Appl. No.:

13/448271

Raymond E. Foscante - Yorba Linda CA, US
Neil Maynard Johnson - Richmond Heights OH, US

Douglas Malcolm Harless - Belle Mead NJ, US

Assignee:

BUNGE AMORPHIC SOLUTIONS LLC - White Plains NY

International Classification:

C01B 25/36
C09D 5/00
C08K 3/32

US Classification:

524417, 106401, 423311

Abstract:

APs are made by binary condensation via base-to-acid or acid-to-base routes. In the base-to-acid route, an aluminum hydroxide slurry is added to phosphoric acid that reacts to produce an aluminum phosphate condensate. In the acid-to-base route, phosphoric acid is added to an aluminum hydroxide slurry that reacts to produce an aluminum phosphate condensate. In an alternative base-to-acid route, an acidic aluminum phosphate is first made by adding phosphoric acid to a first amount of aluminum hydroxide slurry, and such acidic aluminum phosphate is added to a remaining amount of aluminum hydroxide slurry to react and produce an aluminum phosphate condensate. The reactions can be controlled to form an in-situ layered aluminum phosphate. So-formed APs can be amorphous, crystalline, or a combination thereof, and have low oil absorption and surface area, making them particularly useful in such end-use applications as extender pigments in coating compositions, replacing up to 70 wt % of TiO.

Assignee:

Bicron Corporation - Newbury OH

International Classification:

B91D 900
C01D 316

US Classification:

23296

Abstract:

A multistage process for the separation and purification of a desired crystalline material by repeated dissolution and recrystallization, wherein crystals and solvent move countercurrent to one another through the stages. A fluid temperature gradient is maintained within each recrystallization unit to make use of convection to facilitate or accelerate concurrent dissolution and recrystallization within a single vessel. Solid recrystallized material is moved from one unit to the next unit. An automated apparatus and a manually operated apparatus for carrying out the process are also described.

Traction Research, Inc. - Chardon OH

International Classification:

B62D 5512
B62D 5516
B62D 5524

US Classification:

305 9

Abstract:

A relatively low-cost, lightweight vehicle has a traction belt drive system, a force-spreading air bag suspension, and operational efficiency features. The traction belt cooperates with track wheel assemblies on each side of the vehicle to spread the suspension forces and to provide efficient steering ability. Each traction belt can be in the form of a Moebius strip. The air bag suspension uses integral air bags on each side of the vehicle cooperative with plural flaps pivotable on a central keel to spread varying suspension forces and to smooth the ride over a variety of terrains. The vehicle lends itself to efficient relatively low cost manufacturing techniques using standard materials.

Appl. No.:

Inventors:

Neil M. Johnson - Chardon OH

International Classification:

F01L 3302

US Classification:

91194

Abstract:

A rotating and reciprocating positive displacement mechanism which draws in a metered volume of gas and then expands or compresses that quantity of gas before expelling it. The mechanism has useful application as a compressor, a compressed gas motor, an expanding vapor engine, or a hot gas engine, where generation of heat by combustion can be either internal or external to the expansion mechanism. The primary advantages of the mechanism over conventional mechanisms used in these applications include (1) few moving parts, (2) easily constructed parts of simple geometry, (3) feasibility of compound operation (i. e. two-stage expansion or compression), (4) relatively constant input or output torque throughout the operating cycle, and (5) relative absence of high pressure peaks during the operating cycle (even when used as an internal combustion engine).
