Patent CA-2294063-A1 (CA)
Inventor: RUBBIA CARLO
IPC: G01V5/04
Filed: 1997-06-19
Abstract: A material is exposed to a neutron flux by distributing it in a neutrondiffusing medium surrounding a neutron source. The diffusing medium is transparent to neutrons and so arranged that neutron scattering substantially enhances the neutron flux to which the material is exposed. Such enhanced neutron exposure may be used to produce useful radio-isotopes, in particular for medical applications, from the transmutation of readily-available isotopes included in the exposed material. It may also be used to efficiently transmute long-lived radioactive wastes, such as those recovered from spent nuclear fuel. The use of heavy elements, such as lead and/or bismuth, as the diffusing medium is particularly of interest, since it results in a slowly decreasing scan through the neutron energy spectrum, thereby permitting very efficient resonant neutron captures in the exposed material.

Patent CA-2299127-A1 (CA)
Title: Method and apparatus for media access control for packet transmission over a buffer insertion ring
Inventor: COTTREAU PETER MARTIN KENNETH
IPC: H04L12/433
Filed: 2000-02-22
Abstract: An algorithm for media access control over nodes in a buffer insertion ring is described. Each node computes a local add rate and an advertised rate which it communicates to its upstream link partner node. The rate calculations are based on a locally computed tandem rate and a downstream rate received from a downstream link partner node. The algorithm ensures rapid convergence to a fair add rate at which nodes share link resources to avoid starvation in the ring. The advantages include short head of line delay, low operating overhead, and good bandwidth utilization.

Inventor: MILLER SCOTT A
IPC: E02D33/00
Filed: 2000-04-12
Abstract: Methods and apparatus enabling the length of a reinforcing geogrid for earthen structures to be determined even when the geogrid is buried. The preferred geogrid body comprises a plurality of spaced apart, elongated spans that are regularly intersected by similar, elongated, transverse spans. Voids defined between intersecting body spans facilitate the attachment of the geogrid to retaining walls, or other wall or earthen structures. A test line, preferably an electrically conductive wire, is molded into the geogrid body. The length of this conductor is electrically calculated and displayed to determine the length of the buried geogrid. Preferably an electrical pulse is generated and applied to the geogrid and a return echo is thereafter detected. The time difference between the pulse application and the return echo is electrically sampled and correlated to the conductor length. In alternative embodiments either sonic or light energy is applied to the test line for measurements. Thus it can be determined if the installed geogrid is in compliance with architectural plans, drawings or the like.
