Title: Preparation of a filterable co-precipitate of plutonium and uranium
IPC: G21C3/62
Filed: 1966-07-01
Abstract: 1,128,838. Nuclear fuel. UNITED STATES ATOMIC ENERGY COMMISSION. 1 July, 1966 [11 Aug., 1965], No. 29664/65. Heading G6C. In the preparation of a PnO 2 -UO 2  mixture for nuclear fuel element fabrication, a solution containing Pn and U in a mole concentration ratio of between 0.82 and 1.22 is treated with ammonium hydroxide to precipitate a mixture of uranium and plutonium hydrous oxides, and the precipitate is filtered, washed, dried, and heated in a hydrogen atmosphere at 600- 900‹ C. to reduce the mixture to oxide. The precipitate is more readily filtered and dried than precipitates in which the Pn and U molar concentrations differ. Ammonia is added to an aqueous solution of uranyl nitrate and plutonium nitrate to form a flocculent precipitate which after drying is reduced in hydrogenhelium. The product may be mixed with UO 2  or PnO 2  to adjust the Pn: U ratio, and then compacted and sintered to form fuel pellets.

Title: Improvements in or relating to means for effecting automatic steering of air and watercraft
IPC: G05D1/02
Filed: 1929-10-01
Abstract: 342,323. Steering air and water craft. DEHN, F. B., 103, Kingsway, London.-(Askania-Werke Akt.-Ges. vorm. Centralwerkstatt Dessau und C. Bamberg- Friedenau; 87, Kaiserallee, Friedenau, Berlin). Oct. 1, 1929, No. 29734. [Classes 4 and 114.] In a system for effecting automatic steering of air and water craft of the type in which rotation of a casing relative to the magnet system of a compass brings into operation a force or system of forces to actuate the rudder, hunting is prevented by the provision of means responsive to turning movements of the craft which bring into operation a force or system of forces in opposition to those first-mentioned. Figs. 1 and 2 illustrate diagrammatically one such system in which B is a compass such as described in Specification 287,871 [Class 4, Aeronautics]. Conduits m, n, the pressure of air in which is varied in accordance with relative movement of compass casing and magnet system, are connected to membrane chambers D and D<1> connected by a link 10. Movement of link 10 consequent upon variations in pressure in the chambers D, D<1> effects a rocking movement of a pivoted jet tube s through the intermediary of levers 9, 12a pivoted at 11 and 12 respectively, and of links 8, 12b. The orifice of jet tube s through which passes a constant stream of air is opposite the openings of tubes t, t<1> communicating with the opposite sides of a piston P working in a cylinder O. Movement of the jet tube s causes more air to be delivered to one side than to the other thereby causing movement of piston P which is transmitted to the rudder through rod q. A gyroscopic turn indicator, Fig. 2, having an air-driven rotor 14 is mounted for precession about an axis 16a, 16b. The pivot 11 of lever 9 is carried by an arm 15 fixed to the gimbal frame of the rotor 14 the direction of rotation being such that turning of the craft in response to alteration of the compass setting causes precession of the rotor in the sense which causes the pivot 11 to move oppositely to pivot 9a and hence reverses the position of jet tube s. The rudder is returned to its mean position after completion of a turn by means of a lever 17 connected to rod q and pivoted at 19. Movement of these levers causes movement of the jet tube s in the direction to reverse the movement of piston rod q, by means of a link 18 connected to the pivot 12 of rod 12a. According to a modification the membrane chambers D, D<1> may be replaced by a chamber containing a single membrane. The pressure in the conduits m, n, may be measured by a gauge K. Electric motors may be substituted for the pneumatic means described.

Force-feed lubricating.- An internal-combustion engine for motor-vehicles, aeroplanes, &c. is lubricated by oil under pressure supplied by the flywheel acting as a centrifugal pump. The flywheel 3 is bolted to a flange 1 of a pinion b mounted on the crank shaft a and driving a cam shaft c. Holes 4 lead from the interior spout-like periphery. of the rim 3<a> to the outer periphery, the perforated rim acting to force oil from the casing through conduits 6, 7 into a large collecting vessel 8, placed below the highest end of the conduit 6. From the vessel 8 oil is led to the crank shaft bearings. A second conduit 10 at the upper end of the casing leads oil to the bearings of the cam shaft c through a conduit 9. These bearings may, however, be lubricated from the vessel 8. Leakage is prevented by an annular disk 5, in a cavity of which rotates a flange 2 of the pinion b, the flange having helical teeth at its periphery to return the oil tending to leak. The inner edge of the disk 5 forms a channel to collect oil escaping from the rim of the flywheel.

Title: Improvements in or relating to sending devices for radio-telegraphic stations using a continuous sequence of waves generated by an arc
IPC: H03B11/08
Filed: 1920-10-22
Abstract: 152,970. La³t, P. J. Oct. 23, 1919, [Convention date]. Electric oscillations, producing; wireless telegraphy.-In an are-generator system, the sending key M is inserted directly in the antenna and an auxiliary circuit LC is connected in parallel with the arc electrodes N1, N2 and in series with the antenna, less energy being necessary to maintain the arc in operation during intervals between signals. The circuit LC has a short wave-length, for instance a harmonic of the wave emitted by the antenna, and the capacity C is of the order of the magnitude of the antenna capacity. The blow-out coils S1, S2 are excited by an independent current of constant value. The circuit LC is so adjusted that with the key open the arcoperates with a maximum arc-length. The rejector L, C1, L2 C2, and the chokes A1, A2, prevent the passage of high-frequency oscillations through the generator G. A variable resistance R is provided to increase the potential between the arc terminals when the sending key is open. According to the Specification as open to inspection under Sect. 91 (3) (a) the magnetic blowout field may be given a value varying with the value of the current supplied to the arc, by means of a device operated by the key M, for the purpose of improving the operation of the arc between signals. Increased efficiency may also be obtained by working with an are-Jength, supply voltage, inductance L or capacity C, which, while permitting greater radiation during emission on the antenna, causes extinction of the arc when the key is kept open for a prolonged period. This extinction, however, may be overcome by associating with the key slow-acting relays, through the medium of which the are-length, voltage &c. may be correspondingly varied after the key has been open a certain period. This subiect-matter does not appear in the Specification as accepted.

[Also in Groups XL (b) and XL (c)] A photo-sensitive circuit comprises two photosensitive devices 10a, 10b connected in parallel and in series with a common resistance 12 and a source of pulses 13, one of the parallel branches at least including a load 11a, 11b, the photosensitive devices being of a type which has a portion of its voltage current characteristic exhibiting a negative impedance so that when a voltage pulse occurs at 13, one of the devices will conduct heavily and prevent the other from conducting, the particular device which conducts being dependent upon the level of electromagnetic radiation in incident upon one or both the devices. In the embodiment shown the devices 10a and 10b are PNPN diodes and the loads 11a, 11b are silicon or silicon carbide electroluminescent devices. A bias 18 ensures that in the absence of light falling upon the photo diode 10a a pulse at 13 will cause 10b to pass through its negative resistance region and to conduct so that the device 11b emits light. The voltage drop across resistor 12 is such that 10a will remain highly resistive. However, if diode 10a is subjected to light or other radiation, when the pulse 13 is applied the latter diode will become conductive and the electroluminsecent device 11a will be rendered operative, the photo diode 10b and electroluminescent device 11b being rendered inoperative.
