Patent CA-2361090-A1 (CA)
Inventor: WOZNICZKA BOGUSLAW
IPC: H01M8/02
Filed: 2001-11-02
Abstract: An encapsulating seal for an electrochemical cell stack provides sealing when individual cell seals fail and also provides increased insulation and protection for the stack and its components.      The encapsulating seal also provides compressive force to the stack, thereby reducing the need for a separate compression mechanism. The encapsulating seal is disposed on at least one side of the cell stack and at least between one or more pairs of separator plates having a membrane electrode assembly between them. An improved method for sealing a electrochemical cell stack comprises forming an encapsulating seal with different material and conditions, such as with a seal material having a curing temperature greater than the operating temperature of the cell stack.      The encapsulating seal can be formed by injection molding, potting or other suitable methods.

Abstract: The pivoting flare stack swing arm is characterized as follows, The flare stack pivots on the swing arm from a horizontal to a vertical position via use of mechanical advantage, to be locked in position, allowing the specified vertical height required for flaring. The unit is then designed to swing away from the structure to allow for defined distance required.  Outriggers are then deployed to maximize stability of the flare stack. The flare stack is now secured to be put into service.

Patent CA-2378475-A1 (CA)
Inventor: OSHITA KAZUYUKI
IPC: B01D53/86
Filed: 2001-04-12
Abstract: An organic halogen compound-decomposing catalyst is provided, which affords excellent decomposing percentages even at low temperatures, while there is no fear of re-synthesizing dioxines and brominated dioxines.      An organic halogen compound-decomposing catalyst is obtained by reacting a Pt salt and/or a Pd salt, an alkoxide derivative of Ti compound and an amino acid as an organic binder in a solvent, thereby synthesizing an organic metal precursor containing Pt and/or Pd and Ti in molecules thereof, and heating the organic metal precursor. This catalyst may be carried on a surface of a clean side of a ceramic filter. Since active points can be increased by uniformly dispersing the Pt and/or Pd particles in Ti particles, the catalyst has higher activity as compared with those obtained by conventional processes, and can exhibits excellent decomposing effects even at lower than 200°C.

Abstract: A two-part connector structure (22, 32) includes a male connector part (32) and a female connector part (22) which are mutually engageable to open fluid communication between the connector parts (22, 32). For example, the connector parts (22, 32) may be used to establish fluid communication between a container (12) and a conduit (14). The connector parts (22, 32) are disengageable from one another to discontinue fluid communication between them, and also to close communication between ambient and each of the container and the conduit. The male connector part (32) includes a mounting structure (32a) for supporting on the female connector part (22), and also includes a guide structure (44) effective to guide a male probe portion (36) of the male connector part (32) into engagement with the female connector part (22). A handnut (34) of the male connector part (32), and is effective upon manual rotation to cause axial relative movement of the male probe portion (36) into or out of engagement with the female connector part (32). This invention provides a connector structure (22, 32) with considerably lowered manual engagement and disengagement forces, along with increased convenience and ease of use.

Abstract: A dispersing element for a rear projection screen assembly is sensitive to the polarization of the light passing through the element. In particular, the element disperses light having a first polarization differently from light having a second polarization orthogonal to the first polarization. The dispersing element may be aligned with a polarization axis neither parallel nor perpendicular to the polarization of the light passing through the element. The dispersing element may also be employed with a polarizer to remove unwanted light that propagates through the dispersing element. The dispersing element may also be rotatably mounted relative to a polarized light source so as to vary the angle between the polarization axis of the element and the polarization direction of the light.

Abstract: A first Group III nitride compound semiconductor layer 31 is etched, to thereby form an island-like structure such as a dot-like, stripe-shaped, or grid-like structure, so as to provide a trench/post. Thus, a second Group III nitride compound layer 32 can be epitaxially grown, vertically and laterally, from a top surface of the post and a sidewall/sidewalls of the trench serving as a nucleus for epitaxial growth, to thereby bury the trench and also grow the layer in the vertical direction. In this case, propagation of threading dislocations contained in the first Group III nitride compound semiconductor layer 31 can be prevented in the upper portion of the second Group III nitride compound semiconductor 32 that is formed through lateral epitaxial growth. As a result, a region having less threading dislocations is formed at the buried trench.

Title: Methods of modulating drug clearance mechanisms by altering sxr activity
Inventor: SYNOLD TIMOTHY W
IPC: G01N33/50
Filed: 2001-03-23
Abstract: The present invention relates to new methods of modifying drug clearance and avoiding multi-drug resistance by modifying SXR activity. SXR is a transcriptional activator of MDR1, cytochrome P40-3A4 and cytochrome P40 2C8. SXR activation can significantly increase the metabolic inactivation and efflux of a wide range of chemotherapeutic agents, for example taxanes. Reducing and/or preventing SXR activation therefore diminishes drug resistance and drug clearance and forms the basis of important therapeutic methods which increase the performance of drugs, such as taxanes. Screening and drug identification methods are described which can identify drugs which are not susceptible to SXR related inactivation and increased efflux. In addition, drugs which can reduce these effects for other agents are provided.
