Patent CA-2283911-A1 (CA)
Title: Absorbent articles comprising a material having a high vertical wicking capacity
Inventor: TAYLOR GREGORY WADE
IPC: A61F13/15
Filed: 1998-03-26
Abstract: Disclosed are absorbent cores for inclusion in articles such as diapers, incontinent briefs, training pants, diaper holders and liners, feminine hygiene garments, and the like, designed to provide improved fit and comfort for the wearer while adequately containing body exudates. The absorbent core is designed so as to retain low levels of fluid in the crotch region, relative to the other core regions, even when the core absorbs significant amounts of fluid during use. To achieve this, the absorbent core is designed such that fluid is moved substantially from the crotch region to the front and/or rear ends of the article. In particular, the absorbent core comprises in its crotch region a material having significant vertical wicking absorbent capacities.

Title: Structure alveolaire et procede pour realiser cette structure
Inventor: BARRON BRADFORD SCOTT
IPC: B31D3/02
Filed: 1998-04-20
Abstract: Procédé pour réaliser une structure alvéolaire. Ce procédé consiste à fendre de manière intermittente une feuille de matériau de manière à former des fentes longitudinales alignées pour constituer des rangées alternativement décalées. Chaque rangée décalée présente une ligne centrale latérale espacée de manière sensiblement uniforme des lignes centrales adjacentes. Les fentes longitudinales dans chaque rangée décalée présentent un espacement latéral sensiblement uniforme. L'opération suivante consiste à appliquer des bandes continues d'adhésif dans le sens latéral, entre le côté supérieur et le côté inférieur de la feuille de manière à espacer chaque bande dans le sens longitudinal et à la centrer sur une rangée de fentes. Ces bandes sont appliquées en alternance entre le bord supérieur et le bord inférieur. L'étape suivante consiste à plisser la feuille de manière à former des plis longitudinaux. Chaque pli comporte une pliure supérieure et une pliure inférieure alignées avec une fente longitudinale. Ensuite, les plis sont rassemblés en une pile fermée et comprimés de manière que les plis soient assemblés par les bandes adhésives en des points de contact adhésif. L'étape terminale consiste à écarter les plis en tirant latéralement pour former des alvéoles hexagonales présentant des interconnexions aux points de contact adhésif, et des ouvertures entre ces points d'adhérence.

Abstract: A regulator for a nurse inductor mechanism on an agricultural seeding implement controls the rate of entrainment of seeds into the stream of air directed into the nurse inductor mechanism. The regulator includes a pivoted gate mounted at the discharge opening of the seed reservoir of the nurse induction unit to control the flow of seed particles into a pile for engagement with the stream of air directed thereto. An actuation lever, positioned externally of the nurse inductor housing so as to not interfere with the sealed relationship between the divider walls of the distribution apparatus and the housing, is selectively manipulable to move the pivoted gate between closed and opened positions. Once the pivoted gate is moved into the closed position, the flow of seed particles into the distribution apparatus is halted, but the full flow of air can still move through the distribution apparatus and seed distribution tubes to effect a clean-out of the nurse induction unit.

Filed: 1999-11-25
Abstract: A full cone spray nozzle having a vane which comprises a plurality of vane segments each disposed in a respective quadrant of a vane chamber and formed with respective flat ramp surfaces and concave surfaces which divide the incoming liquid into two flow streams and impart vortical and turbulent movement to the liquid such that the liquid discharged from the nozzle has a conical spray pattern with liquid particles distributed throughout the spray pattern. The vane chamber is formed with outwardly extended recesses adjacent and across from concave surfaces of the vane segments for ensuring maximum free tangential passage of solids through the vane without affecting the liquid flow rate. In one embodiment the recesses are in the form of slots in a cylindrical mounting ring of the vane segments and in another embodiment the recesses are outwardly extending grooves in a cylindrical wall of the nozzle body which defines the vane chamber.

Abstract: Microwave equaliser with internal amplitude correction, preferably for application in satellite communications, comprising at least one resonant cavity (2), at least one incoming signal injection means (6) that projects into said resonant cavity (2) for injecting signal into said resonant cavity (2), and at least a first resistive tuning means (5). The position of said first tuning means (5) with respect to said input signal injection means (6) produces electromagnetic coupling between both means (5) and (6), giving rise to an amplitude attenuation effect in said signal. A variation in said relative position between said means permits changing said attenuation in a selective manner. A second resistive tuning means (7) can be used in combination with the first resistive tuning means (5) to optimise the response of the equaliser.

Title: Process for removing selenium from refinery process water and waste water streams
Inventor: OVERMAN STEVEN D
IPC: C02F1/52
Filed: 1998-10-15
Abstract: The present invention provides an efficient and highly effective method of removing dissolved selenium from a variety of refinery process water and wastewater streams. The present invention also provides a new and effective method of oxidizing selenium and organo-selenium compounds to the selenite ¢+IV! oxidation state in order to be adsorbed by a metal oxide or metal hydroxide precipitate. The invention includes two continuous stirred-tank reactors (CSTR) operated in series. The stream to be treated and one of several irons salts (ferric sulfate, ferric chloride, etc.) are introduced into the first CSTR, forming ferric hydroxide and ferric oxyhydroxide precipitates. The pH of the first CSTR is automatically controled by adjusting the injection rate of the ferric salt. The effluent stream from the first CSTR is directed into a second CSTR into which potassium permanganate is introduced. The selenium in the original stream to be treated is oxidized to selenite ¢+IV!; manganese dioxide precipitates as a byproduct of the oxidation reactions. The selenite is then adsorbed by the various precipitates, which are removed by centrifugation. The pH of the centrifuged water is automatically adjusted by the controlled addition of sodium hydroxide. The effectiveness of this continuous process has been demonstrated for streams with a wide range of selenium concentrations, including refinery wastewater and refinery stripped sour water. The process is also effective for treating secondary wastewater streams, such as reverse osmosis reject water and ion exchange regeneration wastewater, which result from the pretreatment of refinery wastewater or refinery stripped sour water.
