Patent GB-1027479-A (GB)
Title: Fissio-chemical process and equipment
IPC: C01B3/04
Filed: 1964-07-29
Abstract: <PICT:1027479/C1/1> Apparatus for the production of hydrazine from liquid ammonia in which the latter, with finely divided particles of fissile material dispersed in it, flows through a nuclear reactor is described with reference to Fig. 3, with a 174 MW nuclear reactor 50 having a diameter of 8 feet and operating with ammonia under a pressure of 500 p.s.i.a. and an average temperature of 118 DEG  F., there may be circulated some 29,200 gallons/min. of ammonia through the reactor.  The residence time of the ammonia in the reactor is about 4 secs.  An inlet temperature of 90 DEG  F. is maintained by a heat exchanger 51. At a pressure of 500 p.s.i.a. the ammonia remains in liquid form while in the reactor 50. The temperature along a fission fragment path within the ammonia is of the order of 10,000 DEG  K, which causes the ammonia to decompose into hydrazine according to the reaction 2NH3 --> N2H4 + H2, the relatively low overall temperature serving to substantially instantaneosly quench the reaction.  Fluid bled off from the heat exchanger 51 at about 1300 gallons/min. contains liquid ammonia, hydrazine, fission products and particles of fissile material. Hydraulic cyclone separators 52 serve to separate out a slurry including fissile particles and the remaining fluid is passed through filter banks 53 from which the remaining fissile particles are retrieved.  The output from the filter banks is passed through a separator 54, e.g. an ion exchanger, for removing fission products and then, after the pressure has been reduced to 100 p.s.i.a. by means of a throttle expansion 56, it is applied to a distillation column 57 from which the hydrazine vapours are condensed at a rate of about 10 gallons/min. The hydrazine is passed through purification means 58 to remove vestigial traces of radioactivity and into a storage unit 59.  The ammonia from the distillation column 57 is liquefied by compressors 61 and cooled to the desired inlet temperature for the reactor by means of a suitable cooler condenser 62.  To this returned ammonia is added fissile material from the separators 52.  Nitrogen and hydrogen from the reactor in gaseous form are fed through a multi-stage compressor 66, an additional cooler 67 and a catalytic recombiner 68.  A separator 69 follows the catalytic recombiner 68 for recycling nitrogen and hydrogen and removing liquid ammonia.  In the gas recycle line, cold traps 71 are provided to liquefy the gaseous fission products, Xe at 62 DEG  F, Kr at - 81 DEG  F, and CH4 at -116 DEG  F. Liquid ammonia at 12,000 p.s.i.a. flowing from the separator 69 is passed through a throttle expansion 72 to reduce the pressure to 500 p.s.i.a. and is then directed into the input of the nuclear reactor 50.  Make-up ammonia is supplied from a source 73.

Abstract: 1395134 Bending glass sheets LIBBEYOWENS-FORD CO 27 June 1973 [23 Aug 1972] 30678/73 Heading C1M To bend a glass sheet 22 to a relatively sharp angle, a groove 24 is formed in a surface 25 of the sheet at the desired bend, an electrically conducting material 26 is applied adjacent to the groove 24 and an electric potential, through lines 32, 33, is applied across the material 26 for a time adequate to heat the sheet in the area of the groove to a temperature above the bending point of the glass, causing the sheet to bend along the groove 24. As shown, the material 26 is applied in the groove 24, but it may be applied on the opposite surface of the sheet. In another construction, the sheet has two opposed grooves, one filled with the material 36, such construction being particularly for thicker sheets. Preferably the sheet 22 is pre-heated to a temperature, 900 F. to 1150 F., below the bending temperature and fusing the material 26 to the sheet, so that the time of heating to the bending temperature, above 1200 F., is shortened and stresses are prevented. Bending of the sheet is preferably by gravity, as shown, the sheet being supported initially by its ends on an outline mould 30 with shaping rail 31, but press bending moulds may be used. A double bend may be provided with two grooves and conductive material, to give a substantially U-shape instead of a V- shape. Specification 1,365,185 is referred to.

In distillation apparatus, suitable for the desalination of water, wherein vapour evolved from distilland flowing on one surface of a porous membrane, impermeable to the liquid, diffuses through the membrane and condenses in a film of distillate flowing on the opposite surface of the porous membrane, a heat-conductive barrier is in face to face relationship, but spaced apart from the porous membrane. In the apparatus shown in Figs. 5 and 7, a series of alternate circular porous membranes 10 and heat-conductive barriers 12 are sandwiched together between a heating chamber 54 and a cooling chamber 56. Liquid-to-be-distilled, e.g. water, enters at inlet J, passes through openings 58, and flows radially outwards in film-form between each porous membrane 10 and the barrier 12 immediately above it, finally leaving the apparatus through openings 62 and outlet K. Vapour diffuses down through the porous membranes, and condenses in the spaces between each membrane and the barrier immediately below it. Distilled water flows out through openings L. Chambers 54 and 56 may form part of a heat pump containing a refrigerant. Alternatively, the chamber 54 may be heated by solar energy.

The speed of a shaft is controlled by alternately energizing a clutch coupling the shaft to a motor and a brake acting on the shaft, the speed of the shaft being measured by an A.C. tachogenerator I whose output is converted to a D.C. with ripple signal, and the clutch and brake being emergized respectively when the D.C. signal falls below or rises above pre-set reference voltages. The tachogenerator comprises a magnetic pulse generator 1 Fig. 2 (not shown) whose output is supplied to a transformer 10 which feeds a rectifier 15 and low pass filter 20, 21 to provide the D.C. signal. The transformer coupling is variable by a pedal 14 to set the speed. The output of the rectifier is biased, by potential divider 17, 18, for rapid response. The output of the filter is fed to a buffer amplifier 24 and a phase inverter 32; output from each are fed respectively to transistor pairs 40, 41 and 34, 35 supplying the coils 2, 3 of the clutch and brake respectively. The pre-set voltage levels are set by potentiometers 29, 33.

Abstract: 1,248,719. Automatic speed-control. ELMO CO. Ltd. June 25, 1970, No.30888/70. Heading G3R. An electric motor Mp employed in a motion picture projector P is operated in synchronism with a separate electric motor Mt in a tape recorder T. A normally-open reed switch 2 is operated at a rate proportional to the speed of the motor Mt, and produces firing pulses for a thyristor 1 in series with the motor Mp. A normallyclosed reed switch 3 is driven by the motor Mp and delivers a de-energizing pulse to the thyristor at a short period after each firing pulse. The phase difference between the firing and de-energizing pulses is thus adjusted to maintain synchronism between the two motors. The switch 3 may be replaced by a reed switch 3<SP>1</SP> in parallel with the thyristor. In another arrangement, the output of the thyristor is amplified before being applied to the motor Mp, Fig. 3, (not shown).
