Patent CA-2286343-A1 (CA)
Title: Rna-dependent rna polymerase functioning preferably on rna matrix and promoter-dependent transcription process with said rna-dependent rna polymerase
Inventor: ORIOL GUY
IPC: C12Q1/6865
Filed: 1998-03-27
Abstract: RNA may be transcribed using a nucleotide reagent as the promoter. The reagent may enable 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 polynucleotide matrix with a higher yield when the matrix is RNA than when the 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 the ability. The invention can be applied notably to the detection, synthesis or quantification of RNA.

Title: Linear power control loop
Inventor: LOFSTAD ERIC W
IPC: H03L7/18
Filed: 2000-02-17
Abstract: The present invention presents a closed loop system that utilizes a non-linear reference to control a power amplifier's output power in order to obtain a linear transfer function of dB per adjustment step of a reference input. The closed loop system demonstrates that each non-linear stage/step in an automatic gain control system can create a linear closed loop system when using a non-linear reference. The closed loop system of the present invention eliminates the need for a linearization circuit for the system's power detector. The closed loop system may be used with most power amplifiers when linear control in terms of dB vs. adjustment setting of the input reference signal is desired. Output power in terms of dBms can be accurately set in linear steps where power control over a wide dynamic range is desired.

Filed: 2000-02-23
Abstract: An apparatus and method for cleanly breaking a continuously advancing cellulose web is disclosed. The apparatus includes a transfer fabric which supports and advances the cellulose web to a wind up zone. The transfer fabric forms a closed loop and is driven at a desired speed by a drive roll. At least two spray nozzles are arranged transversely across the advancing cellulose web as it is carried on the transfer fabric.  The spray nozzles are capable of emitting a liquid under high pressure against the advancing cellulose web to form perforations across the width thereof. A plurality of hollow cores are independently and sequentially moved into position at the wind up zone to receive the advancing cellulose web. The hollow cores are located downstream of the spray nozzles and each hollow core is capable of accumulating a predetermined amount of the cellulose web. The apparatus further includes controls for activating the spray nozzles in timed sequence to the speed of the transfer fabric such that a predetermined amount of cellulose web can be accumulated on each hollow core to form a finished roll having a predetermined diameter. An assembly is also present for moving each of the finished rolls away from the advancing cellulose web while simultaneously moving a second hollow core into contact with the advancing cellulose web upstream of the finished roll. The contact by the second hollow core and the employment of vacuum increases the tension on the advancing cellulose web and causes the advancing cellulose web to cleanly break at the perforations and form a leading edge. A vacuum is then applied to the second hollow core which causes the leading edge of the advancing cellulose web to wrap onto it. The method encompasses the sequential steps required to break the advancing cellulose web using the above-identified apparatus.

Title: Single point diamond turning lathe with vibration cancelling feature
Inventor: MCPHERSON EDWARD ARTHUR
IPC: B24B41/00
Filed: 2000-07-13
Abstract: A method and apparatus for substantially nullifying vibration and deflection in a single point lens turning lathe having a rapidly reciprocating lens cutting tool and shuttle assembly. The apparatus includes three or more tool shuttles of similar mass mounted for reciprocating movement along respective generally parallel shuttle paths. The shuttles are reciprocally moveable by respective actuators along their respective shuttle paths. The shuttle and tool assemblies are moved by their respective actuators in opposite directions at a rate which causes forces generated by shuttle and tool assemblies moving in one direction to cancel forces arising from the shuttle and tool assembly movement in the opposite direction. Should an odd number of shuttle and tool assemblies be used, the amount of force generated by the mass moving in one direction may be compensated by having a different rate of movement, and hence a different stroke length from the mass moving in the opposite direction.

Title: Incident analysis and solution system
Inventor: PARADIES MARK W
IPC: G06Q10/10
Filed: 2000-10-11
Abstract: A computer-implemented system determines, by logical progression through multiple analysis levels, a human factor that represents a root cause of a particular incident. The system begins at a broad analysis level and progresses through more narrow analysis levels to a root cause level. Each analysis level includes multiple causal factor categories, with each causal factor category branching into causal factor subcategories that reside on a more narrow analysis level. The system includes an information input device for inputting incident information relating to the particular incident. The system also includes a memory device for storing a causal information database that provides a relationship between the multiple analysis levels and causal factor categories and between causal factor categories and root causes. The causal information database also relates root causes to corrective actions that may be implemented to prevent future occurrences of the incidents. A processor accesses the causal information database and determines a human factor that represents a root cause of the particular incident. This determination is made by logical progression through the multiple analysis levels based upon the incident information from the information input device. The processor logically progresses through the multiple analysis levels by selecting, based upon the incident information, an appropriate causal factor category at each analysis level. The processor accesses the causal information database and determines at least one corrective action that may be implemented to prevent future occurrences of the particular incident based on the root cause of the particular incident. The system further includes a display device for displaying a graphic representation indicating the causal factor categories selected by the processor in determining the root cause of the particular incident. The display device also displays the corrective actions that may be implemented to prevent future occurrences of the particular incident.
