Patent CA-2144680-A1 (CA)
Inventor: MACLAGGAN LAWRENCE C
IPC: F16K43/00
Filed: 1995-03-15
Abstract: There is provided an apparatus for installing and/or replacing a valve on an existing pipe which may be under fluid pressure.  A first versionof the apparatus includes a main housing having a pair of separable housing members together defining a first bore extending along a first axis for receiving the pipe and embracing the same.  These housing members also define a second bore extending along a second axis intersecting the first axis in transverse relation thereto.   An annular cutter disposed in said second bore is capable of being advanced along said second axis for cutting and removing a section of the pipe located within said main housing.   A further member is axially movable with said cutter along said second bore into a predetermined axial position adjacent the ends of said pipe after said pipe section has been removed by said cutter.   The further member has a port means extending transversely therethrough causing flow through said pipe to be selectively enabled and disabled when said further member is selectively moved or positioned such as to bring said port means into and out of alignment with said first axis along which the pipe extends.   A sealing means is located within said main housing for forming a fluid tight seal between the pipe and each of said housing members when in use and also around said further member when it is in said axial position for enabling and disabling flow through said pipe. A second version of the apparatus is also described hereafter.

Title: Hybrid series active/parallel passive power line conditioner with controlled harmonic injection
Inventor: DIVAN DEEPAKRAJ M
IPC: H02J3/01
Filed: 1994-06-14
Abstract: A power line conditioner  includes an active filter (34) coupled, in series, and a passive filter (72) coupled, in parallel to a three-phase power distribution network (43). The three-phase power distribution network (43) includes a voltage source (32) that induces three-phase input currents at a first end of the three-phase power distribution network (43). A load (30), circulating three-phase load currents, is positioned at a second end of the three-phase power distribution  network (43). The active filter controller (74, 76, 78) of the invention uses synchronous transformations to identify selected harmonic reference components corresponding  to individual harmonics of the three-phase load currents. The selected harmonic reference components are multiplied by a predetermined factor corresponding to a permissible percentage of the individual harmonics that may be injected into the supply voltage (32). This results in active filter reference signal components that are applied to the active filter (34). In response to the active filter reference signal components, the active filter (34) injects a permissible of harmonics into the supply voltage (32) so as to reduce the voltage distortion at the passive filter (72).

Title: Method and apparatus for applying surfacing material to shingles
Inventor: KOSCHITZKY HENRY
IPC: B05C19/06
Filed: 1996-02-15
Abstract: A device is provided for placing sharply demarcated patches on roofing products such as shingles or sheeting without the need for a double layer of asphalt. After the base sheet has been covered with a layer of coating asphalt, granules to form the patch are dropped on the base sheet through a hole in a belt which moves parallel to and just above the base sheet. The moving hole in the belt ensures that the patches will have sharp leading and trailing edges. The belt can have several holes for different size patches, and/or different blends of granules can be applied through the same or different holes. After the patches have been applied, the remainder of the sheet is covered with granules. Alternatively, the granules which drop on the spaces on the belt between the belt openings can be applied to the base sheet to form sharp edged patches, while the granules dropping through the holes in the belt can be removed and collected for re-use.

Patent CA-2179696-A1 (CA)
Title: Coated food
Inventor: DE VRIES HIELKE T
IPC: A23L7/10
Filed: 1996-06-21
Abstract: Provided is the use of a cation cross-linked polysaccharide coating for reducingthe glycemic response of a carbohydrate-containing food. The cation cross-linked polysaccharide coating may be formed from calcium cross-linked pectin or pectinate. The carbohydrate-containing food may be a rice grain, pasta shape, flour, starch or a piece of breakfast cereal.   Such a coated food may be prepared by coating a cross-linkable polysaccharide on a hydratable carbohydrate-containing food core. The food core is then hydrated by cooking the coated food core in an aqueous solution of cross-linking cations which simultaneously cross-link the coating. The resulting foods can be used in the diets of individuals suffering from diabetes, hypoglycemia or glycogen storage disease. They also have the effect of suppressing appetite or assisting in the performance of sustained physical activity.   The effect of coating the carbohydrate-containing food is slow down its rate of digestion in the small intestine. This in turn smooths out the release of glucose into the blood stream which otherwise would peak very sharply soon after the digestion of the food commences.

Title: Network architecture for routing of adjunct based services
Inventor: RICCIARDI DOMINIC
IPC: H04Q3/00
Filed: 1996-12-16
Abstract: The present invention is a novel architecture design for adjunct based architectures. The architecture is built on two key principles; routing traffic based on geographic origin and routing based on customer group. In order to implement the geographic routing, the communications network is split into regions. A method used to achieve optimal regions is described. Further realization of the geographic routing entails a design of the architecture regions, determining the number of adjuncts/region and equally distributing the loads across the adjunct sites. Also, described is the method for optimally homing traffic between the OAS and TAS A and between TAS A and TAS B. The architecture eliminates deficiencies in prior art architectures such as intertoll focusing, architecture instability and reliability.

Title: A wireless lan distributed access procedure providing priority for voice transmissions
Inventor: KRISHNAKUMAR ANJUR SUNDARESAN
IPC: H04L12/413
Filed: 1997-03-06
Abstract: A facility having particular data to transmit over a transmission medium, contends for access to the medium by transmitting a jamming signal over the transmission medium for a particular duration of time that is a small fraction of the amount of time that the facility had to thus far wait to so contend. If the transmission medium is found to be idle at the expiration of that time, then thefacility accesses the medium. Otherwise, the facility waits until the transmission medium again becomes idle and then re-contends for access.
