International Classification:

G10D 3/00

US Classification:

84290, 84193

Abstract:

The present invention is a hollow body stringed musical instrument that utilizes a low mass, soundboard having a 12 foot radius dome configuration. The soundboard is made of a three ply torsion box design utilizing a honeycomb substrate as the central core. Linear adjustable tuning braces are incorporated in the hollow body. The side and back of the instrument are also of a three ply construction having a closed cell, resilient polymer foam as the central layer. All structural braces are eliminated from the interior of the instrument's body.

Abstract:

The present invention is a hollow body stringed musical instrument that utilizes a low mass, soundboard having a 12 to 25 foot radius dome configuration. The soundboard is made of a three ply torsion box design utilizing a honeycomb stiffening layer as the central core. Linear adjustable tuning braces are incorporated in the hollow body. The side and back of the instrument are also of a three ply construction having a polymer ir inorganic foam as the central layer. (Preferably this will be a closed cell foam. ) The back also has a domed configuration with a 12 to 15 foot radius. All structural braces are eliminated from the interior of the instrument's body.

Abstract:

A composition and process for cleaning an aluminum-containing article is disclosed. The process comprises: contacting a debris-laden aluminum containing article with a composition at conditions effective to do at least one of the following: (1) remove at least a portion of the debris from the aluminum-containing article and (2) condition at least a portion of the debris for removal from the aluminum-containing article, the composition comprising water, at least one tartaric component selected from the group consisting of racemic tartaric acid, salts of racemic tartaric acid and mixtures thereof, at least one acidic component in an amount effective to increase the solubility of the tartaric component in the composition, and at least on surface active component; and recovering the aluminum-containing article having at least a portion of the debris removed therefrom.
