US Patent:

6409478, Jun 25, 2002

Filed:

Feb 26, 1999

Appl. No.:

09/258833

Inventors:

William B. Carnes - Milwaukie OR
Milton K. Leonard - Lake Oswego OR
Robert B. Ray - Vancouver WA

Assignee:

Roper Holdings, Inc. - Wilmington DE

International Classification:

F04D 904

US Classification:

417200

Abstract:

A self-priming centrifugal pump including a supplementary vacuum pump and a float valve. The vacuum pump serves to draw liquid to the pump for priming and the float valve shut of flow to the vacuum pump when liquid reaches a predetermined level to prevent entry of liquid into the vacuum pump. In some embodiments the float valve includes an o-ring valve seal and the vacuum pump includes an oil delivery system to distribute oil from an oil reservoir to improve lubrication.

Assignee:

Roper Holdings, Inc. - Wilmington DE

International Classification:

F04D 2910

US Classification:

415112, 415231

Abstract:

A pump system, including an impeller and an impeller shaft, which has one end secured to the impeller and another end that may be coupled to a motor to drive the impeller. The pump system further includes a substantially liquid-proof barrier which has an opening through which the impeller shaft extends. The opening in the barrier is sealed with a shaft sealing system that includes a supply chamber fluidly coupled with a cavity. The cavity surrounds, and is at least partially bounded by, the impeller shaft. The shaft sealing system further includes a pressure mechanism that is configured to pressurize lubrication matter contained within the supply chamber and cavity, so as to inhibit liquid from passing along the impeller shaft through the cavity and thereby penetrating the liquid-proof barrier. The pressure mechanism is further configured to vary pressure of the lubrication matter based on atmospheric pressure surrounding the pump system.

Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

H01H 47/00
B41J 29/38

US Classification:

307125, 347 5

Abstract:

A mechanism of one embodiment of the invention is disclosed that disconnects an electronic device from a power source includes a user-actuable switch, an electronically controllable switch, and a feedback mechanism. The electronically controllable switch couples the power source to the electronic device. The feedback mechanism turns on and off the electronically controllable switch in response to actuation of the user-actuable switch.
