Title: System for monitoring and treating sleep disorders using a transtracheal catheter
Inventor: CHRISTOPHER KENT L
IPC: A61B5/00
Filed: 1998-10-15
Abstract: An apparatus for augmenting ventilation of a patient (100) and monitoring the patient's breathing patterns uses a transtracheal catheter (10). A substantially constant flow of oxygen/air is supplied through one of the lumens (12) of the transtracheal catheter (10) into the patient's tranchea (101) to augment the patient's spontaeous breathing.      A respiration sensor (80, 82, 85 or 87) measures a predetermined physical property (e.g., pressure or flow rate) related to the patient's respiration at the distal end (17) of the transtracheal catheter (10). This data is recorded to monitor the patient's respiration patterns over time for subsequent analysis. The respiration data can be recorded on a strip chart or stored in digital form for transmission by modem or removable data storage media to a remote facility for analysis. A capnometer (87) can be connected to one of the transtracheal catheter lumens (16) to measure the carbon dioxide concentration of the air exhaled by the patient (100). The distal end of the transtracheal catheter (10) can also be equipped with an oximetry probe (85) that contacts the lining of the patient's trachea (101) to measure blood oxygen saturation. The oximetry data is recorded concurrently with the respiration data and used for diagnosis and monitoring of sleep disorders, such as sleep apnea and hypopnea.

Title: Modified heat shock protein-antigenic peptide complex
Inventor: SPIELMAN JULIE
IPC: C12N1/21
Filed: 1999-02-19
Abstract: The present invention relates to methods for purifying immunogenic, prophylactically and therapeutically effective complexes of modified heat shock proteins noncovalently associated with antigenic peptides of cancer or infected cells. The claimed methods comprise the constructing of a nucleotide sequence encoding a secretable modified heat shock protein, expressing the sequence in an appropriate host cell, recovering the immunogenic complexes from the cell culture and the cells, and purifying the immunogenic complexes by affinity chromatography. Large amounts of such immunogenic complexes can be obtained by large-scale culturing of host cells containing the genetic sequence. The complexes can be used as a vaccine to elicit specific immune responses against cancer or infected cells, and to treat or prevent cancer or infectious diseases.

Title: Dual cutting mill
Inventor: HOLLAND JIMMIE J
IPC: E21B10/08
Filed: 2000-10-27
Abstract: A rotating tool for milling or drilling in a well bore, having one or more rotating cutting structures, with each cutting structure rotating about its own axis, and with the cutting structures rotating about the axis of the tool. The rotational axis of the tool is offset from the axis of at least one cutting structure, with the axis of the tool passing through that cutting structure. This ensures that the cutting structure which spans the axis of the tool rotates independently of the tool, to prevent the existence of a zero velocity point on the cutting face of the tool.

Title: Downhole screen with tubular bypass
Inventor: PETERSON ELMER R
IPC: E21B34/06
Filed: 2000-11-10
Abstract: A system for preferable use in gravel packing is disclosed which includes a plurality of transport tubes which are mounted outside of gravel pack screens.  The multiplicity of shunt tubes cover a particular zone so that the tubes have a varying length to deposit gravel at different portions of the zone. The tops of the tubes are preferably sealed until ready for use and activated by applied pressure. In the preferred embodiment, rupture discs are found at the tops of each of the tubes, set for different pressures so as to open up the transport tubes to the lower most portion of a particular zone and later in sequence to the higher-most portion. The transport tubes are affixed to each section of pipe and are made up when two sections of pipe are made up to alignment marks. When the marks are aligned, the transport tube segments from each pipe section are in an aligned and sealed relation while the tool joint is properly torqued.

Title: Mechanical compression release
Inventor: DIETZ JAMES R
IPC: F02N99/00
Filed: 2000-11-17
Abstract: A compression release mechanism for an internal combustion engine wherein a rotatable pin positioned axially parallel to the camshaft is rotatably received in the cams, and has a lift member mounted at an axial end thereof. The pin is non- cylindrically shaped at one axial end thereof, and the non-cylindrically shaped end is received and secured into a correspondingly shaped bore disposed in a cylindrical hub extending perpendicularly from a one-piece flyweight. An optional adhesive can be used to secure the pin to the hub of the flyweight. According to a further optional embodiment, the hub can be crimped so as to engage the release pin. The disclosed configuration ensures a secure engagement and therefore avoids slipping between the release pin and the flyweight. Further, the design facilitates easy alignment of the pin with the flyweight during assembly. The flyweight can be a one-piece integral structure.
Patent CA-2331155-A1 (CA)
Inventor: FRANEY JOHN PHILIP
IPC: H04B1/10
Filed: 2001-01-16
Abstract: A method and apparatus are disclosed for suppressing interference in a radio frequency (RF) communication system using active shielding techniques.  An opposing neutralizing signal is applied to actively neutralize stray signals in a microwave communication environment. An interfering or stray signal is detected using a sensing antenna, and the opposing neutralizing signal is generated in response thereto. The opposing neutralizing signal is applied to a signal neutralizing shield to shield any desired components or devices. The opposing neutralizing signal is approximately 180 degrees out of phase, and of equal magnitude to the detected interfering signal. A  phase shifter/null feedback device receives the detected stray signal, if any, and adaptively adjusts the phase and magnitude of the opposing neutralizing signal. In one embodiment, the phase shifter/null feedback device includes an integrator that generates a DC value that is proportional to the energy of the interfering signal. The DC value is applied to a voltage controlled oscillator (VCO) using known feedback techniques to adjust the phase or magnitude, or both, of the opposing neutralizing signal and to thereby minimize the DC value.
