Filed: 1958-10-20
Abstract: 871,314. Processing nuclear fuel; nuclear reactors. UNITED STATES ATOMIC ENERGY COMMISSION. Oct. 20, 1958 [Dec. 5, 1957], No. 33369/58. Class 39(4). Fission products are removed from liquid metal nuclear fuel, in which the fissile material consists predominantly of plutonium, by contacting the fuel with an immissible liquid metal which has an affinity for fission products. Suitable metals are lanthanum, silver, the alkaline earth metals, and the alkali metals. As shown in Fig. 3, the liquid fuel is cleansed within the critical part of a reactor, in which plutonium is contained in a cylindrical vessel 15. Liquid lathanum passes upwardly through holes 14, scavenging fission products from the plutonium and removing heat. Lathanum collects in upper vessel 12 and flows through pipes 19, 21 to tank 20 where it is cooled and separates into two layers, the lathanum layer returning through pipe 23 to the lower vessel 11 and the plutonium layer returning through pipes 24, 17 to the vessel 15. Some lanthanum is withdrawn periodically for removal of fission products. A system for decontaminating liquid fuel outside the reactor is described with reference to Fig. 2, not shown. The fuel may be a eutectic alloy of plutonium and iron, in which case iron is added also to the scavenging metal.

Title: Vacuum sheet-feeding device
IPC: B65H3/12
Filed: 1965-08-09
Abstract: 1,079,596. Feeding sheets. N. E. DOVEY. Aug. 9, 1965, No. 34075/65. Heading B6B. A device for separating sheets 10 one by one from the bottom of a pile and moving them horizontally into the bite of feed rollers, comprises a horizontally-reciprocated member 32 having mounted therein a vertically-movable relatively-large knurled surface 80 surrounded by an air chamber formed, e.g. by the lip 176 of a diaphragm 174, the arrangement being such that during movement of the member in the feeding direction, the surface 80 is moved upwardly and vacuum is applied to the chamber so that the bottom sheet is gripped and fed forward, and during the reverse movement the surface 80 is lowered and pressure air supplied to the chamber so that the sheet is released and the member moves back to its starting position. The surface 80 is formed on a head 60 attached to a stem 90 having an outer sleeve 122 secured thereto by a stud and nut 110, 126, the sleeve 122 being slidable in the member 32. Three diaphragms 120, 150, 174 are fixed to the member 32 and also to the head 60 and stem 90, the diaphragms 120, 150 defining a chamber 160 to which vacuum or pressure air can be supplied through a passage 180 to lower or raise the surface 80. A central bore 104 in the head and stem 60, 90 can also be connected to a source of vacuum or pressure air via openings 106, 129, grooves 186 and a passage 188. A diaphragm 132 encloses the lower end of the stem 90 and the space enclosed thereby is connected to the bore 104 by openings 108, 102, 130 so that unwanted pressure or vacuum does not build up in the space. The upper end of the bore 104 has a flared opening 76 to the surface 80 and also is connected by radial passages 78 in the head 60 with the space between the periphery of the surface 80 and the lip 176 of diaphragm 174. A valve 200, Fig. 1( not shown) is connected to the passages 180, 188 and is operated so that at the beginning of a feed or movement of member 32, pressure air is applied to the passage 180 and vacuum to the passage 188, so that the surface 80 is raised and vacuum applied inside the lip 176, through the opening 76 and also across the knurled surface 80, causes the bottom sheet to be gripped and moved horizontally to the feed rolls. At the end of this operation, the valve causes vacuum to be applied to the passage 180 to effect lowering of the surface 80, and pressure air to be applied to the passage 188 to effect release of the sheet from the surface 80. The valve 200 may be operated by a belt drive 206, Fig. 1, from a rotating disc 52 reciprocating the member 32 through links 44, 50. Alternatively, the member 32 in its movement may operate the valve either by rack-and-pinion mechanism or by limit switches actuated by the member 32 at the ends of its movement. A number of devices as described, and disposed transversely of the direction of feed, may be employed.

An induction motor is braked by opening contactor a to disconnect the stator winding S from supply network Ra. At the same time, contactor b closes to supply the stator winding with direct-current through rectifier Re. Added to this current, is a current derived from the rotor winding R and passing from rectifier Ps to an inverter Pt. The stator winding may be shunted by a circuit comprising resistor r1 and choke coil l1, the time constant of this circuit being equal to that of the stator winding. In another arrangement, the rectifier Re is dispensed with, and the initial excitation of the stator winding to introduce braking is afforded by control of the inverter Pt, so that, when the rotor voltage is zero, a small circulating current flows through the stator winding and the elements Pt, Ps. The inverter Pt may comprise controlled valves of the transistor type, Fig. 3 (not shown).
