Abstract: Abstract of the Disclosure In the method of the invention, the rectifier at a rectifier station is voltage-controlled and the inverters at the inverter stations served by the rectifier station are current-controlled,  More particularly, the reference input for the voltage controller of the rectifier is formed by means of a computer circuit on the basis of a fixed, predetermined current-voltage characteristic as a function of the respective, maximum possible current in the rectifier station.  In turn, a maximum value is formed for the reference input of the current controller of each respective inverter by means of a computer circuit on the basis of a fixed, predetermined voltage-current characteristic matched to the current voltage characteristic and the output capacity of the rectifier station, as a function of the voltage in the DC network.  The maximum value for the reference input of each inverter, in turn, is compared with a value for the reference input corres-ponding to the power demand of the respective inverter station in a minimum selection stage which releases the respective smaller value for the corres-ponding current controller.  When employing the above-described method of the invention it is, thus, possible to guarantee that each inverter station receives a predetermined power which depends on the respective output capacity of the rectifier station.

Abstract: ABSTRACT OF The DISCLOSURE         A high-carbon ferro-alloy, specifically ferrochrome or ferromanganese, is decarburized in a converter in which oxygen or air is blown from below into the melt together with a surrounding protective gas.  With the bath preheated to temperature somewhat higher than the melting point of the ferro-alloy, the oxygen is introduced at such a rate that its reaction with the chromium or the manganese locally superheats the bath, in a region well below the surface and spaced from the converter walls, to a temperature high enough to let the resulting oxides react endothermically with the carbon.  This reaction takes place in combustion zones believed to be localized in gas bubbles formed above the injection nozzles, the oxidation of the ferrous and nonferrous constituents occurring at the interface between the gas and the melt with formation of a very thin and highly reactive oxide skin around each bubble.          Some high-melting oxides of chromium or manganese may remain after the oxygen blow but can be reduced by blowing in powdered lime, after and possibly also with the oxygen, and by the deposition of solid or liquid reducing agents on the bath surface.  A minor fraction of the ferro-alloy may be added in solid form to hold down the bath temperature.

Abstract: ABSTRACT OF THE DISCLOSURE            The disclosure is directed to improvements in piercing and reeling mills, to facilitate the changing of mandrel plugs and mill shoes.  In piercing and reeling operations, mandrel plugs are supported at the ends of elongated mandrel bars, and work-pieces are driven over the mandrel plugs while being rotated, to effect piercing and enlarging, in the case of piercing mills, and to achieve roundness, in the case of reeling mills.  In each case, after processing a finite length of tubing, and while the work-piece remains on the mandrel, the mandrel is retracted, first stripping off the just-used mandrel plug, and then withdrawing the mandrel from the processed workpiece.  A multi-position magazine is provided for retaining a circulating supply of mandrel plugs such that, after each operation, the used mandrel plug may be returned to the magazine for cooling, and a new plug may be brought quickly into working position ready for the next operation.  The arrangement of the invention provides for expedited loading and discharge of the mandrel plugs, for greater efficiency in mill operation.

Abstract: Abstract of the Disclosure This invention relates to filterable microcapsules and to a process for preparing such microcapsules which are advan-tageous in the preparation of hot melt coating compositions for pressure-sensitive carbonless copy papers in that the micro-capsules are produced in an aqueous continuous phase and the microcapsules can be easily removed by the aqueous dispersion by vacuum filtering.  The process comprises preparing an aqueous dispersion of microcapsules containing an oil solution of a chromogenic material, the chromogenic material being an electron donor type color precursor, and the microcapsules having a primary capsule wall comprising a reaction product of hydroxy-propylcellulose and at least one oil soluble cross-linking agent for hydroxypropylcellulose.  The cross-linking agent is selected from the group consisting of the polyfunctional isocyanates, acyl chlorides, phosphoryl chlorides, sulfonyl chlorides, alkylene bischloroformates and mixtures thereof, the primary capsule wall being substantially oil and water impermeable.          There is then added and mixed into the aqueous dispersion of microcapsules a phenol and an aldehyde, the aldehyde being selected from the group consisting of acetaldehyde, formaldehyde, glyoxal, glutaraldehyde, fu?fural and mixtures thereof.  The mixing is maintained while the phenol and the aldehyde react together to form a condensation polymer, the condensation polymer being insoluble in the aqueous dispersion of micro-capsules thereby precipitating the condensation polymer on the primary capsule wall as a secondary capsule wall.

LANDT           ABSTRACT OF THE DISCLOSURE        A blind fastener assembly includes, in one embodiment a pin, an  expander and a sleeve.  The pin and expander may in-clude, in one configuration, mating threads for drawing the sleeve axially over the expander toward the blind side of a work-piece, or the pin may be a pull-type wherein the portion of the pin opposite from the blind side end has pull grooves which are adapted to be gripped by a conventional pull gun.  The sleeve is a tubular member with a portion of its  length having a normal radial thickness and a portion having reduced radial thickness comprising a reduced outer diameter over a portion of its axial length and a counter-bore along the same axial length adjacent one end of the sleeve.  The expander extends through aligned holes in the workpieces and has a tapered nose surface proximate the reduced thickness portion of the sleeve.  When an axial force is exerted on the pin, the reduced thickness portion of the sleeve 18 forced over the tapered nose surface on the expand-er toward the blind side of the workpiece and is expanded in diameter.  The tapered surface of the expander also deforms and dependent on the overall joint thickness, with a large diameter bulb forming for a maximum joint thickness and a smaller diameter bulb being formed for a minimum joint thickness.
