Abstract: C-7090 ABSTRACT OF THE DISCLOSURE A diaphragm for use in the electrolysis of alkali metal chloride brines in electrolytic diaphragm cells is comprised of a support fabric impregnated with a non-fibrilic active component containing silica where the porous diaphragm has a permeability to alkali metal chloride brines of from about 100 to about 300 milliliters per minute per square meter of diaphragm at a head level difference in the cell of from about 0.1 to about 20 inches of the alkali metal chloride brines. The active component containing silica is employed in concentrations of from about 10 to about 75 milligrams per square centimeter of support fabric. Suitable silica-containing materials include sand, colloidal silica, alkali metal silicates, alkaline earth metal silicates, aluminum silicates, as well as minerals such as sepiolites, meerschaums, attapulgites, montmorillonites and bentonites. Support fabrics include, for example, felt fabrics produced from thermoplastics such as polyolefins or polyarylene sulfides, The diaphragms are physically and chemically stable, can be easily installed in an electrolytic cell, have increased operational life and are produced from inexpensive materials.

Abstract: ABSTRACT OF THE DISCLOSURE      A novel class of extractants and a method of using the extractants in the hydrometallurgical recovery of nickel and cobalt metal.  The extractants comprise a water immiscible organic solvent system containing solubilized mercaptide anions.  In an important embodiment of the invention, the mercaptide ions are generated by adding a mercaptan to a mixed water immiscible solvent comprising a basic compound such as an amine, preferably a tertiary amine, and a polar component such as an alcohol, whereby the mercaptan undergoes acid disso-ciation.    The extractants are used by being contacted with cobalt, nickel, or cobalt and nickel containing aqueous solutions. On mixing, the cobalt and/or nickel values are taken up by the organic phase as cobalt or nickel mercaptides.  These may then be stripped of cobalt and nickel by treatment with an aqueous alkaline solution and carbon monoxide.

Abstract: ABSTRACT OF THE DISCLOSURE         A chain saddle assembly is disclosed which permits a chain used as a sling to be supported at any point between its opposite ends.  The supported link is placed in a groove so that the link is lying sideways with one leg of the link above the other.  Ledges are provided which engage the two links of the chain adjacent to the link which is being supported.  The assembly thus prevents possible slipage of the chain through the assembly while providing proper support without imposing undue stress concentrations on the supported link or the links adja-cent to it.

Abstract: ABSTRACT OF THE DISCLOSURE           In an automatic phase control circuit having a predetermined lock-in range wherein the oscillating signal produced by the adjustable oscillator of the automatic phase control circuit is used in combina-tion with an input signal to derive a signal whose phase is compared to a reference signal, the phase difference between the derived signal and the reference signal being used as a phase control signal for the oscillator so as to minimize this phase difference and thus lock the phase of the derived signal to that of the reference signal, a method of adjusting the oscillator in the event that the phase relation between the oscillating signal and the input signal is outside the lock-in range.  During recurrent intervals, which vary with time base errors in the input signal, the number of cycles of the oscillating signal is counted.  The count is examined to deter-mine whether it is within a predetermined range of a predetermined count, and if outside this range, the oscillating frequency of the oscillator is adjusted in a direction to return the count to within this predetermined range.  In a preferred embodiment, this automatic phase control circuit is used to eliminate time-base errors in at least the chrominance signal of a composite color video signal.  In such an embodiment, the adjustable oscillator is used in a frequency-converter for converting the frequency of at least the chrominance signal from an input frequency to a different frequency, and it is the phase of the frequency-converted chrominance signal which is compared to the reference signal.

Abstract: ABSTRACT      Solid waste is transported to a hydrogasifying reactor and commingled with a hot synthesis gas under pressure.  The synthesis gas dries the solid waste and converts a part tc methane.  The remainder passed out of the reactor in the form of a char which is subsequently transported to a gasification reactor where it is mixed with oxygen and water vapor which converts it to a synthesis gas.  The latter synthesis gas is then transported to the hydrogasifying reactor for receiving the next charge of solid waste.

Abstract: Abstract of the Disclosure There is disclosed a discontinuously operating heat radiator con-trol system of the "co-tube type" in which one, or more, or all, of the heat radiators are thermostatically controlled with respect to the temperature in the room heated by radiators.  Each radiator is provided with a valve device comprising an inlet valve for steam and an outlet valve for condensed water.  The outlet valve is of the return blocking type and the inlet valve for steam is controlled by a movement creating means which in turn, is ar-ranged to be controlled by the thermostat.  The thermostat is placed remotely from the heat radiator in such a way that the inlet valve will, upon receipt of an indication from the thermostat of a need for heat, be periodically opened to feed steam to the heat radiator, whereafter the inlet valve will be closed.  The outlet valve for condensed water is arranged normally to be kept in closed position by means of the pressure from the steam fed to the heat radiator, but it is opened during periods when no steam is being fed to the heat radiator.

Abstract: S P E C I F I C A T I O N           SLIDE MOUNT AND METHOD AND APPARATUS FOR LOADING                   Inventor : Edwin R. Thompson ABSTRACT OF THE DISCLOSURE          An improved pre-closed slide mount is described having two sides or masks which are secured together for defining an internal pocket to retain a film transparency which is insert-ed edgewise through an opening or entranceway in one edge of the mount and defining a window for viewing the transparency in the mount.  An elevated border region formed in one mask of the mount extends transversely across the entranceway and has a sloping outer surface to provide a funnel for directing a transparency into the entranceway, and this border region has laterally sloping ends which define two spaced valleys for re-ceiving the outer edges of a longitudinally bowed film strip serving as pusher for the inserted transparency.  The outer edges of the valleys are defined by lateral transparency guides.          The border region of the other mask forms an elevated roof over the elevated border region with inverted steps over the laterally sloping end portions of the border region.  A trans-parency funneled between the elevated border region and the roof slides between the inverted steps and the elevated border region thereby moves into the entranceway.  A deflecting sur-face behind the elevated roof deflects a transparency downward-ly into the transparency pocket behind the elevated border region, and the border region then retains the transparency within the pocket.  Clamping ribs are provided adjacent the window to grip the transparency within the pocket.  A retrac-tion clearance slot may be provided adjacent one of the valleys to provide clearance for the transparency pusher as it is being retracted while lateral movement of the slide mount com-mences;  thus, the slide mount may begin moving laterally away from its loading station even though the bowed film strip pusher has not yet been fully retracted out of the entranceway.  The two masks are formed as two sides of a plastic blank hinged at the center by a thin flexible region of plastic and spaced alignment ridges.   The two sides may be folded and ultrasonically welded together to form a pre-closed slide mount.   Isolation grooves prevent flash of plastic material into the transparency pocket during the welding process.
