US Patent:

7337554, Mar 4, 2008

Filed:

Oct 17, 2005

Appl. No.:

11/251714

Inventors:

Robert William Erickson - Minneapolis MN, US

International Classification:

F26B 7/00

US Classification:

34396

Abstract:

A technique for end-grain creation is employed for obtaining rapid and uniform drying of lumber while simultaneously reducing warp. The stability-kerfing responsible for the improved drying of the lumber decreases the edgewise bending strength by less than ten percent, a loss readily recovered due to the ability of stability-kerfing to achieve lower and more uniform moisture contents than those realized in the contemporary drying of lumber. The improved moisture condition provided by the stability-kerfing also fosters future dimensional stability at the time of entry into the marketing stream compared to that for contemporary lumber. The required stability-kerfing is easily accomplished by the specialized implementation of existing saw equipment and associated technology into the contemporary processing lines.

Appl. No.:

11/100710

Inventors:

Robert W. Erickson - Minneapolis MN, US

International Classification:

F26B 19/00

US Classification:

34396, 34518, 34381, 34 90, 34210, 34218, 100 50, 52641, 52 7912, 144347, 2972841, 2972844, 705 14, 264255, 264135

Abstract:

The present invention relates to an apparatus and processing method for drying lumber, for example two-by-four studs in an environment in a kiln in a manner to avoid warping, including crook, bow, cup and twist. The lumber pieces are stacked in a normal manner with stickers for providing air flow between courses of the lumber pieces, and the stack is dried while a horizontal force is provided to the respective courses of lumber in the stack to hold the individual pieces of lumber in edge to edge contact throughout the drying, equalizing, conditioning and cooling process for first drying of lumber, redrying of lumber or in a treatment process for removing warp from previously dried lumber. A vertical force comprising a weight or other force generating device can be also applied to the stack of lumber to augment the overall reduction in warpage if so evidenced.

Appl. No.:

13/958707

Inventors:

Robert Allen Erickson - Minneapolis MN, US

International Classification:

B62K 21/02

US Classification:

280279, 298971

Abstract:

A bicycle apparatus with interchangeable front fork is disclosed. The bicycle comprises a frame and a quick release assembly for securing the removable front fork attachment assembly to the bicycle frame's head tube. The interchangeable front fork attachment assembly and quick release assembly allows for the quick interchanging of front fork with varying attachments which utilize different methods to achieve motion.

US Patent:

Filed:

Dec 23, 1993

Appl. No.:

8/173351

Inventors:

Robert W. Erickson - Minneapolis MN

Assignee:

Regents of The University of Minnesota - Minneapolis MN

International Classification:

E04C 336

US Classification:

527363

Abstract:

A hollow light weight pole like structure suitable for use as a utility pole, column or log building member is made of a plurality of wood strips glued edge to edge forming a hollow interior core, with at least one layer of high strength veneer material glued to the exterior of the wood strips with the veneer grain running parallel to the length. The layer of veneer increases the strength, distributes bending stresses uniformly, provides greater decay resistance than ordinary glued hollow poles, and increases the service life. The veneer can be made in several layers forming a continuous overwrap without longitudinally extending gaps that expose the interior wood strips to weather or splitting.
