Title: Remote measurement of internal temperatures through materials penetrable by microwave radiation
Inventor: ABDOLALL KHALED
IPC: G01K11/00
Filed: 1996-10-11
Abstract: A method and an apparatus remotely measures internal temperatures through materials penetrable by microwave radiation. Higher temperature areas for example in high voltage equipment may be detected through procelain clad insulators whereas most detector systems only measure the outside surface. The method comprises selecting a frequency range where the microwave radiation at least partially penetrates the materials, detecting self emitted thermal radiation through the materials for the microwave frequency range in a target beam of a passive receiver, producing signals proportional to the thermal radiation detected in the target beam, remotely scanning the target beam of the passive receiver through a target pattern, comparing the signals for different locations in the target pattern to identify locations emitting higher thermal radiation, and processing the signals to provide an indication of internal temperature for the locations emitting higher thermal radiations.

Abstract: A method and apparatus for mixing two or more materials which are difficult to mix. The dispersion apparatus has a cylindrical housing (20) which is divided into an upper chamber (42) and a lower chamber by a separator (40). The materials to be mixed are forced under pressure into the lower chamber which is divided into pressure zones (64) by kinetic baffles (58). A turbine blade (66) imparts energy to the liquids which are kept from swirling by the kinetic baffles (58). The high pressure of the materials introduced into the chamber forces the materials through an opening (44) between the baffle (40) and shaft turning blade (66) into the upper chamber (42). In the upper chamber (42), a second blade (80) imparts centrifugal force to the materials to force them outward. The materials are sheared as they move through the apparatus and then are delivered to an outlet (50).

Title: Speech playback speed change using wavelet coding, preferably sub-band coding
Inventor: LIN LIN
IPC: G10L19/02
Filed: 1998-09-30
Abstract: A method of speeding up playback of a digitised audio signal without raising the pitch and without introducing discontinuities in the speech signal, comprises sub-band coding (SBC) consecutive blocks of the audio signal with standard SBC or wavelet compression to derive frames of data. Next periodic adjacent pairs of the frames are dropped to leave a stream of remaining frames. A sped up approximation of the digitised audio signal is then reconstructed by sub-band decoding consecutive remaining frames. The method can also be used to slow speech playback by replicating, rather than dropping, adjacent pairs of frames.

Title: Dry-pit submersible pump and liquid transfer method
Inventor: QANDIL MARK M
IPC: H02K9/14
Filed: 1998-10-02
Abstract: A dry-pit submersible pump using a totally enclosed fan-cooled (TEFC) electric motor to power the pump. A release mechanism prevents the fan from creating excessive drag when submerged in water. The fan cools the motor when the water level is below the motor, and the surrounding water combines with the fan to cool the motor when the water level rises to at least partially surround the motor. When the fan is at least partially submerged, the release mechanism substantially prevents the fan from imposing a load on the motor due to the surrounding water. The release mechanism can take the form of a shear key, a torque-release clutch or flexible fan blades.

Title: Method for the detection, identification, enumeration and confirmation of circulating cancer cells and/or hematologic progenitor cells in whole blood
Inventor: LEVINE ROBERT A
IPC: G01N33/574
Filed: 1998-11-12
Abstract: A method for analyzing blood enables one to isolate, detect, enumerate and confirm under magnification the presence or absence of target cancer cells and/or hematologic progenitor cells which are known to circulate in blood. The analysis is performed in a sample of centrifuged anticoagulated whole blood. The analysis involves both morphometric and epitopic examination of the blood sample while the blood sample is disposed in a centrifuged blood sampling tube. The epitopic analysis of the presence or absence of cancer cells relies on the detection of epitopes which are known to present only on cancer cells; and the epitopic analysis of the presence or absence of hematologic progenitor cells relies on the detection of epitopes which are known to present only on hematologic progenitor cells. The targeted epitopes on the target cell types are epitopes which are also known to be absent on normal circulating blood cells; and the target cancer cell epitopes are epitopes which are known to be absent on target hematologic progenitor cells. Fluorophors with distinct emissions are coupled with antibodies which are directed against the targeted epitopes. The morphometric analysis is performed by staining the cells in the blood sample with an intracellular stain such as acridine orange which highlights the intracellular cell structure. Both the morphometric and epitopic analyses are preferably performed at or near the platelet layer of the expanded buffy coat in the centrifuged blood sample. The morphometric analysis and/or the epitopic analysis may be performed under magnification both visually and/or photometrically.
