Patent CA-2200373-C (CA)
Title: Heteroligand
Inventor: BROWN STEPHEN JOHN
IPC: C08F10/02
Filed: 1997-03-19
Granted: 2005-11-15
Abstract: A new family of metallacycles, which are preferably zirconacycles, is characterized by having a unique halogenated substituent. The metallacycles are useful for the preparation of main group heterocycles, especially two novel families of heterocycles. The first new family of heterocycles preferably contains a halosilyl substituent. A preferred group of the second family of novel heterocycles contains a silyl group having a leaving group bonded thereto. The preferred group of these heterocycles is suitable for preparing novel organometallic complexes having a bridged bidentate heterocyclic ligand. These novel organometallic complexes may be used as catalyst components in olefin polymerization. The subject catalyst components are particularly well suited for use in the medium pressure solution process to prepare linear low density polyethylene.

Granted: 2004-01-20
Abstract: A flameless heater (10) includes two non-woven polyester sheets (12, 14) which are thermally bonded along respective edges (16, 18, 20) and parallel weld lines (22, 24, 26) to form a number of pockets (28, 30, 32, 34). Each pocket is filled with a powder mixture of Mg-Fe alloy, NaCl, antifoaming agents, and an inert filler. The outer surfaces of the polyester sheets are preferably treated with a food grade surfactant. The polyester sheets are gas and water permeable over substantially their entire surfaces and the filled pockets define intervening channels (29, 31, 33, 29a, 31a, 33a) where the polyester sheets are bonded. Both the channels and the permeability of the sheets allow water to wet the powder rapidly and initiate the chemical reactions quickly. The byproducts of the chemical reactions exit the pockets through the permeable sheets and are directed away from the reaction via the channels.

Title: Erythrocytes loaded with s-nitrosothiol and uses therefor
Inventor: STAMLER JONATHAN S
IPC: A61K47/48
Filed: 1996-09-13
Granted: 2011-01-04
Abstract: Nitric oxide (NO) interacts with hemoglobin (Hb) at its metal centers, whereas S-nitrosothiols (RSNOs) can donate the NO group to .beta.93 cysteine residues, thereby shielding the NO functionality from heme inactivation. S-nitrosylation of Hb is under the allosteric control of oxygen and the oxidation state of heme. NO group release from SNO-Hb is further facilitated by intracellular low molecular weight thiols, forming RSNOs which can be exported from the erythrocyte to regulate blood pressure. Red blood cells can be loaded with low molecular weight RSNOs to act as a delivery system for NO+ groups. Loaded red blood cells can be used in methods of therapy for conditions which are characterized by abnormal O2 metabolism of tissues, oxygen-related toxicity, abnormal vascular tone, abnormal red blood cell adhesion, or abnormal O2 delivery by red blood cells.

Title: Materials having high electrical conductivity at room temperatures and methods for making same
Inventor: GRIGOROV LEONID N
IPC: C08F2/46
Filed: 1997-01-31
Granted: 2008-04-29
Abstract: A method is disclosed for producing a polymer material whose room temperatur e conductivity exceeds 10 6 S/cm. In a preferred embodiment the material is produced in the form of a film having thickness less than 100 .mu.m. Conduction takes place through threads passing through the film which is otherwise a dielectric. The film is produc ed by first depositing a macromolecular polymer substance on a substrate. During preparation, the substance must be in a viscose liquid state. Stable free electrons (polarons) are then created by ionizing the substance. This is assisted by exposure to UV radiation and the presence of strong polar groups in the polymer. Various techniques, such as applying a strong electric field, are then used to join the polarons together into conducting threads within the medium. To stabilize the conductivity, the medium is then solidified by cooling it below its glassing point or inducing cross-linking between the macromolecules.

Granted: 2001-11-27
Abstract: A modular building panel and a method for constructing the same provides a framework composed of structural members, typically formed of metal, and a backer board typically formed of a cementacious composite for receiving an exterior wall coating surface. The backer board and the framework are separated from, and insulated from, each other by a layer of foam that is applied in liquid form and that expands and cures into a solid form. Substantially no fasteners extend between the backer board and the metal framework to reduce conduction of heat therebetween. The foam serves as an adhesive to hold the backer board rigidly in place at a predetermined spacing from the framework and to anchor the backer board to the structural members. The structural members can comprise U-shaped and C-shaped channel beams for further rigidity and enhanced anchoring. Upon assembly, the backer board and the framework are overlaid upon each other, typically using spacers of a predetermined spacing thickness.  Spacers can be formed from pieces of foam having adhesive or double-sided tape to maintain them in alignment with the framework and backer board. Liquid foam is applied from the interior side of the framework and expands toward the interior side of the framework.
