US Patent:

7018532, Mar 28, 2006

Filed:

Jan 27, 2004

Appl. No.:

10/764474

Inventors:

Michael J. Kaufman - Boswell PA, US

International Classification:

C02F 1/52
C02F 7/00

US Classification:

210205, 210206, 210219, 210154, 366337

Abstract:

Contaminated water is chemically treated and aerated while being gravity fed through a trough. A series of slats are positioned in the trough to interrupt the flow and induce mixing and aeration. An array of aeration edges is removably installed over the slats. A holder for containing chemical treatment matter therein is positioned adjacent each slat. The aeration edges consist of upper and lower plates stacked one on top of the other. Each plate is provided with horizontal fingers extending in a direction downstream relative to the flow direction of the treated water. Each finger terminates in a baffle, which baffle is positioned substantially perpendicular to its finger.

Appl. No.:

10/917448

Inventors:

Michael Kaufman - Boswell PA, US

International Classification:

F03B 13/00
H02P 9/04

US Classification:

290054000

Abstract:

The waterwheel powered air delivery device is a system for powering an air compressor, aerator, or other device that moves air from power produced by a waterwheel without the necessity of providing electricity from an outside power source or the intermediate production of electricity from the waterwheel. The waterwheel may be an overshot, undershot or sideshot waterwheel. The device being powered may be an air compressor, aerator, or other air delivery device having an air pump that may be of the diaphragm, piston, rotary vane, rotary screw or other type. Preferably the air produced by the waterwheel and air delivery device is used for aeration of wastewater, although the delivery device may be used for other purposes, e.g., ventilation, power, etc.

US Patent:

Filed:

Mar 12, 1979

Appl. No.:

6/019669

Inventors:

Michael J. Kaufman - Boswell PA

International Classification:

B65G 4722

US Classification:

198493

Abstract:

A pump for spraying an anti-freezing liquid on a conveyor belt exposed to freezing temperatures is controlled by an electric circuit containing a timer, a relay provided with a normally open switch, and a normally open thermostat that closes to start the timer when the ambient temperature falls below a given low temperature. The relay is connected in series with the timer switch and the thermostat to close the relay switch when both the timer switch and the thermostat are closed, whereby the pump will be operated until the timer times out or the thermostat reopens. If desired, the relay can be omitted.

US Patent:

Filed:

Aug 26, 1998

Appl. No.:

9/140664

Inventors:

Michael J. Kaufman - Boswell PA

International Classification:

G05D 1100

US Classification:

137 99

Abstract:

The invention is a water wheel supplying energy to a pump. The pump will typically be used to apply chemical treatments to the water stream. Some examples of chemicals to be added are acids or bases to bring the pH to an acceptable level, precipitation aids for suspending metal out of water, coagulants to aid in filtering dissolved solids out of water, flocculants to aid in filtering dissolved ions out of water, chlorine, or coloring to prevent growth of algae.
