Patent CA-2329475-A1 (CA)
Title: Fast cycle psa with adsorbents sensitive to atmospheric humidity
Inventor: BABICKI MATTHEW
IPC: B01D53/26
Filed: 2000-12-11
Abstract: Disclosed embodiments address contaminant management, particularly water management, challenges that arise during production of desirably contaminant free product fluid in the operation of PSA equipment, particularly challenges that arise under intermittent operation of PSA equipment. One disclosed embodiment of a PSA apparatus includes a breather fluidly coupled to a feed end of an adsorber with a contaminant-sensitive adsorbent. The breather can be coupled to the feed end through a shutoff valve closed during production and open during shutdown. Other disclosed embodiments of the PSA  apparatus used particular sealing strategies for additional sealing of the apparatus or components thereof. For example, one embodiment comprises a buffer seal for receiving a buffer gas having a contaminant vapor content substantially the same as or less than a product gas produced by a pressure swing adsorption process over the adsorbers. The buffer chamber may have flushing circulation provided by delivered product flow. As a second example of sealing strategy, a parking seal can be used that typically is engaged when the apparatus is parked. Various seals can be used alone, or in combination with other contaminant management features. Embodiments of a method for reducing adsorbent degradation by contaminant adsorption while producing a product gas also are described comprising providing described embodiments of the PSA apparatus or system, and operating such PSA apparatus or system to produce a product gas. Various embodiments for operating a PSA apparatus and system during normal product delivery, shutdown, park and start up modes also are described.

Abstract: A hydrocarbon reservoir undergoing secondary recovery is subject to a first and then at least a second gravity gradient survey in which a gravity gradiometer takes gradient measurements on the surface above the reservoir to define successive data sets. The differences between the first and subsequent gravity gradient survey yields information as to sub-surface density changes consequent to displacement of the hydrocarbon and the replacement thereof by the driveout fluid including the position, morphology, and velocity of the interface between the hydrocarbon to be recovered and the driveout fluid.
Patent CA-2331907-A1 (CA)
Title: Self-regulating, axle-mounted electrical generation device
Inventor: MURRAY WAYNE H
IPC: H02K7/18
Filed: 2001-01-22
Abstract: A rail-car status-indicating assembly is provided for mounting to the axles of railcars. A solenoid and a magnet are part of the assembly installed each to one of a non-rotating structure and a rotating structure which co-rotates with the axle so that each time the solenoid enters the magnets field a current is induced. Preferably, a housing forms the rotating structure for protecting the inductive components. A bearing and pendulum are mounted within the housing to form a non-rotating structure. Magnetically induced co-rotation is eliminated by mounting of the electrical components to an offset pivoted structure. One form of low-power status device is light emitting diodes, electrically connected to the solenoid for repeated emission of light visible to oncoming motorists. Other embodiments include use of low power temperature sensors and the use of LEDs to transmit two or more status condition or via RF transceivers.  Alternatively, the housing forms the non-rotating pendulum structure and the axle rotates a rotary member bearing one of either the solenoid or magnet.
Patent CA-2334169-A1 (CA)
Title: Universal forms engine
Inventor: WOLFSTON JAMES H JR
IPC: G06F40/00
Filed: 1999-06-04
Abstract: A forms engine allows data sharing between customizable on-line forms, such as college admissions applications. Before applying, an applicant opens an account with a third party application servicer. After the applicant complet es an application for one institution, the data is saved in a data base and automatically populates fields in subsequent application forms. The form for  each institution is created from a form description file. Each form is brand ed for its institution and forms for different institutions differ in appearanc e and content so that the presence of the third party servicer is transparent to the applicant. The system is extensible without programming, allowing new applicant attributes to be readily incorporated into the system and allowing  the content and appearance of the application to be readily changed by changing the description file. The use of aliases for applicant attributes permits data to be readily shared between forms even though labelled and arranged differently on different forms. Information stored about each attribute allows the specification of data validation rules and data sharing  and grouping rules, as well as dependency rules that permit application page  content to depend on applicant's responses on a previous page.

Abstract: A hinge assembly for casement windows is shown and described. The hinge assembly includes a slide block for connection to the sash arm that includes a reinforcing plate that extends downward before extending upward and around the flange of the track overhang. A larger undercut portion is provided beneath the reinforcing plate for added clearance between the slide block and fasteners used to secure the track to the window sill. The hinge assembly also includes a pivot base which is pivotally connected to the shorter tie bar or toggle link. The position of the pivot base with respect to the track can be adjusted as a means for compensating for sash sag. An additional hole is also provided to provide new anchorage in the case of a sash sag adjustment or additional anchorage for use in high wind areas. The pivot base also includes a quick disconnect retainer disposed beneath the pivot base and between the pivot base and the track and thereby hidden from plain view. The short tie bar or toggle link is riveted to a pivot pin thereby eliminating the need for any rivet connection to the track. The pivot pin extends downward from the tie bar through the pivot base and is retained by the retainer which is disposed beneath the pivot base.
