US Patent:

50551124, Oct 8, 1991

Filed:

Oct 30, 1989

Appl. No.:

7/428997

Inventors:

Michael P. Duncan - Lockport IL
Alexander M. Kulinowski - St. Louis MO

Assignee:

Ethyl Petroleum Additives, Inc. - St. Louis MO

International Classification:

C10L 118
C10L 1000

US Classification:

44445

US Patent:

H12386, Oct 5, 1993

Filed:

Mar 8, 1993

Appl. No.:

8/028706

Inventors:

Michael R. Duncan - Yorkville IL

Assignee:

Caterpillar Inc. - Peoria IL

International Classification:

B60G 100

US Classification:

280688

Abstract:

Vehicles that are frequently operated in "off road" conditions are normally equipped with a means by which some form of oscillation is provided to accommodate the uneven terrain over which it traverses. In some instances, the stability of the vehicle is inadequate while in other instances the stability is acceptable; however, the service life of the particular design is in question. The axle suspension 10 of the present invention is mounted to the vehicle frame 12 in a manner whereby the various types of forces encountered during the operation of the vehicle are directed to specific areas of the mounting. Being so directed, the mounting members 38 and 52, utilized in these specific areas of mounting, may be selected to best accommodate the type of loading that will be applied in that area.

US Classification:

252455R

Abstract:

A process for the formation of a catalyst of predetermined pore size distribution and pore volume from an alumina hydrogel formed and obtained by precipitation from a solution containing a hydrous form of alumina in 1-5 wt. % concentration and an anion that is soluble in an alkaline solution and forms an aluminum salt, at pH 8-12, and temperature ranging about 15. degree. F. -120. degree. F. , and then extended by contact with a water-soluble polymer containing from 2 to about 24 monomer units from the group consisting of (a) polyethylene glycols, (b) polypropylene glycols, and (c) polyethylene amines sufficient to absorb the polymer and displace water from the pores until the weight ratio of polymer:alumina ranges about 0. 5:1 to about 4:1. The so formed alumina hydrogel in a series of steps, inclusive of the polymer extending step, is blended with make-up and recycle polymer for displacement of water and incorporation of the polymer, spray dried to convert the hydrogel to essentially boehmite powder of microspherical form, the boehmite powder mulled with water to form a paste, and the paste extruded to form extrudates.
