Title: Fuel element for high temperature nuclear reactor
IPC: G21C3/62
Filed: 1970-04-28
Abstract: 1,240,250. Fuel elements. AUSTRALIAN ATOMIC ENERGY COMMISSION. 28 April, 1970 [5 May, 1969], No. 20454/70. Heading G6C. A spherical fuel element comprises a core 1 in the form of a dispersion in a fine grained BeO matrix of a finely divided solid solution of at least two of UO 2 , ThO 2  and PuO 2 , a dense outer shell 3 of fine grained BeO, a buffer zone 2 of porous BeO between the core and the shell, a dense outer coating 5 of Al 2 O 3  on the shell, and a thin layer 4 of chrysoberyl as a bond between the outer coating and the shell. In producing such a fuel element, the solid solution-BeO dispersion-is formed into a sphere at a low pressure in a steel die and a slurry of BeO powder in a suitable vehicle, e.g. saturated camphor-alcohol solution, is sprayed on to the resultant core 1. Two hemispherical BeO shells are formed in a steel die at a low pressure and assembled over the sprayed core 1, 2, and the whole is then isostetically pressed at high pressure. A thin layer 4 of BeO + Al 2 O 3  powder in a suitable vehicle, e.g. water, may be sprayed as a slurry on to the shell surface to form an undercoat (which during sintering becomes chrysoberyl), and then a thicker layer 5 of sinterable Al 2 O 3  is sprayed as a slurry, preferably an aqueous slurry, on to the undercoat surface. The undercoat is optional since the chrysoberyl layer will result in any event at the interface between the shell 3 and the layer 5. Finally, the element is pressed isostatically at high pressure, dried out slowly, and sintered at a high temperature in a dry gas, preferably air.
Patent GB-635298-A (GB)
Title: Improvements in or relating to the separation of gaseous mixtures
IPC: B01D53/26
Filed: 1947-07-29
Abstract: Separation of a constituent of a gaseous mixture is effected by passing the mixture and a condensible sweep vapour on opposite sides of a porous diaphragm in a diffusion zone, the constituent passing through the diaphragm and being swept away by the sweep vapour and the temperature on the sweep vapour side of the diaphragm being sufficiently high to prevent condensation of gas or vapour therein and that on the gas side of the diaphragm being sufficiently low to condense the sweep vapour diffusing through the diaphragm.  The process is applicable to the removal of hydrogen from coke oven gas, refining still gas or oil-cracking still gas.  The gaseous mixture is passed through heater 20 and then through the <PICT:0635298/III/1> annular chamber 26, one wall of which comprises a porous diffusion diaphragm 30.  The sweep medium, e.g. steam, is passed through superheater 42 and then through the annular sweeping chamber 46 heated, if desired, by heating coil 50.  Chamber 26 is cooled by jacket 64 to condense all or part of the steam which diffuses through the diaphragm 30.  Steam together with gas which diffuses through the diaphragm 30 is led off from chamber 46 to condenser 56 and receiver 58 from which the condensed steam is withdrawn by outlet 62.  Gas together with condensed steam is led off from chamber 26 to receiver 68 from which water is withdrawn by line 74.  Gases leaving receivers 58 and 68 may be recycled to the diffusion apparatus.  Valves 80 and 82 serve to control the pressures in chambers 26 and 46.  The steam and gas may be passed concurrently or countercurrently through chambers 46 and 26.

Abstract: 927,456. Radio signalling. BRITISH TELECOMMUNICATIONS RESEARCH Ltd., and AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. June 19, 1959 [June 26, 1958], No. 20595/58. Addition to 850,698. Class 40 (5). In a telephone exchange serving a group of subscribers over a common radio link, means are provided to ensure the transmission of the complete selected ringing code irrespective of the times at which the radio link is established or the selected subscriber answers the call. The operation is as described in the parent Specification until relay D is released and relay DQ operates, i.e. when the initial signal transmitted by the exchange in the form of selected tones is acknowledged by a signal from the called subscriber station signifying that the radio link is established. Extra contacts are provided for relays D, DQ and a ring start-stop circuit is included in the final selector. The energizing circuit of relay PQ is completed at the beginning and end of each ringing cycle, thus at the start of the cycle succeeding the reception of the acknowledging signal, relay RS is energized through contacts PQ1, D3 and is held by contact RS1. Relay RG is energized from the negative wire of the final selector through contact RS2 to cause transmission of the ringing code. When the subscriber answers, relay D operates and transfers contact D3 to complete the energizing circuit of RS through the normal position of contact PQ1. Relay RS is released at the following end of a ringing cycle when relay PQ is again operated and the positive and negative wires of the final selector are earthed through contacts DG3, D4 and RS2, DQ2, D2, respectively. The ringing circuit responds to these earths and ringing ceases. Control signals are transmitted by a subscriber to the exchange using a tone frequency which lies outside the frequency-band used for speech.

Abstract: 760,531. Thermally-actuated valves. REEKIE, R. B. July 19, 1954, No. 20938/54. Class 135. [Also in Group XIII] A thermostatically-controlled steam trap or valve comprises a temperature-responsive bronze corrugated tube M filled with a non- volatile, non-corrosive liquid, e.g. turpentine, naphtha, mineral oil, and enclosed in a metal protective casing N having holes N<SP>1</SP> through which steam entering the outer casing E may pass. The tube M at its lower end is formed integral with or secured to a socket member L housing a loose ball valve K engageable with a removable seat J, and at its upper end is connected by a cap Ll to a screw - threaded adjustment spindle A. When the valve is cold and no steam is passing the ball K is unseated. On steam passing through the valve, the tube M expands to move the ball K towards its seat and when the heat is sufficient causes the valve to close, whence condensate collects beneath the ball, the condensate being expelled on the reopening of the valve. The ball K may be of stainless steel and the seat J of stainless steel or nickel alloy. When high-pressure steam is being used a baffle-plate having a ring of tapped holes supporting a like number of tubes may be fitted so that the steam passes through the tubes before coming into contact with the casing N and the tube M. A mica joint may be fitted between the valve body I and the outer casing E to protect the tube M against excessive heat when superheated steam is being used.
