Abstract: Abstract of the Disclosure A method for processing heavy nonferrous metal raw ma-terials by heating and melting said raw materials in a mol-ten slag with the formation Or a heterogeneous melt consis-ting of a sulfide and an oxide phases. The melt is bubbled oxidized by injecting a gas containing not less than 35% oxygen at an intersity of about 200 to about 2000 m3 STP/h per square metra of horizontal section Or the melt with the effect that the melt is divided into a top bubbled part and a bottom calm part comprising a slag layer, a mattelayer and/or a crude metal layer, each of which is tapped separately. furnace for putting said method into effect is a shaft ter-minating in its bottom part by a hearth and having devices for tapping smelting products, whereas the top part 13 provided with orifices for feeding a charge and removing gaseous smelting products. The furnace has cooled side tuy-eres set at a level dividing the shaft into two vertical parts. The device for tapping slag from the bottom part of the slag layer is formed with a recipient communicating with the internal cavity or the shaft by means of a duct arranged below the tuyere level, but above the level of the matte inside the shaft. Said technological  sequence of operations and the furnace design provide a possibility of separating polymetallic raw materials by a single-stage process into smelting products and denuded slag. It is most effective to employ the present. invention for processing high-sulfur copper, nickel, copper-nickel and copper-zinc raw materials.

Abstract: J&J 959 ABSTRACT          BALANCED ENVIRONMENT WOUND DRESSING                   A non-occlusive, non-adherent dressing for wounds, the dressing comprising an imperforate (i.e. continuous) flexible film for contacting the wound, and an absorbent pad backing the wound-contacting film and extending beyond a substantial portion of the periphery of the film, the dressing having vapor transport capacity approximating that of intact human skin.  The absorbent pad removes wound exudate from the proximate area of the wound without the pad coming into contact with the open wound itself.  The final construction, comprising the film and absorbent backing, permits a measurable amount of moisture vapor to be transmitted (greater than 0.06 mg/cm2/hr), thereby greatly reducing the degree of maceration and other problems that may be produced by a fully occlusive dressing.

Abstract: ELECTROOPTIC INSTRUMENTS     ABSTRACT OF THE DISCLOSURE    Various embodiments of an electrooptic concept are dis-closed. The fundamental device is an oscillator comprising an electric circuit and an optical leg.  In the circuitry, a return beam of amplitude modulated radiation is converted to an electric signal, amplified, and used to modulate the drive in an LED type transducer wherein the electric signals are converted to a beam of optical radiation.  The beam is delivered to and returned from a reflective surface with waveguide means.  The device operates by converting the phase shifts in the optical beam which occur due to actual or effective changes in the pathlength of the optical leg to identical corresponding shifts in an electric rf signal, the latter being representative of the frequency of the rf oscillator.  The resonant frequency of the oscillator is a measure of the pathlength of the optical leg and this aspect of the present invention is discussed in various applications such as a fluid barometer, differential pressure sensor, fluid velocimeter, Pitot tube, shift position locator and temperature sensors.

Abstract: HIGH SPEED CAGE FLY-OFF STRANDER     ABSTRACT OF THE DISCLOSURE          A high speed rigid strander is described that has a rotatably mounted cage which includes a plurality of bobbin support members which are parallel to and angularly spaced about the axis of rotation of the cage.  Each support member includes a locking mechanism for simultaneously locking or releasing an entire row of bobbins, each of which is spaced from the axis of rotation and has its longitudinal axis oriented generally radially or at an angle normal to the strander axis.  Wire guides associated with each bobbin fly the wires off the bobbins under the action of external pulling forces without requiring the bobbins to rotate.  Fly-off is generally radially inwardly against the action of centrifugal forces and the wires are guided towards the strander axis and then parallel thereto so that the wires from all of the bobbins can be brought to an end of the rotating cage and wound about a core wire.  Also described is a loading and unloading system which can advantageously be used with the stranders of the present invention.
