Title: Compresseur et procede d'approvisionnement d'un moteur a combustion interne en carburant gazeux sous haute pression
Inventor: DOUVILLE BRAD
IPC: F17C5/06
Filed: 1998-12-21
Abstract: L'invention concerne un procédé et un appareil d'approvisionnement du moteur à combustion interne d'un véhicule en carburant gazeux sous haute pression en provenance d'un réservoir. En particulier, l'invention concerne un système d'approvisionnement en carburant avec trois composants principaux: le réservoir, le compresseur et un accumulateur. Des conduits de carburant relient chaque composant directement aux deux autres composants. Le compresseur comprend une pluralité de chambres de compression et une des chambres de compression peut être contournée lorsque le compresseur fonctionne en un mode de basse capacité, selon la pression dans le réservoir. Le compresseur fonctionne en continu. Lorsqu'il n'est pas nécessaire de comprimer le carburant, le compresseur fonctionne à vide et les orifices respectifs d'admission et de sortie des chambres de compression sont reliés par des conduits de carburant, ce qui empêche le carburant d'être comprimé. Le chargement du mécanisme d'actionnement du compresseur est équilibré dans tous les modes de fonctionnement.

Title: Communication system using a multiplex signal carrying an auxiliary signal
Inventor: GRUTTER HENDRIKUS JOHANNES
IPC: H04J3/00
Filed: 1999-10-27
Abstract: In a transmitting node (3) in a transmission system, a plurality of source signals are multiplexed by a multiplexer (34) into a multiplex signal. The multiplex signal is transmitted to a receiving node (5) where it is demultiplexed in the source signals. The multiplex signal comprises a plurality of packets having a flag field, a length field, a connection ID field and a data field. The flag field can be present to enable the receiver to find the beginning of the packet or to carry non-urgent control signals. According to the present invention, the length of the flag field is dependent on the aggregate bitrate of the source signals, making it possible that more source signals can be transmitted over the transmission link under heavy traffic conditions.

Patent CA-2321358-A1 (CA)
Inventor: BENSON DALE E
IPC: H02K11/26
Filed: 2000-09-29
Abstract: A method of reducing failure of an alternator due to voltage spikes. A first step involves providing a voltage control resistor which automatically adjusts to the voltage applied to it until a preset voltage threshold is reached. A second step involves connecting the voltage control resistor to a rotor of the alternator. Input into the voltage control resistor comes from a positively charged pole of the rotor and output from the voltage control resistor comes to a negatively charged pole of the rotor. Any voltage spikes which exceed the preset voltage threshold are transferred from the positively charged pole of the rotor to the negatively charged pole of the rotor.

Patent CA-2323339-A1 (CA)
Title: Structural reinforcement member and method of utilizing the same to reinforce a product
Inventor: BROWN GORDON L JR
IPC: E04C2/04
Filed: 2000-10-16
Abstract: A reinforcing grid which advantageously includes fibers of both a first type and a second type is provided. The first type of fibers have a strength sufficient to reinforce the hardenable structural material, such as concrete, after hardening. The first type of fibers also have a higher resistance to degradation in the hardenable material than the second type of fibers. As such, the first type of fibers will continue to reinforce the hardened material in the event the fibers of the second type become corroded in the hardened material. Consequently, a less expensive type of fiber can be used as the second type of fiber and can corrode in the hardenable material without concern for the strength of the hardened structural product. According to one embodiment, the first type of fibers comprises carbon fibers and the second type of fibers comprises glass fibers.

Patent CA-2326432-A1 (CA)
Title: Safety system for a projectile fuse
Inventor: SHAPHYR SHALOM
IPC: F42C15/24
Filed: 1999-04-06
Abstract: The invention provides a safety system for a small arms projectile in which an initiating device is impacted by a firing member in order to detonate a main explosive charge. The system requires the firing member to be retained in a safe position in relation to the initiating device by at least two independent mechanisms. The firing member is initially supported in a forward position, in which it assists in holding the initiator device in a safe condition, and is caused to move rearwardly, through inertia, when the projectile is fired, destroying one of the retaining mechanisms and allowing the initiator device to adopt a primed position in which it can be activated by the firing member which at this time is retained by the other retaining mechanism which is automatically released when the projectile is in flight. The initiator device may, when held in its safe condition, be skewed with respect to the main explosive charge and may incorporate or support a shield disposed, in the safe condition, between the initiator device and the main explosive charge.
