Title: Genetic modification of the lung as a portal for gene delivery
Inventor: ZIEGLER ROBIN
IPC: A61P11/00
Filed: 2001-02-15
Abstract: The present invention relates to methods for treatment of systemic disorders using the lung as a depot organ for transgene delivery. Transfection of the pulmonary epithelium, particularly the deep alveolar cells, or pulmonary endothelial cells, is achieved via local administration of a transgene delivery vector to the lung. The transfected cells express the transgene, and the protein thereby expressed is communicated into the circulatory system.  Once entering into the circulatory system, the protein is able to achieve a systemic therapeutic effect.

Title: Method and apparatus for flow measurement
Inventor: BROWN GEORGE ALBERT
IPC: G01F1/7084
Filed: 2001-03-23
Abstract: A method and apparatus is disclosed for measuring the flow of fluid in the conduit, giving the example of oil in a well bore (12). A heat exchanger such as a cooling station (66) is placed in the well bore (12) and caused to create a slug of cooled oil whose passage, through the well (12) can be monitored by a temperature sensor in the form of a continuous fibre optic loop (62).  Knowledge of the movement of the cooled slug of oil and of the free cross-section of the conduit (54) wherein the oil is flowing permits the volume flow-rate of oil to be calculated. Cooling stations (66) are cooled by Joule-Thompson cooling employing high pressure nitrogen gas. Cooling stations (66) may be placed at plural locations within the well bore (12) to monitor individual flows (68) from multiple flow sources.

Title: System and method for dispensing pressurized gas
Inventor: COHEN JOSEPH PERRY
IPC: F17C13/02
Filed: 2003-02-07
Abstract: A system for dispensing pressurized gas is provided which includes a pressurized gas source, a receiving tank, a gas flow line connected between the gas source and the receiving tank, a valve for initiating and terminating flow of gas between the gas source and the receiving tank, an electronic controller, and temperature and pressure sensors for sensing temperature and pressure of gas inside the receiving tank. The electronic controller stores a tank rated density and the temperature and pressure of gas and periodically calculates a density of the gas in the receiving tank based on the temperature and pressure. The electronic controller periodically compares the density of the gas with the tank rated density and initiates flow of gas through the valve when the density in the receiving tank is below the rated density and terminates flow of gas through the valve when the density reaches the tank rated density.

Filed: 2001-11-30
Abstract: The present invention relates to an improved package, suitable for holding a treatment fluid comprising a volatile solvent. The package (1) comprises a reservoir (2) for the liquid which is sealed by a rupturable seal (7). A cap (3), coupled to one end of the reservoir, is the form of a sleeve which is axially translatable along the reservoir from first to second positions. A cutting tool (17) integrated with the cap ruptures the rupturable seal as the cap is moved from first to second positions so that the liquid can thereby be made accessible through an opening in an end wall of the cap. The package provides excellent protection for volatile liquids, yet can be easily opened by a simple press-action, instantly providing access to the liquid so that it can subsequently accessed by a liquid applicator. Also disclosed are kits comprising the package and an applicator and/or treatment fluid.

Inventor: VALENTI CRAIG F
IPC: H04B3/32
Filed: 2002-01-17
Abstract: Crosstalk between subscriber loops to transmit different broadcast services through the same bundled telephone cable is a significant limitation to providing digital subscriber line services. A method for estimating the crosstalk (300), identifying the sources of the crosstalk and predicting additional sources of crosstalk are disclosed. The crosstalk sources are identified in the frequency domain by maximizing the correlation with a "basis set" of received crosstalk PSDs (330, 340) which consists of the cascade of a finite set of known transmit PSDs types times a representative set of crosstalk couplings. Multiple crosstalk types are identified with a technique of successive spectral subtraction. This information can be used to perform crosstalk cancellation and spectrum management for DSL systems.
