Title: Apparatus for the treatment of crankcase emissions materials in a positive crankcase ventilation system
Inventor: WINTER FRANK
IPC: B01D47/02
Filed: 1999-10-15
Abstract: An apparatus for the treatment of gases in a positive crankcase ventilation (PCV) system, in an internal combustion engine, is provided with a housing defining a gas treatment chamber. At least one gas filtering medium is disposed in the treatment chamber, and the gases from the engine crankcase are passed through the gas filtering medium in the treatment chamber, before the gases are routed into the air intake portion of the engine. In addition, the gases, after passage through the gas filtering medium, are passed through an ionization device.
Patent CA-2371066-A1 (CA)
Inventor: STENSTROM HELGE
IPC: H03F1/52
Filed: 2000-04-19
Abstract: L'invention porte sur un amplificateur de type différentiel tel qu'un comparateur ou amplificateur opérationnel possédant deux terminaux (1, 3) d'entrée formés par des terminaux d'entrée de base, et amplifiant des transistors (T1, T2) de type npn. Les collecteurs des transistors d'entrée sont raccordés à une tension d'alimentation (V¿CC?) par un circuit à miroir de courant (T4, T5). Les émetteurs des transistors d'entrée sont raccordés par un transistor (T3) alors qu'un générateur de courant est raccordé à une autre tension d'alimentation (V¿EE?) proche d'un potentiel de la masse. La jonction base-émetteur des transistors d'entrée est protégée par des transistors (T6, T7) qui sont raccordés comme des diodes, les émetteurs et les bases étant raccordés entre eux. La jonction pn effective des transistors de protection forme ensuite la jonction entre la base et le collecteur qui a normalement une tension de claquage élevée, et forme la jonction pn entre la base et l'émetteur. On obtient ainsi une protection des terminaux d'entrée de l'amplificateur qui peut être réalisée de manière simple dans des circuits intégrés, par exemple. Les transistors de protection sont conçus pratiquement de la même manière que les transistors d'entrée et ont pratiquement les mêmes propriétés électriques que ceux-ci.
Patent CA-2371081-A1 (CA)
Inventor: JOU YU-CHEUN
IPC: H04L27/26
Filed: 2000-04-21
Abstract: A method and apparatus for transmitting broadcast informa-tion in a multi-carrier communication system. The Sync Channel of the multi-carrier system is transmitted a 1.25 MHz channel bandwidth (i.e., over a single carrier), and to specify the pre-ferred channels for the Sync Channel transmission instead of the preferred channels for the entire multi-carrier system. The Sync Channel Message will carry the additional information to indi-cating the center frequency of a multi-carrier system within a reserved set of frequency bands and indicating the frequency of a single carrier system in the reserved set of frequency bands.    Con-sidering the A block of the PCS band again, the preferred channels for Sync Channel transmission can be selected as channels 75, 150 and 225. This selection ensures that one of the preferred channels will always be used by any multi-carrier system regardless of the location of its center channel.

Patent CA-2408519-A1 (CA)
Inventor: GROVES MICHAEL THOMAS
IPC: F03G7/10
Filed: 2002-10-29
Abstract: Abstract A weighted, cement wheel need not descend below or ascend upward, from the surface that a said cement wheel is stationed on, in order to produce a transfer of weight energy from the weight of the said cement wheel, to that of acquired compression from the said weight of the cement wheel. By rolling a cement wheel on top of a tube of fluid that has a maximum area of expansion, the said tube will expands to its maximized width and shape by the pressure of forced fluid being pushed forward through the tube by the compressing weight of the advancing cement wheel. By the acquired pressure within the tube, the shape of the tube will expand outward and upward before the advancing point of weight contact made by an advancing, weighted, cement wheel. It is the tube of fluid that expands upward to be then compressed by weight and it is not the wheel that must descend to transfer its weight into a form of energy. Horizontal compression is not applicable to laws of physics, which does not contain the peripherals or boundaries of its motion.
