Patent CA-2284943-A1 (CA)
Inventor: MAGARD-HANSEN OVE
IPC: F16G11/00
Filed: 1999-10-04
Abstract: A wire lock for interlocking two lengths of wire (8, 9) which intersect each other in mutual contact, said wire lock comprising a U-shaped part (1) for receiving one length of wire (8), and a top member (2) intended to be received in the U-shaped part on top of the length of wire therein. One end of the top member has a curve shape (6) intended to be positioned on top of the other length of wire (9), when this is positioned against the U-shaped part, as well as a locking element (3) to be placed in an opening (10) in the legs of the U-shaped part for clamping the top member and the underlying first length of wire in the U-shaped part, whereby the top member simultaneously claims the second length of wire against the first one with its curve-shaped part for interlocking these lengths. The curve-shaped part of the top member continues in two legs (7) which extend down on each side of the first length of wire, preferably a length greater than the radius of the wire. The wire lock provides a high degree of certainty that the intersecting length of wire does not unintentionally slide out of the lock.

Title: Ion sensitive binder for fibrous materials
Inventor: MUMICK PAVNEET SINGH
IPC: D04H1/64
Filed: 1998-05-09
Abstract: A water soluble polymer binder for binding a fibrous substrate comprises from about 25 weight percent to about 85 weight percent of an unsaturated carboxylic acid/unsaturated carboxylic acid ester terpolymer; from about 5 weight percent to about 35 weight percent of a divalent ion inhibitor; and from about 10 weight percent to about 60 weight percent of a hydrophilic crosslinkable polymer. In a preferred mode of the invention the hydrophilic crosslinkable polymer functions substantially as a divalent ion inhibitor and promotes hydrophilicity of the treated fabric eliminating the requirement of a separate divalent ion inhibitor. The binder composition is soluble in an aqueous environment having a divalent ion concentration less than about 50 ppm and a monovalent ion concentration of less than about 0.4 weight percent. Also disclosed is a water dispersible fibrous fabric having an effective amount of the binder distributed on the fibrous substrate and a method of making a water dispersible fibrous fabric.

Abstract: Dans la présente invention, on divulgue une méthode pour inhiber l'adhérence de bactéries à une surface submersible. Pour cette méthode, on met en contact la surface submersible avec une quantité efficace d'au moins un acide sulfamique ou un de ses sels, de manière à inhiber l'adhérence bactérienne à ladite surface. Dans la présente invention, on divulgue également une méthode qui permet de contrôler l'encrassement biologique d'un système aqueux. Pour cette procédé, on ajoute une quantité efficace d'au moins un acide sulfamique ou un de ses sels pour inhiber l'adhérence de bactéries à une surface submergée dans ledit système aqueux. Cette méthode permet de contrôler efficacement l'encrassement biologique pratiquement sans tuer les organismes salissants. L'acide sulfamique utilisé pour la méthode de la présente invention a la formule R1R2NS(O)2(OH). Dans cette formule, R1 et R2 sont indépendamment un atome d'hydrogène, un alkyle en C4-C20 ou un cyclohexyle. Toutefois R1 et R2 ne sont pas tous deux un atome d'hydrogène. R1 et R2 avec l'atome d'azote peuvent aussi former un hétérocycle à 5-8 atomes ayant la formule (I). Pour l'hétérocycle, X est un atome d'oxygène, NH ou CH2. Le sel de l'acide sulfamique peut être un sel acide ou un sel quaternaire. Dans la présente invention, on divulgue également une composition contenant des acides sulfamiques ou des sels de ceux-ci pouvant être utilisés pour les méthodes susmentionnées.

IPC: F16L37/091
Filed: 2000-03-15
Abstract: A push fit connector (400) for use as an attachment to connect two pipes (100,101) has two connecting portions (10,11) at opposite sides of an inwardly deformed ridge (2) in outer tubular metal body (302) having inwardly deformed lips (8,8') at each end around a respective entrance opening to the corresponding connecting portion (10,11). The connecting portions are similarly arranged and substantially symmetrically disposed with respect to the ridge. Connecting portion (11) has an annular abutment element (3'), an elastomeric sealing ring (308), an annular intermediate abutment (310), a grab ring (312) with inwardly directed teeth in a frusto-conical array, an outer bush (314) and a sleeve (316) axially slidable in the bush (314). When the sleeve (316) is pushed inwardly of the connecting portion (11) a wedge-shaped annular head or lip on the sleeve acts on the teeth of the grab ring (312) to displace them radially outwards so they can disengage from the pipe (101) thus releasing it so that it can be pulled out of the connector (400). Dotted line C demarcates an end of the envelope of the attachment (400). Teeth releasing movement by the sleeve (316) can only begin to occur once end face (342) on a free end of the sleeve is substantially flush with end C of the envelope or is actually wholly within the envelope. End face (342) faces outwardly from the body (302).

Filed: 1998-02-06
Abstract: A system and method for managing behavioral health care data includes an electronically governed transfer of selected information between patient databases residing at a provider site and a host site. The system and method eliminate human intervention at the host site in select cases in which treatment approval is sought and can be granted electronically on the basis of a set of rules resident in the host site computer based upon patient coverage.  Treatment outcome can also be uploaded at predetermined intervals, and, if deemed necessary by the provider, an extension of the approved treatment can be sought and granted, again without human intervention at the host site in select cases. An automatic download of patient information to a provider site selected on the basis of such criteria as area of specialization and geographical location can be initiated from the host site.
