Patent CA-2172649-A1 (CA)
Inventor: BOYLE VALERIE Y
IPC: H04Q3/00
Filed: 1996-03-26
Abstract: A method for automatically transferring customer data among a plurality of central office switches comprises receiving a work order message from a central provisioning system at a message directing switch. The message directing switch is in communication with at least one message receiving switch in a local telecommunication network. Upon determining that a particular work order message received from a central provisioning system requires a coordinated data exchange, a data query is formulated in the message directing switch to retrieve specific data, such as data relating to a customer directory number from a message receiving switch. Once the data is received in the message directing switch, the data is processed and retained in the message directing switch or delivered to another switch in the telecommunications network. The method and system alleviates the need for manual retrieval and installation of specific customer line data when a directory number is moved from one central office switch to another.

Title: Metal pipe with integrally formed liner and method of fabricating the same
Inventor: ANDRE JAMES R
IPC: B29C48/09
Filed: 1993-11-18
Abstract: A metal pipe and method of forming the same with an integrally formed liner (16) for use in corrosive and abrasive environments is disclosed. The liner (16) is comprised of a relatively thick high density polyethylene which is thermally bonded to the metal pipe. An intermediate coextruded polymer layer of ethylene acrylic acid and a polyethylene/ethylene acrylic acid blend is applied to the metal pipe to facilitate thermal bonding. The intermediate layer (11) is applied to the sheet metal in a pre-treatment process prior to roll forming ribs (12) into the sheet metal. The polyethylene liner (16) is applied after the ribs (12) are formed to provide a smooth, hydraulically efficient surface which is resistant to the corrosive action of sulfuric acid and the like encountered in sanitary applications, as well as abrasion caused by the flow of water-borne debris such as dirt and gravel as is encountered in culvert applications. Various means for further securing the polyethylene layer to the metal pipe surface are disclosed.

Abstract: This invention relates to a new method for making large underground storage caverns in bedded or domal salt deposits for the storage of fluid materials in areas where solution mining water temperatures are low by a process which significantly reduces the amount of time required to make equivalent sized underground storage caverns and which is economically feasible and friendly to the environment. The process includes the warm water solution mining of the underground salt deposits in a manner which conserves the heat contained in the supernatant brine from the underground cavity and employs this heat as a significant source for warming the water employed in the solution mining operation.
Patent CA-2188583-A1 (CA)
Title: Force sensing assembly and method for a product delivery system
Inventor: BACCO DAVID R
IPC: B31B50/06
Filed: 1996-01-23
Abstract: A force sensing assembly measures a magnitude of a force generated at the tabs (18) in a product delivery system. The product delivery system can be one in which a force is produced at the tabs by the weight of the stack, by a paddle (12) pushing an end of the stack (14), or by another similar type of advancing mechanism. In a preferred embodiment, the force sensing assembly has a pair of tabs connected to a cross-bar (20) which extends across the stack and which is connected to the frame of the feeder through a bell crank (24) at one end and a lever (20) at the other end. The bell crank has one arm connected to the cross-bar (20) and a second arm connected to a load cell (42). The force at the tabs causes the lever and bell crank to rotate, with the force being transmitted through the bell crank, through a spring, and then to the load cell. The load cell generates a force signal which is supplied to a controller for adjusting the amount of force at the tabs. The controller adjusts the force by adding more products to the stack or by advancing the stack closer to the tabs. The load cell preferably has a stopper for preventing an excessive amount of force from reaching the cell.

Title: Injection molding nozzle with edge gate inserts and sealing ring
Inventor: BOEHNEN DANIEL A
IPC: B29C45/72
Filed: 1996-11-18
Abstract: Edge gated injection molding apparatus wherein each heated nozzle has the combination of a circular sealing ring extending around it and several gate inserts, each extending radially outward from the nozzle in alignment with a gate. The sealing ring bridges an insulative air space between the heated nozzle and the surrounding wall of a well in the cooled mold to provide a sealed portion of the space around the gate inserts. The outer end of each gate insert is spaced a predetermined distance "D" from the wall of the well in which the nozzle is seated to form an opening therebetween. The opening is large enough to allow pressurized melt to flow outwardly therethrough into the sealed front portion of the space between the nozzle and the surrounding wall of the well and small enough to prevent the partially solidified melt in the sealed front portion of the space being sucked back into the melt stream during subsequent injection cycles.

Title: Pick resistant window lock manual control
Inventor: JOHNSON DOUGLAS G
IPC: E05C9/00
Filed: 1996-12-05
Abstract: A lockable window, and a manual control for a lockable window. The window includes a window sash having a first locking member and a window frame having a second locking member mounted thereon for movement between a locked position cooperating with the first locking member for locking the sash to the frame when closed against the frame and an unlocked position clear of the first locking member to allow movement of the sash relative to the frame. The frame also has an opening therein for allowing access to the second locking member from an interior side of the frame. The lock control has a housing including an enclosure open on one side with a flange around the open one side, the housing being mounted with its enclosure substantially in the frame opening and its flange on the interior side of the frame. A handle is pivotally secured in the housing enclosure and includes an opening at one end. A hard, resilient plastic retainer substantially surrounds the frame opening andis disposed between the frame interior side and the housing flange to substantially seal against leakage through the frame opening to the frame interior side. The retainer further includes a flexible hook portion received in the handle opening when the handle is in the locked position, where pivoting the handle out of the locking position requires a pivoting force sufficient to flex the hook portion clear of the handle. The hook portion is adaptable for use with both right and left hand operation. The handle is operably connected to the second locking member so that pivoting of the handle between locking and unlocking positions selectively moves the second locking member between the locked and unlocked positions.
