US Patent:

7702999, Apr 20, 2010

Filed:

Nov 27, 2002

Appl. No.:

10/306093

Inventors:

Douglas Sperr - Phoenix AZ, US
Scott Wessels - Phoenix AZ, US

Assignee:

DC Future LLC - Phoenix AZ

International Classification:

G06F 17/00

US Classification:

715222, 715203, 715221, 715223, 709203

Abstract:

A system and method for managing information over a network (, FIG. ) enables a user, at a client computer () to access and modify information accessible to a server (). A user can create (FIG. ) a new manageable entity (e. g. , a project), which results in storage of entity-specific and non-specific information (FIG. ) in a database (, FIG. ). In addition, a user can create or edit (FIG. ) various forms, which can be associated with one or more manageable entities. Information describing the form (FIG. ) is then maintained by the system. The form can then be used to enter or modify data associated with the manageable entity.

Appl. No.:

6/295638

Inventors:

Charles J. Sperr - Scottsdale AZ
Douglas C. Sperr - Scottsdale AZ

International Classification:

B01D 5000

US Classification:

55257R

Abstract:

A shroud, including a shield placed on either side of an evaporation pad, increases the length of travel air transit time within the pad. Pressurized water, emitted in jets from a plurality of orifices spaced along a manifold, is directed against a diffuser for dissipation and dissemination to the upper edge of the pad. The pad is wetted intermittently as the result of a timer controlling distribution of the water. An auxiliary reservoir, in combination with relocatable pump, inlet valve and pad frames, provide for alternate downdraft as side draft operation. An elongate, arcuate baffle downstream of the evaporative pad alters the direction of the air stream to flow in a substantially opposite direction.

International Classification:

F28D 300

US Classification:

62171

Abstract:

An improved evaporative cooler contains a first pump for supplying cooling liquid to the evaporative pads and a second pump for draining liquid in the sump pan through a drain/overflow pipe. Both pumps are coupled to an electronic control mechanism which activates the first pump for a first predetermined period of time within each successive second predetermined period of time (e. g. the first 2. 5 minutes of every successive 10 minute period). The control mechanism causes the second pump to drain the sump pan through the drain/overflow pipe for a third predetermined period of time following the first occurence of the first predetermined period of time (e. g. for 5. 0 minutes after the first 2. 5 minute wetting cycle). This draining process occurs only once each time the evaporative cooler is turned on.
