Title: Benzylic ether phenolic resole resins, their preparation, and uses
Inventor: DANDO THOMAS E
IPC: C08G8/10
Filed: 1996-07-17
Abstract: This invention relates to benzylic ether phenolic resole resins and the process for preparing them. The benzylic ether phenolic resole resins are prepared by heating phenol and an aldehyde in a sealed reaction vessel in the presence of a divalent metal catalyst without removing water generated by the reaction until an appropriate endpoint for the resin is reached. The benzylic ether phenolic resole resins produced by the process are preferably free or essentially free of unreacted formaldehyde and can be used in the resin component of phenolic-urethane foundry binders to make foundry cores and/or molds by the cold-box and no-bake processes. The cores and/or molds are used for making metal castings.

Title: Fuel cell system for electric generation, heating, cooling and ventilation
Inventor: HSU MICHAEL S
IPC: F24J3/00
Filed: 1997-07-16
Abstract: An energy system that couples or integrates an electrochemical converter, such as a fuel cell for the production of electricity, with a Heating, Ventilation and Cooling (HVAC) system, is disclosed. Waste heat (16) generated by the fuel cell is radiatively, convectively, or conductively directed to a thermal component, such as a heat-actuated chiller (30) or a boiler, of an HVAC  system. The HVAC system receives the waste heat to produce a conditioned fluid, e.g. heated or cooled air or water, or steam, for heating, cooling, or industrial uses. The invention provides an improved efficiency energy system capable of providing electricity, heating and cooling, such as for a commercial facility or for residences. Also disclosed is an interface exchange element for convectively coupling an electrochemical converter to the HVAC  system. The interface exchange element receives heated exhaust gases generated by the fuel cell and extracts heat therefrom for transfer to a thermal component, such as heat-actuated chiller or a boiler, of an HVAC system.

Inventor: JOHNSON BRUCE D
IPC: G01N7/04
Filed: 1999-03-22
Abstract: A method and apparatus for the measurement of a specific dissolved gas in a liquid. The apparatus comprises a gas-permeable membrane for separation of dissolved gas from the liquid; a gas collecting chamber communicating with and disposed on the side of said membrane remote from the liquid for collecting dissolved gas separated from the liquid; a second chamber for receiving a gas absorbing or adsorbing material for the specific dissolved gas; means for interconnecting the second chamber to one gas collecting chamber to allow contact of the dissolved gas with the gas absorbing or adsorbing material; and pressure measuring means for providing a measurement of the difference of pressure of the gas resulting from the absorption or adsorption of the specific selected gas, thereby providing a measure of the quantity of the selected specific gas present in the liquid. The method involves interfacing the liquid to be measured with a gas-permeable membrane to allow permeation and separation of dissolved gas from the liquid, and confining separated gas to a chamber; establishing equilibrated pressure of the separated gas within the chamber representative of the sum of partial pressures of all dissolved gases; contacting the gas with a material that absorbs or adsorbs the specific selected gas to be measured, and determining the pressure reduction resulting from the absorption or adsorption of the specific selected gas, to provide a measure of the specific selected gas present in the liquid.

Patent CA-2276175-A1 (CA)
Inventor: ROEKER DAVID C
IPC: A46B9/02
Filed: 1997-12-15
Abstract: A rotary surface treatment tool is attached to a rotational driver with a kit.  The surface treatment tool includes a base with a middle portion around a center hole, and one or more attachment knobs are placed on the front side of the middle portion. An attachment plate or retainer nut has a flange which extends radially over the middle portion of the base. The attachment knobs mate with holes in the flange of the retainer nut. The surface treatment tool is tightened onto the shaft by turning the surface treatment tool, with the attachment knob turning the retainer nut and thereby tightening the retainer nut to the threaded shaft. Assembly and tightening without any tools is thus facilitated. The base may be made of a flexible, shape-retaining material, and recesses are provided behind the attachment knobs to permit use with a retainer nut without a mating recess. The surface treatment tool may be a brush having bristles which extend at about 90~ to the plane of the base. The bristles are disposed in a pattern of helical bristle curves, with each bristle curve providing a relatively continuous sweep.

Patent CA-2277265-A1 (CA)
Title: Link aggregation in ethernet frame switches
Inventor: ALEXANDER THOMAS
IPC: H04L45/74
Filed: 1999-07-09
Abstract: Data packets containing source and destination addresses are received on one or more incoming ports for distribution on one or more outgoing ports. An address look-up table stores previously processed source and destination addresses, together with source and destination contexts associated with the respective source and destination addresses. The contexts represent either a specific physical port, or an aggregated grouping of ports. A distribution table stores, for each aggregated grouping of outgoing ports, a corresponding aggregated group of identifiers of specific outgoing ports. As each packet is received, its source and destination addresses are extracted and the address look-up table is searched for those source and destination addresses. If the address look-up table contains those source and destination addresses then the source and destination contexts associated with those source and destination addresses are retrieved from the address look-up table. If the address look-up table does not contain a source address corresponding to the extracted source address, then a source context corresponding to the extracted source address is derived and stored in the address look-up table with the extracted source address. If the retrieved destination address context represents a specific outgoing port, then the received packet is queued for outgoing transmission on that port. If the retrieved destination address context represents an aggregated grouping of outgoing ports, then the identifiers for the outgoing ports comprising that grouping are retrieved from the distribution table, and the received packet is queued for outgoing transmission on all of the outgoing ports comprising that grouping.

Patent CA-2281648-A1 (CA)
Inventor: ROTHMAN JAMES E
IPC: C12N5/02
Filed: 1998-02-13
Abstract: The invention relates to methods and compositions which utilize the emission of light to monitor changes in microenvironments involving cells. The invention is especially useful for monitoring exocytotic activity such as detecting quantal release of synaptic vesicles. Fusion proteins of Cypridina luciferase and synaptotagmin-I or VAMP/synaptobrevin-2 were targeted to synaptic vesicles and, upon exocytosis, formed light-emitting complexes with luciferin present in the extracellular medium. Photon emissions in the presence of a depolarizing stimulus can be observed with these systems. pHsensitive mutants of green fluorescent protein are also provided, which are useful for visualizing exocytosis and for imaging and measuring the pH of intracellular compartments.
