Title: Method of mounting a fuel pellet in a laser-excited fusion reactor
IPC: H01S3/00
Filed: 1972-12-04
Abstract: 1386988 Thermonuclear fusion apparatus UNITED STATES ATOMIC ENERGY COMMISSION 4 Dec 1972 [23 Dec 1971] 55918/72 Heading G6P In thermonuclear fusion apparatus, a spherical target 67 (Fig. 2) is mounted, by means of a support 93, in a holder 81 forming a generally elliptical reflector and laser radiation 13 enters a chamber (Fig. 1), in which the target is positioned, via an aperture which at least partially protects the laser 11 from the reaction products produced in the chamber. In the embodiment shown, the aperture 59 is provided in a rotatable shutter 49 positioned within a neutron shield 51 so that the aperture 59 aligns with a passage 38 through the shield. Pulses of laser radiation are thus passed into the chamber to interact with the target in a "oneshot" operation. The target 67 may comprise a 1 : 1 D-T mixture or liquid hydrogen, deuterium or tritium, or lithium hydride. The target 67 and its mounting can be fabricated in a fabricator and supplied directly to the chamber. The holder 81 and support 93 may be of lithium, the target 67 being disposed at the focus of the reflector. A bottom cut-away portion 92<SP>1</SP> of the holder 81 enables some radiation to be reflected on to the support 93 to cause the latter to be vaporized. The reflector may have a copper or gold reflective coating.  The capsule 15 constituted by the target 67, support 93 and holder 81 may be held in a jig in the chamber or may be dropped by free fall into a liquid lithium vortex therein. Heat can be extracted from the chamber by a circulating fluid and used to produce power by means of a heat-engine, MHD converter, thermoelectric, or thermionic converter. Some of the electrical energy produced can be used to energize the laser.

Title: Improvements in or relating to methods and apparatus for the production of sulfates
IPC: C01D5/02
Filed: 1967-12-12
Abstract: 1,209,159. Sulphates; volatile acids. CLIMAX CHEMICAL CO. 12 Dec., 1967 [28 Feb., 1967], No. 56347/67. Heading C1A. Sulphate granules and an acid gas more volatile than sulphuric acid which is HCI, HF or H 3 PO 4  acid are produced by reacting H 2 SO 4  with the salt of said volatile acid, e.g. NaCl, KCl, CaF 2  and Ca 3 (PO 4 ) 2 , by feeding into a reaction zone the salt and a gas in such a volume and at a temperature to maintain the salt particles in a fluidized state and to maintain the reaction temperature between 700 and 1000 F., and spraying the H 2 SO 4  acid in liquid form into the salt particles. The gas can be air or acid vapours from a H 2 SO 4  acid plant converter or combustion gases or mixtures thereof. The acid spray is preferably substantially surrounded with the hot gas and/or salt feed streams in the reaction zone. In one embodiment the reactor is provided with an eccentric conical bottom 12 through which extends a sparger 14. Sparger 14 is supplied with H 2 SO 4  pumped through line 16 and salt particles entrained in a gas stream through line 18 and hot gases through line 20. As shown sparger 14 comprises an outer shell 42 and an inner shell 46 which define an annular space 56 through which the gas and entrained salt particles flow upwardly and are discharged into the reaction core with a swirling motion caused by volute inlet 44. The hot gases are directed into the reaction zone by tubes 52 and H 2 SO 4  is sprayed under pressure through nozzle 54 into the fluidized salt particles and the volatile acid gas and fine solids formed are discharged at the top of the reactor and are subsequently separated. A portion of the hot product gases can be returned to the hot gas feed and the undersized sulphate particles recycled. The sulphate granules are discharged at the bottom of the reaction zone the oversize sulphates through line 30 and the sulphate granules through line 32. In a modification the sparger has an outer annular hot gas passage and an inner annular salt passage surrounding the spray nozzle. The velocities of the gases may be increased by restricting the outlets of the passages.
