Title: Pressurized fuel elements for nuclear reactors
IPC: G21C3/16
Filed: 1973-01-22
Abstract: 1374944 Fuel elements WESTINGHOUSE ELECTRIC CORP 22 Jan 1973 [16 Feb 1972] 3153/73 Heading G6C A fuel element comprises a sealed casing 26, e.g. of Zr alloy, which contains between the upper end plug 18 and the fuel pellets 24 a pressurized gas-filled plenum 12. A collapsible capsule 14, e.g. of stainless steel, which is disposed within the plenum 12, being suspended from the end plug 18 within a retaining spring 20, is designed to gradually collapse upon an increase in pressure within the plenum 12 above a predetermined value in order to maintain the plenum pressure substantially constant. An initially collapsed portion is provided at one end of the capsule 14 in the form of a dimple 16 machined in the capsule wall. When the internal pressure exceeds the predetermined value, collapse beyond that provided by the dimple 16 occurs and a slight reduction in internal pressure results. As more fission gas is generated the pressure will increase and the capsule will gradually collapse at what may be termed running collapse pressure. The internal pressure will then be maintained at a substantially constant level because as more fission gas is released, the collapse will propagate along the length of the capsule (Figs. 2, 3 and 4, not shown) at a rate sufficient to maintain substantially constant internal pressure.

Filed: 1944-02-25
Abstract: 594,344. Electron oscillators. WESTERN ELECTRIC CO., Inc. Feb. 25, 1944, No. 3579. Convention date, Dec. 15, 1942. [Class 39 (i)] Electrons or ions are caused to execute simple harmonic oscillations about a reference plane between two electrodes connected together. Between each electrode and the reference plane is a group of electrodes coupled together resistively and capacitatively so that a parabolic static field is produced between the reference plane and each electrode, a highfrequency circuit being connected between the groups of electrodes. In a high potential generator, the electrodes 13, Fig. 2, are mounted within a high potential shield 14 which also contains the electron source 12 and two groups 15 of electrodes coupled capacitatively by their flanges 16 and resistively by resistors 21 so selected that the resistance from any electrode to earth varies as the square of that electrode's distance from the cathode. When high-frequency potentials are applied to the electrodes 15 through coaxial lines 18, the correctlyphased electrons emitted by the cathode perform harmonic oscillations of ever-increasing amplitude until they strike the collectors 13 ; the collected current flowing through the resistors 21 produces the required bias potentials and it is shown that these potentials may reach several million volts. Magnetic focusing may be produced by annular permanent magnets 23 mounted on each electrode, or by an external coil. Discs 22 shield the cathode from the oscillating cloud of electrons. Each group may be made to resonate by making its length a quarter wavelength or an odd multiple. In an oscillation generator, electrons from cathode 12, Fig. 3, oscillate between electrodes 28 across the gap 25 in a resonator 26, groups of electrodes 15 being provided as before. Correctly phased electrons perform harmonic oscillations of ever-decreasing amplitude, giving up energy to the resonator at each transit of the gap.

Abstract: 308,964. Soc. L'Auxiliare des Chemins de Fer et de l'Industrie. April 2, 1928, [Convention date ]. Addition to 290,598. Feedwater, heating. - The regulator valve of the exhaust steam supply to the heater chamber of the parent Specification is modified to be shut on stoppage of - the steam pressure from the main engine exhaust or the feed pump. In Fig. 1 the main regulator valve 43 normally held open by the spring 41 is caused to shut if the pressure in the heaterchamber rises by the action of the piston 42 forced down by pressure communicated through the pipe 40. A separate piston or pistons 60, 61 is kept in raised position under the pressure of the. main engine or feed pump exhaust, through connections 58, 59. If one or both fail, as when the engine is shut off, the piston falls and a finger 64 or 65 depresses the stem 66 and main valve 43. The control may be effected mechanically as in Fig. 5 where the feed-pump piston rod causes a crank 82 to rotate, a roller running up the cam contour 99 forces the cone 87 against a spring 88 and a bell-crank lever 90 causes a pull on a cable 94 whereby a lever 95 is held out of contact with the stem 66. On stoppage of the feed pump the cone is moved by the spring, the tension on the cable is relieved and the lever depresses the spindle 66 and the attached regulator valve. Provision is made for bye-passing the exhaust from other auxiliaries, which normally would go to the heater chamber, for example the air compressor, to the atmosphere on stoppage of the feed pump.

Abstract: 1,237,604. Direction-responsive switches. CROUZET. 22 Jan., 1969 [22 Jan., 1968], No. 3726/69. Heading HlN. A device for selecting the direction of rotation of a synchronous motor 2, of the single-winding magnetized-rotor kind which is self-starting in a random direction, comprises a selector switch KS for energizing the winding of motor 2 via a selected one of two spring-blade contacts 11 and 12 which is opened if the motor starts in the wrong direction. The motor 2 drives a pinion 7 on a shaft 1 on which is freely pivoted a rocker 3 carrying an idler pinion 8 in mesh with pinion 7. When the motor starts the inertia of pinion 8 causes the rocker to tilt and a projection 4 thereon opens the respective one of contacts 11, 12 which, if it is the energized one, causes the motor to stop, whereupon the rocker is restored and the motor starts again-this action recurring until the motor starts in the desired direction. In the embodiment of Fig. 1 (not shown), the motor output is taken off the pinion 8 which rocks to mesh with a different gear train for each direction of running, and in order to maintain the rocker 3 tilted after starting an oscillating-anchor escapement (13, 14) is provided as a brake on pinion 8.
