Title: Method for direct separation and recovery of plutonium from irradiated nuclear fuel
IPC: C01G56/00
Filed: 1964-06-03
Abstract: 1,060,965. Plutonium separation. JAPAN ATOMIC ENERGY RESEARCH INSTITUTE. June 3, 1964 [Feb. 10, 1964], No. 22908/64. Heading G6R. Plutonium is separated from irradiated nuclear fuel by pulverizing the fuel by repeated oxidation and reduction, mixing the fuel in the oxidized state with a high molecular weight alkyl tertiary amine nitrate, separating the resultant plutonium-amine complex from the residue, and then precipitating the plutonium as plutonium oxalate with an oxalic acid solution. Irradiated uranium fuel, in metal, oxide, or carbide form, is alternately heated in oxygen to form U 3 O 8  and reduced in hydrogen to UO 2 . The powdered product in the U 3 O 8  form is ball milled with trioctylamine nitrate, prepared by shaking the amine with dilute nitric acid and separating the amine phase. The milled mixture is leached with kerosene containing octyl alcohol and the liquid separated from the residue containing uranium and fission products. An aqueous solution of oxalic acid is mixed with the kerosene solution to precipitate plutonium oxalate. In an alternative process the pulverized U 3 O 8  is mixed with the amine nitrate diluted with kerosene. Other suitable amines are trilaurylamine and cyclohexyldilaurylamine. Reference has been directed by the Comptroller to Specification 907,830.

Filed: 1972-05-16
Abstract: 1390094 Rolling mills BRITISH STEEL CORP 15 May 1973 [16 May 1972] 22946/72 Heading B8M A rolling mill stand includes a pair of rolls 7 through which stock is passed, one of the rolls being supported such that it can rock about a central axis perpendicular to the plane containing the roll axes. The upper roll (Fig. 3) is supported in a frame 15 which is connected to an arm 16 for pivotal movement about a pin 18. Bearing surfaces 24 and 25 allow such movement. The two rolls are movable towards and away from each other by pairs of arms 21, 22 and 12, 13 which support the rolls. The arms are pivoted about axes 9 and 10 (Fig. 2) and are moved in unison by rams 11. Links 30 and 34 are coupled to the arms and to a limit switch assembly 37 and screw assembly 38 for limiting the movement of the arms and maintaining a desired pass line. The mill is suitable for rolling tapered leaf springs 39 which are drawn through the rolls. Tapered formers 40 on each side of such a spring determine the degree of taper produced, and determine the position of the upper roll about its pivot pin. The rolls are suitably freely rotatable.

Filed: 1974-05-23
Abstract: 1467038 Automatic exchange systems WESTERN ELECTRIC CO Inc 23 May 1974 [29 May 1973] 23039/74 Heading H4K A strowger switch is arranged to apply an identifying tone to the sleeve lead during the period in which it is responding to a digit stream, i.e. "B" relay operated, and a scanner is arranged to scan the sleeve leads and to give an error indication if an identifying tone is present on a sleeve lead for greater than a predetermined time. The scanner may be situated in the same or a different exchange from the monitored switch. A group of six tones representing the office number, stage number, frame tens digit, frame units digit, switch location (switch tens) and shelf number (switch units) are supplied to each switch's sleeve lead by a distribution arrangement of tone transformer winding (Fig. 2, not shown) connected between earth and the "B" relay contact which is closed to supply holding potential to the sleeve lead whilst the switch is stepped by the "A" relay responding to a digit train. In a first embodiment Fig. 1, these tones are detected by a scanner 28 positioned at the incoming side of the tandem 3rd selector and the local 4th selector. In operation the scanner stops on any sleeve exhibiting ground plus a tone signal and the detected tone is supplied to the input of 56 tone detectors (Fig. 5, not shown) to cause a ten second timer to be energized. Markings representing the 6 part tone are then extended to a microcomputer if the tone is present for ten seconds and information identifying the faulty switch is printed out. The scanner remains connected to the sleeve lead until a series of tones have been received representing the different stages of the path selection through the various selectors, where the scanner is situated at an originating exchange such as an ESS the tones are coupled back to the ring and tip conductors of the incoming trunks 5<SP>1</SP> at the remote exchange by a bridge 41 (Fig. 5) and are then removed by a similar bridge 41 in the dial pulse transmitter of the originating exchange 42. If the originating exchange is of the step-bystep type 50, a scanner 27<SP>11</SP> and microcomputer 30<SP>11</SP> (Fig. 5) may be provided to monitor both the 1st and 2nd selectors of the originating exchange and the final selectors of a remote step-by-step exchange. Statistical metering.-Instead of tone information only being supplied to the minicomputer if the timer times out, it can be arranged for the detection of even tone to be registered by the computer. Data on the usage of the selectors can then be collected.

