Patent CA-2101127-C (CA)
Inventor: BLACK JAMES EDWARD
IPC: H04M3/36
Filed: 1993-07-22
Granted: 1999-06-22
Abstract: To provide a complete picture of the calling pattern of calls placed to a destination entity, which permits the destination entity's routing plan to be adequately administered, a) information is collected about all call attempts to particular, specified dialed numbers even before they are switch routed, including even calls terminated before a network control point (NCP) returns instructions as to where to route the call and, if applicable, after they are rerouted and b) the collected information is periodically delivering as it becomes available, for use by the destination entity, without requiring the calls being monitored to have been terminated. Thus, for example, information is collected about calls being held by the NCP in a queue even before the calls are NCP routed. The collected information also includes information for calls that were never routed, because they were terminated before routing, independent of whether they were placed in a queue. If applicable, additional information is collected about the rerouting of those calls that are rerouted. Additionally, information is collected concerning the performance of a network control point, including information on queue performance and routing location selectionperformance.

Granted: 1998-08-25
Abstract: A system is described to separately furnish to an injector apparatus that is placed within a pipe two or more grout components. The injector apparatus is secured in position in the pipe by components of the injector apparatus that are urged into a position of cooperation with a modified section of pipe as a consequence of the increased hydraulic pressure that occurs within the injector apparatus during the pumping of one of the grout components thereinto. The two or more grout components after separately being furnished to the injector apparatus are first combined together by elements of the system and are then thoroughly mixed (reacted) together by other elements of the system to form a grout that is discharged from the system following their mixing together and prior to setting of the grout in ideal proximity with respect to a crack or crevice requiring grout application. All components of the system are recovered for subsequent use elsewhere.

Abstract: A long wearing deep tillage sweep includes a central point member having a leading tip and attached to a shank at an angle to the horizontal of approximately 30 degrees.  A pair of wings having the shape of a parallelogram are fixed to the lower, forward portion of the point with the sides of the wings parallel to the forward direction of travel and with the leading and trailing edges extending outwardly from the member and parallel to the surface of the ground when the shank is in the normal field-working position.  The top surface of the wings has a shallower angle than the point surface, which, together with the horizontal leading and trailing wing edges, reduces soil disturbance.  The wings are closely adjacent the tip of the point member so that the angle of the resultant force on the sweep closely approximates that of a straight point alone and the depth of tillage is more consistent than tools having wings offset a greater distance from the leading tip.  The leading portions of the wings are hardened, and the wings and point include upwardly and rearwardly directed rear walls which provide a self-sharpening effect as the leading edges wear.

Abstract: A novel friction wedge for use in a bolster pocket of a truck of a railroad car, comprises a metal body portion having a vertical wall and one or more pad members supported on the surface of a pad-support body. The metal body portion has a vertical wall the exterior surface of which body bears against a guide column of the side frame. The pad-support body, which is part of the metal body portion, is provided with an inclined surface upon which is secured a polymer pad with a central planar inclined surface which bears against the correspondingly inclined surface of the pocket. The pad member is required to be formed from specified reaction injection molded (RIM) polymers which it is found to be free of microscopic voids > 20µm and therefore, fully dense, unlike prior art polymer pads for friction wedges. This property of being fully dense unexpectedly allows the pad to have specified physical properties which permit a railroad car truck equipped with the friction wedges to operate with exceptional reliability, safety and for a long period of time. In a particular embodiment, the design of the pad(s) permits relative movement of the pad and the metal body of the friction wedge to locate the center of pressure accurately on the friction wedge, under load, and this further improves the effectiveness of the friction wedge and extends its useful life.
