Title: In-line connector for window spacer frame tubing
Inventor: PETERSON WALLACE H
IPC: E06B3/667
Filed: 2000-07-18
Abstract: A self-centering in-line connector for insulated window spacer frame tubing. There is an elongate connector body having first and second ends. First and second ramps extend upwardly from the connector body towards a mid-point of the connector body. The base ends of the ramp portions are yieldingly mounted to the connector body, and the free ends have perpendicularly extending stop surfaces. Either end of the connector can be inserted into the open end of a section of spacer frame tubing. As this is done, the first ramp portion is depressed by the. web of the tubing so as to permit the tubing to pass thereover until insertion is arrested by the end of the tubing coming up against the stop surface of the second ramp member, at approximately the mid-point of the connector body. The other end of the connector is then inserted into a second section of tubing, which depresses the second ramp member so that the end of the second section oil tubing can be pressed into abutment with the end of the first, with the connector body being located centrally between the two sections of tubing.

Abstract: A method for controlling the rheology of aqueous systems, particularly for those intended for underground use, includes injecting an aqueous fluid containing a surfactant gelling agent into the system. The surfactant gelling agents are, for example, fatty aliphatic amidoamine oxides, salts of an alkoxylated monoamine with an aromatic dicarboxylic acid, and salts of an alkyldiamine with an aromatic dicarboxylic acid. The surfactant gelling agents can be adsorbed onto particulate supports to facilitate delivery of the gelling agent. The additives may be incorporated in the viscoelastic fluid to tailor its use in hydraulic fluids, drilling muds, fracture fluids, and in applications such as permeability modification, gravel packing, cementing, and the like.

Title: Unfinished wood product cutting optimization system
Inventor: JONES LARRY H
IPC: G01N33/46
Filed: 2000-08-16
Abstract: A system for estimating a velocity of a stress wave induced in an unfinished wood product such as a log or tree stem is used to maximize the value of wood products produced. An accelerometer is placed against the log while the log is struck with a pneumatic hammer. By monitoring the signals received at the accelerometer, the velocity of stress wave can be determined. Based on the velocity, an estimate of the modulus of elasticity (MOE) for the wood in the log is made. A price table is selected that relates different sizes of lumber having the determined modulus of elasticity to a current market value. The log is then cut such that the value of the lumber produced is maximized.

Patent CA-2322720-A1 (CA)
Title: Method and apparatus for selecting network entities
Inventor: WILLE ALLAN
IPC: H04L12/24
Filed: 2000-10-10
Abstract: Network management can be made more efficient by using a graphical user interface that is clear and concise in what network information is identified and subsequently displayed. One key to improving graphical user interfaces is the categorizing of network entities into a series of attribute layers that define different features of the network entities. For instance, a layer of attributes may include geographical regions, services, customers, or types of network entities. By selecting a base view from the group of geographical regions and then network features for filtering operations from one or more of the other attribute layers, the network entities defined by the selected network features can be identified and isolated with all other irrelevant network entities being filtered out. The advantages to this graphical user interface is especially evident when considering the case that a specific customer, service, or network entity requires special attention. Other features of this interface include bookmarking, archiving, and monitoring specific views of a network based off a base view along with one or more filtered network features.

Patent CA-2337083-A1 (CA)
Title: Anti-apoptotic compositions comprising the r1 subunit of herpes simplex virus ribonucleotide reductase or its n-terminal portion; and uses thereof
Inventor: LANGELIER YVES
IPC: A61K38/44
Filed: 1999-07-23
Abstract: The R1 subunit of herpes simplex virus (HSV) ribonucleotide reductase, which is expressed very early after viral reactivation, possesses an N-terminal domain of about 350 amino acids of unknown function. Using an adenovirus (Ad) inducible system we had demonstrated that a complete deletion of this domain produces a cytotoxic protein. We now report that apoptotic death induced by this truncated R1 could be completely prevented by coexpression of the full-length R1. The R1 antiapoptotic activity was further substantiated by showing that expression of this protein at low level can completely block apoptosis induced either by TNF-receptor family triggering in the presence of cycloheximide (CHX) or by Fas-L coexpression with an Ad recombinant. In both cases, the protection was lost when inhibiting tTA function with the tetracycline analog doxycycline shut down R1 expression. A level of R1 of 0.005 % total cell protein was sufficient for half-maximal protection against TNF.alpha.+CHX. By monitoring caspase 8 activation either by immunoblot with an antiserum visualizing the inactive 56-kDa proform and the active 18-kDa species or by an in vitro assay using ETD-AFC as caspase 8 specific fluorescent substrate, we found that the strong activation of caspase 8 induced either by TNF-.alpha.+CHX or Fas-L expression was prevented by the R1 protein. Finally, using an HSV-1 R1 deletion mutant, ICP6.DELTA., we obtained direct evidence for the importance of HSV-R1 in protecting HSV-infected cells against cytokine-induced apoptosis. These results show that, in addition to its reductase function which is essential for viral reactivation, the HSV R1 could contribute to viral propagation by preventing apoptosis induced by the immune system. The N-terminal domain by itself is as anti-apoptotic as the whole RI protein. An anti-apoptotic agent and a composition derived therefrom are described and claimed.
