Filed:

Jun 23, 1998

Appl. No.:

9/103102

Inventors:

William Dixon - Lambertville NJ

International Classification:

B21D 508

US Classification:

72181

Abstract:

The present invention is a tool for manually altering the angle of a sheetrock corner bead strip from approximately 90. degree. to an angle larger than 90. degree. The tool includes a main frame having a base and opposing side walls. The main frame is adapted to receive and hold axles for at least two spreader wheels and at least two corner holder wheels. The spreader wheels with axles are mounted in series alignment with one another for rotation within the main frame and the corner holder wheels with axles are also mounted in series for rotation within the main frame. The spreader wheels and the corner holder wheels are all located in a single plane. In a preferred embodiment, the spreader wheels have walls which form truncated V-shaped sides for maintaining a predetermined angle. In another preferred embodiment, the predetermined angle is approximately 120. degree. or approximately 135. degree.

Monsanto Company - St. Louis MO

International Classification:

A01N 936

US Classification:

71 87

Abstract:

alpha. -cyano-. alpha. -dialkylphosphonato acetanilides are prepared by reacting an. alpha. -cyano-. alpha. -dialkylphosphonate carbanion with an aromatic isocyanate or isothiocyanate. The said carbanion may be generated in situ by the reaction of an alkali metal or reactive compound thereof with an. alpha. -cyano-. alpha. -dialkylphosphonato acetanilide. Compounds within the scope of the invention described herein are pesticidally active, e. g. , as herbicides.

Appl. No.:

William Dixon - Lambertville NJ

International Classification:

B24D 1500
B24D 1504

US Classification:

51358

Abstract:

The present invention is directed toward flexible embossed supportive backings for coated abrasives, which are used with "sanding" tools. The supportive backing is made from a flexible elastomeric material embossed on one side with a predetermined pattern. The embossment pattern incudes an uninterrupted narrow border along the edges that lay perpendicular to the primary of travel during use, a plurality of narrow grooves within the border which disrupt the surface area of the elastomeric material, and lines of severance that partially separate the edges of the material from its main body. The surface acts as the supportive backing for a coated abrasive as it is worked over a roughened surface. The grooves created by the embossment pattern allow the coated abrasive to deform as it encounters high points on a roughened surface, which allows the abrasive to surround the contours of the roughened surface and greatly increases the efficiency of the coated abrasive. The grooves created by the embossment minimizes the work dust trapped between the coated abrasive and the supportive surface, which minimizes high points and uneven results.
