Title: Interferometer and method for compensation of dispersion or increase in spectral resolution of such an interferometer
Inventor: DULTZ WOLFGANG
IPC: G01B9/02
Filed: 1997-08-01
Abstract: The invention concerns a double-beam interferometer (1) for electromagnetic radiation and a method for the compensation of dispersion or increase in the spectral resolution of such an interferometer. Using a polarizer (8), which is brought into the optical radiation path, a defined polarization state P1/2 0 is produced for the electromagnetic partial waves flowing into the arms of the interferometer.      This polarization state is wavelenght-independent and can vary for both partial beams. Optical elements (11, 12) modify the polarization state P1/2 0 of the electromagnetic partial waves as a function of wave-length .lambda. and each spectral component .lambda.i is coded with a polarization P~1/2 ?(.lambda.i). An analyzer (9), fitted to the output of the interferometer, transmits an adjustable polarization state P det, whereby an additional wavelength-dependent phase difference .gamma.(.lambda.) occurs between the partial waves of the spectral components. .gamma.(.lambda.) can be adjusted to obtain compensation of dispersion or an increase in the spectral resolution of the interferometer.

Patent CA-2265429-A1 (CA)
Inventor: KINSINGER GRIFF H
IPC: F16C17/22
Filed: 1999-03-11
Abstract: The invention provides a submersible pumping system which includes a motor containing self-centering rotor bearing assemblies. Each rotor bearing assembly in accordance with the present invention includes a sleeve, a journal, and at least two seals. The journal is preferably disposed about the sleeve which is keyed to the power transmission shaft of the motor. The journal has a peripheral surface which is configured to have at least two circumferential support regions which are spaced apart from one another. Each of these circumferential support regions supports a corresponding seal. Each seal includes an interface member and an activating member. When in place in a rotor section of a submersible pump motor, the seals frictionally engage the inner surface of the stator and exert a centering force against the journal and thus against the bearing sleeve and the power transmission shaft.  The seals also exert a force against the inner surface of the stator which prevents rotation of the journal when the power transmission shaft is rotating.

Title: Synthesis and evaluation of two technetium-99m-labeled peptidic 2-nitroimidazoles for imaging hypoxia
Inventor: BALLINGER JAMES R
IPC: C07K7/06
Filed: 1999-03-19
Abstract: The presence of hypoxic cells in solid tumors is a marker for therapy resistant, aggressive disease. The non-invasive detection of hypoxic cells in tumors by radiolabeled 2-nitroimidazoles is a diagnostic technique under current evaluation. Two peptidic chelating agents, dimethylglycyl-L-seryl-L-cysteinyl-lysyl{N E-[1-(2-nitro-1H-imidazolyl)acetamido]}-glycine (RP435) and dimethylglycyl-tert-butylglycyl-L-cysteinylglycine-[2-(2-nitro-1H-imidazolyl)ethyl]amide (RP535) have been synthesized.  Both chelating agents contain an N3S class chelator for 99m Tc and Re, and a 2-nitroimidazole group which can be enzymatically reduced and trapped in cells under hypoxic conditions. Two isomers of 99m TcO-RP435, which are assumed to be syn and anti conformations, have been observed on HPLC analysis. The interconversion of the two isomers in aqueous solution was investigated. In contrast, RP535 chelates 99m Tc to form a single isomer and no conversion to its counterpart has been observed on HPLC analysis. The tert-butyl group on the chelator may inhibit the formation and interconversion of the syn and anti isomers of 99m TcO-RP535. Both tracers showed a significant degree of hypoxia-specific accumulation in an in vitro assay, with 99m TcO-RP535 showing higher selectivity for hypoxic cells than 99m TcO-RP435.  These results suggest that 99m TcO-RP535 represents a lead compound worthy of further investigation as an agent for imaging hypoxia in tumors.

Title: Method and apparatus for manufacturing products through the use of waste materials of various kind, and product obtained therewith
Inventor: BERTOGLIO MARIO
IPC: B29B17/00
Filed: 1999-04-08
Abstract: A method and an apparatus for manufacturing products through the recycling of waste materials and whereby the optional addition of raw materials may occur. The waste materials and optionally used raw materials are first shredded into small-sized particles, preferably from 1 to 10 mm in size, and then mixed together to form a first blend that constitutes a first component of each product, which is adapted to form the inner, non-visible portion, or core, of each product, and a second blend which constitutes a second component of each product, and which is adapted to coat the inner portion and form the outer visible portion, i.e. skin, of each product. The first and said second blends are subsequently heated separately from each other, following addition to the first blend of heat stabilizing means and blowing means adapted to cause the first blend to swell or foam during heating, as well as the addition of colouring means to said second blend. Heating takes place to a temperature of approx. 180 to 210°C, thereby achieving first and second plasticized masses. Constituents having higher melting temperatures than said pre-determined heating temperature are incorporated in the masses where they behave like inert filling materials. The first and said second plasticized mass are then injected simultaneously into a moulding means reproducing the shape of the respective products, thereby homogeneously mixing with each other so that the lower density, higher fluidity compound forms the outer portion and the higher density, lower fluidity compound forms the inner portion of the product.

Title: Electronic tide meter, method for calculating a high/low tide time and recording medium with a program for executing the same method
Inventor: NAKAMURA CHIAKI
IPC: G04B19/26
Filed: 1999-06-08
Abstract: An electronic tide meter which calculates a high tide time and low tide time with accuracy, and a high tide/low tide calculating method are disclosed. A tide level estimating equation is fixed by performing calendar input and selection of a region through an input section and reading tide data of the selected region from a ROM stored with tide data for each region. First tide data is determined with a first time interval from the tide level estimating equation in the CPU, and further second tide data is determined with a second time interval shorter in time interval than the first time interval. Accordingly, from the first tide level data a range is extracted in which the sign in displacement between those of the first tide level data so that tide data at a fine time interval can be determined only for the range. From the tide level data a high tide time and low tide time is calculated with accuracy.
