20080142725, Jun 19, 2008

Filed:

Oct 18, 2006

Appl. No.:

11/550579

Inventors:

Frank Sanns - Pittsburgh PA, US

International Classification:

G01K 1/08

US Classification:

250398

Abstract:

A device for accelerating ions between a potential towards a central point in space is disclosed. The device can be used to accelerate ions along a collision path with other accelerated ions or other present particles resulting in a nuclear fusion reaction. The device improves upon the prior art by using a plasma as one of the electrodes forming the potential.

Filed:

Jul 24, 1992

Appl. No.:

7/920219

Inventors:

Frank Sanns - Pittsburgh PA

Assignee:

Bayer Corporation - Pittsburgh PA

International Classification:

C08K 334
C08K 700
C08L 7502
C08L 7504

US Classification:

524449

Abstract:

In accordance with the invention, a reinforcing agent is added to the polyol side before the Reaction Injection Molding (RIM) process. The agent of the invention comprise particulate flakes which are characterized by their fine particle size and high aspect ratio. It was surprisingly found that the incorporation of the agent of the invention in the RIM process yields molded parts with a good combination of properties including flexural and tensile modulus heat sag and reduction in the coefficient of linear thermal expansion and high Distinctness Of Image (DOI) values.

Frank Sanns - Pittsburgh PA
Richard W. Mitesser - Pittsburgh PA
Merle W. Lesko - McDonald PA
Randall C. Rains - Pittsburgh PA

Assignee:

Bayer Corporation - Pittsburgh PA

International Classification:

B29C 4514

US Classification:

2643281

Abstract:

The invention is directed to a process for preparing a Class-A surface, fiber reinforced molded article. The process broadly requires the use of two separate fiber surfacing veils with a fiber reinforcement sandwiched therebetween. A polyurethane reaction system is injected into the mold. The system requires the presence of specified hindered amines.

International Classification:

C08G 1808
C08J 900

US Classification:

521163

Abstract:

The present invention is directed to a process for the production of optionally cellular, polyurea elastomer moldings by reacting a reaction mixture containing I) a polyisocyanate, II) a polyether having at least two isocyanate-reactive groups and a molecular weight of 1800 to 12,000 in which at least 50% of the isocyanate-reactive groups are primary and/or secondary amino groups, III) about 5 to 50% by weight, based on the weight of component (II) of a chain extender comprising a sterically hindered aromatic diamine and IV) about 0. 5 to 20% by weight, based on the weight of components (II) and (III) of a zinc carboxylate containing from 10 to 14 carbon atoms per carboxylate group, and the reaction mixture is processed at a one-shot system by the RIM process at an isocyanate index of about 70 to 130. The present invention is also directed to an isocyanate-reactive component for use in a RIM process based on components (II), (III) and (IV).

International Classification:

C08G 1810

US Classification:

528 60

Abstract:

The present invention is directed to polyurethane moldings produced via the RIM process. These polyurethane moldings have excellent reactivity, demold properties (at a 30s demold), and good elongation and tear strength, and comprise the reaction product of an HDI prepolymer having an NCO content of 5 to 25%, a functionality of less than 2. 3, and a monomer content of less than 10%, with an isocyanate-reactive component comprising b1) at least one relatively high molecular weight organic compound containing at least about two isocyanate-reactive hydroxyl groups; b2) at least one relatively low molecular weight organic compound selected from the group consisting of diols, aminoalcohols, and mixtures thereof; and b3) at least one relatively low molecular weight hydroxyl-based crosslinking compound containing no more than one aliphatic amine hydrogen atoms capable of reacting with isocyanate groups; in the presence of at least one catalyst.

Abstract:

The present invention is directed to a process for the production of optionally cellular, polyurea elastomer moldings by reacting a reaction mixture containing (I) a polyisocyanate, (II) a polyether having at least two isocyanate-reactive groups and a molecular weight of 1800 to 12,000 in which at least 50% of the isocyanate-reactive groups are primary and/or secondary amino groups, (III) about 5 to 50% by weight, based on the weight of component (II) of a chain extender comprising a sterically hindered aromatic diamine and (IV) about 1 to 20% by weight, based on the weight of components (II) and (III) of an active hydrogen-containing fatty acid ester having a molecular weight of about 500 to 5000 and prepared by reacting an alcohol with an aliphatic, saturated or unsaturated fatty acid, said ester being characterized in that at least one aliphatic acid which contains more than eight carbon atoms is built into the molelcule, said ester further characterized as having an acid number of 0 to 100 and a hydroxyl number of 0 to 150 with at least one of said numbers being greater than 0, wherein the fatty acid ester is initially blended with component (II), component (III) or a mixture thereof and the reaction mixture is processed as a one-shot system by the RIM process at an isocyanate index of about 70 to 130. The present invention is also directed to an isocyanate-reactive component for use in a RIM process based on components (II), (III) and (IV).
