US Patent:

20020162283, Nov 7, 2002

Filed:

May 1, 2001

Appl. No.:

09/845499

Inventors:

Jack Benson - Silver Spring MD, US

International Classification:

E04H012/34
B66C023/34

US Classification:

052/123100

Abstract:

An apparatus consisting of a self standing communications tower or a guy wire supported communications tower with such structural design as to allow raising the tower from ground level with an upper section raised up and a lower section inserted below. The apparatus structural design allows for a tie down to prevent toppling during the erection sequence. The erection apparatus enables raising the towers from the ground level by assembling and raising each section followed by assembling and raising the adjacent lower section until the tower is completely assembled. A tie down apparatus to secure the tower from toppling over during erection. The apparatus provides for more efficient fabrication and erection while increasing personnel safety.

Filed:

Nov 5, 1979

Appl. No.:

6/091281

Inventors:

Dale S. Gibbs - Midland MI
Jack H. Benson - Midland MI
Reet T. Fernandez - Midland MI

Assignee:

The Dow Chemical Company - Midland MI

International Classification:

C08K 505
C08K 513
C08G 1806

US Classification:

525455

Abstract:

A crosslinked vinylidene chloride polymer microgel powder is recovered from a latex and dispersed with moderate shear in a nonsolvent for vinylidene chloride polymers, such as a polyol used in the preparation of polyurethane materials. A dispersion of the powder and a polyol is eminently suited for use in the preparation of polyurethane foams to impart enhanced flame-retardancy and load-bearing properties thereto.

Assignee:

The Dow Chemical Company - Midland MI

International Classification:

C08J 7500
C08G 1806

US Classification:

524507

Abstract:

A vinylidene chloride polymer powder, having a second order transition temperature of at least about 50. degree. C. , is recovered from a latex and dispersed with moderate shear in a non-solvent for vinylidene chloride polymers, such as a polyol used in the preparation of polyurethane materials. A dispersion of the powder and a polyol is eminently suitable for use in the preparation of polyurethane foams to impart enhanced flame retardancy and load-bearing properties thereto.

Filed:

Apr 26, 1995

Appl. No.:

8/429496

International Classification:

B02C 1900

US Classification:

241 33

Abstract:

An apparatus of an elongated polygon-shaped vessel having a longitudinal axis, and an internal volume, wherein the elongated vessel is rotatably mounted about its longitudinal axis, and wherein optionally, the internal volume is divided into a plurality of transverse chambers having a polygonal cross-section shape, and can optionally be further divided into a plurality of longitudinal sections, an inlet for receiving material, and an outlet for removing material, is useful, for example, as a composter for municipal solid waste (MSW), source separated organic waste, yard waste, sewage sludge, and of organic hazardous waste, as a wet mill to reduce the sizes, mix, and screen materials, such as MSW, source separated organic waste, yard waste, sewage sludge, and organic hazardous waste, and as a rotating vessel, such as a cement kiln or ball mill.
