Filed:

Aug 16, 2000

Appl. No.:

09/639719

Inventors:

John T Richter - Seneca SC

Assignee:

Square D Company - Palatine IL

International Classification:

H05K 720

US Classification:

361695, 622592, 454184

Abstract:

A multi-level thermal management system and method are provided for cooling a plurality of vertically spaced electrical components, including a lower electrical component and an upper electrical component. The system includes a rigid support securing the upper electrical component in a fixed position above the lower electrical component. A duct, having an upper end and a lower end, an inlet defined in the lower end of the duct and an outlet defined in the upper end of the duct, is mounted adjacent to the upper electrical component with the inlet being located above the lower electrical component to direct air heated by the lower electrical component through the duct without substantially contacting the upper electrical component.

Abstract:

In one embodiment, a cleaning cart system of the invention includes a reservoir assembly, an upwardly extending handle releasably connectable to the reservoir assembly, and at least two modular cleaning bins. The reservoir assembly includes a liquid reservoir and an integral wheeled chassis. The liquid reservoir includes a circumferential sidewall and an integral top wall, with the top wall including a plurality of openings. The two modular cleaning bins may be: positioned within the liquid reservoir; positioned on the liquid reservoir top wall with a leg of one bin positioned in one of the top-wall openings, and with a leg of the other bin positioned in another of the top-wall plurality of openings; and alternatively releasably interconnected to one another in a side-by-side orientation, with one of the bins supported on the upwardly extending handle by one or more of a plurality of handle brackets.

13/477040

Inventors:

Robert S. Robinson - Hamilton OH, US
David W. Lloyd - Hamilton OH, US
Robert W. Kyde - Fairfield OH, US
John T. Richter - Hamilton OH, US

International Classification:

A47L 7/00

US Classification:

15320

Abstract:

An embodiment of the cleaning and floor care system has a reservoir assembly and a wet/dry vacuum assembly. The reservoir assembly has a wheeled chassis and an integral reservoir. The reservoir has a circumferential sidewall and an upper end. The reservoir defines an interior space for holding a fresh cleaning liquid; and the reservoir upper end defines an opening. The reservoir assembly further has a spigot fluidly connected to the reservoir interior space, with the spigot having a valve adjustable between a fully open and a fully closed position. The vacuum assembly has a recovery tank and a motor assembly. The vacuum assembly is removably positionable on top of the reservoir, and is transportable on the reservoir. Each of the reservoir assembly and the vacuum assembly is operable both when the vacuum assembly is positioned on top of the reservoir, and when the vacuum assembly is separated from the reservoir.

International Classification:

A47L 11/30

US Classification:

15320

Abstract:

A multi-functional cleaning and floor care system may have: a fresh liquid reservoir; a vacuum assembly including a vacuum recovery tank and a vacuum motor assembly; a wheeled chassis configured to support at least one of the fresh liquid reservoir and the vacuum recovery tank; and a spigot fluidly connected to the fresh liquid reservoir, with the spigot adjustable between a fully open position and a fully closed position. The system also may have: a liquid spreader assembly connected to at least one of the fresh liquid reservoir, the vacuum assembly, and the wheeled chassis, with the liquid spreader assembly including a frame and a spreader pad; and a squeegee head assembly connected to at least one of the fresh liquid reservoir, the vacuum assembly, and the wheeled chassis, with the squeegee head assembly fluidly connectable to the vacuum recovery tank.

US Classification:

44280

Abstract:

Methods for enhancing the flow behavior and stability of hydrothermally treated slurry fuels. A mechanical high-shear dispersion and homogenization device is used to shear the slurry fuel. Other improvements include blending the carbonaceous material with a form of coal to reduce or eliminate the flocculation of the slurry, and maintaining the temperature of the hydrothermal treatment between approximately 300. degree. to 350. degree.
