved unfounded, since 1) the present-day complex research very often deviates from the traditional division of science into specialized fields and 2) the admin- istrative section of the Institute Is small and would have to be considerably expanded, involving greater costs and more employees, if the Institute were di- vided into 4 to 6 specialized units. The Institute, which has 8 scientific sta- tions organized on a federative basis, deals with three subjects, i.e., mechanics, electrical engineering and industrial physics, In the beginning the Institute experienced considerable difficulties due to the shortage of adequate premises, With the new building this problem has been solved to a certain extent, but a lot still remains to be done so as to enable workers of the Institute to carry out their work which is both theoretical and experimental. The Institute pub- lishes five periodicals which are also well received abroad, A graph showing the increase in the personnel of the Institute and a graph showing the Increase in the scientific equipment of the Institute are included in the article Clos- ing his speech, Malecki also pointed out that international cooperation has been developed and that many of the results of research carried out by the Institute have found practical application In the national economy- Professor J Groszkow- Card 2/18 P/002/6o/ooo/ooVoo 3/cc) a Six Y~ars of PAS Inst.Itu,,e of Bazi,_ Problems A22YA026 sA_1 described the scllentifi_- activ.,Tie,~ of h=- Tn_-t1t-.1*,~ in Th~ fi~-!,. of ele- trical engineering, whicn is carried o,,it ty thr~c- departments, viz , Tne Zak-l&d Teoril Lqcznok1 (Department of Commun-ication Th,~ory), Zaii_-aa El-e-trotechnilci (Electrlcal Engineering Departrr,,:-nt) and the Z&tdA-d EleEt-oniii_i (Electroni_~s D,-~p.qrtment).

The De- partment which has about 200 workers publishes the following monographies; "Zagadnienia Techniki Pal Ultrakr6tld2h" and "Zagadnienia Elektrotechniki Teo- retycznej". The Electrical lDngineering Department started as an auxiliax-j sec- tion of the Division IV in 1954 under Professor P.J. Nowacki. In January 1959, this section was included in the IPPT with Doctor M. Na1qcz as its head. The work of this Department concentrated on magnetic c1rcuita. Based on the orig- inal so-called "first har-monic"method by Professor P.J. Nowacki, the theoret- ical explanation of the compensation mechanism of errors in power test trans- formers was worked out (Doctor M. Nallez) as well as the theory of magnetic circuits fed by direct current and on modulation in transducer circuits (Docent R. Ladzifiski). In cooperation with the Zaklady Wytw6rczy Aparatury Wisokonapiq- ciowej A-1 (A-1 High-Ten-, - -pparptus Plants) the production of the first Card 5/18 P/002/60/000/002/003/004 A223/AO26 Six Years of PAS Institute of Basic Technical Problems series of these devices has been started. Doctor M. Nal~cz. Master J Kulikow ski and Engineer J. D4bkowski designed a number of sensitive magnetometers which aroused great Interest at the conference in Leningrad in 1958, Master H_ Zlo- mecki designed a magnetometer with a range of 5,000-25,000 gauss and equipped with the Hall sonde. The Hall effect was also used in the design of a d-c test transformer. Master S. Topinski developed a thermometer with a range of i8-420C and with the senser built in at the end of the thin needle, which is used in surgery. The Pracownia Malych Maszyn Elektrycznych (Laboratory of Small Electric Machines) headed by Docent T. 611wifiski, developed a number of proto- types of a-c electric motors with continuous regulation of speed (Master j. Borkowski). The blueprints of a special type of induction motor with the stator fed by direct current (Master J. Kyparisis) have been completed, while i 400-kv, 2-4m electrostatic generator (Docent S Nowiokl) 19 under construction. Docent A. Gbrski and Master J.. Moszczyfiska worked on the problems of fuel elements The purpose of their work was to develop electrical elements which would allow the replacewent of chemics.1-fuel energy by electric energv. During tt.Q 5 Years of existence the Electrical Engineering Dppart,men~ published 60 scientific Card 6/18 P/O(P-/60/000/002/003/004 A223/Ao26 Six Years of PAS Institute of Basic Technical Problems works In Poland and abroad. The main task of the Electronics Department, which was founded in 1952 and is headed by Professor J, Groszkowski, was to carry. out research on semi-conductor and ferromagnetic materials. The work is car- ried out In the Department's six laboratories. The Praccown-la - materia,16w p6lprzewodnikowych (Laboratory I - semi-conductor materials) carried out re- seqxch on the chemistry of semi-conductors (under Master Z. Soltys) and on the purification of semi-conductor materials and monocrystallization (under Master Z. MaJewski), The Pracownia II - elementbw p6lprzewodnikowych prostuj5cych (La- boratory II - semi-conductor rectifying elements) under Master Z. Majewski. worked on the technology and theory of germanium and silicon rectifiers, photo- diodes, phototransistors