FrantAek, Engineer D006/Dl02 TITLE: Development of inflatable concrete forms. PERIODICAL: Technick4 noviny, no. 16, 1962, 6 TEXT: A compound, inflatable core for cavity concreting was developed by the na'rodnT podnik Fatra (Fatra National Enterprise) in Napajedla to rep-lace the conventional one-piece inflatable core which is too expensive. The development was based on an invention of Fojta and Kadlec. The new core consists of one or more inflatable bladders of PVC foil and a shaping casing of polyamide fabric. So far, cores for concreting manholes with a level bottom, inlet catch basins, and cylindrical sewers have been designed. The Olcresni podnik Znojmo, zivod plasti- lca'~sk4 vy'roby v Hru's'ovanech'nad Jevisovkou (District Industrial Enterprise, Znojmo, Plastic Products Plant in Hru%s'ovany on Jevi'govka) started pilot production in January 1962. During 1962, the development will be aimed at replacing the PVC- foil bladders by bladders from light rubberized fabric or a similar material for use during winter, and for noncircular cross-sections.

This method which combines practical measuring with.theoretical calculation, uses the data obtained from measuring the dimensions and phase of thejattern of the basic double dipole for calculating the horizont and ver- tical radiation pattern of.the entire antenna system. The figure for determining antenna parameters for the calculation of horizon- tal radiation patterns, is shown in Fig. 2, that for calculation of vertical radiation patterns is shown in Fig. 3. The field strength of a double dipole is E Em COS2 ac CV/mj I where 4 is the azimuth angle.+ Considering that He phase angle Y,,, varies from A =01 to o(= 900, and-that -IN is the phase angle'when di- Card 115 86 Z~O 9/0/0'22/009/002/005 Calculation of radiation...

Phase cQmpensation effects the improve- ment of both the radiation pattern (roundness) and the impedance proportions. The gain of an antenna system can also be calculated with the measured gain of the basic double dipole andits radia- tion-pattern. When the energy supplied to the entire antenna .system is Ps, and the antenna has a total of m radiators, of which the portion n radiates into one direction, the energy supplied into one-direction is P --a n.

In conclusionthe authors state that this method of cal- culating antennadatternsand gains is m6re convenient and precise than former cale atioft methods; however, the calculation or an antenna pattern still remains a rather tedious operation.

It is shown that arbitrary antenna systems can be compiled from full-wave double dipolesq and show considerable advantages over other antenna types. Theyhave very great operational stability, considerably wider bands, and very small standing wave ratios. Coupling ratios are very fa- vorable and do not complicate the adjustment. The entire system can Gard 1/2 Z/03 61/022/012/007/009 Z/03 61/022/012/007/009 Antenna systems with D291YD306 be assembled and adjusted at the plant, reducing the operations to be performed at the tower to mechanical assembly and calibration tests. Modern feed systems allow efficient matching to the feeder* Many design problems of TV antennas for the IIIrd band, discussed in this article, are also common to TV transmitter antennas for the Ist and IVth band.

T M i The article describes the origin, appearance and countermeasures of FM distortion in ultra-short wave transmisqion, observed at the "Tatry" trans- mitter In Velkk Slhvkov near Poprad. The transmitter operates on 69.4 Mc, with a frequency.shift of t 50 kc, and has a capacity of 1 kw. The directional an- tenna with an effective height of 25 m consists of 6 half-wave dipoles with a re- f 4- sonance reflector (Photo 1). It Is designed as a temporary trnnamitter or the Tatra Mountain region and will be transferred In 1961 to the RAlovA Hola Moun- tain. The authors explain the possible deviations of thq transmitted signal due to contrary topographical features of this region. A horizontal transmission dia- gram of the "Tatry" transmitter is given in Figure 9. Tests showed that the de- viation increases with increasing frequency shift, higher modulation frequency, and ratio between direct and reflected waves. The rather low effective height of the antenna, the vertical polarization, other antenna towers and high buildings card 1/4 21186 Z/014/60/000/011/ooa/010 Frequency-modulation distortion... A20.5/A126 have additional unfavorable influences. These influences can partly be eliminated by directional receiver antennas, in case the direct and reflected waves come from different directions. Time deviations of 6 - 8jAseo can be suppressed by proper rr(-.Iver or discriminator tuning, provided the field strength is sufficient. In com~lusion, the author states.that topographical features can considerably impair the quality of FM reception, a factor which*should be considered the mountainous regions of Slovakia.

Infantile mortality must be decreased and all measures for increasing the population stimulated. Infant mortality in Bohemia and Moravia is about 10 per cent. In the Vodnamy district it is as high as 15 per cent, that is higher than among the negroes in the UI.S.A. 20 years ago. The causes are as follows: (1) In mountainous and remote distrites there is a complete lack of continuous welfare super- vision for mother and child; (2) midwives in country districts are rostly a generation behind the times, especially as regards child-welfare. The author, who is district medical officer for Vodnamy, instituted a special camraign for the improvement of welfare services. He organized courses for midwives, public health w,-rkers and nurses in maternity homes, edited a booklet 'Instructions for mothers' dealing with pregnancy, labour, post-partwn period and the feeding and care of infants and created an orga- nization for infant welfare and pre- and postnatal care of mothers.

The concentrations found were be'tween o.00009 and 0.0014%. One hundred vorkers in this plant were examined before and after the shift. The concentrations of CO Hb. in the blood (examined by the method of Wolff-Skramovsky-Srbova) were higher after the shift than before. The blood count showed on the average higher values of RBC than are generally found In workers in other sectioas of industry. These values were higher after the shift than before it.

PraQue, Pracovni Lekarstvi, Vol 18, No 9. Nov 669 PP 393 - 399 Abstract juthors' English'summary modified '7: The effect of wood dust is mechanical, chemical, and physilcochemical. The diseases caused by wood dust are varied, and may involve many organs, but it is the skin that is affected most frequently. Usuaily the biological effect is due to some substances contained in wood, which is true especially of -- tropical woods. The dis- eases induced by wood dust are either due to its primary toxic effect, to allergy, or to ~ general damage caused by the dust. A case of two woodgrinders is described; it seems that the wood which they handled contained some 2% fren silica, which induced lung fibrosis.
