Title: Fuel elements for nuclear reactors
IPC: G21C3/16
Filed: 1965-12-01
Abstract: 1,118,332. Fuel elements. UNITED STATES ATOMIC ENERGY COMMISSION. 1 Dec., 1965 [7 June, 1965], No. 50896/65. Heading G6C. A fuel element comprises an elongated tubular cladding having upper and lower closed ends defining a fuel zone in which from two to five fuel segments are serially arranged, each segment having one end fixed relative to the cladding and the other end free to slide within a void space containing a spring. The segments are thus free to thermally expand and contract in unison in the same direction. In the case of the two-segment fuel element, the void at the top of the lower segment is above the transverse mid-plane of the element and the segments are of unequal length, whereas in the case of the three-, four-, and five-segment fuel elements, the segments are of equal length. The thermal expansion coefficient of reactivity approaches zero with an increase in the number of fuel segments, reaching zero when there are four segments. An increase beyond five segments results in the coefficient remaining near zero or going slightly positive with the disadvantage that an excessive amount of neutron-absorbing material is introduced into the fuel element. The use of such fuel elements in a reactor greatly simplifies the control of reactivity excursions by means of Doppler broadening. Each fuel segment may comprise a plurality of serially arranged subsegments, each subsegment being an individually clad compact containing fissile fuel, e.g. UO 2 , PuO 2  or a mixture of these. In a particular sodiumcooled fast reactor, the fuel comprises U-238 (1598 kg.), Pu-239 (296 kg.) and Pu-240 (26 kg.) in UO 2 -PuO 2  form clad in stainless steel. The elongated tubular cladding contains upper and lower end reflectors, e.g. Ni or C, and insulator pellets, e.g. Al 2 O 3 , MgO or sapphire, at each end of the fuel segments. The fuel segments are arranged in hexagonal arrays around central moderator rods of BeO. An extension rod is coupled to the upper end of each element to facilitate its insertion into and removal from the reactor core.

For signals at 60 or 50 fields per second the film is recorded at 72 or 75 frames per second respectively. a colour film then being produced, each colour frame being produced from the three black and white frames relating to one field to produce a colour film at 24 or 25 frames per second. For the 50 fields per second non-interlaced embodiment each second field is recorded whereas for the 60 fields per second non-interlaced embodiment, Fig. 3, two out of every five fields are recorded. A video disc 108 may be used to provide the correct delays for sequential recording of the colour components by an electron beam recorder 25. The edges of each recorded field are discarded and the disc revolves at 219 lines per revolution. The first field is recorded by head 104 and the third field is recorded by head 106 to delay this field by 131 lines relative to the first field. The electron beam of recorder 25 is deflected vertically by signals from deflection circuitry 56 so as to compress each frame to provide spaces between the frames, and also to adjust the position of each recorded frame. Video disc 108 may be dispensed with if three electron beam recorders are provided spaced along the film 30 to record the green, red and blue components simultaneously, the beams being deflected along the film to produce the equivalent of the 131 line delay between heads 104 and 106. For the 50 fields per second interlaced embodiment every field is recorded and for the 60 fields per second interlaced embodiment four out of every five fields are recorded, a video disc (242, Fig. 5, not shown) with two tracks being used for the necessary delays, the electron recording beam being spot wobbled in synchronism with a switch which is switched between the signals of the corresponding colour component of the interlaced fields which are to be recorded on one frame. Delay lines, storage tube delays or digital storage delay means may be used instead of video disc 108. The film 30 may be recorded by cathode ray tube exposure or laser beam exposure rather than electron beam exposure.

Abstract: 1370781 Torque wrench BROOM & WADE Ltd 10 Nov 1971 [10 Nov 1970] 53483/70 Heading B3N [Also in Division F2] A torque applying device comprises a motor 20 and a torque delivery means 22 adapted to shut off the motor at a predetermined torque. The means 22 has a rotor 32 driven by motor spindle 33 through a safety clutch 34. The free end of the rotor is splined to take the sun wheel of an epicyclic gear. A planet carrier 54 has planet wheels 53 and is drivingly connected to an output shaft 57 by a further epicyclic reduction gear 58. The ring gear 59 of the first mentioned epicyclic gear is releasably held against rotation in clutch housing 46. This is achieved by a plurality of balls 10 engaging in sockets in the ring gear. The balls being biased by a spring 65 through a flange 12 and pins 11. At a predetermined torque balls 10 are forced out of engagement with the ring gear. This causes movement of collar 13, bearing 45 and flanged collar 15. Movement of the collar causes pin 16 to move push-rod 17 which opens valve 9. Thus a chamber 8 is vented to atmosphere as is passage 29. Air pressure in chamber 4 moves valve 5 against spring 26 cutting off air to the motor. The position of valve 5 is maintained until valve 3 is closed so that air pressure in chamber 4 can bleed away via capillary hole 7. After such venting spring 26 will return the valve to its start position. Adjustment of the loading of spring 65 is by positioning of collar 74. Safety clutch 34 is set to be effected by a torque higher than said predetermined torque and acts to disengage the drive connection between rotor 32 and spindle 33.
