Patent CA-2331726-A1 (CA)
Inventor: GRIFFEY RICHARD
IPC: C12Q1/68
Filed: 1999-05-12
Abstract: Methods for the identification of compounds which modulate, either inhibit or stimulate, biomolecules are provided. Nucleic acids, especially RNAs are preferred substrates for such modulation. The present methods are particularly powerful in that they provide novel combinations of techniques which give rise to compounds, usually "small" organic compounds, which are highly potent modulators of RNA and other biomolecular activity. In accordance with preferred aspects of the invention, very large numbers of compounds may be tested essentially simultaneously to determine whether they are likely to interact with a molecular interaction site and modulate the activity of the biomolecule. Pharmaceuticals, veterinary drugs, agricultural chemicals, industrial chemicals, research chemicals and many other beneficial compounds may be identified in accordance with embodiments of this invention.

Abstract: L'invention concerne un procédé d'induction d'une nucléation dans un polymère consistant à soumettre le polymère contenant du gaz dissous à une contrainte extérieure produite, par exemple, par application d'une pression hydrostatique ou mécanique. La contrainte appliquée limite la croissance des bulles de manière que les matériaux moussés présentent des petites cellules et une haute densité de cellules. Ces mousses microcellulaires peuvent être produites sur une large gamme de basses températures, c'est-à-dire à partir de la température à laquelle le polymère est conditionné avec l'agent porogène jusqu'à environ la température de transition vitreuse du système polymère-agent porogène. La nucléation induite par contrainte peut aussi être exécutée à des températures plus élevées, c'est-à-dire allant jusqu'à environ la T¿g? du polymère pur, conduisant à la production de mousses à cellules plus grandes. Cette technique permet de produire une variété de mousses homogènes et hétérogènes.

IPC: A61F2/06
Filed: 1999-11-12
Abstract: An insoluble polymer is deposited in a body cavity for instance to embolise a vein or pack an aneurysm, the polymer having pendant zwitterionic groups to improve biocompatibility. The insoluble polymer is preferably formed by an in situ gelling step in which a charged, preferably soluble, polymer having pendant zwitterionic groups is introduced in the form of a composition in which it is soluble and is gelled by being mixed with a counterionically charged soluble polymer (polyelectrolyte), to form a polyion complex. Preferably the or each soluble polymer is formed by polymerising ethylenically unsatured monomers including a zwitterionic monomer, for instance 2-methacryloyloxyethyl-2'-trimethylammoniumethyl phosphate inner salt, an ionic monomer such as trimethylammonium alkyl(alk)acrylate or a sulphoalkyl(alk)acrylate and optionally a diluent monomer such as an alkyl(alk)acrylate.

Patent CA-2351286-A1 (CA)
Inventor: ROBERTS BRUCE WYNN
IPC: C23C8/02
Filed: 2001-06-21
Abstract: A steel blade for turbomachinery, for example a vane or blade of stainless steel for a steam turbine, has its working surface smoothed, for example by tumble polishing, to a smoothness of about 0.25 microns Ra or less. Then the smoothed surface is subjected to plasma nitriding to harden the surface to a value of, for example, about 1000 on the Vickers hardness scale. The hardened nitrided layer in the steel can be 25 to 100 microns thick. The plasma nitriding process does not affect the smoothness of the area of surface being nitrided, and the resultant surface hardness preserves smoothness of the surface while the blade is in use.

Title: Dolly having multiple supports hingedly joined together
Inventor: DEMKO CRAIG J
IPC: B62D61/10
Filed: 2001-07-11
Abstract: A dolly for transporting multiple containers. The dolly is provided with a plurality of casters which allow it to spin on its footprint. Supports, each of which can carry a container, are hinged together allowing the dolly to flex when encountering alterations in flooring level. Also provided are large side wheels which reduce the force necessary to push the dolly over a bump or onto a floor which is at a higher elevation.  When one support is not carrying a container, the support can be rotated with the hinge to a point at which it is approximately perpendicular to the adjacent support and thereby approximately vertical to the floor. Rotating one support to an approximately vertical position shortens the dolly footprint and aids in storage. Moreover, a support which is rotated to an approximately vertical position can be temporarily maintained in that position by a lock.