Title: Method of operaing a furnace with prereduced pellets of ore
IPC: C21B13/00
Filed: 1971-04-19
Abstract: 1333846 Smelting iron ore NIPPON KOKAN KK 19 April 1971 [26 Feb 1970] 23465/71 Heading C7D A process for smelting pre-reduced pelleted iron ore comprises blowing a non-oxidizing gas through the smelter charge, the temperature of the gas being at least as high as that of the charge at the points where the gas is blown into the furnace. The blowing of the gas increases the available heat capacity of the furnace and thus thermally stabilzes the furnace when operating with lowered coke/hot metal ratios. The non-oxidizing gas may be nitrogen, carbon monoxide, mixtures containing them, or waste gases from combustion, and is blown into positions above the tuyeres at temperatures above 800‹C. preferably between 850 and 1200‹C. Apart from preventing undesirable cooling in the upper portions of blast or shaft furnaces, the invention is also applicable to cupola or electric smelting furnaces. The pellets may be combined with scrap metal.

[Class 59] A device for feeding powder to water &c. comprises a receiver for the material and a discharging member which is actuated rectilinearly in a succession of steps in the same direction to push the material from the receiver. As shown, a plunger 18, Fig. 5, is reciprocated across a surface 10 which receives material from a hopper 2 provided with a rotary cutting member 94 attached to arms on a rotary shaft 93. The plunger is connected to an arm 22 on a shaft 23 which is rocked by an arm 74 through a connecting rod 75 attached to an arm 73 on a spindle 40. A flanged drum 41 is fixed on the spindle 40, Fig. 4, and is driven by pawls 80 and 43 mounted on an arm 84 and engaging the outer and inner surfaces of the flange respectively. The pawl 43 is provided with a pin 88 which enters a recess 82 in the pawl 80 whereby the pawls are moved simultaneously. A roller 69 is mounted on the pawl 80 and engages the edge of disc 46 having a stepped surface 65 and rotatably adjustable by a worm engaging a quadrant. The arm 84 is connected to a motor driven disc 37 by a connecting rod 47 and is provided with a brake 70.

Title: Process of and apparatus for obtaining coarse crystals of ammonium salts formed in an acid saturator
IPC: C01C1/12
Filed: 1931-08-21
Abstract: <PICT:0370793/III/1> A process for obtaining relatively coarse crystals of ammonium salts, for example, ammonium sulphate, produced in an acid saturator comprises leading the saline liquor therefrom to a collecting vessel, therein separating the fine crystals from the coarse crystals by means of a suspensory current, and returning the fine crystals to the saturator.  Referring to the drawing, the crystal magma produced in saturator a is conveyed continuously or intermittently by ejector c to vessel e, into which a current of air is introduced by pipes j.  The fine crystals in suspension return to the saturator via pipe g, whilst the coarse crystals sink to the bottom of the vessel e, and are transferred at intervals to centrifuge i, the mother liquor separated being returned to the saturator.  A basic neutralizing agent may be admitted through pipe k prior to or during removal of the crystals.  The vessel e is cooled by expansion of the injected air, but, if desired, additional cooling means may be employed.
