Title: Radial Split Flow Breeder Reactor
IPC: G21C1/07
Filed: 1968-04-16
Abstract: 1,158,376. Reactors. UNITED STATES ATOMIC ENERGY COMMISSION. 16 April, 1968 [26 May, 1967], No. 17923/68. Heading G6C. In a fast, sodium cooled, breeder reactor, a settled bed of fuel particles is supported in the core within mesh or sintered containers through which the coolant also flows. The fuel slurry, consisting of fuel particles, in coolant liquid, is introduced into each fuel module through pipe 24, and the particles are deposited in the conical annular space 48 between the mesh screens 50, 52. Coolant flows upwards through the inlet 60 and flows radially through the screens 50, 52. The coolant may be lithium or potassium. During operation, some fuel particles expand from annulus 48 into the separator 32 and downwardly through the inlet pipe 24. Intermittent fluidization is effected, during operation, by injecting carrier liquid or coolant through the manifold 28 and pipe 72 to produce uniform fuel burn-up and plutonium production. The fuel particles may be uranium and/or plutonium in the form of ceramics or dioxides.

An inverter of the type in which a turn-off circuit turns off any conducting controlled rectifiers by connecting a charged capacitor across the D.C. lines so as briefly to reverse the polarity of the input has additional diodes connected between the reverse current diodes and the supply, and the turn off circuit is connected between the additional diodes and the reverse current diodes. In Fig. 1 a bridge inverter comprising controlled rectifiers 11, 12, 21, 22 and having reverse diodes 13, 14, 23, 24 supplies a motor 10 from the D.C. source. Two turn-off circuits 4, 5 are provided, comprising a capacitor and four controlled rectifiers, and each turns off the controlled rectifiers connected to one pole of the D.C. supply. Each turn-off circuit is connected between the D.C. pole to which the associated controlled rectifiers are connected, and the junction of the additional diodes and reverse current diodes associated with the other controlled rectifier. In another embodiment (Fig. 4, not shown) a single turn-off circuit is used. The inverter may be three-phase (Fig. 2, not shown). If only one controlled rectifier is fired then circulating current may flow in the load without drawing power from the supply. To equalize loading two rectifiers are used alternately, for each direction of circulating current (Fig. 3, not shown).

Title: Process for the production of colloidal dispersions
IPC: B01J13/00
Filed: 1930-06-19
Abstract: Colloidal dispersions of solid or liquid substances are prepared with the use, as the dispersion medium, of a dispersion of a solvent for the substance to be dispersed.  For example, a solid substance may be dissolved in a solvent, and the solution mixed with a dispersion of a solvent; or the solid may be treated directly with a dispersion of a solvent, preferably with the addition of an emulsifying agent; or the solid may be treated with an insufficient amount of solvent to dissolve it, and then distributed in a dispersion of a solvent.  The solvents may be recovered from the dispersions by heating.  According to the examples (1) rubber is dissolved in benzene, and the solution is dispersed in an aqueous dispersion of benzene, preferably containing an oleate or other emulsifying agent; (2) olive oil is introduced into an aqueous dispersion of benzene containing an emulsifying agent.  The preparation of dispersions in alcohol is referred to.
