Title: Removal of organic and inorganic iodine from a gaseous atmosphere
IPC: B01D53/68
Filed: 1972-08-03
Abstract: 1361366 Gas separation; iodine oxyacids UNITED STATES ATOMIC ENERGY COMMISSION 3 Aug 1972 [26 Aug 1971] 36251/72 Heading C1A [Also in Division G6] Iodine or a compound thereof, e.g. methyl iodide, is removed from a gas by contacting the gas with a refluxing aqueous solution which is at least 15À3 M in nitric acid and is preferably at a temperature of 90-125 C. The method may be used for the removal of radio-active iodine from fission product-containing gas released from a nuclear reactor or from a spent fuel reprocessing plant. The acid may be contained in a flask surmounted by a reflux zone and two condensers, the condenser temperature being adjusted so that the gases NO and NO 2  are removed. Any residual iodine may be separated by a silver-containing zeolite. The iodine is converted to iodic acid which may be recovered from the nitric acid solution as HIO 3 , HI 3 O 8 , or I 2 O 5 ; alternatively the solution may be neutralized with alkali and the concentrated solution treated with nitrite to release elemental iodine.

Title: Improvements in or relating to the continuous heat treatment of yarn at low or zero tension
Inventor: CRABBE PETER JOHN
IPC: D01D10/04
Filed: 1960-10-22
Abstract: In a process for the continuous heat treatment of yarns at low or zero tension, contractible yarn is forwarded to fall only under its own weight into coils or loops within a straight upright tube, the space within which is heated, in such manner that the lower coils or loops provide a slowly yielding support for the coils or loops above them, and the yarn from the successive lowest coils or loops is withdrawn in a linear path at an angle to the axis of the tube.  The contractible yarn may be a continuous filament yarn of a synthetic thermoplastic material, having an p  inherent propensity to crimp when heated in a relaxed condition, or a yarn having too high a shrinkability, e.g. of nylon, the space within the tube then being heated to a suitable setting temperature to induce shrinkage of the yarn.  Yarn may be forwarded by means of a pneumatic device or by allowing it to piddle freely from a roller positioned above the tube. The lower coils or loops of yarn may themselves be yieldingly supported by means attached to the lower end of the tube, and a tension may be imparted to the yarn on withdrawal.  The level of yarn within the tube may be determined and controlled either by correlation and control of the rates of forwarding and withdrawal, or by control of the tension in the yarn on withdrawal, whilst keeping the input tension and the forwarding and withdrawal speeds constant. The yarn may be subsequently wound up on a bobbin, or coiled within a container or, whilst still in compacted form, may be wrapped with a tape immediately after withdrawal and the sowrapped yarn wound-up on a bobbin.  Suitable apparatus comprises the yarn-forwarding means previously described, a straight upright tube which can be heated to the desired treatment temperature (e.g. by passing an electric current through the tube, or through coils wound around the tube, or by circulation of hot fluids), a device at the lower end of the tube adapted to constrict the opening at the lower end by an amount sufficient to enable coils or loops of the yarn to be formed above it within the tube and to offer yielding support to the weight only of said coils and loops (e.g. an inwardlydirected lip of knitted fabric, especially cotton stockinette), and means for withdrawing yarn from the lower end of the tube through said device and at an angle to the axis of the tube and for winding-up the yarn.  Between the lower end of the tube and the yarn withdrawal means may be interposed means for imparting tension to the yarn, especially finely-divided members through which the yarn is constrained to pass, making contact with some of the members on all its sides.  The pile fibres of two opposing pile-surfaced materials, particularly of nylon velvet, may be used for this purpose.  Yarns of nylon, polyesters, polyacrylonitrile and isotactic polypropylene may be treated by the above process.  Specification 797,051 is referred to.

Dec. 4, 1929, Nos. 37230 and 39904. [Class 38 (iv).] A Ward-Leonard ship propulsion system with generators 1, 2 and motors 3, 4 in series is arranged so that upon one machine becoming inoperative it is withdrawn from service by de-energizing its field 6, 7, 8 or 9, and adjustments are made to the strengths of the other fields or the voltage is regulated by speed regulation of the prime-movers. The inoperative state of a machine is ascertained by relays 35, 38 responsive to unbalance of voltage across each pair of machines. Assuming generator 1 becomes inoperative, contacts 36 of relay 35 open and consequently field contactor 19 opens. Auxiliary contacts 21 break a short-circuit across resistance 18 thereby weakening the motor fields. If a motor becomes inoperative, its field is opened and the generator fields are weakened. If both a generator and motor become inoperative, the resistance 18 remains short-circuited and a shortcircuit is placed across the part 17 of resistances 16, 17.

Abstract: 523,254. Impulse transmitters. SMITH, J. A. Dec. 28, 1938, No. 37673. Convention date, Dec. 29, 1937. [Class 40 (iv)] A device for imparting to the finger dial 12 of an impulse transmitter 10 the successive movements normally effected by hand when calling a subscriber, more particularly for use in making an alarm call, comprises a shaft 14 arranged coaxially with the dial and rotated continuously throughout the operation, a coupling member 50 carried by the shaft 14 being moved into and out of engagement with the dial under the control of a cam disc 38 driven by the shaft 14 through reduction gearing 30, 32. The shaft 14 is driven by a spring motor, for example, through a belt 18 but is normally held by a brake shoe 24 which can be released by the magnet 82. A lever 44 carrying the member 50 is pivoted at the end of the shaft 14 and is controlled by a spring 56 and a magnet 46. To start the apparatus contact 78 is closed, operating 82 and releasing the shaft 14. After a small angular movement of the shaft 34, the cam disc 40 closes the contacts 74 so that 82 remains operative independently of 78 until 34 has completed a revolution. The magnet 46 is energized whenever contacts 62 and 66 are closed together. The cam disc 38 determines, by the spacing of the projections 70, the digits to be dialled and cam disc 28 only allows the magnet 46 and lever 44 to be operated when the member 50 is opposite a finger hole, the projections 64 on disc 28 defining their positions. The dial is released to send impulses when a projection 52 on the lever 44 engages a cam 53 which corresponds to the usual finger stop. When the disc 38 has completed a revolution, during which a complete number has been dialled, the recess 72 allows contacts 68 to close and relay 88 operates to prevent further operation of 46. The recess 76 in disc 40 at the same time causes contacts 74 to open and releases 82 to stop the motor. Relay 88 is released by opening switch 80. The cam disc 38 determining the digits dialled may be composed of a number of superposed discs each having a single projection and angularly adjustable to determine the number to be transmitted.
