Abstract: Abstract of the Disclosure A method for producing improved shea fat suitable for hard butter, which comprises heating raw shea fat with a lower aliphatic alcohol (e.g. ethanol, propanol or isopropanol), removing the alcohol-insoluble portion, cooling the remaining solution to separate it into two layers, the upper layer being oil-poor and the lower layer being oil-rich, and collecting the oil-rich layer.  The lower layer is then usually subjected to solvent fractionation with n-hexane, acetone or methyl ethyl ketone.  The improved shea fat can be mixed with an intermediate fraction of palm oil to give hard butter having superior tempering properties.

Abstract: ABSTRACT OF THE DISCLOSURE       A PROCESS FOR THE FUMING TREATMENT OF METALLURGICAL SLAG            A continuous process for the fuming treatment of metallurgical slag, e.g. lead and copper smelting furnace slag.          The process comprises passing the slag continuously through consecutive slag treatment zones of a fuming furnace, subjecting it in a first one of said zones to heating to fume off comparatively volatile, preferably sulphide-bound constituents thereof, subjecting it in a second one of said zones to reduction to reduce preferably oxide-bound constituents and fuming off said last-mentioned constituents in an elementary form and adjusting the temperature of the slag in said first zone such that the reduction treatment in said second zone is accomplishable substantially without further heating the slag.

Abstract: FILTER CAPACITOR CHARGING CIRCUIT          Abstract of the disclosure A circuit is disclosed for charging an input filter capacitance from a source of potential before a protective circuit, e.g., a fuse, is established between the source of potential and the capacitance.  If the charging circuit is connected between the potential source and the substantially discharged capacitance, a small charging current will flow through a current limiting resistance.  This small current will partially charge the capacitance if no faults are present.  A threshold detector circuit monitors the voltage on the capacitance and for a voltage of approximately three volts or more, in the case of a twenty-four volt potential source, activates a charging transistor.  The charging transistor is controlled by feedback circuitry to provide a larger but limited charging current to complete the charging to within approximately one volt of the potential of the source of potential.

Abstract: ABSTRACT OF THE DISCLOSURE   Radiographic apparatus is described for evaluating the absorption coefficient of a body at each of a plurality of locations distributed over a slice of a body.   A source is arranged to produce a fan-shaped beam of radiation which is directed through the body and the source is orbited around the body about an axis intersecting the slice.   Detectors are provided, and orbited in synchronism with the orbital motion of the source, each to detect the radiation emergent from the body along a plurality of paths.   A lateral scan is imposed on the source relative to the detectors, the scan being repetitive so that, during each scan, each detector receives radiation along a plurality of mutually inclined beam paths.   The beam paths thus examined are sufficient in number and distribution to allow the construction of composite measurements for a plurality of sets of composite, parallel beam paths distributed over the slice for processing to derive a representation of absorption coefficients for the slice.

Abstract: APPARATUS FOR NEUTRALIZING TONER IN A                    NO CHARGE EXCHANGE TRANSFER     Abstract of the Disclosure In a no-charge-exchange transfer, the transfer sheet leaving a no-charge-exchange transfer roller contains little or no electrical charge except for the charged toner.  Accordingly, the charged toner tends to explode off the sheet or migrate on the sheet due to like charge on the toner causing toner particles to repel each other.  A neutralizing corona is provided adjacent the  image side of the copy sheet.  This corona is positioned after the nip of the transfer roller and before the copy sheet leaves the transfer roller.  Ion  emitted from the neutralizing corona reduce the charge on the toner particles to substantially zero.  Thus, the toner particles no longer repel.  Forces of adhesion hold the particles to the paper after the sheet leaves the transfer roller and proceeds to the fusing station.

Abstract: ABSTRACT OF THE DISCLOSURE      This invention relates to a continuous flow gravitational separator having inclined membrane baffles therein which separates solid particles and also foam from a suspension liquid. A rectangular membrane assembly with a plurality of parallel inclined flexible membranes is received in a cylindrical tank, thereby defining four vertically extending arc-shaped compartments or segments between the membrane assembly and the wall of the tank.  The tank has a funnel shaped bottom solids outlet and oppositely located inflow and outflow segments are connected respectively to the liquid inlet and outlet.  The liquid flow across the inclined compartments between the membranes is distributed evenly by vertical inflow and outflow distributor plates.  The solid particles settle along the inclined membranes to a solids receiving segment, while the foam rises along the membranes to an oppositely located foam receiving segment.  Increased membrane slope adjacent the solids and foam receiving segments impedes undesirable currents between these areas and the membrane compartments.  The vertical stacking of the inclined lightweight membranes in the cylindrical tank enables a relatively inexpensive compact unit to be provided having a large capacity.

One longitudinal edge of each scroll is connected to a girth baffle disposed adjacent the side of a steam drum, and both scrolls extend through semi-circular curves of 180° in cross section.  The steam scroll is covered through the first 90° of its curve, and is provided with a longitudi-nally-elongated opening extending circumferentially the second 90° of its curve.  A perforated plate encloses the bottom of the steam scroll to form a longitudinal flow passage.  The centrifugal action imparted by the 180° cur-vature of the separator causes the water to separate from the steam-water mixture introduced between the steam and water scrolls, to flow along the inner surface of the water scroll, and to discharge downwardly through perforated, water splash diffuser plates.  The steam passes through the elongated opening in the steam scroll and through the longi-tudinal flow passage to discharge from the separator at both ends.
