A221/A126 grains. After this treatment the grains are washed first in water and afterwards with diluted sulfuric acid. Fatty acids adsorbed are now converted into fatty acids hard to solve. Fatty acids are not wetted by water, therefore zircon grains are becoming hydrophobia. From the mixture so prepared, titano-magnetite, ilmenite and garnet are removed by magnets and the remaining grdins diverted into flotation chamber. Before flotation this mixture contained about 70% zircon, 14% rutile and 14% of other opa4ue minerals. After flotation the concentration of zircon is increased to 97% with 87% efficiency. Obtaining ilmenite concentrate. From the sea sands treated with magnetic enrichment, a mixture of ilmenite and titano-magnotite was obtained. This mixture was roasted in CO atmosphere at 7000C. The product of this treatment was subjected to another magnetic enrichment from which two products were obtained, The titano-magnatite and ilmenite with 50.25% of T102. Monazite separationt In sea sand samples 0.1% of monazite wus detected. In the concentrate obtained there were 90-97% of monazite, 1.5% zircon, 0.9% of garnets and 6.631% of opaque minerals.

The method of measuring small changes in electron concentration In plasma by the higb-frequency resonance method with an apparatus working in a frequency band of 3 kMc was verified. The authors stated that the initial relations of the given method are valid with sufficient accuracy even. in this frequency band. The authors. thank V.

The position Is not so satisfactory concerning the manu- facture of welding tractors for are-welding with the uard 114 fluxes uT-125C and IDSh-500, and much equipment and SOV/1 25-59-1 u-7/1 6 The Present itate and the Outlook for the 4elding industry in _--0- land assistance have been imported from the uDR and the USSR, particularly from the institut elektrosvarki imeni Ye.0. Patona tInstitute of blectric iielding Ime- ni fe.0. Paton). In the field of contact electric welding only 2 models of spot-welding machines have so far been built k20 kilovolt/amps); gas-welding was widely used in Poland before the war and manufacture of this equipment is now limited to one plant, while the problem of the production of automatic oxygen cutters is still being worked on. Oxygen, acetylene, welding wire and fluxes are largely of domestic ori- gin anj production is being steeped up: from IC mil- lion m in 1945 to 40 million m in 1158 koxygen and from 2,000 tons in 1945 to 5,uOO tons in 1958 kacetylene). There is a shortage of electrodes in the electric are-welding industry, which will conti- n,je for another 3 years or so, there being at present no e3ectrode factory In Poland, and the manufacture of fluxes is limited to certain types sui!ed to the uard 2/4 welding of low-carbon steel. e4elding processes in-v,:~!- 30V/1 25-59-1 U-7/1 F The Present State and the Outlook for the tielding industry i:1 o I and ving the-use of protective gases - argon and ~0_ are still in their teething stages, particularly since the present dom-stic supplies of the gases are not pure enough for this purpose. considerable pro- gress has, however, been made in the training of welding experts and the raising of technical qualifi- cations: this reponsibility lay first in the hands of the Institute of Welding in &atowice, later vith the i'sentr professional'nogo obucheniya kCenter of :ro- f essional -i-raining) , and f inaily vith the Ministry of Education. in the last 2 years a check of weiders' qualilications has been carried out, as a result of which the standard has risen; in addition, about 250 engineers specializing in welding ilave graduated from polytechnic schools. A brief review is then given of various institutions connected with welding in Foland: the institute of velding, the first and for many years the only one in the country, founded in .,arch 1945, and the sub-divisions of it in the Card 3/4 experimental center at the udansk shipyards, the SOV1121-)-~9-' -71,16 The iresent ~I-ate anc the Outlook for the eielding Industry in 'C- land Otdeleniye tekhnologii svarki v Vheleznodorozhnom in stitute ~Department of oielding I-echnology at the Railroad institute), and the svarochnaya latoratoriya v Institute sl~-roitel'noy Iekhniki kWelding aborator,) at the institute of -'onstruction fechnology . The first-na.med, based on .~liwice and a member of the in- ternational institute of aelding, concerns itself with the main, general problems of this sphere of industry) while the sub-divisions are engaged on more speciali- zed, technical matters; there are also 5 departments of welding in 5 polytechnic institutes. in the near future the following main tasks are to be solved: the raising of the output of gas and fluxes, -'.,e moder- nization of welding equipment and the carrying-out of further, extensive research work.

This research was under- taken because of lack of "CTP" graphs applicable to steel made in Poland from which the structure and hardnesB of steels affected by heat can be estimated with sufficient accuracy, fAbALtracter's note: The meaning of the "CTP11 abbreviation is not revea J.

For calculation 3 t~he arc linear heat power q/v, the coefficient n = 0.75 was chosen for hand welding, and for automatic welding;~ = 0.90.

In order to secure identical struc- tural properties, all samples were annealed before welding. Welded samples were metallographically ex:amined and their hardness measured by Vickers' method. Upon examinntion of obtained datait was reveal- ed that as the arc heat capacity diminishes, the hardness of steel affected by heat increases along with carbon content in it. As the hardness of the intermediate sphere should not exceed HV 300, for welding steel with higher carbon content, thicker electrodes and a current of higher intensity should be applied and at the same time welding speed reduced. Thicker steel tends to ha-rden in the sphere of heat influence, therefore, in order to avoid this, the data obttn- ed, should be multiplied by a suitable coefficient listed in a table, The article ends with a practical example on how to esti-mate the are current intensity for fillet welding of a 20 mm thick SLeel sheet containing 0.4% C, with welding speed 7 m/hr (0.19 cm/sec), are voltage U = 28 V and-/~ = 0.75.

At high temperatures the passivating agents react practically Instantly with the surface of the molten metal drops during the pulverization process. If a gas jet acts as a pulverizer (compressed air, nitrogen, etc) then the passivat- Ing agent, in the form of vapor, fine drops or gas, must be uniformly distributed in the pulverizing gas.
