Patent CA-2264498-A1 (CA)
Title: Process using staggered bypassing of reaction zones for increased capacity
Inventor: PETERS KENNETH D
IPC: C10G35/24
Filed: 1999-03-04
Abstract: The operation of multistage catalytic hydrocarbon conversion system in which hydrocarbons flow serially through at least two reaction zones is improved by using staggered by-passing of a portion of the change to each zone such that the first zone processes only a first portion of the feed and the second zone processes the remaining portion of the feed and at least a portion of the effluent from the first zone. Where three reaction zones are used, processing of the effluent stream from the first reaction zone is split between the second and third reaction zones so that a portion of the charge to each zone always is directed around the zone and processed in the next reaction zone. One portion of the effluent stream is combined with hydrocarbons that bypassed the first reaction zone, and the combined stream is passed to the second reaction zone. The other portion of the first reaction zone effluent stream and at least a portion of the effluent stream of the second reaction zone are passed to the third reaction zone. This invention is applicable to processes where the first and second reaction zones are susceptible to pinning in that this invention decreases the mass flow through the first and second reaction zones while nevertheless maintaining high hydrocarbon conversion capacity.

Patent CA-2290199-A1 (CA)
Title: Fuel tank vent system with orifice
Inventor: PEOTTER BENJAMIN G
IPC: B60K15/035
Filed: 1999-11-22
Abstract: A fuel tank has a void air space when the tank is filled through a filler tube that upstands from a reservoir.      The reservoir has a baffle that depends from a top wall of the reservoir. Fuel entering the reservoir from the filler tube fills the reservoir up to the level of the lowermost edge of the baffle. Further filling of the tank causes the fuel level to rise in the filler tube. However, a void space is created because air and fuel vapor are trapped in the reservoir on the opposite side of the baffle as the filler tube, which prevents overfilling by an operator. A vent system connects the void space with the top end of the filler tube. Hydrostatic pressure exerted by the fuel on the air and fuel vapor in the void space expels the air and fuel vapor through the vent system to the filler tube, causing the fuel level to rise in the void space and simultaneously to lower in the filler tube. Eventually all the air and fuel vapor are expelled, and the fuel level in the filler tube is then at a minimum level. The invention is capable of venting a fuel tank that is tilted in operation such that a void space is present in the reservoir.
