  • Publication number: 20090022259
    Abstract: A fuel rod includes a cladding tube with a wear-inhibiting coating. In one embodiment, the coating is made of a metallic powder material that is applied to the exterior surface of the cladding tube using a thermal spray process. In an alternative embodiment, the coating is a composite made of a metallic powder material, and a ceramic powder material or a metal oxide hard phase powder material that is simultaneously applied with the metallic powder material to coat the cladding tube. The coating can be applied to selected areas of the fuel rods where debris tends to fret the fuel rod.

  • Publication number: 20070153963
    Abstract: A zirconium alloy suitable for forming reactor components that exhibit reduced irradiation growth and improved corrosion resistance during operation of a light water reactor (LWR), for example, a boiling water reactor (BWR). During operation of the reactor, the reactor components will be exposed to a strong, and frequently asymmetrical, radiation fields sufficient to induce or accelerate corrosion of the irradiated alloy surfaces within the reactor core. Reactor components fabricated from the disclosed zirconium alloy will also tend to exhibit an improved tolerance for cold-working during fabrication of the component, thereby simplifying the fabrication of such components by reducing or eliminating subsequent thermal processing, for example, anneals, without unduly degrading the performance of the finished component.

  • Publication number: 20060142368
    Abstract: Compounds useful for inducing apoptosis in proliferative cells, particularly cancer cells, including but not limited to prostate cancer, leukemia, non-small cell lung cancer, colon cancer, CNS cancer, melanoma, ovarian cancer, renal cancer, bladder cancer, lymphoma, and breast cancer. These compounds are particularly useful in the treatment of androgen-independent cancers, including hormone-refractory prostate cancer. Further provided are methods of treating cancer in a subject in need of such treatment using the compounds of the present invention. Further provided are methods for using the compounds of the present invention to treat, inhibit, or delay the onset of cancer in a subject. Further provided are methods of inducing apoptosis in rapidly proliferating cells, particularly, though not necessarily cancer cells, using the compounds of the present invention.

  • Publication number: 20060048870
    Abstract: Disclosed herein are zirconium-based alloys and methods of fabricating nuclear reactor components, particularly fuel cladding tubes, from such alloys that exhibit improved corrosion resistance in aggressive coolant compositions. The fabrication steps include a late-stage ?-treatment on the outer region of the tubes. The zirconium-based alloys will include between about 1.30 and 1.60 wt % tin; between about 0.06 and 0.15 wt % chromium; between about 0.16 and 0.24 wt % iron, and between 0.05 and 0.08 wt % nickel, with the total content of the iron, chromium and nickel comprising above about .31 wt % of the alloy and will be characterized by second phase precipitates having an average size typically less than about 40 nm. The final finished cladding will have a surface roughness of less than about 0.50 ?m Ra and preferably less then about 0.10 ?m Ra.

  • Publication number: 20060048869
    Abstract: Disclosed herein are zirconium-based alloys that may be fabricated to form nuclear reactor components, particularly fuel cladding tubes, that exhibit sufficient corrosion resistance and hydrogen absorption characteristics, without requiring a late stage ?+? or ?-quenching processes. The zirconium-base alloys will include between about 1.30-1.60 wt % tin; 0.0975-0.15 wt % chromium; 0.16-0.24 wt % iron; and up to about 0.08 wt % nickel, with the total content of the iron, chromium and nickel comprising at least about 0.3175 wt % of the alloy. The resulting components will exhibt a surface region having a mean precipitate sizing of between about 50 and 100 nm and a Sigma A of less than about 2×10?19 hour with the workpiece processing generally being limited to temperatures below 680° C. for extrusion and below 625° C. for all other operations, thereby simplifying the fabrication of the nuclear reactor components while providing corrosion resistance comparable with conventional alloys.

  • Patent number: 6949713
    Abstract: A lighting system having a vibration switch for a footwear is disclosed. The system comprise a vibrating switch turning “on” or “off” responsive to motions of the footwear. The vibrating switch further comprises an isolating housing, a spring on the isolating housing, one end of the spring being a free end and another end thereof being a fixing end, a conductive plate in the isolating housing; a metal support plate in the isolating housing and being at another side of the conductive plate; and a first and a second pins; the first pin being connected to the conductive plate and extending out of the isolating housing; and the second pin connected to the metal support plate and extending out of the isolating housing. When the isolating housing vibrates, the free end of the spring will swing to contact the conductive plate so as to conduct current to the conductive plate.

  • Publication number: 20050147543
    Abstract: The present invention is a photocatalysis water purifying device that provides an excellent purging water quality feature. The outermost part of the device is equipped with a light-pervious cover; the inner part of the device has an ultraviolet tube. Furthermore, a photocatalysis membrane is clothed outside the light-pervious cover. Due to the direct application of the photocatalysis membrane on the ultra violet tube and the utilization of the silica gel to seal up the opening for water-resistance purposes, this device can be put in the water alone with the tube and thereby effectively provides the antibacterial and germ-eliminating functions based on the stimulation between violate-rays and photocatalysis. Moreover, the device can be used together with an air-supplier to assist the chemical reaction of photocatalysis.

  • Patent number: 5789716
    Abstract: A one-way shaking switch including a housing, a steel ball, a spring, a cover board and an upper and a lower metal terminals. The housing is integrally formed with a circular cavity, a transverse cavity and a longitudinal rectangular cavity disposed therebetween. Two steps are formed on two sides of the housing. Two pairs of posts are respectively symmetrically disposed on the steps. The lower terminal is fixedly inserted in the transverse cavity, the steel ball is placed in the circular cavity while the spring is disposed in the rectangular cavity. One end of the spring rides over a terminal leg of the lower terminal. The other end of the spring is disposed with a ring member depressing or retaining the steel ball. The upper terminal is placed on the steps of the housing over the lower terminal. The cover board is fixedly overlaid on the housing to secure the above elements in the housing.
