Title: Modular fuel element adaptable to different nuclear power plants with cooling channels
Inventor: FLORIDO PABLO CARLOS
IPC: G21C3/30
Filed: 2000-05-02
Granted: 2012-03-20
Abstract: The present invention relates to a modular nuclear fuel element, which can be adapted by an assembly system allowing it to be used in different nuclear power plants with horizontal and vertical cooling channels. The module is a cluster of parallel fuel rods mounted as circular concentric crowns and supported by a structural system. It has a single diameter fuel rod array where the ratio of the heat transfer surface defined per unit length to the transverse rod cross section is higher than 330. It also has self-supporting fuel element spacer grids, which are collapsible sheaths attached to them with fewer than 13 welded end stoppers.  The number of these fuel rods is higher than 43. The length of the module is the largest compatible length with the refuelling machine, to reduce the hydraulic restrictions caused by structural endings, and to be able to balance this by providing a fuel element having a larger cooling area. This will maintain the hydraulic restriction and the current total fuel mass in the channel. The modular fuel element may contain fuel material combinations with different uranium and/or plutonium isotopic concentrations, and/or any other nuclear fuel material (actinides, nuclear poisons, fission products or fuel material coming from other nuclear reactors). The utilisation of the fuel modules individually in the pressurised heavy water reactors with horizontal fuel channels is an application of the present invention. Another application would involve the assembling of several fuel modules in nuclear reactors with vertical fuel channels.

Title: N x m digitally programmable optical routing switch
Inventor: WU KUANG-YI
IPC: H04B10/43
Filed: 1999-04-16
Granted: 2002-10-01
Abstract: An optical routing switch provides polarization-independent, low-crosstalk between any input port (500, 501) and any output port over a wide operating range of temperatures and wavelengths. Optical signals at each input (500, 501) are spatially decomposed into two orthogonally-polarized beams by a first polarization-dependent routing element (30). This beams are routed through optical switches, which each includes: (1) a switchably controlled polarization rotator (100) so that both of the emergent beams are either horizontally or vertically polarized based on the control state of the device;  and (2) a polarization-dependent routing element which routes the beams based on polarization. These beams are then input to an array of polarization rotators that change the polarization of at least one of the light beams, so that the two beams are orthogonally polarized. A polarization-dependent routing element (60) intercepts the two orthogonally-polarized beams and recombines them to exit at the selected output port.

Title: Applicator for applying and distributing substances to target surfaces
Inventor: GIRARDOT RICHARD MICHAEL
IPC: A45D40/26
Filed: 1999-06-30
Granted: 2007-10-30
Abstract: The present invention provides an applicator for applying and distributing a substance onto a target surface. The applicator comprises a substantially planar sheet of compressible, conformable material having opposed first and second surfaces and an interior region between said first and second surfaces. The sheet of material has a thickness between the first and second surfaces which decreases when the sheet of material is subjected to an externally-applied force in a direction substantially normal to the first surface. The applicator further includes at least one discrete reservoir extending inwardly of the first surface into the interior of the sheet of material which is at least partially filled with a substance and at least one discrete aperture formed in the first surface which is in fluid communication with the reservoir.  Compression of the sheet of material via an externally-applied force substantially normal to said first surface expresses product from the aperture and translational motion of the first surface relative to a target surface applies and distributes said product onto the target surface. In a preferred embodiment, a plurality of apertures are associated with corresponding reservoirs forming a delivery zone near one end of a hand-held applicator, and the sheet material is preferably resilient both in compression and in bending to conform to irregular target surfaces. A wide variety of substances are contemplated, including particularly antiperspirant/deodorant products. Other embodiments include a single reservoir feeding a plurality of apertures.
