Inventor: WEYHRAUCH ERNEST C
IPC: H05B37/00
Filed: 2005-12-07
Abstract: A method of converting a line voltage to an RMS load voltage in a lamp includes performing fixed forward phase-control clipping of a load voltage with a phase-control clipping circuit that provides an RMS load voltage to the lamp and providing pulses at constant time intervals from a time-based pulse source. conduction in a three-terminal thyristor in the phase-control clipping circuit is triggered with the pulses from the time-based pulse source independently of the line voltage magnitude, wherein periods of conduction in the three-terminal thyristor define a conduction angle of the phase-control clipping circuit.

Inventor: HILAIRE PIERRE
IPC: A61F2/06
Filed: 2004-10-14
Abstract: A catheter system and method are described for stenting a vessel at a bifurcation or sidebranch of the vessel. The catheter system includes a first balloon catheter, a second balloon catheter and a releasable linking device for holding the first and second balloon catheters arranged in a side-by-side configuration and aligned with one another along a longitudinal axis. The linking device allows the catheter system to be advanced as a unit and helps prevent premature or inadvertent dislodgement of the stent from the catheters, yet is releasable so that one or both of the balloon catheters can be released from the linking device and maneuvered separately from the rest of the catheter system when desired. The method utilizes the described catheter system for stenting bifurcated vessels using a modified "kissing balloons"  technique.

Patent CA-2550259-A1 (CA)
Inventor: NEFF ANDREW C
IPC: H04L9/28
Filed: 2001-03-24
Abstract: A cryptographic process permits one to verifiably shuffle a series of input data elements. One or more authorities or individuals "shuffle", or "anonymize" the input data (e.g. public keys in discrete log form or ElGamal encrypted ballot data). The process includes a validity construction that prevents any one or more of the authorities or individuals from making any changes to the original data without being discovered by anyone auditing a resulting proof transcript. The shuffling may be performed at various times.  In the election example, the shuffling may be performed, e.g., after ballots are collected or during the registration, or ballot request phase of the election, thereby anonymizing the identities of the voters.

Title: Electron beam tubes
Inventor: BARDELL STEPHEN
IPC: H01J5/08
Filed: 2005-02-22
Abstract: A linear electron beam tube comprises an electron gun having a cathode and a grid, and an anode arranged in a first portion of a drift tube. The drift tube is within a vacuum envelope and has first and second portions separated by a gap at which point an electron beam, density modulated with an input RF signal is inductively coupled to an output cavity. The vacuum envelope is partially defined by a cylindrical ceramic wall and a pair of ferromagnetic pole pieces at its ends that form a DC magnetic circuit. The pole pieces extend radially beyond the vacuum envelope. At least those parts of the surface of the pole pieces that are in the RF path are coated with a layer of relatively low RF loss material such as copper. A balance ring separates the ceramic from the pole pieces. Further reduction in RF losses and relief from thermal stresses is obtained by forming the balance ring from the same ceramic as the cylindrical wall and metallizing at least that part of the outer surface of the balance ring that is on the RF path.

Patent CA-2582795-A1 (CA)
Inventor: NEWMAN FREDERIC M
IPC: E21B47/00
Filed: 2007-03-26
Abstract: An instrument, such as a wall-thickness, rod-wear, or pitting sensor, can monitor tubing as a field service crew extracts the tubing from an oil well or inserts the tubing into the well. A computer-based system can process data from the instrument to evaluate the validity of the data. Validating the data can comprise determining whether any features, structures, or patterns present in the data correlate with actual tubing defects or were caused by a condition unrelated to tubing quality, such as signal noise. The computer-based system can also analyze the data to deduce information about the performance of the well or to determine the well's operating state or status. For example, the data analysis can determine whether the well's fluids have a chemical condition that should be treated or whether a detrimental harmonic oscillation has been occurring in the well's mechanical pumping system.
Patent CA-2584234-A1 (CA)
Inventor: GRATTAN DAVID A
IPC: G05D9/00
Filed: 2005-10-21
Abstract: A method of providing a continuous, sequential, and cyclic, if desired, liquid feed to a processor from a plurality of containers, which comprises feeding the liquid from a first of the containers through a first conduit to a reservoir having a float valve, to keep the level of the liquid in the reservoir high enough to maintain the float valve in an upper floating position that closes the float valve. The first conduit is uncontrolled by the float valve. The float valve controls a second conduit which connects with a second container. As liquid is withdrawn from the reservoir for processing, liquid from the first conduit and container replenishes the reservoir until it is exhausted. Then, the liquid level drops, and the float valve opens the second conduit for replenishing the reservoir with liquid from the second container. A crossover valve may be used so that the float valve controls flow from either container connected to the second conduit.
