Patent number: 6004417Abstract: A microencapsulatable solvent adhesive composition for coupling plastic conduits, such as pipes, connectors and related fittings comprises a water-insoluble polymer and a mixture of volatile organic solvents for the polymer, each of the solvents having 6 to 40 carbon atoms. This solvent adhesive composition is suitable for microencapsulation by aqueous-based microencapsulation processes. A plurality of microcapsules encapsulating the solvent adhesive composition are bound to a polymeric surface of a conduit, such as a pipe connector or fitting, by a binder composition, to form a surface coated with a layer of rupturable microcapsules. When the microcapsules are ruptured upon joining of the coated conduit to a second conduit, the volume of the released solvent adhesive composition is sufficient to cement the surfaces together.Type: GrantFiled: January 20, 1998Date of Patent: December 21, 1999Assignee: The Lamson & Sessions Co.Inventors: Mark A. Roesch, David A. Maccarone, Gary F. Hillenbrand, Morris F. Newsom, Roland M. Lynch

Patent number: 5153634Abstract: An imaging system in which images are formed by image-wise exposing a layer containing a chromogenic material and a photosensitive composition in which at least the photosensitive composition is encapsulated in a lyer of pressure rupturable capsules. Exposure and capsule rupture renders the chromogenic material image-wise accessible to the developer for a patterned image forming reaction.Type: GrantFiled: March 15, 1989Date of Patent: October 6, 1992Assignee: The Mead CorporationInventors: Frederick W. Sanders, Gary F. Hillenbrand, Jonathan S. Arney, Richard F. Wright

Patent number: 5053309Abstract: A color image forming process wherein images are formed by reaction of cyan, magenta and yellow color precursors with a developer material, the reaction is image-wise controlled by image-wise exposure of a photosensitive composition encapsulated in pressure rupturable capsules, image-wise exposure of the photosensitive composition and rupture of the capsules releases the color precursor for patterned reaction with the developer material.Type: GrantFiled: March 22, 1990Date of Patent: October 1, 1991Assignee: The Mead CorporationInventors: Frederick W. Sanders, Gary F. Hillenbrand, Jonathan S. Arney, Richard F. Wright

Patent number: 4940645Abstract: Imaging materials employing photosensitive microcapsules having improved film speed are disclosed wherein the microcapsules contain a photoinitiator system including an absorber, a coinitiator and an autoxidizer; the absorber is a compound such as an aromatic ketone, the coinitiator and the autoxidizer are different but may be compounds such as N,N-dialkylanilines; the coinitiator and autoxidizer are selected such that free radical generation and oxygen consumption occur with optimum efficiency thereby providing an imaging material having high film speed.Type: GrantFiled: January 19, 1989Date of Patent: July 10, 1990Assignee: The Mead CorporationInventors: Paul D. Davis, Gary F. Hillenbrand, Paul C. Adair

Patent number: 4399209Abstract: A transfer imaging system is disclosed wherein images are formed by image-wise exposing a layer comprising a chromogenic material and pressure rupturable capsules containing, as an internal phase, a photosensitive composition. In a preferred embodiment, the chromogenic material is encapsulated with the photosensitive composition. Upon exposure and capsule rupture the chromogenic material is image-wise transferrable to a developer or copy sheet where the chromogenic material reacts with a developer to form an image. Preferred systems are sensitive to U.V. or blue light in the wavelength range of 380 to 480 nm.Type: GrantFiled: November 12, 1981Date of Patent: August 16, 1983Assignee: The Mead CorporationInventors: Frederick W.
