Patent CA-2181304-C (CA)
Inventor: BEAUDIN LAURENT
IPC: E21B47/00
Filed: 1996-07-16
Granted: 2001-10-16
Abstract: A method for detecting changes in the rate of discharge of fluid from a well bore. Firstly, providing a flow nipple having a first end, a second end, and a flow line connection extending substantially radially from the flow nipple intermediate the first end and the second end. Secondly, providing a drilling fluid treatment tank. Thirdly, providing a flow line having a first end and a second end. The first end is connected to the flow line connection of the flow nipple and the second end to the drilling fluid treatment tank. This creates a flow path for drilling fluids from the flow nipple along the flow line to the drilling fluid treatment tank. Fourthly, providing an elongate antechamber adjoining one of the flow nipple, the flow line or the drilling fluid treatment tank. The elongate antechamber has a first end and a second end. The first end is positioned in fluid communication with the flow path. The second end extends above the flow path, such that the second end of the elongate antechamber is free of drilling fluid unless a sudden increase in flow rate results in an influx of drilling fluid into the elongate antechamber. Fifthly, positioning a fluid sensing probe in the elongate antechamber. The fluid sensing probe is spaced from and extends toward the first end of the elongate antechamber, such that the fluid sensing probe provides a reading of the level of drilling fluid in the elongate antechamber.

Title: Meltprocessible starch composition, a process for the preparation thereof and the use of the composition
Inventor: VUORENPAA JANI
IPC: C08B31/04
Filed: 1996-07-10
Granted: 2008-05-20
Abstract: The invention concerns a biodegradable starch composition, a process for the preparation thereof, the use of the composition and a process for increasing the degradation rate of intermediate products manufactured from starch derivatives and/or products made therefrom under conditions of biodegradation. According to the invention the composition contains 5 to 99 wt-% of a plastisized starch derivative and 1 to 95 wt-% of a biodegradable fibrous material. The microstructure of the composition is discontinuous and formed by a phase containing the starch derivate and a phase containing the fibrous material and any porosity, and its impact strength is at least 10 % better than the corresponding values of a plastisized starch derivative. The composition may further contain 0.01 to 30 wt.% of a biodegradable polyester, such as polylactide, polycaprolactone or a cellulose ester. According to the invention, the biodegradable starch composition is prepared by esterification of starch with glycerol in order to form a mixture containing starch acetate and acetic acid and then the mixture is blended with a biodegradable fibrous material for producing a composition which has a discontinuous microstructure. The invention provides a melt processible composition having good water resistance and mechanical properties which can be regulated by changing the relative amounts and the qualities of the components of the composition.

Title: System and method for measuring acoustic reflectance
Inventor: KEEFE DOUGLAS H
IPC: G01H15/00
Filed: 1996-12-06
Granted: 2008-04-22
Abstract: A system for testing the auditory response of the human ear by measuring the linear and nonlinear power-based responses thereof uses a small probe assembly (50) containing a sound source (24, 52, 54) and microphone (30, 52, 56) inserted into the ear. The linear responses, or transfer functions, include reflectance, admittance and impedance. A calibration procedure is based upon measured pressure responses in one or more calibration waveguides (60), and upon a model of th e transfer function of each of the calibration waveguides. The nonlinear responses are established by measuring the above transfer functions at different levels of the acoustic stimulus. By delivering changes in static pressure applied to the ear via an additional probe tube (68, 70) in the probe assembly (50), the system is able to measure the dependence on static pressure of any of these linear and nonlinear power - based functions.
