Title: Processing of nitrate solutions containing thorium and uranium
IPC: C22B60/02
Filed: 1958-11-25
Abstract: <PICT:0850887/III/1> Uranium and thorium are separately recovered from nitric acid solutions of neutron-irradiated fuel rod material by extraction from the solution with a solvent consisting of 10-60% tributyl phosphate in deca-hydronaphthalene.  The resulting solution, after scrubbing, is first treated with dilute nitric acid to remove the thorium and thereafter with water to remove the uranium as an aqueous solution.  As shown in the Figure, a three column system is preferably employed, the nitric acid solution of the fuel rod element entering the middle of the first column and passing downwardly therethrough counter current to an up flow of a tributyl phosphate/deca-hydro-naphthalene mixture which removes and entrains the uranium and thorium values to pass upward through the column counter-current to a down flow scrub solution consisting of a nitric acid/aluminium nitrate solution.  The solvent solution then passes through column 2 where it is scrubbed with .25 molar nitric acid to remove the thorium, fresh tributyl phosphate and diluent entering the bottom of the column.  The resulting tributyl phosphate solution of uranium nitrate is treated finally in column 3 with water to recover uranium nitrate solution.

Title: Improvements in or relating to Electromechanical Delay Devices
IPC: H03H9/36
Filed: 1966-08-26
Abstract: 1,159,423. Electromechanical delay lines. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 26 Aug., 1966 [26 Aug., 1965], No. 38304/66. Heading H3U. A delay line comprising input and output transducers 1 and 2, respectively, coupled to a delay medium 3, the transducers containing a material having an electromechanical conversion factor dependent upon polarization, e.g. bariumstrontium-titanate or lead-zirconate-titanate, is characterized in that in order to reduce undesired echo vibrations, the transducer material is subjected to a treatment such that the transducer exhibits polarization which gradually decreases in directions parallel to the direction 6 of the wave propagation. Thus, in transducer 1 the polarization decreases from a maximum at the electrode face 1a to nil at the electrode face 1b; similarly, in transducer 2 the polarization decreases from face 2a to face 2b. Thence, an electric pulse applied to terminals 4 causes mechanical vibrations to be excited at face 1a but none are excited at face 1b and thus undesired echo vibrations are reduced. In the treatment of the transducer material a high direct voltage is applied to terminals 4 while a high temperature slightly less than the Curie temperature of the material is maintained. This produces a uniform polarization throughout the material. Next, the transducer is exposed to a temperature gradient such that face 1b is higher than the Curie temperature, whereas the temperature at face 1a is considerably lower. This eliminates the polarization at face 1b whilst that at face la remains. A modified transducer is described with reference to Fig. 2 (not shown), in which both electrodes are formed on the same face of the transducer in the form of interleaved combs (11, 12), the polarization being a maximum on this face. In another modification the delay medium 3 is formed of the transducer material whereby separate transducers are not required. In another embodiment (Fig. 3, not shown) the delay line comprises a cylindrical member (15) formed of the transducer material, the cylindrical surface carrying interleaved comb electrodes (11, 12).

Filed: 1977-09-14
Abstract: A drive part (12) has an internal tooth system (16) into which an external tooth system (18) on a driven part (20) engages. A disc (62) which has an internal tooth system and likewise interacts with the external tooth system (18) is prestressed in the circumferential direction with respect to the drive part (12) by means of a helical spring (56) which engages on the drive part (12), in order to compensate for the backlash between the two tooth systems (16, 18). The advantage of such an arrangement is that the two coupling parts (12, 20) cannot move freely with respect to one another within their backlash and consequently as little noise as possible occurs even when the wear increases. Such a device can be used for a coupling or for a brake. <IMAGE>
