Patent number: 5612399Abstract: A processable blend having high temperature and thermal shock resistance properties includes a resin blend which includes at least one first silicone polymer and at least one second silicone polymer. The processable blend is ceramitizable at a temperature above about 1100.degree. F. A method of producing an article with high temperature and thermal shock resistance properties includes forming a silicone blend of at least one first silicone polymer and at least one second silicone polymer, wherein the blend is ceramitizable at a temperature above about 1100.degree. F.; forming the blend into the shape of the desired article; and, at least partially curing at least one of said silicone polymers at a temperature below the ceramitization temperature.Type: GrantFiled: June 5, 1995Date of Patent: March 18, 1997Assignee: Hitco Technologies, Inc.Inventors: Don A. Beckley, John Stites

Patent number: 4468497Abstract: A novel bis-imide matrix resin system especially useful for high temperature, high performance, graphite fiber composites is disclosed. Microcracking of composites is reduced and transverse strength is increased by the addition to the resin system of 1 to 15 percent of compatible elastomers, such as polyether sulfones, bis-phenol linear homopolymeric epoxies or polyacrylic esters. The resin system comprises 50 to 95 percent by weight of ethylenically unsaturated bis-imides, preferably a low melting mixture of a major portion of maleimides of aromatic amines with a minor portion of maleimides of an aliphatic amine and 5 percent to 35 percent by weight of a diunsaturated low-temperature cross-linking agent such as divinyl benzene which gels the bis-imide at low temperatures. Room temperature tackiness, heat resistance and cross-link density are improved by the presence of 1 to 10 percent of a trifunctional curing agent.Type: GrantFiled: January 24, 1983Date of Patent: August 28, 1984Assignee: HitcoInventors: Sidney W. Street, Don A. Beckley

Patent number: 4377657Abstract: A novel bis-imide matrix resin system comprising 50 to 95 percent by weight of ethylenically unsaturated bis-imides, preferably a low melting mixture of a major portion of maleimides of aromatic amines with a minor portion of maleimide of an aliphatic amine and 5 percent to 35 percent by weight of a diunsaturated low-temperature cross-linking agent such as divinyl benzene which gels the bis-imide at low temperatures. This reduces stress between the matrix resin and the surface of the reinforcing fiber, thus reducing the tendency to form microcracks. Microcracking is further reduced and transverse strength is increased by the addition of 0 to 15% of compatible elastomers to the resin and cross-linking agent. Room temperature tackiness, heat resistance and cross-link density are improved by the presence of 0 to 10% of a trifunctional curing agent.Type: GrantFiled: March 30, 1981Date of Patent: March 22, 1983Assignee: HITCOInventors: Sidney W. Street, Don A. Beckley

Patent number: 4369104Abstract: Improved graphite composite electrodes are provided by dispersing within the matrix resin spaced, collimated graphite fibers having a diameter below 30 microns in a direction perpendicular to the face of the electrode plate. The electrodes are particularly useful in the disinfection of aqueous liquids with low power consumption and with very low ablation of the surface of the electrode.Type: GrantFiled: October 22, 1979Date of Patent: January 18, 1983Assignee: HitcoInventor: Don A. Beckley

Patent number: 4322464Abstract: A high temperature woven refractory fabric is coated by preheating the surface of the fabric by means of actinically matched radiation, suitably infra-red, and then fusion-bonding the inner surface of a thermoplastic film such as polyurethane to at least one surface of the fabric to fusion-bond the film thereto. The warm fusion-bonded film is then processed through a non-heated nip-roll assembly in which at least one of the rollers has a soft facing such as rubber which impresses the film into the interstitial fillweft woven intersections to form a fabric-appearing coated product. The infra-red wave length is selected for maximum absorption by the fabric and the intensity of the radiation and speed of the film are controlled to provide sufficient but not excessive fusion or melting of the film.Type: GrantFiled: May 24, 1978Date of Patent: March 30, 1982Assignee: HITCOInventor: Don A. Beckley

Patent number: 4265727Abstract: Improved graphite composite electrodes are provided by rendering the matrix resin conductive by dispersing therein 5 to 15% by weight of a conductive pigment and by uniformly dispersing therein randomly oriented graphite fibers having a diameter below 30 microns and a length no more than 1/2 the thickness of the electrode plate. The electrodes are particularly useful in the disinfection of aqueous liquids with low power consumption and with very low ablation of the surface of the electrode.Type: GrantFiled: October 22, 1979Date of Patent: May 5, 1981Assignee: HitcoInventor: Don A.
