Title: Improved mordant and method of dyeing fibers
Inventor: GURLEY SALLY
IPC: D06P1/34
Filed: 1994-05-05
Abstract: An improved mordant solution and process for preparing fibers for dyeing and fixing natural dyes to fibers, particularly but not exclusively cellulose fibers, including cotton and linen, and synthetic fibers, including Rayon? and TenselTM. The improved natural mordant solution comprises an aqueous solution of alum KA1(SO4) and soda ash Na2CO3, most preferably an aqueous colloidal suspension of aluminum hydroxide. This mordant solution significantly improves the recognized qualities of naturally dyed fibers, including light and washfastness, without using polluting heavy metal mordants. The improved mordant treatment and natural dye process includes first pretreating the fabric with an aqueous mordant wash, which increases the dye uptake in the dye bath, then treating the fabric with a second aqueous mordant wash, following dyeing, then preferably treating the dyed fabric with a final tannin wash, permanently setting the natural dye in the fibers or fabric.

Patent CA-2171616-A1 (CA)
Title: Stable hygroscopic detergent article
Inventor: HEILE BERNARD JOSEPH
IPC: C11D7/14
Filed: 1994-12-20
Abstract: The invention provides an environmentally stable detergent article. Normally, hygroscoptic caustic detergent materials can be made resistant to absorption of ambient humidity or water by introducing a barrier coating onto the caustic detergent. The barrier also renders the highly active alkaline material safe for human handling. The coated detergent article can further be enclosed in a film enclosure or wrapping which provides further protection for handling during production, shipment, storage and final end use. The coated article can be removed from any parkaging material, inserted into a water spray-on dispenser and used to create a concentrated aqueous detergent for use in ware washing machines. In order to obtain control over dispensing, hydrophobic coatings can be nicked, split, peeled or partially removed using other means to provide an initial surface of caustic detergent exposed to the water spray. The water spray can then dispense the detergent and either melt or dissolve the hydrophobic coating in a controlled manner.
Patent CA-2174491-A1 (CA)
Title: Automated feature detection and identification in digital point-ordered signals
Inventor: OPPENLANDER JANE E
IPC: G06F17/00
Filed: 1996-04-18
Abstract: A computer-based automated method to detect and identify features in digital point-ordered signals. The method is used for processing of non-destructive test signals, such as eddy current signals obtained from calibration standards. The signals are first automatically processed to remove noise and to determine a baseline.  Next, features are detected in the signals using mathematical morphology filters. Finally, verification of the features is made using an expert system of pattern recognition methods and geometric criteria. The method has the advantage that standard features can be located without prior knowledge of the number or sequence of the features. Further advantages are that standard features can be differentiated from irrelevant signal features such as noise, and detected features are automatically verified by parameters extracted from the signals. The method proceeds fully automatically without initial operator set-up and without subjective operator feature judgement.
Patent CA-2175636-A1 (CA)
Inventor: MARK JOHN G
IPC: G01C19/72
Filed: 1996-05-02
Abstract: A loop controller for a fiber optic gyroscope employs distributed data processing to compress numerous additional useful functions into each loop transit time.  The architecture of the loop controller includes a field programmable gate array for generating variables of varying sign.  In addition, the array acts to buffer the transmission of parameters between the gyro processor and an auxiliary processor.  The auxiliary processor updates such parameters (which do not require updating every loop transit time) and a number of such parameters are multiplied by values generated by the array in operations performed by the gyro processor that replace what would otherwise require throughput intensive test and branch operations.  The combination of the off-loading of selected variable and parameter generation and updating with programming of the gyro processor for parallel processing permits the loop controller to perform numerous useful operations not previously possible during a realistic loop transit time.

Abstract: Procédé de mise en couleur de morceaux de roche, à savoir de marbre, par application d'un faisceau laser (2) permettant de conférer une couleur à tout ou partie du morceau de roche. Le faisceau laser coopère avec le morceau de roche (5) auquel on applique ensuite un colorant approprié. La diffusion du pigment dans le morceau de roche en modifie la couleur dans la zone touchée par le laser. Le morceau de roche revêt une couleur ayant l'intensité voulue. Par conséquent, on peut valoriser du marbre de valeur inférieure, et valoriser et colorer d'autres roches. Ce procédé est destiné principalement au traitement des roches décoratives.

Title: Foot egress chair bed
Inventor: FOSTER L DALE
IPC: A61G7/012
Filed: 1995-01-25
Abstract: A hospital bed (10) that is convertible to a chair for patient egress from the foot end of the bed. A patient support platform (18) has se-rially hinged, normally hor-izontal head (28), seat (30), thigh (32) and foot (34) pan-els. To convert the horizon-tal bed to the chair configura-tion, the patient support plat-form (18) in the lowermost vertical position is translated longitudinally toward the foot end of the bed (10). The head panel (28) is pivoted upwardly and the foot panel (34) piv-ots downwardly to a gener-ally vertical attitude. The foot panel (34) includes a collaps-ing portion (46) which tele-scopes into a pivoting portion (44) to thereby avoid interfer-ence with the floor as the foot panel (34) is pivoted to a verti-cal attitude. When converted to the chair configuration, an area is vacated at the foot end of the bed to provide a space for docking a wheelchair or other ambulatory assisting device. The patient's feet rest directly on the floor in the chair configuration in that the foot panel collapses into itself as it pivots downwardly rather than pivoting along a second axis to underlie the patient's feet.

Inventor: TAYLOR JOHN W
IPC: B65H23/04
Filed: 1996-11-14
Abstract: There is disclosed a web of record members of the composite label web,  tag and linerless types with cracks or fissures through the webs so that the position of the web can be detected by an optical detector.  Apparatus can be used to convert the web into more usable form which includes for provision of optically detectable cracks or fissures in the web.  These cracks are made by crushing the web locally between one or more crushing cutters and a back-up roll which cooperates with zero clearance.  The method and apparatus can produce a reliably detectable web at low cost.   The optical detector includes a source of light and a bicell detector between which the web with the cracks or fissures passes.   The bicell detector produces a first output signal representing the amount of light impinging on a first portion of the detector and a second output signal representing the amount of light impinging on a second portion of the detector.   A difference circuit is coupled to the bicell detector to provide a signal representing the difference between the first and second output signals of the bicell detector.   From this difference signal the leading and trailing edges of a crack or fissure can be detected.