and worked out the method of measuring the electric properties of germanium and silicon. The Pracownia III - elementbw p61przewod- nikowych wzmacniaj4cyh (Laboratory III - semi-conductor amplifying elements) under Master W. Rosifiski worked on germanium and silicon transistors. The Pracownia IV - pb1przewodnikowych element6w oporowych (Laboratory IV - semi- conductor resistanceelements) worked on thermistors and thermistor materials- The Pracownia V - material6w magnetycznych (Laboratory V - magnetic materials) Card 7/18 P/002/60/ooo/oo2/003/004 A223/AOr26 Six Years of PAS Institute of Basic Teehni.cal Problems under Professor A, Smolifiski, completed research on magnetic lag in silicon steels and on the technology of fer-rites with rectangular hysteresis loop for computers, The Pracownia VI - uklad6w przyrzad6w pblprzewodnikowych ( 'Labora- tory VI - semi-conductor device systems) works on the application of diodes and transistors under Master St, Siekiersk-i, During the period 1953-19.59, the Electronics Department published 53 communications, g2 articles and 6 textbooks. The Department, also organized the Krajowa Konferencja Ferrytowa (National Fer. rite Conference) held in May 1959. Master Brochocki and Master Kobus take the credit for their work on methods of purifying germanium and on the methods for obtaining single crystals with low resistance. Master Z. Majewski, Master Bro.- chocki and Master Z. Soltys take the credit for their work on the problems of silicon microivave diodes on 3--cm waves. Master W.

During the period under review the Department also organized 4 international scientific conferences, the sub- ject of which were dynamics of gases and molecular aero-dynamics. A total of 37 original works were presented at these conferences, of which 21 were Polish and 16 foreign. Four members of the Department obtained the title of Candidate of Sciences and 2 that of Docent. The workers of the Department took part in various international congresses, including the Congress on Theoretical and Applied Mechanics held in Opatija, Yugoslavia in 1958. Foreign scientists showed interest in the results of scientific work of this Department. Twelfe well-known foreign scientists also took part in the Department's conference held In Augustow in 1959. Scientists of the Department were also asked to give lectures in the USSR, China and USA. The Department of Metals was founded in Krak6w in 1953 and has today 32 members. During the 6-year period the Depart- ment published 92 works, of which 13 were also translated into Russian, Czecho- slovak, Hungarian and German. The workers of this Department also presented their original works at various international conferences, including the confer- ence In honor of G. Agricola held in 1955 in the GDR, Conference on the problems Card 13/18 P/002/60/000/002/003/004 A223/026 Six Years of PAS Institute of Basic Technical.

The activities of the IPPT's De- partment of Metals during the past 6 years Included three fields, I.e., 1) theo- retical metallurgy; 2) theory of plastic deformation of metals and 3) basic problems in the possibilities of utilIzIng domestic raw materials. The Depart- ment also organized scientific meetings and promoted cooperation with scientific institutions in the USSR and the GDR. The research program included 1) change in the process of rectification allowing for the production of 99.99% % zinc; 2) construction of the first industrial cadmium rectifier in the world; 3) pro- duction of pure metals, such as oxygen-free copper; 4) thermodynamics of ion- structure solutions, 5) plastic deformations of metals; 6) method for deter- mining anisotropy of mechanical properties; 7) new non-ferrous metal alloys card 14/18 P/002/60/000/002/003/004 A223/AO26 Six Years of PAS Institute of Basic Technical Problems (silicon bronzes, low-copper brass and zinc-manganese alloys) and 8) original method for determining micro-seggregation in industrial metals. During 1956-1959, the Tndnnendent Astronautical Laborato headed by Professor K. Zarankiewicz, carried out research on various astronautical problems, such as the structure of the atmosphere, mechanics of rSSI",flight and the utilization of nuclear energy for rocket propulsion's ProfessYr I. Malecki reported on the achieve- ments of the IPPT in the ld of industrial physics, which is dealt with by the Zak-lad Badania Drgafi (Department for Research on Vibrations); Zaklad Analogil (Department of Analogy) and the SamodzIelna Pracownia Techniki Izotopowej (In- dependent Laboratory on Isotope Ehgineering). The Department for Research on Vibrations (Professor 1. Malecki) carried out research on mechanical, acoustic and electric vibrations. The team under Doctor Koltofiski carried out tests with the application of ultrasonics In geological research. The device for this purpose named "petroskop" aroused great Interest at the Moscow exhibition, Docent Filipczyfiski developed a "betonskop I' which is used for checking concrete structures. It is expected that this "betonskop" will become an important