Patent CA-2310060-A1 (CA)
Title: Apparatus to facilitate rail transit by motor vehicles
Inventor: SPATA STEPHEN C
IPC: B61D15/00
Filed: 1998-11-23
Abstract: An apparatus for facilitating the travel of a motor vehicle (2), designed for roadway travel, upon railways has the capacity to be towed to the rail site by the motor vehicle. The apparatus has a platform (12) having at least one rotatable axle of roadway tires (40) attached thereto. In the deployed position, the roadway wheels allow the apparatus to be towed similarly to a trailer. When the apparatus is properly positioned over a railroad crossing, the rotatable wheels are drawn back to a retraced position, the apparatus is lowered so that rail wheels, mounted to the platform, engage the rails exactly as other rail vehicles. A removable ramp (14) allows the motor vehicle to mount the platform. The wheels (5, 6) of the motor vehicle engage either one or two sets of rollers (51, 52) disposed upon the platform. After the motor vehicle is properly secured, the motor vehicle can be engaged to drive the rollers, with the power delivered to the rollers being transmitted to the train wheels to supply the necessary locomotion. To accommodate various motor vehicles of differing offsets between the driven axles (3, 4), the distance between the two sets of rollers may be adjusted, and each may receive rotational power from one axle of the vehicle and transmit that energy to one of the sets of train wheels of the apparatus to propel the apparatus down the railways, and thus either end of the apparatus may serve as the forward end of the apparatus when it is upon a railway.

Abstract: A release brake (1) for a window covering (4, 28) of the type having a roller (2) about which either a window covering material or lift cords (10, 12) are wound as a stationary member (20), a movable member in the shape of a drum (15), and a hub (17).      In one embodiment particularly useful for a roller shade, the hub (17) is fixed and the surrounding movable member (15) can be restrained or released by a coil spring (23) encircling the hub (17). In another embodiment the member which surrounds the hub (17) is fixed and the hub (17) can be restrained or released by a coil spring (23) encircling the hub. The spring (23) is sized and positioned so that the spring (23) will press against the outside surface of the hub ( 17) when in a relaxed condition to restain the hub (17) or sized and positioned to press against the inside surface of the movable member when in a related condition to restain that member. The tangs (25, 27) of the spring (23) are moved relative to one another to increase the diameter of the spring (23) which releases the hub (17) and allows it to rotate freely or to decrease the diameter of the spring (23) which releases the movable member (15) and allows it to rotate freely.

IPC: C01B13/02
Filed: 2001-01-05
Abstract: The invention maintains a nearly constant cycle pressure ratio along with a balancing of the adsorbent vessel effluents in a pressure swing adsorption process. The invention monitors cycle pressure ratio and subsequently alters the cycle step times and flows to sustain its value, thereby maximizing plant performance and avoiding unnecessary shutdowns.      Maintaining a nearly constant pressure ratio assures that the plant production is optimized and that power consumption is minimized. The balancing of the adsorbent vessel effluents, using the corresponding waste purities, is used to further improve plant production.

Patent CA-2342838-A1 (CA)
Inventor: LIZARDI PAUL M
IPC: C12Q1/6853
Filed: 1999-09-15
Abstract: Disclosed are reagents and a method for efficient in vitro molecular cloning  of nucleic acid molecules of interest. Because the method is entirely in vitro, it can be automated and scaled-up in ways that are not possible in ce ll- based molecular cloning. The method involves insertion of a nucleic acid molecule of interest in a linear vector to form a circular vector where one strand is continuous and the other strand is discontinuous. The continuous strand of the circular vector is then amplified by rolling circle replicatio n, amplifying the inserted nucleic acid molecule in the process. The amplification is rapid and efficient since it involves a single, isothermic reaction that replicates the vector sequences exponentially. The amplificati on process is amenable to automation where multiple reactions are carried out simultaneously in a small area. The amplified nucleic acid can be used for a ny purpose and in any manner that nucleic acid cloned or amplified by known methods can be used. This includes sequencing, probing, restriction analysis , subcloning, transcription, hybridization or denaturation analysis, further amplified, and storage for future use or analysis.

Title: Method for bi-level customization of programs
Inventor: LEEDS JORDAN
IPC: G06Q10/00
Filed: 2001-06-08
Abstract: A system and method for establishing a customized visual presentation, for on-site use to foster worksite wellness, requires that a provider compile a plurality of information modules. Each module pertains to an occupational descriptor, such as supervisory, clerical, strenuous or non-strenuous manual labor, custodial, or other, and within each descriptor there is an occupational program with subject areas, such as safety, work hazards, environmental illnesses, worksite injuries, and performance motivation. In operation, an intermediary obtains modules from the provider and presents these modules for selective accessibility at a worksite. An individual end user at the worksite can then customize a selected occupational program with personal data and retrieve digitized excerpts from the provider, through the intermediary over an Internet connection. The digitized excerpts are thus presented in conformance with and in accordance with the personal data, the occupation program and the information module to establish the visual presentation at the worksite.
