Title: Volume reduction of spent radioactive ion exchange resin
IPC: C02F11/12
Filed: 1974-09-09
Abstract: A process for reducing the volume of spent radioactive ion exchange resins which have been used for conditioning water circulated through a nuclear reactor. The spent resins are discharged from the reactor system as radioactive wastes to a spent resin storage tank in the form of a slurry. The slurry is first vacuum dewatered to remove the free water and then the intrinsic water in the wet resin beads is removed by drying in a vacuum fluidized bed chamber utilizing superheated steam which also acts to fluidize the bed. Further drying is accomplished by spraying the partially dried resin and superheated steam through a steam injected two-fluid nozzle for further extraction of intrinsic water from the resins. The steam is discharged to a condenser and the dried resins to an evacuated disposal drum. Approximate 4:1 volume reductions from the resin-water slurry to the dried resin is obtainable by practicing the process.

Title: Method and apparatus for measuring and controlling the percentage reduction of ore in a moving bed gaseous reduction reactor
IPC: C21B13/00
Filed: 1976-12-31
Abstract: A method and apparatus for measuring and controlling the percentage reduction of iron ore in a vertical shaft, moving bed, gaseous reduction reactor. Reducing gas comprising hydrogen, methane, carbon monoxide and carbon dioxide is fed from a source of such gas to the bottom of the reduction zone of the reactor and is heated to an elevated temperature before being introduced into the reactor. The flow and composition of the reducing gas are determined at a first location before the gas enters the reactor. The effluent gas from the reactor is cooled and its flow and composition determined at a second location after the gas has been cooled. The measured flows and compositions are correlated with the rate of sponge iron production to obtain a measurement of percentage reduction of the ore and this measurement is used, either manually or automatically, to regulate the rate of removal of sponge iron from the reactor to maintain the percentage reduction at a predetermined desired value.

Patent ES-457712-A1 (ES)
Title: Quadrature axis field brushless exciter
IPC: H02K19/12
Filed: 1977-04-12
Abstract: Method and apparatus for accelerating a large inertia load from rest to a predetermined speed of rotation by means of a synchronous dynamoelectric machine. A synchronous dynamoelectric machine, such as a turbine generator, which is mechanically coupled to a gas turbine prime mover, is started synchronously to bring the gas turbine up to a speed which exceeds its stall speed under load. The rotor field winding of the synchronous dynamoelectric machine is connected to receive direct current excitation from a rotatable rectifier assembly of a brushless exciter. During starting, a quadrature axis winding disposed around the stator of the brushless exciter is energized by single phase alternating current. Alternating current excitation is induced by transformer action within the rotor armature winding of the exciter and is applied to the rotor field winding after being rectified by the rotatable rectifier assembly. The transformer action operates independently of the rotation of the rotor member of the synchronous dynamoelectric machine so that the brushless exciter develops direct current field excitation for starting purposes when the rotor is at rest. Polyphase alternating current excitation is applied to the synchronous dynamoelectric machine stator winding to establish a dynamic magnetic field which rotates at a speed proportional to the frequency of the applied excitation. Interaction of the static magnetic field of the rotor and the rotating stator field produces the mechanical turning force. The frequency of the synchronously applied stator excitation is increased from substantially zero cycles per second to a higher frequency until the rotor member has accelerated synchronously to the desired speed of rotation.
