Patent CA-2112234-C (CA)
Inventor: FRANK GEORGE A
IPC: D04H1/54
Filed: 1993-03-31
Granted: 1999-03-23
Abstract: A moldable, nonwoven composite material and method of manufacture thereof is provided. The method of manufacture includes by blending a mix of first fibers and second thermoplastic fibers. The second fibers have a melting point lower than that of the first fibers and comprise approximately 40-80 percent of the blend. The blend is then processed into a fibrous batt. The batt is then consolidated into a nonwoven structure with the first fibers being thoroughly intermixed with the second fibers. The nonwoven structure is then heated to a temperature below the melting point of the first fibers and above the melting point of the second thermoplastic fibers to substantially liquefy the second fibers and form a thermoplastic resin. The heated nonwoven structure is compressed to flow the liquefied resin to displace air voids in the nonwoven structure and encapsulate the first fibers. Finally, the nonwoven structure is cooled to form a composite material having substantially reduced air voids therein with the first fibers thoroughly encapsulated by the resin and with the composite material being substantially free from shrinkage when subjected to thermoforming.

Title: Hydrogel wound dressing product
Inventor: CARTMELL JAMES VERNON
IPC: A61L15/58
Filed: 1994-03-22
Granted: 1997-05-27
Abstract: A flexible wound dressing product (10) includes a thin-film layer (14), an adhesive layer (24), a backing layer (26) which may be porous, an optional support layer (34), an optional release liner (46), and a hydrogel material (42).

Abstract: A rotary disk valve has a valve body provided with an annular valve seat section defining a central opening to be removably closed by a valve disk. The valve disk is supported by a drive assembly which includes a drive shaft mounted on the valve body and supporting a drive link for rotation with the shaft. The link mounts a valve disk support shaft which extends slidably through a slot in a bracket secured to the valve disk. The bracket mounts a guide cam follower pin arranged to engage a guide cam secured to the valve body. The arrangement of drive shaft, valve disk support shaft, bracket slot and guide cam and follower is such that rotation of the drive shaft through 180° in one direction first moves the valve disk from open position disposed in a plane substantially perpendicular to the plane of the central opening in the valve body to an intermediate position spaced from but parallel to the valve seat surface, and then moves the valve disk linearly into sealing engagement with the valve seat section of the valve body. Reverse rotation of the drive shaft moves the valve disk from open to closed position.

Abstract: The present invention is directed to a method for treating waste water.  In order to reduce releasing of neutral salts comprising monovalent ions contained in industrial waste effluent to the environment, the waste effluent to be treated is supplied into a prepositive electrodialysis cell comprising ion exchange membranes which transfer monovalent ions selectively for concentrating the salts, the concentrated stream is supplied into an electrolytic dialysis cell for separating and recovering acids and bases, the subsequently diluted stream is circulated as supplying stream to the prepositive electrodialysis cell, the diluted stream in said prepositive electrodialysis cell is subsequently supplied to and desalted by one or more electro-dialysis cells combined in series, the diluted stream after the desalination is released to the environment, and the concentrated stream is merged to the supplying stream to the prepositive electrodialysis cell.  In accordance with the present invention, the concentration of impurities in the recovered acid decreases to less than 1/10, and necessary electric power for dialysis treatment and recovery of the acid and the base decreases to less than 1/2.

Abstract: The present invention relates to a protective brace for use by a figure skater to prevent impact borne bone bruising resulting from one or more falls of the skater on the ice.  The brace of the invention comprises a semi-rigid,  resilient plastic shell.   The latter has a generally rectangular web defining a longitudinal axis and having two downwardly oriented, wide, curved extensions at the respective extremities of the longitudinal axis.  The shell has  a  lower and an upper tongue  integrally and orthogonally  extending  from  the middle  of  the  web respectively downwardly and upwardly.  The shell is molded to fit a particular skater, the web resting on the lombo-sacral area of the back of the skater and molded so as to position the longitudinal axis partially around the hips, the two curved extensions projecting downwardly from the hips over the thighs, the lower tongue straddling over the coccygeal  section  of  the  spine  and  the  upper  tongue extending over the lombo-thoracic section of the spine. The brace further comprises ten straps that are attached to the  shell  and  that  are  destined  to  steadfastly  and removably secure the shell adjustably to the body of the skater.   The shell is of such a shape that it does not surround significantly any body articulation,  so as to allow a relatively good freedom of movement to the skater wearing the brace.  Indeed, the only part of the brace that surrounds the articulations  is the  light,  uncumbersome straps.

Title: Secure spread spectrum watermarking for multimedia data
Inventor: COX INGEMAR J
IPC: H04N7/52
Filed: 1996-09-06
Granted: 2000-05-30
Abstract: Digital watermarking of audio, image, video or multimedia data is achieved by inserting the watermark into the perceptually significant components of a decomposition of the data in a manner so as to be visually imperceptible. In a preferred method, a frequency spectral image of the data, preferably a Fourier transform of the data, is obtained. A watermark is inserted into perceptually significant components of the frequency spectral image. The resultant watermarked spectral image is subjected to an inverse transform to produce watermarked data. The watermark is extracted from watermarked data by first comparing the watermarked data with the original data to obtain an extracted watermark. Then, the original watermark, original data and the extracted watermark are compared to generate a watermark which is analyzed for authenticity of the watermark.
