Filed:

Mar 16, 2000

Appl. No.:

09/526897

Inventors:

Claude T. Anderson - Forest Lake MN 55025
Michael G. Rieth - Woodbury MN 55125

International Classification:

G06F 1760

US Classification:

705 26, 705 37, 705 80

Abstract:

A computer-based method and system for executing an auction. The invention discloses a method for conducting an online auction in which a nonredeemable fee is collected from each auction participant to enter the bidder pool for a particular item. The collective nonredeemable fees from all bidders are then allocated to reduce the minimum bid required to purchase the item for the sellers asking price and to pay the transactional costs associated with the auction. Using this invention, a high value item can be purchased at very low cost to the high bidder, without the seller having to accept a reduced price for the item. Furthermore, this invention is amenable to a wide variety of auction systems because the computer-based auction and sale system can ensure the seller obtains their asking price for an item without requiring that the item be awarded to the high bidder.

International Classification:

E02B 904

US Classification:

405119, 405 80, 405 39, 405 40, 405 41

Abstract:

A flume for diurnally storing and releasing municipal sewage in its conveyance network of sewers and interceptor piping to reduce peak flow rates in a sewer system and the downstream wastewater treatment plant. The disclosed invention reduces peak flow rates without affecting flow rates below a selected threshold, maintaining minimum flow rates while storing wastewater in sewers and providing features that protect against sewer backups during high flows.

Filed:

Oct 7, 2004

Appl. No.:

10/960132

Inventors:

Michael Rieth - Woodbury MN, US
Claude Anderson - Arden Hills MN, US

International Classification:

C02F001/72

US Classification:

210758000, 210916000

Abstract:

The invention consists of a process to cost-effectively reduce or eliminate odors from wastewater treatment plant processes. The invention discloses the recycling of a portion of a wastewater treatment plant nitrified effluent, utilizing the dissolved oxygen and nitrate in the effluent to prevent the formation or reduce levels of sulfides and odourous organics in primary clarifiers. The process can be supplemented with conventional chemical treatment such as nitrate addition, and other process recycle streams such as incinerator scrubber water may also be used.

12/486802

Inventors:

Michael Rieth - Woodbury MN, US
Claude Anderson - Arden Hills MN, US

International Classification:

C05F 3/04

US Classification:

71 12

Abstract:

This invention is related to methods for the production of high phosphorus fertilizer products from waste products. In particular, the method describes the production of liquid and dry fertilizer products produced from the incineration of wastewater treatment sludges utilizing biological phosphorus removal (Bio-P). The fertilizers produced can be used interchangeably for commercial purposes either directly as a fertilizer product, or mixed with other conventional products to produce custom blended fertilizers for particular purposes.

Appl. No.:

13/182395

Inventors:

Claude Anderson - Arden Hills MN, US

International Classification:

F03D 7/06

US Classification:

416 1, 416 17

Abstract:

A vertical axis wind turbine having a rotor assembly within a support structure supporting a rotor assembly. A directional vane repositions a guide track to maintain a substantially fixed position relative to changes in the wind direction. A blade is rotatably connected to a strut extending from a rotatable shaft. The blade pitch is controllable with a guide pin positioned substantially near the trailing edge of the blade. The guide pin follows a guide track resulting in a blade pitch that may change as the blade rotates through a revolution. Multiple guide tracks may be used to change the blade pitch pattern at a given position as a result of varying operating conditions such as wind velocity. Using guide track pitch control, the drag and lift forces can be optimized for improved starting torque as well as improved lift and reduced drag under high wind velocity conditions.

International Classification:

E03F 100

US Classification:

137 1

Abstract:

A method and apparatus for diurnally storing and releasing municipal sewage in its conveyance network of sewers and interceptor piping to affect a reduction in peak energy demand and on-peak energy usage at the wastewater treatment plant, and, to reduce peak loadings to wastewater treatment plant clarifiers, aeration basins, channels and pumps, thereby improving plant performance and extending the wastewater treatment plant capacity. Utilization of the existing sewer system provides a way to obtain cost effective electrical cost reductions, flow equalization capacity, or an optimized combination thereof. With the disclosed invention it is possible to equalize wastewater flows, or alternatively to shift flow peaks from the on-peak electric rate periods to the off-peak electric rate periods providing less equalization.
