Patent CA-2224543-A1 (CA)
Inventor: CADORETTE MARIO
IPC: E06B9/36
Filed: 1997-12-09
Abstract: A vertical blind having a head-rail, a plurality of carriers slidable in the head-rail for movement between open and closed positions. A respective vane is suspended from each of the carriers and a pivot rod is rotatably mounted in the head-rail and extending through the carriers for rotating the vanes. A control assembly comprises a controller securely affixed to a first carrier. The controller includes a control body slidably mounted in the head-rail, a first gear member disposed within the carrier body and rotationally coupled to the pivot rod and slidable thereon, and a control shaft rotatably mounted in the control body and extending through a base portion of the control body. The control shaft includes a second gear member operatively engaged with the first gear member, so that rotation of the control shaft causes rotation of the pivot rod via rotation of the second gear member and the first gear member. The control shaft further includes means for operatively coupling a wand to the control shaft, whereby the control shaft can be rotated by rotating the wand, and the control assembly can be slid within the head-rail by pulling the wand. The control shaft is mounted at an angle within the control body so that, when the vanes are rotated towards their closed position, the wand is concealed behind a vane suspended from the first carrier.

Title: Improved method and apparatus for injection of tubing into wells
Inventor: GIPSON THOMAS C
IPC: E21B19/22
Filed: 1997-12-24
Abstract: An improved apparatus and method for injecting and retrieving a length of coiled tubing and storing the tubing on a storage spool.  An injector reel is pivotally mounted on  a  frame  such  that  coiled  tubing may be  angularly injected  to  shallow,  horizontal  wells.    A  hold-down assembly is provided to individually adjust the pressure applied to the coiled tubing as it is injected into or retrieved from a well.   The positioning of the injector reel and the storage spool in the injecting mode ensures a greater degree of wrapping of the coiled tubing around the injector reel to improve the control of the injection and retraction of the tubing.  A vertically and horizontally adjustable storage spool cradle enables the operator to vary the width and diameter of the storage spools used in the apparatus.

Abstract: Les fissures, au niveau du sous-sol des résidences, dans les murs en béton engendrent beaucoup d'inconvénients pour les résidents tels que l'infiltration des eaux, l'inondation du sous-sol, la non jouissance des lieux, etc.... Dans de tels cas, la réparation des fissures s'impose. Plusieurs méthodes existent pour remédier à ce problème entre autres l'injection d'époxy dans la fissure. Cependant, cette méthode de réparation n'est pas sans incidence à court et à moyen terme dans la mesure où l'évolution de la fissure n'est pas arrêtée. Autour de la fissure, il y a une concentration de contraintes de différents types. La fissure dans le mur est une zone de faiblesse ce qui se manifeste par la croissance de la fissure suivant différentes directions. La présente invention est de stabiliser la fissure pour éviter son évolution.

Abstract: A method and system for continuous incineration of solid waste, directed to reducing formation of pathogens (such as dioxins) during incineration by inducing rapid combustion in an oxygen-rich environment. Waste may be shredded first. Waste is then dispersed widely across a first combustion chamber (150) in which it undergoes incineration into ash and gas. Alternative embodiments for continuous removal of hot ash are disclosed. Gas is encouraged to travel a spiral path into a second combustion chamber (170), in which further incineration occurs. Gas travels through the second combustion chamber (170) also in a spiral path, and is cooled in a quench tube (180). An evacuator means (190), advantageously a large fan, draws air through the system continuously during combustion encouraging flow of waste through the system and replenishing oxygen available for rapid combustion.

Abstract: The folding, and accumulation in configurations simulating a booklet, of flexible sheets (such as paper sheets) is accomplished in a simple, straight-forward, yet effective manner. A movable bar (14) is pivotally mounted at a first end (23) adjacent a cutter (11) from which it receives paper sheets (A).  A plurality of first pulleys (15, 16, 17) having a circumferential periphery with a concave substantially V-shape are mounted by the movable bar (14) and cooperate with a second plurality of pulleys (19, 20, 21) on a stationary V-shaped bar (18). The second pulleys (19, 20, 21) have convex substantially V-shaped circumferential peripheries with a groove for receipt for a circular cross section conveyor belt (38) which extends between the sets of pulleys and drives sheets (A) for folding between them. At the discharge end of the folder is a downwardly sloping convex substantially V-shaped bar (44) which cooperates with a guide (50) (having a concave V-shape) and an automatically movable stop (46). After a plurality of folded paper sheets in a configuration simulating a booklet are collected, the stop (46) is released and they are transmitted to a binder (43).

Title: Spectral decomposition for seismic interpretation
Inventor: GRIDLEY JAMES M
IPC: G01V1/28
Filed: 1997-11-12
Abstract: The present invention is directed generally toward a method of processing seismic data so as to provide improved quantification and visualization of subtle seismic thin bed tuning effects and other sorts of lateral rock discontinuties A reflection from a thin bed has a characteristic expression in the frequency domain that is indicative of the thickness of the bed: the reflection has a periodic sequence of notches in its amplitude spectrum, said notches being spaced a distance apart that is inversely proportional to the temporal thickness of the thin bed.    Further, this characteristic expression may be used to track thin bed reflections through a 3-D volume and estimate their thicknesses and lateral extent. The usefulness of this invention is enhanced by a novel method of frequency domain whitening that emphasizes the geologic information present within the spectrum. Although the present invention is preferentially applied to a 3-D seismic volume, it is alternatively applied to any collection of spatially related seismic traces.

Title: Method for overload control in a multiple access system for communications networks
Inventor: CHUAH MOOI CHOO
IPC: H04L69/14
Filed: 1998-10-08
Abstract: In the method for overload control in a wireless communications network employing On-Demand Multiple Access Fair Queuing, if the downlink/uplink buffer occupancy of the network has exceeded a high threshold, the base station determines if this is caused by a specific remote host or by a group of remote hosts. If caused by a specific remote host, the base station normally sends a flow control signal to the remote host to prevent it from sending more data, but may alternatively elect todisconnect other remotes if the remote experiencing bad performance is of a higher priority. The base station may additionally reduce the bandwidth shares allocated to any remote that have indicated tolerance for a variable allocated bandwidth. If the measured frame error rates for many remote hosts are increasing, then the base station may elect to disconnect those remote hosts that permit service interruption in order that more bandwidth may be allocated to the remaining users. If a majority of all associated remote hosts experience high uplink frame error rates, the base station may instead send a signal to a wireless hub which can coordinate the actions of other access points. Short packets queued up for so long at the base station that they exceed the time-to-live value allocated will be thrown away. The base station may also or alternatively elect to disconnect some users of a lower priority or redirect them to other nearby base stations that have a lower load. In a particular embodiment, an uplink Frame Error Rate (FER), an average uplink bit rate, a burstiness factor of uplink traffic, and a packet loss rate are measured at the base station for each remote host. Similarly, a downlink Frame Error Rate is measured at each remote host andthen each FER is sent to the base station. If an overload condition exits, connections with a Frame Error Rate that has exceeded a threshold for a specified time and that have indicated that their connections can be interrupted are disconnected. Othercombinations of the possible actions are suitable, with the exact combination being determined by the base station depending on the particular congestion conditions observed in the network.
