  • Patent number: 5222998
    Abstract: A device can be provided in different embodiments for holding different tensions in different length string sections of a sports racquet stringing bed. In one embodiment, a strip of material is applied on the periphery of the head portion of the racquet and is compressed under the string portions extending between pairs of adjacent stringing holes. In another embodiment, the tension holding device is a plurality of cylindrical bands of compressible material which fit about the string portions and within the grommets of the racquet. In both embodiments, the material is compressed by the string portion to generate sufficient frictional force therebetween to prevent slippage of the string portion relative thereto and thereby hold the different length string sections under the predetermined amount of differential tension.

  • Patent number: 5200138
    Abstract: A spectral shift-producing subassembly is composed of a plurality of sealed empty water displacement rodlets incorporating a spectral shift-producing capability. Each of the rodlets includes an elongated tube sealed at its opposite ends and having an axially-extending annular wall section of reduced thickness compared to the thickness of the wall of the remainder of the rodlet. The respective reduced thicknesses of the axial wall sections of the rodlets can be varied to adapt the rodlets to rupture at different times and permit water to enter the rodlets to produce an increase in the water/fuel ratio and thereby an increase in reactivity. The rodlets can also have different levels of pressurization to initiate rupture at different times.

  • Patent number: 4783311
    Abstract: Nuclear fuel elements are provided that are resistant to pellet-clad interaction. The closed end nuclear fuel elements comprise a zirconium or zirconium alloy tube that has a layer of lubricant, preferably graphite, on the inner surface thereof, and enriched uranium dioxide pellets that have a coating on the outer surface thereof of a thickness sufficient to absorb fission products. The coating on the pellets may be a burnable absorber or a material that has a relatively low neutron absorption compared to a burnable absorber. The combination of the layer on the tube and the coating on the pellets reduces both the stress level and the concentration of damaging fission products that would contact and react with the layer of lubricant about the inside surface of the tubular cladding and thus reduces conditions for pellet-clad interaction.

  • Patent number: 4744942
    Abstract: Spacer grids for a nuclear fuel assembly are arranged in superadjacent groups having grid springs and opposing dimples which contact a fuel rod passing through a cell of the spacer grid with a selected spring force. As fabricated, the lowermost grid exerts the greatest initial spring force on the rod; intermediate grids exert a smaller spring force; and the uppermost grid exerts yet a lower spring force. The fuel rod is supported laterally while it is permitted to age expand axially with little axial compression resulting from the spring forces of the springs and dimples, whereby bowing of the rod is diminished.

  • Patent number: 4687621
    Abstract: An improved spectral shift-producing rod in a fuel assembly of a nuclear reactor has an elongated hollow tubular body with a pair of end plugs attached to its opposite ends to hermetically seal the rod. A burnable poison material is contained in the hollow body. The material generates a gas within the body as operation of the reactor proceeds. Also, the material is soluble in moderator water when brought into contact with the same. The rod has a weakened structural region which is subject to rupture at a given level of internal pressure. Preferably, the weakened region takes the form of a thinned disc-like portion formed in at least one of the end plugs. The water soluble material within the rod depresses power initially by absorbing neutrons. Absorption of neutrons causes generation of helium gas which increases internal pressure within the rod. When the internal pressure exceeds the rupture strength of the weakened region of the rod, the hermetic seal is broken and water enters the rod.
