Title: Rna-dependent rna polymerase functioning preferably on rna matrix and promoter-dependent transcription process with said rna-dependent rna polymerase

Abstract: Disclosed is a process for transcribing RNA using a nucleotide reagent as the promoter. Such a reagent enables any type of RNA to be transcribed without sequence specification and without protein cofactors, by means of an RNA polymerase that is known to be DNA-dependent such as the RNA polymerase of the phage T7, or by means of new, mutated RNA polymerase with the ability to synthesize a transcription product of a polynucleotide matrix with a higher yield when the matrix is RNA than when said matrix is DNA. This type of RNA polymerase can be obtained by effecting mutations on a coding gene for a wild-type RNA polymerase, and then by selecting the mutated RNA polymerase with said ability. The invention can be applied notably to the detection, synthesis or quantification of RNA.

Abstract: A wavelength selective resonant grating exhibits transmission resonances when a single gap between two sections of a split gratings is used to provide a phase shift which is not a quarter wavelength in length or .pi./2 in phase. When the phase is changed to non -.pi./2 values (or the gap differs from a quarter wave), the transmission resonance moves from the center of the stop band. Appropriate adjustments of the phase over a .pi. interval allow tuning of the resonance across the entire stop band. The resonant optical wavelength grating can, illustratively, be used as wavelength filter, wavelength monitor, or as part of an Add/Drop arrangement.

Patent CA-2315132-C (CA)

Granted: 2004-07-27
Abstract: A method for fabricating adherent, patterned carbon nanotube films is provided. According to the invention, a substrate is patterned with a carbide-forming material, a carbon-dissolving material, or a low melting point metal. Carbon nanotubes are then deposited onto the patterned substrate, but have relatively poor adhesion to either the substrate material or the patterned material. The substrate is then annealed, typically in vacuum, at a temperature dependent on the particular patterning material, e.g., a temperature at which carbide formation occurs, at which carbon dissolution occurs, or at which the low melting point metal melts. The annealing thereby provides an adherent nanotube film over the patterned areas, while the nanotubes deposited onto the non-patterned areas are easily removed, e.g., by blowing, rubbing, brushing and/or ultrasonication in a solvent such as methanol.

Abstract: The present invention relates to a method for making a vehicle frame member having a shock absorbing mounting portion constructed and arranged to be mounted to a structural component within a motor vehicle. The method comprises hydroforming a tubular blank within a hydroforming die by supplying pressurized fluid to the hollow interior of the blank. A drawforming member is moved inwardly with respect to the cavity of the hydroforming die while the fluid is pressurized so that the drawforming member deforms a portion of the tubular wall inwardly to form a recessed portion having an annular side wall portion and a bottom wall portion. The formed tabular blank is then removed from the hydroforming die and a mounting structure (38) is disposed inside the recessed portion and the blank and mounting structure (38) are then disposed within an injection molding die. Molten shock absorbing material (14) is injected into the recessed portion so that the molten material (14) surrounds the mounting structure. The molten shock absorbing material is thereafter solidified. Preferably, a pair of such recessed portions are formed. The present invention also relates to a vehicle frame member to be joined to a structural component in shock absorbing relation.

Abstract: A cylinder head for an engine having a two-plane water jacket in which a lower chamber at one plane through the head cools the fire deck of each cylinder and a cross-flow passage for the coolant is spaced above the lower chambers in a second plane through the head directs coolant to an outlet. The two planes of the water jacket are connected by an annular passage surrounding the injector nozzle sleeve and has machined surfaces whereby the size of the flow channel and thus the coolant flow between the two planes is better controlled to enable more even cooling of the fire deck resulting in less variability in fire deck temperature from one cylinder to one another. The lower chambers cooling the fire deck are separate for each cylinder to prevent heated coolant from one cylinder flowing to the next cylinder fire deck.

Title: Reversible driven pulley
Inventor: CHAMBERLAND RENE
IPC: F16H63/06
Filed: 1999-04-16
Granted: 2003-10-07
Abstract: The driven pulley (10) is used in a continuously variable transmission (CVT).  It comprises a main shaft (12), a fixed flange (14) and a movable flange (16).  The first cam system comprises a cam plate (22), provided with cam surfaces (24), and corresponding cam followers (28). The second cam system also comprises a cam plate (40), provided with cam surfaces (42), and corresponding cam followers (46). During a normal forward rotation of the driven pulley (10), corresponding to a forward motion of a vehicle, the first cam system is automatically disabled and the position of the movable flange (16) is governed by the second cam system. However, under motor-braking conditions, the first cam system takes over the control and the second cam system is disabled.  Similarly, the first cam system governs the position of the movable flange (16) during a normal reverse rotation of the driven pulley (10) and the second cam system takes over the control under motor-braking conditions as the vehicle is traveling rearwards.

Granted: 2004-04-27
Abstract: A synchronizing apparatus for a differential OFDM receiver that simultaneously adjust the radio frequency and sample clock frequency using a voltage controlled crystal oscillator to generate a common reference frequency. Timing errors are found by constellation rotation. Subcarrier signals are weighted by using complex multiplication to find the phase differentials and then the timing errors.      The reference oscillator is adjusted using the timing errors. Slow frequency drift may be compensated using an integral of the timing error. Frequency offset is found using the time required for the timing offset to drift from one value to another.

Title: Document management method and tool
Inventor: BAGLEY MARK
IPC: G06F17/22
Filed: 2000-02-16
Granted: 2008-01-29
Abstract: A method and tool for the management of documents stored in a computer file system is provided. Such management is performed through the application of templates to the documents, each template being effective, when applied to a document, to carry out a pre-determined operation on the document. Typically, at the present day, the association of templates with documents is achieved through the inclusion of instructions within the documents. These instructions will then require re-editing when the template is to be changed. In contrast the invention associates templates with directories. The method and tool are effective to apply the one or more templates associated with a given directory to content files stored within that directory to produce templated versions of the content files. Should the template applied in the templated file be required to be changed however, instead of having to re-edit the templated file, the changed template may be associated with the directory in which the content file is stored and the method-re-excuted through re-running of the tool. Alternatively, the content file could be moved to a directory in which the changed template is already associated and the method re-executed through the re-running of the tool. A particularly advantageous application tothe creation and management of Web sites is disclosed.

Granted: 2009-11-24
Abstract: This patent describes a method and system which overcomes the LO-leakage problem of direct conversion and similar RF transmitters and receivers.  To solve this problem a virtual LO.TM.  signal is generated which emulates mixing with a local oscillator (LO) signal.  However, the virtual local oscillator (VLO) signal is constructed using signals that do not contain a significant amount of power (or no power at all) at the wanted output RF frequency, so there is no LO component to leak to the output.  The invention also does not require sophisticated filters or large capacitors as other designs in the art, so it is fully integratable.
