US Patent:

6397549, Jun 4, 2002

Filed:

Jul 6, 2000

Appl. No.:

09/610288

Inventors:

Robert A. Baldwin - Phoenix AZ 85014

International Classification:

E04C 140

US Classification:

52596, 52422, 52437, 52605, 52607

Abstract:

A concrete-based building block has an attached wooden attachment layer on one or both exterior surfaces of the block that can receive and hold a penetrating fastener such as a nail, screw, staple, or the like. This allows surficial coverings such as wallboard, siding or other materials to be easily attached to a block wall made of the building blocks. The block includes substantially semi-cylindrical concave portions that form a cross-linked structure of channels when the blocks are assembled into a wall. Once the blocks have been stacked in place in a wall, grout or other suitable filling material is poured into the cross-linked structure of channels. When the filling material hardens, the blocks are locked together. Surficial covering materials may then be nailed, screwed, or stapled directly to the attachment layer of the blocks.

Abstract:

A building block has a cement-based attachment layer on one or both exterior surfaces of the block that can receive and hold a penetrating fastener such as a nail, screw, staple, or the like. This allows surficial coverings such as wallboard, siding or other materials to be easily attached to a block wall made of the building blocks. The block includes substantially semi-cylindrical concave portions that form a cross-linked structure of channels when the blocks are assembled into a wall.

10/872183

Inventors:

Robert Baldwin - Phoenix AZ, US

International Classification:

G06K009/36
G06F015/00
G09G005/02

US Classification:

382276000, 358001900, 345589000

Abstract:

A computer apparatus and method process a digital image according to a set of selected colors, and generate from the digital image a paint-by-number image. The set of selected colors may be manually selected one at a time by a user, or a predefined set of colors may be selected by a user. Predefined sets of colors may include commercially-available paint sets, crayon sets, colored marker sets, and colored pencil sets. In this manner, a user may take a digital image (such as a digital photograph of grandma or the family pet), select a particular paint or crayon set, and generate a paint-by-number picture of the digital image that is customized to the selected paint or crayon set. The resulting paint-by-number picture may include a legend that correlates the characters on the paint-by-number picture that represent color to the corresponding colors in the set of selected colors. The preferred embodiments also include a method for doing business that includes processing a customer-selected digital image according to a customer-selected color set, and outputting the resulting paint-by-number picture to the customer. Another method for doing business within the scope of the preferred embodiments is selling a product that defines a set of colors, such as a paint set or a crayon set, with software that includes the image processor of the preferred embodiments that allows generating paint-by-number pictures that are customized to the colors in the product.

US Classification:

Abstract:

A concrete-based building block has an integrally-formed wooden attachment layer on one or both exterior surfaces of the block that can receive and hold a penetrating fastener such as a nail, screw, staple, or the like. This allows surficial coverings such as wallboard, siding or other materials to be easily attached to a block wall made of the building blocks.
