Patent CA-2227135-A1 (CA)
Title: Door corner joint with force transfer block
Inventor: REDMAN RONALD E
IPC: E06B3/964
Filed: 1998-01-15
Abstract: An improved joint construction for commercial metal doors is disclosed which utilizes a novel force transfer block. The force transfer block has spaced-apart flanges which engage corresponding reglets in a door stile. The inner faces of the flanges bear against the inner walls of the reglets. The flanges of the force transfer block are configured such that they will retain the block on the stile by way of an interference fit with the walls of the reglet. Thus the block does not have to be separately fastened to the stile. A rail abuts the stile and has a recessed portion into which the block is received. A threaded rod extends through the rail and into the stile, and tightening a threaded fastener onto each end of the rod clamps the rail securely between two stiles. The recessed portion of the rail has surfaces bearing snugly against at least two sides of the block such that twisting forces applied to the rail are transferred to the block. Twisting forces transferred to the block from the rail are transferred by the inner faces of the flanges to the inner walls of the reglets.

Title: Method for measuring the volume of liquid and/or solid in a suspension
Inventor: PASULA MARK J
IPC: G01N33/487
Filed: 1996-08-01
Abstract: The present invention is a method of measuring the total volume of solids in a suspension, comprising the steps of: establishing a potential across a predetermined spatial volume; passing a portion of the suspension through the predetermined spatial volume; substantially continuously measuring the potential across the predetermined spatial volume over a first predetermined period of time; comparing the measured potential with a baseline; and calculating the total volume of solids in the suspension as a function of a total absolute deviation of the measured potential from the baseline. The baseline is preferably a dynamic baseline, and is determined with reference to the starting point of a sharp rise in the measured potential.

Title: Process for silica and magnesium salts production from tailings coming from asbestos mining
Inventor: DELMAS MICHEL P B
IPC: B01J20/10
Filed: 1998-07-27
Abstract: There are numerous technologies to extract magnesium from tailings piles coming from asbestos mining.      In the invention we have found that silica which is a component of the asbestos fibers with magnesium oxide can be extracted with magnesium in combining extraction of the asbestos fibers by flotation (wet-milling technologies), the treatment of the water-soaked fibers with an acid and, after reaction the separation of the solid silica from the magnesium salt solution which can then process.      The silica shows a great surface area (400 -450 m2/g) which makes it a valuable product with many industrial applications. The extraction of these two products gives a good profitability to this new tailings processing technology.

Title: Continuous preparation of low unsaturation polyoxyalkylene polyether polyols with continuous addition of starter
Inventor: SHIH T THOMAS
IPC: C08G65/26
Filed: 1997-07-12
Abstract: A continuous process for the preparation of polyoxyalkylene polyethers using DMC catalysts as the polyoxyalkylation catalyst employs continuous addition of alkylene oxide in conjunction with continuous addition of starter and catalyst to a continuous oxyalkylation reactor. Despite the continuous introduction of starter, the molecular weight distribution of the polyether product is quite narrow, as indicated by the exceptionally low polydispersity of the product. The presence of low molecular weight species during the majority of the polyoxyalkylation also substantially eliminates extremely high molecular weight fractions having molecular weights greater than 100,000 Da, again without appreciably broadening molecular weight distribution. By withdrawing intermediate molecular weight polyether product or diverting a portion of the end product to prepare a catalyst/starter mixture, rapid and sustained reaction rates can be achieved while employing low molecular weight starters. Continuous build ratios in excess of 0.98 can be achieved.

Abstract: A method for producing a pant-style garment from a substrate having a plurality of tensioned garters. A garter is any continuous loop of elastic material or a laminate of elastic bands and one or more flexible backing sheets. In one embodiment a substrate is joined to one or more mandrels having tensioned garters fitted thereon. Substrate material is removed from within the loop of the garter, thereby forming apertures in the substrate. The substrate is folded along its longitudinal centerline such that its longitudinal edges meet. The substrate is subsequently joined along lines of joinder, and the substrate is cut into individual pant-style garments. In preferable embodiments, a process for providing elastics to the longitudinal edges of the substrate, thereby producing elasticized waistbands is included.

Title: System for short range wireless data communication to inexpensive endpoints
Inventor: SHOBER R ANTHONY
IPC: G06K7/00
Filed: 1999-03-30
Abstract: A system provides short range wireless data communication from a central control point (e.g., interrogator) to inexpensive endpoints (e.g., tags). The endpoints utilize the technology of modulated backscatter for transmission from the tags to the interrogator. The system uses a new downlink protocol for data transmission from the interrogator to the tags and a new uplink protocol for data transmission from the tags to the interrogator. Both protocols use a backoff/retry algorithm to randomly retransmit any non-acknowledged messages. System capacity from the tags to the interrogator is further enhanced by the use of uplink subcarrier frequency division multiplexing.

IPC: H04W24/08
Filed: 1997-11-11
Abstract: A cellular phone system, optimizing user demand by charging system subscribers according to a Variable Charge Rate (VCR) that is based on the price elasticity of the subscribers. According to the present invention, the service provider monitors the load in each cell and, for each cell, the service provider continuously determines a charge rate that can be tailored to specific subscriber category according to a number of variables, offering subscribers a VCR that is optimized for the individual cell's capacity and overall system capacity. According to an exemplary embodiment, subscribers may use mobile stations supporting the Short Message Service (SMS) to provide the subscribers with the broadcast VCR. The system can determine, in real time, optimal VCRs for individual cells to maximize revenue generated by the cell for any time of day. The VCRs may be selectively broadcast to the VCR-mobile station to inform subscribers of the current rate of charge for calls. VCRs may be tailored to specific categories of subscribers to provide better price differentiation between subscribers based on price elasticity of the subscribers categories.

Patent CA-2272571-A1 (CA)
Inventor: DALTON DAVID RICHARD
IPC: H01M2/10
Filed: 1997-12-23
Abstract: The invention relates to a housing which receives dry cells in an in-line or end to end orientation. The invention includes features which prevent the incorrect orientation by preventing dry cell terminals making contact with the necessary components. In this way it prevents premature dissipation of dry cells or their impairment. The mechanism by which these features do this is to recess one terminal namely that terminal which would be contacted by the positive terminal of a dry cell. In this way the negative terminal of a dry cell can never make electrical connection. Another feature of the invention is the provision of an aperture having a profile of a silhouette of a dry cell, which has advantages in low light situations, saves material, and allows for relatively easy extraction of dry cells from the cartridge.
