Patent CA-2215428-C (CA)
Title: Total trunk traction exerciser
Inventor: MCQUINN ANDREW JAMES
IPC: A63B21/062
Filed: 1999-02-08
Granted: 2006-11-28
Abstract: The invention disclosed is an exercise device comprising a frame holding a seat above the floor that has a resistance loaded backrest for the purpose of rehabilitating atrophied spinal support muscle through progressive resistance exercise while the spine is under pain alleviating traction. The backrest is resistance loaded for both traction, and extension resistance or flexion resistance. This makes needed exercise possible for those who are hindered from such therapy by spinal compressive related pain. The exercise resistance is transmitted to the patient via a horizontal axis backrest, and can be weighted either positively for back resistance, or negatively for abdominal resistance, at the same time traction is applied from a backrest suspension system applying resistance to the user attached to it in the direction that decompresses the spine.

Abstract: A method of preventing scrapers on a reciprocating sucker rod from wearing grooves in well tubing. The first step involves providing at least one scraper having a body with two opposed spiral vanes each of which extends 180 degrees around the body and flow channels positioned between the spiral vanes.  The second step involves securing the scraper to a reciprocating sucker rod. The third step involves positioning the sucker rod within well tubing having an inner circumference with the two opposed spiral vanes engaging 360 degrees of the inner circumference of the well tubing while fluids bypass the body by means of the flow channels.

Abstract: The invention relates to a process for the chlorosulphonation of polyarylene sulphide in which the polyarylene sulphide is completely dissolved in chlorosulphonic acid at a temperature of -10 to +20 .degree.C, then agitated at reaction temperatures in the +5 to +20 .degree.C range for a reaction time of 180 min at the most, possibly with the addition of oleum or acetic anhydride and then precipitated in an aqueous medium. The polyarylene sulphide is preferably poly-p-phenylene sulphide. The invention also relates to chlorosulphonated polyarylene sulphide produced by this process, which dissolves in a quantity of 10 to 50 wt.% in N- methyl pyrrolidone and has a mean molecular weight M w of .gtoreq. 50,000 g/mol. Finally, the invention also relates to the use of chlorosulphonated polyarylene sulphide for the production of moulding, foils, fibres or diaphragms with a proton conductivity in the 2 to 200 mS/cm range.

Title: Steel rule die with closely nested cavities
Inventor: JOHNSON MICHAEL J
IPC: B26F1/44
Filed: 1996-10-18
Granted: 2004-09-14
Abstract: A steel rule cutting die for cutting fixed patterns in a single or plurality of stacked material layers (6) according to the shape of the steel rule. The invention provides for a decrease in the quantity of scrap material produced, by minimizing the amount of gap between adjacent cavities (2) in the steel rule cutting die. Presharpened steel rule is used with the cutting edge (5) shifted to the outboard side of the cavity thus reducing the amount of compression or wedging of scrap material between adjacent cavities, and thus allowing adjacent cavities to be positioned closer to one another or to contact one another without reducing the ability to remove the scrap material after the cutting operation. Frayed scrap material can be evacuated through the base of the die by providing evacuation holes (17) in the base substrate of the die as well as providing for evacuation of scrap material from marker notch locations (16) along joined sections of adjacent cavities. A variety of cavity shapes can be accommodated.

The first to third vent passages each have one end thereof located in the fuel tank at an upper front location thereof, an upper rear location thereof, and an upper central location thereof, respectively. An anti-overcharging valve is arranged in the fuel tank and connected to the other end of the third vent passage. A first valve is connected to the one ends of the first and second vent passages, and a confluent vent passage extends from the first valve toward an internal combustion engine installed in the vehicle. A second valve is arranged across the confluent vent passage on one side of the first valve closer to the engine. The third vent passage has the other end thereof connected to the confluent vent passage at a location intermediate between the first valve and the second valve. The sum of set pressure of the first valve and set pressure of the second valve is set to a value higher than head pressure of the fuel tank assumed when the fuel tank is fully charged.

Title: Call forward managed rerouting
Inventor: STUMER PEGGY MARIE
IPC: H04M3/54
Filed: 1997-02-11
Granted: 2002-04-09
Abstract: A method and system of managing call forwarding includes establishing criteria for selecting among possible links between nodes for forwarding calls from an originating node to a destination node. In the preferred embodiment, the selection of the possible links is made at a called node from which the call is to be forwarded. Based upon the administrable criteria, there is a determination as to whether an intermediate node along the call path between the originating node and the called node is to be selected for initiating the forwarding path. If an intermediate node is selected, a request is transmitted to the intermediate node to initiate the forwarding path to the destination node. On the other hand, if no intermediate node is selected, a determination is made as to whether to initiate the forwarding path from the originating node or from the called node. Again, the determination is made according to the administrable criteria. Typically, the most important factor in selecting among the nodes relates to minimizing the link necessary to connect the calling party to the forwarded-to party, thereby releasing links for other use within a network.

Title: Method and apparatus for measuring pressure in a coriolis mass flowmeter
Inventor: PANKRATZ ANTHONY WILLIAM
IPC: G01F1/84
Filed: 1997-08-12
Granted: 2002-11-19
Abstract: A method for determining pressure in an operating Coriolis effect mass flowmeter (10). The Coriolis flowmeter flow tubes (130, 130') are vibrated in both a bending mode (as is normal for measuring mass flow rate) and in a twisting mode. The ratio of the fundamental frequencies at which the flow tubes vibrate in each of the two vibration modes is proportional to the pressure within the flow tubes. In the preferred embodiment, a sum/difference method initially isolates the superposed sinusoids representing the fundamental frequencies of the two vibrational modes. Fast conjugate gradient (FCG) digital filters (512, 514) are then used to rapidly estimate the fundamental frequencies in each of the two vibration modes. The estimated frequencies are then used by filter chains including digital notch (518, 508) and band pass filters (506, 1520) as well as recursive maximum likelihood (RML) digital filter (510, 522) techniques to enhance the bending mode and twisting mode fundamental frequency estimates. The enhanced bending mode andtwisting mode frequency estimates are used to determine the pressure within the flow tubes as a function of the ratio of the two frequencies as well as to center the notch and band pass filter chains used to enhance the bending mode frequency of the two vibration sensor channels for mass flow rate computations. The pressureso determined may then be used to correct mass flow rate computations or for other pressure measurement purposes per se.
