Us Patents

Pump Connector System

US Patent:
2006022, Oct 12, 2006
Filed:
Apr 6, 2005
Appl. No.:
11/100219
Inventors:
John Kochan - Naperville IL, US
International Classification:
G08B 21/00
US Classification:
340612000
Abstract:
A single pump control unit can be coupled to first and second float switches and a pump for purposes of removing fluid from a region such as a sump. A supplemental set of contacts can be provided to couple an alarm indicating signal to a remote alarm. An alarm state can also be transmitted wirelessly.

Pump Control With Multiple Rechargeable Battery Docking Stations

US Patent:
2007018, Aug 16, 2007
Filed:
Jan 16, 2007
Appl. No.:
11/623377
Inventors:
John Kochan - Naperville IL, US
International Classification:
H02J 7/00
US Classification:
320107000
Abstract:
A backup pump control unit can incorporate ports to receive rechargeable batteries such as lithium ion, nickel cadmium or nickel metal hydride batteries. Multiple units can be coupled together to increase the available, stored electrical energy. In the absence of AC-type input power, the batteries can energize a backup pump.

Pump Control Unit With Decelerometer Switch

US Patent:
2009020, Aug 13, 2009
Filed:
Feb 6, 2009
Appl. No.:
12/366840
Inventors:
John R. Kochan - Naperville IL, US
International Classification:
H01L 41/00
US Classification:
327516
Abstract:
A pump control unit incorporates an accelerometer as a sensor. Responsive to outputs from the sensor, electrical load driving signals can be provided to energize a pump motor to reduce a fluid level in an enclosure.

Sump System Having Timed Switching Of Plural Pumps

US Patent:
5449274, Sep 12, 1995
Filed:
Mar 24, 1994
Appl. No.:
8/217420
Inventors:
John Kochan - Naperville IL
Assignee:
Metropolitan Pump Company - Romeoville IL
International Classification:
F04B 4106
F04B 49025
US Classification:
417 8
Abstract:
An electronic pump selector system uses a programmable processor to select one of a plurality of pumps to be energized in response to an appropriate feedback signal from the selected pump. A current limited feedback circuit is incorporated which provides a varying voltage in response to a level switch associated with a selected pump indicating a high fluid level. In response to the voltage feedback signal, the selected pump is energized for a predetermined period of time. Subsequently, another pump is selected. The next selected pump is energized also for a predetermined period of time in response to a varying voltage feedback signal therefrom. The next pump is then selected and the sequence continued.

Connector System For Use With Electrically Operable Pumps

US Patent:
5071370, Dec 10, 1991
Filed:
Dec 4, 1990
Appl. No.:
7/621802
Inventors:
John R. Kochan - Naperville IL
Assignee:
Metropolitan Pump Company - Romeoville IL
International Classification:
H01R 1300
US Classification:
439620
Abstract:
A two part electrical connector system is provided for easily connecting the plug of an electrical device having two or more independently operable switches to a source of electrical energy. Each of the switches terminates in a two-part electrical connector formed as a plug and a receptacle. The members of the connector system can be coupled to the plug and receptacle portions of the switch terminating electrical connectors respectively. The interconnected assembly can be coupled to the source of electrical energy. The electrical plug of the associated device can then be engaged with the connector system. As one or the other of the independently operable switches responds to a predetermined condition electrical energy is coupled from the source, via the connector system and the responding switch, to the device energizing same.

Variable Speed Pump System With A Hydropneumatic Buffer/Pressure Tank

US Patent:
5707211, Jan 13, 1998
Filed:
Apr 25, 1995
Appl. No.:
8/428501
Inventors:
John R. Kochan - Naperville IL
Assignee:
Metropolitan Industries, Inc. - Romeoville IL
International Classification:
F04B 4900
US Classification:
417 38
Abstract:
A fluid pressure control system which is usable to control pressure in a fluid distribution system includes a variable speed drive coupled to a pump. A hydropneumatic tank is coupled to the distribution system. In normal operation, the variable speed drive actuates the pump so as to maintain pressure in the system. Under low flow conditions, a control unit, using the variable speed drive energizes the pump so as to pump fluid into and pressurize the hydropneumatic tank. The control unit then shuts off the pump. Pressure is maintained in the system, until a predetermined, lower, set point is reached as a result of pressure in the hydropneumatic tank.
