Patent CA-2314637-C (CA)

IPC: E01H1/08

Abstract: A closed-loop Regenerative® air sweeper is provided. The sweeper includes a "dustless" mechanism having first and second chambers, into the first chamber of which is directed a portion of the air stream from a pressure conduit associated with a pickup head of the sweeper. Particles of debris are separated by cyclone separators and thereafter by membrane filters after which substantially clean air is discharged to atmosphere. Air entrained particles separated by the cyclone separators and the cartridge filters are returned to a vacuum side of the pickup head thereby maintaining substantially closed-loop air flow of the sweeper. Clean air is controllably exhausted to atmosphere by flue vanes which can be selectively moved under pressure differential sensing means associated with the cyclone separator. The pressure in the two air chambers is also sensed with the read-out thereof being in an instrument panel to permit an operator to monitor and diagnose the system. Pulses of high pressure air are utilized to clean the membrane filter and a pop-off valve serves as an emergency vent to atmosphere under undesired high pressure within the second chamber of the housing. An extremely important aspect of the present invention is that achieved by creating and maintaining a substantially negative pressure at and across the pickup head. The latter is achieved by assuring that the air drawn into the pickup head is approximately a nominal ten percent (10%) and the clean air discharged to atmosphere is maintained at substantially the same nominal ten percent (10%) through appropriately operating a valve under the control of a pressure differential sensor which measures pressure drop across the cyclone separators.

Title: Method and apparatus for signaling path restoration information in a mesh network
Inventor: ZIMA CATHY HELEN
IPC: H04L69/40
Filed: 2001-02-16
Granted: 2005-04-12
Abstract: A method and apparatus are disclosed for monitoring and signaling a path restoration using pre-computed restoration paths following a detected fault on a primary service path in a communications network. A fault occurring inside the restorable portion of a network in heterogeneous or multiple network environments can be distinguished from faults occurring outside the restorable network in accordance with the ANSI Tandem Connection Maintenance standard, T1.105.05-1994. Path restoration is activated only when a fault causing path failure occurs inside the restorable portion of the network. Each conforming node in the restorable portion of the network has the necessary monitoring, signaling and cross-connect functionality and databases to participate actively in real time restoration. Additional non-conforming network elements can be positioned between the restoration nodes without preventing path restoration. With the signaling architecture of the present invention, when an end-node detects a path failure caused by an in-network fault, it formulates a signaling message for restoring the failed path. The restoration signaling message is thereafter relayed from one node to another in the overhead or payload of signaling paths that occupy the same bandwidth that is subsequently used by the restoration path. Once a signaling message is transmitted to an adjacent node in the overhead or payload of a particular signaling path, the node that transmitted the message makes a cross-connect that replaces the signaling path with a segment of the restoration path whose set-up was requested in the transmitted signaling message.

Abstract: The reactivity of a number of p-methylphenyl thioglycoside (STol) donors which are either fully protected or have one hydroxyl group exposed has been quantitatively determined by HPLC in conjunction with the development of a broadly applicable approach for a facile one-pot synthesis of oligosaccharides. The influence on reactivity of the structural effects of different monosaccharide cores and different protecting groups on each glycoside donor is characterized and quantified. In addition, a correlation between glycosyl donor reactivity and the chemical shift of the anomeric proton by 1H NMR has been established. A database of thioglycosides as glycosyl donors has been created using this reactivity data. The utility is demonstrated by the easy and rapid one-pot assembly of various linear and branched oligosaccharide structures. In addition, a computer program as been described for use as a database search tool and guide for the selection of building blocks for the one-pot assembly of a desired oligosaccharide or a library of individual oligosaccharides.

Title: Automated seismic fault detection and picking
Inventor: LUCAS WILLIAM A
IPC: G01V1/28
Filed: 1999-08-12
Granted: 2003-12-16
Abstract: A computer implemented method and apparatus is disclosed for automatically picking faults (24) in a recorded 3D seismic trace data volume (20). The method employs test planes, which are mathematically inserted into the same data volume (20) to approximate dip and azimuth of a potential fault plane surface (33). A large number of data points, which are selected points on the seismic traces, are defined within the seismic volume (20), such that each test plane positioned in the seismic volume (20) contains data points corresponding to at least a significant portion of traces. The method then determines a factor for each data point which is representative of the probability that the data point resides on a fault plane (33). This probability is based on planar discontinuity and average amplitude difference between corresponding traces in adjacent parallel test planes, and the method selects locations, in an x, y grid, of a strip of locations having high probability of residing on a fault surface (94). The strip of the selected locations is smoothed to a line and used to construct fault lineaments displays in seismic sections or time slices. The fault lineaments are stored in a computer data file (24) and conventional, stratigraphically enhanced, or other seismic data enhanced for seismic attributes is merged with the fault lineament files to create consolidated displays to aid interpretation of the data volume (33).

Title: A method and a circuit for recovering a digital data signal and a clock from a received data signal
Inventor: FINSETH NIELS CHRISTIAN
IPC: H03L7/087
Filed: 1999-11-23
Granted: 2006-06-06
Abstract: By application of a method for recovering a digital data signal (D out) and a clock signal (Ck out) from a received data signal (D in) consisting of a number of successive bits, a clock signal is produced from the received data signal by means of a resonator circuit (5). The recovered data signal is produced by sampling the received data signal with the recovered clock signal. The received data signal and the recovered clock signal are phase locked to each other so that the received data signal is sampled approximately in the centre of every bit. By phase locking the two signals to each other immediately prior to the sampling, the effect of varying time delays to which the two signals have been subjected individually on their way through the circuit is neutralised, and every sampling may be performed precisely within the very short time during which the data signal is stable.
