Title: Core pipe based magnetic sensing system for adjusting tension in rolls of winding sheet material
Inventor: ETOU NAOMICHI
IPC: B65B43/04
Filed: 1997-08-29
Abstract: It is desired to prevent disalignment of the edges of a folded sheet by smoothly feeding the sheet while keeping tension fluctuactions to a minimum when the sheet is unwound from a paper roll set in a paper feed unit to a packaging unit even though the paper roll diameter decreases gradually as the sheet is unwound. A sheet length measuring sensor or rotary encoder is provided in the paper feed path through which the packaging sheet unwound from the paper roll is fed toward the packaging unit. An angle sensor is provided which comprises Hall element sensors provide on a support shaft and magnets provided on a core pipe of the paper roll. Any change is the signals from one of these sensors relative to the signal from the other sensor is used to calculate the paper roll winding length, and the sheet tension is adjusted to an optimum, constant level by controlling the sheet braking force stepwise according to the roll diameter measured by the sensors.

Patent CA-2317749-A1 (CA)
Inventor: NARIMAN KHUSHRAV ERACH
IPC: B01J20/28
Filed: 1999-01-06
Abstract: This invention is directed to a process for the conversion of hydrogen sulfide into sulfur by contacting the hydrogen sulfide feed gas with a sulfated sorbent, such as sulfated magnesium aluminate spinel. The improvement involves combusting a portion of the hydrogen sulfide containing feed gas in a preburner so as to convert hydrogen sulfide into sulfur dioxide; introducing this sulfur dioxide into the hydrogen sulfide feed via a conduit, and contacting the resulting mixture of hydrogen sulfide feed gas and sulfur dioxide with a sulfated sorbent. Thus, much of the oxygen required for oxidizing the hydrogen sulfide into elemental sulfur comes from the sulfur dioxide produced from this combustion of a portion of the feed hydrogen sulfide, rather than from the oxidized/sulfated solid sorbent. This decreases the amount of sorbent required and the frequency of sorbent regenerations.

Title: Sonophoretic enhanced transdermal transport
Inventor: KOST JOSEPH
IPC: A61M37/00
Filed: 1999-01-08
Abstract: Methods for enhanced transdermal transport wherein the application of ultrasound is required only once for repeated or sustained transdermal extraction or delivery, over a period of time, rather than prior to each extraction or delivery. The method is applicable to analyte extraction, as well as for drug delivery. The method involves the initial application of an amount of low frequency ultrasound effective to permeabilize the skin or membrane followed by analyte extraction or drug delivery over a period of time. The initial application of ultrasound is effective to permeabilize the skin or membrane for at least about 30 minutes, preferably at least one to two hours, and more preferably up to four to ten hours. The ultrasound is preferably low frequency ultrasound, less than 2.5 MHz, more preferably less than 1 MHz. The transdermal transport can be enhanced by the application of a secondary driving force such as suction, osmotic pressure gradient, concentration gradient, iontophoresis, electroporation, magnetic field, additional ultrasound, or mechanical pressure.

Patent CA-2331493-A1 (CA)
Inventor: WENTZ BRENDA D
IPC: B32B38/16
Filed: 2000-01-31
Abstract: The invention relates to a method of promoting the adhesion of textiles to rubber compounds through a vinyl compound plasma pre-treatment procedure and a subsequent aplication of resorcinal-formaldehyde latex (RFL) to the textile surface. The inventive method encompasses a process through which free radicals of compounds comprising strong carbon-carbon bonds form a film over textile films and then covalently bonded to the resin component of the RFL. Such a method thus produces an extremely strong and versatile adhesive that facilitates adhesion between rubber compounds and heretofore unusable or difficult-to-use textiles. The resultant textile/rubber composites are utilized as reinforcements within such materials as automobile tires, fan belts, conveyor belts, and the like. Such materials and composites are also contemplated within this invention.

Abstract: Procédé permettant de déterminer des températures (tqm, tqh, tom, tok) dans un transformateur à bain d'huile, selon lequel sont mesurées les tensions (2) au niveau des bornes du transformateur, les courants (3) dans les bobinages et la température ambiante (6). En outre est relevé le statut (5) d'aérateurs et de pompes et la position (4) d'un commutateur de prises de réglage. Les valeurs mesurées et relevées (2, 3, 4, 5, 6) sont introduites dans un modèle (7) thermohydraulique dans lequel sont calculées des grandeurs d'état (19) à l'aide de valeurs auxiliaires (9) qui représentent les pertes (10) dans le transformateur, les paramètres (1) de transfert de chaleur, les résistances (13) à l'écoulement et l'écoulement (12) d'huile, et d'un réseau hydraulique du circuit d'huile qui présente des ramifications et des noeuds. Lesdites grandeurs d'état (19) sont les températures moyennes (tqm) et les températures (tqh) aux points chauds dans les parties du transformateur produisant des pertes et les températures moyennes de l'huile dans les ramifications (tom) et dans les noeuds (tok) du réseau hydraulique du circuit d'huile. En cas de modification des valeurs mesurées et relevées (2, 3, 4, 5, 6), les valeurs auxiliaires (9) sont adaptées en conséquence, puis la vitesse de modification des grandeurs d'état (19) est déterminée, ce qui permet le calcul de nouvelles grandeurs d'état (19). Ce procédé permet de déterminer des températures (tqm, tqh, tom, tok), ainsi que leur modification au sein du transformateur, sans capteur de température, ce qui garantit un fonctionnement optimal du transformateur, et permet d'identifier de manière précoce les défaillances et les dangers et de déterminer le moment optimal pour les travaux d'entretien.
