Patent number: 8450512Abstract: Disclosed herein are methods for a simple process to make 3-aminoorgano functional silanes and siloxanes, free from isomers, by the use of commonly available materials. One embodiment of such a method comprises reacting aminoorgano functional silanes with hexamethyldisilazane in the presence of an acidic catalyst to produce a cyclic gamma-functional aminoorganic silane and beta isomers; separating the cyclic gamma-functional aminoorganic silane and the beta isomers; and converting the separated cyclic gamma-functional aminoorganic silane to pure gamma-aminoalkylsilane or pure aminoorganic siloxane. Also disclosed herein are cyclic derivatives of gamma-functional aminoorganic silanes.Type: GrantFiled: September 8, 2010Date of Patent: May 28, 2013Assignee: Genesee Polymers CorporationInventors: Charles Piskoti, Charles R.

Patent number: 6372160Abstract: A process for preparing a mold used for producing, for example, high resilience polyurethane foamed articles, comprises the step of spraying an aqueous release compound on the inner, article-contacting surface of the mold, the release compound including: an aqueous carrier; and a release agent which forms a release film on the article-contacting surface, wherein the release film is formed by evaporating a majority of the aqueous carrier. An aqueous rinse solution is gently sprayed on the inner mold surface after formation of the release film. The rinse solution, now carrying residual water, emulsifier(s) and/or contaminants, is mechanically removed via an air entrainment device before significant evaporation of the rinse solution has taken place.Type: GrantFiled: June 14, 1999Date of Patent: April 16, 2002Assignee: Genesee Polymers CorporationInventor: Steven S. Kendall

Patent number: 5696173Abstract: The invention comprises processes for the production of useful fluid or grease from curable silicone compositions or silicone rubbers, preferably reclaimed or scrap silicone rubber. The processes involve the application of energy in such a manner that a un-curable silicone grease or liquid that contains essentially all of the original material is produced from curable silicone compositions and grease or liquid is produced from silicone rubbers. Suitable energy forms include thermal and mechanical. The fluid or grease produced by the processes are useful as raw materials for the manufacture of silicone products such as: antifoam compounds (defoamers), greases, conformal coatings or rubbers. The materials produced by these processes were unexpectedly found to have exceptional antifoam properties without requiring the addition of other materials or further processing.Type: GrantFiled: May 1, 1996Date of Patent: December 9, 1997Assignee: Genesee Polymers CorporationInventor: Steven S. Kendall

Patent number: 5013808Abstract: A method of preparing an alkoxysilane and a silicone resin includes the steps of combining a siloxane A having a first boiling point with a catalyst in a reaction vessel. A tri or tetra alkoxy functional silane monomer B is added to the vessel having a second boiling point. The contents of the vessel are heated. By a rearrangement reaction, an alkoxysilane is distilled from the vessel. The alkoxysilane has a boiling point which is lower than the mixture of the boiling points of the siloxane A, the silane monomer B and the temperature of the heated vessel. A silicone resin having alkoxy functionality and no silanol functionality is recovered from the vessel.Type: GrantFiled: June 7, 1988Date of Patent: May 7, 1991Assignee: Genesee Polymers CorporationInventor: Charles Piskoti

Patent number: 4884641Abstract: A backhoe assembly (10) comprises a boom (12) for pivotal attachment to a machine (11). A bucket (14) is pivotally supported by the boom (12) for rotation about a support axis (16). A hydraulic cylinder (34) having a piston rod (36) raises and lowers the boom (12) and rotates the bucket (14) about the support axis (16) between an open and closed position. The assembly (10) is characterized by a hammer (20) supported in a cantilevered fashion for pivotal movement about the support axis (16) by the bucket (14) between a cocked position on a cocked side of an over-center position and a released free-fall position on the other side of the over-center position.Type: GrantFiled: December 30, 1985Date of Patent: December 5, 1989Assignee: Genesee Polymers CorporationInventor: Steven S. Kendall

Patent number: 4797445Abstract: A method of preparing an organo-alkoxy substituted silicone resin including the steps of reacting an organo-silicone resin containing hydroxy terminated functional groups with an alkoxy silane in the presence of catalytic amounts of a titanate compound and incubating the mixture to derive the organo-alkoxy substituted silicone product and an hydroxylated biproduct. The organo-alkoxy substituted silicone product may be reacted with a hydroxy functional fluid in the presence of catalytic amounts of a titanate compound to derive a non-transferable, semipermanent release agent.Type: GrantFiled: April 4, 1988Date of Patent: January 10, 1989Assignee: Genesee Polymers CorporationInventor: Charles Piskoti

Patent number: 4785067Abstract: A protective coating consists essentially of a polysiloxane copolymer characterized by being prepared by the reaction of a trimethyl end blocked polyamine silicone fluid including amino alkyl groups with a saturated aliphatic carboxylic acid to produce a polysiloxane copolymer including alkyl amine groups and either amide groups or amine salts or the combination thereof. The polysiloxane copolymer is utilized alone or with additives to produce a high gloss detergent resistant, and rust protective coating.Type: GrantFiled: March 25, 1987Date of Patent: November 15, 1988Assignee: Genesee Polymers CorporationInventor: Douglas R.
