Patent CA-2128401-A1 (CA)
Title: Butterfly Valve Assembly
Inventor: PEARSON JAMES E
IPC: F16K1/22
Filed: 1994-07-19
Abstract: A valve of the type for controlling engine coolant flow to a heater core having a resilient butterfly valve formed of thermoplastic elastomeric material. The outer periphery is sufficiently resilient to absorb actuator overtravel in the seated condition. The butterfly has formed integrally therewith a central hub with torque-transmitting surfaces molded therein and a pair of oppositely disposed stiffeners extend outwardly from the hub in the central region of the butterfly. Assembly is simplified by placing the butterfly in the body and inserting a winged actuator shaft through journal holes in the body into the butterfly hub such that the wings on the shaft engage the torque-transmitting surfaces in the hub.

Title: Electronic level displaying inclination with regard to instrument length
Inventor: HEGER CHARLES E
IPC: G01C9/06
Filed: 1993-08-11
Abstract: An electronic level includes a visual scale (12) similar to a ruler scale having a number of parallel line segments (12a, 12b, 12c). The inclination of the device is shown by illuminating various of the scale line segments on either side of a central line (12a), indicating the inclination away from null. When the device is at a null only the central scale line is illuminated. Each scale line segment indicates a fraction of an inch of inclination per e.g. two feet of horizontal distance (the two feet being the level length in one version) which conforms to the normal use of such levels by building tradesmen. The level is calibrated by taking two readings with the level rotated 180· between readings. The readings are averaged and negative feedback is provided to the level sensor itself to null out any system mechanical or electrical offsets.

Patent CA-2143892-A1 (CA)
Title: Method and system for real-time monitoring of earth formation fracture movement
Inventor: WRAIGHT PETER D
IPC: E21B47/10
Filed: 1995-03-03
Abstract: A method of monitoring formation fractures in real-time is performed in which a fluid containing a radio-active tracer element is pumped at a high pressure down a wellbore into a formation. As the fluid creates fractures and moves through the formation gamma-rays are emitted from the radio-active tracer element in the fluid. Detector means placed at predetermined locations in the wellbore continuously detect these gamma-rays. Gamma-rays emitted from wellbore fracture fluids are distinguished from formation gamma-rays and the detected formation gamma-rays are counted. As the fracture fluid approaches the height or vertical depth of these detector means, the gamma-ray count increases. Once the gamma-ray count reaches a predetermined level, the fracture will have reached a desired location in the formation and pumping of the fracture fluid will stop.

Abstract: A method for identifying highway access ramps in a database medium for use as locations for route calculation. Initially, first road segments which belong to a highway and which are connected to at least one access ramp are identified.  The first road segments are sorted according to the highway to which they belong.  A highway direction is determined for each first road segment.  The first road segments belonging to a first highway are sorted according to highway direction.  The first road segments belonging to the first highway and of each highway direction are sorted according to position, thereby forming a highway segment list for each direction of the first highway.  Highway access ramps are identified for each first road segment in the highway segment list.  The locations for the highway access ramps are stored in the database medium.  Highway access ramps are identified in this manner for each highway in the database medium.

Title: Method for attaching a flexible inner bag to the inside of a squeezebottle
Inventor: HARDING STEPHEN WAYNE
IPC: B29C65/36
Filed: 1995-07-07
Abstract: A method for sealing a flexible inner bag inside a squeezebottle so that the flexible inner bag will invert in order to dispense viscous fluids. The method is particularly useful in single-piece squeezebottles which have a small ratio of discharge opening cross-section to body cross-section. In practicing the presentinvention, a flexible inner bag has heat-activated adhesive stripes applied to the upper half of its exterior. The flexible inner bag is inserted into a squeezebottle through the discharge opening and then expanded inside the squeezebottle by compressed air. After the flexible inner bag is fully expanded, and with pressure applied to the inside of the flexible inner bag, heat is applied either to the inside of the bag or to the outside of the squeezebottle by hot air, steam, radiation, or induction heating of metal particles in the adhesive. The adhesive is heat-activated and the upper half of the flexible inner bag is thereby attached to the inner side wall of the squeezebottle.

Title: Optical communication system
Inventor: FLANAGAN THOMAS P J
IPC: H04J14/02
Filed: 1995-11-29
Abstract: A discontinuous ring is formed by separate bidirectional optical communication links, with possibly different transmission speeds, synchronous or asynchronous transmission, and ratios of working to protection channels, each linking a pair of terminals in different nodes of a communication system. To protect protection-switched traffic on a communication link from a link failure, it is routed around the ring via the protection channel of the other communication links. To this end, an optical switch is provided between the protection channel of each link and the associated terminals in each node, and is controlled differently in nodes adjacent the link failure and in nodes not adjacent the link failure to route the protection-switched traffic accordingly. Rapid protection switching is facilitated by controlling the optical switches using wavelength detectors directionally coupled to the protection channel at each node.
