Abstract: ABSTRACT OF THE DISCLOSURE      A process for recovering compounds of enriched nuclear fuel from scrap materials is disclosed.  The process yields an acid solution with the nuclear fuel dissolved therein.          Except for spent filter media, the scrap materials are calcined to produce an oxidized material, which is reduced to a particulate material and leached in an acid bath that contains some recycled acid to yield an acid solution of the nuclear fuel material.  The scrap mater-ials comprised of spent filter media are mulched and con-tacted with the acid solution.  The insoluble materials are separated from the acid solution, and at least a por-tion of the acid solution is recycled to the leaching step, while the remainder of the acid solution is col-lected for subsequent treatment to recover the dissolved nuclear fuel material.  Apparatus for performing the foregoing process in also disclosed.

Abstract: UNITARY FOLDABLE DISPENSER REEL AND CONTAINER           ABSTRACT     A dispenser reel and container are integrated into a unitary foldable structure (10) which when folded into an assembled configuration, is suitable for the shipping and dispensing of a spool of wire, cable, and the like, that may be wound on a spindle or other hollow cylindrical core device.  In one embodiment, the invention is fabricated out of flat corrugated paperboard that is easily cut to appropriate dimensions and provided with fold creases (e.g. 102, 104, 106, 108) or score lines that make it readily foldable around the packaged spool of cable or the like.  In said one embodiment, the cut corrugated paperboard comprises two interconnected substantially recantagular portions (12, 14) and two interconnected substantially circular portions (16, 18), each circular portion having partially cut fold-out wing portions (48, 50, 52, 54).  The substantially rectangular portions, which form two of the walls of the container, have margin portions (e.g. 22, 24, 30, 32) along their perimeters which form the remaining four walls of the container when they are folded into place.  A first circular portion (18) is integral to a selected margin portion (30), while the second circular portion (16) is connected to the first by a bridge (20) which also functions as a stand for the assembled dispensing reel.  The fold-out wing portions are folded into the center of the reel to form a spindle upon which a spool of dispensable product such as cable is to be mounted.          In one embodiment, the fold out wing portions have interlockable tabs (e.g. 60, 64, 68, 72) that provide means for locking the wing portions together into a secure spindle configuration.

Abstract: ABSTRACT OF THE DISCLOSURE   An apparatus and method for precise separation of synchronizing information from a color television signal is described. Synchronizing signals are separated from the input video and used in a sample-and-hold circuit as the sampling pulses. The input video is sampled during the duration of the sync pulse. The sample is inverted and fed to a summing point where it is summed with a delayed version of the input video. A null is produced at the summing point during the duration of the input sync pulse. Since the input video to summing point has been delayed, the clamp null at the summing point begins during the front porch of the horizontal line interval allowing the leading edge of sync to be picked off very accurately by a sync separating comparator.

Abstract: CHROMIC ACID PRODUCTION PROCESS USING A THREE-COMPARTMENT CELL                        ABSTRACT OF THE DISCLOSURE   Chromic acid production is now simplified in a process using the concentrated dichromate typically available at an intermediate stage when chromic acid is produced from chrome ore. In the process, the dichromate is treated in a three-compartment cell as, for example, after removal of the sulfate or carbonate salt evolved in the overall production process. The dichromate feed enters the center compartment of the three-compartment cell and then flows through a porous diaphragm to the anode compartment of the cell and is electrolyzed at elevated current density. Depleted feed solution maybe withdrawn from the center compartment and recirculated for reuse. Concentrated, water-white alkali product is produced in the cathode compartment. The anolyte from the cell, rich in chromic acid, can be concentrated, cooled, and the chromic acid recovered. Liquid removed from chromic acid recovery can be recirculated for subsequent electrolysis, as by combination with the feed. Both alkali product and anolyte chromic acid can be produced at enhanced current efficiency.

Abstract: SOLID FUEL HEATER WITH IMPROVED PRIMARY/SECONDARY AIR CONTROL SYSTEM ABSTRACT OF THE DISCLOSURE A solid fuel heater comprises a plurality of horizontal tubes defining between a vertical partition and an opposed vertical wall of the heater, a tubular grate with given ones of the tubes connected to a primary air source manifold header while others are connected to a secondary air source manifold header for preheating the air. The ends of the tubes opposite the connection to the headers open, respectively, to the upper side of the tubular grate for delivery of primary air and to the lower side for delivery of secondary air. The vertical partition wall forms a hot air passage for a downdraft operation leading to the stack. Preferably, a secondary grate underlies the tublar grate. By operating in a downdraft manner, only the lower ends of the solid fuel are burned, permitting low stack temperatures and long burning operation of the heater whether wood or coal fired.
