Filed: 1976-03-29
Abstract: 1528415 Actinide separation or recovery UNITED STATES DEPARTMENT OF ENERGY 29 March 1976 [15 May 1975] 12486/76 Heading C1A [Also in Division G6] In a process for recovering actinide values from an aqueous feed solution by extraction with an organic solvent having a greater density than the aqueous feed solution and containing tributyl phosphate (TBP), followed by stripping at least some of the actinide values back into an aqueous solution, ferric ions are added to the aqueous feed solution in order to remove degradation products of TBP, for example dibutyl phosphate and monobutyl phosphate, by forming a precipitate therewith during the first stage of the process, which precipitate is withdrawn from the interface between the two phases. Extraction may be effected with a solution of TBP in carbon tetrachloride or trichlorobenzene using packed or pulsed columns or mixer-settler devices. The process may be used for the treatment of nitric acid solutions of waste material or spent nuclear fuel for the recovery of plutonium or the separation of plutonium and uranium. Plutonium may be separated from the organic phase from the first stage by stripping with an aqueous solution containing hydroxylamine nitrate, hydrazine, or ferrous sulphamate as a reducing agent.

Abstract: 904,787. Substation equipment. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 10, 1961 [April 14, 1960], No. 13459/60. Class 40 (4). A tuned reed device in a substation comprises digit-transmitting reeds tuned to different voice frequencies and a receiving reed tuned to a particular voice frequency, the transmitting reeds being formed partly or wholly of magnetic material and being positioned in a magnetic circuit so that when they are vibrated by digit keys associated therewith they cause pulses of alternating current to be sent to line due to the change of flux through an inductive winding linking the line and the magnetic circuit, and the receiving reed, also partially or wholly of magnetic material, being vibrated in response to the flux change in the magnetic circuit when ringing current is applied to the line so as to induce an alternating voltage in an output winding associated therewith. A non-magnetic base member 11 (Fig. 1), supports a first permanent magnet 14 having soft iron polepieces 15, 16. A receiving 18 and transmitting reeds 17 all tuned to different voice frequencies and made of magnetic material are attached to polepieces 15 in such a way that they overlie and extend beyond, but do not touch, polepiece 16. The reeds 17 are caused to vibrate by the depression of digit keys 19, the reeds again being vibrated when the keys restore to normal under the action of springs 22. Thus two alternating voltage pulses are sent to line each time a key is operated due to the change of flux in the magnetic circuit, when the reeds vibrate, being detected by a coil I connected in a circuit across the line wires. A second permanent magnet 24 having polepieces 25, 26 and carrying a calling current output winding II is supported below the free end of reed 18 so that when the latter is caused to vibrate by the appearance of ringing current in coil I, a corresponding alternating voltage will appear across coil II. The tuned reed device is indicated by TRD in Fig. 2, coils I and II corresponding to those mentioned above. In the normal condition any noise voltage present on the line wires (connected to B, A) is detected by transformer TXB, rectifiers MR1, MR2 and applied to the base of a transistor TB to maintain this non-conducting. When ringing current of the appropriate frequency, a different frequency being used for each station on a party-line, is applied for a time depending on the time constant of R2, C4 then the output of coil II, after rectification by MR3, MR4, will be sufficient to cause TB to conduct and consequently the blocking oscillator TXA, TA will operate to produce an audible note in the sounder TS.

Title: Antiknock agents
IPC: C10L1/10
Filed: 1944-07-13
Abstract: An anti-knock agent for addition to motor fuels comprises a mixture of iron pentacarbonyl and a tetra-alkyl lead whose proportions on a chart having grams of lead per gallon of fuel on the horizontal scale and grams of iron per gallon on the vertical scale lie within an area bounded by straight lines through the origin and the points 3.18 grams of lead, 1.68 grams of iron and 1.06 grams of lead, 2.52 grams of iron, and a horizontal line corresponding to 1.68 grams of iron. Preferably, a mixture of three parts iron pentacarbonyl and one part tetraethyl lead is used.  The range of lead alkyls mentioned as suitable is from dimethyl diethyl lead to tetra-n-butyl lead, but tetramethyl lead and trimethyl ethyl lead can also be used.  Alkyl halides may also be added.  The agents specified lie outside the ranges where the anti-knock effects of each component are mutually inhibitive, and at the same time lower the cost of the mixture by lowering the amount of the dearer lead alkyls necessary to produce a required anti-knock value.  A chart showing a series of curves of progressive anti-knock values for varying porportions of tetraethyl lead and iron pentacarbonyl is given.  Specification 252,018, [Class 91], is referred to.
