Filed:

Jul 29, 2008

Appl. No.:

12/220892

Inventors:

Charles Bolta - Boulder CO, US
Dennis Clark - Boulder CO, US

International Classification:

H05B 35/00
H01J 9/00

US Classification:

315182, 445 26

Abstract:

A switchable compact fluorescent lamp with an L.E.D. added to the center of the top of the compact fluorescent lamp plastic electronic encasement housing. The L.E.D. can be switched on with the fluorescent on or switched to be on by itself with the fluorescent off. The lamp can also be switched to a battery and or capacitor power backup for the L.E.D. when the power goes off.

Appl. No.:

13/185363

Inventors:

Dennis Clark - Erie CO, US
Scott Anderson - Lafayette CO, US

Assignee:

Earthcore Worldwide, Inc. - Lafayette CO

International Classification:

E04C 3/00
C09J 5/00
E04C 2/20

US Classification:

523094, 52834, 156305, 52847

Abstract:

The present invention relates to the construction arts, in particular a new implementation for a framing member or structural support apparatus for bearing the loads required for walls, roofs, ceilings, and floors. Further a formed insulated layer with enhanced adhesion characteristics provides a thermal break within the framing member serves to increase the insulation value and enhance the structural value of the apparatus.

Appl. No.:

13/585815

Inventors:

Scott C. Anderson - Lafayette CO, US
Dennis W. Clark - Erie CO, US

Assignee:

EARTHCORE WORLDWIDE, INC. - Lafayette CO

International Classification:

B32B 37/00

US Classification:

156494

Abstract:

The present invention relates to a novel device to manufacture polyurethane foam boards used in structurally insulated panel known as insulated building material press. The press enables the application of pressure across a large area while foaming and curing polyurethane under pressure, curing glue or otherwise bonding materials into a finished product. The press uses a simple principle to distribute pressure evenly across the platens avoiding the need for heavy and expensive parts used in the construction of building material presses of the prior art.

International Classification:

B32B 3/22
B32B 5/18
B32B 37/14
B32B 3/10

US Classification:

428138, 428201, 428194, 2989732

Abstract:

An insulated wall panel comprising of two outer layers, an insulating foam core, and a spacer within the foam core which holds the panel spacing and retains the foam during foam introduction and expansion in the cavity and remains as part of the panel. The panel has no thermal bridging between the outer layers and is manufactured with reduced need of rigid mold forms. The final effect after pouring becomes a monolithic foam core of substantially consistent material and provides a superior product to using dissimilar retained spacing materials.
