  • Patent number: 5486578
    Abstract: The present invention relates to curable silicone coatings containing silicone resins. More particularly the present invention relates to curable silicone coating compositions comprising an olefinic organopolysiloxane, an organohydrogensiloxane, a platinum catalyst, and silicone resins in which the resins are prepared by a continuous method whereby the ratio of reactants is kept constant thus producing less variation in the final silicone resin that is produced. The silicone resins provide beneficial release properties when added to curable silicone coating compositions.
    Type: Grant

  • Patent number: 5391673
    Abstract: The present invention relates to methods for making silicone resins. More particularly, the present invention relates to methods for producing silicone resins comprising monofunctional units in the form of R.sub.3 SiO.sub.1/2 units and tetrafunctional units in the form of SiO.sub.4/2 units. The methods of the present invention are characterized by a continuous process for producing silicone resins while maintaining a constant ratio of reactants thus producing less variation in the final product. The present invention is further related to the compositions produced by the methods of this invention.

  • Patent number: 5183684
    Abstract: Ceramic or ceramic-like single, two, or multilayer coatings having aluminum nitride as one of the layers are provided, including methods for the preparation of such coatings which produce planarizing, passivating and hermetic barrier coatings on temperature sensitive substrates such as semiconductors and electronic devices. The aluminum nitride ceramic or ceramic-like coating is provided by applying a liquid alkylaluminum amide having the formula (R.sub.2 AlNH.sub.2).sub.3, where R is an alkyl group containing from 1 to 4 carbon atoms, neat or diluted in an organic solvent. The liquid coating is then dried, followed by heating the coating to a temperature of between about 400.degree. to about 100.degree. C. in the presence of ammonia to produce an aluminum nitride-containing ceramic coating.

  • Patent number: 5116637
    Abstract: This invention relates to a low temperature method of converting coatings of hydrogen silsesquioxane resin or hydrolyzed or partially hydrolyzed R.sub.X Si(OR).sub.4-X to ceramic silica coatings. The method comprises applying a silica precursor coating to a substrate, exposing the coating to an environment comprising an amine and subjecting the coating to a temperature sufficient to yield the ceramic coating. The methods of the invention are particularly applicable to applying coatings on electronic devices.

  • Patent number: 3931883
    Abstract: A device for driving loads on a horizontal roller conveyor support between pick-up and delivery stations including a carriage mounted to travel back and forth below the conveyor level. The lower end of an upstanding lever arm is pivoted on the carriage and at the upper end of the arm a load engaging cylinder or roll is mounted with its axis forwardly (i.e. in a downstream direction) adjacent the vertical center line of the arm which is yieldably urged to remain at right angles to the plane of conveyor support. In the latter position the top of the roll is slightly elevated by a fraction of an inch above said load support plane. In operation at the pick-up station near the upstream end of carriage travel the roll can freely rotate under a load and the lever is thereby angularly set at an acute angle in the load driving direction.
