Patent CA-2105632-C (CA)
Inventor: PILAND CLINTON E
IPC: A47J43/08
Filed: 1993-09-07
Granted: 1998-04-21
Abstract: A blender is provided with a microprocessor for controlling energization of the blender drive motor, and a plurality of manually actuated switches for controlling the stepping of the microprocessor through a program which determines the mode and pattern of energization of the drive motor.  There are N speed range selection switches, M speed selection switches and a pulse mode switch.  Depending on the sequence in which these switches are actuated, the microprocessor controls the drive motor in a manual continuous mode at any one of N x M speeds, a manual pulse mode at any one of N x M speeds or an autopulse mode with any one of three patterns of energization.          In the first pattern of energization the motor is energized to run at one of M constant speeds during intervals T1 which are separated by intervals T2 during which the motor is not energized.  In a second pattern of energization the motor starts at one of M speeds, the energization being gradually decreased over each interval T1 so that the motor speed decreases.  In a third pattern of energization, the motor is initially energized to run at one of M speeds with the energization increasing over each interval T1.  Any mode may be programmed for one of M run intervals.  All modes and patterns of motor energization are controlled by only M + N + 1 switches (excluding ON/OFF switches) and the sequence in which the switches are actuated.

Title: Process for the production of permeation resistant containers
Inventor: GARG DIWAKAR
IPC: C08J7/00
Filed: 1993-11-29
Granted: 1997-12-16
Abstract: Plastic containers with excellent resistance to permeation by solvents are prepared by a multi-step treatment of the plastic containers in a controlled manner with fluorine containing gases while blow molding them. In the process of the present invention, a parison is formed from a pre-heated thermoplastic material, expanded within a closed mold by means of an inflating gas for conforming the parison to the shape of the mold, and subjected to at least two fluorination treatment steps to effect fluorination of the interior surface of the parison. In the initial fluorination step the parison is pressurized with a reactive gas containing no more than 1% fluorine by volume while the parison is at a temperature above its self supporting temperature and for a time sufficient to effect initial fluorination of the interior surface of the parison. Subsequently, the interior surface of the pre-fluorinated parison is pressurized with a reactive gas containing fluorine in a concentration that is greater than that used in the initial fluorination step. Preferably, molecular oxygen contaminant in the parison is eliminated or minimized prior to and during fluorination.

Title: Screening assay for the detection of dna-binding molecules
Inventor: EDWARDS CYNTHIA A
IPC: C12Q1/68
Filed: 1992-06-26
Granted: 1996-08-06
Abstract: The present invention defines an assay use-ful for screening libraries of synthetic or biological compounds for their ability to bind specific DNA test sequences. The assay is also useful for deter-mining the sequence specificity and relative DNA-binding affinity of DNA-binding molecules for any particular DNA sequence. The assay is a competition assay in which binding of a test mole-cule to a DNA test sequence changes the binding characteristics of a DNA-binding protein to its binding sequence. When such a test molecule binds the test sequence the equilibrium of the DNA:protein complexes is disturbed, generating changes in the ratio between unbound DNA and DNA:protein complexes. The assay is versatile in that any test sequence can be tested by placing the test sequence adjacent to a defined protein binding DNA screening sequence.

Title: Process for the obtention of biological adhesive made of concentrated coagulation factors by salting-out
Inventor: BUI-KHAC TRUNG
IPC: C12N9/10
Filed: 1994-01-18
Granted: 2000-05-16
Abstract: The present invention relates to a process of making a concentrate of coagulation proteins starting with whole human or animal plasma. This concentrate is used as a biological adhesive when extemporaneously mixed to thrombin. The concentrated proteins include mostly fibrinogen, fibrin stabilizing factor (factor XIII) and fibronectin. The claimed process has the advantage of being short of execution while providing an excellent yield of coagulable protein. No protease inhibitor has to be added during the process. The process involves steps of separation by "salting-out" in presence of amino-6 hexanoic acid which prevents co-precipitation of plasminogen with the desired coagulable proteins. The proteins so obtained are very stable after reconstitution in water for at least 24 hours at room or body temperature. After mixing with thrombin and calcium, the adhesive shows excellent strength and biocompatibility.

Abstract: An optical rotation device (10) with infinite depth of field for transmitting optical images along an optical axis and selec-tively rotating the image (26) about the optical axis, while preserving all of the three dimensional characteristics of the image. The optical rotation device consists of two optical elements (12,14) optically coupled in series, each of which produces an inversion of the image about an axis orthogonal to the optical axis. Rotation of the image by any angle in the plane normal to the optical axis is achieved by rotating the two optical elements relative to one another about the optical axis.

Title: Resonant circuit and multiple resonator circuits constructed therefrom
Inventor: BROWN ANTHONY KEVIN DALE
IPC: H03B27/00
Filed: 1992-12-09
Granted: 1996-05-14
Abstract: A resonant circuit comprises first (600) and second (600') amplifiers.  An input of the second amplifier is coupled to an out-put of the first amplifier, and an output of the second amplifier is cross-coupled to an input of the first amplifier. The first ampli-fier has a first gain and a 90 degree phase shift between its input and its output at a resonant frequency of the resonant circuit. The second amplifier has a second gain and a 90 degree phase shift between its input and its output at the resonant frequency of the resonant circuit.  The second gain is different from the first gain.  The resonant circuit can have a first port (Ap, An) and sec-ond ports (Bp, Bn) coupled to an input and an output respectively of one of the first and second amplifiers.  Because the gains of the first and second amplifiers differ, the gain from the first port to the second port of the resonant circuit will dif-fer from the gain from the second port to the first port.  This gain difference is useful for enhancing the quality factor Q of multiple resonator circuits constructed from such resonant circuits.

Title: Method and apparatus for producing a porosity log of a subsurface formation
Inventor: ALLEN LINUS SCOTT
IPC: G01V5/10
Filed: 1993-08-09
Granted: 2002-03-12
Abstract: A borehole logging tool (10) is lowered into a borehole tra-versing a subsurface formation and a neutron detector (19) mea-sures the die-away of nuclear radiation in the formation. Intensity signals are produced representing the die-away of nuclear radiation as the logging tool (10) traverses the borehole. A signal processor (17), employing as least one neural network, processes the intensity signals and produces a standoff corrected epithermal neutron life-time signal to correct for standoff from the borehole wall (24) en-countered by the detector (19) as the logging tool (10) traverses the borehole. The signal processor further generates a porosity signal from the standoff corrected epithermal neutron lifetime signal de-rived from measurements in borehole models at known porosities and conditions of detector (19) standoff. A log is generated of such porosity signal versus depth as the logging tool (10) traverses the borehole.

Abstract: The present invention relates to methods and systems for reducing pollutant emissions associated with combustion operations, e.g. cement manufacturing.  The invention further relates to the disposal of sludge, e.g., produced by waste water treatment plants, by introducing it into the combustion process.  In particular, the invention provides for introducing particles of aqueous sludge into a kiln at a point in the kiln effective to reduce pollutant emissions in outlet flue gasses produced by the kiln. Optimally, the sludge is introduced at a point in which maximum NOx emission rductions can occur and maximum HC1 emission reductions can occur downstream (at lower temperatures).  In a specific embodiment, introduction of about 10 to about 20 tons per hour of wet sludge results in about a 15 % to 30 % reduction in NOx emissions in a cement kiln.
