Abstract:
A seamed flexible belt (30) having a substrate (60), a seam (31) having interlocking seam members (64,65), and an optional overcoat (66), wherein the interlocking seam members are held together by an adhesive (63) having a resistive, hot-melt processible, thermosetting resin and carbon filler (62), for use as intermediate transfer belt of electrostatographic, contact electrostatic, digital and other like machines.
Abstract:
An adhesive having a resin selected from polyvinyl butyral resins, phenolic resins, epoxy resins, and mixtures thereof, and at least one type of filler such as a carbon filler, for use in seaming components useful in electrostatographic, contact electrostatic, digital and other like machines.
Abstract:
An electrical component which has at least one end for electrically contacting another component. The electrical component includes a support with a plurality of electrically conductive fibers having at least a portion thereof extending outwardly therefrom to form a brush-like structure. The free end of the brush is adapted to contact the other component. A laser beam cold cuts the free end to minimize heating of the fibers being cut. A brush of this type may be used as a commutator brush in a scavengeless development system of an electrophotographic printing machine.
Abstract:
A method of forming at least one electrically conductive path in a thermoplastic substrate (26) having a melting point below 325°C, by synchronously depositing on the substrate in the predetermined pattern of said conductive path from an atomized stream of a precursor (28) of a catalyst for the electroless deposition of conductive metals and locally heating the deposited precursor in the pattern corresponding to the conductive path, the catalyst precursor (28) having a decomposition temperature below the melting point of the thermoplastic and within the temperature range where the thermoplastic softens, heating the portion of the thermoplastic substrate corresponding to said conductive path to a temperature sufficient to decompose said catalyst precursor (28) to the catalyst (30) and soften the thermoplastic; said substrate, catalyst precursor and temperature being selected such that on heating to the temperature the precursor decomposes to the catalyst, the thermoplastic softens and at least partially melts without substantial decomposition to enable the catalyst (30) to penetrate the surface of the thermoplastic and become anchored thereto to provide nucleation sites for the subsequent electroless deposition of conductive metal (31) and depositing conductive metal by electroless deposition on the heated portion to form the conductive path.
Abstract:
A pultruded composite member (23) having a longitudinal axis comprising a plurality of reinforcing fibers in a solid polymer matrix, said member having embedded at least one functional feature having been incorporated therein during its manufacture. The manufacturing process comprises providing a heated die (17) and a bath (14) of liquid polymer, simultaneously pulling continuous reinforcing fibers (12) and at least one carrier tape (25) with the functional feature on it through the liquid bath (14) and into and through the heated die (17).