ex- port article next year. The team headed by Master Wehr carried out research on Card 15/18 P/002/60/000/002/003/004 A223/AO26 Six Years of PAS Institute of Basic Technical Problems the use of ultra-sonics in the research on physical properties of insulating materials, plastics and liquids. Such methods have already been applied it. industrial-porcelain plants and it is expected that they will soon find appli- cation in the chemical and rubber industries. The Department also developed, in cooperation with the Zaklad Elektroakustyki Politechniki Warszawskiej (Depart- ment of Electro-Acousties of the Warsaw Polytechnical Institute), an ultrasonic defectoscope, of which 200 have already been exported. Due to the new technol- ogy of ultrasonic control considerable savings were achieved and production increased in plants such as the Zaklad &Ierezewskiego (Plants "imenia Swiercze- wski") in Elblqg and "Ursus". The specialultrasonic devices designed by Do- cent Filipezyfiski and Master Pawlowski are used for testing railroad tracks and carriage axles. The active application of ultrasonic methods is carried out under the supervision of Master Le�niak. The most important &chlevement in this field is the construction of a generator, which will allow an expansion of work on the active application ofultrasonic methods in chemistry and metallurgy. The laboratory headed by Docent Pajewski is the only Polish station which produces special piezoelectric converters. Doctor Koltofiskl carried out work on problems Card 16/18 P/00--P/60/000/002/003/004 A223/AO26 Six Years of PAS Institute of Basic Technical Problems of stereophony. Research on the acoustic structure of the Polish language Is carried out by Docent Jassem in a special laboratory set up for this purpose. Docent I. Kacprowski carried out research on problems of telephonometry and on the transformation of electric vibrations into sounds. The laboratory headed by Professor S. Kaliski produced some outstanding results in the field of dynam- ics of stressed and non-stressed structures and on various characteristics of anisotropy. To the team, headed by Professor S. Ziemby, goes the credit for re- search on wear and fatique of materials and for the work on low-frequency vibra- tions. Although the work in the field of electric vibrations made no spectacu- lar progress, the work on high-class molecular frequency stabilizers, carried out by Doctor S. Hahn, is extremely valuable. The task of the Department of Analogy (Head Doctor Czarnecki) is to transform mechanical, electric and acous- tic phenomena, research on which is carried out in other IPPT's departments, In- to mathematical terms. The Department concentrated, therefore, on developing analogue machines. Master J. Karpinhki designed an original analogue machine for meteorological. purposes. A modem transistor machine for analogue analysis is under construction. Master Kanczewski carries out work on modelling with Card 17/18 P/002/60/000/002/003/004 A223/AO26 Six Years of PAS Institute of Basic Technical Problems the use of so-called electrolytic grids. The Independent Laboratory for Iso- tope Engineering which is headed by Docent M. Radwan was founded 3 years ago. The laboratory concentrated on research into the phenomena of radiation in in- ternally non-homogeneous bodies. This work served as the basis for the develop- ment of defectoscopy by the use of cobalt, Irldium and cesium. This laboratory also took active Dart in the introduction of various isotope methods in industry; V, especially fruit-bearing was the cooperation with the "Warszawa" Huta (Metallur- gical Plant) and ffEnergomontai". A saintillating spectrometer was also designed. The isotope method for checking the flow in electrolytic baths was also mastered and introduced by the Aluminum Plant in Skawina. There is also close coopera- tion with the Institute of Acoustics in Moscow, the Polytechnical Institute in Dresden and the Institutes of the Hungarian Academy of Sciences, There are 2 figures and 4 photographs.

VOL 14 10 English summaries) The author of this paper derived a th tfdaviled. vary NOT- 1953 beams in a previous (unavailable) W tvn Ina. ork EM Techn. Lotn. 6 (1947)]. His theory differs that given' 101M meh. by VIAov [Akad. Nauk SSSR. Prikl. Mat. 8,361-394 (1944); these Rev. 7, 142], mainly in taking into account the so-called self-equilibrating stresses; Vlasov's theory neglects these stresses completely. In this paper the author. presents the application of his theory to a particular case. Yhe beam under consideration is a cylindrical shell cut lengthwise, which makes the crosa-section open. The beam is fixed at one end and uniformly loaded. The assumptions are as follows: 1) the cross-sections remain plane; 2) the t rigidity of the wall can be neglected; 3) the existence of a i -plane state of stress in the wall; 4) the Poisson ratio: psetido equals zero. The author reduces the problem toaboundary-, value problem with four unknown functions and solves it. Considering bending and tersion separately. T. Lerer.
