Patent CA-2214838-C (CA)
Inventor: SMITH AVRIL JOY
IPC: H04L12/54
Filed: 1996-03-08
Granted: 2008-02-26
Abstract: In a broadband switching system for the switching of asynchronously transferred cells of data, a dynamic bandwidth controller (DBC) controls the application of data cells to an input port of the system, the data cells being supplied by a number of transmitting end-systems. When an end-system begins transmitting data cells, the DBC detects the presence of incoming cells and requests bandwidth from a connection admission control (CAC) forming part of the system. The switching system stores a table associating a number of signal sources connected to the ingress with respective predetermined transmission bandwidths and, preferably also, maximum delay times. When arrival of cells from one of the sources at the input port is detected, the DBC sends a request signal for the relevant predetermined bandwith to the CAC and delays transmission of the cells until at least the predetermined bandwidth is allocated. This delay is typically effected by sending a cell rate indicator signal back to the input port for placing the source in a halt mode. If no allocation of bandwidth has occurred before the respective maximum delay time, bandwidth is allocated by robbing bandwidth from other signal sources.

Abstract: A trail management system for a transport network comprises a database storing data describing each of a plurality of actual and intended/planned trails within a network. Each trail is described in terms of a state model, in which the trail is recorded as being in one of a plurality of stable states, eg ready for service, not ready for service, existing in the network but not fully recorded in the network management system, or assigned for deletion from the network. The trail data is modified by a set of automatic processes, by means of which a trail data may transition between stable states. Each trail data may adopt one of a plurality of sub-states, eg fully provisioned, incomplete, in conflict with another trail, inconsistent with another trail, unprovisioned, or unsupported by network resources. The network management system learns of actual existing trails within the network and checks for consistency of actual trails with stored trail data.

The paint is taken to a storage tank (41), with a portion of the paint going to a control cell, and with the data being compared with the data of the standard paint for adjustment of color, coverage, and viscosity. An internal cleaning system uses nitrogen to push the paint out from the pipes which are then cleaned with pumped solvent.

Abstract: The present invention provides a narrow band infrared water cut meter for detecting a full water cut range of a flow stream. The water cut meter includes a light source probe for irradiating the flow stream with a narrow band of infrared light and a light detector probe for sensing infrared light passed through the flow stream. For a narrow band of infrared light of a predetermined wavelength, there is a large difference in the absorption of infrared radiation between oil and water. At such a wavelength, the narrow band of infrared light is substantially transmitted through water content and gas content of the flow stream and substantially absorbed by oil content of the flow stream. The water cut meter thus differentiates oil by treating gas like water. Unlike other water cut meters, the narrow band infrared water cut meter is independent of variations of oil and water densities, salinity, oil emulsions, varying flow rates, and the gas content of a flow stream.

Patent CA-2333356-C (CA)

Abstract: The present invention is a method of separating a short-lived daughter isotope from a longer lived parent isotope, with recovery of the parent isotope for further use. Using a system with a bi-directional pump and one or more valves, a solution of the parent isotope is processed to generate two separate solutions, one of which contains the daughter isotope, from which the parent has been removed with a high decontamination factor, and the other solution contains the recovered parent isotope. The process can be repeated on this solution of the parent isotope. The system with the fluid drive and one or more valves is controlled by a program on a microprocessor executing a series of steps to accomplish the operation. In one approach, the cow solution is passed through a separation medium that selectively retains the desired daughter isotope, while the parent isotope and the matrix pass through the medium. After washing this medium, the daughter is released from the separation medium using another solution. With the automated generator of the present invention, all solution handling steps necessary to perform a daughter/parent radionuclide separation, e.g. Bi-213 from Ac-225 "cow" solution, are performed in a consistent, enclosed, and remotely operated format. Operator exposure and spread of contamination are greatly minimized compared to the manual generator procedure described in U. S. patent application 08/789,973 herein incorporated by reference. Using (16) mCi of Ac-225, there was no detectable external contamination of the instrument components.
