Patent CA-2218579-C (CA)
Inventor: GUERRA LAWRENCE E
IPC: F16H7/08
Filed: 1997-10-17
Granted: 2003-07-08
Abstract: A belt tensioning system is provided for an appliance having a tub driven by an endless loop drive belt connected to a motor that is movable with respect to a tub housing surrounding the tub. The belt tensioning system includes a rib extending from the tub housing, a pivotal cam washer having a pivot axis and an eccentrically curved cam profile edge with a series of arcuately spaced contact points thereon for engaging the ribs on the tub housing. The cam washer is pivotally mounted to the motor along the pivot axis and loosenably secured against rotation about the pivot axis and with respect to the motor. Normally, one of the contact points engages the rib so as to establish an offset distance between the rib and the motor, and thereby a tension on the drive means. When the cam is loosened, the motor can be moved with respect to the tub housing and the cam washer can be pivoted into the rib until the rib rests against a new contact point on the cam profile edge to establish a new offset distance between the motor and rib so that a new tension is applied to the drive belt. The tension on the drive belt can be adjusted by moving the motor with respect to the tub housing until the desired belt tension is achieved. Rotating the cam means with respect to the motor until the cam profile engages the rib on the tub housing sets the desired belt tension. Then the cam means can be secured against rotation with respect to the motor such that the motor is fixed in position relative to the tub housing.

Abstract: Procédé et dispositif servant à déterminer la force d'un signal, indépendamment du débit de données du signal, dans un récepteur recevant des signaux depuis un émetteur à débit variable. Le signal d'arrivée est composé d'une série de blocs. Chaque bloc est composé de plusieurs groupes de commande de puissance contenant des données. Le nombre de ces groupes contenant des données à l'intérieur de chaque bloc dépend du débit de données inconnu. La position des groupes de commande de puissance à l'intérieur du bloc est pseudo-aléatoire. La force d'un signal d'arrivée, dont le débit de données est inconnu, est déterminée en fonction d'un ensemble actif de groupes de commande de puissance à l'intérieur d'un bloc. L'ensemble actif de groupes de commande de puissance contient des données indépendantes du débit de données inconnu. On peut utiliser l'information de force de signal afin d'indiquer que la force du signal est suffisante pour continuer à effectuer le traitement de signal.

Abstract: L'invention porte sur des procédés permettant d'améliorer la production de vaccins antiviraux dans une culture cellulaire animale. Ces procédés reposent sur la manipulation des taux, dans les cellules, de certaines activités antivirales induites par un interféron, notamment, de ceux de la kinase (PKR) dépendante d'ARN double brin et de la 2'-5' oligo-adénylate synthétase (synthétase 2-5A). Dans des cultures cellulaires déficitaires en PKR ou en synthétase 2-5A, on accroît de plusieurs ordres de grandeur la production du virus par rapport à celle de cultures cellulaires dont les taux cellulaires de ces protéines sont normaux, ce qui les rend des plus aptes à la production de vaccins antiviraux.

Title: Strand orientation sensing
Inventor: ENS JOHN E
IPC: G06T7/00
Filed: 1996-08-20
Granted: 2007-09-11
Abstract: The orientation of strands relative to a selected axis is determined by analyzing a digitized grey scale image to select edge pixels therefrom that may define the edges of strands segmenting the image into a plurality of subimages and processing one of the subimages by defining pixel lines merging the pixel lines to form lines segments and culling selected one of the lines in the subimage. The subimage is then combined to co-terminus other of the subimages to form a combined subimage which is processed in the same manner by merging pixel lines to form lines and culling selected line in the combined subimage. This process is repeated by combining further subimages and processing until substantially all of the image has been processed to provide the plurality of strand lines defining strand edges and then determining the orientation of the strand lines relative to the axis.

Title: Apparatus and method for extracting and replacing buried pipe
Inventor: NIKIFORUK NICK
IPC: F16L55/165
Filed: 1998-08-21
Granted: 2002-04-16
Abstract: A pipe/pulling frame is fitted to the tool end of a movable boom of an excavator, preferably visa a quick-attach coupling. The boom first positions the frame in and out of the pit and then secondly holds the frame against twisting movement in the pipe-extraction pit during pulling, thereby obviating the need to provide shoring and other bracing. The frame comprises an actuator and a single reaction plate. The actuator pulls a segmented cable which extends through the pipe while the reaction plate structure bears against the pit wall. The actuator is further operable also to push a stuck pipe, for which the reaction structure is moved to the opposing end of the frame. A swivel is preferably fitted between the tool end and frame to allow the excavator to be positioned independent of the frame. An abutment member at the distal end of the old pipe is replaceable with a ground- reaming tubular pipe for pushing the trailing end of the old pipe and pulling the leading end of a new pipe. The quick-attach coupling at the tool end accepts an excavation bucket to dig the pits, the frame for pulling the pipe, and a ripper tooth to rapidly pull lengths of old pipe from the ground once the force needed falls off.

Granted: 2008-06-10
Abstract: A vehicle headlamp having a light shield that does not outgas under normal lamp operation is disclosed. The vehicle headlamp uses a light shield with an interior surface with a rough, black ceramic coating. The ceramic surface absorbs almost all the visible light shone on it. The surface is highly resistant to the heat generated by the light absorption, and the roughness breaks up visible light images in any small amount of reflected light. The ceramic material does not outgas or deteriorate so as to leave a film on the other lamp elements.

Granted: 2007-04-03
Abstract: This invention relates to rail anchorages that are used with all rails, but is particularly concerned with adjustable rail anchorages, which allow rail alignment to be adjusted, and which are installed on rails used by cranes. To reduce this rail movement and to help limit vertical uplift of the rail, pressure is applied to the rail flange by resilient material attached to the part of the rail anchorage that overhangs the rail flange. The object of this invention is to provide support to the resilient material in a way that its length can be increased from the bonded surface or outside of the pocket in which it is installed. The invention allows for a greater variation in rail size and rail elevation that can be accommodated with one rail anchorage type and differing lengths of the resilient material.

Title: Wall panel assembly with airtight joint
Inventor: MECOZZI WALTER P
IPC: A47B96/00
Filed: 1999-11-01
Granted: 2007-10-02
Abstract: A wall panel assembly with a sealed joint. The sealed joint is virtually airtight even in an enclosure having an ambient air pressure substantially greater than the air pressure outside the enclosure, such as an air handling cabinet. Each joint is comprised of two abutting looped joint edges in combination with a Y-shaped seal. The looped joint edge provides added structural rigidity to the panels, and the enlarged looped ends on the joint edges enclose and protect the seal therebetween from exposure to the elements. The seal itself not only withstands positive internal air pressure but is actually improved thereby. Abutting joint edges of adjacent wall panels create a narrow channel for receiving the longitudinal flange portion of the seal, and a broader V- shaped channel to receive the enlarged body portion of the seal. In this way, the body portion of the seal is seated in a channel so that internal pressure exerted against the seal will cause the seal to appressingly engage the channel. Thus, increased internal air pressure improves the sealed joint rather than compromising it. The seal can be provided with a longitudinal slit for receiving the edge of internal divider panels. Adjacent wall panels are joined by fasteners intersecting the outwardly extending looped portions of the joint edges. In this way, the fasteners are accessible from the outside, and the integrity of the seal is preserved.
