Patent CA-2122747-A1 (CA)
Inventor: WEISS VICTOR H
IPC: H01M50/124
Filed: 1994-05-03
Abstract: Disclosed is a method for preparing and attaching a battery test label to a battery. More particularly the battery is at least partially encased with a non-conductive film having a top surface and bottom surface and a conductive circuit layer is disposed on at least a portion of the bottom surface and extends such that a first area is disposed over a first battery terminal and a second area is disposed over a second battery terminal. A non-conductive material is disposed over a portion of the conductive circuit layer so that at least a portion of the first and second areas disposed over the first terminal and second terminal, respectively, are not covered by the non-conductive material so that the first area can be deflected to contact the first terminal and the second area can be deflected to contact the second terminal of the battery with the remainder of the conductive circuit layer being electrically and thermally insulated from the terminals of the battery by the non-conductive material. A thermally sensitive material is disposed in responsive contact with the conductive circuit layer such that when the first area and second area of the conductive circuit layer contact the first terminal and second terminal, respectively, a current will flow through the conductive circuit layer and heat the thermally sensitive material which will indicate whether the battery has any capacity.

IPC: D04H1/58
Filed: 1994-09-29
Abstract: A tri-dimensional non-woven fabric particularly well-suited for use as a skin-contacting cover layer of a sanitary absorbent product such as a sanitary napkin, a diaper, a urinary pad, an adult brief, a wound dressing, or a nursing pad, among others.  The non-woven fabric is characterized by a pattern of elongated and alternating high and low fiber density areas.  Such structure has the ability of  directing a discharge  of  body exudate to disperse over the surface of the non-woven fabric in a preferential direction.  The non-woven fabric also has the ability of dynamically inducing body exudate to migrate through the low fiber density areas when the fibrous network  is  subjected to repeated bending or twisting movements.   The invention also extends to a method for manufacturing the aforesaid non-woven fabric and to a sanitary article utilizing same.   The invention further extends to a sanitary absorbent article utilizing a novel skin-contacting  cover  layer  capable  to  establish  and maintain an  intimate  liquid-communicative relationship with an absorbent core of the sanitary absorbent article without any adhesive.

Inventor: HEIBER WERNER E
IPC: A61M35/00
Filed: 1993-05-03
Abstract: A transdermal/transmucosal drug delivery system utilizes glycerin to moderate the initial burst effect of transdermal drug delivery and also maintain the delivery to the derma/mucosa at a relatively sustained rate over the duration of the application to either an application or afflicted situs. The drug composition contains an effective amount of a percutaneously absorbable drug and an amount of glycerin which is effective to moderate and maintain the transdermal delivery of the drug. The system also-contains means for maintaining the drug composition in a drug transferring relationship with the derma/mucosa. When applied to an afflicted situs the composition is preferably a gel, cream, lotion or ointment. When applied to an application situs the compositions are contained within a device such as a matrix or liquid reservoir patch which is held to the application site by means of the adhesive. The drug composition may contain glycerin in amounts of between about 0.1 to 50 % by volume.

Patent CA-2142193-A1 (CA)
Title: Methods and apparatus for high-shear material treatment
Inventor: HOLL RICHARD A
IPC: B02C19/18
Filed: 1993-08-24
Abstract: High-shear treated materials are passed through a high-shear treatment zone which allows the coexistence of free supra-Kolmogoroff eddies larger than the smallest possible Kolmogoroff eddy diameter and forced sub-Kolmogoroff eddies smaller than this diameter. This zone includes a subsidiary higher-shear zone for suppressing these free eddies. The passage walls (40, 44, 102, 108) move relative io one another transverse to the flow to force the simultaneous development of supra-Kolmogoroff and sub-Kolmogoroff eddies while maintaining liquid films adherent to the passage surfaces. The movement produces only forced sub-Kolmogoroff eddies in the susidiary zone while maintaining a non-turbulent flow. Ultrasonic oscillations (52) may be appli-ed to cause elastohydrodynamic pressure and viscosity increases and/or production of smaller sub-Kolmogoroff eddies. One ap-paratus includes an inner cylinder rotatable (46) inside a hollow outer cylinder (38), another consists of two circular coaxial plates, and the rotational axis can be vertical or horizontal.

Title: Servo-writing system for use in a data recording disk drive
Inventor: BEST JOHN STEWART
IPC: G11B21/08
Filed: 1995-03-10
Abstract: A non-invasive servo-write system for use in a data recording disk drive. The system measures actuator position and generates a reference clock using semiconductor lasers. Internal position references are provided by reflective diffraction gratings affixed to the actuator arm and the spindle hub. Wavefront reconstruction optics correct for aberrations in the gratings. Optical sensors detect differential changes in the diffraction patterns created by the gratings, eliminating sensitivity to frequency drift. Decode electronics convert optical sensor data into an actuator position measurement. Control electronics drive the voice coil motor within the disk drive, which positions the write transducer to record servo information provided in a servo pattern generator. Transparent windows in the head-disk-assembly cover allow the servo-writer to write drives which are completely assembled and sealed.

Patent CA-2146342-A1 (CA)
Inventor: MAGGARD STEVEN M
IPC: G01N21/65
Filed: 1992-10-07
Abstract: A calibrated spectrometer can indirectly determine a physical or chemical property of a sample based upon spectral re-sponses measured by the spectrometer with respect to the particular sample. This invention is directed to a method for calibrating or recalibrating a second spectrometer in light of a first spectrometer, or itself, respectively. The calibration employs a unique se-lection and manipulation of spectral data obtained from both the first and the second instrument. The recalibration employs a un-ique selection and manipulation of spectral data from the same first instrument, that is obtained both before and after the need for recalibration arises. Instead of modifiying the respective responses of the first and second instrument, or the first instrument before and after the need for calibration arises, this invention modifies the calibration equation of the second, or recalibrated in-strument, to yield consistent results to those obtained by the first instrument, or the first instrument before it goes out of calibra-tion. A calibration equation is an equation which transforms spectral data of a particular sample at a variety of wavelengths to a calculated value for a chemical or physical property. Generally, the form of such calibration equations is that of a linear combina-tion of absorbances or mathematical transforms of absorbances measured by the first and second instrument for each sample. Surprisingly, and confirmed statistically, the accuracy of the calibrated or recalibrated instrument is maintained and in some in-stances improved.
