Title: Heat recovery in black liquor oxidation
Inventor: ELTON EDWARD F
IPC: D21C11/10
Filed: 1984-11-26
Granted: 1988-02-16
Abstract: ABSTRACT OF THE DISCLOSURE      The black liquor from a kraft pulping process after intermediate concentration and prior to its introduction into the conventional recovery furnace is subjected to wet oxidation with high purity oxygen. The heat of such oxidation is used to flash the liquor to dry or semi-dry solids (80-100% solids concentration) and the resulting steam is available as process steam utilized upfitream in the evaporation sequence.  The hazard of recovery boiler explosion is thus reduced or eliminated and net steam recovery is considerably improved.

Abstract: BIFOLDING SHIELD FOR AGRICULTURAL HARVESTER    ABSTRACT OF THE DISCLOSURE        A self-propelled harvester or combine is provided with a bifolding panel structure at the lateral side thereof on which a bin unloader tube is swingable from an outwardly extending unloading position to a transport position alongside the panel structure.  When the unloader tube is in its transport position, the lower part of the panel structure can be pivoted about its pivot connection with the upper part of the panel structure between closed and open positions, but the unloading tube in its transport position prevents opening the upper part of the panel structure.  When the unloader tube is raised, the upper part can be moved from its closed to its open position.         A linear air spring or actuator biasingly maintains the lower part of the panel structure in whichever of its open and closed positions it is placed, and when the upper part is swung to its open position, it is maintained in that position by the linear actuator. In an alternate embodiment of the invention, the linear actuator biasingly holds the upper part of the panel in its closed position when placed there.

Abstract: DUAL SPECTRUM FREQUENCY RESPONDING FIRE SENSOR           Abstract of the Disclosure Apparatus for sensing the ex(i)stence of a fire and providing a warning, if desired, with improved discrimination against the possibility of false alarms. Dual channel detectors are used, one detector being set to respond to incident radiation having a wavelength in the range of 0.8 to 1.1 microns while the other wavelength range is significantly displaced therefrom, being selected for wavelengths in the range from 14 to 25 microns. Reliability of true signal detection is further improved by the provision of separate flame flicker bandpass filters in the respective channels, these bandpass filters being set for different passbands.  Circuits providing ratio discrimination, threshold detectors and delay circuitry are combined with the dual spectrum detectors and disparate flicker frequency filters to achieve improved performance.  In addition, the dynamic range of instrument sensitivity is substantially increased by utilizing preamplifiers with wide gain variability controlled by automatic gain control circuits in the dual channel circuitry.

Abstract: ABSTRACT OF THE DISCLOSURE:            There  is disclosed a process for the direct  reduction  of iron-oxide-containing  materials by a gasification gas pro-duced in a gasifier by reacting carbon with oxygen and,  if desired,  with steam, upon the addition of sulfur acceptors in a fluidized bed.  The gasification gas is supplied to  a direct  reduction  shaft furnace after separation of  solid particles carried therewith.  At least part of the top  gas withdrawn  from the direct reduction shaft furnace is  com-pressed  after dust scrubbing and is recycled to the  gasi-fier.  The  sulfur acceptors are supplied as fine particles separated from the coal in cocurrent with,  and/or counter-flow to,  the fluidized-bed forming gases. The top gas from the reduction shaft furnace,  which has a concentration  of from  15 to 30 % CO2 and a temperature of from 80 to 800°C, is recycled laterally through the wall of the gasifier into the region of the fluidized bed,  which is maintained at  a temperature of at least 1,150°C.  The slag, which is in the molten  state with the temperature prevailing in the  gasi-fier,  containing ashes and sulfur compounds and collecting under the formation of a bath,  is removed via a tap in the vicinity of the bottom of the gasifier. The solid particles separated  from  the gasification gas are mixed  with  dust coal  having  a grain size of up to 3 mm and  are recycled into the bottom region of the gasifier above the surface of the slag bath.

Abstract: Abstract A coil for electrical devices has at least one axially formed winding (1).  The end surfaces of the coil are braced against one another in the axial direction by means of a preloading device containing a loop (2).  This loop (2) is intended to be pushed onto retention devices of the preloading device and supported on these retention devices so as to be free from shear.  The loops (2) are wound in several layers from elastic insulation strip impregnated with hardening synthetic resin and are hardened in a definite shape.  They are held without shear in loop retention devices (6a ... 6d, 6a' ... 6d') of the preloading device and they reliably maintain the preloading for all operational cases.         A cost effective method for manufacturing this coil includes the coil being subjected to the final preloading only after winding, fixing by means of temporary strips, impregnation with casting resin and hardening of the casting resin.  The final preloading is at least 0.5% of the clamping length of the loops (2).
