Patent CA-2352104-C (CA)
Title: Invertible emulsions stabilised by amphiphilic polymers and application to bore fluids
Inventor: MONFREUX NATHALIE
IPC: C08F8/32
Filed: 1998-11-23
Granted: 2010-11-16
Abstract: The present invention relates to polyelectrolytes which have been modified so as to be rendered hydrophobic by amidification of a hydrophilic backbone using n--alkylamines, the alkyl chains of which contain 6 to 22 carbon atoms. Amidification is preferably carried out using di-n-dodecylamine. The hydrophilic backbone is preferably a sodium polyacrylate or the corresponding polyacrylic acid or an acrylate-AMPS statistical copolymer. The polymers of the invention can be used to stabilize direct or reverse emulsions which are prone to being destabilized or reversed by modifying the degree of salinity of the aqueous phase or by modifying the pH.   The invention is of particular application to petroleum or analogous drilling fluids, in particular drilling, fracturing, acidizing or completion fluids.

Abstract: A method and apparatus for providing lateral support to a post includes a cage-like structure comprised of one or more modular cage units which are installed about the post. A plurality of guy wires are attached to the cage-like structure and anchored to the floor, ground, or the like, for providing lateral support to the post. Each cage unit includes a pair of main components with each main component including a pair of elongate generally parallel bar members. A lower connection bracket is attached to the bottom of each main component and includes a bolt hole for connecting the main component to a loading fame or other cage units. An upper connection bracket is attached to the top of each main component, and includes a bolt hole for connecting one main component to another main component placed on top thereof. The upper bracket also includes a pair of rod holes located near the free ends of the upper bracket for attaching a pivotable guy wire attachment fixture between two main components. The guy wires are attached to the attachment fixture and anchored to the ground for providing lateral support to the cage-like structure, and thereby to the post. A number of cage units may be stacked, one-upon-the-other to construct a cage-like structure of any desired height to provide lateral support to posts of various heights. In addition, the cage-like structure does not inhibit the upward extension of the post.

Title: .beta.-turn peptidomimetic cyclic compounds
Inventor: BURGESS KEVIN
IPC: A61K31/38
Filed: 2001-01-18
Granted: 2010-06-08
Abstract: Proteolytically stable small molecule .beta.-turn peptidomimetic compounds have been identified as agonists or antagonists of neurotrophin receptors, such as TrkA. A compound of particular interest binds the immunoglobulin-like C2 region of the extracellular domain of TrkA, competes the binding of another TrkA ligand, affords selective trophic protection to TrkA-expressing cell lines and neuronal primary cultures, and induces the differentiation of primary neuronal cultures. The small .beta.-turn peptidomimetic compounds of the invention can activate a tyrosine kinase neurotrophin receptor that normally binds a relatively large protein ligand. Such compounds that bind the extracellular domain of Trk receptors are useful pharmacological agents to address disorders where Trk receptors play a role, by targeting populations selectively.

Abstract: L'invention concerne un sac de conservation doté d'une ouverture refermable, laquelle est sollicitée pour que soit obtenue une configuration ouverte. Le sac, généralement constitué d'un matériau thermoplastique tel qu'un polyéthylène à faible densité, comprend des première et seconde couches adjacentes, raccordées ou pliées le long des côtés inférieurs et latéraux. Les côtés supérieurs ne sont pas pliés ou raccordés de manière permanente, mais sont dotés d'éléments de fermeture tels que des bandes mâle et femelle correspondantes. Le sac comprend également une structure permettant d'écarter les côtés supérieurs l'un de l'autre, ce qui sollicite l'ouverture du sac pour lui faire adopter une configuration ouverte. Les éléments de fermeture sont assez solides pour résister à la force de la structure d'écartement, si bien qu'ils peuvent maintenir le sac fermé lorsque les éléments de fermeture sont engagés l'un dans l'autre. Toutefois, lors de la séparation des éléments de fermeture, la structure d'écartement écarte les côtés supérieurs du sac pour conférer à ce dernier une configuration d'ouverture ouverte.

Abstract: Cette invention se rapporte à un pistolet à clouer (1), qui comprend un canon (23) et un mécanisme de chargement (20) servant au chargement des clous (3) du magasin (19) jusque dans la bouche (14) du canon. Les clous (3) sont conçus pour être propulsés par un poinçon (16) via une navette à piston (7) se déplaçant sous l'action d'un gaz propulseur, lequel est initialement stocké sous forme liquide dans un réservoir (2). Le liquide est chauffé à une température supercritique dans une chambre sous haute pression (4) par un élément chauffant (5) afin d'induire un changement de phase transformant le liquide en un gaz très dense. Ce changement de phase transformant le liquide en gaz produit l'énergie requise pour propulser le clou (3) de la bouche (14) du canon, quelque soit la température ambiante. Le gaz propulseur est de préférence du CO¿2? chauffé à 31,06· C. Un sélecteur de pression (9) permet différents réglages de pression pour le bois tendre, le bois dur et la maçonnerie. Ce pistolet (1) produit un minimum de bruit et réduit ainsi les nuisances sonores sur le lieu de travail.

Abstract: An iron type golf club head includes a body having a front face arranged for impact with a golf ball, a back face, a heel portion and toe portion. A hosel is connected to the heel portion of the body. A perimeter weighting element protrudes rearwardly from the front face and defines a primary cavity in the back face of the body. The perimeter weighting element includes a top rail and a sole which extend between the body heel and toe portions along an upper portion and a lower portion, respectively, of the body. An interior wall extends from a first end connected to the perimeter weighting element adjacent the body heel portion through the primary cavity- between the top rail and the sole to a second end connected to the perimeter weighting element adjacent the body toe portion to define an elongated secondary cavity or tuning port within the primary cavity. The interior wall is integrally formed on a bottom surface of the primary cavity and extends from the bottom surface of the primary cavity in a direction that is substantially perpendicular to the longitudinal axis of the hosel. This orientation of the interior wall provides the secondary cavity, i.e. the tuning port, with a low profile while also moving the center of gravity of the club head lower and farther away from the front face.
