53782038, Jan 3, 1995

Filed:

Apr 2, 1991

Appl. No.:

7/680243

Inventors:

Ronald G. Baebel - Dallas TX

Assignee:

Ultra Polymer Sciences, Inc. - Dallas TX

International Classification:

F16H 5512

US Classification:

474 96

Abstract:

An improved mechanical donut and donut assembly in which donuts made of plastic materials are formed in segments that facilitate installation, removal and/or replacement for manufacture and maintenance. The donuts of the preferred embodiments are made of urethanes, especially polyurethane, while fastening members such as threaded bolts are made of nylon. The relative characteristics of the urethanes and nylon are such as to facilitate a self-tapping feature for the nylon bolt.

Appl. No.:

8/794415

Inventors:

Ronald G. Baebel - Houston TX

International Classification:

B05C 512

US Classification:

427136

Abstract:

A method for controlling both fugitive bauxite dust and sodium hydroxide contamination generated by the waste disposal of bauxite tailings from aluminum processing plants comprising using magnesium chloride or sodium chloride or mixtures thereof on the surface of the disposal pits, which are also known as mud lakes. Preferably, a solution of magnesium chloride is applied to the surface of a dry or partially dry mud lake. The magnesium chloride neutralizes the sodium hydroxide on the surface, forms a hard crust that covers the fine bauxite particles and also inhibits the migration of unreacted sodium hydroxide to the surface.

Appl. No.:

7/741241

Inventors:

Ronald G. Baebel - Dallas TX

Assignee:

Ultra Polymer Sciences, Inc. - Dallas TX

International Classification:

B60P 100

US Classification:

298 1B

Abstract:

An improved particulate handler that includes one or more elastic sheets that are particularly effective in facilitating the easy and complete removal of particulate from transporters or containers such as railroad cars, dump trucks, chutes and the like. The combination of the elastic sheets and supporting walls overcomes the problem with sticking of particulates to the interior surfaces and facilitates smooth and easy movement and/or removal under the influence of gravity and changes in tensile stresses and stretch that develop in the sheets during loading, unloading and conveying.
