Title: Meter enclosure cover
Inventor: MCGRAIL KENNETH W
IPC: B65D85/86
Filed: 2004-02-11
Abstract: The meter enclosure cover includes a cylindrical tube attached to a cover, which allows the face of the meter to be exposed while maintaining the meter at a low profile in the meter enclosure. The cylindrical tube has a flange on one end to provide a surface on which a gasket can be attached. The angle at which the cylindrical tube meets the cover can vary to allow for proper meter viewing as well as protection from water.  The flange on the cylindrical tube rests firmly against the circumference of the meter base. All faces of the meter enclosure cover which contact the meter and meter enclosure are sealed by a continuous gasket to protect against dirt, dust, oil and water. The meter enclosure cover is attached to the meter enclosure with a secure locking device. Construction of the meter enclosure cover can be from any appropriate material. Construction methods for the meter enclosure cover include (but are not limited to) cloth lay-up molding, thermoforming, injection molding, as well as cutting and welding / riveting.

Title: Method and composition for treating immune complex associated disorders
Inventor: RIFKIN IAN
IPC: G01N33/50
Filed: 2002-09-09
Abstract: The present invention provides methods and compositions for treating immune complex associated diseases (ICAD), such as SLE, rheumatoid arthritis, and hepatitis-C related immune complex disease (e.g., cryoglobulinemia) in a subject having an ICAD or at risk for developing ICAD. The invention is based upon the surprising finding that chromatin-containing immune complexes activate autoreactive B cells and dendritic cells by a dual receptor engagement process which, in both cell types, involves a Toll-like receptor (TLR). The methods of treating ICAD comprise administering a compound to an individual in need thereof that either 1) inhibits formation of the immune complex either by preventing formation and/or binding to the TLR, or 2) interferes with binding of an autoantigen-containing immune complex (or the antigenic component thereof) to the TLR, or 3) inhibits signaling pathways initiated by dual engagement of BCR and TLR (in B cells) or FcR and TLR (in dendritic cells) via immune complexed or uncomplexed autoantigens.

Patent CA-2472337-A1 (CA)
Title: Connection error detection and response
Inventor: JOHNSTON TODD
IPC: H01R13/64
Filed: 2003-08-05
Abstract: In an electrical apparatus wherein electrical devices are interconnected by coupling connectors and a desired interconnection of devices is achieved by an intended interconnection of mating components of coupling connectors, identification elements in one mating component of each connector produce identification signals representing identity of the mating component. Decoding means responsive to the identification signals produce an error signal representing an interconnection of connector components differing from the intended interconnection and, means responsive to the error signal effects a response when the actual interconnection of components differs from the intended interconnection of components. Responses are, advantageously, activation of an error indicator, inhibition of application of power to affected devices, or, with program controlled systems, display of a text error message, facilitation of user intervention for error correction, or automated re-programming to overcome interconnection errors.

Abstract: A method of increasing the efficiency of a fuel gas turbine by cooling combustion air. A first step involves providing a heat exchanger having a first fluid path and a second fluid path, such that a heat exchange takes place between fluids passing along the first fluid path and fluids passing along the second fluid path. A second step involves lowering fuel gas pressure to match fuel inlet pressure requirements for the fuel gas turbine, with the lowering in pressure resulting in a lowering in temperature of the fuel gas. A third step involves directing low temperature fuel gas through the first fluid path of the heat exchanger and combustion air through the second fluid path of the heat exchanger, such that a heat exchange takes place that raises the temperature of the fuel gas and. lowers the temperature of the combustion air.

Abstract: The invention concerns compositions and methods for the diagnosis and treatment of neoplastic cell growth and proliferation in mammals, including humans. The invention is based upon the identification of genes that are amplified in the genome of tumor cells. Such gene amplification is expected to be associated with the overexpression of the gene product as compared to normal cells of the same tissue type and contribute to tumorigenesis.  Accordingly the proteins encoded by the amplified genes are believed to be useful targets for the diagnosis and/or treatment (including prevention) of certain cancers, and may act as predictors of the prognosis of tumor treatment. The present invention is directed to novel polypeptides and to nucleic acid molecules encoding those polypeptides. Also provided herein are vectors and host cells comprising those nucleic acid sequences, chimeric polypeptide molecules comprising the polypeptides of the present invention fused to heterologous polypeptide sequences, antibodies which bind to the polypeptides of the present invention and to methods for producing the polypeptides of the present invention.

Title: Multiple-axis control system for an optical switch
Inventor: GHANDI KAMYAR
IPC: H04Q11/00
Filed: 2003-03-18
Abstract: A free space optical switch that uses open and closed loop control mode. The open loop control mode is used to transition to a state where light is sense d at a destination port. A closed loop control mode is then used, whereby a series of controlled dither signals (75) are adjusted for system dynamics. Modifying the dither signals (75) allows moving actuators at a rate that is much closer to the natural frequency of the underlying system, and speeds up the system convergence process. Variable modulation amplitudes may be employ ed on the dither signals (75) to maximize convergence speed. In particular, changes in the dither signal can be made in accordance with the change in amplitude as a function of a gradient along a parabola that models the optic al system response. The dither signals (75) may be compensated for a desired an d selectable attenuation level of output optical power.

Title: Method and stimulating oil and gas wells using deformable proppants
Inventor: MAHARIDGE RUSSELL L
IPC: E21B43/267
Filed: 2005-02-22
Abstract: A method of fracturing using deformable proppants minimizes proppant pa ck damage, without compromising the fracturing fluid's proppant transport properties during pumping, by use of deformable proppants. Selection of proppant is dependent upon the mechanical properties of the formation rock. The strength of the deformable proppant is dependent upon the modulus of the formation rock being treated such that the proppant is capable of providing, at the very least, a minimum level of conductivity in in- situ stress environments. The maximum elastic modulus of the deformable proppant is less than the minimum modulus of the formation rock which is being treated. The method is particularly applicable in fracturing operations of subterranean reservoirs such as those comprised primarily of coal, chalk, limestone, dolomite, shale, siltstone, diatomite, etc.
