Patent CA-2277827-A1 (CA)
Title: Drywall corner finishing device
Inventor: JUDY RUSSELL E
IPC: E04F19/06
Filed: 1995-06-09
Abstract: A finishing device used to form a comer between two panels (804) of drywall has a flexible joint (100) extending along a predetermined axis. Two wings (102, 104) are connected to and extend outwardly in a diverging relation from the flexible joint (100) to form a corner having a adjustable angle. Each wing (102, 104) has a front surface (106), a rear surface (108), and an edge (110) distal from the flexible joint (100). This edge (110) abuts one of said drywall panels (804) and has a thickness approximately equal to the thickness of the drywall panel (804). A layer of primer (300) or adhesive laminate (400) is applied to the front surface (106) of the wings (102, 104) so that paint can bond to the front surface (106).   The finishing device is capable of forming both inside and outside corners. TO form inside corners, the finishing device bends along the flexible joint (100). TO form outside corners, strip (208, 210) parallel to the flexible joint (100) are removed from the rear surface (108) of the wings (102, 104) and the finishing device is folded along the opening thus created.

Title: Systeme de demande de connexion sans contact pour ordinateur
Inventor: GSTOEHL ANTON
IPC: G06F1/00
Filed: 1998-02-19
Abstract: L'invention concerne un système de demande de connexion pour ordinateur, qui comprend un système de transmission sans contact permettant de transmettre sans contact un code d'identification à un dispositif de détection de code. A cet effet, le dispositif de détection est monté dans un dispositif d'entrée/sortie d'ordinateur ou dans un tapis de souris et est en boucle dans une interface de l'ordinateur de manière qu'aucune autre interface de l'ordinateur n'ait à être occupée. Le système de demande de connexion comprend en outre un support de données sans contact et un dispositif de détection de code, de préférence une antenne d'émission/réception, raccordée à l'ordinateur et communiquant sans contact avec le support de données. Pour identifier l'utilisateur, le support de données sans contact qui se trouve au niveau du poignet est amené dans la zone d'influence de l'antenne, du fait qu'il est conduit à proximité de l'antenne. Le système de transmission incorporé dans le support de données est activé par le champ de l'antenne et émet de ce fait le code d'identification. L'antenne reçoit ensuite le signal de demande de connexion (code d'identification) qui est transmis à l'ordinateur.

Patent CA-2289485-A1 (CA)
Inventor: SHARP JAMES E
IPC: C22B15/00
Filed: 1998-05-15
Abstract: The subject invention pertains to processes for extraction of metals from sulfide mineral concentrates and for production of leaching reagents. In one embodiment, the processes of the subject invention utilize a substrate having a high external surface area.  In a specific embodiment, this substrate is a ring and pin polyethylene packing to which the concentrates can be bound. The packing provides high external surface area per unit volume over which the concentrates can be thinly coated. The high density of the packing allows high pulp densities to be achieved while leaving a large pore space, which provides relatively uninhibited flow of leach process solutions.

Patent CA-2292645-A1 (CA)
Inventor: KIM HOSEOB
IPC: G03F7/20
Filed: 1999-04-05
Abstract: L'invention se rapporte au traitement aux faisceaux d'électrons de tranches ou de masques. Selon l'invention, un repère est relié par couplage capacitif à la surface supérieure d'une couche de résine sus-jacente sur un substrat, formant ainsi un potentiel de tension à la surface de la couche de résine, directement par-dessus le repère d'alignement. Le repère d'alignement est directement connecté à un conducteur électrique qui produit une tension alternative sur ledit repère d'alignement, induite par capacitance à la surface de la couche de résine. En variante, le repère d'alignement est lui-même relié par couplage capacitif à une plaquette conductrice placée à la surface de fond du substrat semi-conducteur. On applique à la plaquette conductrice une tension alternative qui induit une charge dans le repère d'alignement, qui, par conséquent, induit par capacitance une charge à la surface de la couche de résine. Un faisceau d'électrons balayant la surface de la résine génère des électrons secondaires. Les électrons secondaires possèdent une énergie basse et sont influencés par le potentiel de tension créé à la surface de la couche de résine. Ainsi, la détection du signal d'électrons secondaires généré par le faisceau d'électrons permet de détecter le potentiel de tension à la surface de la couche de résine, par contraste avec les zones environnantes. Par conséquent, on détecte le repère d'alignement au moyen d'un faisceau d'électrons tel qu'un faisceau d'électrons à faible énergie produit, par exemple, par une microcolonne de faisceaux d'électrons, qui n'a pas assez d'énergie pour pénétrer dans la couche de résine.

Title: Tensioner for the header of a harvester
Inventor: MCCREDIE PAUL JOHN
IPC: A01D41/14
Filed: 2000-02-15
Abstract: A chain or belt tensioner is provided in a header for a harvester having a pair of rollers, each supported on separate pivot arms and engagable with the slack and taut strands of the chain or belt. The pivot arms are mounted about a common pivot and are spring biased into engagement with the chain or belt by a common spring. When the drive direction is reversed, the normally slack side of the chain becomes taut and assumes a straight-line position between the sprockets or sheaves. The pivot arms will rotate about the pivot and the pivot arm on the strand that has now become slack will rotate to tension the slack strand. The biasing spring coupled to the two pivot arms biases the rollers against the two strands of the chain and provides a fixed tensioning force on the chain that does not require adjustment.

The biofiltering system comprises a bed of peat overlying the effluent absorption area, the peat defining a biofiltering medium having a predetermined biofiltering capacity, and a fluid flow regulating unit for allowing the wastewater effluent to be treated to flow at a flow rate greater than the biofiltering capacity of the peat, while not exceeding a predetermined threshold value. The system further includes a predetermined number of spaced-apart, elongated distribution conduits arranged over the bed of peat and in fluid flow communication with the flow regulating unit, each distribution conduit having a plurality of discharge orifices spaced longitudinally therealong, for distributing the wastewater effluent through the bed of peat in a manner such that wastewater discharged from the distribution conduits through the orifices flows through the bed of peat at a flow rate no greater than the biofiltering capacity of the peat. The biofiltering system according to the invention enables one to efficiently treat large quantities of incoming wastewater irrespective of the flow rate thereof.

Abstract: A method of systematically cleaning and maintaining building sewage pipes is disclosed. The building drainage system consists a first conduit which collects waste water from one or more drains in an upper storey of the building, and a second conduit located in the basement of the building which is connected to the first conduit and receives the waste water from the first conduit. The method consists of first mechanically cleaning out any waste buildup in the second conduit, and then clearing the waste buildup from the first conduit by treating the first conduit with a biologically active solution. The biologically active solution is selected to break down the waste buildup from the first conduit. The mechanical cleaning step can be carried out by powerwashing.
