It consists of less than 0.5% by weight of C, less than 2% by weight of Si, 20 ~ 30% by weight of Mn, and 0.005 ~ 0.04% by weight of N and the balance of iron and impurities, wherein the following relationships between the amounts of C and Mn are simultaneously satisfied Mn (%)>  16 x C (%) + 18 Mn (%)> -12 x C (%) + 21.5.          The steel described above is heated to a temperature of less than 1220 °C, and then hot rolled.  A finishing rolling temp-erature is maintained to be less than 800°C + 400°C x C (%) depending upon the amount of carbon.  After cold working the nonmagnetic steel has a permeability of less than 1.1.  This method enables the production of steel having the above proper-ties, at a low cost.  This steel is suitable for use as guide structures, and reinforcing steel of railroad beds of the floating type high speed railway, structural members for con-structing fusion reactors, various electrical components, etc.

Abstract: CHOPPER TYPE, PROPULSION SYSTEM WITH LOW SPEED ELECTRICAL BRAKING CAPABILITY FOR TRACTION VEHICLES         Abstract of the Disclosure A propulsion system for an electrically driven traction vehicle includes a chopper, a d-c traction motor, and means effective when the system is operating in a motoring mode for connecting the chopper in series with the armature and the field windings of the motor to a d-c electric power source that includes a filter capacitor.  Cyclically operative means provides periodic gating signals for alternately turning on and turning off the chopper, and it can be smoothly changed from a constant frequency, variable pulse width mode to a variable frequency, constant (minimum) off time mode so as to vary the "duty factor" of the chopper over a wide range extending up to 100 per cent on time.  Brake set up means is operative in response to a motoring-to braking command for reconnecting the chopper in parallel with the motor and the filter capacitor and for reversing the polarity of the con-nection of the series field winding relative to the armature.  In response to this operation of the brake set up means, current in the field of the motor is momentarily boosted, and an extended chopper turn on signal having a duration substantially longer than that of the aforesaid periodic gating signals is supplied to the chopper to ensure that it turns on and conducts armature current to begin the braking mode of operation even if the command happens to take place at low speeds when the electromotive force of the motor is corres-pondingly low.

Abstract: METHOD AND APPARATUS FOR PRODUCING HIGH           PURITY SILICON FROM FLAMES OF SODIUM               AND SILICON TETRACHLORIDE                  ABSTRACT OF THE DISCLOSURE          Vaporized silicon tetrachloride is mixed with vaporized sodium in an exothermic reaction producing liquid silicon droplets and gaseous sodium chloride which are subsequently separated in an efficient manner.          Separation of the silicon from the salt by-products is performed by a jet impaction separation technique wherein the products of the complete reaction between sodium and silicon tetrachloride are made to exit from a small hole in the reactor into a region held at a pressure less than half of the reactor pressure.  A supersonic jet is thus formed which impinges upon a surface so that the direction of flow of the gas changes abruptly.  The silicon droplets, however, are carried by their large forward momentum onto the surface where they are deposited.  The salt vapor is then made to flow away from the depositing area and is passed over cooled surfaces where it is made to condense.  Modi-fications of the basic technique allow the silicon to be collected in a variety of physical configurations including pellet form, crystal form, sheet form and ingot form.

In order to reduce the dead times and to remove or, respectively, keep as little as possible negative influences occur-ring during the measuring of different test piece material and at distance variations without adversely affecting the signal/ noise ratio, it is proposed that those parts of the exciting coil and/or receiving coil designed for current conducting be made of resistance material which is suitable for struc-tural elements embodying electric resistors, and which material will not essentially obstruct the current flow during the exciting phase of the current, and after termination of the excitation will rapidly reduce the energy stored in stray and coupling fields.
