Patent CA-2336572-A1 (CA)
Title: Method and apparatus for a coriolis flowmeter having its flow calibration factor independent of material density
Inventor: LANHAM GREGORY TREAT
IPC: G01F1/84
Filed: 1999-05-28
Abstract: A single tube Coriolis flowmeter of enhanced flow sensitivity in which material flow induces Coriolis deflections in a flow tube and Coriolis-like deflections in a balance bar vibrationally coupled to the flow tube. Both the Coriolis deflections and the Coriolis-like deflections have a phase shift determined by material flow and are used co-adjuvantly to derive material flow information. The flowmeter achieves a constant flow sensitivity over a range of changes in material density by 1) varying the flow sensitivity in a first direction under control of the ratio between the drive mode vibration amplitude of the flow tube and the balance bar and 2) varying the flow sensitivity in an opposite direction under control of the ratio between the Coriolis deflection amplitude of the flow tube and the Coriolis-like deflection of the balance bar. The drive mode vibration amplitude ratio varies with changes in drive mode frequency caused by changes in material density.  The amplitude ratio of the Coriolis deflection and the Coriolis-like deflection changes with changes in the magnitude of the separation of the drive mode frequency and the second bending mode frequency to the balance bar density which, in turn, is caused by changes in material density.

Title: Method for operating pollution-free engine expansion chamber and expansion chamber therefor
Inventor: NEGRE GUY
IPC: F01B17/02
Filed: 1998-07-09
Abstract: The invention concerns a method for operating a pollution-free engine chamber by injecting supplementary compressed air, comprising a suction and compression chamber (1) and an expansion and exhaust chamber (4) independent of each other, which consists in separating the pressure increase process in said expansion chamber by dividing it into the two chambers, an engine chamber (2A) which receives high pressure air and a working chamber (2B) which receives the supplementary compressed air with lower pressure, separated by a quick-operating plug (2c) which communicates them suddenly thereby causing, owing to difference in pressure levels, a wave expanding the engine gas which flows into the working chamber generating a compressive shock wave substantially increasing the pressure level in the chamber shortly before it is communicated with the expansion and exhaust cylinder (4) to produce a work.

Title: Modified polymers having controlled transmission rates
Inventor: HEKAL IHAB M
IPC: B01J20/28
Filed: 1999-05-25
Abstract: The present invention includes processes and resulting structures for producing a modified polymer having channels. The channels act as controlled transmission passages through the polymer. A polymer (25) is caused to assume a molten state, typically by applying heat and melting the polymer. A channeling agent (35) is blended then reacted into the polymer so that it is distributed within the polymer. In one embodiment, an absorbtion additive (30) is blended into the product so that the additive forms passages (45) in the product through which a desired compound is communicable to the additive that is entrained within the product. The solidified product may be used to form a desired shaped article such as plug type inserts (55) and liners (70) for closed containers (60), or it may be formed into a film, sheet (75), bead, or pellet.

Title: Method of determining radioactive nuclides
Inventor: UEZU YASUHIRO
IPC: G21C17/00
Filed: 2001-06-04
Abstract: A method of simply and quickly determining .alpha.-ray releasing nuclides having long half-life without carrying out a chemical separation is provided. By inputting a data of pulses incident to an .alpha.-ray detector in a computer, obtaining time distribution of the incident pulses by using a very short time measuring timer and plotting, and fitting the linear originated in a random event corresponding to the background and the non-linear originated in the correlated events of parent nuclides- progenies by using the least squares method, the whole generating probability P (t) from the parent nuclide to the progeny thereof is obtained. By subtracting the random events portion from the P(t), the correlated events portion is extracted. The radioactivity per unit can be obtained by dividing the extracted correlated events portion by the measured time, the amount of the supplied sample and the counting efficiency. Also, by determining nuclides unnecessary for the measurement by this method and removing the determined nuclides from the energy spectra of objective nuclides to thereby lower the background, the objective nuclides can be determined by using pulse-height discrimination.

IPC: H01M10/04
Filed: 2002-02-14
Abstract: The present invention relates to a current collector for an electrochemical cell. The current collector has a unique grid structure comprised of a frame supporting a plurality of radial strands as conductors radiating outwardly from a focal point on a connector tab. The frame and radial conductors are maintained in a fan-like orientation with respect to each other by two groups of concentric conductor strands, one located adjacent to the tab, the other spaced a substantial distance therefrom. The radiating conductors provide a more direct path to the connector tab for electron flow. This results in the current collector having reduced internal resistance in comparison to conventional current collector designs.

Title: Electrical surface activated downhole circulating sub
Inventor: ESTEP JAMES W
IPC: E21B34/06
Filed: 2000-08-17
Abstract: A preferred novel circulating sub (300) includes an electric motor (310), hydraulic intensifier, connecting rod (360), valve sleeve (370), valve plug (375), and angled nozzles (430). Upon activation of the circulating sub (300) the electric motor (310) drives the valve sleeve (370) over the valve plug (375), causing a flow of drilling fluid to exit the angled nozzles (430). Upon deactivation of the circulating sub (300) the electric motor (310) removes the valve sleeve (370) from the valve plug (375), allowing the flow of drilling fluid to once again flow to the drill bit (125). Because the electric motor (310) is reversible, the circulating sub (300) can be repeatedly activated and deactivated.
