    Abstract: A method of making an electrically conductive polyurethane elastomer that is substantially free of bubbles and foreign particles comprising: forming a prepolymer of a polyol and an isocyanate, forming a liquid mixture of an ionic conductive additive and amounts of cross linking agent and chain extenders sufficient to provide a crosslinked elastomer; filtering the liquid mixture of additive, crosslinking agents and chain extenders to remove foreign particles; preheating the liquid mixture to a temperature below the decomposition temperature and above the melting temperature of the additive, crosslinking agents and chain extenders in a degassing oven to degass to less than 5 mm of mercury to break any bubbles in the mixture and remove moisture; to a vacuum reactor mixer having two input ports, adding the prepolymer and the preheated degassed liquid mixture and mixing under a vacuum of less than 5 mm of mercury of a period of time to provide a uniform mixture: removing the mixture from the vacuum reactor mixer and forming it into the desired shape; and curing the formed shape to an elastomer substantially free of bubbles and foreign particles.

    Abstract: An intermediate transfer belt with a mechanically and electrically invisible seam formed by joining two ends of the belt at a seam. Two regions of the belt are thus formed, a seam region at and around the seam and a far region away from the seam. The seam region has good electrical property correspondence (as explained in the patent) with the far region and a lateral resistivity greater than 10 ohms/square. The joining of the belt can occur along a kerf.

    Abstract: A non-contacting electrostatic measurement apparatus including a vibratory element (32) and an electrode (34), affixed to the vibratory element, suitable for sensing a capacitive coupling relationship with an electrostatic field to produce a signal indicative of the magnitude of the electrostatic field. The signal is transmitted to signal processing circuitry via conductive fibers (50), such as carbon fibers, so as to impose little mechanical loading on the vibrating electrode. The electrode may be either unshielded, for an electrically floating electrostatic voltmeter, or shielded, for an electrostatic voltmeter employing electrically grounded components.

    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.
