Abstract: ABSTRACT OF DISCLOSURE         In bottom blown oxygen steel making or in top and bottom blown combined oxygen steel making, a tip end of a tuyer immersed in molten steel is seriously damaged or melted away due to very high temperatures due to the vigorous combustion of carbon, manganese and so on by the oxygen blown into a furnace.         In order to prevent such damage, hydrocarbon gas has been blown through space between an outer pipe and an inner pipe of a dual pipe tuyere or tuyeres, but such hydrocarbon gas rather excessively lowers the temperature of the molten metal adjacent to the tip end of the tuyere and often blocks the opening of the tuyere.         Now, instead of blowing in hydrocarbon gas, particulate material such as limestone magnesite, dolomite and the mixture thereof are proposed to be blown into the molten metal in the decarburization steel making vessel carried by an innert gas, combustion gas, blast furnace gas, LD process gas and oxygen or a mixture of these gases.         Particulate material mentioned above, when blown into the molten metal, increases the momentum of the gas flow, enhances a shielding effect, against high radiation heat by fire point, or further forms either a kind of protective layer or deposit of refractory mineral material at the tip of the tuyere thereby effectively preventing damage of the tuyere and lengthens the service life of the refining vessel.     Addition of particulate material in continuous-ly linearly or in stepwise manner has been proved to be effective for accomplishing the above-mentioned cooling and protecting effect of the particulate material.

Abstract: Abstract:   A noncontact thickness gauge system for measuring the thickness of a material is disclosed which includes a source of penetrating radiation, a radiation detector for detecting the amount of radiation received from the radiation source where the level of received radiation is a function of the radiation absorption characteristics and thickness of the material located in the radiation path, a memory for storing the output signals of the detector and curve-defining parameters for a plurality of calibration curves which correspond to respective ranges of thickness values, and a processor for processing the various signals and curve-defining parameters to determine the thickness of the material in the radiation path.  The calibration curves are quadratic and are defined by at least three calibration points.  Measurements using the radiation thickness gauge system are done after precalibrating the gauge system to obtain a plurality of calibration curves, storing the calibration curves in the memory, providing the signals representative of the nominal thickness and the alloy compensation coefficient for the material to be measured, selecting the calibration curve corresponding to a particular thickness range, compensating the calibration curve of the selected range for drift, inserting the material to be measured into the radiation path and then processing the output signal of the detecting means with the compensated calibration curve to determine the apparent thickness of the material.

Abstract: ABSTRACT A frequency translation phase-locked loop (PLL) is provided for detecting the audio information from a television signal.  A voltage controllable oscillator (VCO) having a nominal oscillation frequency equal to the frequency difference between the intermediate frequency (IF) picture and sound carriers provides one input to a mixer and a substantially unmodulated picture carrier is supplied as the other input to the mixer.  A phase detector has as its first input the output signal from the mixer and as its second input the sound carrier. A lowpass filter coupled between the output of the phase detector and a control input to the VCO completes the PLL. The detected audio information is provided at the output of the lowpass filter.  Furthermore, the PLL can provide a defect control signal which, when applied to compensation circuitry, reduces impulse noise effects in the video information.

Abstract: Title:         Bag Mouth Closure ABSTRACT     A reclosable plastic film bag mouth closure includes bag mouth lips projecting beyond a heat-seal band closing the bag mouth and a stiffening patch bonded to the interior or exterior of a bag mouth lip between the heat-sealing band and the bag mouth end.          The patch is of a length transversely of the heat-seal band so that it and the bag lips can be folded in two return bends for holding the bag mouth closed.  The stiffening patches for the reclosable bag mouth end can be applied to a strip of sheet material for making bags at the time that the bags are formed and filled by clipping from a strip of patch-making material patch pieces having pressure-sensitive adhesive on one side.   Such patch pieces are transferred from a clipper onto the bag-making material by a revolving transfer member having a suction pick-up to pick up a patch piece and blowing means for subsequently detaching the patch piece from the transfer member and depositing it onto the strip of bag-making material.
