Patent CA-2333650-A1 (CA)
Title: Fan shroud with integrated reservoirs
Inventor: CHAPMAN TIMOTHY W
IPC: F01P5/06
Filed: 1999-07-21
Abstract: A fan shroud for use with a cooling fan adjacent to the radiator for a water cooled internal combustion engine includes a generally central opening for directing flow of air to or from a radiator. The fan shroud includes at least one integral chamber for storage of other liquids typically used with a vehicle which may be under pressure. To facilitate handling pressure, the storage chamber includes a plurality of individual storage modules which are interconnected by a plurality of fluid flow channels so that the total storage capacity of the chamber is the sum of the storage capacity of the modules and interconnecting fluid flow channels. The modules and channels are made by bringing the front and back walls of a blow molded fan shroud into contact with each other to define there between channels and modules. Advantageously, the shroud comprises several such chambers and may be used to house engine coolant, power steering fluid or other fluids. In addition, the fan shroud can include chambers for storing fluids which are not necessarily under pressure such as windshield washer fluid and the like.
Patent CA-2337488-A1 (CA)
Title: Vibrator
Inventor: GOUGHNOUR R ROBERT
IPC: E02D7/18
Filed: 2001-02-16
Abstract: A vibrator for vibrating an object. The vibrator is provided with a rotary housing mounted on a frame for rotation about an axis. Multiple rotary eccentric masses are mounted at equally spaced intervals in this housing about the housing axis and they are mounted for rotation on their respective axes which are parallel to the housing axis. A rotary drive is connected for simultaneously rotating the eccentric masses in the same direction and in synchronism such that all masses are directed simultaneously to their inner most and their outer most positions of movement relative to the housing axis. This generates a force moment about the housing axis which rotatably oscillates the housing.

Inventor: FLETCHER DAVID E
IPC: H01M8/0612
Filed: 2001-07-25
Abstract: Hydrogen and carbon are produced by decomposing natural gas or methane in a field of barrier discharge non-thermal plasma. The apparatus for carrying out this process has two concentric elongated electrodes, one internal and one external, and a dielectric barrier between them, so arranged that there is a suitable gap between the internal electrode and the barrier. A high voltage pulser is connected to the electrodes and, when powered, creates the barrier discharge non-thermal plasma in the gas passing through the gap, thus decomposing this gas into its components, namely hydrogen and carbon.

Patent CA-2359534-A1 (CA)
Inventor: LUBY MICHAEL G
IPC: H04L12/18
Filed: 2000-09-15
Abstract: An encoder uses an input file of data and a key to produce a group of output symbols. A group of output symbols with key I is generated by determining a weight, W(I), for the group of output symbols to be generated, selecting W(I) of the input symbols associated with the group according to a function of I, and generating the output symbol values B(I) from a predetermined value function F(I) of the selected W(I) input symbols. An encoder can be called repeatedly to generate multiple groups of output symbols or multiple output symbols. The groups of output symbols are generally independent of each other, and an unbounded number (subject to the resolution of I) can be generated, if needed. A decoder receives some or all of the output symbols generated. The number of output symbols needed to decode an input file is equal to, or slightly greater than, the number of input symbols comprising the file, assuming that input symbols and output symbols represent the same number of bits of data.

On fabrique le dispositif optique à l'aide de guide d'ondes ou de fibres conservant la polarisation mais ce dispositif est conçu pour être utilisé dans des systèmes mettant en oeuvre des fibres ne conservant pas la polarisation. Ledit diviseur/mélangeur de faisceaux de polarisation sert également de base à un isolateur/propagateur et à un régulateur de polarisation (10). Ledit régulateur de polarisation (10) convertit un signal lumineux polarisé de manière aléatoire en un signal ayant un état de polarisation connu et déterminé.
