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:
Imageable seamed intermediate transfer belts having a large seam surface area, and marking machines that use such imageable seam intermediate transfer belts. A belt is formed from an electrically semiconductive substrate (10) having a first end and a second end that are mated to form a seam (11). The first end includes a first tongue (27) and the second end includes a second tongue (28) that form a rabbeted joint such that the outer surface of the belt is substantially smooth across the seam. An adhesive is disposed over the rabbeted joint. The tongues may include mechanical locking features, such a protrusion and a channel, or an interlocking puzzle-cut feature that mate. The mechanical locking features may be continuous along the seam.
Abstract:
Seamed belts, particularly puzzle-cut imageable seam intermediate transfer belts, and marking machines that use such belts, that have a beveled sides across the thickness of the belt. When the first and second ends are interlocked the bevel points are adjacent one another and a substantially V-shaped channel is formed. An adhesive is disposed in that channel. The V-shaped channel beneficially continuously extends along the puzzle-cut seam.
Abstract:
An electrical component including a plurality of electrically conductive fibers in a matrix, wherein the matrix is prepared from a composition including a methyl methacrylate monomer and a modified bisphenol monomer, wherein the electrical component has a region at least substantially free of the matrix to provide a plurality of electrical contact points.
Abstract:
A frame assembly for affording mechanical support and for carrying electrical conduction paths for connection to circuitry of a machine. The frame assembly includes members (50) comprising pultrusions having an insulating body (51,56) and reinforcing fibers (59) within the insulating body, and has grooves in surface portions along an elongated dimension with conductors (70-74) in the grooves. The conductors provide electrical conduction paths that are connectable to circuitry of the machine. The pultrusion may be a thermal setting polymer, for example, selected from the group consisting essentially of polyester, vinyl ester, and epoxies, and may be reinforced with fiberglass. The frame member can also have a hollow interior portion (53) within which conductors (60-62) are arranged to conduct AC power to the circuitry of the machine, and the conductors on the exterior surface of the frame member can be arranged to conduct IIOC bus signals. When a plurality of the frame members are connected together to form a frame assembly, corresponding conductors of each are interconnected to facilitate supplying and directing the electrical signals to the machine. The connections can be made to and among the electrical conductors carried by the pultrusions by blocks that are attachable to the pultrusions.
Abstract:
A high voltage connector is formed of a composite pultruded member (10) that has an inner core (11) including a plurality of high resistance electroconductive strands (15) carried in a resin binder. The inner core (11) is surrounded by an outer nonconductive shell (14), and extends from a laser cut end (18) of the outer shell (14) to a contact face (20). During formation of the contact using laser techniques, portions of the outer shell (14) are removed to expose the inner core (11), the resin binder of the inner core (11) may be removed, and the strands (15) of the inner core (11) may be fibrillated and patterned as desired. In one embodiment, the resistance of the strands of the inner core of the high voltage connector provide a load resistor for a circuit to which the connector may be connected.
