Patent CA-2339095-C (CA)
Inventor: CROTTAZ OLIVIER
IPC: C25C3/12

Granted: 2008-07-15
Abstract: L'invention concerne une anode pour une cellule d'extraction électrolytique de l'aluminium, cette anode comprenant un corps ou une couche en alliage fer-nickel dont la surface est oxydée de manière à former une couche extérieure adhésive en fer à base d'oxyde, et en particulier d'hématite. La surface de cette couche est active d'un point de vue électrochimique, et permet donc une oxydation des ions oxygène ainsi qu'une réduction de la diffusion de l'oxygène de cette surface active d'un point de vue électrochimique vers le corps ou la couche en alliage fer-nickel. Les dimensions de cette anode peuvent rester stables pendant toute la durée d'utilisation de la cellule, une quantité suffisante d'alumine et de fer dissous étant conservée dans l'électrolyte afin de prévenir toute dissolution de la couche d'oxyde extérieure de l'anode ou de chaque anode, la température de fonctionnement de l'électrolyte limitant par ailleurs la dissolution du fer dans cet électrolyte.

Abstract: An outboard motor has an engine and a mounting case disposed below and connected to the engine. The mounting case has a depression opening upward. The opening is covered by a cover to form a coolant chamber. An exhaust passage passes through the coolant chamber and commnicates with an exhaust expansion chamber formed by an extension case to be positioned below the mounting case. The coolant chamber is covered by the cover so that a small mating surface is formed with the coolant chamber independently of an engine mating surface of the mounting case. This simplifies the structure of the mounting case.

Title: Buffer tank for polymer melts, in particular cellulose solutions
Inventor: ECKER FRIEDRICH
IPC: B29C48/475
Filed: 2000-11-20
Granted: 2006-03-14
Abstract: The present invention relates to a buffer tank as is substantially used for ensuring a constant supply of the spinning machine with a polymer melt in spinning machines. To this end the buffer tank is provided with a compensation chamber whose volume is variable in response to a pressure prevailing in the polymer melt and to a volume flow variation. The polymer melt flows from a polymer melt entry opening to a polymer melt exit opening through the compensation chamber. It is the object of the present invention to make the flow through the compensation chamber uniform. The residence time of the polymer melt in the compensation chamber shall thereby be prevented from having a wide range, the latter resulting in an irregular quality of the yarns produced by the spinning machine because of the time-dependent, mechanical and chemical properties of the polymer melt. To achieve said object, the compensation chamber is provided for flow optimization with at least one flow guiding element projecting into the flow of the polymer melt, which is smaller than the flow cross-section of the compensation chamber and by which the velocity profile in the direction of flow through the compensation chamber is made uniform at least in sections.

Abstract: A method of assembling pipe joints in a pipe string allows the circumferential orientation of a first pipe (13) in the pipe string to be determined relative to a second pipe (13) in the pipe string. Each pipe joint has a coupling member (15) and at least one pin member (13), the pin member (13) being threadingly connected to the coupling member (15) to create the pipe joint (11).  Threads (21, 29) are created for the pin member (13) and the coupling member (15) of each joint, and each pin member and coupling member is marked with an alignment mark (35, 37). The threads (21) for each pin member are created so that they are identical to the threads on the other pin members in the pipe string. This is done by gaging the overall rotational capacity of each pin member with a coupling marking gage (43) and adjusting a thread depth as needed.

Abstract: A multi-carrier information transceiver that exhibits robustness against radio frequency interference (RFI) signals present in the communications channel.  The transceiver includes a RFI mitigation technique that operates not only during the steady state operation of the transceiver but also during the training stage of the transceiver. That requires dynamically modifying the training signals when the presence of RFI is detected. The modification of the training signals facilitates the estimation of RFI, improving the performance of the multi-carrier transceiver.

Title: Ocular plug for punctal and intracanalicular implants
Inventor: ZHOU STEPHEN Q
IPC: A61L27/00
Filed: 2000-08-04
Granted: 2009-05-26
Abstract: An ocular plug design and method of insertion is described for the treatment of dry eye. This ocular plug is a narrow rod-like cylinder of appropriate diameter, which is tapered at one end, for insertion into an ocular channel. The plug is prepared from either (or both) of two specific classes of polymeric materials having both viscous and elastic properties. The first class of polymeric materials have a glass transition temperature (Tg) at or below human body temperature (37 ~C). The second class of polymeric material s have a melting temperature (Tm) at or below human body temperature (37 ~C). The plug is stored in a frozen, rigid, elongated state prior to insertion in to an ocular channel. Once inserted into an ocular channel, the smart plug responds to an increase in temperature, due to the surrounding physiochemica l environment, whereby it becomes soft and the plug subsequently expands to adapt to the size and shape of the patient's punctum or canaliculum. Once th e plug expands to the size of the particular ocular channel, the plug is met with a resistance from the surrounding tissue. At this point, expansion of t he plug ceases and the plug can effectively block tear drainage through either ocular channel.

Abstract: The illustrative embodiment of the present invention provides a method of recording object associations using a location system. Object locations are determined based on signals generated from object identifiers linked to the objects and forwarded to an electronic device interfaced with a network. The origin of the signal is calculated by a location determining module based on a variety of factors including the known position of the receivers receiving the signal, the historical recorded position of the object, the characteristics of the receivers receiving the signal (i.e. the range), the strength of the received signal, the type of signal, and whether or not the signal was repeated. Once the location of the object has been determined, the locating determining module consults a database to determine associations between the located object and other objects or specified locations based on the other objects proximity to the located object. Once an association is determined, it is stored and the duration of the association is subsequently recorded. The data from the identified associations may then be leveraged in a number of ways as input data for a variety of applications, such as billing software, equipment utilization software, asset management software, and automatic event generation software.
