Title: Method and apparatus for treating metal
Inventor: WILSON WILLIAM G
IPC: F27D3/18

Granted: 1978-11-14
Abstract: ABSTRACT OF THE DISCLOSURE             The apparatus disclosed is intended primarily for use in practicing the disclosed method of introducing additives into a molten metal bath contained in a typical ladle or vessel mounted in an upright position with an open mouth at its upper end.  The total apparatus includes mechanisms which may be conventional for producing a continuous stream of a fluidized mixture of a carrier gas and solid additive material in particulate form. Various solid additives are introduced into molten pig iron or steal, including aluminum, magnesium, calcium carbide, rare earths, columbium, boron, molybdenum, and many others for such purposes as deoxidixing, desulfurizing, alloying, controlling grain structure, etc.  The novel portion of the apparatus includes a discharge ?ube mounted in upright attitude and extending down into the open mouth of the vessel.  The upper inlet end of the tube is flow-connected to the source of the fluidized mixture and the lower discharge end is spaced a selected distance above the bath to eject a free stream of the mixture down toward the bath.  The velocity of the stream is so chosen that the energy of the solid particles is sufficient to cause them to penetrate into the bath and the energy of the gas is insufficient to enable it to penetrate into the bath so that it spreads out radially.  To prevent the gas from flowing over the whole surface of the bath and causing violent disturbances and splashing, a tubular shield is arranged to surround the stream and extend into the bath.  The shield confines the gas to a minor portion of the surface area of the bath and causes the gas to reverse direction and flow out of the open upper end of the shield.

Abstract: ELECTRICALLY PUMPED, SOLID-STATE DISTRIBUTED FEEDBACK                LASER                 ABSTRACT OF THE INVENTION         An electrically pumped, solid-state laser device having a grating or physical periodic structure in a region, or adjacent a region, of semiconductor material that functions as a light wave guide.  The spacing of the perturbations of the periodic structure are selected to be an integer number of half wavelengths of the desired laser wavelength.  The electrically pumped, solid-state laser device can be a single heterojunction device or a double heterojunction device.          Both devices are formed by a process which provides for formation of the periodic structure prior to formation of the light guiding layer or region.  Due to this process a periodic structure having a desired spacing and substantial depth is produced, which structure produces Bragg Scattering which couples and reinforces light traveling through the light guiding layer in both directions in a coherent manner such that reflections are in phase, thus allowing laser operation in the absence of discrete end reflectors.

Abstract: Abstract of the Disclosure The embodiment of the invention disclosed herein is directed to a controlled population monitor which controls the population density of seeds delivered from a dispensing hopper to furrows formed in a field.  Seed dispensing apparatus associated with the hopper direct seeds toward the ground and includes seed-sensing apparatus for sensing the seeds actually delivered to the furrow, and to produce a signal corresponding to the number of seeds sensed.  A distance sensor is provided for producing pulses corresponding to the linear distance travelled which are modified for producing pulses corresponding to the distance traveled times the width between rows.  The pulses produced by the seed sensor and the pulses produced by the distance sensor are compared to determine whether or not the desired population density is being obtained.  Should the population density deviate from that desired, the planting apparatus is automatically adjusted to either increase or decrease the number of seeds delivered to the furrows.  This will allow constant density of seed population to be maintained regardless of changes in planter efficiencies.

Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed herein is an apparatus and method for NOx analysis in which a sample gas is introduced into a sample cell and mixed with oxygen to induce conversion of NO to NO2.  After a given time, prior to complete con-version of NO to NO2, the absorbance and the time rate of change of absorbance is measured.  The time rate of change of absorbance is indicative of the initial NO concentration in the sample gas; and the sum of the absorbance and the time rate of change of absorbance is indicative of the initial NOx concentration in the gas.  A better indication of the initial NOx concentration can be obtained from the sum of the absorbance and the square root of the time rate of change of absorbance.

Abstract: ABSTRACT OF DISCLOSURE        A flowmeter capable of accurately measuring and trans-mitting extremely low flow rates, the meter including a ver-tically-positioned flow tube having a ferromagnetic ball therein which is subjected to the force of gravity as well as to the drag force imposed by the flow of fluid to be metered.  Asso-ciated with the flow tube is a position sensor typically constituted by a light source projecting a beam across the translucent tube that is intercepted by a photosensor yielding a control signal when the beam is obscured by the ball.  The ball is also subjected to a magnetic force produced by an electromagnet energized by a current controller governed by the control signal, which force seeks to displace the ball away from the light beam.  Thus the ball acts as a force summing junction and is caused to assume a position depending on the vector resultant of the co-acting drag, gravitational and magnetic forces.  The time average current generated by the controller is a function of the flow rate and is indi-cated to afford a flow rate reading.
