Abstract: ABSTRACT The improved multi-purpose zone controlled blast furnace and method of producing hot metal, gases and slags relates to the functioning of a blast furnace as a high capacity hot metal or re-ducing gas producing unit.  Methods are known for reducing "solution loss" by injecting reducing gas Into a blast furnace, and for genera-ting reducing gas from low cost material.  However, the effectiveness of these methods Is reduced by "solution loss" and excessive costs.          The present invention overcomes these deficiencies by produc-ing a reducing gas substantially free of CO2 and H2O in a blast furnace from low cost materials and introducing such reducing gas substantially free of CO2 and H2O into the side of a blast furnace to substantially avoid "solution loss".

Abstract: ABSTRACT OF THE DISCLOSURE          To uniformly and economically disperse liquids, via sprays of droplets, on surfaces of particles a method of moving the particles involves their rotary lifting, followed by their free falling, with a spray of droplets originating from a central area of the overall motion path of the particles.  In a preferred embodiment of the method and a preferred embodiment of the blending apparatus, a hollow drum is rotated about a near horizontal axis.  Inside the drum on a common rotating shaft spaced slightly conical discs ultimately dis-perse respective sprays of droplets from a central area.  This central area is defined by particles being lifted while centrifugally held to the interior of the drum and then at a zenith locale the gravita-tional force becomes effective enough so the particles drop in an arcuate cascade path back to the interior surface of the drum to start another cycle.  The cycles are predetermined to continue until the particles acquire the selective quantity of dispersed droplets on all of their surfaces.  Then the particles leave the interior of the rotating hollow drum opposite the end of their entry into the drum.          This method and apparatus is particularly useful in treating, with liquid resin binders, and/or wax emulsions, thin wood wafers, wood flakes, wood shavings, sawdust and other particles of like respective sizes, which often are subsequently collectively formed and pressed into products, such as wood wafer boards.

Abstract: 49,236 ABSTRACT OF THE DISCLOSURE An elevator system including an elevator car, and control apparatus for controlling its speed, including a floor selector and a speed pattern generator.  The speed pattern generator provides a running speed pattern, and a slowdown speed pattern.  A smooth transfer from the run-ning speed  pattern  to  the  slowdown  speed pattern  is achieved by the generation of first and second decelera-tion  signals,  and  a  transfer  signal.  When the  floor selector issues  a  slowdown signal,  the  slowdown  speed pattern is  initiated and the first deceleration signal causes the running speed pattern to have a zero rate of change.  First and second different relationships between the running speed pattern and the slowdown speed pattern then successively cause the issuance of the second decel-eration signal and the transfer signal, with the second deceleration signal causing the running speed pattern to have a predetermined constant rate of change,  less than that of the slowdown speed pattern, such that the patterns intersect.  Pattern equality causes the issuance of the transfer signal, which initiates the substitution of the slowdown speed pattern for the running speed pattern.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention teaches a unique laser radiometer capable of accurately measuring the radiation temperature of a radiant surface and independently measur-ing the surface's emissivity.   A narrow-band radiometer is combined with a laser reflectometer to measure concur-rently radiance and emissivity of a remote, hot surface. Together, radiance and emissivity yield the true surface temperature of the remote target.  A narrow receiver bandwidth is attained by one of two methods; (a) hetero dyne detection or (b) optical filtering.  A direct measure-ment of emissivity is used to adjust the value obtained for the thermal radiation signal to substantially enhance the accuracy of the temperature measurement for a given subject  surface.   The  technique  provides  substantially high detection sensitivity over a very narrow spectral bandwidth.

Abstract: A POWER TAKE-OFF LEVER ARRANGEMENT FOR A TRACTOR            Abstract of the Disclosure A power take-off lever arrangement for a tractor is disclosed which prevents the inadvertent shifting of the PTO lever to an engaged position.  The lever arrangement includes a support plate secured to the tractor which has a pin extending outward from it which engages in a slot formed in the manually shiftable lever.  Secured to the pin is an arcuate sector which has a recess formed in its arcuate surface.  A roller, which is attached to the underside of the lever, will engage the recess when the lever is in a disengaged position and will ride on the arcuate surface when the lever is in an engaged position.  The lever arrangement further includes a spring which is attached between the lever and the support plate to urge the roller into the recess when the lever is in the disengaged position.  The spring also exerts a limited force on the lever when the lever is in the engaged position but the force is insufficient to affect either the stability of the lever in the engaged position or the movement of the lever to the disengaged position when the hydraulic pressure indirectly acting on a PTO control valve falls below a predetermined value.

Abstract: ABSTRACT          A method and apparatus for the filtration thickening of liquid-solids mixtures, such as mine tailings are disclosed.  One embodiment incorporates a support screen on one side of a filter cloth, said filter cloth having a plurality of impermeable strips arranged to form individual filtering areas separated from each other whereby filter cake forms on one side of said filter cloth when the liquid of a liquid-solids mixture flows through the filter cloth and through the support screen.          When the flow is reversed the filter cake is dislodged from the filter cloth in individual segments corresponding to the filtering areas between the strips.        Another embodiment of the invention combines an accumulator grating on the side of the filter cloth opposite the support screen, whereby when the flow is reversed the filter cake formed on the filter cloth is squeezed into a plurality of spaces and gripping surfaces on the accumulator grating and is eventually extruded through the accumulator grating.        The support screen may be partially vertically corrugated having a perimeter length substantially equal to or slightly less than the inner perimeter length of the accumulator grating such that the filter cloth remains unstressed whether pressed inwardly against the support screen or outwardly against the accumulator grating.        A plurality of said filter units are suspended in a tank for communication with a filtrate compartment spaced from the filter units whereby during the filtering process the liquid of the liquid-solids suspension flows through the filter units to the filtrate compartment.  Gravity and/or pump means provide a reverse flow from the filtrate compartment through the filter units to backwash the filter cloth and dislodge filter cake.  Dislodged filter cake is accumulated at the base of the tank for intermittent discharge therefrom.

Abstract: ABSTRACT OF THE INVENTION         A machine which is operative for handling a roll of wound sheet-like material having a loose tail end includes rollers which rotate the roll in the rewinding direction, blowers which unwind the loose tail end off the roll during rotation, and a delivery table upon which the unwound loose tail end settles for the application of glue.  A first sensor detects the unwinding of the tail end off the roll and activates a normally deactivated second sensor which turns off the rollers when the tail end reaches a predetermined location on the delivery table.  Adhesive is next applied to the stationary tail end by a glue gun which is movably mounted on a pneumatically controlled carriage assembly.  The glued tail end is thereafter rewound upon the roll, and the roll is subsequently ejected from the machine.  A third sensor detects the initial presence of the roll upon the rollers and will initiate ejection of the roll after a predetermined time period elapses, regardless of operation of the glue gun.
