Abstract: ABSTRACT OF THE DISCLOSURE          A method for producing stainless steel in a top-blown molten metal vessel having a hot metal charge to form a bath.          The method comprises top blowing from a lance oxygen and/or a mixture of oxygen and inert gas onto or beneath the surface of the bath while introducing a low flow rate inert gas to the bath from beneath the surface thereof during said top blowing.  The ratio of oxygen-to-inert gas is decreased progressively during top blowing.  The relative flow proportion of top-blown gases and bottom-blown gases remains substantially the same throughout the process.

Abstract: ABSTRACT A burst signal generating apparatus includes a modulator circuit for modulating a carrier wave of an intermediate frequency with a modulating signal.  It also includes a frequency converter circuit for converting the output frequency of the modulator circuit into a radio frequency.  An amplitude control unit responsive to a burst control signal controls the amplitude of the carrier wave of the radio frequency.  A switching circuit responsive to the burst control signal causes switching of the carrier wave of the inter-mediate frequency.  The invention permits ready suppression of the carrier wave during the pauses of burst signals.  A reduced number of PIN diodes can be used in the high frequency region.  The invention also permits the use of a class C amplifier, which is highly efficient, yet has a wide dynamic range and is virtually free of carrier wave leaks.  The apparatus of the invention consumes little power and is compact.

Abstract: ABSTRACT       The present invention relates to a method and to an apparatus for acoustic supervision of the adjustment of a light bundle with respect to position and/or direction.  A measuring surface lying in the beam path of the light bundle is divided into sectors.  Apexes of centering angles of the sectors define a rated position.  Light components of the light bundle incident into the individual sectors are measured opto-electronically as a measure of the positional deviations.  Oscillations are generated for the individual sectors.  Respective parameters of the oscillations are modified dependent on the measured positional deviations, and the modified oscillations are made audible as measuring tones.  For the directional adjustment of the light bundle, the light bundle is focused onto the measuring surface whereby apexes of the centering angles of the sectors define the point of penetration of the rated direction through the measuring surface.

Abstract: MOBILE MINERAL PREPARATION PLANT               ABSTRACT OF THE DISCLOSURE        An apparatus for separating granular material such as crushed coal or ore that includes particles of different specific gravity.  The apparatus includes an elongated frame defining a receiving chute and a dis-charge chute,  A plurality of hydraulic cells are sup-ported in tanden on the frame, each cell including a wave chamber, a screen forming a material supporting floor submerged in the wave chamber, plungers for cyclically raising and lowering the water level in the wave chamber and a refuse bin adapted to receive heavier particles that are separated out in the wave chamber and that col-lect above the screen.  The wave chambers define a flow channel extending from the receiving chute to the dis-charge chute and adapted to contain a suspension or slur-ry of the crushed particles.  The plungers for each cell operate in a cooperative manner to generate a wave which progresses from the upstream end to the downstream end, the plungers having a decreasing stroke so that some re-inforcement of the wave is provided but the amplitude diminishes gradually toward the downstream end of the flow channel.  With this arrangement, the hydrodynamic separation proceeds from a relatively rough level to a relatively fine level at the downstream cell.  According-ly, the downstream cell has the capability of separating out even those particles relatively close in specific gravity to that of the desired particles.

Abstract: RCA 83,456 Abstract An amplifier applies turn-on bias to the gate electrode of an output field-effect transistor in response to a first level of an input signal applied to the amplifier.  A switched power source supplies operating current to the amplifier for developing the turn-on bias when the amplifier input signal is at the first level.  A feedback-controlled bypass circuit diverts a portion of the operating current from the amplifier during an initial turn on period and gradually reduces the magnitude of the diverted operating current as the output transistor turns on thereby producing a "soft" turn-on of the output transistor so as to minimize a potential for creating radio frequency interference in nearby RFI sensitive devices such as the tuner in a television or radio receiver. Complementary circuits include dual current supply and diversion circuits providing controlled rise and fall times for complementary field-effect output transistors.

Abstract: ABSTRACT OF THE DISCLOSURE     A dual flow air ring is used to cool the exterior surface of thermoplastic tube after the plastic is extruded from an annular die.  The surface of the wall forming the divider between the upstream and downstream flow paths which confronts the extruded tube is shaped to include a region of decreasing diameter in the direction of tube travel so that the flow path for air issuing from the lower discharge formed between the extruded tube and the surface is caused to converge.  This converging flow stabilizes the tube thereby permitting more vigorous cooling and consequently higher production rates.
