Title: Method for preparing uo compacts
IPC: G21C3/62
Filed: 1962-03-29
Abstract: Uranium dioxide compacts are prepared by adding 2-5% water to highly sinterable uranium dioxide, compacting at at least 3000 p.s.i. and sintering in a reducing atmosphere. After the addition of water the uranium dioxide may be converted to a free flowing powder prior to pressing and sintering by pre-pressing at at least 2500 p.s.i. and comminuting to obtain fine particles.  Sintered densities of 99% of the theoretical may be obtained by compacting at 150,000 to 200,000 p.s.i. and firing at 1200 DEG  Cl for 8 hours followed by 8 hours at 2000 DEG  C. The uranium dioxide may be prepared by precipitating uranium values from an aqueous uranyl fluoride solution at an ammonium/uranium ratio of at least 25 to 1 with thorough agitation, contacting the precipitate with steam at 400-650 DEG  C., thus forming U3O8 which is reduced to UO2 with hydrogen at 550-600 DEG  C. and re-oxidized until an oxygen/uranium ratio of 2.08-2.13 is obtained. Specification 937,330 is referred to.

Title: Improvements in or relating to the transmission and/or reproduction of sound
IPC: G10K15/10
Filed: 1926-05-13
Abstract: 276,052. Round, H. J., and West, A. G. D. May 13, 1926. Systems for transmitting music &c. - Echo or reverberation effects are added in any desired degree to a musical or like performance rendered in a non-resonant room or situation; or the echo effects may be added, electrically in the circuit of a microphone arranged for broadcasting or phonographically recording the performance. The studio may comprise a draped non-resonant main room communicating through a doorway with a resonant or echo room. The sound source is placed in the doorway and the microphone adjusted in position in the draped room to regulate the echo effect. Fig. 1 shows another arrangement in which the echo room 1 is remote from the draped studio 6. One microphone 5 in the studio transmits the sound currents directly to the line L leading to the modulator or recorder, and a second microphone 4 communicates through an amplifier 3 to a loud-speaker 2 in the echo room. A third microphone 7 in this room picks up from the loud-speaker with echo effects added by the resonance of the room 1, and superposes its currents on the line L. The degree of echo in the combined output is regulated by rheostats 8. A single microphone may replace the pair of microphones 4, 5. In this case, a valve repeater is interposed between the microphone and the line L, and the connection to the loud-speaker 2 is taken across the input side of the repeater, while the echo effects in the microphone 7 are superposed on the line L on the output side of the repeater, thus avoiding " singing " or " howling " effects. The echo room may be replaced by one or more pipes of different lengths. In a further modification shown in Fig. 3, artificial echo effects are produced by an iron bar 1<a> clamped at either or both ends and set in vibration by an electromagnetic or other device 2a traversed by currents picked up by the microphone 4. The vibrations of the bar generate currents in a second electromagnetic device 7a which are adjusted by the rheostat 8 and superposed on the line L. Resonant effects analogous to echoes may be set up by the use of long electrical circuits, by a series of closed resonant circuits, by a series of tuned mechanical reeds, or by other suitable devices. The system is applicable for adding echo effects to received broadcast music, gramophone reproductions, or primary musical performances where the surroundings are such as to make the addition of echo effects desirable. For instance a band performance in the open may be picked up by a microphone, reproduced by a loud-speaker in an echo room, picked up again by a microphone in the echo room and again reproduced, with the echo effects added, by a loud-speaker adjacent to the band and its audience.

Class 120(1) [Also in Groups XXXV and XL(b)] Apparatus for feeding opened fibrous material comprises means for conveying the material thereto, means for condensing the conveyed material, a feed trunk beneath the condenser, metering elements at the base of the trunk for delivering material at a controlled rate in the form of a partially compacted sheet, and means sensitive to the head of the material in the trunk for automatically regulating the delivery of the material to the conveying means so as to maintain the head constant. As shown, fibrous material delivered through a pneumatic duct 1 is deposited on a cage condenser 3 whence it falls into a vertical trunk 9 the walls of which diverge slightly and one wall 9a of which is adjustable to vary the crosssectional area of the trunk. Ribbed rollers 10, 11 deliver the material from the trunk in the form of a lightly compacted sheet to a lattice 12 feeding a subsequent machine; or the material may be delivered to other feed elements, to a rotary beater, or to calendering or lap-forming rollers. A motor 13 drives the various rotary members, a variable-speed gear 23 being included in the drive to rollers 10, 11. Uniformity of the delivered fibrous sheet is ensured by maintaining a constant head of material in the trunk; this is achieved by means of a photo-cell P illuminated by a light beam traversing the trunk, interruption of the beam for more than a pre-determined time disconnecting relay apparatus 5 (see Group XXXV), to cause a controller 29 to arrest or slow down the feed of material to trunk 9.
